Constant switching frequency hysteresis controller for VSI fed Induction Motor drive using current error space phasor approach

A simple current error space vector (CESV)based constant switching frequency hysteresis controller for two level voltage source inverter fed Induction Motor(IM) drives is proposed in this paper. The main advantages of space phasor based hysteresis controllers such as fast dynamic response, adjacent voltage vector switching can be seen in the proposed controller. In addition to these, switching frequency variation can be eliminated substantially. The stator voltages estimated from the current ripple, calculation of vector switching times and voltage error vectors are used for the current error boundary calculation. The proposed controller selects only those inverter voltage vectors of the present sector which are adjacent to the machine voltage vectors for the entire range of operation to reduce current error. Bus clamping space vector pulse width modulation(BCSVPWM) is used for vector selection logic where only one zero state is used in a sub cycle of total switching time period. The proposed hysteresis controller based inverter fed drive scheme is simulated using SIMULINK toolbox of MATLAB for steady state and transient performance.
Scattering of multi identical object

Based on the extend boundary condition method. The scattering matrix of single axisymmetric object is obtained. Some examples of the scattering prosperity of multi axisymmetric object are calculated. While considering the addition method of vector spherical harmonic function and the rotation method of wave function, the scattering matrix of multi-axisymmetric objects are obtained. Numerical results showed that the scattering translation matrix method have its advantages in calculating the scattering properties of multi-axisymmetric objects.
The Increasing Burden of Alcoholic Liver Disease on United Kingdom Critical Care Units: Secondary Analysis of a High Quality Clinical Database

Objectives To investigate the effect of increasing alcohol consumption on the number of admissions to adult, general critical/intensive care units (ICUs) in England and Wales with alcoholic liver disease, their case mix, mortality, and impact on critical care and hospital activity by extrapolating from admissions to ICUs over the last 10 years. Methods Secondary analysis of a high quality clinical database from a national clinical audit using data from 385,429 admissions to174 ICUs in England and Wales between December 1995 and July 2005, of which 4219 (1.1%) had alcoholic liver disease. The extrapolated total number of admissions with alcoholic liver disease and total number of ICU bed-days occupied were calculated. Changes over time in the case mix (age, sex and APACHE II and ICNARC risk prediction models), mortality at ultimate discharge from acute hospital, and length of stay in ICU and in hospital were explored. Results The percentage of ICU admissions with alcoholic liver disease increased from 0.65% in 1996 to 1.35% in 2005, but the case mix remained similar. Mortality decreased and length of stay increased over this period. The extrapolated total number of admissions to all 229 adult, general critical care units in England and Wales increased from 550 in 1996 to 1513 in 2005, and the extrapolated total number of bed-days occupied by these admissions increased from around 3100 to over 10,000. Conclusions Admissions to ICUs in England and Wales with alcoholic liver disease tripled over the 10-year period from 1996 to 2005. The continuing increase in alcohol consumption means that this trend is likely to continue.
Exploration Methodology for 3D Memory Redundancy Architectures under Redundancy Constraints

Redundancy repair is a commonly-used technique for memory yield improvement. In order to ensure high repair efficiency and final product yield, it is necessary to explore and develop the memory redundancy architecture carefully. However, due to the different failure distributions of memory arrays and various design constraints of memory architectures, it is difficult to explore the efficiency of the memory architecture thoroughly. In this paper, we propose a redundancy architecture exploration methodology to find the redundancy architecture with highest repair rate under redundancy constraints. Given a set of design constraints, failure distributions, and memory architectures, our methodology can explore at least 3(log2M* log2N* log2S) redundancy architectures systematically, where M, N, and S are the address sizes of memory row and column in a die, and the number of slices in the memory cube, respectively. In our experiments, the repair rates of 10 different 3D redundancy architectures with 3 different redundancy analysis algorithms in a given failure pattern distribution are simulated. The experimental result shows that the difference of the repair rates between the most efficient and least efficient memory redundancy architectures is up to 49.42%.
Induction of somatic hypermutation by antigen‐specific B cell receptors in the human BL2 cell line

The role of the B cell antigen receptor in the induction of somatic hypermutation is presently unclear. We established stable transfectants of the human BL2 cell line expressing hen‐egg lysozyme‐specific IgM or IgA and compared their ability to induce somatic hypermutation of the endogenous rearranged heavy‐chain gene. We found that IgM and IgA were both able to induce somatic hypermutation in an antigen dose‐independent manner. The mutations displayed most of the characteristics of somatic hypermutation in vivo. Notably, some replacements introduced stop codons in the coding region. Our data suggest that class‐switched memory B cells may undergo somatic hypermutation. They also suggest that the transmembrane/cytoplamic domains of the class‐switched isotypes modulatethe signaling and down‐modulation activities of the BCR in an antigen dose‐dependent manner.
Co-Movement and Integration Among Stock Markets : A Study of 14 Countries

This paper explored the comovement among 14 stock markets, namely BSE, BVSP, FTSE -100, Hang Seng, JKSE, KSE, KSE (Korea), MXX, NASDAQ, NIKKI, RTS, SSE, SSMI, and TSEC. Daily index of all stock markets covering a period from January 1, 1998 to January 31, 2017 were used. The correlation analysis showed that BSE remained somewhat positively correlated with Hang Seng (0.45), FTSE-100 (0.32), MXX (0.27), NASDAQ (0.24), and BVSP (0.23). Results of Granger causality test indicated that the returns of BSE were dependent on BVSP, FTSE - 100, and MXX only. Outcome of Johansen cointegration test indicated that there was a long run relationship among selected stock markets. From this present study, FIIs (foreign institutional investors), individual investors, institutional investors, public investors, and HNIs (high net worth individuals) will be benefited. All these stakeholders can take their decisions for their investments in the overseas markets by looking at the short-term and long-term integration of BSE with other selected markets.
Testosterone deficiency and severity of erectile dysfunction are independently associated with reduced quality of life in men with type 2 diabetes

Erectile dysfunction (ED) and low testosterone levels are common in men with type 2 diabetes (T2D). We have investigated the impact of testosterone on quality of life (QoL) in diabetic men with ED. Men with ED were identified within a study cohort of 355 men with T2D. All subjects completed SF‐36 health and Androgen Deficiency of the Aging Male questionnaires. Total tesosterone (TT), bioavailable testosterone (BT) and sex hormone‐binding globulin levels of study participants were measured and free testosterone levels were calculated (cFT). A subgroup of 126 ED patients completed the International Index of Erectile Function‐5 (IIEF‐5) questionnaire. Linear regression analyses were corrected for age, body mass index (BMI), glycosylated haemoglobin (HbA1c), smoking, alcohol consumption and cardiovascular disease (CVD). Total SF‐36 scores significantly and positively correlated with TT levels (r = 0.219, p = 0.001), BT levels (r = 0.199, p = 0.004) and cFT levels (r = 0.185, p = 0.007) among men with ED. These trends were strengthened after adjusting for age, BMI, HbA1c, smoking, alcohol consumption and CVD (TT r = 0.359, p = 0.015; BT r = 0.354, p = 0.024 and cFT r = 0.354, p = 0.024). IIEF‐5 scores significantly correlated inversely with TT (r = 0.546, p = 0.001), BT (r = 0.506, p = 0.004) and cFT levels (r = 0.532, p = 0.001). A positive linear relationship was observed between IIEF‐5 scores and total SF‐36 score (r = 0.491, p = 0.003). Patients who reported having ED had an average SF‐36 score of 9.1% less than those without ED (p < 0.001). Lower testosterone and greater severity of ED independently correlated with poorer physical function, social function, vitality and decline in general health domains of the SF‐36. This is the first study to report that testosterone deficiency and severity of ED are both independently associated with reduced QoL in men with T2D. Furthermore, ED and low testosterone are markers of poor health which impact on an individual's self‐perception of their health status.
A Comparison of Patient Self-administered and Investigator-administered Measurement of Quality of Recovery Using the QoR-40

A 40-item questionnaire (the QoR-40) had been previously developed to measure five dimensions of quality of recovery after anaesthesia and surgery. Each of the 40 items is rated on a scale of 1 to 5, with a maximum score of 200. In this study we compared patient self-administered with investigator-administered QoR-40. We studied 62 postoperative patients within 48 hours of their surgery. Agreement between the two methods was analysed using the intraclass correlation coefficient, bias and limits of agreement. There was strong correlation between the investigator-administered and patient self-administered QoR-40 scores, intraclass correlation coefficient 0.86 (95% CI: 0.77 to 0.92), P<0.001. The bias and limits of agreement were 3.1 and -22 to 28, respectively. There were 10 (16%) patient self-administered questionnaires that were not completed at first attempt. The time to complete the questionnaire when investigator-administered was 253 (16) s [mean,(SD)], and on first attempt for patients was 362 (19) s, P<0.001. The QoR-40 is as valid measure of postoperative recovery when administered with the assistance of an investigator as compared with the patient self-administered version. Investigator-administered measurement of the QoR-40 is a more efficient use of resources, as complete and more timely data are collected.
Expression of vascular permeability factor (vascular endothelial growth factor) and its receptors in endometrial carcinoma

Solid tumors, including endometrial carcinomas, must induce a vascular stroma to grow beyond a minimal size. The mechanisms responsible for angiogenesis in endometrial carcinoma, however, are not well defined. Vascular permeability factor (VPF), also known as vascular endothelial growth factor (VEGF), is a multifunctional cytokine that is an important regulator of tumor angiogenesis. We evaluated VPF/VEGF mRNA and protein expression, as well as VPF/VEGF receptor mRNA expression, in endometrial carcinoma.
Developing a Scale for Schools as Learning Organizations towards Quality Culture

Abstract Being open to learning understanding is essential for increasing service quality. The study aims todevelop a scale that measures whether secondary school institutions show the features of a learning organization. 297teachers participated in this research process. Data was analyzed by using statistical analysis. The factor loads for the30 questions in scale have been found satisfactory, and construct validity was ensured without adding or omittingquestions. ‘Duties and responsibilities’, ‘dialogue, sharing and teamwork’, ‘development, research and continuouslearning’, and ‘organization learning obstacles’ are the subdimensions as a result of the explanatory factor analysis.This scale will play a significant role in educational institutions that are trying to become learning organizations.
Eating psychopathology and personality in eating disorders

Summary Objective - The question of how many psychopathologic factors are involved in Anorexia Nervosa (AN) and Bulimia Nervosa (BN) has no definite answer. The combination of psychopathology and personality research may shed a light upon the determinants of eating pathology. Methods - The study consists inthe administration of the Temperament and Character Inventory (TCI) and the Eating Disorder Inventory 2 (EDI-2) to 95 outpatient anorectic women (50 restrictive and 45 binge-purging) and to 92 bulimic outpatientwomen (78 with and 14 without purging behaviours). The respective scores of each DCA subgroup are compared. Results - Restricter anorectics are characterised by lower novelty seeking on respect to all the other groups and by a higher self-directedness on respect to bingeing-purging anorectics and purging bulimics. Alsopsychopathologic differences between restricter anorectics and the other groups are extensive. Bingeing-purging anorexia shares many traits with bulimia. Conclusions - In their complex, data suggest and in-deep study aimed to a possible re-classification of EDs which would take impulsiveness in greater consideration. The differences in temperament and character traits may partially be responsible of the repression or discontrol of impulsive eating behaviours in different ED subtypes.

Feature extraction based on time-frequency and Independent Component Analysis for improvement of separation ability in Atrial Fibrillation detector

Due to redundancy of over-dimensioned information, observed often in originally recorded biomedical signals, feature extraction and selection has become focus of much researches connected with biomedical signal processing and classification. Mixed new feature vector combined from time-frequency signal representation (obtained after wavelet transform) and Independent Component Analysis (ICA) applied for non-stationary signals is proposed as a preliminary stage in ECG waveform classification for patients with Atrial Fibrillation (AF). Discrete fast wavelet transform coefficients parameters including energy and entropy measures and components extracted as a result of FastICA algorithm implementation after optimization gave the best classifier performance of whole AF ECG classifier system. System was positively verified on the set of clinically classified ECG signals for control and atrial fibrillation (AF) disease patients taken from MITBIH data base. The measures of specificity and sensitivity computed for the set of 20 AF and 20 patients from control group divided into learning and verifying subsets were used to evaluate presented pattern recognition structure. Different types of wavelet basic functions for feature extraction stage and kernels for SVM classifier structure calculation were tested to find the best system architecture. Obtained results showed, that the ability of generalization and separation for enriched feature extraction based system increased, due to selectively choosing only the most representative features for analyzed AF detection problem.
Implementation of a 5&#215;5 trits multiplier in a quasi-adiabatic ternary CMOS logic

Adiabatic switching is one technique to design low power digital IC. In order to diminish its expensive silicon area requirements an adiabatic ternary logic is proposed. A 5×5 trits (ternary signals) multiplier has been designed and implemented using this logic in a 0. 7µm CMOS technology. Results show a satisfactory power saving and a decreasing of the area needed with respect to an adiabatic binary one.
Probing Trypanosoma cruzi biology with DNA microarrays

The application of genome-scale approaches to study Trypanosoma cruzi–host interactions at different stages of the infective process is becoming possible with sequencing and assembly of the T. cruzi genome nearing completion and sequence information available for both human and mouse genomes. Investigators have recently begun to exploit DNA microarray technology to analyze host transcriptional responses to T. cruzi infection and dissect developmental processes in the complex T. cruzi life-cycle. Collectively, information generated from these and future studies will provide valuable insights into the molecular requirements for establishment of T. cruzi infection in the host and highlight the molecular events coinciding with disease progression. While the field is in its infancy, the availability of genomic information and increased accessibility to relatively high-throughput technologies represents a significant advancement toward identification of novel drug targets and vaccine candidates for the treatment and prevention of Chagas' disease.
Analyzing the costs and benefits of distributed solar energy in Virginia (USA): a case study of collaborative energy planning

Solar energy policy has become controversial in Virginia and many other states. Proponents point to its environmental, public health, and economic development benefits, and argue that it can help support electric grid operations. However, detractors, including many electric utilities, contend that the growth of customer-owned, distributed solar energy systems will create costs that must be passed on to ratepayers. This article presents a case study in which the authors led a multi-faceted Solar Stakeholder Group to evaluate the costs and benefits of distributed solar energy in Virginia. We examine this project in the context of collaborative planning theory, finding that it created shared learning among participants and facilitated greater understanding of opposing viewpoints, but did not produce a consensus vision for future action. We also note some of the Stakeholder Group's broader contributions to the ‘value-of-solar’ debate and discuss its implications for future distributed solar energy efforts in Virginia.
Orthorhombic polymorph of 4-[(1H-benzimidazol-1-yl)methyl]benzoic acid

We reported recently the first polymorph of the title compound [Kuai & Cheng (2011a ▶). Acta Cryst. , E67, o2787]. A second polymorph of the title compound, C15H12N2O2, was unexpectedly obtained by the hydrothermal reaction of the title compound with manganese chloride in the presence of potassium hydroxide at 413 K. The benzimidazole ring system is almost planar, with a maximum deviation from the mean plane of 0.015 (2) Å. The benzimidazole and benzene rings are inclined at a dihedral angle of 79.00 (1)°. In the crystal, adjacent molecules are connected through O—H⋯N hydrogen bonds into a one-dimensional chain along the [001] direction.
Lipochitin Oligosaccharides Immobilized through Oximes in Glycan Microarrays Bind LysM Proteins

Glycan microarrays have emerged as novel tools to study carbohydrate–protein interactions. Here we describe the preparation of a covalent microarray with lipochitin oligosaccharides and its use in studying proteins containing LysM domains. The glycan microarray was assembled from glycoconjugates that were synthesized by using recently developed bifunctional chemoselective aminooxy reagents without the need for transient carbohydrate protecting groups. We describe for the first time the preparation of a covalent microarray with lipochitin oligosaccharides and its use for studying proteins containing LysM domains. Lipochitin oligosaccharides (also referred to as Nod factors) were isolated from bacterial strains or chemoenzymatically synthesized. The glycan microarray also included peptidoglycan‐related compounds, as well as chitin oligosaccharides of different lengths. In total, 30 ligands were treated with the aminooxy linker molecule. The identity of the glycoconjugates was verified by mass spectrometry, and they were then immobilized on the array. The presence of the glycoconjugates on the array surface was confirmed by use of lectins and human sera (IgG binding). The functionality of our array was tested with a bacterial LysM domain‐containing protein, autolysin p60, which is known to act on the bacterial cell wall peptidoglycan. P60 showed specific binding to Nod factors and to chitin oligosaccharides. Increasing affinity was observed with increasing chitin oligomer length.
Visualizations of user data in a social media enhanced web-based environment in higher education

In this article, we introduce the results of a study concerning user data visualizations in the context of the TUT Circle, a social media enhanced web service for learning, networking, and communication at the Tampere University of Technology (TUT). Well-designed visualizations can provide valuable insight into student activity and participation in an online course, and therefore support both teachers' and students' strategic decision making. We found social network analytics and visualizations useful in providing information to improve the pedagogical practices of online courses, as well as the students' overall engagement in their studies and study lives. However, to be useful, the visualizations need to have enough hints so that the users can interpret the different elements in them in the right way.
Gene Expressions for Signal Transduction under Acidic Conditions

Although it is now well known that some diseased areas, such as cancer nests, inflammation loci, and infarction areas, are acidified, little is known about cellular signal transduction, gene expression, and cellular functions under acidic conditions. Our group showed that different signal proteins were activated under acidic conditions compared with those observed in a typical medium of around pH 7.4 that has been used until now. Investigations of gene expression under acidic conditions may be crucial to our understanding of signal transduction in acidic diseased areas. In this study, we investigated gene expression in mesothelioma cells cultured at an acidic pH using a DNA microarray technique. After 24 h culture at pH 6.7, expressions of 379 genes were increased more than twofold compared with those in cells cultured at pH 7.5. Genes encoding receptors, signal proteins including transcription factors, and cytokines including growth factors numbered 35, 32, and 17 among the 379 genes, respectively. Since the functions of 78 genes are unknown, it can be argued that cells may have other genes for signaling under acidic conditions. The expressions of 37 of the 379 genes were observed to increase after as little as 2 h. After 24 h culture at pH 6.7, expressions of 412 genes were repressed more than twofold compared with those in cells cultured at pH 7.5, and the 412 genes contained 35, 76, and 7 genes encoding receptors, signal proteins including transcription factors, and cytokines including growth factors, respectively. These results suggest that the signal pathways in acidic diseased areas are different, at least in part, from those examined with cells cultured at a pH of around 7.4.
#MAGA or #TheResistance: Classifying Twitter users' political affiliation without looking at their words or friends

Previous NLP work attempting to classify Twitter users’ political afﬁliation focused on lexical features and information users’ social networks. However, sociolinguistic work on the expression of political identity has found that sub-lexical features also re-ﬂc political identity. This study shows that it is possible to achieve above-chance clas-siﬁcation of Twitter users based on only three features: how much punctuation and capitalization an account uses and what proportion of their tweets are replies.
