The Great Financial Crisis shows that bank failure in the United States, while rare, is a concern during uncertain times. Interest here is in the ability to predict future failures at the start of a crisis, when the recent past has few events on which to base inferences. I show that policy makers using estimates based on the Savings and Loans crisis would identify in early 2009 that 2.0% of banks were in critical condition and 7.0% were unhealthy. This is comparable to the 1.7% of banks that failed within a year and the 3.9% of banks that would fail during the crisis.

The Randeck Maar lake sediments from southwestern Germany were deposited during the late Early to early Middle Miocene (mammal zone MN 5). Although historically well known as an important fossil Lagerstätte, there are few works that have dealt specifically with the fossil gastropods (no bivalves have ever been found). A revision is presented herein of all the material available from the site, both from historical museum collections and from new excavations, figuring much of these gastropods for the first time. The snail fauna of the Randeck Maar now comprises a total 32 continental gastropod species, among which only four are freshwater: Lymnaea cf. dilatata, Ferrissia deperdita, Gyraulus kleini and Planorbarius cornu. The terrestrial snail fauna consist mostly of land-dwelling pulmonates, being dominated by the following species: Pomatias conicus (the only operculate snail in the fauna), Cochlicopa loxostoma, Granaria sp. and Praeoestophorella phacodes. Finally, the following species are reported for the first time from Randeck Maar: Clausiliinae indet., Triptychia kleini, Palaeotachea renevieri, Deroceras sp., Milax sp., Gastrocopta sandbergeri, Testacella zellii. Such a diverse snail fauna might help elucidate paleoecological questions regarding the Randek Maar lake and its hinterland.

The present study was conducted in order to evaluate the use of slaughter offal preserved by lactic acid fermentation in pig diets. Offal was first ground, autoclaved, and mixed with 70 kg sugar beet molasses per 1000 kg. After that it was inoculated with 2x105 lactic acidbacteria/g and incubated at 35°C for three days. The final pH of the fermented product was 3.80. The ensiled slaughter offal (ESO) contained 239 g dry matter (DM)/kg. and 319 g crude protein (CP) and 403 g crude fat (CF)/kg DM. CP contained 47 g lysine, 33 g threonine, 16 g methionine, and 8 g cystine/kg. A digestibility and nitrogen (N) balance assay was conducted with eight barrows using a 2x4 factorial arrangement in a Bx 4 cyclic change-over design. The factors were protein source and protein level. Barley-based diets were supplemented with increasing levels (0, 20,40, and 60 g CP/kg) of ESO or soyabean meal (SBM). Increasing the protein supply led to a linear increase in the digestibility of CP (pcO.OOl) and a quadratic increase in the digestibility of CF (p<0.001). The apparent digestibility of organic matter, CP, and CF calculated by the regression method was 0.811, 0.898, and 0.789 for ESO and 0.849,0.867, and 0.731 for SBM, respectively. N retention increased linearly with increasing protein supply (p<0.001), but no significant differences were observed between protein sources. Although the amount of N excreted in urine was higher (p<0.05) for ESOthan SBMsupplemented diets, there were no significant differences in urea-N excretion between protein sources. The daily weight gain increased linearly with increasing protein supplementation (pcO.OOl) and was higher for SBMthan for ESO-supplemented diets (p<0,05). A growth trial was conducted with 216 pigs using a randomized complete block design. No significant differences were observed in growth performance, feed consumption, or feed conversion rate between the control diet and the test diet. ESO provided 0.20 of DM and 0.22 of feed units of the test diet. Carcass weight and thickness of both back and side fat were similar on both treatments (p>0.05), whereas dressing percentage was higher in pigs fed the test diet (p<0.01). No significant differences were found in the chemical composition or organoleptic scores of the longissimus dorsi muscle between the treatments.

Mutations detected in cancers are often divided into “drivers” and “passengers.” We suggest that this classification is potentially misleading for purposes of early detection and prevention. Specifically, some mutations are frequent in tumors and thus appear to be drivers, but are poor predictors of cancer; other mutations are individually rare and thus appear to be passengers, but may collectively explain a large proportion of risk. The assumptions bundled into the terms “driver” and “passenger” can lead to misunderstandings of neoplastic progression, with unintended consequences including overdiagnosis, overtreatment, and failure to identify the true sources of risk. We argue that samples from healthy, benign, or neoplastic tissues are critical for evaluating the risk of future cancer posed by mutations in a given gene. Cancer Prev Res; 9(5); 335–8. ©2016 AACR.

Chronic hepatitis B (CHB) is a major cause of morbidity and mortality worldwide; and as a result imposes a considerable burden on the patient, their family, and society. The disease is a global healthcare problem and has huge implications on economic healthcare expenditure. Approximately 350 million people are chronic carriers of hepatitis B and, of these, one-third is expected to develop complications arising from hepatitis B infection, resulting in cirrhosis, hepatocellular carcinoma (HCC), liver failure, or death.

A novel CO2 capture phenomenon is observed by modifying as‐prepared mesoporous silica SBA‐15 (SBA(P)) with tetraethylenepentamine (TEPA), not only conserving the energy and time required for removing the template, but also opening the way to utilizing the micelle for dispersing guest species. The TEPA species dispersed within the channels of SBA(P) are highly accessible to CO2 molecules; moreover, the hydroxyl group of the poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) (Pluronic P123) template is able to modify the interactions between CO2 and the amine to enhance the adsorptive capacity of this system. The remarkably high adsorption capacity (173 mg g–1) of this mesoporous silica–amine composite suggests potential CO2 trapping applications, especially at low CO2 concentrations during prolonged cyclic operations.

L’articolo affronta il tema delle politiche abitative a partire dal Sistema Integrato di Fondi immobiliari, una linea di intervento del Piano Casa 2008 che, per incidere positivamente sul bisogno abitativo delle fasce sociali definite ‘a rischio’, individua il fondo immobiliare come strumento per raccogliere risorse sia pubbliche sia private. Discostandosi dalla retorica dell’innovazione, l’articolo mette in luce effetti e implicazioni dell’utilizzo di uno strumento di natura privatistica e finanziaria in termini di orientamento delle politiche abitative e di perseguimento di interessi collettivi diffusi. Ne indaga i meccanismi di funzionamento, la rilevanza all’interno del contesto politico e definitorio dell’alloggio sociale e, attraverso una lettura dei progetti in corso d’opera in Lombardia, individua elementi utili ad una prima valutazione degli esiti materiali della politica

and space, an all-encompassing medium of exchange, a durable system of payment, but also a protean, virtualized, and volatile means for the enrichment of the few and the enslavement of the many. This fundamentally problematic and ambiguous aspect of money lies at the heart both of Pete North’s account of Money and Liberation and of the numerous experiments in “alternative” currencies that he explores in the course of it. The basic idea is that under the right conditions, money can be a tremendously positive and liberating element in the lives of the poor and the marginal. Specifically, North explores the long history of people and communities that have used the uniquely transformative power of money to resist both the idea and the practice of a hegemonic capitalism. In all cases, these experiments are founded on the realization that money can be produced by anyone, anywhere—all one needs are an agreed system of exchange value (time, labor, paper, or shells) and the collective will to do it. That collective will emanates from many different sources, and North carefully charts the efforts of utopian socialists, anarchists, environmentalists, communitarians, and, more practically, people who face severe economic hardship to harness it in the pursuit of alternative money. As this account implies, for all their common goals, the nature and outcomes of the experiments examined in the book vary enormously. The alternative schemes range from largely theoretical attempts to steer modern capitalism away from the hegemony of the bankers and the industrialists (like the social credit movement) to the more concrete manifestations of local and “barter” currencies (such as local exchange trading systems, “green” dollars, and antipoverty programs in Hungary and Argentina). North combines a series of case studies of these various experiments, based on his own extensive empirical research, with an overview of some of the main theoretical issues surrounding the development of modern money. One of the great strengths of the book is that it does not succumb to the temptation to “overtheorize” the problem of money—which much of the more recent literature on money has done all too often. Rather than get bogged down in the interesting but often fruitless arguments about whether money is “real,” North’s empirical focus demonstrates both the ways in which ordinary people can and do use money’s potential for freedom and the difficulties of sustaining the good it can do. As this focus implies, there is no way around the fact that, at one level, this is a book about the ultimate failure of any of the currency experiments to deliver any lasting or widespread change. Some are defeated by the power of the mainstream economy, some by direct repression, some by differences and squabbles that emerge within the movements that have created the alternatives. Although it would be easy to conclude that alternative currencies are therefore pointless, North’s optimism is such that he refuses to do so. The fact that such experiments did not survive in the past neither denies the short-term gains that many were able to deliver—particularly as coping strategies for the very poor—nor prevents them, in North’s view, from succeeding in the future. Specifically, North sees, in the socioeconomic spaces being opened up by the Internet, the possibility of new modes of interaction, value construction, and (nonor anticapitalist) exchange that could overcome some of the inherent limitations of local and/or small-scale alternative currencies. Whether this is likely, given that mainstream capital seems to have managed to both engender and occupy many of the available “spaces” of the Internet, is debatable.

A 26-year-old man with a one-year history of asthma and sinusitis presented with bilateral pleural effusions, patch basilar infiltrates on a chest x-ray and a pericardial effusion on an echocardiogram. The peripheral blood showed marked eosinophilia. An obstructive pattern was also observed during the pulmonary fuction test, which was responsive to bronchodilator inhalation. Nerve conduction studies showed right sural neuropathy. Thoracentesis yielded an acidotic exudative effusion with low glucose, low and eosinophilia. An open lung biopsy revealed an eosinophilic interstitial pneumonitis associated with a necrotizing eosinophilic vasculitis, and granulomatous inflammation foci. In the literature, pleural effusions were reported in 29 percent of Churg-Strauss patients, but the number of effusions was low and their characteristics have not been well described. This report describes the characteristic findings of pleural fluid and its histologic features in a case of classical Churg-Strauss syndrome.

An image deblurring algorithm based on non-local means denoising and Bregman iteration algorithm is proposed. Non-local total variation (NLTV) regularization term in Bregmanrized operator splitting (BOS) algorithm was replaced with l2 non-local norms, and a iterative three step deblurring scheme with fast non-local denoising algorithm was given. Based on the symmetry of weighted Euclidean distance, the most complex distance computation in non-local means was halved for every pair of pixels. Experimental results show that proposed algorithm obtained better results on ten common test images than NLTV regularization, both in deblurring performance (PSNR and MSSIM) and processing speed.

Popliteal artery entrapment syndrome is the compression of the popliteal artery and is the main cause of intermittent claudication in young patients. An 18-year-old man was admitted at our service complaining of right foot paresthesia, coldness, and pallor that appeared 24 hours after physical activity. Posterior tibial and dorsal artery of foot pulses were not present in right lower limb. Diminished posterior tibial and dorsal artery of the foot pulses were found in left lower limb at dorsal flexion and forced plantar flexion. After surgery, both pulses were present. This syndrome is more frequent in men and its prevalence varies between 0.16 and 3.5%. Popliteal artery entrapment type III is most common. Non-treated entrapment can lead to embolism, thrombosis and post-stenotic aneurysms. The syndrome must be considered as a cause of lower limb pain specially in young men with intense sport practice history.

While recent changes in subarctic North Pacific climate had dramatic effects on ecosystems and fishery yields, past climate dynamics and teleconnection patterns are poorly understood due to the absence of century‐long high‐resolution marine records. We present the first 117‐year long annually resolved marine climate history from the western Bering Sea/Aleutian Island region using information contained in the calcitic skeleton of the long‐lived crustose coralline red alga Clathromorphum nereostratum, a previously unused climate archive. The skeletal δ18O‐time series indicates significant warming and/or freshening of surface waters after the middle of the 20th century. Furthermore, the time series is spatiotemporally correlated with Pacific Decadal Oscillation (PDO) and tropical El Niño‐Southern Oscillation (ENSO) indices. Even though the western Bering Sea/Aleutian Island region is believed to be outside the area of significant marine response to ENSO, we propose that an ENSO signal is transmitted via the Alaskan Stream from the Eastern North Pacific, a region of known ENSO teleconnections.

In recent years, Russia has been working on an option of creating a super-heavy-class Yenisei space rocket designed to implement long-range programs for exploring the Moon and deep space. At the moment, the project has been suspended, but the task is still relevant. The paper comparatively analyses the dynamic processes occurring at certain operational stages of the installation unit during the verticalization of the super-heavy-class Yenisei space rocket. In order to select their optimal design, we examined several designs of certain units and elements of the rocket verticalization system. The rocket configuration introduced in this paper was used to evaluate the functioning of the installation unit, whose design can be further modified for a new product. The relevance of the study lies in the analysis of specific operating modes of a fundamentally new type of installation units, which has not previously been used in Russia and the USSR. Relying on the calculations, we found the most suitable configuration of the nodes and elements of the verticalization system. Design solutions were proposed to reduce the dynamic loads on the rocket in the process of lifting and installation on the launch pad.

Computer aided diagnosis of dermoscopy images has shown great promise in developing a quantitative, objective way of classifying skin lesions. An important step in the classification process is the lesion segmentation. Many papers have been successful at segmenting melanocytic skin lesions (MSLs) but few have focused on non-melanocytic skin lesions (NoMSLs), since the wide variety of lesions makes accurate segmentation difficult. We developed an automatic segmentation program for the border detection of skin lesions. We tested our method on a set of 107 non-melanocytic lesions and on a set of 319 melanocytic lesions. Our method achieved precision/recall scores of 84.5% and 88.5% for NoMSLs, achieving higher scores than two previously published methods. Our method also achieved precision/recall scores of 93.9% and 93.8% for MSLs which was competitive or better than the two other methods. Therefore, we conclude that our approach is an accurate segmentation method for both melanocytic and non-melanocytic lesions.

Objectives
Vitamin K is an essential nutrient that has been implicated in cardiovascular disease and other chronic diseases. There are two forms of vitamin K in nature. Phylloquinone (PK) is plant-based and has been well-quantified in the U.S. diet. Menaquinones (MK) are found in animal products and fermented food. However, the MK contents of food have not been well characterized. The objectives of this study were to: 1) quantify the different forms of MK (MK4 through MK13) in the beef variety meat items; and 2) determine if cooking has an effect on vitamin K content of beef variety meat items.
Methods
Raw beef heart, liver, kidney, tongue, honeycomb tripe, oxtail, bone marrow, beef rocky mountain oysters (RMO), fat composite samples and blood (total samples n = 31) were obtained from processing facilities in the U.S., to provide national representation of retail-ready beef variety meat items. All raw beef samples were cooked, and final internal temperature was 80 °C. PK and the MKs in raw and cooked beef variety meat items were quantified using mass spectrometry technology. Wilcoxon Rank Signed test was used to compare PK and MK contents of raw and cooked samples. Differences were considered statistically significant at P < 0.05.
Results
The highest concentration of any form was PK in bone marrow at 152 ± 11.9 ng/g. The fat composite samples contained between 20.9 ng/g to 63.0 ng/g of PK. Modest amounts of PK were found in liver, RMO and tripe. MKs were present in all samples analyzed with MK4, MK10, MK12 and MK13 present in the largest amount in the analyzed samples. MK4 concentrations in bone marrow and fat composite samples were 341 ± 116 and 374 ± 101 ng/g, respectively. Liver contained appreciable amounts of longer-chain MKs, primarily in the forms of MK11, MK12 and MK13, which together accounted for 95% of total vitamin K in liver. There were no significant differences in total vitamin K content between cooked and uncooked beef variety.
Conclusions
To the best of our knowledge, this is the first report of MK contents of U.S. beef variety meat items. The vitamin K content of beef items were not influenced by cooking (heating).

Abstract Objective: There are contrasting positions concerning the benefit–risk ratio of acetaminophen use for osteoarthritis (OA)-related pain. To clarify the effectiveness of acetaminophen or acetaminophen–codeine combinations according to their regimen of use, we evaluated whether being a regular user (adherent) of these medications decreased the occurrence of rescue therapy with non-steroidal anti-inflammatory drugs (NSAIDs). Methods: Using the Health Search IMS Health Longitudinal Patient Database, we formed a cohort of patients aged ≥18 years and newly treated with acetaminophen or acetaminophen–codeine combinations for OA between 1 January 2001 and 31 December 2013. These patients were followed up for one year in which they were categorized as regular or irregular users of these medications according to a variable medication possession ratio (VMPR) ≥ 50% or lower. We operationally defined the rescue therapy as the use of any NSAIDs prescribed for OA-related pain. Results: Overall, 40,029 patients (69.5% females; mean age: 68 ± 13.57) treated with acetaminophen or acetaminophen–codeine combinations formed the cohort. After the first year of treatment, regular users showed a statistically significantly lower risk of being prescribed with rescue therapy with NSAIDs (OR = 0.89; 95% CI 0.84–0.96). Conclusion: These findings show that regular use of acetaminophen or acetaminophen–codeine combinations may reduce the need for NSAIDs to treat OA-related pain.

骨関節，脳血管，循環器などの各疾患で理学療法依頼のあった47人を対象に，血圧脈波検査装置を用い，Cardio Ankle Vascular Index（CAVI）を測定し検討した。CAVIは，四肢の動脈硬化傾向を示すものであり，高血圧，狭心症，糖尿病の3疾患のうち，2つ以上の疾患に罹患している群とそれ以外の群で有意差を認め，狭心症既往の有無でも有意差を認めた。このことは，重篤な末梢循環障害や冠動脈疾患へ発展する可能性を示しており，運動療法を実施する上で注意が必要なことを意味している。運動療法前に血圧脈波検査を施行することは，運動負荷における有益な一情報と考えられた。

During a 24-month survey, 539 samples each of the Eastern oyster, Crassostrea virginica, and the overlying water were collected to determine the relation of most probable number (MPN) of the total and fecal coliform groups in shellfish and water to the presence of Salmonella in the shellfish themselves. Occurrence of Salmonella in the shellfish more closely paralleled a progressive increase in the fecal coliform MPN as compared to the total coliform MPN in the water and shellfish meat. The percentage of Salmonella-positive shellfish samples was somewhat higher in oysters harvested from waters conforming to the present bacteriological approved growing area standard of ≤70 total coliforms per 100 ml water as compared to these same waters meeting a recently proposed fecal coliform standard of ≤14 organisms per 100 ml. In no instance was Salmonella detected in oysters from growing areas officially approved for harvesting on the basis of both a bacteriological and sanitary survey. Of a variety of enrichment br...

Malnutrition is a common and costly problem in the UK. Prevalence varies according to setting, from 5% in GP surgeries to 42% in care homes; however, malnutrition is frequently undetected. A variety of nutrition screening tools have been produced, measuring a range of nutritional parameters. Guidance from the National Institute for Health and Clinical Excellence (NICE) recommends the use of a tool such as the Malnutrition Universal Screening Tool (MUST) to screen for malnutrition risk in both hospitals and the community. This article discusses the prevalence of malnutrition according to MUST both in hospitals and the community. It also considers the association between malnutrition and deprivation, healthcare outcomes and cost, and the role of training in increasing nutritional screening use and appropriate care plans. There is a need to ensure that all people accessing healthcare services are screened for malnutrition, and that nutritional care plans and interventions are initiated, monitored and reviewe...

Background and objectives: The aim of the study was to evaluate the shear bond strength of brackets bonded with three bonding systems under laboratory conditions and to compare resin tag penetration after debonding. Materials and methods: The study was done on 60 extracted human premolar teeth, divided into three groups of 20 teeth each. Each group was bonded with three different types of bonding systems namely, the single component bonding system—Biofix, conventional light cured bonding system—Transbond XT and conventional chemical cured bonding system—Unite. The shear bond strength of the bonding system in each group was tested using Instron testing machine. After debonding, the samples were sectioned and viewed under scanning electron microscope to evaluate the resin tag penetration. The depth of penetration was measured with the measuring tool in the scanning electron microscope and marked. Results: The study revealed that the group bonded with Biofix has got the enough bond strength as the conventional chemical cured bonding system, Unite. The resin tag penetration into enamel was seen to be highest for Transbond XT, and for Biofix and Unite it was comparable and less. Conclusion: The shear bond strength values for Biofix is above the needed value to sustain normal oral and orthodontic forces and the residual resin tag remained after debonding are also less. Hence, the single component bonding system Biofix can be considered as a good material of choice for normal clinical bonding procedures.

Alleles with differing epigenetic marks in the same nucleus, such as when divergent epigenomes come together in a hybrid, can interact in trans to modify the epi-genetic state of each other. In this issue of Epigenetics, Greaves et al. describe the mechanisms involved in trans-chromo-somal methylation (TCM) and trans-chromosomal demethylation (TCdM), and the effect they can have on genome activity. Trans-allelic epigenetic interactions may be a common occurrence in many biological systems. A subset of HDACs regulate the integrity of the genome by stabilizing enzymes important for DNA mutagenesis and repair, or by modifying histones at sites of DNA damage. Certain HDACs in budding yeast and human cells even accelerate the pace of genetic expansions in trinucle-otide repeats, the type of mutation that causes Huntington disease. Interestingly, the same HDACs in budding yeast help stabilize the genome by facilitating homol-ogy-dependent and homology-independent repair. Lahue and Frizzell now review the role of these HDACs in genome stability , underscoring the potential therapeutic use of HDAC inhibitors in the treatment of disease. The nucleolus, the most active site of transcription , is also an attractive compartment for nuclear heterochromatic regions, such as pericentric repeats, inactive X chromosome and regions with low gene density significantly enriched in repressed genes. The coexistence of euchromatic and heterochromatic rRNA genes in each cell reflects these two opposite functions of the nucleolus. An epigenetic network that is controlled by the NoRC complex establishes and maintains rDNA heterochro-matin. Guetg and Santoro now discuss how heterochromatic rRNA genes and the associated epigenetic regulatory activities might mediate formation and inheritance of nuclear heterochromatic regions. Migliori et al. review the function of WD40 proteins as a new class of histone readers, with particular emphasis on the ones able to recognize methylated arginine and lysine residues. The authors focus on WDR5, a classical seven-bladed WD40 propeller, that is able to bind with similar affinities both the catalytic subunit of Trithorax-like complexes and histone H3 tails, either unmodified or symmetrically dimethylated on arginine 2 (H3R2me2). These mutually exclusive interactions of WDR5 may play a role in mediating different degrees of H3K4 methylation at both promoters and distal regulatory sites. A large and complex network of epigen-etic modifications play important roles in human stem cells and govern the fine-tuning of gene expression programs that define the molecular basis of stem cell pluripotency, differentiation and reprogramming. Tollervey and Lunyak review the processes that govern the …

We have investigated Scoparia dulcis, an indigenous plant used in Ayurvedic medicine in India, for its possible antihyperlipidemic effect in rats with streptozotocin-induced experimental diabetes. Oral administration of an aqueous extract of S. dulcis plant (200 mg/kg of body weight) to streptozotocin diabetic rats for 6 weeks resulted in a significant reduction in blood glucose, serum and tissue cholesterol, triglycerides, free fatty acids, phospholipids, 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase activity, and very low-density lipoprotein and low-density lipoprotein cholesterol levels. The decreased serum high-density lipoprotein cholesterol, anti-atherogenic index, and HMG-CoA reductase activity in diabetic rats were also reversed towards normalization after the treatment. Similarly, the administration of S. dulcis plant extract (SPEt) to normal animals resulted in a hypolipidemic effect. The effect was compared with glibenclamide (600 microg/kg of body weight). The results showed that SPEt had antihyperlipidemic action in normal and experimental diabetic rats in addition to its antidiabetic effect.

In this study, the ability of bacterial strains isolated from the textile mill site was analyzed for de-colorization of dye effluent. The isolated strains were finally identified by 16S rDNA sequence analysis as Bacillus species and were used for the process of bioremediation. The physicochemical characterization of the effluent generated was also carried out. The effluent was analyzed for its physicochemical properties before and after treatment. Samples were analyzed in UV spectrophotometer and showed the absorption maxima at wavelength of 668 nm. The bacterial strain was found to have sorptive capacity, immobilized on nutrient agar medium. The effluent was treated in a flask containing minimum salt medium, 20% dye effluent and 5% (w/v) of bacterial pellet. The flask was placed in an incubator shaker at 37°C and 200 rpm. After inoculation the sample was analyzed in visible spectrophotometer after every six hours and it was found that 90% de-colorization and 70% reduction in COD was achieved after 24 hours. Heavy metals were also biosorptioned. It was concluded that the isolated bacteria represented a promising application in bioremediation process of textile industrial effluent and possible reusability of the cells for its commercial application can be achieved.

Iis often difficult to establish whether certain patients should he given the diagnosis of bipolar disorder, borderline personality disorder, or both. This case high- lights how knowledgeable psychi- atnists can have contrasting diag- nostic views about patients with volatile moods and impulsivity and how such disagreement can create problems in providing effective treatment. The patient described in this case report conceptualized her psychiatric problem as due to hipo- lan disorder, which she was told meant a biochemical illness charac- tenized by mood swings not under her control. She was told that this genetically determined disease could he stabilized by using the proper combination of medica- tions. This conceptualization of her illness sharply contrasted with the diagnosis developed during consul- tation-horderline personality dis- order. At that point the patient was told that she suffered from a psy- chiatnic disorder caused by devel- opmental difficulties that are best treated by psychosocial treatments, with psychopharmacology as an adjunctive treatment. With this di- agnosis she was expected to in- creasingly take responsibility for managing her mood swings and im-

Abstract The new generation of clinical chemistry and coagulation analyzers is equipped with technical features allowing a systematic check of sample quality, including an assessment of the so-called HIL (“hemolysis”, “icterus”, “lipemia”) indices. These measures enable an accurate and reproducible assessment of sample hemolysis in serum or plasma, hence the hemolysis index (H-index) is now also increasingly used for monitoring and benchmarking phlebotomy performance. Reliable evidence attests that intravascular hemolysis is not such a rare phenomenon, and its prevalence may be especially higher in geographical areas where congenital hemolytic diseases are endemic, as well as in healthcare settings where patients with acquired hemolytic disorders are more frequently visited or hospitalized. It is hence conceivable that monitoring phlebotomy performance based on the rate of hemolyzed specimens received by the laboratory may not be so straightforward, provided that specimens drawn from patients with intravascular hemolysis can be identified and excluded from the analysis. The aim of this article is to provide an overview of potential drawbacks in using the H-index alone for monitoring phlebotomy performance, and to offer potential solutions to improve its efficiency for this scope. We therefore suggest that the H-index may only be used for purposes of benchmarking phlebotomy performance when the overall number of diagnoses of hemolytic diseases or the haptoglobin values measured by the laboratories are comparable across different healthcare settings or geographic areas.

Objective: To determine diagnostic accuracy of quadruple phase helical computed tomography scan in detection
of hepatocellular carcinoma in individuals with hepatitis B and C, keeping histopathology as the gold standard.
Methods: A cross-sectional study was performed in the Radiology and Imaging department of a tertiary care
university hospital during 2014 to 2016. All serologically positive patients were included. Quadruple phase
computed tomography scan was done and results were interrelated with histological diagnosis.
Results: Hepatocellular carcinoma was accurately diagnosed in 76 out of 80 patients using Quadruple phase
computed tomography scan (sensitivity, 95%). It was correctly excluded in 70 of 72 patients (specificity, 97.2%).
The overall diagnostic accuracy of Quadruple phase computed tomography scan for diagnosing hepatocellular
carcinoma was 96.05%. The positive and negative predictive values were 97.4% and 94.59% respectively.
Conclusion: Quadruple phase computed tomography is more effective in evaluating hepatocellular carcinoma
than conventional biphasic and triphasic computed tomography scans. We propose it as the technique of first
preference for imaging workup in patients with Hepatitis B and C.

The Lattice Boltzmann Method (LBM) is an alternative numerical method based on the kinetic theory that has gained its popularity due to its simplicity, easy implementation, and capability to solve problems with simple and complex geometry. Although LBM has been successfully applied to various hydrodynamical problems, there is little literature on applying the LBM to free surface problems. In this paper, the free surface lattice Boltzmann method is used to solve two-dimensional dam-break problems. A typical volume-of-fluid method is incorporated into the LBM to track the movement of the free surface. The fluxes between cells are calculated by their mass exchange, i.e., by considering their distribution functions. To take into account the turbulence of the flow and to ensure the stability of the model, the Smagorinsky sub-grid model is incorporated into the LBM. Three cases of dam-break flows are studied, namely, dam breaks over a dry bed, a wet bed, and a solid obstacle. Our numerical simulations are very much in line with the existing experimental measurements.The Lattice Boltzmann Method (LBM) is an alternative numerical method based on the kinetic theory that has gained its popularity due to its simplicity, easy implementation, and capability to solve problems with simple and complex geometry.

Understanding the mechanisms of the mechanical deformation of lamellar crystals at the molecular level is of prime importance to rational design of advanced crystalline polymer materials. Single-molecule force spectroscopy (SMFS) can directly characterize molecular behavior and kinetic parameters that are masked in ensemble measurements. However, current SMFS approach cannot sufficiently manipulate a single molecule in air, which is the real working condition for most crystalline polymer materials. Here, we establish an air-phase atomic force microscopy (AFM)-based SMFS method that allows the unfolding of a single helical poly(ethylene oxide) (PEO) chain from the single crystal in air. Our results show that the mechanostability of PEO stem and unfolding potential are significantly enhanced in air compared with the case in liquid. The air-phase SMFS method can achieve a much better force precision of 4 pN even at rapid stretching velocity of ∼100 μm/s. Moreover, some intermediate states (e.g., the movement...

Although the cardiac homeobox geneCsx/Nkx-2.5 is essential for normal heart development, little is known about its regulatory mechanisms. In a search for the downstream target genes of Csx/Nkx-2.5, we found that the atrial natriuretic peptide (ANP) gene promoter was strongly transactivated by Csx/Nkx-2.5. Deletion and mutational analyses of the ANP promoter revealed that the Csx/Nkx-2.5-binding element (NKE2) located at −240 was required for high level transactivation by Csx/Nkx-2.5. We also found that Csx/Nkx-2.5 and GATA-4 displayed synergistic transcriptional activation of the ANP promoter, and in contrast to previous reports (Durocher, D., Charron, F., Warren, R., Schwartz, R. J., and Nemer, M. (1997) EMBO J. 16, 5687–5696; Lee, Y., Shioi, T., Kasahara, H., Jobe, S. M., Wiese, R. J., Markham, B., and Izumo, S (1998) Mol. Cell. Biol. 18, 3120–3129), this synergism was dependent on binding of Csx/Nkx-2.5 to NKE2, but not on GATA-4-DNA interactions. Although GATA-4 also potentiated the Csx/Nkx-2.5-induced transactivation of the artificial promoter that contains multimerized Csx/Nkx-2.5-binding sites, Csx/Nkx-2.5 reduced the GATA-4-induced transactivation of the GATA-4-dependent promoters. These findings indicate that the cooperative transcriptional regulation mediated by Csx/Nkx-2.5 and GATA-4 is promoter context-dependent and suggest that the complexcis-trans interactions may fine-tune gene expression in cardiac myocytes.

The aim of the present study was to know the normal haemato- biochemical profiles of black Bengal goats in Bangladesh. Blood samples were collected from Jugular vein of 20 Black Bengal goats which were divided into 5 groups (4 goats in each group) on the basis of age, sex, nutritional and feeding status. The whole blood was analyzed for hematology, plasma and serum samples for biochemical analysis. The results of the present study demonstrate the normal haemato-biochemical values of the Black Bengal goat breeds with their age specificity. Total RBC (15.15 ± 1.29 million/cumm), haemoglobin (7.04 ± 1.02 g/dl), total WBC (11.64 ± 1.12), differential leukocyte counts of neutrophils (70.89 ± 2.06%), lymphocyte (23.79 ± 1.69%), eosinophil 2.1%), basophil (2.3%), MCV (35.04 ± 0.47) and PCV (26.98 ± 1.49%). This study also reveals the normal bio-logical profile counts as total protein (69.47±2.31 g/L), Albumin (42.47 ± 2.31g/L), Globulin (27.32g/L), Phosphorus (3.46 ± 1.19), blood Urea (22.97 ± 0.58), Creatinine (0.645mg/dl), ALT (20.32U/L), ALP (91.59 U/L), GGT (37.46 U/L), IgG (18.91 ± 1.14 g/L), IgM ( 2.87 ± 0.18g/L), gA (.031 ± 0.12g/L) and IL-6 (1.69±0.15g/ml). The study found higher number of RBC (million/cumm), WBC (Thousands/cumm), and PCV% in the goats of age 3 years and above (18.02 ± 1.27, 14.72 ± 1.19, and 28 ± 3.2), respectively. Besides, Neutrophils% and total protein was found higher (76.289 ± 14.5%, 77.52 ± 8.43 g/L), respectively in the Black Bengal goats of 6 months to 1 year age. Present results stated some significant variation of parameters between goats of various ages; on the other hand, some shows no significant variation at all.

For proper function of the negative electrode of dye-sensitized and perovskite solar cells, the deposition of a nonporous blocking film is required on the surface of F-doped SnO2 (FTO) glass substrates. Such a blocking film can minimise undesirable parasitic processes, for example, the back reaction of photoinjected electrons with the oxidized form of the redox mediator or with the hole-transporting medium can be avoided. In the present work, thin, transparent, blocking TiO2 films are prepared by semi-automatic spray pyrolysis of precursors consisting of titanium diisopropoxide bis(acetylacetonate) as the main component. The variation in the layer thickness of the sprayed films is achieved by varying the number of spray cycles. The parameters investigated in this work were deposition temperature (150, 300 and 450 °C), number of spray cycles (20–200), precursor composition (with/without deliberately added acetylacetone), concentration (0.05 and 0.2 M) and subsequent post-calcination at 500 °C. The photo-electrochemical properties were evaluated in aqueous electrolyte solution under UV irradiation. The blocking properties were tested by cyclic voltammetry with a model redox probe with a simple one-electron-transfer reaction. Semi-automatic spraying resulted in the formation of transparent, homogeneous, TiO2 films, and the technique allows for easy upscaling to large electrode areas. The deposition temperature of 450 °C was necessary for the fabrication of highly photoactive TiO2 films. The blocking properties of the as-deposited TiO2 films (at 450 °C) were impaired by post-calcination at 500 °C, but this problem could be addressed by increasing the number of spray cycles. The modification of the precursor by adding acetylacetone resulted in the fabrication of TiO2 films exhibiting perfect blocking properties that were not influenced by post-calcination. These results will surely find use in the fabrication of large-scale dye-sensitized and perovskite solar cells.

We show that one can reconstruct the shape of a room with planar walls from the first-order echoes received by four non-planar microphones placed on a drone with generic position and orientation. Both the cases where the source is located in the room and on the drone are considered. If the microphone positions are picked at random, then with probability one, the location of any wall is correctly reconstructed as long as it is heard by four microphones. Our algorithm uses a simple echo sorting criterion to recover the wall assignments for the echoes. We prove that, if the position and orientation of the drone on which the microphones are mounted do not lie on a certain set of dimension at most 5 in the 6-dimensional space of all drone positions and orientations, then the wall assignment obtained through our echo sorting criterion must be the right one and thus the reconstruction obtained through our algorithm is correct. Our proof uses methods from computational commutative algebra.

In the paradigm of Internet of Things new applications that leverage ubiquitous connectivity enable together with Big Data Analytics the emergence of Smart City initiatives. This paper proposes to build a closed loop data modeling methodology in order to optimize energy consumption in a fundamental smart city scenario: smart buildings. This methodology is based on the fusion of information about relevant parameters affecting energy consumption in buildings, and the application of recommended big data techniques in order to improve knowledge acquisition for better decision making and ensure energy efficiency. Experiments carried out in different buildings demonstrate the suitability of the proposed methodology.

It has been shown that the Internet environment has rapidly changed from fixed to mobile one with the wide popularity of smart phones and the emergence of various wireless/mobile networks. Thus, in research community there has been a consensus that separating Identity (ID) from Locator (LOC) is a one promising concept to address intrinsically such a change. In this paper, we propose a mathematical model to analyze the average total cost for ID/LOC separation schemes and analyze the packet delivery cost using the proposed model for cost-effectiveness of ID/LOC separation schemes in supporting mobility, where reliable packet delivery and local caching mechanism are assumed. We provide a factor of packet delivery cost for cost-effectiveness of ID/LOC separation schemes comparing to mobile IP.

This report investigates the role of compressive stress on ovarian cancer in a 3D custom built bioreactor. Cells within the ovarian tumor microenvironment experience a range of compressive stimuli that contribute to mechanotransduction. As the ovarian tumor expands, cells are exposed to chronic load from hydrostatic pressure, displacement of surrounding cells, and growth induced stress. External dynamic stimuli have been correlated with an increase in metastasis, cancer stem cell marker expression, chemoresistance, and proliferation in a variety of cancers. However, how these compressive stimuli contribute to ovarian cancer progression is not fully understood. In this report, high grade serous ovarian cancer cell lines were encapsulated within an ECM mimicking hydrogel comprising of agarose and collagen type I, and stimulated with confined cyclic or static compressive stresses for 24 and 72 h. Compression stimulation resulted in a significant increase in proliferation, invasive morphology, and chemoresistance. Additionally, CDC42 was upregulated in compression stimulated conditions, and was necessary to drive increased proliferation and chemoresistance. Inhibition of CDC42 lead to significant decrease in proliferation, survival, and increased chemosensitivity. In summary, the dynamic in vitro 3D platform developed in this report, is ideal for understanding the influence of compressive stimuli, and can be widely applicable to any epithelial cancers. This work reinforces the critical need to consider compressive stimulation in basic cancer biology and therapeutic developments.

This study examines the impact of the corporate diversification strategy on the stock price crash risk. Using a large sample of Chinese A-share listed companies for the period 2003-2017, we find the stock price crash risk significantly increases when the operation strategy of a firm changes from a specialized operation to a diversified operation or the degree of diversified operations deepens. We also find that our results are stronger for non-state-owned listed firms, but not significant for state-owned firms. Furthermore, we find that the significant positive association between diversification and crash risk is more pronounced for firms with low external audit quality and low analyst coverage. Our study suggests that the diversification of operating strategy matter in determine stock price crash risk.

In recent years it has been recognized that embedding information in wavelet transform domain leads to more robust watermarks. In particular, several approaches have been proposed to address the problem of watermark embedding combined to wavelet based image coding. In this paper, we present an alternative to quantization based blind watermarking strategy in the framework of JPEG2000 still image compression. The central contribution is the proposal of modified Quantization Index Modulation watermark design to reduce fidelity problem. We also show that the proposed watermarking scheme exhibits a high robustness with respect to JPEG2000 compression and Gaussian noise attacks. After detailing the proposed solution, system performance on image quality as well as robustness will be evaluated.

Two new assumed stress membrane finite element families with two translational and one rotational degree of freedom per node are presented. The families, denoted by 8β(M) and 8β(D), are rank sufficient and invariant, and are derived using a unified Hu–Washizu like variational formulation. A recent stress mode classification method is used to illustrate the construction of the stress interpolation matrices. In each family, a number of new formulations are derived. Numerical results are presented. Copyright © 2001 John Wiley & Sons, Ltd.

The aim of this work was to present iterative learning tracking control of a hybrid-driven based three-cable parallel manipulator (HDCPM). The HDCPM has the advantages of both cable parallel manipulator and hybrid-driven planar five-bar mechanism. Design of the HDCPM is described and dynamic model is developed on the basis of Lagrange method. Consider the HDCPM system with nonlinear, time-varying characteristics and repetitive unknown disturbances; an adaptive iterative learning control strategy, which can control gains change with the iterations, is designed. By means of Lyapunov function, the stability of the controller is proved. Finally, simulation results indicate that a perfect trajectory tracking of the HDCPM is achieved by the adaptive iterative learning controller, which also illustrate the correctness of the dynamic modeling and effectiveness of the proposed control strategy.

There have been numerous case studies of prison graffiti produced in the Spanish Empire. Most publish archaeological finding; only a few approach them as historical testimony that may provide a series of information about those who produced them and the times they lived in. However, none have undertaken an overview covering all the territories held by the Spanish crown during the 16th-18th centuries. This paper aims to do by piecing together the evidence collected to date in order to draw some general conclusions about the reasons that drove prisioners to write and draw on the walls of their prisons

ago, when I began to realize that the reality of what we, for good or bad, call “globalization” was fundamentally changing the problems of freedom of speech and press. The increasing interconnectedness of the world was having a profound impact on individual nations while creating issues and challenges that required collective action at a global level. The nearuniversal embrace of some version of capitalism and open markets, the easing of barriers to the movements of people, and the emergence of the first ever truly global communications system (led, of course, by the Internet, but preceded and supported by satellite broadcasting and other forms of communication) together augmented trends toward integration of the world that, in turn, would reshape how we communicate and need to communicate in order to cope with a new level of shared life.1 Climate change, economic bubbles, recessions— and, yes, pandemics— would offer undeniable proof that global discussion of global issues was more and more the order of the day.2 But it was also increasingly apparent that this new world required a different level of political structure or framework. The international institutions established in the wake of World War II needed to be refreshed or replaced.3 Life Preface

Background: Despite an aggressive treatment regime, 40% of patients with high-risk neuroblastoma die of their disease. The mitogen-activated protein kinase (MAPK) signaling cascade is hyperactive in many cancers, including a subset of high-risk neuroblastomas. We, therefore, sought to determine the efficacy of MEK inhibition in neuroblastoma and develop a responder hypothesis of anti-tumor activity based on molecular genetic features. Methods: MEK162 (Novartis Pharmaceuticals), an orally available MEK1/2 inhibitor, is currently in adult clinical trials for advanced malignancies harboring RAS/RAF mutations. In determining MEK162 IC50 values, we employed the RT-CES cell impedance assay as it measures both cytostatic and cytotoxic responses in a temporal manner. Additional in vitro analysis of MEK162 activity included immunoblotting, cell cycle analysis with flow cytometric methods, and phosphorylation arrays across a panel of 23 neuroblastoma cell lines. Four of these cell lines (2 sensitive and 2 resistant) were also tested in vivo in subcutaneous xenograft models with tumor volume endpoints. The cell line IC50 ranking was cross-referenced with HuGene1.0ST expression microarrays (Affymetrix), phosphorylation arrays (Full Moon Biosystems), and exome sequencing in order to identify the genetic and proteomic underpinnings predictive of response to MEK inhibition. Microarray analysis was performed using the Limma package (Bioconductor/R), unsupervised clustering, and gene set enrichment (GSEA). Results: Neuroblastoma cell lines (N=23) showed a wide range of sensitivity to MEK162 across a 4-log dose range (median IC50 = 771 nM, range 5 nM-10 μM). Sensitive cell lines demonstrated G1 arrest within 24 hours of exposure to MEK162. In vivo subcutaneous xenograft experiments recapitulated the in vitro response of MEK162 sensitivity in each of the cell lines tested. In order to identify determinants of sensitivity, we profiled the genomic signature of 23 cell lines in the exponential growth phase prior to confluence. Of the ten most sensitive cell lines, six possessed mutations predicted to be damaging and indicative of RAS/MAPK pathway hyperactivation (NRAS-Q61K, NF1 copy number loss, KRAS-G12D). No resistant lines possessed genetic evidence of RAS hyperactivation. However, baseline phosphorylated-ERK status was not robustly predictive of drug activity. For the purpose of biomarker discovery, we considered a total of 4 cells lines as sensitive (IC50 3,000 nM). Unsupervised clustering and GSEA of the most differentially expressed genes derived from comparing sensitive (N=4) and resistant (N=4) cell lines confirmed increased baseline MAPK pathway activity in the sensitive cell lines. In addition, resistance to MEK162 was found to be associated with MYCN expression (R=.70/p=0.00043), suggesting that MYCN may serve as a biomarker of MEK162 resistance. Independently, we have demonstrated a correlation between MYCN-amplification and sensitivity to CDK4/6 inhibition (p=0.0227), suggesting the combination of MEK and CDK4/6 inhibition may synergize in the inhibition of neuroblastoma growth. Conclusions: MEK inhibition is effective in a definable subset of human-derived neuroblastoma preclinical models. Canonical activation of the RAS/MAPK pathway via RAS mutation and/or NF1 inactivation partially account for sensitivity to MEK inhibition, however, biomarkers predictive of sensitivity to MEK inhibition remain to be identified. We demonstrate that both MYCN expression and CDK4/6 activity are associated with MEK resistance, providing a basis for defining MEK162 combination strategies in the treatment of neuroblastoma.

OBJECTIVES
This study tested the directionality of the association between sleep and health outcomes in youth with asthma.
METHOD
Thirty-eight youth with asthma (aged 9-19) completed a daily diary study on sleep, asthma symptoms, peak expiratory flow (PEF) measures, and salivary cortisol samples.
RESULTS
Greater quantity of sleep predicted lower PEF% [beta(32) = -.33, p =.02], and lower daily cortisol output [beta(33) = -.31, p =.07] the following day. Additionally, poorer self-reported sleep quality predicted more severe symptoms the next day [beta(33) =.27, p =.05]. In contrast, PEF%, cortisol, and asthma symptoms did not significantly predict self-reported sleep quantity or quality the next night.
CONCLUSIONS
Results suggest that sleep may affect subsequent health outcomes, rather than asthma impacting subsequent sleep, indicating the potential benefits of targeting sleep behaviors in youth with asthma.

The biomedical model of disease, though powerful, does not explain all known facts about cancer. It is argued that a broader theoretical framework which includes psychosocial factors is needed. There is empirical evidence that a hopeless/helpless coping style is associated with unfavorable disease outcome in patients with certain cancers. The converse, namely a link between an active, fighting spirit coping style and favorable disease outcome, is under-researched and less clear-cut. The delineation, measurement and psychophysiology of positive states of mind have been sorely neglected. This is a promising area for future research. Psychobiological mechanisms of possible relevance to cancer are considered in terms of psychoneuroimmunology. Despite formidable theoretical and methodological problems, some progress is being made. Recent evidence indicates that psychotherapeutic intervention can augment natural killer cell activity and lymphokine-activated killer cell activity in patients with malignant melanoma and with locally advanced, nonmetastatic breast cancer respectively. These challenging findings, if confirmed, have major implications for our understanding of mind-body interactions in patients with cancer.

The term “executive function” has been used to describe several higher-order cognitive processes. This study examined the processing speed, shifting, planning, and verbal fluency of a sample of 50 Portuguese children with developmental dyslexia (DD) and 50 typically developing children (TDC; chronological-age-matched controls) between 8 and 12 years of age to evaluate the children’s executive functioning. Compared to TDC, children with DD revealed significant processing speed, shifting, and verbal fluency deficits. After controlling for differences in the general intellectual ability, significant group differences remained for shifting, verbal fluency and marginally for processing speed. No significant differences in planning ability were observed between the groups. No significant interaction of group, gender, and age was found for any of the executive functions measures studied. Word productivity in both semantic and phonemic verbal fluency tasks decreased significantly over the 60 seconds for both groups. Shifting was the only significant predictor of DD in the binary logistic regression analysis and yielded the highest area under the curve value (receiver operating characteristics curve analysis). Therefore, although these findings highlight the presence of specific executive functions deficits in children with DD, they should not be interpreted as indicative of the presence or absence of this learning disorder.

ABSTRACT Objective: To estimate the smoking cessation rate and to identify possible associated factors. Methods: Individuals from the Metropolitan Region of Belo Horizonte (MG) aged 15 years or more who responded to the smoking supplement of the National Household Sample Survey were selected (n=1,297). An estimate was made of the tobacco-use cessation rate relative to the 95% confidence interval. To verify factors associated with smoking cessation, Pearson's χ2 test or Student's t test were used. Results: The general smoking cessation rate was 56.7% (95% confidence interval: 52.3-61.1), with 57.7% among men and 55.5% among women. The associated factors were higher age and income. Among the 19 individuals who had stopped smoking for less than 12 months, 52.6% had been seen by a physician or healthcare professional in the previous 12 months, and 60% of them were oriented to stop smoking, but only 1 (16.7%) had been oriented at a unit of the public national Unified Healthcare System. Conclusion: Despite high rates of smoking cessation, the methods made available by the Unified Healthcare System did not show good results. It is necessary to enhance the healthcare programs that aim to reduce the proportion of smokers in the population. Such measures can have a positive long-term influence in droping mortality and morbidity rates associated with smoking and the costs for healthcare services.

tion of a lipoid solvent, such as ether, the lipoids would be temporarily changed in their physical condition. Under this changed physical condition, the metabolism of the cell would be arrested. If under these circumstances a dye be brought into the tissue fluids, a more or less permanent impregnation of the lecithin in the cell envelop would result. Pharmacologists will no doubt ascertain whether these data cannot be put to practical use in pathological disturbances of certain groups of cells. It will first of all be necessary to determine whether the anchoring of the dye or analogous compound to the cell membrane leads to a damage to its normal permeability after the solvent has been removed. • SOME INVESTIGATIONS IN LOBAR PNEUMONIA.

Spectral Angle Mapper (SAM) model has got wide applications in hyperspectral Remote Sensing (RS) information processing. But Spectral Angle couldn't achieve satisfied performance in some cases because of its sensitivity to noises and uncertainty. Based on the analysis to traditional SAM algorithm, four types of errors and their impacts to spectral angle are investigated. In order to reduce the impacts of above errors, some improved algorithms are proposed and experimented. The first improved algorithm is grouping spectral angle algorithm. In this new algorithm all bands are divided into two sets by odd and even bands, that means two additional sub-vectors are created in addition to the original spectral vector. So three spectral angles will be computed and the minimum of three indexes is used as final index. The second improved algorithm is normalized spectral angle. In this way spectral angle is computed to the normalized vectors of two original vectors. Two approaches are used to normalize the spectral vector, and spectral angle is computed to the normalized vectors. This algorithm is able to decrease the impacts of random errors. The third algorithm is intersected spectral angle. Spectral angle is calculated by a spectral displacement strategy in this approach. That means a given displacement to change the corresponding bands of two spectral vectors is used and a spectral angle to the displaced vectors will be got. By this displacement strategy the impacts of band offset is reduced. Finally some experiments are used to test those improved algorithms. It proves that those new approaches can reduce and control the errors and improve the precision and reliability of similarity measure.

Globalization in this 21st century unifies nations. The globalization impacts positively to promote trade and services among the nations but it could also harm economic growth and technological innovations in nations as their capital are drained to elsewhere. On its own merits, the globalization is a true manifestation of an open economy. The medical profession is not immune to this phenomenon: globalization. Mainly for the sake of affordability, many patients in much advanced nations, often voluntarily, seek medical services in far less underdeveloped nations. In other times, some patients are incited by their health insurance industries to practice medical tourism. The medical tourism creates an economic turmoil. Several medical economists are quite puzzled by the advantages as much as by the damaging impacts by the booming popularity of the medical tourism. It is time that all consequences of the medical tourism are examined in details as the findings would benefit the patients, the health policy makers and health industries. Such are the aims of this article. This article applies a data mining approach to compute and interpret economic indices, in a novel manner, to portray the economic booming in the hosting nations which render the medical treatments to the patients who emanate from the guest nations. Using the variations in the medical tourism data, a principal components analysis is performed to group the medical treatments and separately to group the hosting nations in terms of their closer proximities. According to the principal component analysis of the medical tourism data, there are three groups of nations which provide the treatments. The first group consists of USA, Columbia, Costa Rica and Nicaragua. The second group consists of India, Israel and South Africa. The third group consists of Jordan, Thailand and Malaysia. Also, an analysis of variance is performed to assess the significance of the factors on the cost of the medical treatment. Performing likewise on the type of the medical treatments which the medical tourists seek, there are three groups. The first group consists of medical treatments: heart by-pass, angioplasty, heart valve replacement, hip replacement, hip resurfacing, knee replacement, spinal fusion, gastric sleeve and gastric by-pass and lap band and liposuction and ivy treatments. The second group consists of tummy tuck, breast implants, rhinoplasty, facelift, hysterectomy, cornea and retina. The third group consists of dental implant and Lasik eye-surgery. The analysis of variance reveals that the nation Israel differs significantly from the hosting nations Columbia, India, Jordan, Malaysia and South Africa. The nation India differs significantly from the hosting nations South Korea. Furthermore, the Gini’s index of heterogenity and entropy index of heterogenity are computed as these indices capture the cost data volatility. These indices are then standardized and interpreted. Among the nations from which the medical tourists seek treatment in other nations, the nation USA emerges to the top in the list while Israel, India, South Korea and Thailand are emerging to the top in the list for treatments by the medical tourists. Interestingly, the cost differences among all other nations are not significantly different. The medical tourists concentrated on nations: India, Malaysia, Columbia and Mexico in its descending order of importance for the medical treatments: heart bupass, ental impant and liposuction in its descending order.

Recently, we introduced a bidirectional Fano algorithm (BFA) [10] which can achieve much higher decoding throughput compared to the regular unidirectional Fano algorithm (UFA), especially at low signal-to-noise-ratio (SNR). However, the decoding throughput improvement of the conventional BFA with respect to the UFA reduces as the SNR increases and converges to 100% at high SNR. In this paper, two parameters in the BFA, which are known as the number of merged states (NMS) and the threshold increment value Δ, are exploited to improve the decoding throughout of the conventional BFA. The improved BFA can achieve much higher decoding throughput compared to the UFA and the conventional BFA, especially at high SNR. For example at Eb/N0=5dB, the throughput improvement achieved by the improved BFA is about 280% compared to the UFA and about 80% compared to the conventional BFA, and its computational complexity is only 4% of the Viterbi algorithm.

A novel, nitrate-free, combustion method has been developed to prepare Ni–BaZr0.85Y0.15O3−δ (Ni–BZY) cermet anodes for proton ceramic fuel cells. Nickel acetate and 30% H2O2 were used as starting precursors for the combustion reaction into which pre-prepared BZY powders were dispersed. The advantages of this nitrate-free combustion method have been demonstrated by comparison to a more common nitrate/glycine combustion route. The results demonstrate that use of the nitrate-free precursors is essential to avoid partial decomposition of the pre-prepared BZY phase. Employment of the more common nitrate-based precursors, due to their acidic nature, results in removal of Ba from the perovskite phase and formation of Ba(NO3)2, subsequently leading to the presence of BaY2NiO5 in the final product. The impact of Ni–BZY phase purity on resultant polarisation behaviour has been assessed as a function of water vapour and oxygen partial pressures for electrodes of comparable microstructure. Partial decomposition of the perovskite phase limits performance by increasing the higher frequency polarisation resistance and this phenomenon is suggested to be associated with impaired proton transport in the oxide cermet phase. The novel actetate–H2O2 combustion method here described may be of interest for the formation of other ceramic oxide materials, offering economical advantages over more classical nitrate-based combustion routes, as well as significant environmental benefits due to the avoidance of releasing NOx gases.

A completely infarcted lymph node is an unusual event. However, lymph node infarction should alert the pathologist to the considerable likelihood of malignant lymphoma. We report two unusual cases of acute myeloid leukemia presenting with granulocytic sarcoma at disease onset with a lymph node lesion exhibiting extensive lymph node infarction. The infarcted tissue contained numerous eosinophilic cell ghosts. There were some islands of degenerated, pyknotic medium‐sized nuclei resembling lymphoblasts present in the necrotic area. By immunohistochemistry, these medium sized cells were CD3−, CD20−, CD34+, CD43+, CD45RO−, CD68−, CD79a− and myeloperoxidase+ in both cases. Differentiation of granulocytic sarcoma from malignant lymphomas is important for adequate therapy. The present cases indicate that granulocytic sarcoma should be added to the list of differential diagnoses for lymph node infarction.

The article reviews career guidance as a support mechanism for professional education and considers it as a necessary tool to choose the right career. The need of providing advisory service to young people and adolescents regarding professional guidance, identifying strengths and weaknesses, realizing one’s interests and inclinations may arise at various stages of life: after the completion of basic level, finishing secondary school, starting a professional career, changing a job, career planning, starting a family, unemployment. In each of these situations young people and adolescents may need help from professional consultants. Within the scope of the article secondary and tertiary level students and parents from Georgia have been surveyed. The questionnaires were designed to identify students’ and parents’ attitudes towards professional orientation classes, how they evaluate the importance of career guidance at school, which grades they consider most suitable for professional orientation classes. The survey attempts to find out who gives advice to Georgian secondary-level students when making career choices from students’ and parents’ perspectives. Tertiary level students were also surveyed in an attempt to find out what or who influenced them when choosing careers and to evaluate their satisfaction with their decisions. It also looks at the level of parents’ involvement in the implementation of professional guidance at schools. Through the analysis and processing of qualitative questionnaires we summed up the main challenges and problems that hinder making meaningful career choices. The article draws up some conclusions and recommendations important for Georgian environment.

The Skills, Knowledge, Aptitude, and Attitude (SKA) Subcommittee of the National Commission on Veterinary Economic Issues (NCVEI) has identified the need for veterinary teaching hospitals (VTH) to be at the forefront of progressive business management to serve as a model for both students and practitioners to emulate. To provide a foundation for developing a model, this study reviewed pertinent literature applicable to the management of a VTH. Much of the literature relevant to VTH management relates to work completed for the human side of medicine (academic health centers, or AHCs) or to the private sector. This review explores management practices in strategic planning, financial management, human resource management, marketing, pricing, operations, and legal issues. It is concluded that strategic management is important to provide the foundation for success in the VTH. In addition, periodic financial reports are recommended, as are the development and use of benchmarks for financial management. Establishing positive, motivating human resource practices is also suggested, along with development of a marketing plan based on a clear understanding of VTH core competencies and the market's specific needs.

Introduction The possibility of "out-growing" atopic disorders, especially asthma, at puberty is of great importance to the patient, his family, and the physician. There is widespread clinical agreement that some allergic manifestations which begin in childhood occasionally disappear in adolescence. How often this occurs is unknown. Certain difficulties have impeded past attempts to obtain valid information concerning allergic manifestations. The prevalence of major atopic diseases among children remains unknown, although they are estimated to occur in 7%-24% of all children in the United States. 1-4 Ten per cent is the figure frequently quoted. 1 Data on the prevalence and progression of asthma, as well as other atopic disorders, in adolescent subjects are lacking. Before determining the course of atopic disorders in adolescence it was necessary to establish their prevalence and nature in an adolescent population. This study was a prevalence survey of major allergic diseases—asthma, hay fever, perennial allergic rhinitis,

A particle swarm optimization (PSO)-based automatic system to determine the number of optimal band sets and corresponding bands is proposed. A simple searching criterion function, called minimum estimated abundance covariance (MEAC), requiring class signatures only, is used in this method. The experimental results show that the PSO-based algorithm outperforms the popular sequential forward selection (SFS) method. The two PSOs can achieve the balance between the two objectives, and it may provide even better accuracy than a single-objective PSO.

Goalball has been highlighted as a reference disabled sport from educational levels to its participation in the Paralympic Games, where the effects of this sport on balance and its relevance have been investigated. The aim of the systematic review was to systematically review those studies that evaluated the effects of goalball on balance in goalball athletes. A systematic review of PubMed and FECYT (Web of Sciences, CCC, DIIDW, KJD, MEDLINE, RSCI, and SCIELO) was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The articles were included if they met the following inclusion criteria: (i) participants were goalball players; (ii) athletes playing goalball; (iii) outcomes were related to balance; and, (iv) original articles without language restriction. From the 85 studies initially identified, 7 were fully reviewed, and their outcome measures were extracted and analyzed. In conclusion, the levels of balance seem to be closely related to the success of competitions, leading coaches to consider its development during training sessions. In this sense, the general practice of goalball may be sufficient at children’s levels, while the practice of 2 days or 5 h per week seems to be an adequate reference. However, athletes with partial levels of visual loss should not be subjected to continuous blinding during training sessions because it could lead to an accelerated reduction in balance levels.

The current pandemic has demonstrated a lot of weak links in the social and economic fabric of the society. Addressing these issues is paramount to enable any successful discussion of smart city technologies. The health inequity and accompanying problems faced by the disabled community during the pandemic underlined that our current systems are not built for resiliency. it is important for us to understand what has been done towards solving this complex problem and where we could further allocate our resources to tackle this issue.

Students who are deaf or hard-of-hearing (DHH) struggle to attain grade-equivalent literacy skills and require education interventions to improve. Recent literature reviews have revealed the need for high-quality intervention research for the following areas of reading: vocabulary development, reading comprehension, reading fluency, and grapheme–phoneme correspondence. The purpose of the current study was to determine the evidence surrounding morphological development for students who are DHH. The results were reported in a table as well as descriptively. This population exhibits a morphological knowledge delay that may be improved through explicit morphological instruction. Future researchers should consider conducting high-quality morphology intervention research with students who are DHH.

We consider a stochastic model of infection spread on the complete graph on $N$ vertices incorporating dynamic partnerships, which we assume to be monogamous. This can be seen as a variation on the contact process in which some form of edge dynamics determines the set of contacts at each moment in time. We identify a basic reproduction number $R_0$ with the property that if $R_0 1$ the infection survives for an amount of time $e^{\gamma N}$ for some $\gamma>0$ and hovers around a uniquely determined metastable proportion of infectious individuals. The proof in both cases relies on comparison to a set of mean-field equations when the infection is widespread, and to a branching process when the infection is sparse.

Fitness effect of spontaneous mutations accumulated in mismatch‐repair deficient strains of yeast was estimated by measuring their maximum growth rate. Several environments with different energetic substrates, nutritional conditions, and temperature were tested. Genetic load of haploid strains was about 20–30% under most of these conditions. Because such a pronounced effect was caused by relatively small lesions (point mutations) affecting probably less than 1% of genes, resistance of the yeast genome to DNA damage appears to be rather limited. Fitness transitions among environments were orderly, in the sense that some strains tended to be more or less fit than others in all circumstances. One of the environments (an extremely high temperature, 38°C) was stressful to the strains that accumulated mutations, as some of them stopped to grow, whereas the mutation‐free strains were only moderately affected. These results imply that the impact of random point mutations is substantial and generally not dependent on a particular environment. Under stressful conditions, however, natural selection may be especially effective in purging mutations that, if commonly met, could slow down the rate of mutation accumulation.

This paper presents an efficient multibody methodology for the simulation of molecular dynamics of simple polymer chains. The algorithm is formulated in terms of absolute coordinates. The augmented Lagrangian method is incorporated into the divide and conquer framework giving new parallel, logarithmic order algorithm suitable for the simulation of general multibody system topologies. The approach is robust in case of potential rank deficiencies of the Jacobian matrices that embrace the group of systems involving redundant constraints, and which may repeatedly enter singular configurations. Series of nanosecond-long molecular dynamics simulations of simplified polymer chain models are performed to demonstrate the correctness of the methodology and investigate the structure formation of the system subjected to non-bonded (Lennard–Jones) and bonded (torsional) interactions. Conformational changes and dynamic properties of the polymer chains are studied under gradual cooling of the system. The simulation results show that some of the homopolymers collapse into well-formed helices. The fraction of the succeeded runs, in which defect-free helices are found, is a function of initial conditions, chain length, and cooling rate. The employed computational multibody approach appeared to be useful in molecular dynamics simulations implying potential for future research and further development in this field.

Inhibitory CD4+ T cells have been linked with suboptimal immune responses against cancer and pathogen chronicity, but the mechanisms that underpin the development of such regulatory networks in vivo have remained obscure. To address this knowledge gap, we performed a comprehensive functional, phenotypic, and transcriptomic analysis of IL-10-producing CD4+ T cells induced by chronic infection with murine cytomegalovirus (MCMV). We identified these cells as clonally expanded and highly differentiated TH1-like cells that developed at sites of viral persistence in a T-bet-dependent manner and coexpressed arginase-1 (Arg1), which promotes the catalytic breakdown of L-arginine. Mice lacking Arg1-expressing CD4+ T cells exhibited more robust antiviral immunity and were better able to control MCMV. Conditional deletion of T-bet in the CD4+ lineage suppressed the development of these inhibitory cells and also enabled better immune control of MCMV. Collectively, these data elucidated the ontogeny of IL-10-producing CD4+ T cells and revealed a previously unappreciated mechanism of immune regulation, whereby viral persistence was facilitated by the coexpression of Arg1.

An analysis of the results of complex experimental and theoretical studies of photoinduced changes in the spectral properties of photochromic diarylethene in various nanostructured systems is presented. The properties of diarylethene were studied in solutions in the presence of colloidal metal and semiconductor nanoparticles, as well as in the form of solid-phase composite nanostructured core-shell systems based on colloidal nanoparticles with a shell of diarylethene molecules (including in a polymer matrix). A photoinduced reversible change in the electronic and vibrational spectra of diarylethene in various studied matrices was found. The results can be used to create optoelectronic photo-switchable elements for ultra-high-capacity memory devices, photo-controlled molecular switches and sensors.

This paper introduces a new method for the characterisation of the boundary of diffuse and local necking based on DIC measurements during tensile tests. A series of images illustrate the extension of diffuse necking and show the occurrence of local necking as well. The evaluation of strain distribution gives the exact description of processes using both time dependent and non-dependent methods.

Capsule endoscopy is becoming an important tool for diagnosis in the digestive system. In certain parts of the gastrointestinal tract, such as the stomach, the capsule should be self-propelled. This study examines the swimming mechanism for a miniature gastric pill endoscope. Our method is based on a constant external magnetic field, such as the B0 field of an MRI (Magnetic Resonance Imaging), that drives a pair of coils in order to create an undulating swimming motion. We present a dynamic model of the two coil swimmer and compare it to the results obtained using PIV (Particle Image Velocimetry). We demonstrate that our swimmer is able to create an average propulsive force of 0.03 mN and 0.07 mN for the flow regimes tested, which is in a reasonable agreement with the results of the proposed dynamic model.

The surface flaw of a drawn wire has a significant influence on the quality of a product. High-surface-quality drawn wires and rods have been required for the manufacture of automobiles and machines. Wire breaks due to large surface defects are common problems in wire drawing. The authors carried out rolling and multi-pass drawing of a stainless-steel wire with an artificial scratch, and investigated the growth and disappearance of a scratch from both sides by experiments and Finite Element Analysis (FEA). When the scratch angle is small, the scratch side surfaces are pushed toward each other and the scratch becomes an overlap defect. In contrast, when the scratch angle is large, the bottom of the scratch rises, and the scratch is recovered satisfactorily. Furthermore, the scratch shape and the drawing conditions were varied, and the deformation state of a scratch was clarified.

Novel self-assembled V2O5 bundles with highly ordered superstructures and spindle-like morphology were synthesized by a rapid high-yielding sonochemical method. The as-prepared samples were characterized by X-ray diffraction, a field-emission scanning electron microscope, and a transmission electron microscope. The spindle-like V2O5 bundles are composed of several tens of homogeneous nanowires with diameters of 30-50 nm and lengths of 3-7 microm. A sensitive resonance light scattering method for the detection of bovine serum albumin (BSA) based on the self-assembled V2O5 bundles was developed. The results of the polarized resonance light scattering demonstrated that the Cabannes factor for the V2O5 bundles-BSA aggregates was BSA concentration-dependent.

The impact of extreme weather on maintaining flight schedules is becoming more pronounced. Currently, radar echo extrapolation technology is widely used in the nowcasting of severe convection, in which the optical flow method is a representative example of traditional extrapolation algorithms. By training a large number of known samples to find the optimal solution, the deep extrapolation models have gradually become better than the traditional algorithms in recent years. In this study, after examining the optical flow method and other deep learning models, a learnable optical flow deep model with a fully convolutional structure is proposed. Using the convolutional deep learning of optical flow information, this new model can overcome the kernel size limitation of traditional convolutional neural networks, and it can correlate the data history further in time and space. The six-year radar mosaics of Guangdong Province, China, were used as the data set to independently train and verify the new model. The results reveal that the new model outperformed the traditional optical flow method and it is also better than other deep learning models.

The combination of rehabilitation technologies and better control systems for the assistive technologies allows us to create brain-machine interfaces for motion control by using exoskeleton devices. In this work, the creation of a protocol and analysis method is developed for human decision-making decoding in tasks related to motor activity. The aims of this research is to be able to develop a real-time interface for the control of a lower-limb exoskeleton in the future. The proposed analysis tries to decode the patterns when subjects have the intention to change their current speed on their own will. 4 subjects performed the experiments obtaining results around 65%.

For reliable on-body communications, the antennas involved need to meet certain requirements such as minimal frequency de-tuning and minimal efficiency degradation. The textile antenna has emerged as a promising candidate for the role in on-body communications but its performance characteristics have not yet been adequately treated in literature; particularly so in the on-body scenario. In a recent investigation into small-sized textile antennas, the authors remarkably determined that a lossier free-space antenna could outperform an antenna with higher free-space efficiency when placed on-body. The purpose of this study, therefore is to determine the practical on-body performance of two larger sized dual-band textile antennas using human subjects to see if this relation holds. The results show that a higher conductivity-based textile material in conjunction with a suitably large-sized ground plane performs more resiliently when placed on-body; about a 20% degradation in radiation efficiency is observed as compared with free-space levels, which is much less than the lower conductivity textile material in this study. The authors concur therefore that in addition to the conductivity of the textile material, the ground plane dimension is also of crucial importance in relation to how efficient the textile antenna performs on human subjects. The on-body frequency de-tuning of these antennas is also investigated, concluding that in the higher-frequency sub-band, both antennas remain well matched. However, detuning is apparent in the lower band, which should be taken into account when designing these antennas for on-body applications. Theoretical, simulated and experimental evidence is provided to verify the conclusions.

This article surveys the debate between “progressives” and “revisionists” about the Constitution and constitutional interpretation during the late nineteenth and early twentieth centuries. Contemporary revisionist scholarship assumes that its victory over progressive scholarship is complete. The article suggests otherwise. First, it summarizes the revisionists’ achievements. Second, in an attempt to improve the quality of the debate, it maintains that “revisionist” and “progressive” legal historians undermine their cases by using words like “progressive,” “Gilded Age,” and “Jacksonian,” and that “revisionist” is not an enlightening term, either. Third, it contends that revisionists have made straw men out of the progressives, whose diversity and contributions they ignore, and that they have shown a lack of empathy for the circumstances facing the progressives. At considerable risk, progressives called attention to the relevance of political calculation, economic self-interest, and biography to understanding the Constitution, constitutional interpretation, and judicial power. The article also observes that revisionists have not yet won the day and that there are still “progressive” holdouts in the legal academy and history departments. Finally, it argues that like the work of “revisionists,” the scholarship of the “progressives”—particularly if we rechristen both—still has something to teach us and that it is time to abandon the familiar dialectic of thesis and antithesis and turn to synthesis.

The International Maritime Organization (IMO), through its Maritime Environmental Protection Committee (MEPC), has been carrying out substantive work on the reduction and limitation of greenhouse gas (GHG) emissions from international shipping since 1997, following the adoption of the Kyoto Protocol and the 1997 MARPOL Conference. While to date no mandatory GHG instrument for international shipping has been adopted, IMO has given significant consideration of the matter and has been working in accordance with an ambitious work plan, with a view to adopting a package of technical provisions. Beside the efforts undertaken by IMO, it is assumed that optimized manoeuvring regimes have potential to contribute to a reduction of GHG emissions. Such procedures and supporting technologies can decrease the negative effects to the environment and also may reduce fuel consumption. However, related training has to be developed and to be integrated into existing course schemes accordingly. IMO intends to develop a Model Course aiming at promoting the energy-efficient operation of ships. This course will contribute to the IMO's environmental protection goals as set out in resolutions A.947(23) and A.998(25) by promulgating industry "best practices", which reduce greenhouse gas emissions and the negative impact of global shipping on climate change. In this paper, the outline of the research work will be introduced and the fundamental ideas and concepts are described. A concept for the overall structure and the development of suggested detailed content of the draft model course will be exemplarily explained. Also, a developed draft module for the model course with samples of the suggested integrated practical exercises will be introduced and discussed. The materials and data in this publication have been obtained partly through capacity building research project of IAMU kindly supported by the International Association of Maritime Universities (IAMU) and The Nippon Foundation in Japan.

Site-specific recombinases XerC and XerD function in the segregation of circular bacterial replicons. In a recombining nucleoprotein complex containing two molecules each of XerC and XerD, coordinated reciprocal switches in recombinase activity ensure that only XerC or XerD is active at any one time. Mutated recombinases that carry sub?stitutions of a catalytic arginine residue stimulate cleavage and strand exchange mediated by the partner recombinase on DNA substrates that are normally recombined poorly by the partner. This is associated with a reciprocal impairment of the recombinase's own ability to initiate catalysis. The extent of this switch in catalysis is modulated by changes in recombination site sequence and is not a direct consequence of any catalytic defect. We propose that altered interactions between the mutated proteins and their wild-type partners lead to an increased level of an alternative Holliday junction intermediate that has a conformation appropriate for resolution by the partner recombinase. The results indicate how subtle changes in protein-DNA architecture at a Holliday junction can redirect recombination outcome.

STUDY OBJECTIVE
To describe sleep characteristics and rapid eye movement (REM) sleep behavior disorder in patients with Guadeloupean atypical parkinsonism (Gd-PSP), a tauopathy resembling progressive supranuclear palsy that mainly affects the midbrain. It is possibly caused by the ingestion of sour sop (corossol), a tropical fruit containing acetogenins, which are mitochondrial poisons.
DESIGN
Sleep interview, motor and cognitive tests, and overnight videopolysomnography.
PATIENTS
Thirty-six age-, sex-, disease-duration- and disability-matched patients with Gd-PSP (n = 9), progressive supranuclear palsy (a tauopathy, n = 9), Parkinson disease (a synucleinopathy, n = 9) and controls (n = 9).
SETTINGS
Tertiary-care academic hospital.
RESULTS
REM sleep behavior disorder was found in 78% patients with Gd-PSP (43% of patients reported having this disorder several years before the onset of parkinsonism), 44% of patients with idiopathic Parkinson disease, 33% of patients with progressive supranuclear palsy, and no controls. The percentage of muscle activity during REM sleep was greater in patients with Gd-PSP than in controls (limb muscle activity, 8.3%+/-8.7% vs 0.1%+/- 0.2%; chin muscle activity, 24.3%+/- 23.7% vs 0.7%+/-2.0%) but similar to that of other patient groups. The latency and percentage of REM sleep were similar in patients with Gd-PSP, patients with Parkinson disease, and controls, whereas patients with progressive supranuclear palsy had delayed and shortened REM sleep.
CONCLUSION
Although Gd-PSP is a tauopathy, most patients experience REM sleep behavior disorder. This suggests that the location of neuronal loss or dysfunction in the midbrain, rather than the protein comprising the histologic lesions (synuclein versus tau aggregation), is responsible for suppressing muscle atonia during REM sleep. Subjects with idiopathic REM sleep behavior disorder should avoid eating sour sop.

Human beings need language as their communication because language as the branch of linguistic. When all people speak in a communication is a process and then, there must be both sender and receiver. Sometimes, all people only talk interaction not only directly interact and something more meaningless. In the branch of linguistics, semantic is the study about all the aspects of meaning outside the grammatical of language which different with morphology and syntax that concern with grammatical of language. In this paper, the writer interest to discuss about semantic analysis on lexical in Pujakesuma because semantics is one of the important aspect in linguistics and lexical of Javanese society nomads in Sumatera Utara (Pujakesuma) is also have different meaning to be analyzed.

Off-specular neutron reflectometry was applied to characterize the form and amplitude of lateral compositional variations at a buried reaction–diffusion front. In this work, off-specular neutron measurements were first calibrated using off-specular x-ray reflectivity and atomic force microscopy via a roughened glass surface, both as a free surface and as a buried interface that was prepared by spin coating thin polymer films upon the glass surface. All three methods provided consistent roughness values despite the difference in their detection mechanism. Our neutron results demonstrated, for the first time, that the compositional heterogeneity at a buried reaction front can be measured; the model system used in this study mimics the deprotection reaction that occurs during the photolithographic process necessary for manufacturing integrated circuits.

Coronary Heart Disease is a chronic disease with the highest morbidity and mortality rates in the world. Management is needed in the form of self-care management as a core element for CHD patients in order to improve the quality of life. Until now, there has been no comprehensive summary regarding self-care and quality of life for CHD patients with stents attached. This study aims to summarize research studies that link self-care and QOL in CHD patients after receiving Percutaneous coronary intervention. Systematic review using three databases (PubMed, ScienDirect, Google Scholar) for previous studies published in the last 10 years (2010–2020). The Joana Bright Institute format and PRISMA guidelines were used to assess the quality of studies and assist in the selection of articles. Data was extracted and summarized by the author using data extraction tools from JBI. Five articles from 2,729 studies were included. The results show inconsistency, namely three studies have a significant relationship and two studies have an insignificant relationship. All questionnaire domains used in the five articles state that the self-care domain of smoking cessation and exercise are correlated with the QOL domain of physical function, body pain, vitality, mental health, symptom domains and satisfaction. Only three articles reported the strength of the relationship (r = 0.117–0.64) and two articles didn’t report the strength of the relationship. By knowing self-care and QOL of CHD patients after receiving PCI, it’s hoped that the hospital can better understand and provide promotive/preventive education related to self-care management so that the patient’s QOL increases significantly.

Die 1,3-Dimethyl-1,3,2-diazaborolidine 3 – 6 addieren Aluminium- oder Galliumhalogenide im Molverhaltnis 1 : 1 zu Koordinationsverbindungen 3a – e, 4a, 5a, b, 6a, in denen der Ligand einzahnig ist. Die Anlagerung erfolgt unabhangig vom B-Substituenten an einem Ringstickstoff-Atom. Folge dieser Koordination ist die Ausbildung einer langen BN-Bindung zum chiralen tetra-koordinierten Ring-Stickstoff, eine erhebliche Verkurzung der BN-Bindung zum dreifach koordinierten endocyclischen Stickstoffatom und der Ubergang des nahezu planaren Funfrings in die „envelope”-Konformation, wie die Rontgenstrukturanalyse von 5a belegt. Im Gegensatz dazu liefert das 2-(Dimethylamino)diazaborolidin 7 mit AlX3 und GaX3 instabile 1 : 1- und stabile 1 : 2-Addukte 8. In diesen ist die Lewis-Saure nur an den Ringstickstoff-Atomen koordiniert.
Contributions to the Chemistry of Boron, 1351). Addition Compounds of 1,3,2-Diazaborolidines with Aluminium and Gallium Halides
1,3-Dimethyl-1,3,2-diazaborolidines 3 – 6 add aluminium and gallium halides, respectively, in a 1 : 1 molar ratio. The ligand is monodentate in these coordination compounds (3a – e, 4a, 5a, b, 6a). Addition occurs at one of the ring nitrogen atoms irrespective of the B-substituent. A consequence of this coordination is a long BN bond to the chiral tetracoordinated nitrogen atom as well as a considerable shortening of the BN bond involving the tricoordinate ring nitrogen. In addition, the almost planar five-membered ring adopts the envelope conformation as shown by an X-ray structure analysis of 5a. In contrast, the 2-(dimethylamino)diazaborolidine 7 yields unstable 1 : 1 besides stable 1 : 2 adducts 8. In these the Lewis acid is also coordinated to the ring nitrogen atoms only.

your average edited volume. The coverage is inevitably somewhat impressionistic and contributions vary between more general surveys (Thurlby, Weiss, van Houts) and detailed case studies (Rollason, Thomson, Gillingham, O’Brien). The present reviewer – who may reveal his own biases here – was particularly struck by the contributions of Crick and Vincent: both break substantial new ground, relating this well to the volume’s overarching themes. The former argues that later copies of pre-Conquest documents reveal a great deal about engagement with the early English past in the post-Conquest period. By focusing on imitative script – that is, when scribes consciously mimic the letter forms of their exemplars – she is able to show how monks and canons sought to bridge the gap between the preand post-Conquest worlds: by varying their letter forms they both showed a deep awareness of the gap which separated their world from that of the Anglo-Saxons and went some way towards bridging this. Long before the Renaissance and Enlightenment people were thus aware that the past was indeed a foreign country. Vincent, on the other hand, is able to show that Anglo-Saxon documents were surprisingly rarely presented to rulers of the twelfth and thirteenth centuries, a fact which raises significant further questions. In particular, it throws the active industry in forging pre-Conquest documents in later years in unusual light: if original documents were so rarely deployed in court or before the king, what good was a fake (however convincing)? In part, the answer lay in providing these documents with more ‘modern’ forms of authentication such as seals. In part, however, it reflects the caesura created by the Conquest; Vincent suggests that this was seen as a new point of departure, much as Bede had earlier envisaged the Adventus Saxonum: it rendered the more distant past of largely antiquarian interest. Still, it would be wrong to reduce this book to two contributions: there is much of interest to be found throughout, be it on the engagement with Anglo-Saxon law in the twelfth century (O’Brien), the use of purported viking attacks to explain gaps in institutional memory (Bartlett, Barrow), the construction of narrative histories of the Anglo-Saxon age (Rollason, van Houts, Gillingham), or the later interest in pre-Conquest saints and their cults (Love, Webber). The editors have done a fine job here. This volume will find a place on the bookshelves of all serious university libraries – and of many scholars too. We owe them our warmest thanks and congratulations.

Clinicians report reluctance to deliver opioid-tapering advice to patients with chronic pain, in part due to concerns that patients will be angry and dissatisfied. An experiment was conducted to examine chronic pain patients' emotional and attitudinal responses to simulated opioid-tapering advice. Patients scheduled for an initial assessment at a tertiary pain clinic and currently taking opioid medications for pain (N = 196) were randomly assigned to view video footage of a standardized patient receiving 1 of 3 forms of treatment advice: (1) stay on current medication (2) change to a different pain medication, or (3) taper off pain medications and participate in a CBT-based pain self-management program. Participants reported how positive/enthusiastic, anxious/worried, and angry/irritable they felt in response to the simulated treatment advice, and how satisfied with and willing they would be to accept and follow the advice. Participants expressed more positive emotional and attitudinal responses to simulated opioid-tapering advice than to simulated opioid-maintenance advice. Furthermore, participants' responses to simulated opioid-tapering and opioid-change advice were not significantly different, suggesting that participants responded positively to the prospect of change in treatment strategy. Additional analyses revealed that participants with a longer history of chronic pain and opioid use responded less positively to simulated opioid-tapering advice. The results of this study contribute to our understanding of factors that may shape chronic pain patients' responses to opioid-tapering advice and suggest that patients may respond more positively to opioid-tapering advice if it is presented together with an alternative treatment approach.

SUMMARY
Sex odor/flavor in pork was produced when fat, lean (with fat), and most organs from a boar were heated in a skillet or in boiling water. Odor seemed not to be entirely absent in boar fat at body temperature, although volatilization appeared to occur to a much greater extent at approx. 100–108° C. Sex odor was found to be water-insoluble, ether-soluble, and definitely associated with the fatty tissues of boars. It was absent in rehydrated moisture-free, fat-free lean. Distillation methods proved unsatisfactory for collecting the sex odor components in recognizable form, since no consistent and reproducible differences could be detected between boar and barrow fat when collected volatile compounds were analyzed by heat test and gas ehromatography. Cold saponification of boar fat yielded a small quantity of unsaponifiable matter that produced a concentrated, permeating sex odor on exposure to heat. Thus, the agent(s) responsible for sex odor in pork are located in the unsaponifiable material. Cholesterol and squalene were found in this fraction in both boar and barrow fat, but sex odor was not produced when these compounds were heated.

In the May of the third year of Chunhua (992) of the Northern Song dynasty, because of a long persistent drought and scorching hot day, the plague occurred and prevailed in Kaifeng, the capital of Northern Song, with a massive death toll, drawing much attention from the government. The cause of plague was related to high temperature, summer-heat warmth in TCM. In response to this, the government issued three imperial edicts: firstly, promulgating the formularies; secondly, sending some doctors to cure patient, as well as giving money and medicines. At the same time, the Imperial Medical Academy to preside over treatment and assigned an inner eunuch to be responsible for intendance; the third was sending the emissary to clear up the prison. This policies of the third year of Chunhua brought important effects to the system of prevention and rescue of epidemic disease in Song dynasty, exerting significant influences on the prevention and treatment of infectious diseases in the Song dynasty.

This paper shows how the mechanisms of endogenous growth can readily be incorporated within old growth theory, thereby resolving the principal impasse that stymied old growth theory. The key mechanism is the technological progress function which was originally developed by Kaldor (1957). The growth effects of monetary and fiscal policy operate through three channels. The first is the 'portfolio composition' channel, with policy serving to alter the money-capital mix of portfolios; the second is the money in the production function channel, with policy serving to alter the relative use of money and capital as inputs; the third is the money in the technological progress function channel, with policy affecting the dynamic allocative efficiency of investment via its impact on the level of financial intermediation. Since money and capital both enter the technological progress function, policies that affect the demands for money and capital affect the steady state rate of growth.

This paper presents a high-speed, broadband phase -locked loop (PLL) for RF transceiver in 65nm CMOS process. Programmable structures are used to improve the lock speed of the PLL, the charge pump and loop filter can be adjusted by digital bit to reduce locked time of PLL. An integrated voltage-control oscillator (VCO) with 75% tuning range and a high-speed divider are used to accomplish all the frequencies. To achieve a wide tuning range while keep a low gain and a low phase noise, the VCO uses switched capacitor array. Finally, the PLL realizes 6-12 GHz wide frequency coverage. The phase noise performance at 6GHz is -113dBc/Hz@lMHz. The layout area is only 0.5265mm2. Working at 1. 2V supply voltage, the power consumption of the circuit is 11.3432 mW. The lock time of the PLL after using AFC is about 15. 258us.

Background and Objectives The neuropsychological exam plays a central role in the assessment of elderly patients with cognitive complaints. It is particularly relevant to differentiate patients with mild dementia from those subjects with mild cognitive impairment. Formal education is a critical factor in neuropsychological performance; however, there are few studies that evaluated the psychometric properties, especially criterion related validity, neuropsychological tests for patients with low formal education. The present study aims to investigate the validity of an unstructured neuropsychological assessment protocol for this population and develop cutoff values for clinical use. Methods and Results A protocol composed by the Rey-Auditory Verbal Learning Test, Frontal Assessment Battery, Category and Letter Fluency, Stick Design Test, Clock Drawing Test, Digit Span, Token Test and TN-LIN was administered to 274 older adults (96 normal aging, 85 mild cognitive impairment and 93 mild Alzheimer`s disease) with predominantly low formal education. Factor analysis showed a four factor structure related to Executive Functions, Language/Semantic Memory, Episodic Memory and Visuospatial Abilities, accounting for 65% of explained variance. Most of the tests showed a good sensitivity and specificity to differentiate the diagnostic groups. The neuropsychological protocol showed a significant ecological validity as 3 of the cognitive factors explained 31% of the variance on Instrumental Activities of Daily Living. Conclusion The study presents evidence of the construct, criteria and ecological validity for this protocol. The neuropsychological tests and the proposed cutoff values might be used for the clinical assessment of older adults with low formal education.

In this article we use data covering 20 countries from the first round of the European Social Survey (ESS) collected in 2002-2003 to investigate how individual and contextual factors influence the subjective experience of economic strain among married and cohabitating men and women. Our main hypothesis is that countries with low labour force participation among women will tend to feature a gender gap in subjective economic wellbeing in the disfavour of female spouses/partners due to a negative association between labour force participation and economic strain at the individual level. However, we also present a secondary hypothesis about countervailing forces operating at the macro- level: in countries with a low aggregate labour force participation the economic wellbeing of women could be less dependent on own labour force participation because non-participation is supported by norms of income sharing within the household. We do find a strong negative association between own labour force participation and the subjective experience of economic strain, particularly among female partners, while we do not find consistent support for our secondary hypothesis about a negative interaction effect with high labour participation at the aggregate level.
