Speech emotion recognition using RBF kernel of LIBSVM

Automatic Speech Emotion Recognition (SER) is a current research topic in the field of Human Computer Interaction (HCI) with wide range of applications. The speech features such as, Mel Frequency cepstrum coefficients (MFCC) and Mel Energy Spectrum Dynamic Coefficients (MEDC) are extracted from speech utterance. The LIBSVM is used as classifier to identify different emotional states such as anger, happiness, sadness, neutral, fear, from Berlin emotional database. The results are taken by using RBF kernel of LIBSVM. It gives 93.75% recognition accuracy for RBF kernel.
Helicobacter pylori infection in intestinal- and diffuse-type gastric adenocarcinomas.

Gastric cancer can be divided into two histologic types: intestinal and diffuse. To determine whether Helicobacter pylori, a bacterium linked with gastritis, was associated with either cancer type, we reviewed histologic sections from stomachs of patients who had undergone gastrectomy for gastric cancer. Of 37 of the sections with evidence of intestinal-type cancer, 33 (89.2%) contained H pylori in noncancerous tissue compared with 7 (31.8%) of 22 of the sections with evidence of diffuse-type cancer (odds ratio = 17.7; P less than .001). This association remained strong when controlled for age, sex, site, and number of sections reviewed. The prevalence of H pylori in intestinal-type gastric cancer far exceeded the prevalence of H pylori in diffuse disease and that described in the normal US population. This finding suggests that H pylori may be a cofactor in development of intestinal-type gastric cancer.
A 9.99 mW low-noise amplifier for 60 GHz WPAN system and 77 GHz automobile radar system in 90 nm CMOS

A low-power and wideband two-stage millimeter-wave low-noise amplifier (LNA) for 60 GHz WPAN (wireless personal area network) system and 77 GHz automotive radar system using standard 90 nm CMOS technology is reported. T-match technique is utilized to achieve simultaneously wideband input and output impedance matching, wideband power gain (S21) and wideband NF at both 60-GHz-band and 77-GHz-band. The LNA consumes only 9.99 mW, achieving S11 better than -10 dB for frequencies of 57.6~81.8 GHz, and S12 better than -29.1 dB for frequencies of 10~110 GHz. Additionally, high and flat S21 of 11.2±1.5 dB is achieved for frequencies of 57.9~80.4 GHz, which means the corresponding 3-dB bandwidth is 22.5 GHz. Furthermore, the LNA achieves minimum noise figure (NF) of 4.8 dB at 76 GHz and NF of 6.2±1.4 dB for frequencies of 76~84 GHz, one of the best NF results ever reported for a W-band CMOS LNA. At 79 GHz, the measured input 1 dB compression point (P1dB) and input third-order intercept point (IIP3) are -18.7 dBm and -7.4 dBm, respectively.

Correlation Analysis of Reactive Power Control Mode of DFIG WTGs and System Frequency Stability

Although doubly-fed induction generator (DFIG) can realize the active, reactive power decoupling control by using stator flux orientation vector control technique, the choice of its reactive power control mode is still has profound impact on system frequency stability. At present, there are two control modes of DFIG, i.e., constant power factor control mode and constant voltage control mode. Through analyzing the power characteristics of DFIG WTGs, this paper presents a coupling expression between reactive control mode of DFIG WTGs and system frequency deviation, and then analyzes the impact of reactive power control mode on system frequency stability. At last, take PSS/E and WIND Package as simulation platform, the validity and rationality of theoretical analysis are verified by numerical simulation. Research results show that, whether wind speed variation, load disturbance or short circuit faults, constant power factor control mode is all conducive to system frequency stability.
Role of RNF 4 in the ubiquitination of Rta of Epstein-Barr virus

Background: Rta is a transcription factor encoded by Epstein-Barr virus (EBV), which activates the transcription of vial lytic genes and promotes lytic development. Results: RNF4 enhances the ubiquitination of Rta, thus decreasing lytic replication and virions production. Conclusions: RNF4 targets SUMO-2-conjugated Rta and promotes Rta’s ubiquitination. Significance: RNF4 is an STUbL of Rta to modulate the amount of Rta during EBV lytic progression.
Mitochondrial Biogenesis and Thyroid Status Maturation in Brown Fat Require CCAAT/Enhancer-binding Protein α*

Brown fat differentiation in mice is fully achieved in fetuses at term and entails the acquisition of not only adipogenic but also thermogenic and oxidative mitochondrial capacities. The present study of the mice homozygous for a deletion in the gene for CCAAT/enhancer-binding protein α (C/EBPα-null mice) demonstrates that C/EBPα is essential for all of these processes. Developing brown fat from C/EBPα-null mice showed a lack of uncoupling protein-1 expression, impaired adipogenesis, and reduced size and number of mitochondria per cell when compared with wild-type mice. Furthermore, immature mitochondrial morphology was found in brown fat, but not in liver or heart, from C/EBPα-null mice. Concordantly, expression of both nuclear and mitochondrial genome-encoded genes for mitochondrial proteins was reduced in C/EBPα-null brown fat, although expression of mitochondrial rRNA and mitochondrial DNA content were unaltered. Expression of nuclear respiratory factor-2, thyroid hormone nuclear receptors, and peroxisome proliferator-activated receptor γ coactivator-1, was delayed in C/EBPα-null brown fat. Iodothyronine 5′-deiodinase activity and thyroid hormone content were also reduced in brown fat from C/EBPα-null mice, indicating for the first time a crucial role for C/EBPα in controlling thyroid status in developing brown fat, which may contribute to impaired mitochondrial biogenesis and cell differentiation. When survival of C/EBPα-null mice was achieved by transgenically expressing C/EBPα only in the liver, a substantial recovery in brown fat differentiation was found by day 7 of postnatal age, which is associated with a compensatory overexpression of C/EBPδ and C/EBPβ.
Addition of Supplementary Foods and Infant Growth (2 to 24 Months)

Objective: To determine the effect of adding supplementary foods on infant growth 2 to 8 and 12 to 24 months. Methods: Length (cm/month) and weight (kg/month) of white infants (n = 94) were measured five to nine times from 2 to 24 months of age. Mothers reported birth weights, infants’ ages at first introduction of supplementary food, illnesses and information sources about infant feeding. Simple linear regression equations were used to compute slopes for each child (unit changes in length and in weight by age). Stepwise linear regression was used to determine the effect on weight and length slopes by the introduction of supplementary foods (e.g., an infant’s age when cereal, fruit, juice, vegetables and a meat cluster were first added) to the diet. Breast feeding (months duration or ever fed), illness scores and gender were covariates in the regression models. Results: A significant model (F = 10.09, p = .002) for weight gain (2 to 8 months) showed that gender explained 10% of the variance; for length slope, the model was non-significant and gender explained 3% of the variance. Females had a slower weight gain compared to that of males. None of the covariates or supplementary foods were retained in the models. Weight prior to 12 months was the best predictor (p = .0001, 54% of the variance) of weight gain 12 to 24 months. Conclusions: Unit changes in weight or length for an infant’s age were not statistically associated with the timing of when supplementary foods were first added to the diet 2 to 8 or 12 to 24 months. Weight prior to 12 months was a significant predictor of weight gain 12 to 24 months.
PRECISION ONCOLOGY : IS IT POSSIBLE ?

The article is on a recent approach to Precision Oncology based in the application of a computationally intensive approach to personalized medicine by means of a reverse engineering methodology termed rapid learning that considers individual patients both as a part of a cohort or corpus in an intelligent database and as individuals in an ongoing clinical practice setting. Some of the challenges and shortcomings are discussed.
Relationships among independent major depressions, alcohol use, and other substance use and related problems over 30 years in 397 families.

OBJECTIVE Although heavy drinking is related to sadness on multiple levels, the link between alcohol use disorders (AUDs) and major depressive episodes (MDEs) is more controversial. One complicating factor is that some MDEs are temporary and only occur in the context of heavy drinking, whereas other MDEs are longer lasting and occur independently of intense alcohol intake (i.e., independent depressive episodes [IDEs]). We hypothesized that a longitudinal study that uses validated interviews with subjects and relatives and distinguishes between IDEs and alcohol-induced depressive episodes would reveal little evidence of a link between IDEs and AUDs. METHOD Histories of AUDs, IDEs, and substance-induced depressions were prospectively evaluated over 30 years in 397 male probands from the San Diego Prospective Study and in their 449 offspring using questions extracted from the Semi-Structured Assessment for the Genetics of Alcoholism interview. RESULTS The rate of IDEs over 30 years in the 397 probands was 15.3% overall. Among probands who developed AUDs, 31% of their depressive episodes were substance induced, not IDEs. For these men followed over 3 decades, those with IDEs had no increased rate of AUDs and evidenced no higher rate of use or abuse/dependence on illicit substances. Similar conclusions applied to their 449 offspring ages 12 years and older. CONCLUSIONS These data support the importance of distinguishing between IDE and substance-induced depressions when evaluating the relationship between AUDs and depression syndromes.
Cochlear implants.

This book focuses on studies related to cochlear implants (and to a lesser extent auditory brainstem implants) performed at the Research Triangle Institute over two decades. By doing so, it provides the reader with an insight into how this field has evolved, culminating in the modern cochlear implant (CI). Four major lines of investigation are followed: design and evaluation of novel processing strategies; electrical stimulation on both sides with CIs; combined electric and acoustic stimulation of the auditory system; and representations of temporal information with CIs. What strikes me about this book is that it reads like a compilation of reports or publications, rather than a standard textbook that aims to give an overview of CIs. Indeed, there are a lot of unpublished data that may be of interest to certain readers. A detailed analysis of each subject and processor type is presented very clearly, using various figures. The in-depth explanation of the various processing strategies is really pitched at readers who are wellversed in this subject (not so much ENT surgeons making their first foray into this area). A summary at the end of chapters is a rarity rather than the norm, which is a shame. This book beautifully distils the experience at the Research Triangle Institute. I do not feel it is a starter text for someone wishing to learn about CIs. Priced at over £100, you would need a strong reason to buy this book over other, cheaper alternatives.
Case Report: Information Resources Used in Antimicrobial Prescribing

To describe resources clinicians use when they prescribe antimicrobials, the authors surveyed prescribers by telephone within hours (median 2.9) after they ordered one or more antimicrobials for a patient. Among 157 prescribers, 87 (55%) used one or more external resources to aid in decisions about their order. The other 70 (45%) used only their own knowledge and experience. Fifty-nine (38%) consulted another person. Fifty-four (34%) used a print, computer, or Internet resource. In multivariate analysis, use of an external resource was associated with the clinician being on the medical service (odds ratio [OR] 2.99, 95% confidence interval [CI] 1.41-6.3) or being an intern (OR 13.65, 95% CI 1.44-128). Eighty percent of providers said information about antimicrobial prescribing at the point of electronic order entry would be helpful. It was concluded that decision support at the point of electronic order entry is likely to be used and might improve antimicrobial prescribing.
Evasão na educação superior e gestão institucional: o caso da Universidade Federal da Paraíba

Resumo O estudo objetiva analisar os movimentos da evasão na educação superior, através do caso específico da Universidade Federal da Paraíba (UFPB). A ideia é demonstrar as consequências econômicas e sociais da evasão para a gestão universitária, para a instituição educativa e a sociedade de forma geral. A metodologia aplicada foi uma análise documental da situação da evasão na UFPB e estudo longitudinal retrospectivo das taxas de evasão escolar ocorridas nos seus cursos de graduação presencial, no período do Reuni, de 2007 a 2012, e após o seu término. Os resultados mostram que na vigência do Reuni, a taxa anual de evasão ao nível da instituição ficou quase inalterada, em torno de 15%, mas, posteriormente, vem apresentando uma crescente elevação. Quando, desagregados por Centro de Ensino, os dados apresentam um panorama ambivalente com diminuição e aumento do fenômeno, e uma quantidade de diplomados menor do que o número dos ingressantes. Em virtude desse fenômeno, as perdas financeiras da instituição giraram em torno de R$ 415 milhões, isso, sem considerar as perdas sociais, fragilizando seus propósitos educacionais, sociais e de desenvolvimento local.
Cooley-Tukey FFT like algorithm for the discrete triangle transform

The discrete triangle transform (DTT) was recently introduced (Pu/spl uml/schel, M. and Ro/spl uml/tteler, M., Proc. ICASSP, 2004) as an example of a non-separable transform for signal processing on a two-dimensional triangular grid. The DTT is built from Chebyshev polynomials in two variables in the same way as the DCT, type III, is built from Chebyshev polynomials in one variable. We show that, as a consequence, the DTT has, like the type III DCT, a Cooley-Tukey FFT type fast algorithm. We derive this algorithm and an upper bound for the number of complex operations it requires. Similar to most separable two-dimensional transforms, the operations count of this algorithm is O(n/sup 2/ log(n)) for an input of size n/spl times/n.
Cognitive and affective predictors of boredom proneness

ABSTRACT Boredom proneness has been linked to various forms of cognitive and affective dysregulation including poor self-control and mind-wandering (MW), as well as depression and aggression. As such, understanding boredom and the associated cognitive and affective components of the experience, represents an important first step in combatting the consequences of boredom for psychological well-being. We surveyed 1928 undergraduate students on measures of boredom proneness, self-control, MW, depression and aggression to investigate how these constructs were related. Hierarchical regression analysis indicated that self-control operated as a strong negative predictor of boredom proneness. Finally, when controlling for age and self-control, we observed large decreases in the magnitudes of the relationships between boredom proneness and our other measures of interest. Together, these results imply a strong relationship between boredom proneness and cognitive and affective dysregulation, and show that individual levels of self-control can account for the lion’s share of variance in the relationships between boredom, cognition, and affect.
Perinatal Maturation of the Auditory Brain Stem Response: Changes in Path Length and Conduction Velocity

Objective: The goal of this study was to correlate developmental data on brain stem auditory path length with data on auditory brain stem response (ABR) conduction time. This was done to estimate changing axonal conduction velocity during the perinatal period. Design: Pathway length was determined by three‐dimensional reconstruction of postmortem fetal and infant brain stems in an AutoCAD system. Brain stem conduction time was obtained from previous ABR studies of premature, term, and post‐term infants. The process of correlation of path length and conduction time was based on a model of ABR generation(Ponton, Moore, & Eggermont, this issue) that assumes that the III‐IV interpeak interval represents activity in an asynaptic pathway and, thus, consists of only axonal conduction time. Results: Brain stem conduction time is adult‐like by the time of term birth. However, the brain stem auditory pathway continues to lengthen postnatally, with portions of the pathway not reaching adult dimensions until 3 yr of age. We determined lengths at various perinatal ages for three different segments of the auditory pathway. Each segment began at the cochlear nucleus (site of wave III generation) and ended at a more rostral location that is a possible site of wave IV generation. Conduction velocity was estimated by dividing path length by axonal conduction time (III‐IV interpeak interval). All three assumed sites of generation of wave IV gave estimates of a threefold increase in conduction velocity between 29 wk CA and adulthood. However, three highly discrepant measures of absolute conduction velocity were obtained for the different path segments. The most reasonable conduction velocity estimates, from 5 m/sec at 29 wk conceptional age to 20 m/sec in adults, were produced by assuming a site of generation for wave IV near the contralateral medial superior olivary nucleus. Conclusions: Prenatally, increasing conduction velocity more than compensates for increasing path length, causing ABR conduction time to decrease. Postnatally, increasing conduction velocity exactly compensates for increasing path length while ABR conduction time remains stable. Different aspects of myelin development may underlie these two phenomena.
Lower-Tropospheric Humidity–Temperature Relationships in Radiosonde Observations and Atmospheric General Circulation Models

Abstract Annual and seasonal correlations between temperature and both specific and relative humidity are presented based on radiosonde station data over the tropical Pacific Ocean and North America. Results are presented for the surface and the 850-, 700-, and 500-hPa levels. The correlations between anomalies of temperature and relative humidity are generally negative, and those between temperature and specific humidity are generally positive. Longitudinal differences in the pattern of correlations are found both in low latitudes and over midlatitude North America. In particular, near-zero or negative temperature–specific humidity correlations are found in the western United States at and below 700 hPa (especially in summer) and over the western tropical Pacific at 700 and 500 hPa (especially in winter). The observed correlation patterns are compared with those of 12 atmospheric general circulation model (AGCM) simulations. Simulated high-latitude correlation patterns qualitatively agree with observatio.
In silico miRNA Target Identification within the Human Peroxisome Proliferator Gene

MicroRNAs (miRNAs), an abundant class of 21 eukaryotic gene expression and therefore implicated in a wide range of biological processes. The miRNA related genetic alterations are possibly more implicated in human diseases than miRNA target prediction using bioinformatics tools is often the first line approach in studying gene regulation. Such predictions will help in setting search priorities for experimental validation of gene controlling mechanisms. But finding a functional miRNA target in the human genome yet remains a challenging task. In the present study, miRNA target sites within the complete sequences (5 and 3′ UTR) of human PPARG gene were investigated using miRwalk database. We found 26 different miRNA target sites within the 5 computational approach will subsequently allow better networks in cellular systems.
Pancreaticoduodenectomy for periampullary adenocarcinoma.

BACKGROUND This study evaluates the indications for and effects of pancreaticoduodenectomy (102 patients) or total pancreatectomy (15 patients) with extensive lymph node dissection performed upon 117 patients for treatment of periampullary adenocarcinoma. STUDY DESIGN Presenting symptoms and postoperative morbidity and mortality rates were recorded. Cumulative survival rates were evaluated in relation to origin, size, and staging of tumor. Postoperative follow-up of clinical symptoms was done after one year. RESULTS The postoperative mortality rate after Whipple's operation was 8 percent (eight patients). The median survival period was 1.1 year and the overall five year survival rate was 15 percent (confidence limits, 5 to 25 percent). The five year survival rate for patients without tumor extension beyond the pancreas was 25 percent (confidence limits, 5 to 50 percent), and in patients with adenocarcinoma of the ampulla of Vater, 34 percent (confidence limits, 3 to 65 percent). The median survival rate in patients with adenocarcinoma of the ampulla of Vater was 3.3 years, which was significantly longer than in the other patients. Fifty-nine patients with distant spread could be divided into 14 patients with para-aortic lymph node metastases who had a significantly shorter survival period than 45 patients without para-aortic lymph node metastases (p = 0.004). Most patients surviving more than one year were doing well, although 60 percent needed exocrine pancreatic substitution therapy. CONCLUSIONS Resection of periampullary carcinoma provides a better palliation and survival rate than nonoperative biliary drainage or bypass operation. An improved preoperative verification of para-aortic metastases could restrict resection to patients with a prognostic five year survival rate of more than 25 percent and a postoperative mortality rate of less than 5 percent.
Adaptation and coping following a first stroke: a qualitative analysis of a phenomenological orientation

Stroke can have consequences in all areas of a person's life. If not coped with optimally, this life event will have a deleterious effect on the quality of life. The aim of this study was to improve understanding of appraisal and coping, post-stroke. Ten individuals were purposely recruited upon admission for a first stroke to participate in this qualitative study. Participants were asked to share their personal experiences with regard to their efforts to deal with the consequences of the stroke. In-depth interviews were transcribed verbatim and the content was analyzed using a rigorous method, inspired by a phenomenological orientation. Seven themes related to appraisal (unpredictability, overwhelming, feeling out of control, threat, turning point, acceptance/resignation and future prospects) and five themes related to coping (active and passive compensation, escape, change how the situation is perceived and utilization of resources) emerged from the content analysis of the in-depth interviews. In conclusion, since returning to the previous life style and activities is rather improbable, changing how the situation is perceived appears to be the most effective way of coping, in order to reach a state of acceptance/resignation favourable to an optimal quality of life.
