In the Chinese tradition, the relationship between art and philosophy is conceptually explored in terms of the relationship between dao (Tao) and wen, which may respectively be viewed as representing philosophy and art. Over history, discourses on dao 道 and wen 文 are central to studies of Chinese literature, art, culture, and civilization. But just as dao holds a range of ideas in Chinese philosophy, wen is also one of the most complex terms in Chinese tradition, whose denotations and connotations are multifaceted and open to interpretations. This article argues that the elusive nature of wen can be understood adequately from the perspective of language philosophy and aesthetics via its relationship to the metaphysical principle of the Dao. By examining the discourses on wen and dao, this article advances a thesis with three interrelated ideas: (1) wen (writing) as manifestations of the Tao is an instance of “humanized nature”; (2) the birth of wen marked the beginning of reflections on literature and art, hence inaugurating aesthetics in the Chinese tradition; and (3) the early discourses on wen have determined the distinctiveness of Chinese aesthetic consciousness.

In some supply chains, materials are ordered periodically according to local information. This paper investigates how to improve the performance of such a supply chain. Specifically, we consider a serial inventory system in which each stage implements a local reorder interval policy; i.e., each stage orders up to a local base-stock level according to a fixed-interval schedule. A fixed cost is incurred for placing an order. Two improvement strategies are considered: (1) expanding the information flow by acquiring real-time demand information and (2) accelerating the material flow via flexible deliveries. The first strategy leads to a reorder interval policy with full information; the second strategy leads to a reorder point policy with local information. Both policies have been studied in the literature. Thus, to assess the benefit of these strategies, we analyze the local reorder interval policy. We develop a bottom-up recursion to evaluate the system cost and provide a method to obtain the optimal policy. A numerical study shows the following: Increasing the flexibility of deliveries lowers costs more than does expanding information flow; the fixed order costs and the system lead times are key drivers that determine the effectiveness of these improvement strategies. In addition, we find that using optimal batch sizes in the reorder point policy and demand rate to infer reorder intervals may lead to significant cost inefficiency.

Recommending books to readers of contemporary mainstream, or literary, fiction is perhaps the most challenging of all endeavors for readers' advisors. Pearl and her co-authors attempt to ease the process with this helpful guide to the most elusive genre. Covering 1,000 novels, many of them award winners, the book organizes titles according to their major appeal characteristics (e.g., language, setting, story, and character) as delineated by Saricks and Brown in their standard text, "Readers' Advisory Service in the Public Library, 2d ed., " (ALA, 1997). For each book there is a plot summary, indications on the book's suitability for book discussion groups, and recommendations of similar titles. Awards are cited as well, and all titles mentioned are indexed by title, author, and subject. Describing some of the best literature published in the United States and abroad in recent years, this book is an essential guide for readers' advisors, and a helpful collection development tool.

Litigation in otolaryngology in England was the subject of a recent article in Clinical Otolaryngology by the ‘Getting it Right First Time’ (‘GRIFT’) group. The same group have contributed a sister article to this issue of The Journal of Laryngology & Otology, which focuses on litigation in otology, updating the messages in an article in The Journal by Metcalfe and colleagues a few years ago. The most expensive claims were from stapedectomy (average of over £750 000; maximum total cost of over £4 million), and the main reasons for claims were: delay in or failure of treatment, delay in or failure of diagnosis, intra-operative complications, and inadequate consent. Given the Montgomery versus Lanarkshire case, which has been much discussed (but not always translated into proper change in process), the rise in consent-related litigation is hardly surprising, but combating this risk is in the hands of individual clinicians. Metcalfe and colleagues’ study showed that consent problems accounted for around 9 per cent of cases, and 57 per cent of claims were successful. The corresponding proportion in the more recent paper is 13 per cent of cases. The authors note that ‘On an individual level, auditing and reflecting on a surgeon’s consent process could act as a straightforward method for reducing the risk of litigation’. Delays in diagnosis and treatment are perhaps more of a concern, accounting for the biggest category of litigation, as the coronavirus disease 2019 (Covid-19) pandemic has inevitably caused a great spike in delays which is outside of the control of individual clinicians. The flow of articles on Covid-19 related matters continues, and this issue of The Journal revisits the matter of the natural history of smell and taste disorders during and after Covid-19 infection. Petrocelli and colleagues from Bologna, Italy, examined smell and taste in in-patients with severe acute respiratory distress syndrome, testing during the acute illness period (first 7 days), and then at one, two, three and six months. This paper compliments their previous articles, which explain their methods and give initial results. The authors found that at six months, 27 per cent of 300 subjects had persistent olfactory disturbance and 1 per cent had anosmia. The corresponding figures for taste were 10 per cent and 1 per cent respectively, with the improvement from baseline reaching a plateau at one month. Seventy per cent of patients had some chemosensory symptoms during the infection. A paper from Tehran, Iran, by Jalessi and colleagues, deals with a different group of patients, those who reported smell disturbance but had mild Covid-19 symptoms, rhinological symptoms or no accompanying symptoms at all (and so were ‘probable’ Covid-19 cases, not confirmed by polymerase chain reaction). The patients were followed up by telephone interview. In this study, 71 per cent of patients recovered completely within 5.5 months, and the presence of other nasal symptoms was associated with prolonged olfactory disturbance. Favourable prognostic factors were young age and gastrointestinal symptoms. A thoughtful ‘qualitative’ study from London, UK, is included this month, which examines a small number of ENT trainees and investigates their feelings about redeployment during the Covid-19 pandemic. This study should help in the planning of redeployment should future similar situations arise. Many aspects of the psychological effects are discussed, as well as the trainees’ feelings about their skill sets not being fully utilised. The camaraderie experienced in the new teams is noteworthy, but: ‘... this team spirit and senior support did not stop the interviewed trainees reporting a high emotional toll from the experience, mirroring that described by other groups of redeployed surgeons’. The need to use an otolaryngologist’s unique skill set in redeployment is a theme that resonates with other commentaries, as in a paper by Shipchandler and colleagues from the USA last year.

Telomeres are specialized chromatin structures that are situated at the end of linear chromosomes and play an important role in cell senescence and immortalization. Here, we investigated whether changes in histone signature influence the nuclear arrangement and positioning of telomeres. Analysis of mouse embryonic fibroblasts revealed that telomeres were organized into specific clusters that partially associated with centromeric clusters. This nuclear arrangement was influenced by deficiency of the histone methyltransferase SUV39h, LMNA deficiency, and the histone deacetylase inhibitor Trichostatin A (TSA). Similarly, nuclear radial distributions of telomeric clusters were preferentially influenced by TSA, which caused relocation of telomeres closer to the nuclear center. Telomeres also co‐localized with promyelocytic leukemia bodies (PML). This association was increased by SUV39h deficiency and decreased by LMNA deficiency. These differences could be explained by differing levels of the telomerase subunit, TERT, in SUV39h‐ and LMNA‐deficient fibroblasts. Taken together, our data show that SUV39h and A‐type lamins likely play a key role in telomere maintenance and telomere nuclear architecture. J. Cell.

This work focused on the advanced treatment of the secondary treated ethylene chemical plant effluent, which contained high conductivity and high organic concentration. To reduce the cost and improve operation stability, a biological aerated filter-ultrafiltration-reverse osmosis (BAF-UF-RO) process was proposed. The feasibility and effectiveness of the BAF loaded with a novel non-sintered fly-ash ceramsite (NSFC) as pretreatment method were investigated in detail. The results showed that the COD, turbidity, NH3-N and SDI15 in the effluent from the BAF were reduced largely. The BAF-UF-RO process was stable with the recovery rate of 75%, and the desalination rate was up to about 97.5%. Moreover, the operating pressure and backwash frequency of RO maintained 0.94-0.98 MPa and 2 times/d, respectively. After continuous operation for four months, there appeared to be no need for chemical cleaning of the RO membrane.

Many bacteria interact with target organisms using syringe-like structures called Contractile Injection Systems (CIS). CIS structurally resemble headless bacteriophages and share evolutionarily related proteins such as the tail tube, sheath, and baseplate complex. Recent evidence shows that CIS are specialized to puncture membranes and often deliver effectors to target cells. In many cases, CIS mediate trans-kingdom interactions between bacteria and eukaryotes, however the effectors delivered to target cells and their mode of action are often unknown. In this work, we establish an in vitro model to study a CIS called Metamorphosis Associated Contractile structures (MACs) that target eukaryotic cells. We show that MACs kill two eukaryotic cell lines, Fall Armyworm Sf9 cells and J774A.1 murine macrophage cells through the action of a newly identified MAC effector, termed Pne1. To our knowledge, Pne1 is the first CIS effector exhibiting nuclease activity against eukaryotic cells. Our results define a new mechanism of CIS-mediated bacteria-eukaryote interaction and are a first step toward understanding structures with the potential to be developed as novel delivery systems for eukaryotic hosts.

Introduction: Surgical approaches to closure of post myocardial infarction ventricular septal defect (PIVSD) are associated with high morbidity and mortality. Timing of intervention for its closure remains controversial. Several studies advocate early operative intervention, after diagnosis of PIVSD but these are associated with high mortality. However, the strategy of delayed closure around 14 to 20 days or higher has been advocated in certain subsets of patients who can be stabilized from cardiogenic shock (CS) with pharmacological means with or without temporary mechanical circulatory support (tMCS). This helps to allow tissue fibrosis around PIVSD which increases the chance of operative success. Results of 5 such patients in whom surgery was moderately delayed, and 2 in whom early operation were performed are reported in this paper. Material and methods: Between May 2012 to April 2016, 7 consecutive patients of PIVSD had operative closure under cardio pulmonary bypass in our hospital. 5 patients had diuretic and inotrope responsive CS and had delayed closure of PIVSD within 12 to 20 days, while 2 with severe CS, who were supported preoperatively with tMCS like intra aortic balloon pump (IABP), had early closure within 72 hours. Patient data of these seven subjects were retrospectively collected, and the current status of the survivors was ascertained by out patient follow up. Results: 4 of 5 patients from delayed surgery group with small PIVSD survived while 1 patient had early mortality due to severe right ventricular dysfunction post operatively resulting in LCOS. 1 patient out of the 2 early surgery group with a large PIVSD survived while the other patient with a small PIVSD and an extensive MI had early post operative mortality. 1 had from late surgery group had delayed mortality after 3 years. 4 patients are living at present. Conclusion: We advocate delayed elective repair of PIVSD, in patients with CS who responded to aggressive conservative management maintaining hemodynamic stability, to allow inflammatory state to subside. In those patients with severe CS, additional rescue therapy with temporary mechanical circulatory support is needed to prevent further deterioration of systemic perfusion. If the severe CS is due to high left to right shunt rather than infarct size, prognosis after repair of PIVSD is better than in patients with CS due to extensive myocardial damage.

In the earlier work, Single Instance Single-Label Learning mechanisms are proved faster and converge for better results but the accuracy is the concern in the Intrusion Detection systems (IDS) in large scale data centric networks. Evolution of supervised training mechanisms have favored more accurate decision making, however failed to incorporate the dynamism of new instances which are in early stages and non-overlapping with current training data sets. This paper proposes a cascaded and hybridized mechanism involving Semi-supervised Multi-Instance Neurologic Adaptive Learning (SMI-NAL) mechanism. The objective is to estimate the threshold level of convergence and improve the system accuracy. In addition, the proposed learning mechanism reduces the computational complexity to achieve proactive measure which is the real challenging phenomenon. Compared to the conventional IDS process, the proposed learning mechanism improves the accuracy of IDS and updates the machine learning set (Training set) more appropriately and wrong decision making can beeliminated. The key features of IDS such as robustness, scalability and ease of use are achieved using the proposed learning mechanism.

To the Editor: —In reference to the article "Successful Treatment of Mismatched Blood Transfusion," by Varney et al. (J. A. M. A.145:978 [March 31] 1951), I believe certain facts regarding hemolytic transfusion reactions should be noted. I do not believe alkalinization of the urine is of any use in the treatment of anuria due to so-called lower nephron nephrosis, nor do I believe precipitation of acid hematin is an important factor in the causation of this condition. It has been shown that overburdening of the patient with intravenous fluids, in the amount indicated in the case report, is a most frequent cause of cardiac failure, pulmonary edema, and death. The important steps in the management of hemolytic transfusion reactions are first, relief of anoxemia by raising of the hemoglobin to normal values with transfusion of compatible whole blood or packed red blood cells; second, restriction of fluids to

Research on British immigrants in France emerged in the 1990s, focusing on their preference for residential migration to rural France for lifestyle reasons. This expanding population – in numbers and geographical distribution – attracted a second wave of research, a decade later, that increasingly showed the complexity involved in Britons’ motivations and experiences of integration in the host location. As well as deepening understanding of Britons in France, more recent studies have broadened the phenomenon by conceptualising these Britons as transnational migrants, lifestyle migrants and European Union citizens. This article reviews existing academic literature to examine the main issues and debates surrounding Britons in France, and chart agendas for future research.

Background Biomarkers are frequently used to estimate infarct size (IS) as an endpoint in experimental and clinical studies. Here, we prospectively studied the impact of left ventricular (LV) hypertrophy (LVH) on biomarker release in clinical and experimental myocardial infarction (MI). Methods and Results ST‐segment elevation myocardial infarction (STEMI) patients (n=140) were monitored for total creatine kinase (CK) and cardiac troponin I (cTnI) over 72 hours postinfarction and were examined by cardiac magnetic resonance (CMR) at 1 week and 6 months postinfarction. MI was generated in pigs with induced LVH (n=10) and in sham‐operated pigs (n=8), and serial total CK and cTnI measurements were performed and CMR scans conducted at 7 days postinfarction. Regression analysis was used to study the influence of LVH on total CK and cTnI release and IS estimated by CMR (gold standard). Receiver operating characteristic (ROC) curve analysis was performed to study the discriminatory capacity of the area under the curve (AUC) of cTnI and total CK in predicting LV dysfunction. Cardiomyocyte cTnI expression was quantified in myocardial sections from LVH and sham‐operated pigs. In both the clinical and experimental studies, LVH was associated with significantly higher peak and AUC of cTnI, but not with differences in total CK. ROC curves showed that the discriminatory capacity of AUC of cTnI to predict LV dysfunction was significantly worse for patients with LVH. LVH did not affect the capacity of total CK to estimate IS or LV dysfunction. Immunofluorescence analysis revealed significantly higher cTnI content in hypertrophic cardiomyocytes. Conclusions Peak and AUC of cTnI both significantly overestimate IS in the presence of LVH, owing to the higher troponin content per cardiomyocyte. In the setting of LVH, cTnI release during STEMI poorly predicts postinfarction LV dysfunction. LV mass should be taken into consideration when IS or LV function are estimated by troponin release.

Acute heart block is an uncommon but serious complication of myocardial infarction, though survivors usually return to sinus rhythm. Chronic heart block associated with Stokes-Adams attacks is also often assumed to be ischaemic in origin. Some clinical reviews have, however, stressed the high incidence of "primary" heart block (Zoob and Smith, 1963 ; Johansson, 1966). Initial studies from this hospital suggested that significant coronary artery disease was not present in most cases of chronic heart block and that pathological changes were often confined to the conduction system (Portal et al., 1962). A detailed post-mortem study of both acute and chronic heart block has now been carried out to define the part played by coronary disease in the production of complete heart block.

Helios hard red spring wheat (Triticum aestivum L.) has expressed high grain yield and medium time to maturity. The straw length and strength, volume weight, and seed size were intermediate to the check cultivars. It expressed resistance to prevalent races of stem rust and loose smut, intermediate resistance to common bunt and Fusarium head blight, and moderate susceptibility to leaf rust and leaf spots. It expressed resistance to pre-harvest sprouting and high Hagberg falling number. The end-use suitability of Helios was similar to that of the controls and, therefore, it is eligible for all grades of the Canada Western Red Spring (CWRS) wheat class.

Based on a patient's anti-hepatitis B virus (HBV) infection therapy clinical data of a new type of Chinese herbs (NTCH, consisting of 13 ingredients) plus adefovir dipivoxil, and our previous modified basic virus infection model [1], a new differential equation model with an immune variable is set up, and aims to describe and understand the dynamics of host cells, viruses, the immune system, as well as predict the long term curative effects. The results of numerical simulations of the model indicate that the dynamics of the model is agreement with in the patient's plasma HBV DNA levels. The model predicts that it need to eliminate all HBV virus in infected hepatocytes. Otherwise earlier cessation of the therapy will make the patients' plasma HBV DNA levels return.

Nowadays, control systems tend to rely on software more and more. Expensive sensors are replaced by smarter programs, which, in many cases, satisfactorily accomplish the same functions traditionally performed by the addition of more complex sensors or a greater number of them. The heavier load on the software side, also allows for greater flexibility and the ability to easily adapt to new requirements. In this paper, the performance of a low cost angular positioning system will be evaluated. This system is used to control a homemade goniophotometer, where mechanical components (including sensors and actuators) are given. The goniophotometer is C-g type. Movement around each axis is powered by induction motors, each with its gear reduction box, driven by frequency variators. Motors are mounted on the shafts of the equipment. Angular position measurements are performed by incremental encoders. The encoders are mounted on the shafts of the goniophotometer, too. The control and data acquisition software resides in a PC computer, equipped with function specific dedicated peripherals. These include an encoder signal processing card and another card to communicate with other instruments. To output control signals to the actuators, the PC parallel port is used. The objective is to determine if the inherent limitations of the system components (mechanical and instrumentation) can be attenuated or eliminated by the control software. Disadvantages associated to the existing equipment will be indicated, as well as the way to overcome them where it is possible; or the conditions that have to be met for this disadvantages to be tolerable, where it is not.

Information in networked systems often has spatial semantics: routers, sensors, or virtual machines have coordinates in a geographical or virtual space, for instance. In this paper, we propose a design for a spatial search system that processes queries against spatial information that is maintained in local databases inside a large networked system. In contrast to previous works in spatial databases and peer‐to‐peer designs, our design is bottom‐up, which makes query routing network aware and thus efficient, and which facilitates system bootstrapping and adaptation. Key to our design is a protocol that creates and maintains a distributed index of object locations based on information from local databases and the underlying network topology. The index builds upon minimum bounding rectangles to efficiently encode locations. We present a generic search protocol that is based on an echo protocol and uses the index to prune the search space and perform query routing. The response times of search queries increase with the diameter of the network, which is asymptotically optimal. We study the performance of the protocol through simulation in static and dynamic network environments, for different network topologies, and for network sizes up to 100 000 nodes. In most experiments, the overhead incurred by our protocol lies well below 30% of a hypothetical optimal protocol. In addition, the protocol provides high accuracy under significant churn.

BACKGROUND
Flavor rapeseed oil is a type of hot-pressed oil in China. In this work, physicochemical properties, oxidative stability index (OSI), tocopherols, sterols and polycyclic aromatic hydrocarbons (PAHs) in flavor rapeseed oils were evaluated. Additionally, the cancer risk assessment pertaining to PAHs in flavor rapeseed oil was investigated.
RESULTS
Acid values (0.64-2.68 mg KOH g-1 ), peroxide values (1.58-4.86 mmol kg-1 ) and color values (R=2.6-5.8, Y=35) of flavor rapeseed oils were all within codex limits. Tocopherols and sterols ranged from 559.5 to 783.7 and 4412.6 to 7859.8 mg kg-1 , respectively. The OSI (110 °C) was between 4.8 and 15.9 h, with an average value of 10.8 h. Mean values of benzo[a]pyrene and PAH4 (chrysene, benz[a]anthracene, benzo[b]fluroranthene, and benzo[a]pyrene) were 2.32 and 8.21 μg kg-1 , respectively. The 95% dietary exposure of BaPeq contents from PAH4 were 0.3474, 0.3942, 1.8293 and 0.4294 ng kg-1 day-1 for children, adolescents, adults and seniors of male, respectively. For the female, the above values were 0.3443, 0.3228, 1.8697 and 0.4084 ng kg-1 day-1 , respectively. Moreover, incremental lifetime cancer risk values at the cumulative probabilities of 91.3% and 91.6% for male adults and female adults, respectively, were higher than 1×10-5 .
CONCLUSION
Results implied that the potential risk of cancer with PAHs in flavor rapeseed oil should be concerned, especially the health of adults. Flavor rapeseed oil is still a product subject to contamination by PAHs. Limits for PAH4 of flavor rapeseed oil should be included in Chinese regulation to improve the safety.

ABSTRACT Anabaena variabilis fixes nitrogen under aerobic growth conditions in differentiated cells called heterocysts using either a Mo nitrogenase or a V nitrogenase. The nifH1 gene, which encodes the dinitrogenase reductase of the Mo nitrogenase that is expressed only in heterocysts, is cotranscribed with nifD1 and nifK1, which together encode the Mo dinitrogenase. These genes were expressed in the presence or absence of molybdate or vanadate. The vnfH gene, which encodes the dinitrogenase reductase of the V nitrogenase, was located about 23 kb from vnfDGK, which encodes the V dinitrogenase; however, like vnfDGK, vnfH was expressed only in the absence of molybdate, with or without vanadate. Like nifH1, the vnfH gene was expressed exclusively in heterocysts under either aerobic or anaerobic growth conditions and thus is under the control of developmental factors. The vnfH mutant was able to grow diazotrophically using the V nitrogenase, because NifH1, which was also made in cells starved for molybdate, could substitute for VnfH. Under oxic conditions, the nifH1 mutant grew in the absence of molybdate but not in its presence, using VnfH, while the nifH1 vnfH double mutant did not grow diazotrophically with or without molybdate or vanadate. A nifH1 mutant that expressed nifDK and vnfH but not vnfDGK was able to grow and fix nitrogen normally, indicating that VnfH could substitute for NifH in the Mo nitrogenase and that these dinitrogenase reductases are not involved in determining the metal specificity of the Mo nitrogenase or the V nitrogenase.

Zinc oxide is a promising optical material for possible application in solid state lighting. Highly transparent and nanocrystalline Zinc Oxide thin films with different concentration of Cadmium and Magnesium are deposited on corning 7059 glass by sol‐gel spin coating method. The transparent and homogeneous sol of 0.2 mol/l concentration is prepared by dissolving zinc acetate dihydrate in 2‐methoxyethanol. Monoethanolamine is used as sol stabilizer. The calculated amounts of cadmium acetate dihydrarte and magnesium acetate tetrahydrarte are added for doping. All the samples are annealed at 550 °C in air ambient for an hour. The doping is confirmed by X‐ray diffraction and the bandgap is measured by UV‐Vis spectroscopy. The bandgap successfully modulated from near ultraviolet region (3.29 eV) to far ultraviolet region (3.83 eV).

This study was aimed to investigate the relationship between expression of CD200 antigen and clinical characteristics in AML patients and to analyse the value of CD200 in evaluation of AML prognosis. The CD200 and immunophenotypes were detected by flow cytometry, the chromosome karyotypes were determined by R banding, the FISH was used to measure the AML1/ETO, PML/RARa and inv(16), and PCR technique was used to detect the fusion genes AML1/ETO and PML/RARα. The results showed that the positive rate of CD200 antigen expression in 54 patients was 57.4% (31/54), the CD200 antigen expression between sex and age of patients was no significant different (P > 0.05). There was significant difference of CD200 expression between CD34 and CD117 (P < 0.05), but the difference of CD200 expression in chromosome karyotypes was no significant difference(P > 0.05). Moreover, there was significant difference of CD200 expression in CD34 and CD117 of CBF positive AML patients (P < 0.05). It is concluded that the CD200 antigen expression in AML may associate with a poor prognosis of patients.

The article assesses South Africa's maritime power in the Indian Ocean. It is argued that South Africa needs a credible navy to exercise power and influence in support of foreign policy imperatives in the Indian Ocean. The maritime potential of other states which may have an impact on South Africa's interests is examined, including Australia, Malaysia, India, Pakistan and Kenya and, from outside the region, the United States, the United Kingdom and France. The contrast between the growth and modernisation of other navies and the contraction and ageing of the South African Navy is highlighted. It is concluded that these developments leave South Africa strategically vulnerable.

In this paper, we consider the problem of performing quantitative Bayesian inference and model averaging based on a set of qualitative statements about relationships. Statements are transformed into parameter constraints which are imposed onto a set of Bayesian networks. Recurrent relationship structures are resolved by unfolding in time to Dynamic Bayesian networks. The approach enables probabilistic inference by model averaging, i.e. it allows to predict probabilistic quantities from a set of qualitative constraints without probability assignment on the model parameters. Model averaging is performed by Monte Carlo integration techniques. The method is applied to a problem in a molecular medical context: We show how the rate of breast cancer metastasis formation can be predicted based solely on a set of qualitative biological statements about the involvement of proteins in metastatic processes.

Growth of aligned carbon nanotubes (CNT) by a secure injection CVD process on large quartz substrates and carbon fiber (CF) cloths has been reported in this study. Adjustments of CVD setup and synthesis parameters have been achieved to control the CNT growth in terms of homogeneous covering of the substrates and to tailor the length of CNT. Two parameters have been optimized such as the precursor feeding rate per reactor surface unit and the carrier gas flow rate.

In this article, we study the effects on derivative pricing arising from price impacts by large traders. When a large trader issues a derivative and (partially) hedges his risk by trading in the underlying, he influences both his hedge portfolio and the derivative's payoff. In a Black–Scholes model with a price impact on the drift, we analyze the resulting trade-off by explicitly solving the utility maximization problem of a large investor endowed with an illiquid contingent claim. We find several interesting phenomena which cannot occur in frictionless markets. First, the indifference price is a convex function of the contingent claim – and not concave as in frictionless markets – implying that for any claim the buyer's indifference price is larger than the seller's indifference price. Second, the seller's indifference prices of large positions in derivatives are smaller than the Black–Scholes replication costs. Therefore, a large trader might have an incentive to issue options if they are traded at Black–Scholes prices. Furthermore, he hedges option positions only partly if he has a negative price impact and thus exploits his ability to manipulate the option's payoff. For a positive price impact he overhedges the option position leading to an extra profit from the stock position exceeding a perfect hedge. Finally, we also study a model where the large shareholder has a price impact on both drift and volatility.

Over the past two years, the Engineering Measurements Lab has attempted to increase the breadth and depth of course material introduced to students to allow them to design and perform successful experimental tests. Over that time, the following structural changes have been made to this course: (i) a single lecture contact hour per week was added, (ii) lab contact hours focus more on practical aspects of each lab, and (iii) the number of experiments run in the course has increased from four to seven. To reflect these changes, the course has grown from one credit to two credits. Material for each lab was delivered in a two-week cycle with a one-hour lecture and two-hour lab period every week. Each lab had one dedicated lecture and additional lectures were added to further emphasize broader topics including data acquisition, measurement uncertainty, and statistical analysis. In addition to the updated course content, the Toyota A3 report format has been adopted for all labs to expose students to a wider variety of tools for technical communication and to foster a spirit of creative and innovative problem solving. In keeping with the iterative nature of these reports, the general process for each lab involves multiple events with feedback from peers and instructors. During the week “A” lab period, students are introduced to the lab facility and perform an ungraded activity where they manually perform relevant calculations using a small subset of previously recorded data. They are then presented with a full set of previous data so they can perform relevant calculations and plot pertinent information. This prelab data exercise is submitted before the week “B” lab period. During the week “B” lab period, students run the laboratory to generate their own data set. A draft A3 report is then submitted prior to the following week “A” lab period. Students peer-review the draft A3 reports in lab before they perform the manual activity for the next laboratory. Final A3 drafts are due at 11:59 pm the following day. Lab topics for this course include characterization of (i) vortex tubes, (ii) vapor compression refrigeration, (iii) centrifugal pumps, and (iv) frictional pipe losses. New labs have been developed for this course examining (v) error propagation in measurement of complex geometries, (vi) measuring Poiseuille flow velocity profiles, and (vii) thermocouple calibration. This work will describe the changes made to this course over the past two years and discuss their suitability based on effectiveness and student satisfaction. Plans for future development of the course will also be discussed. Introduction A recent ABET self-study study report at the Rochester Institute of Technology focused on changes to the mechanical engineering curriculum during semester conversion identified Engineering Measurements Lab as an opportunity to develop a better understanding of (i) measurement techniques, (ii) experimental design, (iii) data acquisition, and (iv) sensors. These topics were formally covered in courses that were discontinued during conversion from quarters to semesters in fall of 2013. As part of that process, Thermo-Fluids Lab I has evolved into Engineering Measurements Lab. The goal of this change was to have students focus more on developing proper measurement techniques and experimental design. The initial development of the Engineering Measurements Lab was described by the authors. This course consisted of four guided labs and an independent study. The guided labs were similar to those administered in the past, but Toyota A3 report format was adopted in an effort to improve technical communication skills. This report format relies heavily on the development of high quality visual aids that can communicate the findings of an investigation on a single-sided A3 paper (11.7” x 16.5”). These reports force students to develop their ability to create information dense figures, which will also enhance their capacity to write traditional technical reports. Technical communication skills are often cited as one of the most desirable hiring criteria for graduates of engineering programs in the United States. In initial offerings of Engineering Measurements Lab, students favored the A3 format to traditional lab reports but instructors felt that students could focus on aesthetic appeal at the expense of their technical understanding. Technical pre-lab activities were introduced in most labs to strengthen the technical rigor of the course. In addition to a shift in focus, Engineering Measurements Lab has attempted to increase the breadth and depth of course material introduced to students so that they might better design and perform empirical tests. As such, the course has increased from one academic credits to two. This increased academic rigor is seen in the following changed in the course: (i) a single lecture contact hour per week was added, (ii) lab contact hours focus more on practical aspects of each lab, and (iii) the number of experiments run in the course has increased from four to seven. A lecture discussing theoretical and practical considerations for each experiment was developed and delivered before students performed the lab. Other lectures covering general experimental practices (i.e. propagation of uncertainty) or content related to labs that are in development (i.e. introduction to data acquisition systems) were delivered throughout the term. As in the previous work, student feedback was collected at the conclusion of the semester (survey provided in Appendix A). Results from this survey are presented throughout this document. These survey results constitute all of the assessment data that are available at this time for the changes that have been made to the course. Specific assessment activities will eventually be incorporated to gauge the efficacy of the new components, consistent with general ABET assessment processes that are in place for the curriculum as a whole. However, because of the factors that originally motivated the changes to the course, it is certain that modifications will remain in some form or another, fine-tuned by whatever feedback is received by any formal assessments. The purpose of this discussion at this time is to outline what has been changed, and to present preliminary results. New Labs In this course, students performed a total of seven guided experiments. Four of these experiments were previously developed and have been run in this course for more than 10 years. A detailed description of these labs can be found in the previous work. Three new experiments were developed specifically for this academic year: (1) Volume calculation, (2) Velocity profile in pipes and (3) Thermocouple calibration. Table 1 lists the seven lab experiments and the schedule for last fall semester, highlighting the three new additions. Table 1. Lab Experiments and Schedule for the Semester

Currently, there is less research works on military entity recognition across corpus. Three types of military entity recognition corpus, namely abbreviated, scientific or English name, novel and random, are constructed to improve the construction of sub-scenario datasets, according to the heterogeneous characteristics of military entities in different military data sets, such as military documents, reconnaissance intelligence, simulation training mission conception, military books, military blogs, military reviews and military websites. With respect to the fuzzy boundaries of military heterogeneous entities we improve the entity annotation mechanism for entity with fuzzy boundaries based on related research works. We apply a BERT-BiLSTM-CRF model fusing deep learning and machine learning to recognize military entities, and design multiple types of experiments to verify the practical effects of the model. Experimental results show that the recognition effect of the model keeps improving with the increasing size of the corpus in the multi-data source scenario, with the F-score increasing from 73.56% to 84.53%.

Microsphere biolasers have attracted a great deal of interest due to their potential for biosensing and cell tracking. Here we demonstrate a novel, to the best of our knowledge, microfluidic-based fabrication of nearly monodisperse dye-doped protein microsphere biolasers with a tunable size from 150 to 50 µm. In particular, for an 85 µm-bead, about 70% of the fabricated microspheres have the same size of 85 µm. Under optical pumping, the fabricated microspheres emit whispering gallery mode lasing emission with a lasing threshold of ${{7}}\;\unicode{x00B5} {\rm{J}}\;{{\rm{mm}}^{- 2}}$ and quality ($\!Q$) factor up to 3000. Interestingly, microspheres with the same size exhibit a similar lasing threshold and spectrum. The result indicates a high reproducibility of microsphere biolasers by the microfluidic-based fabrication technique. This Letter provides an effective method for mass production of high-$Q$ factor microsphere biolasers which is a significant step toward real biosensing and medical applications.

Most pregnancy leаd to а successful outcome without complicаtionHowever, many factors can interfere with the normal process of pregnancy and may threat to the health of the mother or the development of the fetus. These fаctors can be detected at the beginning of pregnancy by reviewing the dаnger signs that may indicate complication. Pre-eclаmpsiа (PE) is а multi-system disorder of the mother that affects the fetus because of utero-plаcental insufficiency. In consequence, these children are at risk for intrа-uterine growth restriction and may be delivered premаturely. They may also suffer from the consequences of high rate of operative deliveries and the adverse effects of maternal drugs. These neonаtes may also have а spectrum of hemаtologicаl changes which may add to the existing morbidity in them. This can cause uncontrollаble bleeding and be life-threаtening for both mother and baby. Another complication is Eclаmpsiа (Pre-eclаmpsiа plus seizures) that happens when PE is uncontrolled. This is аssociated with maternal mortality. Fetal and newborn complicаtions of hypertensive disorders of pregnаncy include growth restriction, premаturity, and stillbirth. In addition, there is evidence that the intrauterine milieu in а hypertensive pregnаncy may, by mechanisms related to the fаilure of the fetus to exercise full growth potentiаl, confer increased risk of cаrdiovаsculаr events in adult life.

Unlike truth commissions elsewhere, the South African Truth and Reconciliation Commission (TRC) investigated the role of business in its exploration of the past. In so doing, it moved beyond its brief to examine gross human rights violations by individuals acting with political motives. The TRC found that some sectors of business were more involved with the apartheid regime than others, but that most businesses were culpable by virtue of having benefited from operating in a racially structured environment. Whereas apartheid agents were granted amnesty in return for full disclosure and encouraged to seek reconciliation with their victims, the TRC proposed that wealth taxes be considered as appropriate restitution with regard to business. The TRC thus shifted from a focus on individual perpetrators, to a systematic analysis that equated any profitable activity with prospering under apartheid and drew a link between benefiting from the system and moral culpability for it. This systemic approach directed attention away from those whose involvement with the apartheid regime was of graver moral concern than that of others, and took the heat off wealthy individuals who, by virtue of personal contacts and financial muscle, might have been able to effect change faster had iey acted more decisively. ONE OF THE PROBLEMS that confronted the negotiating parties during South Africa's transition to democracy was how to deal with gross human rights violations under apartheid. This was resolved through an agreement to set up a Truth and Reconciliation Commission (TRC) with the power to grant amnesty to perpetrators of gross human rights violations that occurred between 1 March 1960 and 31 May 1994. In terms of the Act which established the TRC (Act no.34 of 1995), a gross human rights violation entailed the killing, abduction, torture or severe ill-treatment of any person (or conspiracy, incitement or instigation to commit such acts) by people acting with a political motive. Other (lesser) human rights violations, such as discrimination and dispossession, were thus excluded from this strict definition. According to Mahmood Mamdani, this narrow mandate resulted in the TRC producing a 'diminished truth' which focused on narrow categories of The author teaches in the School of Economics, University of Cape Town, and wishes to thank Jeremy Seekings for comments on earlier drafts.

AbstractIn recent years, resilience has received the most attention from various parties. The concept which was initially better known in the ecological field, then also developed in the social field, so that the term social resilience is known. Some social scientists have made a definition of social resilience, but it still needs to be criticized from the standpoint of sociology. This paper aims to discuss the concept of social resilience from the perspective of sociology. Furthermore, the second purpose of this paper is to describe the resilience of small fishing communities in a village in Banyuwangi as an example application of the social resilience concept discussed. The method used to achieve the first objective is by reviewing relevant writings to discuss social resilience from a sociological point of view. Meanwhile, the second objective was discussed using data from the results of the field study, which was conducted using a qualitative approach. According to the author, social resilience can be defined as the ability of a social system to maintain its social integrity or integration, when and / or after being interrupted, both from within and from outside. Furthermore, at the empirical level, this study shows that the small fishing community in Lampon, Banyuwangi has a high social resilience, which is shown by remaining intact this community despite and has been experiencing various pressures and threats, including climate change and tsunami disasters.
Dalam beberapa tahun belakangan ini, resiliensi mendapat perhatian yang besar dari berbagai pihak. Konsep yang awalnya lebih dikenal di bidang ekologi ini, kemudian juga berkembang juga di bidang sosial, sehingga dikenal istilah resiliensi sosial. Beberapa ilmuwan sosial telah membuat definisi resilensi social, namun terasa masih perlu dikritisi dari sudut pandang sosiologi. Tulisan ini bertujuan untuk membahas konsep resiliensi sosial tersebut dari perspektif sosiologi. Selanjutnya, tujuan yang kedua dari tulisan ini adalah untuk mendeskripsikan resiliensi komunitas nelayan kecil di satu desa di Banyuwangi sebagai contoh aplikasi dari konsep resiliensi sosial yang telah dibahas. Metode yang digunakan untuk mencapai tujuan pertama adalah dengan me-review tulisan yang relevan untuk membahas tentang resiliensi sosial ditinjau dari sudut pandang sosiologi. Sementara itu, tujuan kedua dibahas dengan menggunakan data hasil studi lapang, yang dilakukan dengan pendekatan kualitatif. Menurut penulis, resiliensi sosial dapat didefinisikan sebagai kemampuan suatu sistem sosial untuk mempertahankan keutuhan atau integrasi sosialnya, pada saat dan/atau setelah mendapat gangguan, baik dari dalam maupun dari luar. Selanjutnya, pada tataran empiris, penelitian ini menunjukkan bahwa komunitas nelayan kecil di Lampon, Banyuwangi memiliki resiliensi sosial yang tinggi, yang ditunjukkan dengan tetap utuhnya komunitas ini sekalipun telah dan sedang mengalami berbagai tekanan dan ancaman, termasuk perubahan iklim dan bencana tsunami.

The need for graduates from master's programs in computer science and related areas is well recognized [19, 20]. Indeed, some companies have a policy of extensively utilizing master's programs at universities for the continuing education of their employees. The Graduate Study Program of Bell Laboratories is well known. At Honeywell Information Systems it has been found that support of continuing studies at the master's level helps in hiring and retaining personnel, and is beneficial to the dissemination of new technology through the organization [29]. It has been demonstrated that programmers acquire new knowledge primarily from other programmers [17]; periodic influx into an organization of graduates of programs of advanced study is therefore essential if the organization is to retain technical soundness.
Universities have responded to this need, but in a rather haphazard manner, with the result that we have today a variety of programs, some of which have very little to do with computer science. Some of the programs are no more than, to use Smoliar's [41] words, “undergraduate programs for grown-ups.” Others are viewed as a first stage in the preparation for research careers of narrow specialization. Late in 1972 Terry Walker [45] conducted a poll of master's degree granting departments. The four primary objectives of a master's program given by the 93 respondents were: prepare a person for a job designing computer software systems, prepare a person for a job as a systems analyst, prepare a person to pursue a doctoral degree in computer science, prepare a person for a job as a scientific programmer. Today one would add a fifth objective: prepare a person for teaching computer science at the junior college level. There is clearly a need to reconcile these different objectives with a unified view of computer science.

Abstract The aim of the study was to assess the effect of delayed photo-initiation on the polymerization contraction stress (PCS) and degree of conversion (DC) of a dual-cure resin-luting agent. Thirty-five disk (6 mm × 1 mm) samples (n = 10 each group) of dual cure resin luting agent for PCS assessment were fabricated and polymerized using two illuminated quartz rods. Based on the delay in photo-initiation, 30 disks were divided among six groups [group A-0 min (min) delay, group B-2 min, group C-4 min, group D-6 min, group E-8 min and group F-10 min]. A non-photoinitiated group (group G – chemical cure – n = 5) was included as control. The PCS for all specimens was assessed using a Tensometer. For DC evaluation thirty-five specimens were divided into seven groups with delays in photo-initiation (group H-0 min, group I-2 min, group J-4 min, group K-6 min, group L-8 min and group M-10 min, group N-chemical cure). DC was assessed using attenuated total reflectance spectroscopic technique. Statistical comparison among groups was performed using analysis of variance (α = 0.05). The maximum and minimum PCS and DC values with delayed photo-initiation was observed in group-C (3.34 MPa) & group-F (2.44 MPa); and group-M (0.78 MPa) and group-H (0.55 MPa) respectively. Chemically cured samples showed the least PCS (group-G, 1.94) and DC (group-N, 0.53) values in their respective categories. PCS significantly decreased with delayed photo-initiation. A significant increase in DC was noticed when photo-initiation was delayed in the dual cure resin luting agent.

A new formula that represents both ascending and descending portions of uniaxial compressional stress-strain relation is suggested. This formula consists of two parameters, one governing the steepness of ascending portion and the other controlling the steepness of descending portion. For all possible variations of the parameters, the suggested formula implicitly satisfies the basic properties of a complete stress-strain relation that the stress ascends, reaches its peak value, and then descends, as the strain increases. Expressing the parameters in term of concrete strength, the suggested formula automatically satisfies the behavior of concrete under uniaxial compression that the descending portion becomes steeper as concrete strength is higher. Using the suggested formula, the entire range of strength-stress relation can be favorably determined upon comparing to available test data.

Glucocorticoid hormones increase the activity of cytosolic aspartate aminotransferase (cAspAT) in the Fao rat hepatoma cell line. Maximal increase (6-10-fold) was observed 48 h following the addition of the glucocorticoid agonist dexamethasone at a concentration of 0.1 microM. The effect of dexamethasone was specific since it was not mimicked by sex steroids and was inhibited by the glucocorticoid antagonist RU 486. Insulin (0.1 microM) inhibited by more than 50% the induction of cAspAT by glucocorticoids. The cAMP analog, 8-bromoadenosine 3',5'-monophosphate (Br8cAMP, 0.5 mM), potentiated the effect of dexamethasone (2-3-fold) and partially relieved the inhibitory effect of insulin on the induction by dexamethasone. Both insulin and Br8-cAMP had no significant effect on basal activity. The mitochondrial isoenzyme was insensitive to the various hormonal treatments. Northern blot analysis revealed the presence of two major (2.1-kb and 1.8-kb) and one minor (4-kb) mRNA species hybridizing with a rat cAspAT probe. The regulation of these mRNAs by glucocorticoids, insulin and cAMP correlated with the variation of the cAspAT activity, suggesting that these hormones act at the pretranslational level. We compared the regulation of cAspAT mRNAs with those of tyrosine aminotransferase mRNA. Both were similarly increased by dexamethasone but the latter was also increased by cAMP even in the absence of the glucocorticoid agonist. In addition, the increase in tyrosine aminotransferase mRNA was inhibited by cycloheximide whereas the increase in cAspAT mRNAs was not. These results show that there are significant differences in the regulation of cAspAT and tyrosine aminotransferase by glucocorticoids and other hormones, although both enzymes probably contribute to the same metabolic pathway.

Cloud storage for information sharing is likely indispensable to the future national defence library in China e.g., for searching national defence patent documents, while security risks need to be maximally avoided using data encryption. Patent keywords are the high-level summary of the patent document, and it is significant in practice to efficiently extract and search the key words in the patent documents. Due to the particularity of Chinese keywords, most existing algorithms in English language environment become ineffective in Chinese scenarios. For extracting the keywords from patent documents, the manual keyword extraction is inappropriate when the amount of files is large. An improved method based on the term frequency-inverse document frequency (TF-IDF) is proposed to auto-extract the keywords in the patent literature. The extracted keyword sets also help to accelerate the keyword search by linking finite keywords with a large amount of documents. Fuzzy keyword search is introduced to further increase the search efficiency in the cloud computing scenarios compared to exact keyword search methods. Based on the Chinese Pinyin similarity, a Pinyin-Gram-based algorithm is proposed for fuzzy search in encrypted Chinese environment, and a keyword trapdoor search index structure based on the n-ary tree is designed. Both the search efficiency and accuracy of the proposed scheme are verified through computer experiments.

Blinding (or masking) is the process used in experimental research by which study participants, persons caring for the participants, persons providing the intervention, data collectors and data analysts are kept unaware of group assignment (control vs intervention). Blinding aims to reduce the risk of bias that can be caused by an awareness of group assignment. With blinding, outcomes can be attributed to the intervention itself and not influenced by behaviour or assessment of outcomes that can result purely from knowledge of group allocation.
Lack of blinding in randomised controlled trials (RCTs) has been shown to be associated with more exaggerated estimated intervention effects, by 9% on average.1 Studies with subjective outcomes are more likely to show these exaggerated estimates.2 In a systematic review of 250 RCTs, researchers observed a significant difference in the size of the estimated treatment effect between trials that reported ‘double-blinding’ compared with those that did not (p=0.01), with an overall OR 17% larger in studies that did not report blinding.3 In addition, studies are often simply described as ‘blind’ or ‘double-blind’ and do not specify who was blinded,4 which means blinding of one …

No‐till (NT) farming can restore the soil organic carbon (SOC) pool of agricultural soils, but the SOC pool size and retention rate can vary with soil type and duration of NT. Therefore, the objectives of this study were to determine the effects of NT and soil drainage characteristics on SOC accumulation across a series of NT fields on Alfisols in Ohio, USA. Sites under NT for 9 (NT9), 13 (NT13), 36 (NT36), 48 (NT48) and 49 (NT49) years were selected for the study. Soil was somewhat poorly drained at the NT48 site but moderately well drained at the other sites. The NT48 and NT49 on‐station sites were under continuous corn (Zea mays), while the other sites were farmers' fields in a corn–soybean (Glycine max) rotation. At each location, the SOC pool (0–30 cm) in the NT field was compared to that of an adjacent plough‐till (PT) and woodlot (WL). At the NT36, NT48 and NT49 sites, the retention rate of corn‐derived C was determined using stable C isotope (13C) techniques. In the 0‐ to 10‐cm soil layer, SOC concentration was significantly larger under NT than PT, but a tillage effect was rarely detected below that depth. Across sites, the SOC pool in that layer averaged 36.4, 20 and 40.8 Mg C/ha at the NT, PT and WL sites, respectively. For the 0‐ to 30‐cm layer, the SOC pool for NT (83.4 Mg C/ha) was still 57% greater than under PT. However, there was no consistent trend in the SOC pool with NT duration probably due to the legacy of past management practices and SOC content differences that may have existed among the study sites prior to their conversion to NT. The retention rate of corn‐derived C was 524, 263 and 203 kg C/ha/yr at the NT36, NT48 and NT49 sites. In contrast, the retention rate of corn‐C under PT averaged 25 and 153 kg C/ha/yr at the NT49 (moderately well‐drained) and NT48 (somewhat poorly drained) sites, respectively. The conversion from PT to NT resulted in greater retention of corn‐derived C. Thus, adoption of NT would be beneficial to SOC sequestration in agricultural soils of the region.

Massive multiple-input multiple-output (MIMO) techniques have been proposed as a solution to satisfy many requirements of next generation cellular systems. One downside of massive MIMO is the increased complexity of computing the precoding, especially since the relatively “antenna-efficient” regularized zero-forcing (RZF) is preferred to simple maximum ratio transmission. We develop in this paper a new class of precoders for single-cell massive MIMO systems. It is based on truncated polynomial expansion (TPE) and mimics the advantages of RZF, while offering reduced and scalable computational complexity that can be implemented in a convenient parallel fashion. Using random matrix theory we provide a closed-form expression of the signal-to-interference-and-noise ratio under TPE precoding and compare it to previous works on RZF. Furthermore, the sum rate maximizing polynomial coefficients in TPE precoding are calculated. By simulation, we find that to maintain a fixed peruser rate loss as compared to RZF, the polynomial degree does not need to scale with the system, but it should be increased with the quality of the channel knowledge and signal-to-noise ratio.

A numerical model for the load transfer mechanism in mooring anchor systems, commonly used in offshore petroleum industry, is presented in this work. Special attention is paid to the mechanical modelling of the contact interaction of the two medium components, namely the soil and the embedded mooring line. Resorting to the “embedded element concept” [1], a mixed 3D-1D finite element formulation is developed in the context of finite elastoplasticity. A Tresca-like model is used to describe the nonlinear material behaviour of the surrounding soil under undrained conditions, whereas the embedded mooring line regarded as curvilinear bar-like inclusion is assumed to behave elastically with account for geometric nonlinearities. The Mohr-Coulomb model is employed to define the bond-stress and bond-slip relationships at the interface. Nonlinear static and dynamic analyses are performed with a corotational kinematic description in order to include large deformation in the problem [2]. Preliminary results indicate that the main frequencies of the dynamic load applied to the mooring line-soil system are much lower than those of the system itself, thus the overall system may be evaluated disregarding inertial effects. Further simulations based on parametric studies by varying relevant problem parameters are needed to corroborate this result. Moreover, the average load attenuation induced by friction along the soil/mooring line interface for the studied cases is around 25%. Formulation of the interface constitutive behaviour in the context of large strain to address large relative movements between embedded inclusion and surrounding soil is an ongoing task [3]. Parallel implementation of Karena Q. Jimenez, Jorge P. Tamayo, Samir Maghous and Alexandre Braun 2 the finite element model with specific data structure storage and iterative solver is currently addressed to handle large 3D computational models.

This paper describes a snapshot Mueller matrix polarimeter by wavelength polarization coding. This device is aimed at encoding polarization states in the spectral domain through use of a broadband source and high-order retarders. This allows one to measure a full Mueller matrix from a single spectrum whose acquisition time only depends on the detection system aperture. The theoretical fundamentals of this technique are developed prior to validation by experiments. The setup calibration is described as well as optimization and stabilization procedures. Then, it is used to study, by time-resolved Mueller matrix polarimetry, the switching dynamics in a ferroelectric liquid crystal cell.

This article analyses and compares the four elections held between September 1997 and September 1998 in the four 'Visegraď countries (Poland, Hungary, the Czech Republic and Slovakia), all of which led to a change of government. It concentrates on the effect of these elections on the development of party systems, seeking to identify trends across the region. It notes that the key issue was the restructuring of the centre-right. It concludes that party systems remain more unstable than might have been thought and that the process of restructuring is far from over. Czech Sociological Review, 2000, Vol. 8 (No. 1: 93-101)

The application of deep learning techniques to the detection and automated classification of Alzheimer's disease (AD) has recently gained considerable attention. The rapid progress in neuroimaging and sequencing techniques has enabled the generation of large-scale imaging genetic data for AD research. In this study, we developed a deep learning approach, IGnet, for automated AD classification using both magnetic resonance imaging (MRI) data and genetic sequencing data. The proposed approach integrates computer vision (CV) and natural language processing (NLP) techniques, with a deep three-dimensional convolutional network (3D CNN) being used to handle the three-dimensional MRI input and a Transformer encoder being used to manage the genetic sequence input. The proposed approach has been applied to the Alzheimer's Disease Neuroimaging Initiative (ADNI) data set. Using baseline MRI scans and selected single-nucleotide polymorphisms on chromosome 19, it achieved a classification accuracy of 83.78% and an area under the receiver operating characteristic curve (AUC-ROC) of 0.924 with the test set. The results demonstrate the great potential of using multi-disciplinary AI approaches to integrate imaging genetic data for the automated classification of AD.

Detailed mechanistic studies on the ligand hydroxylation reaction mediated by a copper bis(imine) complex are presented. Starting from a structural analysis of the CuI complex and the CuII product with a hydroxylated ligand, the optical absorption and vibrational spectra of starting material and product are analyzed. Kinetic analysis of the ligand hydroxylation reaction shows that O2 binding is the rate-limiting step. The reaction proceeds much faster in methanol than in acetonitrile. Moreover, an inverse kinetic isotope effect (KIE) is evidenced for the reaction in acetonitrile, which is attributed to a sterically congested transition state leading to the peroxo adduct. In methanol, however, no KIE is observed. A DFT analysis of the oxygenation reaction mediated by the micro-eta2:eta2 peroxo core demonstrates that the major barrier after O2 binding corresponds to electrophilic attack on the arene ring. The relevant orbital interaction occurs between the sigma* orbital of the Cu2O2 unit and the HOMO of the ligand. On the basis of the activation energy for the rate-limiting step (18.3 kcal mol(-1)) this reaction is thermally allowed, in agreement with the experimental observation. The calculations also predict the presence of a stable dienone intermediate which, however, escaped experimental detection so far. Reasons for these findings are considered. The implications of the results for the mechanism of tyrosinase are discussed.

Late mortality and pathology were assessed in various mouse strains following total-body irradiation (TBI) and bone marrow transplantation. A, C57BL/6, B6AF1, LP and C3H mice received TBI in two fractions 3 h apart at total doses of between 11 and 15 Gy. They were then transplanted with syngeneic bone marrow cells providing sufficient reconstitution to avoid hemopoietic failure. Long-term survival data revealed both radiation dose- and strain-dependent onset of mortality between 1 and 2 years post-treatment. Renal damage appeared to have contributed to the late mortality in most treatment groups as shown by glomerular lesions, elevated blood urea nitrogen and an accompanying fall in hematocrit. Hemolysis was deduced to be the major cause of anemia, as concluded from results of 51Cr-labeled erythrocyte survival. No decrease in erythropoiesis was evident as seen from spleen and bone marrow 59Fe uptake. These findings are together consistent with the manifestation of a hemolytic uremic syndrome (HUS) with kidney glomeruli representing the principal sites of injury responsible for both renal dysfunction and microangiopathic hemolysis.

Sodium bismuth titanate, (Na 0.5 Bi 0.5 )TiO 3 (NBT), thin films were grown on Pt/Ti/SiO 2 /Si substrates via a sol-gel process. The precursor solution for spin-coating was prepared from bismuth nitrate, sodium acetate, and titanium n-butoxide as starting materials, and acetic acid and methanol as solvents, and pervoskite NBT films with high (111)-orientation have been obtained. The Au/NBT/Pt thin film capacitor showed a hysteresis loop at an applied electric field of 200 kV/cm with remanent polarization (P r ) and coercive electric field (E c ) values of 20.9 μC/cm 2 and 112 kV/cm, respectively. At 100 kHz, the dielectric constant and loss tan 6 of the film were 171 and 0.024, respectively. The leakage current depended on the voltage polarity. When an electrical field ranges from 0 to 167 kV/cm and with the Pt electrode biased negatively, the NBT/Pt interface exhibits a Schottky emission characteristic. The Au/NBT interface forms an ohmic contact. The conduction current when the Au electrode is biased negatively shows space-charge-limited current (SCLC) behavior.

Propagation of the mean waves in a simple cubic crystal with small, random mass defects is studied using the results of a previous paper. The dispersion equations for two‐ and three‐dimensional crystals are analyzed. For uncorrelated mass defects, the effective propagation constants are obtained explicitly in the limits of low frequency and near cut‐off frequency. The mean reflection and transmission coefficients are determined for a plane wave incident in a crystal formed by joining a semi‐infinite perfect crystal to a semi‐infinite defective crystal or by connecting two semi‐infinite perfect crystals to a finite imperfect crystal. We also construct the mean Green's functions for an infinite crystal lattice containing defective masses distributed throughout it or confined to a half‐space.

nothing could be more gratifying or unexpected. A period of about twelve weeks had sufficed to convert the case into a sort of talipes equinus, the wound was soundly closed, and free motion existed at the hip, the end of the femur being locked apparently against the upper rim of the acetabulum. The youth planted the toes and extremity of the sole of the foot with firmness upon the ground, and skipped and hopped about with evident ease and satisfaction. Mr. Morris has some reason to be proud, and may be excused being somewhat didactic, his case having been pronounced by a gentleman, who omits no opportunity of writing in favour of the operation, one "altogether the most satisfactory and interesting of those hitherto recorded." I cannot, however, but feel that, whilst errors of diagnosis as to the position and state of the head of the bone occur, even in able hands, and a doubt exists as to the fit cases in which the operation may be undertaken with propriety, it will be right to exercise the greatest caution, to avoid a too ready and unnecessary resort to the operation, and I am strengthened in such a view by the recent observation of a formidable case of diseased hip, attended with luxation and considerable sero-purulent effusion, where the joint has been tapped several times, and in which the head of the femur now lies quietly upon the dorsum of the ilium, with no other inconvevenience than a shortening of the limb, and some inconsiderable lameness. Lynn, June 19, 1850.

Abstract The Lithuanian comparative suffix -iaũ(s), e.g. OLith. geriaus ‘better’ / Modern Lith. geriaũ, has risen from a postpositive contrastive focus particle -jaũ used in the function of ‘emphatic assertion of identity’ (see Konig 1991). A final consonant /-s/ in -iaũ-s is an etymologically heterogeneous element, appearing optionally in such lexemes as Lith. dial. net-s ‘even’ : net ‘even’ < OLith. ne-te, OLith. taciau-s ‘however, but’ : taciaũ ‘however, but’ < tat ‘this, that’ + -jaũ, OLith. tuojau-s ‘at soon, once’ : tuojaũ < tuo + -jaũ. The primary contrastive function of the suffix -iau-s can be compared to Old Greek -τeρος in such uses as δeξίτeρος ‘right(-hand)’, emphatic non-σκαιός ‘left(-hand)’.

Introduction: In CAGD, B-spline has been used to describe the free-form shapes in miscellaneous occasions and is widely used in product modeling. With the introduction of weight, B-spline can be upgraded as NURBS, so primary analytic surfaces such as spherical and cylindrical surfaces can be represented. The unified expression of free surfaces as well as primary analytic surfaces by NURBS has long become the backbone for CAD software, but there are still the following drawbacks in existing systems: (1) a single patch cannot express the complex model; (2) it is difficult to obtain watertight geometries in surface merging; (3) for the limitation of the rectangular grid, a large number of superfluous control points will be introduced during local refinement. To overcome these drawbacks, T-spline was proposed by Sederberg et al., of which the T-junction breaks through the limitation of the control points’ rectangular topology, so (2) and (3) of the above drawbacks are annihilated. By introducing extraordinary points into T-spline, with which the T-spline is called as unstructured T-spline, (1) of the above drawbacks is also solved, But unstructured T-spline results in some problems: (1) only

Sleep and emotions are closely associated; however, the methodological challenges in the examination of sleep and the processes of emotion regulation in children and adolescents have not been investigated so far. Additionally, there is the demand to identify the levels of emotion regulating processes in which problematic or restricted sleep causes effect. Experimental sleep deprivation as well as prevalent sleep problems have been found to have negative influence on mental health and regulating functions. This review focuses first on the methodological protocols of the included studies. Subsequently, the results are summarized in the context of a multilevel model of emotion regulation. Thereafter, suggestions for future directions are given. Sleep problems and sleep deprivation are associated with a decrease of functional emotion regulating behavior and impaired emotion generation, and prolonged sleep enhances better mood and affect states, positive emotion expression, and faster sensory processing in response to emotional stimuli. This literature review highlights the limitations in current research, focusing on types of measurements, task characteristics, and data analysis. At the conclusion, suggestions are given for the future research direction in the field of sleep and emotion regulation in children and adolescents.

A requirement for cell homeostasis is the correct functioning of chaperones, which inhibit the aggregation of other proteins in the cell. The chaperone SurA, present in gram‐negative bacteria, prevents the aggregation of outer membrane porins as they traverse the aqueous periplasm. Disruption of SurA activity renders the bacterial cell more sensitive to agents that would normally be kept out by outer membrane porins. Here we describe an in vitro screen to test potential small molecule inhibitors of SurA that could be used to decrease the virulence of bacterial cells. Using fluorescence anisotropy, we conduct competitive binding assays using fluorescently‐tagged peptides that bind SurA with high affinity and small molecules discovered using in silico screening.

KinÊtre allows novice users to scan arbitrary physical objects and bring them to life in seconds. The fully interactive system allows diverse static meshes to be animated using the entire human body. Traditionally, the process of mesh animation is laborious and requires domain expertise, with rigging specified manually by an artist when designing the character. KinÊtre makes creating animations a more playful activity, conducted by novice users interactively "at runtime". This paper describes the KinÊtre system in full, highlighting key technical contributions and demonstrating many examples of users animating meshes of varying shapes and sizes. These include non-humanoid meshes and incomplete surfaces produced by 3D scanning - two challenging scenarios for existing mesh animation systems. Rather than targeting professional CG animators, KinÊtre is intended to bring mesh animation to a new audience of novice users. We demonstrate potential uses of our system for interactive storytelling and new forms of physical gaming.

When an agreement controller contains conflicting semantic and formal features, the predicates that agree with it can differ with respect to the type of features they reflect. With the second person pronoun used for politely addressing a single referent, finite verbs always agree in (formal) plural number, while participles in some languages may or must agree in (natural) singular number and gender. Building on the claims from the previous literature that the honorific pronoun formally encodes both the grammatical features (plural number and person) and the natural gender and singular number, the analysis proposed in this paper derives the variation in predicate agreement by combining the formal tools of feature geometries, separate probing and variation in the ordering of Agree operations. The main claim advanced by the paper is that predicates differ with respect to the φ-features they probe for, and the order in which this probing applies.

The paper considers the results of modelling acoustic emission signals that form under variations in the rotational speed of a friction pair made of a composite material. It is found that the energy accumulation in acoustic emission signals that form relative to time takes place in accordance with linear law under normal wear of a friction pair. If the rotational speed of a friction pair increases, the rates of accumulated average energy and accumulated total energy of the acoustic emission signals that form also grow. The resulting acoustic emission signals have both accumulated average energy and accumulated total energy. A comparison of these two types of energy is conducted. It is shown that the application of data averaging reduces the rate of the accumulated energy of the acoustic emission signals that form.

The chloroplast-targeted ferredoxin-NADP+ oxidoreductase (LFNR) is a hydrophilic flavin protein located at the end of the photosynthesis electron delivery chain in higher plants. It’s a hub for linking photosynthesis electronic transportation with chloroplast redox metabolism. In order to explore the relationship between LFNR gene and yellowing of ‘Huangjinya’controlled by light, we took separately one bud two leaves of ‘Huangjinya’ ‘Shuchazao’(CK) as the material to clone CsLFNR gene and then we obtained the sequence with a similarity of 100%, named CsLFNR1.1 (GenBank accession no. MT311318). Throw bioinformatics analysis, we know its cDNA gene length is 1 095 bp, coding 364 amino acids, The protein molecular weight is 40.623KDa, the theoretical isoelectric point is 8.86.CsLFNR1.1 is a alkaline protein without transmembrane structure and signal peptide, it has a chloroplast transport peptide (cTP), the secondary structure contains 23.35% alpha helix, 5.49% beta-corner, 28.85% extension chain and 42.31% irregular curling, It locates in the chloroplast. Through the Nucleotide BLAST, Protein BLAST and DNAMAN software, we found that CsLFNR1.1 and its translated amino acid sequences had 4 bases and 3 amino acid differences with NCBI ‘Shuchazao’ Gene CsLFNR1 (XM_028233617.1) and Protein (XP_028089418.1), the similarity reached 99.63% and 99.18%. CsLFNR1.1 and CsLFNR1 have small differences in the physical and chemical properties and secondary structure, the tertiary structure prediction template of them is consistent. In addition, they have the same conserved domain and active site. We took different shade ‘Huangjinya’ blades as the material for qRT-PCR, the result showed that the expression of CsLFNR1.1 gene response to the light intensity, its expression increased with the increase of light intensity. This study provides a theoretical basis and scientific basis for further exploring the role of CsLFNR1.1 gene in the light regulation process of the new shoots and leaves of ‘Huangjinya’.

First-principles phase diagrams of bismuth-stabilized GaAs- and InP(100) surfaces demonstrate for the first time the presence of anomalous (2x1) reconstructions, which disobey the common electron counting principle. Combining these theoretical results with our scanning-tunneling-microscopy and photoemission measurements, we identify novel (2x1) surface structures, which are composed of symmetric Bi-Bi and asymmetric mixed Bi-As and Bi-P dimers, and find that they are stabilized by stress relief and pseudogap formation.

BACKGROUND/AIMS
Difficulties with bathing are frequent among older people and are associated with an increasing need for societal support. As loss of independence has a negative impact on health and wellbeing, it is important to study interventions that can provide the required support for people to be able to remain independent. Occupational therapy interventions can improve clients' abilities enabling them to bathe themselves, thus reducing the need for other, more long-term societal support from, e.g. a home help. In this study, two groups of elderly people with difficulties in bathing were compared; the clients in the intervention group were engaged in occupational therapy.
METHODS
A quasi-experimental non-equivalent control group design was used, in which participants with reported difficulties in bathing were recruited consecutively from two municipalities. The clients in the intervention group routinely received occupational therapy, whereas clients in the control group received assistance from a home help for bathing. Activities of daily living, quality of life and home-help allocation were assessed at the baseline and after 15 weeks.
RESULTS
Clients in the intervention group received less than three home visits on average, with majority of interventions consisting of graded activity and the use of an encouraging approach. Seventy per cent of the interventions were adaptive. Activities of daily living and quality of life of both groups improved, but the differences of being allocated a home help were significant.
CONCLUSION
Occupational therapy interventions seem beneficial in terms of supporting older people in becoming independent of home help in bathing but the results must be interpreted with caution as there were differences at baseline between the groups.

By modulating important properties of eukaryotic cells, many bacterial protein toxins highjack host signalling pathways to create a suitable niche for the pathogen to colonize and persist. Helicobacter pylori VacA is paradigm of pore-forming toxins which contributes to the pathogenesis of peptic ulceration. Several cellular receptors have been described for VacA, which exert different effects on epithelial and immune cells. The crystal structure of VacA p55 subunit might be important for elucidating details of receptor interaction and pore formation. Here we discuss the multiple signalling activities of this important toxin and the molecular crosstalk between VacA and other virulence factors.

: Japanese firms’ compliance activities have developed and become the norm to a certain extent. However, when we surveyed seven companies in various industries, including two firms that have experienced scandals, through interviews and public documents, we found that these seven firms’ compliance systems were surprisingly similar. This is because the institutionalization of compliance activities among Japanese firms has advanced under the influence of the Japan Business Federation and the Japanese government, and in fact, the mechanism of Dimaggio and Powell’s institutional isomorphism is at work. We believe that this is because the isomorphism in compliance activities that has developed independently of performance or of the ability to prevent scandals.

In 1955, after completing a medical residency, I joined the laboratory of Dr Henry Kunkel at the Rockefeller Institute, New York City. Dr Kunkel’s interest had just changed from hepatic diseases to rheumatic diseases. He wished to explore the causes of two blood reactions that occurred in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) and were used in diagnosis. The laboratory had two critical laboratory techniques available for that purpose. The first was preparative electrophoresis that had been developed by Dr Kunkel and allowed separation and recovery of serum proteins by their electric charge. The second was an ultracentrifuge that had just been purchased and allowed separation and recovery of serum proteins based on their molecular weight. As we discussed the approaches to pursue, Dr Kunkel said to me something like ‘I’ll take RA, you take SLE’. The target in SLE was the LE cell. This cell rarely occurred in vivo but, if drawn blood was allowed to stand for some 30minutes or longer at room temperature, the cells appeared on blood smears. The cell consisted of a polymorphonuclear leucocyte with its nucleus crushed to the side by a large phagocytized inclusion body. Others had shown that the inclusion body stained like nucleic acid and that a globulin serum factor appeared to cause the event. The first step was to characterize the serum factor. On preparative electrophoresis, it moved as a rapidly migrating immunoglobulin and could be isolated from other serum proteins. It also sedimented with the bulk of immunoglobulins with a molecular weight of approximately 150,000 Da. Thus, the serum factor appeared to be an antibody. The next step was to identify the cell reactant, which was probably of nuclear origin. Cell nuclei were isolated, relatively free of cytoplasm. Mostly they were obtained from readily available calf thymocytes but also from human and other species’ cells. Isolated nuclei absorbed the serum factor completely from SLE serum and, with proper treatment, the factor could be eluted from the nuclei. The eluted factor was precipitated specifically by antibody to immunoglobulin, consolidating the evidence that it was an antibody. Further, nuclei from which DNA was removed by deoxyribonuclease were unable to absorb the factor, implicating DNA as at least part of the antigen. Nuclei were then fractionated into insoluble nucleoprotein (chromatin) and soluble nuclear sap. The nucleoprotein consists largely of DNA and histones and is the stuff of chromosomes while the sap contains innumerable nuclear constituents. Insoluble strands of nucleoprotein absorbed the LE cell factor from serum and, when washed and incubated with polymorphonuclear leucocytes, were ingested to form inclusion bodies virtually identical to those of an LE cell. Digestion of the nucleoprotein with deoxyribonuclease removed its ability to react with the serum factor while extraction of histone lessened it. In those days, fluorescent antibodies were becoming available. When LE cells were stained with fluorescent antibody to immunoglobulin, the inclusion bodies fluoresced brilliantly, indicating a coating of immunoglobulin. From these data, we concluded that the LE cell is a product of an antibody reacting with the patient’s own tissue, that is, an autoantibody engaged in an autoimmune reaction. Thus, we were witnessing autoimmunity. The autoantigen in the patient’s tissue was DNA, hitherto unknown as an antigen. Also at that time, autoimmunity was unknown or, more accurately, had not been recognized. Subsequently, it was found that some SLE sera could react with purified double-stranded DNA, with histone alone or with many constituents of the soluble nuclear sap (e.g. the Sm antigen, ribonucleoprotein, the Ro and La antigens). Thus, an array of autoantibodies to different components of the cell nucleus became the hallmark of SLE and SLE became perceived as an autoimmune disease.

espanolPara avanzar en la comprension de la Provincia Geocronologica Rio Negro-Juruena (1,55-1,8 Ga) del Craton Amazonico en el suroriente colombiano se analizaron rocas metamorficas, igneas y meta-sedimentarias aflorantes alrededor del Rio Cuiari en el sur del Departamento de Guainia, zona limitrofe Colombia-Brasil. Con base en observaciones de campo, analisis mineralogicos, geoquimicos y edades LA-ICP-MS U/Pb en circones se identifico en el area un basamento Estateriano (formando aqui el Complejo Mitu) compuesto de granitoides tipo S, principalmente monzograniticos y en menor proporcion cuarzo-monzoniticos a granodioriticos, calcoalcalinos, meta a peraluminosos, con caracteristicas de granitos sin-colisionales a pos-orogenicos con edades U/ Pb de cristalizacion entre 1760 y 1800 Ma. Adicionalmente afloran intrusivos graniticos mas alcalinos de textura porfiritica con fenocristales ovoides de feldespato potasico y una edad de cristalizacion U/Pb en circones de ~1750 Ma (probablemente asociado a la Suite Intrusiva Tiquie definida en Brasil). Sobre este basamento Estateriano fue depositada una secuencia sedimentaria (que pertenece al Grupo Tunui) entre 1750 y 1600 Ma descritas como metarenitas y cuarcitas con turmalina, probablemente como miembro superior del Grupo Tunui que fue afectado por metasomatismo relacionado con la intrusion de un granito porfiritico de dos micas con una edad de cristalizacion entre 1550 y 1600 Ma (asociado a la Suite Intrusiva Rio Icana). Circones heredados con edades del Complejo Mitu ~1780 Ma en este intrusivo sugieren un origen del magma por fusion parcial de material cratonico en presencia de suficiente agua y presion no demasiada alta para una temperatura de fusion relativamente baja que permitieron formar un magma enriquecido en fluidos y elementos incompatibles como Rb y K. Paragneises con edades en circones detriticos mas jovenes entre 1000-1800 Ma, cierran el ciclon geologico precambrico reconocible en esta area de Colombia con un potencial mineralizante y desarrollo tectonico y paleogeografico todavia por determinar en detalleorms the Mitu Complex. EnglishIn order to archive a better understanding of the Rio Negro-Juruena Geochronological Province (1.55-1.8 Ga) of the Amazonian Craton in SE-Colombia, we performed analyses of metamorphic, igneous and metasedimentary rocks outcropping in vicinity of the Cuiari-River in the south of Guainia Department, near the Brazilian border. Based on field observations, mineralogical, geochemical and U/Pb LA-ICP-MS analysis in zircons, we could identify in the study area a Statherian basement which fS-type granitoides, mainly monzogranitic to a lesser amount of quartz-monzodioritic to granodioritic, with calc-alkalic meta to peraluminosos, syncollisional to post orogenic characteristics and with U/Pb crystallization ages between 1760 to 1800 Ma. Additionally, in the study area more alkalic granitic intrusions with ovoidal K-feldspar phenocrysts forming a porphyritic texture outcrop where U/Pb zircon data suggest a crystallization age of ~1750 Ma (probably associated to the Tiquie Intrusion Suite defined in Brazil).Over this Statherian basement, a sedimentary sequence (which may represent the Upper Member of the Tunui Group in Brazil) was deposited some 1750-1600 Ma ago, where metarenites and quartzites were impregnated by tourmalines as a result of metasomatic processes related to the intrusion of a porphyritic two-mica granite crystalized 1550 to 1600 Ma ago (associated with the Rio Icana Intrusive Suite in Brazil). Some ~1780 Ma old inherited zircons from the Mitu Complex in this intrusion suggest a magma origin by partial melting of cratonic cortical material triggered by sufficient water and low pressures for melting point decrease generating a magma enriched in fluids and incompatible elements like Rb and K. Younger paragneisses with detrital zircon ages between 1000 to 1800 Ma close the Precambrian geological cycle identified in this area of Colombia. Its mineralizing potential as well as a tectonic and paleogeographic history still to be deciphered in detail.

Humanized mice reconstituted with human hematopoietic cells have been developed as an experimental animal model for human immunodeficiency virus type 1 (HIV-1) infection. Myeloablative irradiation is usually performed to augment the engraftment of donor hematopoietic stem cells (HSCs) in recipient mice; however, some mouse strains are susceptible to irradiation, making longitudinal analysis difficult. We previously attempted to construct humanized NOD/SCID/JAK3null (hNOJ) mice, which were not irradiated prior to human HSC transplantation. We found that, over time, many of the reconstituted CD4+ T cells expanded with an activated effector memory phenotype. Therefore, the present study used hNOJ mice that were irradiated (hNOJ (IR+)) or not (hNOJ (IR−)) prior to human HSC transplantation to examine whether the development and cellularity of the reconstituted CD4+ T cells were influenced by the degree of chimerism, and whether they affected HIV-1 infectivity. Indeed, hNOJ (IR+) mice showed a greater degree of chimerism than hNOJ (IR−) mice. However, the conversion of CD4+ T cells to an activated effector memory phenotype, with a high percentage of cells showing Ki-67 expression, occurred in both hNOJ (IR+) and hNOJ (IR−) mice, probably as a result of lymphopenia-induced homeostatic expansion. Furthermore, when hNOJ (IR+) and hNOJ (IR−) mice, which were selected as naïve- and memory CD4+ T cell subset-rich groups, respectively, were infected with CCR5-tropic HIV-1 in vivo, virus replication (as assessed by the plasma viral load) was delayed; however, the titer subsequently reached a 1-log higher level in memory-rich hNOJ (IR−) mice than in naïve-rich hNOJ (IR+) mice, indicating that virus infectivity in hNOJ mice was affected by the different status of the reconstituted CD4+ T cells. Therefore, the hNOJ mouse model should be used selectively, i.e., according to the specific experimental objectives, to gain an appropriate understanding of HIV-1 infection/pathogenesis.

ABSTRACT In torque generation by the bacterial flagellar motor, it has been suggested that electrostatic interactions between charged residues of MotA and FliG at the rotor-stator interface are important. However, the actual role(s) of those charged residues has not yet been clarified. In this study, we systematically made mutants of Vibrio alginolyticus whose charged residues of PomA (MotA homologue) and FliG were replaced by uncharged or charge-reversed residues and characterized the motilities of those mutants. We found that the members of a group of charged residues, 7 in PomA and 6 in FliG, collectively participate in torque generation of the Na+-driven flagellar motor in Vibrio. An additional specific interaction between PomA-E97 and FliG-K284 is critical for proper performance of the Vibrio motor. Our results also reveal that more charged residues are involved in the PomA-FliG interactions in the Vibrio Na+-driven motor than in the MotA-FliG interactions in the H+-driven one. This suggests that a larger number of conserved charged residues at the PomA-FliG interface contributes to the robustness of the Vibrio motor against mutations. The interaction surfaces of the stator and rotor of the Na+-driven motor seem to be more complex than those previously proposed in the H+-driven motor.

Due to the increasing frequency of wildfires in recent years, there is a strong need for developing mitigation strategies to manage the impact of smoke exposure of vines and occurrence of ‘smoke taint’ in wine. One plausible approach would be to prevent or inhibit the uptake of volatile phenols from smoke into grape berries in the vineyard. In this study we describe a model system we developed for evaluating under controlled conditions the effectiveness of a range of surface coatings (including existing horticultural sprays) for reducing/preventing the uptake of volatile phenols and their subsequent conversion to phenolic glycosides. Grapes were coated with the materials to be tested and then exposed to gaseous phenols, via evaporation from an aqueous solution, in a semi-closed glass container. Analysis of volatile phenols and their glycosidic grape metabolites demonstrated that the treatments typically did not provide any significant protection; in fact, some resulted in higher concentrations of these compounds in the grapes. The highest concentrations of volatile phenols and their glycosides were observed after application of oily, hydrophobic materials, suggesting that these materials may enhance the adsorption or transfer of volatile phenols into grape berries. Therefore, it is important to consider the types of sprays that are being applied in the vineyard before and during smoke events to prevent the potential of exacerbating the uptake of smoke compounds by grape berries.

Background: National clinical guidelines have been developed internationally to reduce variations in clinical practices and promote the quality of palliative care. In The Netherlands, there is considerable variability in the organisation and care processes of inpatient palliative care, with three types of hospices – Volunteer-Driven Hospices (VDH), Stand-Alone Hospices (SAH), and nursing home Hospice Units (HU). Aim: This study aims to examine clinical practices in palliative care through different hospice types and identify variations in care. Methods: Retrospective cohort study utilising clinical documentation review, including patients who received inpatient palliative care at 51 different hospices and died in 2017 or 2018. Care provision for each patient for the management of pain, delirium and palliative sedation were analysed according to the Dutch national guidelines. Results: 412 patients were included: 112 patients who received treatment for pain, 53 for delirium, and 116 patients underwent palliative sedation therapy. Care was provided in accordance with guidelines for pain in 32%, 61% and 47% (P = .047), delirium in 29%, 78% and 79% (P = .0016), and palliative sedation in 35%, 63% and 42% (P = .067) of patients who received care in VDHs, SAHs and HUs respectively. When all clinical practices were considered, patient care was conducted according to the guidelines for 33% of patients in VDHs, 65% in SAHs, and 50% in HUs (P < .001). Conclusions: The data demonstrate that care practices are not standardised throughout Dutch hospices and exhibit significant variations between type of hospice.

UK compliance with its international obligations in the area of bribery and corruption is in question. Recent domestic and international developments have brought this issue to the fore. This article addresses UK compliance. In doing so it highlights the multi-faceted nature of the obligations upon the UK and its wide-ranging responses. It is concluded that the UK is in general compliant with the particulars of international law but perhaps not with its spirit.

The kinetics of axial water substitution by azoles (pyrazole and 1,2,4-triazole) in three different cobaloximes, viz.trans-[Co(Hdmg)(2)(R)H(2)O] where Hdmg = dimethylglyoximate, R = PhCH(2), Et and CF(3)CH(2), were studied as a function of azole concentration, temperature and pressure in aqueous solution. The second order rate constants for the substitution of water in trans-[Co(Hdmg)(2)(R)H(2)O] for R = Et at pH 6.0, 25 degrees C and I= 0.1 M (NaClO(4)), were found to be 1309 and 1200 M(-1) s(-1) for pyrazole (Pz) and 1,2,4-triazole (Tz), respectively, and those obtained for R = PhCH(2) were found to be 755 and 691 M(-1) s(-1), respectively. The second order rate constants in the case of R = CF(3)CH(2) were found to be 0.358 and 0.348 M(-1) s(-1) for Pz and Tz, respectively. The relative order of reactivity for the different alkyls being Et > PhCH(2) > CF(3)CH(2). The activation parameters (DeltaH([not equal]), DeltaS([not equal]) and DeltaV([not equal])) obtained for these reactions were found to be in the range of 65-87 kJ mol(-1), 24-47 J mol(-1) K(-1) and 2.5-7.7 cm(3) mol(-1), respectively. These data suggest that an I(d) substitution mechanism operates where the azoles participate in the transition state.

Ochratoxin A (OTA) is a naturally occurring contaminant of cereals, pigmeat, and other foods and is a known genotoxic in animals. It is a nephrotoxin and a carcinogen associated with Balkan endemic nephropathy and urinary tract tumours. It is also thought to be a cause of testicular cancer. A previous study has shown that consumption of foods contaminated with ochratoxin A during pregnancy induces lesions in testicular DNA of male offspring, and this supports a possible role for OTA in testicular cancer. Additionally, prenatal exposure to ochratoxin A in mice significantly depresses expression of the DMRT1 gene in male offspring, and the loss of this gene produces germ cell testicular tumours in mice. This molecular evidence supports the theory that ochratoxin A might be related to germ cell testicular tumours in mice and in humans.
Keywords: ochratoxin A, testicular cancer, mycotoxins

Welding of titanium alloys with steels presents a high risk of cold cracking because of the formation of extremely brittle intermetallic phases associated with residual stress. The use of solid state and diffusion‐based methods as well as a high power beam welding allow so far to achieve good tensile properties through the control of a local phase content. This review summarizes existing approaches for the creation of defect‐free joints between titanium alloys and steels: direct joining without a filler material, the use of insert having full metallurgical compatibility with titanium, the use of insert compatible with stainless steel, and multilayer engineering.

A prospective study was conducted on 73 allergic patients and 14 normal volunteers in order to measure the IgE concentration in both serum and saliva, and analyze salivary IgE according to the characteristics of the allergic disease. IgE was more frequently detected in saliva from allergic patients than from normal subjects, but its concentration was not significantly higher in the allergic group. The IgE concentration in saliva was not related to serum IgE or to the type of syndromes of the allergic disease, but increased with the symptoms during the pollen season in patients suffering from pollen-induced rhinitis and conjunctivitis.

The temperature dependence of the c-axis optical conductivity sigma(omega) of optimally and overdoped YBa2Cu3Ox ( x = 6.93 and 7) is reported in the far- (FIR) and midinfrared (MIR) range. Below T(c) we observe a transfer of spectral weight from the FIR not only to the condensate at omega = 0, but also to a new peak in the MIR. This peak is naturally explained as a transverse out-of-phase bilayer plasmon by a model for sigma(omega) which takes the layered crystal structure into account. With decreasing doping the plasmon shifts to lower frequencies and can be identified with the surprising and so far not understood FIR feature reported in underdoped bilayer cuprates.

ABSTRACT According to popular accounts, China’s international influence is increasing with its growing material capabilities. However, researchers repeatedly demonstrate gaps between China’s power and its influence. Building on earlier research, we propose an inclusive approach to conceptualizing China’s influence abroad. Our approach conditions China’s net influence on three dimensions. First, intentionality distinguishes between intentional influence-seeking and influence that accrues unintentionally via influence externalities. Second, a systematic treatment of Chinese intermediaries–the diverse set of substate actors operating overseas–is needed in order to expand the study of Chinese influence beyond state-level behavior. Finally, domestic institutions in host countries are essential conduits for conditioning how the behavior of Chinese actors, as well as group and individual reactions within host countries, are aggregated up to the policy level.

Modern deep neural networks achieve impressive performance in engineering applications that require extensive linguistic skills, such as machine translation. This success has sparked interest in probing whether these models are inducing human-like grammatical knowledge from the raw data they are exposed to, and, consequently, whether they can shed new light on long-standing debates concerning the innate structure necessary for language acquisition. In this article, we survey representative studies of the syntactic abilities of deep networks, and discuss the broader implications that this work has for theoretical linguistics.

In this study, we measured D-arabinitol, candida antigen and beta-glucan in the rabbit model of systemic candidiasis. It was recently reported that the factor G, one of the coagulation enzymes from the horseshoe crad amebocyte lysate, reacts with beta-glucan or polysaccharide from fungus, and not with endotoxin. The newly developed endotoxin specific chromogenic Limulus assay (endospecy test), which is devoid of factor G, did not react with any rabbit serum. But the beta-glucan measured by the conventional Limulus assay (toxicolor test), which contains the factor G, was elevated (from 10 pg/ml to 100 pg/ml) in all cases of rabbit model of system candidiasis. Serum D-arabinitol, measured by Sone's enzymatic fluorometric method, increased in all cases, but Cand-Tec (candida detection system by latex agglutination) showed only one positive case in five innoculated rabbits.

* Background & Objectives All critical infrastructure can be modeled as networks, or systems of nodes and connections, and many systems such as the electric grid, water supply, or telecommunications exist explicitly as networks. Infrastructures are interdependent, for instance, telecommunications depend on electric power, and control of the electric grid depends increasingly upon telecommunications, creating the possibility for a negative feedback loop following a disturbance. The performance of these systems under disturbance are related to their inherent network characteristics, and network architecture plays a fundamental role in reliability. What characteristics of networks affect their robustness? Could, for instance, the vulnerability of the electric grid to cascading failure be reduced? * Methods We create a failure model of the network where each node and connection is initially in the operative state. At the first discrete time step a network element is changed to the failed state. At subsequent ...

Objective: To assess the value of immunoglobulin heavy/light chain (HLC) immunoassay on therapeutic response in patients with multiple myeloma(MM). Methods: A total of 45 newly diagnosed MM patients were retrospectively enrolled in Peking Union Medical College Hospital from 2013 to 2016, whose 115 serum samples were consecutively collected. HLC was tested to evaluate response and compare with other methods for M protein detection. Results: ①There were 30 males and 15 females in total of whom the monoclonal immunoglobulin was IgG in 27 (IgGκ∶IgGλ 12∶15) and IgA (IgAκ∶IgAλ 9∶9) in 18. The arerage age of the studied population was 59 (range 43-80) . ② In 34 patients with serum sample at diagnosis, 32 (94.1%) had abnormal HLC ratio (rHLC) while 2 patients with IgG had normal rHLC. The percentages of abnormal rHLC was 81.8% (18/22) at partial response、50.0%(9/18) at very good complete response and 16.0%(4/25) at complete response. ③In 25 patients reaching CR, there were 13 with IgG and 12 with IgA. 4 patients equally split of IgG and IgA had abnormal rHLC at complete response. ④By monitoring the rHLC of some patients consecutively, we found that the remission of rHLC was to some extent behind the remission of SPE and IEF, or even rFLC. Conclusion: Immunoglobulin HLC detection is one feasible method for minimal residual disease detection.

In East Texas/North Louisiana Basin, the basinal sediments are often nearly flat-layered in their upper part and overly deep basement rocks. This geological structure creates a favorable subsurface environment for detection of residual gravity anomalies associated with elements of subsurface structure in the middle part of the sedimentary section. Within this depth range, a number of wells penetrated shales and reservoir quality sands and allowed the recognition of two types of stratigraphic plays. These plays are modeled as the “incised valley” and “lateral thinningout” facies.

The attribute set/attitude model relationship recently proposed by Myers and Shocker was examined using correlational and (LISREL) causal analysis. Compared against more traditional single-attitude model approaches (Ahtola, Adequacy-Importance, and Fishbein), Myers and Shocker's mixed model appears promising. It matched the attitude model which best predicted behavioral intentions for two out of three product attribute sets, and along with the Fishbein model, produced a satisfactory fit with the hypothesized causal structure. However, when the alternative attitude models were compared using a multiple indicator approach, results suggest these models do not appear to be directly measuring the same underlying attribute sets.

Background: Few studies have investigated the effect of early childhood caries (ECC) on Peruvian children; there are even fewer studies of how ECC and treatment needs (TNs) affect the quality of life of these children. Objective: To assess the impact of oral health on the quality of life, according to ECC and TNs, of Peruvian preschool children. Materials and methods: A descriptive cross-sectional study was conducted, consisting of a sample of 360 children aged 3 to 5 years from a public educational institution in the district of Independencia, Lima. The children were examined using the decayed, missing, and filled teeth (DMFT) index, the TNs index, and the early childhood oral health impact scale (ECOHIS) questionnaire. The data were analyzed with descriptive statistics using ANOVA and the KruskalWallis test to establish relationships (p<0,05). Results: The prevalence of ECC was 73.6%, and the most required TN was “surface filling.” Statistically significant differences were found for both ECC and TNs in relation to all quality of life domains. Conclusions: ECC and TNs have a negative impact on the quality of life of preschool children

With the development of information systems, data has become one of the most important sources of organizations. Therefore, methods and techniques are needed to efficiently access data, share data, extract data from data, and use this information. By creating and expanding the Web and a significant increase in the volume of information and web development, the need for methods and techniques that can provide data efficiently and extract information from them is felt more than ever. Web mining is one of the areas of research that uses data mining techniques to automatically discover information from web services and documents. In fact, Web mining is a process of discovery of unknown and useful information from web data. Web mining methods are categorized into three types of web content exploration, exploration of Web structures, and exploration of the use of the Web, based on what type of data they are exploring. This research investigates the relationship between the idea of mining and other research fields and examines some of the previous methods used. Finally, a method is proposed based on two decision tree and machine model algorithms that will improve the results of the idea of mining. The results of the simulation of the proposed method were evaluated and compared with the previous methods. The results show that the proposed method has higher accuracy and speed

The purpose of this study was to test the effects of an individually focused, guided decision-making intervention on individuals' perception of self-care ability following a stroke. A convenience sample of 68 individuals participating in four stroke rehabilitation programs in southeast Florida participated in the study. A quasi-experimental design using a pretest and a posttest was implemented. Findings indicated the potential effectiveness of this intervention in significantly increasing individuals' perceptions of their self-care ability after a stroke. Implications for practice and future research are discussed.

This study examines whether rainfall and its effects on food availability control the timing of migratory movements and breeding activity in the Namaqua Sandgrouse, Pterocles namaqua. Namaqua Sandgrouse exhibit a pattern of partial migration between two late-summer-rainfall regions, birds spending the summer months in the Nama Karoo and the winter months in the Kalahari. Across southern Africa, the breeding season for this species is unexpectedly variable, and not consistently correlated with periods of peak food availability. The main egg-laying periods in the late-summer-rainfall regions are: (a) in northwestern Namibia from January–May with a peak in May, (b) in southwestern Namibia in any month with a peak in July, (c) in the Kalahari from June to December, and (d) in the Nama Karoo from September to December. Breeding in the Nama Karoo often starts five months after food becomes abundant, and extends into the start of the rainy season, when food availability can reach the lowest levels in the annual cycle. This suggests that some factor(s) other than proximate food availability is/are involved in determining the timing of movements and breeding in this species, at least in some regions. The possible complicating influences of biannual breeding, moulting, adult nutritional reserves and seasonal variation in nest predation pressure are discussed. We conclude that further long-term monitoring throughout the range of the Namaqua Sandgrouse is required to unravel the potential contribution of three factors (food availability, pottern of migratory movement and risk of nest predation) to the timing of migratory movements and breeding seasons in this species.

Millennial or Generation Y is a group of people born after Generation X, namely people born in the range of 1980-2000. Now, this generation is between the ages of 17-37. There are some millennial students who have dropped out of school or graduated from universities and entered to work, but most of them are still in the school system. The image and concept of the teacher in contemporary society is very much different from the concept of the past. The past teacher means knowledgeable, wise, and prudent. Nowadays, teachers are seen as educational functionaries who are tasked with teaching on the basis of certain scientific and academic qualifications. With this task, the teacher receives material rewards from the state or the education manager. Thus, the most important factor in the teaching profession is scientific and academic qualifications. Meanwhile, wisdom and prudence which are moral attitudes and behaviors are no longer significant. In the classical concept, moral factors are above teacher qualifications. In general, teachers should understand the social changes that exist in the present. Teachers must not stop learning about new things. Global challenges in the current era are also different from the global challenges from the past. Whatever steps and methods carried out at school are certainly aimed at forming character and preparing quality human resources in Indonesia. In this paper, the author will outline the challenges for teachers in the millennial era and the efforts made in dealing with these challenges. Previously the author also explained about the millennial generation, and the professionalism of teachers.
