Le present article cherche a demontrer que le diagnostic des theoriciens du cinema annoncant la fin du 7e art — dans la mesure ou il reposerait sur le concept peirceen de l’index — fait foi d’une profonde incomprehension de la theorie semiotique de C. S. Peirce. En outre, les nouvelles images numeriques de la photographie et du cinema ne sont pas “moins” indexicales qu’avant et ne sauraient l’etre d’un point de vue strictement logique. Ce qui ne signifie pas, toutefois, qu’il n’existe aucune distinction pertinente au plan semiotique entre l’image photo-filmique d’une part, et la peinture, le dessin, ou l’image de synthese d’autre part. Nous ferons appel a la classification des signes elaboree par Peirce en 1903 pour examiner ce qui distingue ces deux paradigmes de l’image.

Abstract Transmission of information using elastic ultrasonic waves on existing metallic pipes provides an alternative communication option for a nuclear facility. The advantages of this approach consist of transmitting information through barriers, such as the containment building wall, with minimal modification of the existing hardware. Because bit rates on the order of kilobits per second are achievable, relatively large volumes of data, such as images, can be transmitted. A viable candidate for an ultrasonic communication channel is a stainless steel pipe of the chemical volume control system (CVCS) that penetrates through the reactor containment building wall through a sealed tunnel. To study ultrasonic communication under simulated nuclear facility conditions of high temperature, a test article was developed by installing heating tapes, temperature controllers, and thermal insulation on a laboratory CVCS-like stainless steel pipe. High temperature and radiation-resilient lithium niobate ultrasonic transducers were utilized for information transmission on the heated pipe. The amplitude shift keying (ASK) digital communication protocol was developed and implemented in a GNU Radio software–defined radio environment. A root-raised-cosine filter was introduced to suppress ultrasonic transducer ringing and thus reduce inter-symbol interference. This resulted in the enhancement of the data transmission bit rate compared to information encoding with square pulses. Demonstrations of communication at high temperature included transmission of a 90-KB image at the bit rate of 10 Kbps with a bit error rate of 10−3 across a 6-ft-long straight pipe heated up to 230°C. Additional preliminary studies were conducted to evaluate ultrasonic communication system resilience to environmental degradation and damage.

We have measured the surface impedance of Bi 2 Sr 2 CaCu 2 O 8 single crystals and have evaluated the conductivity σ 1 pvat millimeter-wave frequencies. We observe a peak below T c which we suggest is due to case-II coherence factors, like the Hebel-Slichter peak observed in the NMR relaxation rate of classical superconductors. A comparison with theory leads to a large gap, suggesting strong coupling

Localization of wireless devices is a crucial requirement for many emerging applications such as environmental monitoring, intelligent transportation, home automation, health‐care monitoring, and social networking. In this letter, we propose AWL a new aggregate weighted localization algorithm for mobile wireless networks. The proposed algorithm is distributed and requires low computational and communication overheads enabling its use in resource‐limited devices.

ABSTRACT Canonical babbling and volubility are common indicators of infant vocal development. If either indicator falls below values found in typical infants, it may be an early signal of a developmental disorder. The aim of this retrospective investigation was to examine home videos for the frequency of canonical babbles, age of canonical babbling onset, and overall volubility of eight infants later diagnosed with childhood apraxia of speech and compare these data to that of six typically developing infants as well as four infants later diagnosed with a speech sound disorder. Results revealed the infants later identified with childhood apraxia of speech used fewer canonical babbles, had later onset of canonical babbling, and fewer syllables per minute (volubility) than the comparison groups. These results suggest that infants later diagnosed with childhood apraxia of speech may be less adept in vocal exploration and in the production of canonical babbles, perhaps due to fewer opportunities for mapping articulatory movement with auditory speech sound outcomes.

The Grasscutter (Thryonomys swinderianus), is a wild herbivorous rodent peculiar to Africa. It is widely eaten in Nigerian rural communities as a protein source hence its domestication as microlivestock. There is paucity of data on the histochemical studies. This study was aimed at histochemically analyzing the stomach in order to determine if it exhibits regional differences in its qualitative expression of acid, neutral and carboxylated mucin. Seven animals obtained from the wild and domesticated in the animal house of the Department of Human Anatomy, Ahmadu Bello University, Zaria were used. Histologically, stomach of the Grasscutter was simple, glandular and composed of three regions: cardia, fundic‐body and pyloric. Cardia region showed enlongated tubular glands, coiled at the lower end with an opening continuous with the long conspicuous gastric pits. Fundic‐body region showed numerous gastric glands which open into fewer shorter gastric pits while the pyloric region showed simple tubular glands which are highly branched as such obscures the depth of the gastric pits. Histochemically, stomach of the Grasscutter exhibits regional polymorphism in the mucin content with the glands showing weak alcianophilic reactions. Cardia and pyloric regions demonstrated neutral periodic acid Schiff (PAS) reaction characterized by purple coloration thus indicating the presence of neutral mucins. Fundic‐body region exhibited strong PAS positive reaction particularly at the apical cytoplasm of the oxynticopeptic cells indicating the presence of carboxylated mucins. Results demonstrate that regional differences in the expression of mucins occur in the stomach of African Grasscutters, thus this may provide basic information for further nutritional and conservative studies.

Summary Possible enhancement by free fatty acids (FFA) of the arrhythmogenic actions of ouabain was studied in rabbits. The mean dose of ouabain required for inducing ventricular tachycardia or fibrillation in conscious animals was significantly lowered by intravenous injection of 5 ml of a 20% fat emulsion (Lipofundin), which significantly elevated circulating FFA. Lipofundin alone did not initiate arrhythmias in another group of animals. The transmembrane action potential duration (APD) and the maximum rate of depolarization (&OV0312;max) recorded from rabbit papillary muscles were markedly reduced under the influence of 2 mM octanoate, a short-chain FFA. Ouabain, 10−7M, reduced significantly only the APD measured at zero level of repolarization. In papillary muscles exposed to both octanoate and ouabain, resting potential, overshoot, APD, and &OV0312;max were all significantly decreased below control values. The synergistic arrhythmogenic actions of FFA and ouabain might be explained by the inhibiting effect of both agents on membrane (Na+ + K+)ATPase.

Edge computing (EC) has emerged as a key technology in future communication networks to enhance user experience and enable various Internet of Things (IoT) applications. In this paper, we propose an online framework for edge computing resource procurement in which a marketplace (platform) is established between sellers (i.e., resource contributors) and buyers (i.e., resource purchasers). Each buyer has a certain budget for his procurement campaign. The sellers arrive to the platform in an online fashion and offer their computing capacities along with prices that they want to be compensated for their services. Upon the arrival of every new offer, the platform has to make an irrevocable decision, without knowing future information, to accept the offer or not and to allocate the accepted resource to which buyer. We present an efficient online optimization method that helps the platform maximize the total system utility with guaranteed performance. Indeed, the developed model can be applied to other interesting settings such as edge caching and content delivery with slight modifications. Finally, numerical studies are conducted to illustrate the effectiveness of the proposed solution approach.

OBJECTIVE To demonstrate the performance and safety of a bihormonal (insulin and glucagon) artificial pancreas (AP) in adults with type 1 diabetes. RESEARCH DESIGN AND METHODS In this outpatient, randomized, crossover trial, 2-week fully closed loop glucose control (AP therapy) was compared with 2-week open loop control (patient’s normal insulin pump therapy with a glucose sensor if they had one). RESULTS A total of 23 patients were included in the analysis. Time in range (70–180 mg/dL [3.9–10 mmol/L]) was significantly higher during closed loop (median 86.6% of time [interquartile range 84.9–88.5]) compared with open loop (53.9% [49.7–67.2]; P < 0.0001). CONCLUSIONS Compared with insulin pump therapy, the bihormonal AP provided superior glucose control, without meal or exercise announcements, and was safe in adults with type 1 diabetes.

AIM: To assess the level of expression of TLR2, TLR4, TLR7 genes in the placenta and fetal membranes during full-term physiological pregnancy, without signs of onset of labor.
MATERIALS AND METHODS: The study was carried out at the premises of City Clinical Hospital No. 1 named after N.I. Pirogov (Samara), and included 15 pregnant women at 37-41 weeks of gestation without somatic pathology, exacerbation of chronic and acute inflammatory diseases, obstetric complications (placental insufficiency, preeclampsia). All patients were delivered by elective caesarean section due to fetal malposition. The level of expression of TLR2, TLR4, TLR7 genes was determined by reverse transcription and real-time PCR (RT-PCR) on the basis of the laboratory of NPO DNA-Technology using a set of reagents Proba NK.
RESULTS: The data on the features of TLR2, TLR4, TLR7 expression in the placenta and membranes during full-term pregnancy were obtained. Direct correlations were found between the production of TLR2, TLR4, TLR7 of the fetal membranes and TLR2 of the placenta. The expression of placental TLR4 and TLR7 was not associated with the production of the TLRs. Significant differences were revealed in pregnant women with inflammatory and involutive-dystrophic changes in the placenta and the level of TLR4 expression.
CONCLUSIONS: The expression of the Toll-like receptors (TLRs) in the tissues of the fetoplacental complex occurs uniformly during physiological pregnancy. There are positive correlations between the expression of TLR2, TLR4, TLR7 of the fetal membranes and TLR2 of the placenta, as well as its mass. The most significant indicator of the inflammatory process is the placental expression of TLR4.

Animal olfactory systems have a critical role for the survival and reproduction of individuals. In insects, the odorant-binding proteins (OBPs) are encoded by a moderately sized gene family, and mediate the first steps of the olfactory processing. Most OBPs are organized in clusters of a few paralogs, which are conserved over time. Currently, the biological mechanism explaining the close physical proximity among OBPs is not yet established. Here, we conducted a comprehensive study aiming to gain insights into the mechanisms underlying the OBP genomic organization. We found that the OBP clusters are embedded within large conserved arrangements. These organizations also include other non-OBP genes, which often encode proteins integral to plasma membrane. Moreover, the conservation degree of such large clusters is related to the following: 1) the promoter architecture of the confined genes, 2) a characteristic transcriptional environment, and 3) the chromatin conformation of the chromosomal region. Our results suggest that chromatin domains may restrict the location of OBP genes to regions having the appropriate transcriptional environment, leading to the OBP cluster structure. However, the appropriate transcriptional environment for OBP and the other neighbor genes is not dominated by reduced levels of expression noise. Indeed, the stochastic fluctuations in the OBP transcript abundance may have a critical role in the combinatorial nature of the olfactory coding process.

The hemodynamic responses to endothelin, a recently isolated vasoconstrictor peptide, were determined in conscious rats with and without the three major known neurohumoral control systems. Rats (n = 6) were instrumented with arterial and venous catheters and an electromagnetic flow probe around the ascending aorta. Neurohumoral blockade was achieved with 10 mg/kg chlorisondamine, 0.5 mg/kg methscopolamine, 1 mg/kg captopril, and 10 micrograms/kg d(CH2)Tyr5(Me)AVP. Resting mean arterial pressure (MAP), cardiac output (CO), and total peripheral resistance (TPR) in areflexic rats were restored to normal levels with a constant norepinephrine infusion. Endothelin was infused intravenously for 25 min in doses ranging from 0.01 to 1,000 ng.kg-1.min-1. Rats with intact reflexes did not respond significantly until a dose of 100 ng.kg-1.min-1 that increased MAP 20%, decreased CO 22% and increased TPR 58%. At a dose of 1,000 ng.kg-1.min-1 of endothelin (infused for 10 min), MAP increased 35%, CO decreased 66%, and TPR increased 303%. In areflexic rats, 1 ng.kg-1.min-1 of endothelin caused significant increases in MAP (14%), small decreases in CO (-5%), and a 20% increase in TPR. At a dose of 10 ng.kg-1.min-1, MAP increased 17%, CO decreased 3%, and TPR increased 21%; at 100 ng.kg-1.min-1, MAP increased 40%, CO decreased 13%, and TPR increased 67%; at 1,000 ng.kg-1.min-1, MAP increased 48%, CO decreased 61%, and TPR increased 319%. The pressor effects of endothelin were therefore significantly buffered by neurohumoral systems; however, the decreases in CO caused by high doses of endothelin were independent of neurohumoral control.

We evaluate the effect of natural resources on political regimes. We use the synthetic control method to compare evolution of the democracy level of countries affected by giant oil discoveries with the weighted democracy level of countries that do not incur the same event and have similar pre-event characteristics. Focusing on 12 countries affected by the peak of oil discovery from the 1970s, we find that the exogenous variation in oil endowment does not have the same effect on all countries. In most of cases, the event has a negative effect in the long run, but countries with a high level of democracy in the pre-event period are not affected by the peak of oil discoveries. These results support heterogeneity and non-linearities claimed in the more recent theoretical literature.

The present paper follows the method introduced in the seminal Census of Owen Gingerich, and describes three annotated copies of Copernicus’ De Revolutionibus princeps edition. One of them was totally unknown in the literature, being absent from the catalogue of its owner (the Library of the Romanian Academy, Cluj-Napoca Branch). The copies discussed here are rich in annotations, one of them being comparable with the most annotated copies described in the Census. The thesis advanced by Owen Gingerich about the continuity in the reading of Copernicus’ book is again confirmed. Details of the annotations are presented, and their images are for the first time shown in a specialized publication.

Abstract Plasma display panel(PDP) have gained great attention due to their potential application to large‐area display including HDTV. The luminance and luminous efficiency of PDP, however, should be improved to realize this goal. In this study, we examined experimentally the effects of phosphor thickness and discharge gap on the luminance and luminous efficiency of ac PDP. For the rib height of 110 μm, whereas the optimum phosphor thickness was about 30 μm. The optimum thickness of green phosphor was about 50 μm for the rib height of 120∼160 μm.

Leukocyte scintigraphy has previously been used to evaluate gastrointestinal graft-versus-host disease (GVHD). No reports have described their utility in cutaneous GVHD or the ability of leukocyte scintigraphy to evaluate treatment response at any site. This case shows significant radiolabeled leukocyte uptake in a man with extensive cutaneous GVHD, with subsequent near complete resolution after therapy. As such, leukocyte scintigraphy may provide an alternate way to assess the burden of GVHD and response to treatment.

A somatic cell hybrid containing the synovial sarcoma‐associated t(X;18)(p11.2;q11.2) derivative (der(X)) chromosome was used to characterize the translocation breakpoint region on the X chromosome. By using Southern hybridization of DNA from this der(X) hybrid in conjunction with Xp‐region specific radiation reduced cell hybrids and probes, it was found that this breakpoint maps within the ornithine aminotransferase (OAT) L1 cluster. A yeast artificial chromosome (YAC) clone (OAT YAC2) which hybridizes to a human OAT cDNA probe and is known to contain part of the OATL1 cluster was selected and used to confirm these results both by fluorescence in situ hybridization on synovial sarcoma patient material and by hybridization of its end‐clones to the der(X) containing hybrid cells. It was found that indeed the human Xp sequences contained within this YAC are split as a consequence of the (X;18) translocation. Therefore, we conclude that OAT YAC2 spans the synovial sarcoma‐specific translocation breakpoint and, as such, may serve as an ideal starting point from which the gene(s) involved in the development of this soft tissue tumor can be isolated. © 1993 Wiley‐Liss, Inc.

Tyrosine kinase inhibitors, such as imatinib, have dramatically improved the outcomes for patients with selected cancers. For imatinib, western blotting of phospho‐CrkL was an insensitive, indirect, and descriptive method to determine drug efficacy. Greater use of targeted therapies should involve more quantitative evaluation of the target's dose‐inhibition. The Src/Abl kinase inhibitor dasatinib has recently been approved for use in Ph+ leukemias after failure with imatinib. Src family kinases (SFK) also play a critical role in nonhematologic cancers. We have developed a flow cytometric assay to measure SFK autophosphorylation levels in blood mononuclear cells and observed a direct correlation between its inhibition and patient dosage. This method provides a sensitive, quick, and quantitative tool to assess drug efficacy. Pediatr Blood Cancer 2009;53:1132–1135. © 2009 Wiley‐Liss, Inc.

This is the second of a two-volume set covering almost 1500 fish species recorded in and around the Gulf of Mexico containing warm temperate and tropical shelf species. This volume covers Scorpaeniformes, Perciformes, Pleuronectiformes, and Tetraodontiformes, with a short description of the four orders and keys to 83 families followed by family descriptions arranged phylogenetically and keys to 656 species arranged alphabetically. The introduction includes the usual detail on fish morphometrics, identification features, and a biogeographical synopsis of the fishes of the region. Considering its size, the Gulf of Mexico has a rich ichthyofauna containing over 10% of all known species of marine fish, giving it a global importance that demands a comprehensive guide such as this. The introduction also includes new records and emendations to volume 1, which covered Myxiniformes to Gasterosteiformes and was published in 1998. Most species are illustrated with line drawings, a large proportion drawn by the second author. There is a short description of the depth and geographic distribution of each species, although small distribution maps where appropriate would have been helpful. The occasional ecological descriptor is included, where it may help with identification and usually a word or two on diet, maturity, and maximum size. However, the majority of the text is devoted to very detailed morphometric descriptions for each species, allowing little excuse for misidentification. The sources of data for each species are also referenced. Being monotone, this book lacks the colourful attraction of many identification guides, but it is a very workmanlike production, concentrating on the detail necessary for accurate identification to species. I have already found the species descriptions to be useful, assisting in the identification of several warm-water species that have recently turned up on our UK shores. This is always a useful test for an identification guide, and it came through with glowing colours, providing information not available within many of the standard texts. I am impressed with the wealth of information contained within this book and it will undoubtedly prove useful for anyone with an interest in the ichthyofauna of the Gulf of Mexico. However, with the rapid changes we now see in the distribution of fish species, particularly the northward spread of warm-water species, this volume will also prove its usefulness on the shelves of UK readers in coming years.

This article presents two methods of utilizing the spectrum efficiently. One strategy which is called spectrum pooling where the public access is enabled to these bands without giving significant interference to the actual license owners. The other method is Transform Domain Communication System (TDCS) as a candidate technique for CR. In order not to interfere with the occupied spectrum TDCS can shape of the waveform of the transmitted signal dynamically over a spectral region. Performance comparison of TDCS and OFDM based cognitive radio for MIMO system using VBLAST receiver architecture to reconstruct the transmitted data. The results show the most promising interference avoidance technique combined with MIMO V-BLAST architecture to be applied in the CR system.

Introduction While the title to this essay invites only consideration of the police role it is relevant to begin by making the point that prevention (either ofthe occurrence or of its escalation) in this area is no less of general community concern than in some better known aspects of criminal activity. Community representatives, whether elected or not, have a clear responsibility to help defuse situations and equally to avoid 'instant' criticism of police action. This is not to deny the right to criticise particular police action but rather to avoid the generalised allegations of either over-reaction or under-reaction which create a climate in which subsequent police action is then prejudiced. Such a foundation is central to the success of police efforts in avoiding escalation of disorderly situations because this acutely difficult decision-taking must be against a background where the police at least have confidence in their authority to act lawfully in the manner which best suits that particular event. The great success of, for example, the British Police over the years in this area of work has depended to a marked extent on general acceptance of their authority in what has aptly been described as their role of 'order maintenance'I. When that authority is .called in question or undermined it greatly influences police confidence and heightens a crowd's impression of how far it can go. One Writer has put it in these terms:

To characterize the incidence and mortality of the glioblastoma multiforme as it is seen at the primary care level, a retrospective study was done through the Georgia Tumor Registry on 299 patients with histologically confirmed supratentorial glioblastoma multiforme. Specifically, the age incidence distribution, sex ratio, and the postoperative survivals were studied. The Registry also provided the opportunity to define the relative racial frequencies of this neoplasm in a large biracial population. The mean age of the patients at the time of surgery was 58.6 years and the age group having the highest incidence was 60 to 74 years. The overall ratio of affected males to females was 1.04 to 1. The postoperative survival periods were considerably shorter than those reported from large cooperative clinical trials. The overall postoperative survivals at 12 and 24 months were only 22% and 4%, respectively. Advancing age had a strong negative relationship with the length of survival such that the 50% survival for patients less than 30 years of age was 17 months, for those age 30 to 44 years it was 10.2 months, for those age 45 to 59 it was 5.8 months, and for those older than 60 it was only 2.2 months. The study confirmed previous suggestions that the incidence of the neoplasm is considerably higher in whites. There were 2.3 glioblastomas in whites for every one in blacks. No difference was noted in the length of survival between whites and blacks.

For the past ten years, the highest proton energies accelerated with high‐intensity lasers was 58 MeV, observed in 2000 at the LLNL NOVA Petawatt laser, using flat foil targets. Recently, 67.5 MeV protons were observed in experiments at the Los Alamos National Laboratory (LANL) Trident laser, using one‐fifth of the PW laser pulse energy, incident into novel conical targets. We present a focused study of new theoretical understanding of this measured enhancement from collisional Particle‐in‐Cell simulations, which shows that the hot electron temperature, number and maximum energy, responsible for the Target Normal Sheath Acceleration (TNSA) at the cone‐top, are significantly increased when the laser grazes the cone wall. This is mainly due to the extraction of electrons from the cone wall by the laser electric field, and their boost in the forward direction by the v×B term of the Lorentz force. This result is in contrast to previous predictions of optical collection and wall‐guiding of electrons in angled ...

Background Cardiomyocyte contraction requires a constant supply of ATP, which varies depending on work rate. Maintaining ATP supply is particularly important during excitation-contraction coupling, where cytosolic Ca2+ fluxes drive repeated cycles of contraction and relaxation. Ca2+ is one of the key regulators of ATP production, and its uptake into the mitochondrial matrix occurs via the mitochondrial calcium uniporter. Fluorescent indicators are commonly used for detecting cytosolic Ca2+ changes. However, visualizing mitochondrial Ca2+ fluxes using similar methods is more difficult, as the fluorophore must be permeable to both the sarcolemma and the inner mitochondrial membrane. Our aim was therefore to optimize a method using the fluorescent Ca2+ indicator Rhod-2 to visualize beat-to-beat mitochondrial calcium fluxes in rat cardiomyocytes. Methods Healthy, adult male Wistar rat hearts were isolated and enzymatically digested to yield rod-shaped, quiescent ventricular cardiomyocytes. The fluorescent Ca2+ indicator Rhod-2 was reduced to di-hydroRhod-2 and confocal microscopy was used to validate mitochondrial compartmentalization. Cardiomyocytes were subjected to various pharmacological interventions, including caffeine and β-adrenergic stimulation. Upon confirmation of mitochondrial Rhod-2 localization, loaded myocytes were then super-fused with 1.5 mM Ca2+ Tyrodes containing 1 μM isoproterenol and 150 μM spermine. Myocytes were externally stimulated at 0.1, 0.5 and 1 Hz and whole cell recordings of both cytosolic ([Ca2+]cyto) and mitochondrial calcium ([Ca2+]mito) transients were made. Results Myocytes loaded with di-hydroRhod-2 revealed a distinct mitochondrial pattern when visualized by confocal microscopy. Application of 20 mM caffeine revealed no change in fluorescence, confirming no sarcoplasmic reticulum compartmentalization. Myocytes loaded with di-hydroRhod-2 also showed a large increase in fluorescence within the mitochondria in response to β-adrenergic stimulation (P < 0.05). Beat-to-beat mitochondrial Ca2+ transients were smaller in amplitude and had a slower time to peak and maximum rate of rise relative to cytosolic calcium transients at all stimulation frequencies (P < 0.001). Conclusion Myocytes loaded with di-hydroRhod-2 revealed mitochondrial specific compartmentalization. Mitochondrial Ca2+ transients recorded from di-hydroRhod-2 loaded myocytes were distinct in comparison to the large and rapid Rhod-2 cytosolic transients, indicating different kinetics between [Ca2+]cyto and [Ca2+]mito transients. Overall, our results showed that di-hydroRhod-2 loading is a quick and suitable method for measuring beat-to-beat [Ca2+]mito transients in intact myocytes.

We have developed a selective and sensitive colorimetric method for determination of Fe3+ ion by using p-amino salicylic acid dithiocarbamate functionalized gold nanoparticles (DTC-PAS-Au NPs) as colorimetric probes. The DTC-PAS-Au NPs were characterized by FT-IR, 1H NMR, UV-visible spectrometry, transmission electron microscopy (TEM), dynamic light scattering (DLS) and atomic force microscopic (AFM) techniques, respectively. The DTC-PAS-Au NPs are aggregated rapidly by addition of Fe3+ ions, yielding a color change from red to blue. The characteristic surface plasmon resonance (SPR) peak (520 nm) of DTC-PAS-Au NPs was shifted to longer wavelength, 700 nm, which confirms the ligand-to-metal charge transfer between DTC-PAS-Au NPs and Fe3+ ions. Under the optimal conditions, a good linear relationship (correlation coefficient R2 = 0.993) was obtained between the ratio of the extinction at 700 nm to that at 520 nm and the concentration of Fe3+ over the range of 40–80 μM, with a detection limit of 14.82 nM. The DTC-PAS-Au NPs acted as colorimetric sensors for the selective detection of Fe3+ ions in real samples (blood and urine samples).

By using parallel culture techniques, the recovery rates of a wide spectrum of organisms encountered in hypertonic clinical blood cultures was determined from four different blood culture bottles. Each bottle was identical except for the amount of sodium polyanethol sulfonate (SPS) present. Flasks A, B, C, and D contained SPS in final concentrations of 0.025, 0.05, 0.075, and 0%, respectively. Of 144 patients found to have clinically relevant organisms in their blood cultures, 127 had positive A flasks, 144 had positive B flasks, 140 had positive C flasks, and 110 had positive D flasks. There was no significant difference in the time required to obtain organism recovery from the A, B, or C flasks; however, the time required to obtain organism recovery from the D flask was considerably longer, ranging up to 5 days in many cases. Of the various organisms recovered, 3 of 7 strains of anaerobic streptococci and 1 of 28 strains of Streptococcus pneumoniae appeared to be inhibited by SPS when the concentration was 0.075%. In no case was an organism recovered from either the A or D flask but not from the B flask, indicating that a concentration of 0.05% SPS in hypertonic media does not inhibit the growth of a wide spectrum of organisms in clinical blood cultures.

Abstract The use of electronic cigarettes has increased markedly in recent years, however, as the popularity of e-cigarettes has increased, so has the controversy associated with their use. In this paper we report the views of a small sample of e-cigarette users focussing on the circumstances in which individuals began vaping, their reasons for continuing vaping, their perceptions of the relative harm of vaping compared to smoking, and their views as to whether their use of e-cigarettes had increased their likelihood of smoking. In total we interviewed 50 vapers aged between 16 and 26. Typically, vapers explained their continued use of e-cigarettes in terms of the reduced harm compared to smoking, the lack of an offensive smell, the appeal of different flavours, the greater range of settings in which e-cigarettes could be used, and the reduced stigma associated with their use. The sample of interviewees were evenly split with regard to the perceived justification (or not) for banning vaping in public. Finally, we make the case that it is important to base policy and regulation of e-cigarettes on both robust epidemiological data on the impact of these devices as well as more qualitative, ethnographic, information from users themselves.

During the casting process, the crust of the steel wire is permanently subjected to thermo mechanical stresses (temperature variations, pulling, bending and straightening forces, ferrostatic pressure), which, when exceeding the deformation capacity of the crust, can lead to cracks.Therefore, it is necessary to know what kind of stresses act on the crust and how the steel behaves at high temperatures at certain process parameters (extraction speed, cooling intensity, etc.).

In this paper, we explore the possibility of sparse regression, a new direction in unmixing, for vegetation and urban area classification. SUnSAL (Sparse unmixing via variable splitting and augmented Lagrangian) in both unconstrained and constrained forms (with the abundance non-negativity and abundance sum-to-one constraints) were used with a set of global endmembers (substrate, vegetation and dark objects) to unmix a set of computer simulated noise-free and noisy data (with Gaussian noise of different signal-to-noise ratio) in order to judge the robustness of the algorithm. The error in the fractional estimate was examined for varying noise power (variance): 2, 4, 8, 16, 32, 64, 128 and 256. In the second set of experiments, a spectrally diverse collection of 11 scenes of Level 1 terrain corrected, cloud free Landsat-5 TM data representing an agricultural setup in Fresno, California, USA were used. The corresponding ground data for validation were collected on the same days of satellite overpass. Finally in the third set of experiments, a clear sky Landsat-5 TM data for an area near the Golden Gate Bridge, San Francisco (an urbanized landscape), California, USA were used to assess the algorithm. The fractional estimates of the 30 m Landsat-5 TM data were compared with the fractional estimates of a high-resolution World View-2 data (2 m spatial resolution) obtained using a fully constrained least squares algorithm. The results were evaluated using descriptive statistics, correlation coefficient, RMSE, probability of success and bivariate distribution function, which showed that constrained model was better than unconstrained form.

Gaucher disease (GD) is an autosomal recessive lysosomal storage disorder caused by mutations in the GBA1 gene, which produces the glucocerebrosidase (GCase) protein. There are more than 500 mutations reported in GBA1, among which L444P (p.Leu444Pro) and F213I (p.Phe213Ile) are the most common in the Chinese population, while the function of F213I mutation remains elusive. This study aims to establish the GD mouse model of partially humanized Gba1 gene with F213I mutation. In vitro GCase activity assays showed that the product of partially humanized Gba1 gene, in which the mouse exons 5-7 were replace by the corresponding human exons, displayed similar activity with the wild-type mouse Gba1, while the F213I mutation in the humanized Gba1 led to significant decrease in enzyme activity. ES cell targeting was used to establish the mice expressing the partially humanized Gba1-F213I. Gba1 F213I/+ mice did not show obviously abnormal phenotypes, but homozygous Gba1 F213I/F213I mice died within 24 h after birth, whose epidermal stratum corneum were abnormal from the wild-type. The GCase activity in Gba1 F213I/F213I mice greatly decreased. In conclusion, our results showed that the partially humanized GD mouse model with the F213I mutation was developed and homozygous F213I mutation is lethal for newborn mice.

Miscibility, crystallization, and mechanical properties of blends of thermosetting polyimide PMR-15 and phenolphthalein poly(ether ketone) (PEK-C) were examined. With the exception of the 90/10 blend, which has two glass transition peaks, all the blends with PMR-15 less than 90 wt % are miscible in the amorphous state according to DMA results. Addition of PEK-C hindered significantly the crystallization of PMR-15, indicating that there must exist some kind of interaction between molecular chains of PMR-15 and those of PEK-C. The semi-IPN system of PMR-15/PEK-C blends exhibits good toughness. Two distinct microphases, interweaving at the phase boundaries, were found in the PMR-15/PEK-C 60/40 blend. The toughness effect of the blends is discussed in terms of the interface adhesion between the two distinct phases and the domain sizes of the phases. The relation between miscibility and toughness of the blends was investigated. (C) 1996 John Wiley & Sons, Inc.

Despite the fact that labels such as “smart industry” and “industry 4.0” (terms used to denote the fourth industrial revolution) have become popular topics within academia and in practice, their meaning remains an issue of concern. It’s a concern that has drawn the attention of various authors. It is a struggle we engaged in as well – specifically regarding the Dutch “smart industry” label – to aid our aim of assessing whether our call to combine forces can be extended beyond industry 4.0 and industrie 4.0. We provide here initial indications of whether there is more unity in meaning and, thus, reasons to take steps toward combining labels. By means of 20 interviews with Dutch smart industry experts, a representation of smart industry was obtained as understood in the Netherlands. Based on this representation, we examined the extent of overlap between the Dutch “smart industry” label and the general term “fourth industrial revolution” as well as the “industry 4.0” label as defined by various scholars. Our findings showed that smart industry in the Netherlands does not match the denotation of an industrial revolution. Several signals were, however, detected indicating that the content observed under the Dutch smart industry label overlaps with what is being presented under the label industry 4.0. These results reveal that there is indeed more unity in meaning between the various labels that exist and, as such, strengthens our call to combine forces.

Based on the paradigm changes for health, health services and underlying technologies as well as the need for at best comprehensive and increasingly automated interoperability, the paper addresses the challenge of knowledge representation and management for medical decision support. After introducing related definitions, a system-theoretical, architecture-centric approach to decision support systems (DSSs) and appropriate ways for representing them using systems of ontologies is given. Finally, existing and emerging knowledge representation and management standards are presented. The paper focuses on the knowledge representation and management part of DSSs, excluding the reasoning part from consideration.

<p>Wave-following buoys are used to provide measurements of free surface elevation across the oceans. The measurements they produce are widely used to derive wave-averaged parameters such as significant wave height and peak period, alongside wave-by-wave statistics such as crest height distributions. Particularly concerning the measurement of extreme wave crests, these measurements are often perceived to be less accurate. We directly assess this through a side-by-side laboratory comparison of measurements made using Eulerian wave gauges and model wave-following buoys for directionally spread waves representative of extreme conditions on deep water. Our experimental measurements are compared to exact (Herbers and Janssen 2016, J. Phys. Oceanogr, 46, 1009-1021) and new approximate expression for Lagrangian second-order theory derived herein. We derive simple closed-form expressions for the second-order contribution to crest height representative of extreme ocean waves. Our experiments confirm that the motion a wave-following buoy should not significantly affect the measurements of wave crests or spectral parameters, and that discrepancies observed for in-situ buoy data are most likely a result of filtering. This filtering occurs when accelerations that are measured by the sensors within a buoy are converted to displacements. We present an approximate means of correcting the resulting measured crest height distributions, which is shown to be effective using our experimental data.</p>

Este trabalho discute as questoes que permeiam a constituicao dos monumentos funebres, entendidos como uma manifestacao cultural formada e legitimada constantemente por intermedio do trauma e do tabu sobre a morte, e que, por conseguinte, possuem em sua essencia o que entendemos como evidencia de angustia. O procedimento metodologico aplicado e o estudo de caso, pois sera analisado o monumento escultorico de uma carpideira segundo a logica em que um sujeito ou objeto nos permite uma reflexao do corpo social avaliado. O trabalho desenvolve-se da seguinte maneira: primeiramente, discorreremos sobre o conceito de monumento, sua formacao fisica e como esta permite o dialogo entre a memoria e a morte. Na sequencia, refletiremos sobre os conceitos de trauma, tabu e angustia, vistos como uma triade que molda a subjetividade inerente a existencia dos monumentos escultoricos. Por fim, analisaremos um monumento escultorico localizado no Cemiterio de Sao Joao Batista em Botafogo, Rio de Janeiro. A reflexao conceitual, em consonância com a metodologia do estudo de caso, demonstra o quanto os monumentos escultoricos, desde a sua edificacao ate a sua constante manutencao pela sociedade, refletem a mentalidade sobre a morte por intermedio de um entrelacamento entre a cultura, a arte, a memoria, ou seja, de aspectos que nos moldam, o que nos faz pensar nos monumentos como “espelhos da sociedade”.

WHEN A SPEAKER is invited to address a medical society, it may safely be assumed that its members (or at least the less jaundiced among them) anticipate enlightenment or entertainment or, mirabile dictu, both. How often these expectations are rewarded is quite another matter, upon which each of us will hold his own opinion. But it would seem to require some word of justification when a speaker arrives, as I do this evening, not to offer help but to seek it.
This is all the more unusual in view of the frequency with which psychiatrists are asked to advise pediatricians, and the relative rarity of the converse. A curious state of affairs, indeed, unless one were to assume that the psychiatrist knows all that the pediatrician does, plus something more—or that what the pediatrician knows is of no consequence for the psychiatrist. No one would seriously maintain the former statement, and the latter is no less patently absurd.
How this relationship between the two specialties has come to be is an interesting historical question, but not our present concern. However, its existence is to the detriment of both the psychiatrist and the pediatrician. It is with the hope that you will enter the lists in the struggle for the advancement of psychiatric knowledge that I propose to review what is known of preventive psychiatry. You will discern that a substantial part of it is pediatrics, has been contributed by pediatricians along with other specialists, and very much concerns pediatric practice.

This paper investigates mobile relaying in wireless powered communication networks (WPCN), where an unmanned aerial vehicle (UAV) is employed to help information delivery from multiple sources to destination with communication channels severely blocked. The sources are low-power without energy supply. To support information transmission, the UAV acts as a hybrid access point (AP) to provide wireless power transfer (WPT) and information reception for sources. We set the issue of system throughput maximization as the optimization problem. On the one hand, the system is subject to the information causality constraint due to the dependent processes of information reception and transmission for the UAV. On the other hand, the sources are constrained by a so-called neutrality constraints due to the dependent processes of energy harvesting and energy consumption. In addition, we take account of the access delay issue of all ground nodes. Specifically, two paradigms of delay-tolerant case and delay-sensitive case are presented. However, the formulated problem including optimizations for time slot scheduling, power allocation and UAV trajectory is non-convex and thus is difficult to obtain its optimal solution. To tackle this problem, we apply the successive convex approximation (SCA) technique and propose an iterative algorithm by which a suboptimal solution can be achieved. Simulation results validate our proposed design, and show that the obtained suboptimal solution is high-quality, as compared to benchmark scheme.

The mobility of zinc in coastal landfill sites reclaimed by municipal solid waste incinerator ash (MSWIA) was modeled and investigated by conducting a large column test. Temporal and spatial variations in the pH, redox potential (Eh), total organic carbon, and microbial activity were measured in pore water to observe their influences on the mobility of heavy metals throughout the test. After 502 days, permeation was terminated. Then to determine the content and forms of Zn along the column, MSWIA and marine clay samples were analyzed by the community bureau of reference modified sequential extraction procedure. Zn was partitioned into four defined chemical fractions: exchangeable, reducible, oxidizable, and residual. The results showed that attenuation processes occurred within the ash layer, Zn mobility was minor, and coastal landfill conditions promoted the immobilization of heavy metals. Both pH and Eh were the main factors for controlling the solubility of Zn. Moreover, under reduced-alkaline conditions, the reducible fraction was affected, but the oxidizable fraction was slightly favored. The formation of zinc sulphides might be another attenuation mechanism for Zn.

Simulating mixed-signal circuit designs needs to bridge between the analog and digital circuit domains. Preserving the behavior and structure of the analog and digital parts of the circuit is possible with Hardware Description Languages (HDLs), such as Verilog-AMS. However, the analog and digital parts of the design are typically developed in simulation environments tailored to either the analog or digital design flow requirements. For digital circuit development, Verilog is a popular choice of HDL. Including the analog part of the mixed-signal circuit in the Verilog description without the AMS extension requires a modeling strategy that can preserve fundamental analog behavior. In this contribution we describe a method of modeling analog sub-circuits in Verilog. The higher-level analog circuit is modeled by netlisting the connectivity of sub-circuits based on a schematic. This method of modeling and hierarchical netlisting is scalable and demonstrated for the example of an Analog-to-Digital Converter (ADC). We can simulate the digital design interacting with the analog circuit on any standard Verilog simulator, thus, (proprietary) language extensions are not required.

ABSTRACT Social service organizations are commonly asked to account for services, and increasingly, to measure the outcomes of the work with vulnerable populations. Since the advent of the personal computer, software and hardware to assist professionals in collecting both process and outcomes data have improved exponentially. Yet, in many cases, organizations implement computerized management information systems which are underutilized or poorly utilized. The reasons that social service organizations do not use MISs are not well understood. Using a case example of the development of a computerized management information system, this paper suggests that understanding MIS utilization involves examining specific aspects of leadership, technical capacity and systems readiness in the real-world settings of social service organizations.

Quaternary ammonium salt cationic surfactants are inevitably involved in many industrial applications because of their distinguishingly chemical performances, but the effect of anions on different performances of quaternary ammonium salt cationic surfactants is also scarcely discussed. In this study, four carboxylic quaternary ammonium surfactants, cetyl-trimethyl ammonium acetate (CTAAC), cetyl-trimethyl ammonium butyrate (CTABU), cetyl-trimethyl ammonium hexanoate (CTAHE) and cetyl-trimethyl ammonium caprylate (CTACA) were prepared to study the effect of carboxylate groups on the performances of four surfactants. Surface properties including critical micelle concentration (CMC), the surface tension at the CMC (γCMC), maximum surface excess (гmax), minimum surface area (Amin) were investigated. The results showed that the surface activity of CTAAC was the highest compared with other members in the prepared surfactants. Foamability and foam stability of four surfactants were evaluated with the standard RossMiles method. The results indicated that foamability and foam stability followed the order of CTAAC > CTABU > CTAHE > CTACA under the same condition. In addition, the emulsion stability measurements of surfactants showed their low emulsifying tendency towards crude oil at 60°C.

In this work, an attempt has been made to perform asymmetry analysis in breast thermograms using non-linear total variation diffusion filter and reaction diffusion based level set method. Breast images used in this study are obtained from online database of the project PROENG. Initially the images are subjected to total variation (TV) diffusion filter to generate the edge map. Reaction diffusion based level set method is employed to segment the breast tissues using TV edge map as stopping boundary function. Asymmetry analysis is performed on the segmented breast tissues using wavelet based structural texture features. The results show that nonlinear total variation based reaction diffusion level set method could efficiently segment the breast tissues. This method yields high correlation between the segmented output and the ground truth than the conventional level set. Structural texture features extracted from the wavelet coefficients are found to be significant in demarcating normal and abnormal tissues. Hence, it appears that the asymmetry analysis on segmented breast tissues extracted using total variation edge map can be used efficiently to identify the pathological conditions of breast thermograms.

ABSTRACT This paper reports on how teachers, from different cities in Brazil, used groups on Facebook and how communication between teachers and students was affected by using such groups. This study is framed under the Cultural Historical Activity Theory (CHAT) perspective, and is conceived from a methodological background that invites participants to collaborate during the research. We examined posts from the groups on Facebook from February 2013 to June 2014 by a qualitative approach, together with coding the open-ended qualitative data and comparing their distribution, and analyzed responses to a questionnaire for teachers by the end of the research. Our findings suggest the teachers used the groups for different purposes, which led to an improvement in communication between teachers and students—online and in-classroom—and in students’ engagement in the classrooms.

A selected review of the literature on caring in nursing is presented. The review relies on the work of the major theorists in this area. The major conceptualizations of caring are compared and contrasted, along with some of the research approaches which have been applied to investigate the phenomenon of caring in nursing. The outcome of quantitative and qualitative research on caring is described and the justification for an extension of the quantitative work, through the development of an appropriate inventory and the application of multivariate statistical analysis, is discussed.

Ultrasonic tandem inspection techniques are widely used to detect midwall defects. Conventionally, a pair of probes scans the specimen, one transducer at transmission, one at reception. An alternative application relies on the selection of different elements over an array, some at transmission, others at reception. Simulation tools for tandem inspection have been integrated into the Civa software developed at CEA, with support from EWI. This paper presents some simulation examples for contact monolithic and phased arrays probes.

Simulating complex biological models consisting of multiple ordinary differential equations can aid in the prediction of the pharmacological/biological responses; however, they are often hampered by the availability of reliable kinetic parameters. In the present study, we aimed to discover the properties of behaviors without determining an optimal combination of kinetic parameter values (parameter set). The key idea was to collect as many parameter sets as possible. Given that many systems are biologically stable and resilient (BSR), we focused on the dynamics around the steady state and formulated objective functions for BSR by partial linear approximation of the focused region. Using the objective functions and modified global cluster Newton method, we developed an algorithm for a thorough exploration of the allowable parameter space for biological systems (TEAPS). We first applied TEAPS to the NF-κB signaling model. This system shows a damped oscillation after stimulation and seems to fit the BSR constraint. By applying TEAPS, we found several directions in parameter space which stringently determines the BSR property. In such directions, the experimentally fitted parameter values were included in the range of the obtained parameter sets. The arachidonic acid metabolic pathway model was used as a model related to pharmacological responses. The pharmacological effects of nonsteroidal anti-inflammatory drugs were simulated using the parameter sets obtained by TEAPS. The structural properties of the system were partly extracted by analyzing the distribution of the obtained parameter sets. In addition, the simulations showed inter-drug differences in prostacyclin to thromboxane A2 ratio such that aspirin treatment tends to increase the ratio, while rofecoxib treatment tends to decrease it. These trends are comparable to the clinical observations. These results on real biological models suggest that the parameter sets satisfying the BSR condition can help in finding biologically plausible parameter sets and understanding the properties of biological systems.

Aim Downhill varices are not so safe as thought and can lead to life-threating or mortal bleeding complication, even if rare. In order to draw attention to this topic, we analysed 129 patients. Materials and Methods We evaluated the electronic endoscopy data records of all patients undergoing upper gastrointestinal endoscopy over a nine-year period from January 2004 till December 2012, within a retrospective approach. The primary endpoints, incidence, causes, kind of resulting upper gastrointestinal bleeding, and the severity of the bleeding were evaluated. Secondary endpoints were the evaluation of the size of downhill varices and a comparison of the risk of bleeding between downhill varices and uphill varices. Results Downhill varices were identified, described, and/or documented in 129 patients of 25,680 upper gastrointestinal endoscopies. 26 patients had central venous catheter or port implantation, 22 patients had a history of an implantation of a cardiac pacemaker, 7 patients had severe pulmonary artery embolism, and 4 patients had severe chronic obstructive pulmonary disease. Two patients had mediastinal tumors, and one patient had a large retrosternal goiter as a possible cause of the vena cava syndrome. Altogether, 62 patients were related to a vena cava superior syndrome; 67 were not. Conclusions Downhill varices can be seen with an incidence of 0.5%. Therapeutic means are the banding therapy as a safe and effective option. Severe bleedings associated with downhill varices can be mortal. Severe forms of downhill varices should be examined in relation to the origin in order to start a specific therapy.

Las politicas 1:1 nacionales se concretaron en Espana con el programa «Escuela 2.0» pero, en el caso de la Comunidad de Madrid, la concrecion de esta politica se denomina «Institutos de Innovacion Tecnologica». A diferencia del programa Escuela 2.0, se caracteriza por el tipo de dotacion y cursos a los que se dirigia. En este caso, en vez de ordenadores portatiles, se opto por terminales fijos anclados al suelo que dependen de varios servidores por aula y, en vez de llevarse a cabo en 5o y 6o de primaria, se comenzo a implantar en 1o y 2o de la ESO. Una politica TIC que quiere producir cambios en los centros de educacion secundaria obligatoria que participan en el proyecto para aumentar el exito educativo del alumnado, entendido como mejora de los resultados academicos. En este trabajo se presentan las opiniones y expectativas del profesorado de educacion secundaria de la Comunidad de Madrid respecto al impacto que tendra esta politica en sus practicas docentes, en la forma de agrupar al alumnado, en el uso de materiales didacticos digitales y en las habilidades digitales del alumnado.AbstractNationals Spain policies 1:1 were specified in most of Spain's territories through the «School 2.0» program, but in the case of the Community of Madrid, the national policy was defined through the «Technological Innovation Schools» program. This latter program aimed to introduce changes on the use of ICT in the Secondary Schools which joined the project, in order to increase the educational success of students, understood as improving academic outcomes. Both programs differ in the kind of technological equipment provided to the centers and in the grades targeted. Unlike the "School 2.0" program, which provided laptops to the schools, in Madrid fixed terminals fastened to the floor were chosen, which depended on multiple servers per classroom. On the other hand, rather than focus in 5th and 6th grade, it was implemented in 1st and 2nd grade of Secondary Education. In this study, the Secondary Education teachers' opinions and expectations about the impact of this policy in their teaching practices (students grouping, use of digital learning materials and students' digital competences) are described.

For an intelligent unmanned airship equipped with multiple propellers, a reconfiguration scheme is proposed based on the pseudo-inverse method to deal with actuators faults. First, we introduce the structural layout of the considered intelligent unmanned airship, and establish its mathematical model. A LQR optimal controller is designed for the fundamental flight control system. Then, a general model of the actuator-input encountered with faults has been considered. In order to maintain the stability of the airship's attitude, the pseudo-inverse method is employed to reconfigure the control mixer. The control coinmands are thus reassigned to the effective actuators. Finally, the simulation results illustrate the effective and simple structure of our Fault-tolerant reconfiguration control method.

Purpose: To evaluate a first pass analysis (FPA) technique for CT perfusion measurement in a swine animal and its validation using fractional flow reserve (FFR) as a reference standard. Methods: Swine were placed under anesthesia and relevant physiologic parameters were continuously recorded. Intra-coronary adenosine was administered to induce maximum hyperemia. A pressure wire was advanced distal to the first diagonal branch of the left anterior descending (LAD) artery for FFR measurements and a balloon dilation catheter was inserted over the pressure wire into the proximal LAD to create varying levels of stenosis. Images were acquired with a 320-row wide volume CT scanner. Three main coronary perfusion beds were delineated in the myocardium using arteries extracted from CT angiography images using a minimum energy hypothesis. The integrated density in the perfusion bed was used to calculate perfusion using the FPA technique. The perfusion in the LAD bed over a range of stenosis severity was measured. The measured fractional perfusion was compared to FFR and linear regression was performed. Results: The measured fractional perfusion using the FPA technique (P_FPA) and FFR were related as P_FPA = 1.06FFR – 0.06 (r2 = 0.86). The perfusion measurements were calculated with only three to five total CT volume scans, which drastically reduces the radiation dose as compared with the existing techniques requiring 15–20 volume scans. Conclusion: The measured perfusion using the first pass analysis technique showed good correlation with FFR measurements as a reference standard. The technique for perfusion measurement can potentially make a substantial reduction in radiation dose as compared with the existing techniques.

Nowadays Aiton is a small village located in the center part of the Cluj County, between Turda and Cluj-Napoca. At Aiton, during the Roman times, an important rural settlement was established, in close relation with the main road of Roman Dacia. Archaeological investigations in the area of this village were carried out mostly in the last century, but most are accidental discoveries. During the Roman period, Aiton was probably an important rural settlement within the territory of Potaissa, and we suppose that a taberna was set up here. Why? First, because of the distance from Potaissa: 10 Roman miles. Second, because of the discoveries within the territory of the village. My purpose is to analyze, interpret and map all data available. Based on what we know so far, I was able to distinguish two areas with Roman discoveries. One is located in the northern part of the village, close to the Roman road. I reached the conclusion that in this part of the village we should locate the former taberna. The other area in located in the eastern part of the village. I concluded that we should locate the rural settlement here. All in all, these data allowed me to conclude that Aiton represented, during Roman times, an important settlement between Potaissa and Napoca.

murders of landowners for which the Cabinet believed the Catholic clergy was partly responsible. And in Britain, the rapidly increasing Catholic population and the Oxford Movement made the issue of Episcopal hierarchy more pressing. Things were also blurred by the policy carried out by Pius IX himself: although posterity remembers him as a reactionary who declared the doctrine of papal infallibility as well as the immaculate conception of the Virgin Mary and who opposed Italian unification, for a brief but agitated period of time he granted political amnesty and undertook some constitutional reforms to modernize the political regime of the Papal States and was supported by the liberals. The radicalization of Italian politics transformed him into an arch-conservative eager to preserve (and then get back) his temporal power with the help of the Catholic foreign powers. Matsumoto-Best’s wording at times is open to question. For example, she writes that Naples was ‘convulsed’ by the revolutions of 1820-1 (11), that the pope’s reforms created ‘dangerous expectations’ (70), that John O’Connell had become the leader of the Irish repeal movement (99) (whereas the son of the Liberator competed with Young Ireland for the leadership), and that ‘Catholic subjects in Britain agreed with the pope’ (p. 130), which remains to be proven. She also incorrectly states that the liberal Westminster Review was a ‘conservative’ journal (75), that elected president Louis Napoleon was ‘appointed’ (117) and that MP John Roebuck’s first name was James (126). But on the whole this study is a very rigorous and highly informative one. The impact of the revolutions taking place in Austria or France need further discussion, but this is not the purpose of this book, which is pretty thorough in its treatment of the topic – that of the attempted and aborted relation between Pius IX and Palmerstonian politics.

As an effective technique for combating multipath fading and for high-bit-rate transmission over wireless channels, orthogonal frequency-division multiplexing (OFDM) is extensively used in modern terrestrial digital television broadcasting systems to support high performance bandwidth-efficient multimedia services. Cutoff rate and outage probability are two important criteria to evaluate the performance of a practical communication system in radio engineering. In this paper, the cutoff rate and outage probability performance are compared between two important terrestrial digital television broadcasting systems, the cyclic prefix OFDM based DVB-T system and the time domain synchronous OFDM based DMB-T system, under different mobile multipath channel conditions. The DVB-T system and the DMB-T system are summarily introduced. The cutoff rate and outage probability expressions are developed, and simulation results are given for both the DVB-T system and the DMB-T system.

In traditional e-learning, teachers design sets of Learning Objects (LOs) and organize their sequencing; the material implementing the LOs could be either built anew or adopted from elsewhere (e.g. from standard-compliant repositories) and reused. This task is applicable also when the teacher works in a system for personalized e-learning. In this case, the burden actually increases: for instance, the LOs may need adaptation to the system, through additional metadata. This paper presents a module that gives some support to the operations of retrieving, analyzing, and importing LOs from a set of standard Learning Objects Repositories, acting as a recommending system. In particular, it is designed to support the teacher in the phases of (i) retrieval of LOs, through a keyword-based search mechanism applied to the selected repositories; (ii) analysis of the returned LOs, whose information is enriched by a concept of relevance metric, based on both the results of the searching operation and the data related to the previous use of the LOs in the courses managed by the Learning Management System; and (iii) LO importation into the course under construction.

The convex surface of the infrared dome is exposed to the harsh environment of the outside world, and therefore requires a coating which not only increases transmission but is able to withstand rain erosion so as to enhance system performance. This paper deals with the techniques that were developed to deposit a uniform thick SiO2 coating for sapphire dome by radio frequency magnetron sputtering. Results show that average transmission increment in wavelength range from 3 to 5um for the sapphire dome coated on convex surface was more than 4.0%. The transmission non-uniformity over the convex surface of the coated sapphire dome was less than 1.7%.

Kawasaki has developed a methodology for estimating car body low mode bending and torsion mode natural frequency. These natural frequencies have a significant influence on ride quality. Although it has been believed that the natural frequencies become lower when passengers are present, Kawasaki established that the natural frequency does not change with the number of standing and sitting passengers, and the vibration acceleration amplitude becomes smaller when passengers are present. This has been shown by implementing numerical analyses and experiments using a mock up car. The increased knowledge will enable designing for better ride quality in the future through optimization of more accurate models.Copyright © 2002 by ASME

The paper examines the relationship between financial inclusion and macroeconomic performance in Nigeria from 1981 to 2014. The data for the study were sourced from Central Bank of Nigeria statistical bulletins. The study employs the Ordinary Least Square and Granger Causality tests as estimation techniques. From the result, using the coefficient, Gross Domestic Product (GDP) is positive at constant of 2573.946. This means that when all variables are held constant, there will be a positive variation up to 2573.946 units in GDP. This implies that there is a significant and positive effect of financial inclusion on macroeconomic performance in Nigeria. It is concluded that Credit to the Private Sector as a ratio of GDP (CPS/GDP), Money Supply as a ratio of GDP (MS/GDP), and Numbers of Bank Branches (NBB) have a unidirectional relationship to GDP – while Currency Out Banks (COB), Interest Rate (INT) and Total Saving (TSA)are independent of GDP. The study therefore recommends that the government and the Central Bank of Nigeria should improve on the facilitation of credit to the private sector, and money supply should be properly managed. The Central Bank of Nigeria should encourage the provisions of more bank branches to rural and urban areas in order to promote easy access to financial services.

In Deep Reinforcement Learning (DRL) for robotics application, it is important to find energy-efficient motions. For this purpose, a standard method is to set an action penalty in the reward to find the optimal motion considering the energy expenditure. This method is widely used for the simplicity of implementation. However, since the reward is a linear sum, if the penalty is too large, the system will fall into local minima and no moving solution can be obtained. In contrast, if the penalty is too small, the effect may not be sufficient. Therefore, it is necessary to adjust the amount of the penalty so that the agent always moves dynamically, and the energy-saving effect is sufficient. Nevertheless, since adjusting the hyperparameters is computationally expensive, we need a learning method that is robust to the penalty setting problem. We investigated on the Spiking Neural Network (SNN), which has been attracting attention for its computational efficiency and neuromorphic architecture. We conducted gait experiments using a hexapod agent while varying the energy penalty settings in the simulation environment. By applying SNN to the conventional state-of-the-art DRL algorithms, we examined whether the agent could explore for an optimal gait with a larger penalty variation and obtain an energy-efficient gait verified with Cost of Transport (CoT), a metric of energy efficiency for gait. Soft Actor-Critic (SAC)+SNN resulted in a CoT of 1.64, Twin Delayed Deep Deterministic policy gradient (TD3)+SNN resulted in a CoT of 2.21, and Deep Deterministic policy gradient (DDPG)+SNN resulted in a CoT of 2.08 (1.91 for normal SAC, 2.38 for TD3, and 2.40 for DDPG). DRL combined with SNN succeeded in learning more energy efficient gait with lower CoT.

This paper presents a new upper bound on the end-to- end signal-to-noise ratio (SNR) of channel-assisted amplify-and-forward (AF) multi-hop relay networks. The harmonic mean of the minimum of the first P >= 0 hop SNRs and the minimum of the remaining hop SNRs forms the new bound. Closed-form expressions are derived for the cumulative distribution function and the moment generating function of this SNR upper bound for independent and non-identically distributed Rayleigh, and independent and identically distributed Nakagami-m fading, where m is an integer. The outage probability and the average symbol error rate bounds are also derived. Our proposed bounds are compared against the existing bounds.

A fast multichannel Stokes/Mueller polarimeter with no mechanically moving parts has been designed to have close to optimal performance from 430-2000 nm by applying a genetic algorithm. Stokes (Mueller) polarimeters are characterized by their ability to analyze the full Stokes (Mueller) vector (matrix) of the incident light (sample). This ability is characterized by the condition number, κ, which directly influences the measurement noise in polarimetric measurements. Due to the spectral dependence of the retardance in birefringent materials, it is not trivial to design a polarimeter using dispersive components. We present here both a method to do this optimization using a genetic algorithm, as well as simulation results. Our results include fast, broad-band polarimeter designs for spectrographic use, based on 2 and 3 Ferroelectric Liquid Crystals, whose material properties are taken from measured values. The results promise to reduce the measurement noise significantly over previous designs, up to a factor of 4.5 for a Mueller polarimeter, in addition to extending the spectral range.

The present investigation was carried out during Kharif seasons of year 2013-14 and 2014-15 at the Instructional Dairy Farm of G.B. Pant University of Agriculture and Technology, Pantnagar. The experimental material was developed by mating five male sterile lines as tester parents of sorghum with eight lines in line x tester mating design. The field experiment with 55 treatments including 40 F1s, 5 CMS lines as testers, 8 pollinator lines as lines and two standard checks was planted in randomized block design with three replications during both years in kharif seasons. Among pollinators, 11A2 and M35-1 performed best with all testers. For green fodder yield, most of the crosses exhibited singnificant and positive values for batter parent and mid parent heterosis while singnificant and positive standard parent heterosis was recorded only for one cross i.e. 11A2 x UPC2 (16.34). Among all crosses, 11A2 x UPC2 performed best for most of the characters and can be recommended as potential parental combination for further testing for varietal improvement of sorghum.

This article connects recent research on failed states with Nuruddin Farah’s novel Knots to argue that literature can model alternative forms of state organization as well as point to the limitations of the conceptual term “failed state.” Farah’s novel draws attention to the problematically gendered nature of failed state theories and mobilizes storytelling as a medium to present imaginative alternatives to the traditional nation-state model that the United Nations has tried to install in Somalia. Both the recovery of Cambara’s family home and the play performed within its walls are made possible by the Women’s Network for Peace, a grassroots collective of women whose members are based primarily in Mogadiscio but also extend transnationally. I offer a reading of Knots that not only concurs with critiques of the “failed state” concept but also suggests the Women’s Network as an alternative model for governance in the absence of centralized government. Knots revises the narrative of failure by portraying a metric of “success” within the much-maligned Somalia that prevailing considerations of state failure dismiss.

Identification of suitable instruments is a critical step for the implementation of instrumental variable (IV) estimation. A challenge is that, as the level of correlation between the instruments and the endogenous variable increases, so also do the chances that the instruments themselves will be correlated with the error terms. Contrariwise, when the correlation with the endogenous variable is low, the instruments may be weak and perform poorly. The objective of this paper is to explore the use of synthetic variables in IV estimation when the analysis is of spatial data series. The point of departure is the use of eigenvector analysis of the usual spatial weights matrix used in spatial statistics. Eigenvectors obtained from a transformed weights matrix are known to represent latent map patterns. Our proposal is to use these patterns to obtain synthetic variables for use as instruments in IV estimation. By their very nature, instruments based on synthetic variables are exogenous. Furthermore, they can provide relatively high levels of correlation with the endogenous variable. In this paper we consider two situations of interest: First, the case where there are no clear candidates for instrumentation and the instruments are comprised of purely synthetic variables; second, the case when there are substantive but weak instruments that can be enhanced by the addition of synthetic variables. The approach proposed is illustrated with an empirical example.

The thermal-electric logic circuit (TELC) concept is a possible way to overcome the scaling down problems of the conventional CMOS integrated circuits having very complex structure nowadays. The basic component of the TELC is the metal-insulator transition (MIT) switch, which is an extremely simple bulk type device. This work evaluates the effect of the scaling down on the speed of the VO2 thermal-electric switch. Different types (lateral and vertical) of VO2 resistors have been produced by laser ablation. The measured switching time strongly correlates with the characteristic size of the device. The energy consumption (power-delay product) of the scaled-down switching device estimated as a sum of the energy needed for heating the thermal diffusion length sized environment of the device, heating the device itself and the latent heat of phase transition of VO2.

This article uses data from the Occupational Employment Statistics survey to examine trends in labor market outcomes for registered nurses from 2002 to 2015. Special attention is paid to the 2007–10 period, which encompasses the Great Recession. The analysis reveals that nursing employment and wages increased during the recession, lending support to previous research suggesting that nursing is a recession-proof, countercyclical profession.

Rationale Although there is considerable interest in machine learning (ML) algorithms to improve patient care, implementation of these algorithms into practice has been limited. Our team developed and validated a deep learning algorithm to predict respiratory failure requiring mechanical ventilation in patients in the intensive care unit (ICU), including those with COVID-19. To help optimize implementation of this tool, we developed and disseminated a survey assessing ICU physician perspectives on the acceptability and feasibility of this tool at our institution. Methods We distributed an 8-item survey to 99 critical care trainees and faculty at our institution via email. The survey consisted of 6 multiple choice and 2 free response questions, with an ordinal scale of 1-5 used in perception-based questions. The survey was designed in accordance with international recommendations for web-based surveys. Our survey was reviewed for completeness by a team of critical care, machine learning, and implementation science experts. Data were collected over a 2- week period in May of 2021. This survey was anonymous and exempt from IRB review. Results Fifty-three critical care physicians (53.5% of providers contacted) started the survey, and of these, 88.7% (47/53) completed the survey. Fifty-nine percent (n=31) of respondents were attendings, 36% (n=19) fellows, and 3.7% (n=2) residents. Baseline knowledge of ML was low (mean= 2.40/5), with only 7.5% (n=4) of respondents rating their knowledge as a 4 or 5. Fifteen percent (n=8) had knowingly used an ML-based tool in their clinical practice. Confidence in predicting the need for mechanical ventilation due to COVID-19 (mean=3.57/5) was slightly lower than for respiratory failure due to all other causes (mean=3.89/5). Overall willingness to utilize an ML-based algorithm was favorable (mean=3.32/5). Factors most likely to increase likelihood of utilization were “high quality evidence that it outperformed trained clinicians” (mean=4.28/5), “transparency of the data utilized” (mean= 4.13/5), and “limited workflow interruption” (mean=4.09/5). Shared concerns from participants included “alarm fatigue” and “workflow interruption.” Conclusion The results suggest that ICU physicians have had limited exposure to ML-based tools, but feel such a tool would be beneficial in the context of predicting need for mechanical ventilation in ICU patients and those with COVID-19. Evidence of the tool's efficacy and data transparency were high priorities for respondents, and there was concern over workflow interruptions. This survey provided a baseline assessment of physician acceptance of a novel ML-based tool, which will be crucial in optimizing its implementation into clinical practice at our institution.

Within the context of experimental pharmacology, some criteria are discussed for estimating the potential of natural products with possible pharmacological activity for the treatment of hypertension. This disorder has great epidemiological impact in Colombia as well as elsewhere. Discovery of these products can be accomplished by use of accessible pharmacological tests such as the following: developing models of arterial hypertension in the laboratory rat, in vitro tests, in vivo tests and microscopic analysis. Suitable protocols associated with these techniques can capture valuable information about possible effects on hypertension during the evaluation phase of a natural product.

GH-releasing peptide-6 (GHRP-6) is a potent GH secretagogue that releases GH by uncertain mechanisms. To assess whether GHRH is required for GH release by GHRP-6 in humans, we used the specific antagonist to GHRH (N-Ac-Tyr1,D-Arg2)GHRH(1-29)NH2 (GHRH Ant). We have previously shown that GHRH-Ant (400 microg/kg) blocked the GH response to 0.33 and 3.3 microg/kg boluses of GHRH by 95% and 81%, respectively. Nine healthy men between the ages of 20 and 30 yr were studied on two occasions. They received either saline or GHRH-Ant (400 microg/kg, i.v.) at 0840 h, followed by GHRP-6 (1 microg/kg, i.v. bolus) at 0900 h. Blood was sampled every 10 min from 0800-1100 h. GH responses were measured as the maximal increase over the baseline GH concentration and as the area under the curve. GHRH-Ant eliminated most of the GH response to GHRP-6 [maximal increase over the baseline GH concentration, 33.8 +/- 4.8 vs. 6.2 +/- 1.8 microg/L (mean +/- SEM; P < 0.0001); area under the curve, 1701 +/- 278 vs. 376 +/- 113 microg/min x L (P < 0.001)]. These data show that endogenous GHRH is necessary for most of the GH response to GHRP-6 in humans.

The effects of missing values for a confounding variable are investigated in the setting of case-control studies in which, for simplicity, the effect of one binary risk factor and one categoric confounding variable on disease risk is under investigation. Some ad hoc techniques with which to deal with missing values are examined under different assumptions about the missing-data mechanism. Examples are given to illustrate that the magnitude of the bias that is introduced by applying an inadequate procedure can be large under circumstances that occur frequently in empiric research. This is true even for so-called complete case analysis, i.e., when only data on subjects with complete information are used. Appropriate bias corrections are derived. Making use of data on those subjects who are neglected in complete case analysis by creating an additional category always results in biased estimation. An alternative is to allocate these subjects to the cells of the contingency table in an appropriate manner. This approach yields consistent estimates if the data are missing at random. Choosing an appropriate method for dealing with missing values always requires some knowledge of why the data are missing. This suggests that investigators should carry out validation studies to understand whether the missing values occur randomly across the study population or occur more frequently in specific subgroups.

Abstract James Estep's integration of Vygotsky's work on the Zone of Proximal Development into Christian education and pedagogy falls short of a distinctly evangelical form of integration. Using Ken Badley's schemata of Integration of Faith and Learning, this article distinguishes Estep's “paradigmatic” integration from a more thoroughgoing “perspectival” integration. Perspectival integration best displays the connections between Vygotsky's Zone of Proximal Development and evangelical thinking by using the divine accommodation of John Calvin, as described in the work of Arnold Huijgen.

We have calculated an ab initio nonadiabatic polarization potential for the e-H/sub 2/ system using a procedure that is based on the variational method. The importance of various multipole contributions to this potential has been investigated and the dipole approximation found to be accurate for this system. When used in scattering calculations with accurate representations of the static and exchange components of the interaction potential, the new polarization potential is found to yield total integrated e-H/sub 2/ cross sections that are in very good agreement with results of recent measurements and of optical-potential calculations.

The conditions for the appearance of a sharp laser transition are formulated in terms of a scaling limit, involving vanishing cavity loss and light-matter coupling, k → 0, g → 0, such that g2/k stays finite. It is shown analytically that in this asymptotic parameter domain, and for pump rates above the threshold value, the photon output becomes large in a sense that is specified, and the photon statistics becomes strictly Poissonian. Numerical examples for the case of a two-level and a three-level emitter are presented and discussed in relation to the analytic result.

BACKGROUND
Neurophysiological techniques are increasingly used in examination of urinary incontinence. The purpose was to measure the activity in the perineal muscles in women with urinary stress incontinence and compare with normal subjects by using quantitative EMG methods.
METHODS
Twenty-four incontinent women and seven normal subjects were evaluated urodynamically and with quantitative EMG analysis of interference pattern and single fiber measurements. The recordings were made in the pubo rectal and the external anal sphincter muscle with empty urinary bladder at rest and maximal voluntary contraction as well as during cystometry.
RESULTS
The incontinent women had a denser interference pattern in the anal sphincter at rest but no differences at maximal activation compared to the reference group. No differences in interference pattern were noted between the two groups in the pubo rectal muscle. Fiber density in the external anal sphincter muscle was increased in the patient group (2.01 compared to 1.33, p<0.01). The urethral pressures at rest and activation were higher in the normal subjects (p<0.05). The normal subjects showed a denser interference pattern in the external anal sphincter muscle during cystometry (p<0.05).
CONCLUSIONS
Quantitative analysis of the interference pattern and fiber density in the perineal muscles in incontinent women showed a denser interference pattern at rest and increased fiber density. Both observations indicate a peripheral nerve lesion. Furthermore, the interference pattern showed signs of reduced central activation in the incontinent women during cystometry.

The present paper is based on our graduate lectures in condensed-matter physics. We found that the mean-field solution of the Hubbard model is an excellent tool to stimulate students’ reflections towards the treatment of realistic magnetic interactions. We show by detailed analytical and numerical calculations how to find the mean-field solution of the model on a square lattice. We then interpret the physical implications of the ground-state magnetic phase diagram in terms of the electron density and the ratio between the Coulomb repulsion and the electron-structure bandwidth.

The upper surface of a large gas bubble rising steadily through liquid under gravity is a statically unstable interface, and if the liquid were stationary small sinusoidal disturbances to the interface with wavelength exceeding the critical value Λc determined by surface tension would grow exponentially. The existence of the deforming motion of the liquid adjoining the interface of a steadily rising bubble changes the nature of the problem of stability. It is shown that a small sinusoidal disturbance of the part of the interface that is approximately plane and horizontal remains sinusoidal, although with exponentially increasing wavelength. The amplitude of such a disturbance increases, from the instant at which Λ = Λc until Λ becomes comparable with the radius of curvature of the interface (R), and the largest amplification occurs for a disturbance whose initial wavelength is approximately equal to Λc. With a plausible guess at the disturbance amplitude and wavelength at which bubble break-up due to nonlinear effects is inevitable, it is possible to obtain an approximate numerical relation between the initial magnitude of the disturbance and the maximum value of R for which a bubble remains intact. This relation applies both to a spherical-cap bubble in a large tank and a bubble rising in a vertical tube in which the liquid far ahead of the bubble is stationary. The few published observations of the maximum size of spherical-cap bubbles are not incompatible with the theory, but lack of information about the magnitude of the ambient disturbances in the liquid precludes any close comparison.

Due to the COVID-19 pandemic, the sales of fast-food businesses have dropped sharply. Customer satisfaction has always been one of the key factors for the sustainable development of enterprises. However, in the fast-food restaurant business, gaining the knowledge of customer satisfaction is one of the critical tasks. Moreover, text reviews in social media have become one of important reference sources for customers’ decisions in buying services and products. Therefore, the main purpose of this study is to explore whether customer voices from social media reviews are different during the COVID-19 outbreak and to propose a new method to reduce interpersonal contact when collecting data. A text mining scheme which includes least absolute shrinkage and selection operator (LASSO) and decision trees (DT) are presented to discover the essential factors for customers to increase their satisfaction from unstructured online customer reviews. Finally, three real world review sets were employed to validate the effectiveness of the presented text mining scheme. Experimental results can help companies to properly adapt to similar epidemic situations in the future and facilitate their sustainable development.

This study aims to identify and analyze how the influence of the quality of human resources and the implementation of the policies of the PUPR Office of Bantaeng Regency together on the formation of spatial patterns in Bissappu District, Bantaeng Regency. The analytical method used in this study is testing the data obtained based on times series data or time to time based on data collected over a five (5) year time interval. Tests in this study were conducted with the correlation model. The correlation used includes a simple linear correlation method and then multiple correlation tests are carried out. Multiple correlation is a statistical method used to determine the general pattern of relationships that affect between variables. received is then analyzed manually according to the analytical procedures in the study. Where in this study has more than one independent variable. Looking at the results of the above calculation, the influence of human resources (X1) on the formation of spatial patterns (Y) has a moderate correlation, namely 0.421 where rcount rtable = 0.878 at a significance level of alpha 0.05 then H0 is accepted and H1 is rejected. This proves that improving the quality of human resources (employees) does not have a significant relationship with the formation of spatial patterns. The results of the analysis of correlation calculations in chapter IV show that policy implementation (X2) has a very strong relationship with the formation of spatial patterns (Y). The successful implementation of the IMB service policy implementation, the stronger the influence on the formation of spatial patterns where rcount = 0.9805 is greater than rtable = 0.878 at a significance level of 5% where H0 is rejected and H1 is accepted. The results of testing and calculation of correlation analysis on the Variable of improving the quality of human resources (employees) (X1) and Policy Implementation (X2) together have a very strong relationship to the formation of spatial patterns of 0.9801. Where if Rcount is greater than Rtable of 0.878, at the alpha significance level is 0.05, then H0 is rejected and H1 is accepted
