In this paper, we present an algorithm for Voice Activity Detection (VAD) in speech signals using the minimum phase group delay function. The proposed method considers a buffer consisting of contiguous frames of the given signal and computes the short-term energy (STE) for that buffer. By appending a surrogate signal to STE and viewing the resultant signal as a positive part of the magnitude sp...

The Short Time Exposure (STE) test is a simple and easy-to-perform in vitro eye irritation test, that uses the viability of SIRC cells (a rabbit corneal cell line) treated for five minutes as the endpoint. In this study, our goal was to define the applicability domain of the STE test, based on the results obtained with a set of 113 substances. To achieve this goal, chemicals were selected to re...

A plethora of organic micropollutant mixtures are found in untreated municipal wastewater. Anaerobic digesters receive large loadings of hydrophobic micropollutants that sorb to wastewater biosolids. Despite micropollutants being pervasive as mixtures, little research is available to explain the impact that mixtures of compounds, as well as exposure time, have on microbial communities in anaero...

The stem terminus element (STE), which was discovered 13 y ago in human telomerase RNA, is required for telomerase activity, yet its mode of action is unknown. We report that the Schizosaccharomyces pombe telomerase RNA, TER1 (telomerase RNA 1), also contains a STE, which is essential for telomere maintenance. Cells expressing a partial loss-of-function TER1 STE allele maintained short stable t...

Abstract Funding Acknowledgements Type of funding sources: None. Background ARNI has been shown to be superior enalapril in long term reducing the mortality and hospitalization heart failure (HF). However short-term effect on diastolic function remain unclear. We sought evaluate 6 months" effects left ventricular (LV) parameters determined by speckle tracking tissue Doppler imaging. Objectives ...

To date, few natural cases of RNA-silencing-mediated regulation have been described. Here, we analyzed repression of testis-expressed Stellate genes by the homologous Suppressors of Stellate [Su(Ste)] repeats that produce sense and antisense short RNAs. The Stellate promoter is dispensable for suppression, but local disturbance of complementarity between the Stellate transcript and the Su(Ste) ...

background: marital adjustment is one of the most extensive concepts to determine and show the happiness and stability rate of couples’ relationship. marital adjustment affects on different dimensions of individuals’ personal and social life. the purpose of this research is to study the effect of solution- focused short-term couple therapy on women’s marital adjustment increase in qom in 2012. ...

abstract background: we aimed to evaluate an approach to induced abortions during early pregnancies that controls the suction pressure and restricts the duration of the procedure. methods: three hundred patients programmed for induced early pregnancy abortions, hospitalized in the shandong provincial maternity & child care hospital from october 2013 to october 2015, were enrolled. patients were...
