Deep Neural Networks (DNNs) are becoming widely accepted in automatic speech recognition (ASR) systems. The deep structured nonlinear processing greatly improves the model’s generalization capability, but the performance under adverse environments is still unsatisfactory. In the literature, there have been many techniques successfully developed to improve Gaussian mixture models’ robustness. In...
Cronobacter spp. (previously known as Enterobacter sakazakii) is a bacterial pathogen affecting all age groups, with particularly severe clinical complications in neonates and infants. One recognized route of infection being the consumption of contaminated infant formula. As a recently recognized bacterial pathogen of considerable importance and regulatory control, appropriate detection, and id...
This paper discusses non-filter waveform generation from cepstral features using spectral phase reconstruction as an alternative method to replace the conventional source-filter model in text-to-speech (TTS) systems. As the primary purpose of the use of filters is considered as producing a waveform from the desired spectrum shape, one possible alternative of the sourcefilter framework is to dir...
The O-antigen is a highly diverse structure expressed on the outer surface of Gram-negative bacteria. The products responsible for O-antigen synthesis are encoded in the wbe region, which exhibits extensive genetic diversity. While heterogeneous O-antigens are observed within Vibrio species, characterization of these structures has been devoted almost exclusively to pathogens. Here, we investig...
A novel strain Vibrio aphrogenes sp. nov. strain CA-1004T isolated from the surface of seaweed collected on the coast of Mie Prefecture in 1994 [1] was characterized using polyphasic taxonomy including multilocus sequence analysis (MLSA) and a genome based comparison. Both phylogenetic analyses on the basis of 16S rRNA gene sequences and MLSA based on eight protein-coding genes (gapA, gyrB, fts...
The microbial etiology of dental caries is still debated. Among the hypothesized contributors are the "low pH streptococci," a designation given to unusually acid proficient strains among the primary plaque colonizers S. oralis, S. mitis, S. gordonii, and S. anginosus. However, accurate assignment of species is difficult among the oral streptococci. Our objective was to develop a streamlined me...
The set of cell surface determinants encoded by the MHC is remarkable in that it is recognized by naive T cell populations at a sufficiently high precursor frequency to induce substantial primary proliferative responses, and the critical biologic role played by MHC products has been well established . The only other determinants capable of inducing strong proliferative responses by naive T cell...
زوال درختان جنگلی بیماری پیچیده ای است که نمی توان آن را تنها به یک عامل نسبت داد. نمونه برداری های اخیر شواهدی مبنی بر بروز اپیدمی جدید در درختان بلوط جنگل های شمال ایران دارد. به همین منظور از درختانِ بلوطِ آلوده به شانکر مناطق مختلف، پرگنه های باکتریایی جدا و برای شناسایی و اثبات بیماریزایی مورد آزمون های بیوشیمیایی، فیزیولوژیکی، مولکولی و الکتروفورز پروتئین قرار گرفتند. جدایه های به دست آمده ...
