Novel space vector PWM technology with lower common‐mode voltage for dual three‐phase PMSM

Pulse width modulation (PWM) converters generate switching common-mode voltages (CMV) across the load terminals. These voltages cause common mode currents, leading to bearing failure in motor loads and electromagnetic interference problems. This study proposes a novel space vector PWM strategy to reduce the CMV in the dual three-phase permanent magnet synchronous motor (PMSM) driven by two-level six-phase inverter. The novel space vector PWM algorithm discards the use of zero vectors. Firstly, the two largest voltage vectors of each sector are selected as main vectors to synthesise reference vector. Then, three groups voltage vector, which are opposite to the main vectors, have been selected as auxiliary vectors. Appropriate auxiliary vector selected is based on the length of zero voltage vector working time. Next, zero vector working time is distributed to the main and selected auxiliary vectors based on voltage-second principle. In addition, CMV and the harmonic component in z1z2 subspace of the proposed space vector PWM are analysed in detail. Finally, the expected CMV reduction to one-sixth of DC voltage and change rate of CMV in each cycle promised by the proposed novel space vector PWM are demonstrated with simulation and experimental results.
Counseling the husbands of postabortion patients in Egypt: Effects on husband involvement, patient recovery and contraceptive use

An ANE OR/TA Project qualitative study conducted in 1995 probed into women’s perceptions of abortion in Egypt, and the stress that postabortion patients experience during recovery. That study drew attention to the important role husbands can play in their wives’ recovery and subsequent use of contraception. This study was designed to test the effects of involving husbands in the postabortion medical-care process. Overall, the study indicates that providing counseling to husbands of postabortion patients is feasible, as the majority of husbands either accompanied their wife on admission or at discharge from the hospital. However, administrative changes are needed to enhance the effects of counseling and encourage greater husband involvement. Family planning services should be offered on the postabortion ward. Moreover, the physical setup at the ob/gyn ward may need to be changed to allow for the presence of husbands without causing inconvenience to other women. As this report states, counseling of husbands is acceptable to both postabortion patients and their husbands. With due consideration to procedures that ensure the patient’s right to privacy, counseling husbands of postabortion patients should be considered as an element of other postabortion-care services.
Assessment of fundamental movement patterns and risk of injury in male soccer players

Introduction. The aim of the study was to assess the functional status of male soccer players in different age groups who played on different surfaces. Methods. The study included 45 soccer players aged 13–35 years. Among them, 15 were junior players, 15 were players of the senior Silesia-Opole 3rd league (SL), and 15 were senior players in the futsal Extra Class league (SF). The functional status and basic motor skills were assessed according to the results obtained in seven motor tasks included in the Functional Movement Screen™ (FMS) test. Results. The mean total scores in the FMS test were statistically significantly higher among both senior futsal and senior 3 rd league players than among junior players. However, there were no significant differences between the results obtained by the two senior groups (SL and SF). Seniors achieved higher scores in most of the assessed tasks, but they performed significantly better than juniors only in the trunk rotary stability test. Juniors obtained correct results in the active straight leg raise trial significantly less frequently, but only in comparison with the SF group. Differences were also observed between the teams of seniors playing on different training surfaces (grass vs. hard floor). Conclusions. Senior players (those who played on grass as well as on hard floor) demonstrated a better functional status than juniors. Fewer deficits in fundamental movement patterns were identified in the SL group than in the SF group.
CPW FED FLEXIBLE GRAPHENE BASED THIN DUAL BAND ANTENNA FOR SMART WIRELESS DEVICES

A coplanar waveguide (CPW)-fed flexible dual-band antenna using graphene as conducting material and Kapton polyimide as a substrate is proposed. The antenna shows increased impedance bandwidth due to the use of CPW-feed having the values of 80.29% (1.64–3.84 GHz) and 6.31% (5.52– 5.88 GHz), respectively. The antenna has an overall size of 0. 38λ×0. 43λ at center frequency of 3.4 GHz. The proposed flexible antenna has gain values of 1.82 dBi and 1.68 dBi with efficiency values more than 86% which makes the antenna commercially viable for smart wireless products having space constraints.
FACTORS RELATED TO SELF-MANAGEMENT BEHAVIORS OF ELDERLY PATIENTS WITH COPD IN HAI PHONG, VIETNAM. ปัจจัยที่มีความสัมพันธ์กับพฤติกรรมการจัดการตนเองของผู้ป่วยผู้สูงอายุโรคปอดอุดกั้นเรื้อรังในเมืองไฮฟอง เวียดนาม

Abstract The purposes of this study were to describe self-management behaviors and its related factors including COPD knowledge, anxiety and social support of elderly patients with COPD. Simple random sampling was used to recruit the sample of 100 elderly patients with COPD at Viet-Tiep Friendship Hospital and Kien An General Hospital in Hai Phong, Vietnam. Five questionnaires were used to collect data during June to July 2015. Data were analyzed by using descriptive statistic, Pearson Product Moment Correlation Coefficient. The mean score of COPD self-management was at a moderate level (M = 2.72, SD = .42). The highest score was daily life management (M = 2.94, SD = .57) followed by self-efficacy (M = 2.85, SD = .65), symptom management (M = 2.78, SD = .58), emotion management (M = 2.49, SD = .65), and information management (M = 2.28, SD = .71) respectively. There were positive relationship between COPD self-management and COPD knowledge (r = .45, p .05). Finally, the findings of this study suggest that nursing intervention program in regarding of COPD knowledge and social support should be recommended for improving self-management behaviors of elderly patients with COPD.
BREAST CANCER AS A SECOND TUMOR AFTER RADIOTHERAPY IN PATIENT WITH HODGKIN’S LYMPHOMA-CASE REPORT AND LITERATURE REVIEW

Cancer induction after radiation therapy is known as a serious side effect. We present a female patient with breast cancer as a second malignancy after Hodgkin disease treatment, twelve years after the disease was detected. A Core Needle Biopsy was performed and a breast cancer was confirmed. The patient underwent neoadjuvant chemotherapy and preoperative radiotherapy to the right breast. After that, a radical right mastectomy was done, with a right axillary dissection. Subsequent histopathological examination revealed an invasive intraductal breast carcinoma. It is important to point out that there are potential risks and long-term complications of anticancer therapy among cancer survivors. Acta Medica Medianae 2017;56(1):71-74.
A Distributed Continuous-Time Algorithm for Nonsmooth Constrained Optimization

This article studies a distributed convex optimization problem with nonsmooth local objective functions subject to local inequality constraints and a coupled equality constraint. By combining the dual decomposition technique and subgradient flow method, a new distributed solution is developed in continuous time. Unlike the existing related continuous-time schemes either depending on specific initial conditions or on differentiability or strict (even strong) convexity of local cost functions, this study is free of initialization and takes into account general convex local objective functions which could be nonsmooth. Via nonsmooth analysis and set-valued LaSalle invariance principle, it is proved that a global optimal solution can be asymptotically obtained. Finally, the effectiveness of our algorithm is illustrated by numerical examples.
Degenerative Lumbale Instabilität – Definition, klinische und radiologische Zeichen, Management

Zusammenfassung Hintergrund Im klinischen Alltag von Wirbelsäulenchirurgen stellen Patienten mit Rücken- und oder Beinschmerzen aufgrund degenerativer LWS-Prozesse einen Großteil des zu behandelnden Patientenguts dar. Trotz der Häufigkeit dieses Erkrankungsbildes gestaltet sich die Diagnosestellung dennoch oft schwierig, da klinische Symptome und bildgebende Befunde meist unspezifisch sind. Somit stellt uns die Therapie dieser Volkskrankheit immer wieder vor große Herausforderungen, da das optimale Ziel, nämlich das Erreichen eines anhaltend guten oder zumindest zufriedenstellenden Therapieerfolgs häufig ausbleibt, unabhängig von der gewählten Therapieform. Wünschenswert wären prognostische Tests, die ein positives Ansprechen auf eine Therapieform (konservativ vs. operativ) voraussagen könnten. Eine der umstrittensten Erkrankungen aus dem degenerativen Formenkreis stellt die degenerative Instabilität und Mikroinstabilität dar. Auf die Frage, die uns als Wirbelsäulenchirurgen besonders interessiert, nämlich welche dieser Patienten von einer Operation, insbesondere einer spinalen Fusion, profitieren würden, gibt es leider immer noch keine klare Antwort. In diesem Übersichtsartikel werden die klinischen und radiologischen Untersuchungsmethoden und auch konservative und operative Therapieoptionen dargestellt unter Berücksichtigung der aktuellen Literatur. Methoden Literaturrecherche und Übersicht über das Thema degenerative Instabilität. Zusammenfassung Die degenerative Instabilität bleibt ein schwieriges und kontroverses Thema. Sichere klinische und radiologische Zeichen wie auch valide prognostische Tests, um ein positives Outcome nach spinaler Fusion vorherzusagen, fehlen bisher leider ebenso wie ein Behandlungsalgorithmus zur Therapie der sogenannten Mikroinstabilität. Bei der degenerativen Pseudolisthesis scheinen Patienten von einer stabilisierenden Operation im Vergleich zur alleinigen Dekompression hinsichtlich des Outcomes zu profitieren, hier werden eventuell die Langzeitergebnisse aus den 2016 im New England Journal of Medicine erschienenen RCTs Klarheit bringen.
Burnout and Coping Skills amongst Medical Officers: A study in a tertiary hospital in Malaysia

Burnout among doctors is hazardous, leading to stress which results in poor decision making and exposure to medical errors. This study aims to improve the knowledge gap of the issues of burnout and coping skills among medical officers. This study is a cross-sectional study involving 250 medical officers, using universal sampling. Of the total 250 participants, 63 (25.2%) were burnout. The presence of burnout was significantly associated with dysfunctional coping skills (t=-4.96; p <0.001). Burnout is prevalent among medical officers. It is vital to take actions that can promote good mental health in the form of coping skills and resilience training.Keywords: burnout; coping skills; doctors; medicaleISSN: 2398-4287 © 2019.

Bureaucracy and the balanced scorecard in health care settings.

PURPOSE We explore the relationship between the balanced scorecard (BSC) and neo-bureaucracy by investigating whether the operationalization of the BSC incorporates "neo-bureaucratic" ideas and whether the BSC implemented in a Portuguese Local Health Unit (LHU) demonstrates a neo-bureaucratic approach. DESIGN/METHODOLOGY/APPROACH We conduct semi-structured interviews with LHU staff and analyse documents to assess whether features of bureaucratic organization were evident in the use of a BSC by the LHU. FINDINGS We found nine bureaucratic features evident in the LHU's BSC. These were systematization, rationality, authority, jurisdiction, professional qualification, knowledge, discipline, transparency and accountability. The BSC used at the LHU demonstrated a neo-bureaucratic approach. ORIGINALITY/VALUE Our study helps to demystify bureaucracy and overcome prevailing prejudices regarding some of its principles. Health care managers should recognize and endorse neo-bureaucratic principles in developing a BSC. They should recognize the BSC as involving a neo-bureaucratic approach. The BSC is a valuable management tool that hospital managers should find useful in fostering flexibility, collaboration, innovation and adaptation - all of which should help lead to improved healthcare outcomes.
The Role of SOX-2 in the Diagnosis of Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is responsible for a large proportion of cancer deaths worldwide. HCC is frequently diagnosed after the development of clinical deterioration at which time survival is measured in months,. HCC diagnosis by biomarker SOX2 which contributes of tumorigenesis and metastasis. Properties of various types of cancers strongly supported the concept that SOX2 can be used as an effective marker for HCC diagnosis . Level of expression of SOX2 was assessed with a real-time reverse transcription-polymerase chain reaction approach in a set of samples for 20 patients including serum and tissue (tumor and non-tumor) samples and the level of ALB, AST and ALT were measured. Our work reported that Expression of SOX2 in serum of normal people was down regulated than patients serum and SOX2 expression in non tumor tissue was higher than HCC tissue . It is a novel and promising biomarker for HCC diagnosis Results Expression of SOX2 in tissue of normal people was higher than HCC patient on other hand Expression of SOX2 in serum of normal people was down regulated than HCC patients According to other study who examined the expression level of SOX2 in HCC tissues which has been indicated that SOX2 expression was down regulated in tissue of HCC patients and high expressed in serum of HCC patients Conclusion SOX2 is discovered to be a member of a family of gene regulator, and promising biomarker for HCC diagnosis.

Optimal hyperparameters for random forest to predict leakage current alarm on premises

While the number of private electrical facilities is increasing, there are not enough security personnel to perform the security work. In this paper, we propose a random forest model for predicting leakage current alarms in order to improve the efficiency of electrical safety operations. A random forest was created using periodic inspection data, alarm data, and meteorological data as explanatory variables, and generalization performance was evaluated by OOB-based F-measure. In order to obtain the highest performance, a grid search was performed to optimize the hyperparameters. As a result, it was possible to achieve alarm prediction with a certain level of performance. In addition, the optimal hyperparameters were found by grid search, and the F-measure was improved.
Dating in the time of “relational filter bubbles”: exploring imaginaries, perceptions and tactics of Italian dating app users

ABSTRACT In this paper, we address algorithmic imaginary, perception and tactics of Italian dating apps users. Little attention has hitherto been devoted to the ways in which the algorithms employed by mobile dating platforms (to rate users, to manage user visibility, to arrange results) might contrast, or enhance, people’s homophily. Our goal is to explore whether and how mobile dating algorithms modify the perception of what we define as “relational filter bubbles”; and whether, and how, users believe dating algorithms reshape (extend or limit) the heterogeneity of their intimate interactions. The paper builds on literature addressing online dating, the datafication of society, the rise of the so-called quantified self, and of the algorithmic culture. We organized 4 focus groups involving Italian dating apps users, who reported a variety of sexual orientations and of dating apps usage. Overall, while dating apps’ algorithms operate in an opaque way, participants developed an “algorithmic imaginary”. Moreover, they appreciate the role of mobile dating apps in reinforcing their relational homophily (their tendency to like people that are “similar” to them), whilst, at the same time, mainly using these apps for increasing the diversity of their intimate interactions in terms of extending their preexisting networks.
Systematic Reviews and Meta-analysis in Evidence-based Orthodontics: An Appraisal and Methodology

Orthodontics is not only an art but also a science, and the key to practicing it likewise lies with implementing evidence-based orthodontics (EBO). Systematic reviews (SRs) and Meta-analyses (MAs) are considered to be the “gold standard” or highest level of evidence in EBO. The limitations of traditional, narrative reviews have led to the increased popularity of SRs due to their objective and transparent methodology, which makes the evidence generated by them more reliable and unbiased. With SRs and MAs becoming the mainstay of Orthodontic research and EBO, it is imperative to be in the know of the technicalities of these tools of research synthesis. The present paper provides an overview of the SR methodology and describes in detail the key steps in conducting SRs or MAs viz., formulating the review question, defining the criteria for inclusion of studies, identifying all relevant studies by a meticulous search process, including studies which meet pre-defined criteria, assessing quality of included studies and finally analysing and interpreting the collective findings from included individual studies. The paper can thus be used as a guide for the whats, whens, whys and hows of carrying out a systematic review and meta-analysis, and generate the highest quality of evidence available for delivering the best patient care.
FACTORS ASSOCIATED WITH LOSS TO FOLLOW UP OF ADULT PATIENTS LIVING WITH HIV IN KIAMBU COUNTY AND REFERRAL HOSPITAL, KIAMBU COUNTY, KENYA

Purpose: The main objective of this study was to determine the factors associated with loss to follow up and its effects on treatment adherence among HIV positive patients in Comprehensive Care Clinic in Kiambu County Referral Hospital, Kiambu County.Methodology: This was a descriptive cross sectional study conducted in Kiambu County referral hospital. HIV positive adult patients enrolled in care and documented to have been lost to follow up according to case definition were recruited as participants. A list was generated from the facility’s database to calculate a sample size of 327. Random sampling was used to get patients who met the inclusion criteria. Structured questionnaires administered to participants were used and resultant data was coded, cleaned, sorted and analyzed using Statistical Package for Social Sciences version 17. Participants were called on phone to the hospital Comprehensive care clinic and those not reachable on phone residing within the catchment area were visited in their homes. Results: The study found that a third all patients could not be traced by the phone call to the patients or to the treatment supporter or by physical home visit and could therefore their true status was not identified. A proportion of 12.9% classified as lost to follow up were actually dead while 4.3% of files of patient classified as lost were not physically found in the hospital records. Those who were confirmed alive were 69.6% from whom 25.5% had discontinued with care, 41.6% had transferred out and 32.9 % had self- transferred to other facilities where they were continuing with care. The rate of LFTU was found to be 16% against a target of a 10% maximum rate. There is the need to strengthen mechanisms to capture details on deaths as they occur, improve linkage to other facilities, improve on documentation of all patient data including contact and transfer details.
Simple and efficient measurement of transcription initiation and transcript levels with STRIPE-seq

Accurate mapping of transcription start sites (TSSs) is key for understanding transcriptional regulation. However, current protocols for genome-wide TSS profiling are laborious and/or expensive. We present Survey of TRanscription Initiation at Promoter Elements with high-throughput sequencing (STRIPE-seq), a simple, rapid, and cost-effective protocol for sequencing capped RNA 5’ ends from as little as 50 ng total RNA. Including depletion of uncapped RNA and SPRI bead cleanups, a STRIPE-seq library can be constructed in about five hours. We demonstrate application of STRIPE-seq to TSS profiling in yeast and human cells and show that it can also be effectively used for measuring transcript levels and differential gene expression analysis. In conjunction with our ready-to-use computational analysis workflows, STRIPE-seq is a straightforward, efficient means by which to probe the landscape of transcriptional initiation.
