In the development of a syllable-centric Automatic Speech Recognition (ASR) system, segmentation of the acoustic signal into syllabic units is an important stage. Although the short-term energy (STE) function contains useful information about syllable segment boundaries, it has to be processed before segment boundaries can be extracted. This paper presents a sub-band based group delay approach ...

Microsatellites were isolated and characterized in the northern house mosquito, Culex pipiens , a widespread pest species and important vector of diseases such as West Nile virus. An enrichment protocol yielded 150 positive clones. We designed primers to amplify 17 unique (GT) n microsatellites, eight of which amplified cleanly and were polymorphic. A survey of 29 individuals showed that these ...

Stock prices are a form of time series data. There have been many existing business and economics based methods for predicting stock prices. These methods can be classed as fundamental and technical analysis. Technical analysis is based on the observing patterns in stock prices based on psychological effects (fear and greed) changing supply and demand. Fundamental analysis is based on observing...

A unique community of four syntopic eagle species exists in north-central Kazakhstan. Questions about behaviour and genetics in these four species would benefit from the development of microsatellite markers. We isolated eight polymorphic microsatellite repeats (AAAG) n from the eastern imperial eagle ( Aquila heliaca ) genome using a hybridization enrichment technique. These loci revealed mode...

BACKGROUND The injection of double-stranded RNA (dsRNA) has been shown to induce a potent sequence-specific inhibition of gene function in diverse invertebrate and vertebrate species. The homology-dependent posttranscriptional gene silencing (PTGS) caused by the introduction of transgenes in plants may be mediated by dsRNA. The analysis of Caenorhabditis elegans mutants impaired with dsRNA-medi...

Preprocessing of speech signals is considered a crucial step in the development of a robust and efficient speech or speaker recognition system. In this paper, we present some popular statistical outlier-detection based strategies to segregate the silence/unvoiced part of the speech signal from the voiced portion. The proposed methods are based on the utilization of the 3 σ edit rule, and the Ha...

Global environmental change has negative impacts on ecological systems, impacting the stable provision of functions, goods, and services. Whereas effects of individual environmental changes (e.g. temperature change or change in resource availability) are reasonably well understood, we lack information about if and how multiple changes interact. We examined interactions among four types of envir...

objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...
