Speed Control of Matrix Converter-Fed Five-Phase Permanent Magnet Synchronous Motors under Unbalanced Voltages

Five-phase permanent magnet synchronous motors (PMSM) have special applications in which highly accurate speed and torque control of the motor are a strong requirement. Direct Torque Control (DTC) is a suitable method for the driver structure of these motors. If in this method, instead of using a common five-phase voltage source inverter, a three-phase to five-phase matrix converter is used, the low-frequency current harmonics and the high torque ripple are limited, and an improved input power factor is obtained. Because the input voltages of such converters are directly supplied by input three-phase supply voltages, an imbalance in the voltages will cause problems such as unbalanced stator currents and electromagnetic torque fluctuations. In this paper, a new method is introduced to remove speed and torque oscillator factors. For this purpose, motor torque equations were developed and the oscillation components created by the unbalanced source voltage, determined. Then, using the active and reactive power reference generator, the controller power reference was adjusted in such a way that the electromagnetic torque of the motor did not change. By this means, a number of features including speed, torque, and flux of the motor were improved in terms of the above-mentioned conditions. Simulations were analyzed using Matlab/Simulink software.
ETHIONAMIDE AND ISONIAZID IN PREVIOUSLY UNTREATED CASES OF PULMONARY TUBERCULOSIS.

SUMMARY Patients with newly diagnosed pulmonary tuberculosis were treated with a combination of ethionamide 1 gm. daily and isoniazid 400 mg. daily. Twenty-six patients were observed for at least six months and eight for at least one year. Clinical, radiologic, and bacteriologic progress was satisfactory in all these cases. Conversion of sputum was achieved in every case, and there was no evidence of emergence of bacterial resistance to either drug. The incidence of ethionamide toxicity which occurred, however, indicates that a daily dose of 1 gm. of the drug is too high for routine use. Side effects observed were nausea, jaundice, mental disturbance, and peripheral neuritis. The excellent results in patients who could tolerate the ethionamide-isoniazid therapy warrant further trial of this drug combination, since the use of a lower dosage level of ethionamide may make it acceptable in regard to toxicity without sacrificing its therapeutic effectiveness.
BAX and PKCα Modulate the Prognostic Impact of BCL2 Expression in Acute Myelogenous Leukemia

Previously, we demonstrated that the level of BCL2 expression is prognostic in acute myelogenous leukemia (AML). High levels of BCL2 correlate with an adverse outcome when associated with favorable and intermediate prognosis cytogenetics (FIPC), whereas low levels portend an adverse outcome when associated with unfavorable cytogenetics (UC). Because BCL2 function can be modulated by dimerization with family members, like BAX, or by phosphorylation by protein kinase C α (PKCα), we hypothesize that the relative expression of these proteins in primary leukemic cells might alter the prognostic impact of BCL2 expression. We therefore measured BAX and PKCα protein levels in peripheral blood mononuclear cell lysates from 165 newly diagnosed AML patients and correlated the expression of these proteins with BCL2 expression, patient survival, and remission induction success. Expression levels of BAX and PKCα were normalized against a control cell line, K562. BAX and PKCα expression levels were heterogeneous and did not correlate with the percentage of blasts in the sample ( R 2 = 0.01 and <0.01). The median expression of both was similar across FAB groups but the range was greater for M4. A similar distribution of expression was observed in all cytogenetic groups, except that patients with inversion 16 demonstrated lower levels of BAX. Individually, neither PKCα nor BAX expression was prognostic of response to induction therapy or survival. A similar outcome was obtained when patients were stratified by cytogenetics into FIPC and UC groups. However, the ratio of either BCL2:BAX (B2:BX) or PKCα*B2:BX (PK*B2:BX) was highly prognostic. Patients with FIPC and a lower ratio (less than median) of either B2:BX or PK*B2:BX had a significantly higher remission induction rate (88 versus 69%, P = 0.04) and longer survival (median: 141 versus 80.5 weeks, P = 0.007) compared with those with ratios more than median. For patients with UC, values of either B2:BX or PK*B2:BX below the median had an inferior response rate to induction therapy (35 versus 78%, P = 0.0006) and inferior survival outcomes (median survival: 11 versus 53 weeks, P = 0.00002). Interestingly, FIPC and UC patients with antiapoptotic ratios (defined as B2:BX or PK*B2:BX more than median) had identical response rates and survival outcomes. In multivariate analyses, the compound variables of cytogenetics and B2:BX, or PK*B2:BX were independent predictors of survival. These results suggest that expression levels of proteins that affect the functional status of BCL2 modify the prognostic impact of BCL2 and suggest that the role of apoptosis in different cases of AML varies independently in the different cytogenetic subgroups.
Contextual Exemplar Classifier-Based Image Representation for Classification

The use of local features for image representation has become popular in recent years. Local features are often used in the bag-of-visual-words scheme. Although proven effective, this method still has two drawbacks. First, local regions from which local features are extracted are not discriminative enough for visual tasks. Hence, the combination of local features is necessary. Second, the semantic gap between visual features and human perception also hinders the performance. To address these two problems, in this paper, we propose a novel contextual exemplar classifier-based method for image representation and apply it for classification tasks. Each exemplar classifier is trained to separate one training image from the other images of different classes. We partition each image into a number of regions and use the responses of these exemplar classifiers as the image region’s representation. The contextual relationship is then modeled using mixture Dirichlet distributions. A bilayer model is used to predict image classes with $L_{2}$ constraints. Experimental results on the Natural Scene, Caltech-101/256, Flower-17/102, and SUN-397 data sets show that the proposed method is able to outperform the state-of-the-art local feature-based methods for image classification.

Uncertainty in the Relation between Exposure to Magnetic Fields and Brain Cancer due to Assessment and Assignment of Exposure and Analytical Methods in Dose‐Response Modeling

Abstract: Incomplete scientific knowledge ensures that, in every study, uncertainty will enter the processes of exposure estimation and exposure‐response modeling. In the light of the heated debate about the health effects of magnetic fields resulting from power production and usage, we undertook a sensitivity analysis to evaluate uncertainty related to key decisions in a previous study of brain cancer and occupational exposure to magnetic fields. The findings appeared to be relatively insensitive to most variations in the methods of exposure assessment, exposure assignment, and data analysis. The results can be visualized by defining bands of uncertainty about a best‐bet estimate of the association based on our original study. These bands of methodological uncertainties were similar in magnitude to the conventional 95% confidence interval, but they rovide a measure of the potential range of systematic bias in the results, rather than reflecting statistical variability alone. The methodology employed here can be applied to other studies, and other researchers are encouraged to conduct sensitivity analysis in order to estimate methodological uncertainty as an alternative to statistical confidence intervals.
Psychometric properties of the Liebowitz Social Anxiety Scale

Background. The present study provides data on the reliability, validity and treatment sensitivity of the Liebowitz Social Anxiety Scale (LSAS), one of the most commonly used clinician-administered scales for the assessment of social phobia. Method. Three hundred and eighty-two patients from several studies of the treatment of social phobia were evaluated. An independent assessor administered the LSAS to each patient prior to the initiation of treatment. Patients also completed other measures of social anxiety and avoidance, although the specific measures varied across samples. Results. The LSAS and its subscales were normally distributed and demonstrated excellent internal consistency. The convergent validity of the LSAS was demonstrated via significant correlations with other commonly-used measures of social anxiety and avoidance. These correlations also tended to be larger than correlations with measures of depression, especially after treatment. However, the pattern of correlations of LSAS subscales with one another and with the other measures suggest that the fear subscales and the avoidance subscales may not be sufficiently distinct in clinical samples. The LSAS was also demonstrated to be sensitive to the effects of pharmacological treatments of social phobia over time and in comparison to double-blind pill placebo. Conclusion. The LSAS appears to be a reliable, valid and treatment sensitive measure of social phobia. Further study of the LSAS, both in samples with severe social phobia and in community samples, is needed.
Selection and application of Streptococcus bovis as a silage inoculant

Three strains of Streptococcus bovis, a homolactic bacterium capable of utilizing starch, were evaluated for growth kinetics and ability to decrease the pH of alfalfa silage. A selected strain was evaluated for its competitiveness as an inoculant with Enterococcus faecium, an organism used in inoculants, and for its ability to enhance the effect of a commercial inoculant. Testing was completed over three studies using wilted alfalfa (28 to 34% dry matter) ensiled into laboratory silos. Treatments were control, E. faecium, E. faecium and commercial inoculant, S. bovis, and S. bovis and commercial inoculant. Replicate silos were emptied and analyzed at 0.5, 1, 2, 4, 8, and 40 days for pH, fermentation products, and nitrogen fractions. S. bovis alone lowered the pH quicker and improved silage parameters early in the fermentation compared with E. faecium, the commercial inoculant, and control treatments. When combined with a commercial inoculant, S. bovis lowered pH more quickly than the commercial inoculant alone and E. faecium plus commercial inoculant. At 40 days, S. bovis combination had lower pH and ammonia nitrogen and acetate contents than the E. faecium combination. Starch in the silage was not utilized by S. bovis as had been anticipated. Results indicate that S. bovis was more effective than E. faecium as a silage inoculant and could enhance a commercial inoculant on low-dry-matter alfalfa.
Analytical Model of the Parasitic Bipolar Junction Transistor in Low-Doped Double-Gate FinFETs for Pass-Gate Circuits

The transient parasitic bipolar effect in floating-body double-gate FinFETs with low-doped bodies is analytically modeled. The obtained analytical transient bipolar current and charge models have predictive power for various device structures. These models are applicable when the majority carrier concentration in accumulation conditions noticeably exceeds the body doping concentration. The physical insights obtained from the developed current model are used to analyze the transient bipolar current IBJT(t) for different device structures. It is shown that the gate-body-source capacitive coupling is an important parameter in IBJT(t) control.
Use of Platelet-Rich Plasma With Split-Thickness Skin Grafts in the High-Risk Patient

Split-thickness skin grafting (STSG) is commonly employed for soft-tissue coverage because of its broad application for use, ease of harvest, and universal equipment. STSG healing proceeds through 3 stages: (1) anchorage, (2) inosculation, and (3) maturation. The success of the first 2 stages is critical to the overall success. Bolster dressings of various types are universally applied to create apposition of the skin graft with the granular bed, thereby preventing shearing forces and fluid accumulation until vascular ingrowth can occur. The application of autologous platelet-rich plasma (PRP) to STSG application sites has been recently described and theorized to provide immediate skin graft anchorage as well as inosculation of the STSG with nutrient-rich blood media. This study was performed to report the time to ≥90% primary healing of STSGs augmented with application of PRP in a high-risk patient population. The mean time to ≥90% STSG recipient site healing was 16 ± 4.2 days, as determined by retrospective chart review and digital photograph analysis. The addition of PRP to STSG recipient sites seems to enhance primary healing and reduce healing time, likely as a result of shearing force reduction and enhancement of the wound environment with growth factors.
Circularly polarized RFID tag for metal surface mount

A passive UHF band RFID tag antenna design is presented here. To allow circular polarization (CP) radiation, compact size, and metal surface mount characteristics, the radiating square patch is loaded with two pairs of unequal slits, while a quarter-wavelength microstrip line connected to a tag-chip and terminated by a short-circuited stub is used to excite the radiating patch. The 10 dB impedance bandwidth of the tag antenna is measured to be 31 MHz (896-927 MHz), while its 3 dB CP bandwidth is 6 MHz (911-917 MHz). Further experiment has demonstrated that the proposed tag antenna can provide better reading distance when mounted on a metallic surface as compared with the free-space condition.
Imaging the Folate Receptor on Cancer Cells with 99mTc-Etarfolatide: Properties, Clinical Use, and Future Potential of Folate Receptor Imaging

Folate receptor (FR) can be used as a therapeutic target because of its expression on different epithelial cancers, such as ovarian, non–small cell lung, endometrial, and breast cancer. Assessing FR expression in tumors may help to identify patients who can benefit from FR-targeted therapeutics, such as vintafolide and farletuzumab. Different methods exist to detect FR expression. Tissue sampling has limited clinical utility, mainly because it requires an invasive procedure. 99mTc-etarfolatide, a 99mTc-labeled folate conjugate, is in late-phase trials in Europe and the United States. It allows noninvasive, whole-body imaging of the FR. This review focuses on this FR-imaging agent and how it may be used to direct FR-targeted therapy.
Analysis and Design of Generalized BICM-T System

The performance of bit-interleaved coded modulation (BICM) using convolutional codes in nonfading channels can be significantly improved if the coded bits are not interleaved at all. This particular BICM system is referred to as BICM trivial (BICM-T). In this paper, we analyze a generalized BICM-T system that uses a nonequally spaced signal constellation in conjunction with a bit-level multiplexer in an additive white Gaussian noise (AWGN) channel. As such, one can exploit the full benefit of BICM-T by jointly optimizing different system modules to further improve its performance. We also investigate the performance of the considered BICM-T system in the Gaussian mixture noise (GMN) channel because of its practical importance. The presented numerical results show that an optimized BICM-T system can offer gains up to 1.5 dB over a non-optimized BICM-T system in the AWGN channel for a target bit error rate of 10-6. The presented results for the GMN channel interestingly reveal that if the strength of the impulsive noise component, i.e., the noise component due to some ambient phenomenon in the GMN, is below a certain threshold level, then the BICM-T system performs significantly better as compared to traditional BICM system.
Pioglitazone compared with metformin increases pericardial fat volume in patients with type 2 diabetes mellitus.

CONTEXT Peroxisome proliferator-activated receptor-gamma agonists are involved in fat cell differentiation. OBJECTIVE The objective of the study was to investigate the effect of pioglitazone vs. metformin on pericardial fat volume in type 2 diabetic (T2DM) patients. Furthermore, we aimed to assess the relationship between pericardial fat volume, other fat compartments, and myocardial function at baseline and after treatment. DESIGN This was a prospective, randomized, double-blind, intervention study. SETTING The study was conducted at a university hospital. PATIENTS Patients included 78 men with T2DM (aged 56.5 +/- 0.6 yr; glycosylated hemoglobin 7.1 +/- 0.1%) without structural heart disease. INTERVENTION Patients were randomly assigned to pioglitazone (30 mg/d) or metformin (2000 mg/d) and matching placebo during 24 wk. MAIN OUTCOME MEASURES Pericardial and abdominal fat volumes and myocardial left ventricular function were measured by magnetic resonance imaging and hepatic and myocardial triglyceride content by proton magnetic resonance spectroscopy. RESULTS Pioglitazone increased pericardial fat volume [30.5 +/- 1.7 ml (baseline) vs. 33.1 +/- 1.8 ml], whereas metformin did not affect pericardial fat volume (29.2 +/- 1.5 ml vs. 29.6 +/- 1.6 ml, between groups P = 0.02). After correction for body mass index and age, only visceral fat volume correlated with pericardial fat volume at baseline (r = 0.55, P < 0.001). The increase in pericardial fat volume induced by pioglitazone was not associated with a decrease in left ventricular diastolic function. CONCLUSION In T2DM patients, pioglitazone increases pericardial fat volume. This increase in pericardial fat volume did not negatively affect myocardial function after 24 wk. These observations question the notion of an inverse causal relationship between pericardial fat volume and myocardial function.
Improving Wireless Sensor Networks Life Time Using Neural Network

The use of wireless sensor networks (WSNs) has grown very fast in the last decade. The main concern in wireless Sensor Network is how to keep the network working in spite of sensors limited energy resource case the performance of that Network depends on their lifetime. Maximizing network lifetime in Wireless Sensor Networks (WSNs) was done by controlling total energy consumed along the network and trying to minimize it. To support high scalability and better data aggregation, sensor nodes are often grouped into disjoint, non overlapping subsets called clusters. Today Cluster based routing protocol are well known approach for extending Wireless Sensor Networks. In this work we merge the idea of cluster with neural network and measure the effect of changing the number of cluster on the number of live node and reserved energy. Experimental results end up with the proposed methodology gives lifetime than old ones, such as (LEACH, and LEA2C). While it can ensure more network coverage in it's lifetime through distributed death of nodes in network space.
Mindful Attention Increases and Mediates Psychological Outcomes Following Mantram Repetition Practice in Veterans With Posttraumatic Stress Disorder

Background:Several evidence-based treatments are available to veterans diagnosed with posttraumatic stress disorder (PTSD). However, not all veterans benefit from these treatments or prefer to engage in them. Objectives:The current study explored whether (1) a mantram repetition program (MRP) increased mindful attention among veterans with PTSD, (2) mindful attention mediated reduced PTSD symptom severity and enhanced psychological well-being, and (3) improvement in mindful attention was due to the frequency of mantram repetition practice. Research Design:Data from a randomized controlled trial comparing MRP plus treatment as usual (MRP+TAU) or TAU were analyzed using hierarchical linear models. Subjects:A total of 146 veterans with PTSD from military-related trauma were recruited from a Veterans Affairs outpatient PTSD clinic (71 MRP+TAU; 75 TAU). Measures:The Clinician Administered PTSD Scale (CAPS), PTSD Checklist (PCL), the Brief Symptom Inventory-18 depression subscale, Health Survey SF-12v2, and Mindfulness Attention Awareness Scale (MAAS) were used. Frequency of mantram repetition practice was measured using wrist-worn counters and daily logs. Results:Intent-to-treat analyses indicated greater increases in mindful attention, as measured by the MAAS, for MRP+TAU as compared with TAU participants (P<0.01). Mindful attention gains mediated previously reported treatment effects on reduced PTSD symptoms (using both CAPS and PCL), reduced depression, and improved psychological well-being. Frequency of mantram repetition practice in turn mediated increased mindful attention. Conclusions:The MRP intervention and specifically, mantram practice, improved mindful attention in veterans with PTSD, yielding improved overall psychological well-being. MRP may be a beneficial adjunct to usual care in veterans with PTSD.

This paper presents a high drivability of full adder with less area and power consumption. This GDI based full adder is implemented by using both gate diffusion input (GDI) technique and pass transistor logic that leads to be a reduced area and power. To reducing the static power, ultralow power diode (ULPD) is used. The leakage current of this diode lies within the range of pA. The comparison has been done between existing systems like CMOS, CPL and hybrid full adders with proposed full adder. All full adders are designed with gpdk 0.18 um in Cadence Virtuoso schematic, and simulations are done in a Spectre Simulator.

The hDLG‐associated protein DAP interacts with dynein light chain and neuronal nitric oxide synthase

Postsynaptic density (PSD)‐95 interacts with and mediates clustering of the N‐methyl‐ d‐aspartate‐receptors (NMDA‐R). PSD‐95 also interacts with the hDLG‐associated protein DAP, which is also called Synapse‐associated protein 90‐associated protein (SAPAP), and Guanylate kinase‐associated protein (GKAP).
