Simulation of a Space Vector PWM Controller For a Three-Level Voltage-Fed Inverter Motor Drive

Multilevel voltage-fed inverters with space vector pulse width modulation strategy are gained importance in high power high performance industrial drive applications. This paper proposes a new simplified space vector PWM method for a three-level inverter fed induction motor drive. The three- level inverter has a large number of switching states compared to a two-level inverter. In the proposed scheme, three-level space vector PWM inverter is easily implemented as conventional two-level space vector PWM inverter. Therefore, the proposed method can also be applied to multilevel inverters. In this work, a three-level inverter using space vector modulation strategy has been modeled and simulated. Simulation results are presented for various operation conditions using R-L load and motor load to verify the system model
The Vibrio cholerae virulence regulatory cascade controls glucose uptake through activation of TarA, a small regulatory RNA

Vibrio cholerae causes the severe diarrhoeal disease cholera. A cascade of regulators controls expression of virulence determinants in V. cholerae at both transcriptional and post‐transcriptional levels. ToxT is the direct transcription activator of the major virulence genes in V. cholerae. Here we describe TarA, a highly conserved, small regulatory RNA, whose transcription is activated by ToxT from toxboxes present upstream of the ToxT‐activated gene tcpI. TarA regulates ptsG, encoding a major glucose transporter in V. cholerae. Cells overexpressing TarA exhibit decreased steady‐state levels of ptsG mRNA and grow poorly in glucose‐minimal media. A mutant lacking the ubiquitous regulatory protein Hfq expresses diminished TarA levels, indicating that TarA likely interacts with Hfq to regulate gene expression. RNAhybrid analysis of TarA and the putative ptsG mRNA leader suggests potential productive base‐pairing between these two RNA molecules. A V. cholerae mutant lacking TarA is compromised for infant mouse colonization in competition with wild type, suggesting a role in the in vivo fitness of V. cholerae. Although somewhat functionally analogous to SgrS of Escherichia coli, TarA does not encode a regulatory peptide, and its expression is activated by the virulence gene pathway in V. cholerae and not by glycolytic intermediates.
The effect of corporate governance regulations on firm value : New Zealand evidence

Manuscript Type: Empirical Research Question/Issue: This paper examines the effect that compliance with corporate governance regulations has on the value of New Zealand firms. Research Findings/Insights: From a sample of 70 New Zealand firms over the period 2000 to 2007, we find that firms that have a high level of compliance with corporate governance regulations have higher value to investors. Theoretical/Academic Implications: Consistent with agency theory, this paper documents that voluntary compliance with corporate governance regulations and/or guidelines increases the effective monitoring of firm performance. Agency costs associated with the control of managerial discretion are mitigated as a result of this voluntary compliance. Practitioner/Policy Implications: This study will be of interest to those who set regulations and/or guidelines that aim to promote good corporate governance practice.
Assessment of the quality of reporting in randomised controlled trials of acupuncture in the Korean literature using the CONSORT statement and STRICTA guidelines

Objectives This study aims to assess the completeness of reporting of randomised controlled trials (RCTs) of acupuncture in the Korean literature. Design Systematic review. Methods We searched 12 Korean databases and 7 Korean journals to identify eligible RCTs of acupuncture published from 1996 to July 2011. We used the Consolidated Standards of Reporting Trials (CONSORT) checklist for parallel RCTs and the revised STandards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) to assess the quality of reporting in Korean RCTs. We compared the completeness of reporting of CONSORT and STRICTA items in RCTs published in two time periods (1996–2004 referred to as the early period and 2005–2011 referred to as the late period). Results We analysed 146 eligible RCTs using the CONSORT statement concerning RCTs of both needling and non-needling acupuncture and the STRICTA guidelines for 90 trials of needling acupuncture. Among the 103 RCTs in the late period, the proportion of RCTs that completely reported the CONSORT items of outcome definition (15.5%), sample size calculation (2.9%), randomisation (56%), allocation concealment (5.8%), implementation of allocation (11.7%), outcome assessor blinding (20.3%), flow of participants (25.2%), number of participants analysed (19.4%), ancillary analyses (0.0%), adverse events (24.3%), generalisability of findings (1.9%) and overall evidence (32.0%) remained small. Among the 61 RCTs of needling acupuncture in the late period, the STRICTA items of setting/context (24.6%) and practitioner background (27.9%) showed incomplete reporting. The completeness of reporting improved over time in several CONSORT and STRICTA items. Conclusions The completeness of reporting of Korean RCTs of acupuncture was suboptimal according to the CONSORT and revised STRICTA statements. Trial authors and journal editors should use the CONSORT statement and STRICTA guidelines for transparent reporting in Korean RCTs of acupuncture. The endorsement of the CONSORT and revised STRICTA statements in author instructions is also required.
Performance of Digital Modulation in Double Nakagami-m Fading Channels with MRC Diversity

In this paper, we derive the average bit error probability (BEP) for common digital modulation schemes and the outage probability of double Nakagami-m channels with MRC diversity. First, the probability density function (PDF) and moment generating function (MGF) of received signal with maximal ratio combining (MRC) receiver diversity are computed. The derived MGF results are simplified in terms of a generalized hypergeometric function 2F0. The derived BEP expressions find applications in existing wireless systems such as satellite mobile communication system, mobile-to-mobile communication system and multiple-input multiple-output (MIMO) wireless communication system. In addition, the obtained general MGF expression considers combined Rayleigh × Nakagami-m, double Rayleigh, single Rayleigh, single Nakagami-m, and non-fading or additive white Gaussian noise (AWGN) channels as special cases. The simulation results agree well with the theoretical results.

Firm Level Factors Affecting Liquidity – The Swedish Stock Market

Purpose: The purpose of this study is to further look at which firm-adjustable factors affect the liquidity of a firm's stock in the Swedish stock market. We also want to determine which out of these suggested factors have a significant effect on liquidity across different proxies of liquidity. Finally we aim to determine whether our findings are consistent with previous research findings. Methodology: A quantitative approach with the interpretation of the results from panel data regressions. Theoretical framework: Liquidity Capital Asset Pricing Model (LCAPM) Empirical foundation: A sample of 433 firms during the time period 2000-2014 Conclusions: We come to the conclusion that the firm’s assets liquidity and the ownership structure, more specifically the cash and cash equivalents and the free floating shares, have a positive relationship with liquidity for firms on the Swedish Stock market. These findings are consistent with other studies in other markets. Our data did however not provide significant results to establish a relationship between liquidity and capital structure or dividend payout policies.
Tourist Satisfaction in Kashmir: An Empirical Assessment

Tourist satisfaction is one of the most important concerns of competitive destinations as it considerably influences the tourist’s choice of a destination, the consumption of products and services and the decision to visit the destination in the future. With the increasing role of tourism in the global economy and growing competition in the global tourism market, the importance of enhancing the satisfaction level of tourists is being recognized as a way to expand and maintain a large and loyal customer base for long-term success. Satisfied tourists bring success to the tourism business. They are likely to revisit and recommend the destination to their families and friends. On the other hand, dissatisfied tourists may not return to the same destination and may not recommend it to other tourists. Even worse, dissatisfied tourists may express negative comments about a destination and damage its market reputation. In view of the growing importance of tourist satisfaction for tourism promotion, present study is an attempt to measure the satisfaction level of tourists in Kashmir Valley. Based on data gathered from three hundred forty (340) tourists, the study brought to light four interpretable service quality dimensions for tourism services: Assurance, Tangibility, Responsiveness and Reliability. Findings are analyzed and suggestions for improving tourists’ satisfaction have been discussed.
Impact of deprenyl and tocopherol treatment on Parkinson's disease in DATATOP patients requiring levodopa

The Deprenyl and Tocopherol Antioxidant Therapy of Parkinsonism (DATATOP) trial was designed to test outcomes from treatment with 10 mg of deprenyl and/or 2,000 mg of tocopherollday in 800 untreated patients with Parkinson's disease. The need of subjects for symptomatic treatment with levodopa and the conversion of all subjects to open‐label deprenyl made it possible to study the long‐term effect of early deprenyl and tocopherol treatment on the later development of levodopa‐associated side effects. The rate of developing these side effects did not differ among the original treatment groups (early versus late deprenyl and tocopherol versus nontocopherol). About 50% of subjects developed “wearing off,” 30% dyskinesias, and 25% “freezing” in each group. At the end of the study, the groups were similarly disabled on the Hoehn‐Yahr, Schwab‐England, and Unified Parkinsonapos;s Disease Rating scales and took similar amounts of levodopa. Young subjects were more likely to develop wearing off, women to develop dyskinesias, and older subjects with rapidly progressive disease to develop freezing. We conclude that prior treatment with deprenyl or tocopherol did not reduce the occurrence of subsequent levodopa‐associated adverse effects in this population.
Mental Illness Stigma and Causal Beliefs: Among Potential Mental Health Professionals

— Mental health professionals views about mental illness is an important issue which has not received enough attention. The negative stigma associated with mental illness can have many negative consequences. Unfortunately, health professionals working with the mentally ill can also exhibit stigma. It has been suggested that causal explanations or beliefs around the causes of mental illness may influence stigma. This study aims to gain a greater insight into stigma through examining stigma among potential mental health professionals. Firstly, results found that potential mental health professionals had relatively low social distance t (205) = -3.62, p <. 001. Secondly, an ANOVA indicated that the participants endorsed some causal beliefs more than others, F (1.82, 311.55) = 88.47, p < . 001, partial η 2 = . 34. Moreover, participants endorsed the biological causal explanation the most. Thirdly, results indicated that combined contact (quality and quantity) and causal beliefs (biological, psychological, and environmental) explained a significant proportion of the variance in stigma, R 2 = . 35, adjusted R 2 = . 33, F (5, 153) = 16.66, p < . 001. Quality of contact was the strongest predictor, with greater quality of contact associated with lower desired social distance. Also, quantity of contact, psychological and environmental causal explanations were also significant predictors of stigma. Greater quantity of contact and higher levels of environmental causal beliefs were associated with lower levels of stigma while psychological causal explanations were associated with higher levels of stigma. A series of multiple regression analyses were conducted that showed the three causal beliefs had different impacts on four factors of stigma (Authoritarian, Benevolence, Social restrictiveness, and Community mental health ideology). These analyses showed that psychological causal beliefs had the most positive impact. More research is required on this topic as it has important implications to the treatment and recovery for people suffering from mental illness. illness social
Fite-Faraco staining in combination with multiplex polymerase chain reaction: a new approach to leprosy diagnosis.

BACKGROUND Leprosy is not always an easy disease to diagnose, and patients can remain undiagnosed for longtime, not only at the peripheral clinics but also even at places with higher medical facilities, so, there is an urgent need for rapid and definitive modalities for leprosy diagnosis. This prospective study evaluates the ability of Fite-Faraco staining (FF staining) and multiplex polymerase chain reaction (PCR) over hematoxylin and eosin staining (H and E staining) and Ziehl-Neelsen staining (ZN staining). AIMS The aim of this perspective study is to evaluate the effectiveness of FF staining in combination with multiplex PCR for the early and rapid diagnosis of leprosy than any other coexisting diagnosis tool. METHODS Patients with new skin patches or nodules with or without evidence of nerve damage were selected for the study. Punch biopsy was collected according to standard procedures. Each biopsy sample was divided into two equal parts, one half was fixed in 4% (v/v) buffered neutral formalin and then accordingly embedded in paraffin. Sections were stained by three different methods: H and E staining for histopathological examination, ZN staining, and FF staining for detection of acid-fast bacilli (AFB). And the other part was subjected for DNA extraction and PCR was carried out by the obtained DNA sample. RESULTS H and E staining, ZN staining, FF staining, and PCR yield 58.2%, 50.9%, 60%, and 67.7% successful diagnosis of leprosy. The true diagnostic performances for these techniques were as follows: H and E staining - sensitivity 70.6%, positive predictive value (PPV) 81.9%, negative predictive value (NPV) 53.6%. For ZN staining - sensitivity 59.9%, PPV 69%, NPV 45.7%. For FF staining - sensitivity 74.6%, PPV 85.9%, NPV 56.7%, and for PCR - sensitivity 87.8%, PPV 95.6%, NPV 71.2%. CONCLUSION The combination of FF staining and PCR was shown to provide a rapid and definitive diagnosis in the majority of leprosy suspected cases with a higher positive likelihood ratio (+LR) of 7.76 and 2.716, respectively, than H and E staining of 2.244 and ZN staining of 1.378.
Financial assistance to state-owned enterprises by the state in South Africa : a case study of Eskom

State-owned enterprises (SOES) exist in South Africa to drive economic development and improve service delivery to the large population. In order for SOES to achieve their mandates, as set out by government through their shareholding department, financial assistance by the state is imperative. In the case of the monopolistic power utility, Eskom, the South African government (SAGO) has 100% ownership which is managed through the Department of Public Enterprises (DPE). This total ownership by the state means that government is responsible in ensuring that the utility is operational and supported financially. The current study was aimed at evaluating the financial assistance received by SOEs in South Africa by the state with specific focus on Eskom. Eskom was selected from the eight SOES managed by the DPE for the purpose of focusing the research. The focus of the study was on the financial assistance to SOES in South Africa by the state. In 2008, Eskom received funding from different sources through loan intervention of the South African government. The loan and guarantees made available to Eskom by government, enabled the SOE to achieve a positive credit rating. Data for this research was primarily collected through academic journals, books, Acts, White Papers, legislation and personal interviews at the National Treasury (NT). The recommendation that this research states relates to the need for a single policy document on state financial assistance to SOES in South Africa.
Regulation of Cofilin Activity by CaMKII and Calcineurin

Abstract:Cofilin promotes actin filament turnover by severing and depolymerizing actin filaments. Cofilin is inactivated by phosphorylation on Ser-3 by LIM-kinase1 (LIMK1) and is activated when protein phosphatase Slingshot-1L (SSH1L) dephosphorylates this residue. The authors have shown that Ca2+-induced cofilin dephosphorylation is mediated by calcineurin (Cn)-dependent activation of SSH1L. In this study, Ca2+/calmodulin-dependent protein kinase II (CaMKII) is shown to negatively regulate SSH1L activity and bind to SSH1L in a complex with 14-3-3. Phosphorylation of LIMK1 by CaMKII and its subsequent activation regulates the subcellular localization of SSH1L. Based on these findings, the authors suggest that CaMKII and Cn provide a switch-like mechanism that controls Ca2+-dependent LIMK1, SSH1L and cofilin activation, and subsequently actin cytoskeletal reorganization.
Psychotic disorders, eating habits, and physical activity: who is ready for lifestyle changes?

OBJECTIVES Significant weight gain is a serious side effect of many antipsychotic medications, yet successful strategies for significant weight loss are lacking. The transtheoretical model for weight management can be used to identify people who are ready to change (contemplation-preparation group) their eating habits and physical activity. This study compared characteristics of patients in Canada who had a psychotic disorder and were ready to make lifestyle changes with characteristics of patients who were not considering lifestyle changes. METHODS Participants were surveyed to determine their stages of change for eating habits and physical activity, and various characteristics were measured, including body mass index, body image, nutritional intake, and level of physical activity. RESULTS A total of 101 participants (64 men) (mean+/-SD age 35+/-11 years) were taking antipsychotic medications. Seventy-one percent had schizophrenia spectrum disorders, and 15% had affective psychosis. The prevalence of patients identified as being ready for change was higher than expected: 68% for eating habits and 54% for physical activity. Participants who were ready to change eating habits were also ready to change physical activity habits (p<.04). Stages of change for eating habits were associated with body mass index (p<.004), whereas stages of change for physical activity were associated with self-reported vigorous (p<.001) and moderate (p<.005) physical activity but not mild physical activity. CONCLUSIONS Clinicians may help patients develop healthier eating and physical activity habits by using the transtheoretical model, because it identifies patients who are ready to change to healthier lifestyle strategies and may help patients with antipsychotic-induced weight gain.
Real-time pose estimation on elevation maps for wheeled vehicles

Fast and accurate obstacle detection is a crucial component for autonomous robot navigation. It becomes even more important for a shared control vehicle like an electric wheeled walker, since the safety of the vehicle and the user depend on the correct classification of obstacles. This work describes a method for pose estimation of four-wheeled vehicles, which utilizes the fixed resolution of digital elevation maps to generate a detailed vehicle model. The vehicle's wheels are also approximated using digital elevation maps, allowing efficient calculation of wheel to ground contact points and therefore fast and accurate estimation of valid vehicle poses. To evaluate the proposed method, pose estimates are compared to three datasets including ground truth poses: one created using an external tracking system and two created by simulations of wheeled robots. It is also shown that the method is fast enough for real time operation.
Trachea–Innominate Artery Fistula: Retrospective Comparison of Treatment Methods

A fistula between the trachea and the innominate artery, a potentially fatal complication of tracheostomy, can be managed successfully. We have derived several guidelines from our experience with one such case and from a review of the 36 cases reported in the literature over the last decade. Diagnosis must be established before exsanguination occurs. Bronchoscopy and angiography are often nondiagnostic. Control of hemorrhage and a patent airway are the initial goals of treatment. Interruption of the innominate artery is the definitive treatment, with a low rebleeding rate (7%, 1/14 cases) and good long-term survival (64%, 9/14 cases). Maintenance of continuity of the innominate artery is contraindicated, because of a high rebleeding rate (60%, 6/10 cases) and poor long-term survival (10%, 1/10 cases). There is no convincing evidence that interruption of the innominate artery causes significant neurologic or vascular compromise.
An SVD-based approach for mitigating wall reflections in through-the-wall radar imaging

In this paper, we mitigate wall EM returns in through-the-wall radar imaging (TWRI) using singular value decomposition (SVD). To suppress wall reflections, the SVD is applied to the B-scan matrix of the received signals. The signal space is decomposed into three subspaces: the clutter subspace, the target subspace, and the noise subspace. Then, a set of normalized and smoothed eigen-components are combined to produce the target signal. Finally, delay-and-sum beamforming is applied to the reconstructed B-scan matrix to form the image. Experimental results demonstrate that the proposed method is effective in removing background, reducing clutter, and high-lighting the targets.
