Extended S-Parameter Method Including Radiation Pattern Measurements of an Antenna

Coaxial cables connected to the antenna frequently affect the characteristics of the antenna. Although the S-parameter method is one of the most effective methods of reducing the influence of the coaxial cables, it has so far only been applied to impedance measurements. We propose an extended S-parameter method that can also be applied to radiation pattern measurements of amplitude and phase. In this method, two cables are connected to an antenna, and the excitation coefficients of the two cables are obtained from the S-parameters under the condition where the unbalanced current of the coaxial cables is reduced. From array patterns generated with these excitation coefficients, we can obtain the radiation patterns with a reduced unbalanced current of the coaxial cables. We apply this method to dipole antennas and a helical antenna on a small housing. Our simulated and measured results demonstrate the validity of the proposed method and 20 dB reduction of the influence of the coaxial cables.
Police Officer Gender and Attitudes toward Intimate Partner Violence: How Policy Can Eliminate Stereotypes

This article reviews the existing literature on differences in police response to IPV (intimate partner violence) based on officer gender and suggests policy changes that could address common issues identified in the research. Authors reviewed research on the effect of police officer gender on arrest rates of abusers, the criteria officers consider when making the arrest decision, and whether officers and IPV victims have a gender preference for the officers sent to IPV calls. Due to a lack of existing research, it is unclear if officer gender has a significant effect on arrest rates in IPV cases. However, gender is related to officers' beliefs, stereotypes and reactions to IPV. There is evidence that a masculine police culture affects men officers' belief in negative stereotypes regarding women officers. These gender differences are rooted in widely held beliefs in traditional gender roles and in the masculine police culture that contends that IPV is not a serious crime. Based on a review of scholarly studies and existing policies, we propose interventions to improve both the police response to IPV and the elimination of the masculine police culture, including, but not limited to expansion of (and adherence to) mandatory arrest, sensitivity training to the effects of police response on IPV victims, and improved techniques of recruiting men officers. This is the first policy-oriented article to thoroughly examine research on whether officer gender affects police response to IPV.
Tracing cells throughout development

In the article “Predetermined embryonic glial cells form the distinct glial sheaths of the Drosophila peripheral nervous system” we combined our expertise to identify glial cells of the embryonic peripheral nervous system on a single cell resolution with the possibility to genetically label cells using Flybow. We show that all 12 embryonic peripheral glial cells (ePG) per abdominal hemisegment persist into larval (and even adult) stages and differentially contribute to the three distinct glial layers surrounding peripheral nerves. Repetitive labelings of the same cell further revealed that layer affiliation, morphological expansion, and control of proliferation are predetermined and subject to an intrinsic differentiation program. Interestingly, wrapping and subperineurial glia undergo enormous hypertrophy in response to larval growth and elongation of peripheral nerves, while perineurial glia respond to the same environmental changes with hyperplasia. Increase in cell number from embryo (12 cells per hemisegment) to third instar (up to 50 cells per hemisegment) is the result of proliferation of a single ePG that serves as transient progenitor and only contributes to the outermost perineurial glial layer.
From Early Intervention to Preschool: Preparing Parents for the Transition.

This practicum addressed the anxiety and stress experienced by parents when their 3-year-old child with a disability or risk of developmental delay is transitioning from early intervention services to preschool. Questionnaires were administered to 20 parents to identify the causes of stress and anxiety during transitions and to determine their knowledge, involvement, and satisfaction with the transition. In addition, five staff members of the public schools were interviewed regarding preparation of parents for the transition. Factors which were found to contribute to parents' stress and anxiety concerned lack of parent involvement and information regarding the new program, the closed door policy of the new placement, and the lack of both a written transition plan and Lnteragency collaboration. In response, four parent education workshops and a familiarization visit to the preschool programs were conducted. The workshops, which included both the sending and receiving teachers, addressed transitions, placement options, rights of parents of special needs children, and parent participation. The strategy was successful in reducing stress and anxiety levels of parents and increasing their knowledge of and confidence in the transition process. Appendices provide the pre/post-tests, interview form, and a workshop evaluation. (Contains 43 references.)

InverseFaceNet: Deep Monocular Inverse Face Rendering

We introduce InverseFaceNet, a deep convolutional inverse rendering framework for faces that jointly estimates facial pose, shape, expression, reflectance and illumination from a single input image. By estimating all parameters from just a single image, advanced editing possibilities on a single face image, such as appearance editing and relighting, become feasible in real time. Most previous learning-based face reconstruction approaches do not jointly recover all dimensions, or are severely limited in terms of visual quality. In contrast, we propose to recover high-quality facial pose, shape, expression, reflectance and illumination using a deep neural network that is trained using a large, synthetically created training corpus. Our approach builds on a novel loss function that measures model-space similarity directly in parameter space and significantly improves reconstruction accuracy. We further propose a self-supervised bootstrapping process in the network training loop, which iteratively updates the synthetic training corpus to better reflect the distribution of real-world imagery. We demonstrate that this strategy outperforms completely synthetically trained networks. Finally, we show high-quality reconstructions and compare our approach to several state-of-the-art approaches.
microRNA and Cancer

MicroRNAs (miRNAs), a class of small, regulatory, non-coding RNA molecules, display aberrant expression patterns and functional abnormalities in human diseases including cancers. This review summarizes the abnormally expressed miRNAs in various types of human cancers, possible mechanisms underlying such abnormalities, and miRNA-modulated molecular pathways critical for cancer development. Practical implications of miRNAs as biomarkers, novel drug targets and therapeutic tools for diagnosis, prognosis, and treatments of human cancers are also discussed.
2D sound-source localization on the binaural manifold

The problem of 2D sound-source localization based on a robotic binaural setup and audio-motor learning is addressed. We first introduce a methodology to experimentally verify the existence of a locally-linear bijective mapping between sound-source positions and high-dimensional interaural data, using manifold learning. Based on this local linearity assumption, we propose an novel method, namely probabilistic piecewise affine regression, that learns the localization-to-interaural mapping and its inverse. We show that our method outperforms two state-of-the art mapping methods, and allows to achieve accurate 2D localization of natural sounds from real world binaural recordings.
Pseudomonas aeruginosa PA1006, Which Plays a Role in Molybdenum Homeostasis, Is Required for Nitrate Utilization, Biofilm Formation, and Virulence

Pseudomonas aeruginosa (Pae) is a clinically important opportunistic pathogen. Herein, we demonstrate that the PA1006 protein is critical for all nitrate reductase activities, growth as a biofilm in a continuous flow system, as well as virulence in mouse burn and rat lung model systems. Microarray analysis revealed that ΔPA1006 cells displayed extensive alterations in gene expression including nitrate-responsive, quorum sensing (including PQS production), and iron-regulated genes, as well as molybdenum cofactor and Fe-S cluster biosynthesis factors, members of the TCA cycle, and Type VI Secretion System components. Phenotype Microarray™ profiles of ΔPA1006 aerobic cultures using Biolog plates also revealed a reduced ability to utilize a number of TCA cycle intermediates as well as a failure to utilize xanthine as a sole source of nitrogen. As a whole, these data indicate that the loss of PA1006 confers extensive changes in Pae metabolism. Based upon homology of PA1006 to the E. coli YhhP protein and data from the accompanying study, loss of PA1006 persulfuration and/or molybdenum homeostasis are likely the cause of extensive metabolic alterations that impact biofilm development and virulence in the ΔPA1006 mutant.
Predictors of Sense of Belonging for Students with Psychological Conditions

Title of dissertation: PREDICTORS OF SENSE OF BELONGING FOR STUDENTS WITH PSYCHOLOGICAL CONDITIONS Michele Matteo Mackie, Doctor of Philosophy, 2013 Dissertation directed by: Dr. William Strein Professor Department of Counseling, Higher Education, and Special Education The purpose of this study was to develop a portrait of students with psychological conditions, to determine the predictors of sense of belonging for these students, and to draw comparisons between the collegiate experiences of students with, and those without, psychological conditions. Using data from the 2009 Multi-Institutional Study of Leadership, a sample of students who self-reported having a psychological condition and a randomly selected comparative sample of students without psychological conditions were drawn. Descriptive statistics were used to develop a portrait of students with psychological conditions relative to gender, class standing, academic performance, and co-curricular student involvement. Chi-square tests for independence and independent groups t-tests were used to make comparisons between students with psychological conditions and those who did not report having a psychological condition. Using a hierarchical multiple regression, framed in Astin’s (1993) I-E-O model, predictors of sense of belonging were identified for students with psychological conditions and the comparative sample. Equality of beta coefficient testing was conducted to determine if the variables that predict sense of belonging for students who self-reported a psychological condition differed significantly from the predictors of sense of belonging for the comparative sample. Results indicated that the distribution of students with psychological conditions differed significantly across categories related to gender, class standing, college GPA, and involvement in specific types of co-curricular activities. Additionally, students who self-reported a psychological condition reported lower perceptions of sense of belonging compared to those who did not. The regression analyses and equality of beta coefficient testing revealed that there are no significant differences between the variables that predict sense of belonging for students with psychological conditions and the comparative sample. Implications for practice and directions for future research emphasize the need for better understanding the issue of college student mental health and developing interventions that can be applied in and outside of the classroom to assist students with psychological conditions in collegiate success.

Protein v. enzymic protein hydrolysates. Nitrogen utilization in starved rats

The present study was carried out to compare the effects of four isoenergetic and isonitrogenous diets on the N utilization, total serum protein concentration and serum amino acid profile in starved rats at weaning. These diets differed only in the molecular form of two milk proteins (whey protein and casein), which were either native or partly hydrolysed. Male Wistar rats at weaning were fasted for 3 d and then refed with one of the four diets for 48 h. No differences were observed in the body weight gain, protein digestibility and total serum protein concentration between groups after the refeeding period and all the N balances were positive. N retention was higher in the two groups of rats given the protein-hydrolysate-based diets compared with those given the intact-protein-based diets. This was associated with a lower urinary N excretion in rats, given the whey-protein-hydrolysate and the casein-hydrolysate diets. Despite this fact, the serum amino acid pattern of rats given the hydrolysed protein diet was very similar to that of those given the corresponding native protein diet. In conclusion, we have proved that enzymic hydrolysates from milk proteins have equivalent effects to native proteins in recovery after starvation in rats at weaning, on N absorption, total serum protein concentration and serum amino acid profile, and even give a higher N retention. We did not observe any harmful effect in using protein hydrolysates instead of native proteins.
Impact of process parameter and supply voltage fluctuations on multi-threshold-voltage seven-transistor static memory cells

Conventional Static Random Access Memory (SRAM) cells suffer from an intrinsic data instability problem due to directly-accessed data storage nodes during a read operation. Noise margins of memory cells further shrink with increasing variability and decreasing supply voltage in scaled CMOS technologies. A selected set of novel seven-transistor (7T) and conventional six-transistor (6T) multi-threshold-voltage memory circuits are characterized for data stability, write margin, and idle mode leakage currents with an equal area constraint under parameter variations in this paper. The mean of the statistical read static noise margin distribution is enhanced by up to 2.4X and the mean of the statistical array leakage power consumption distribution is reduced by up to 82% with the triple-threshold-voltage 7T SRAM cells as compared to the traditional 6T SRAM cells in a UMC 80nm CMOS technology.
The Diagnosis and Treatment of Pouchitis in Inflammatory Bowel Disease

The ileal pouch anal anastomosis (IPAA) procedure has become the preferred surgical option for most patients with ulcerative colitis who require surgical removal of the colorectum. The vast majority of patients with this new anatomy will either not develop pouchitis or develop a few discrete episodes of acute pouchitis. However approximately one fourth of patients will develop recurrent pouchitis, with 5% being categorized as chronic pouchitis requiring maintenance therapy or, on rare occasion, pouch excision. Factors that are associated with an increased risk of pouchitis include primary sclerosing cholangitis, extraintestinal manifestations, and nonsmokers. Controversy surrounds other risk factors such as extent of colitis, backwash ileitis, preoperative pANCA levels, and carrying a specific allele for IL-1 receptor antagonist. The etiology of pouchitis is unknown, but theories range from genetic susceptibility, bacterial overgrowth, ischemia, and fecal stasis, to a recurrence of ulcerative colitis in the pouch, a missed diagnosis of Crohn’s disease, or possibly a novel third form of inflammatory bowel disease. Some patients with symptoms of pouchitis will not have inflammation of the pouch, but rather, irritable pouch syndrome. Thus, endoscopic investigation with biopsy is important for declaring whether a patient has pouchitis. Indeed, the more commonly used scores, such as the pouch disease activity index, incorporate both endoscopic and histologic criteria. Not surprisingly, treatment options for patients with pouchitis resemble that of regular inflammatory bowel disease, although there have only been a few controlled trials. Antibiotics are the mainstay of therapy, with metronidazole and ciprofloxacin demonstrating benefit in controlled trials. Probiotics are effective for maintaining remission of pouchitis. Mesalamine, corticosteroids, and immunomodulators have been used with some success. Occasionally, patients with well-documented ulcerative colitis as the indication for IPAA will develop what appears to be Crohn’s disease of the pouch, on the basis of granulomatous inflammation, pre-pouch ileitis, or fistulae. The treatment is similar to Crohn’s disease, including the use of infliximab. Dysplasia within the pouch mucosa itself is quite rare. Reports of dysplasia occurring in patients with IPAA are usually due to neoplastic change within the residual cuff of rectal or transition zone mucosa just below the pouch, rather than in the ileal mucosa of the pouch. With further elucidation of the genetic basis for inflammatory bowel disease, we should be able to more accurately classify patients with ulcerative colitis and Crohn’s disease genotypically. Hopefully, this will also bring more clarity to the heterogeneous population of patients with pouchitis and allow for more focused therapeutic strategies.
An Applied Analysis of Buyer Equity Perceptions and Satisfaction with Automobile Salespeople

General measures of buyer equity perceptions and disconfirmation have been shown to influence satisfaction with and intention towards the salesperson. In this article, specific and thus controllable salesperson and customer equity-related behaviors are shown to be related to satisfaction and intention. In addition, while the general public image of salespeople is thought to be poor, the present study found that buyers rated their salesperson favorably. The results have important implications concerning the public's image of salespeople.
Modes of Metabolic Compensation during Mitochondrial Disease Using the Drosophila Model of ATP6 Dysfunction

Numerous mitochondrial DNA mutations cause mitochondrial encephalomyopathy: a collection of related diseases for which there exists no effective treatment. Mitochondrial encephalomyopathies are complex multisystem diseases that exhibit a relentless progression of severity, making them both difficult to treat and study. The pathogenic and compensatory metabolic changes that are associated with chronic mitochondrial dysfunction are not well understood. The Drosophila ATP61 mutant models human mitochondrial encephalomyopathy and allows the study of metabolic changes and compensation that occur throughout the lifetime of an affected animal. ATP61animals have a nearly complete loss of ATP synthase activity and an acute bioenergetic deficit when they are asymptomatic, but surprisingly we discovered no chronic bioenergetic deficit in these animals during their symptomatic period. Our data demonstrate dynamic metabolic compensatory mechanisms that sustain normal energy availability and activity despite chronic mitochondrial complex V dysfunction resulting from an endogenous mutation in the mitochondrial DNA. ATP61animals compensate for their loss of oxidative phosphorylation through increases in glycolytic flux, ketogenesis and Kreb's cycle activity early during pathogenesis. However, succinate dehydrogenase activity is reduced and mitochondrial supercomplex formation is severely disrupted contributing to the pathogenesis seen in ATP61 animals. These studies demonstrate the dynamic nature of metabolic compensatory mechanisms and emphasize the need for time course studies in tractable animal systems to elucidate disease pathogenesis and novel therapeutic avenues.
Sonographic measurement of relative renal volume in children: comparison with scintigraphic determination of relative renal function.

OBJECTIVE Observer error in the sonographic estimation of renal volume in children has not been reported. Knowledge of the possible magnitude of error is important in assessing abnormalities of renal growth. This study was undertaken to determine the error of sonographic measurements of relative renal volume by comparing them with measurements of relative renal function from 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy. MATERIALS AND METHODS The study included 52 children, 2 months to 16 years old, who had DMSA scintigraphy and renal sonography on the same day. The sonographic and scintigraphic studies were interpreted independently. Relative function of the right kidney as shown by DMSA scintigrams in the direct posterior view was compared with relative volume as determined with sonography. Renal volumes were calculated by using the formula for a prolate ellipsoid. The standard deviation of the differences (SDD) between relative renal function and relative renal volume was calculated, and the limits of agreement were derived. RESULTS Thirty-three children had normal renal morphology on both studies. Twenty-five kidneys in 19 children were abnormal on one or both studies, including 14 definitely scarred kidneys in 12 children. Relative function of the right kidney in patients with normal kidneys was 50.1 +/- 2.5%, including one possible outlying value. Normal relative volume of the right kidney was 49.1 +/- 3.1%. In patients with normal kidneys, the difference between relative function and relative volume of the right kidney was 1.0 +/- 2.8% with 95% limits of agreement of 6.7% and -4.7%. Agreement between relative function and relative volume was worse for children with abnormal kidneys; the mean difference was 2.0%, and the largest observed difference was 10.9%. Correlation between relative renal volume and relative renal function for all patients was high (r = .94), with 95% limits of agreement of 8.6% and -5.8%. CONCLUSION The agreement between relative renal function and relative renal volume was good. In children with normal kidneys, estimated relative renal volume derived from sonography can be expected to lie within 6.7% of the relative renal function determined scintigraphically.
Online mvbf adaptation under diffuse noise environments with mimo based noise pre-filtering

A noise-robust MVBF adaptation technique under diffuse noise environments is proposed. The proposed method is compatible with online adaptation and robustness against diffuse noise by combining a semi-online diffuse noise reduction and an online MVBF adaptation technique with sparseness assumption of speech sources. The online sparseness based MVBF adaptation is sensitive to diffuse noise, because diffuse noise is not sparse. However, by using diffuse noise pre-filtering based on local Gaussian modeling which can be regarded as an optimized MIMO(Multi-Input Multi-Output) diffuse noise reduction method from the probabilistic perspective, sparseness of the microphone input signal into the latter part is expected to be improved. The proposed method is evaluated by using speech signal under diffuse noise environments, and the proposed method can reduce more noise source with less distortion than the conventional online sparseness based MVBF adaptation.
