در این مقاله، روش جدیدی برای تخمین نسبت سیگنال به نویز (snr) سیگنال ترکیب ارائه شده است که بر پایه روش آنالیز ترکیب شنیداری محاسباتی (casa) است. در روش ارائه شده، ماسک باینری ایده آل (ibm) که به طور معمول هدف محاسباتی سیستم های مبتنی بر casa است، برای تخمین snr سیگنال گفتار نویزی به کار گرفته می شود. روش پیشنهادی با استفاده از ibm و چندین ماسک شبه ibm ارزیابی شده است. این روش، ساده و از نظر محا...

Microbiological characterization of frescos in four different locations (Collegio degli Augustali, Casa del Colonnato Tuscanico, Casa dello Scheletro and Casa del Gran Portale) of excavation sites of Herculaneum was carried out. The use of infrared thermography allowed detecting sample points on frescos with greatest moisture not visible to the naked eye, resulting in structural damage. The mic...

We prospectively assessed stool samples from 370 patients for Campylobacter species by comparing three selective agar media incubated at two temperatures: 42°C and 37°C. Twenty patients (5.4%) were found positive. The chromogenic medium CASA (AES Chemunex, France) proved highly efficient for C. jejuni and C. coli recovery, while lessening the workload in the lab.

Digital music making is evolving dramatically with today's increasing availability of free music software and musical content. Digitópia, a platform for collaborative music creation recently started at Casa da Música, Porto's main concert venue, addresses how these trends can affect generalized music creation and music software design, promote social inclusion, and lead to the emergence of mult...

BACKGROUND Cough and sputum production are frequent in chronic obstructive pulmonary disease (COPD). The objective of this study was to examine the relationship between cough and sputum production and health-related quality of life in COPD. METHODS A cross-sectional study was conducted in the French Initiatives COPD cohort and assessed cough and sputum production within the past 7 days using ...

The problem of segregating a sound source of interest from an acoustic background has been extensively studied due to applications in hearing prostheses, robust speech/speaker recognition and audio information retrieval. Computational auditory scene analysis (CASA) approaches the segregation problem by utilizing grouping cues involved in the perceptual organization of sound by human listeners. ...

Both genetic and environmental influences contribute to the wide variation in plasma von Willebrand factor (VWF) levels observed in humans. Inbred mouse strains also have highly variable plasma VWF levels, providing a convenient model in which to study genetic modifiers of VWF. Previously, we identified a major modifier of VWF levels in the mouse (Mvwf1) as a regulatory mutation in murine Galgt...

As the United States marks 50 years since the beginning of the Great Society social programs initially intended to end rural poverty the results of this endeavor are far from complete. Over eighty percent of the most impoverished counties in the United States are rural with double digit unemployment and limited potential for economic growth. Although traditional welfare transfer structures have...
