introduction ventilator-associated pneumonia (vap)  is one of the most serious and  prevalence of  complication  among patients in the intensive care unit nosocomial infections, which are often recognized after detecting symptoms. to date, there has been no proper clinical and diagnostic marker for early detection of this disease. in this study, two hcn4 and adam8 genes in patients with vap wer...

background: leishmaniasis is a parasitic disease caused by different species of leishmania parasites with a wide range of clinical manifestations . antimonial compounds such as meglumine antimoniate (glucantime) are the first line drugs for the treatment of leishmaniasis. however, according to reports of the drug resistance of parasites, the efficacy of antimonial compounds is low. the atp-bind...

When we speak in an environment with noise, we often modify our speech production, and speech spoken in noise is generally more intelligible than speech produced in a quiet environment, which is known as the Lombard effect. Our goal is to provide intelligible speech announcements in noisy and/or reverberant public spaces, such as train stations. Thus, the present paper examines whether speech s...

Determination of the rate of energy loss in a reverberation chamber is fundamental to many different measurements such as absorption cross-section, antenna efficiency, radiated power, and shielding effectiveness. Determination of the energy decay time-constant in the time-domain by linear fitting the power delay profile, rather than using the frequencydomain quality-factor, has the advantage of...

The paper was conducted to assess the importance and challenges encountered in the current machine evaluation system in an electronics company as perceived by the respondents. In addition, it also sought to understand the acceptability of the new developed Real-Time Auto-locked Software for Electronics Company (RT-ASEC). The new automated machine evaluation software can detect any irregular mac...

This paper introduces a time-variant reverberation algorithm as an extension of the feedback delay network (FDN). By modulating the feedback matrix nearly continuously over time, a complex pattern of concurrent amplitude modulations of the feedback paths evolves. Due to its complexity, the modulation produces less likely perceivable artifacts and the time-variation helps to increase the livelin...

The main di culty in building robust practical systems for acoustical source localization using microphone arrays, is the e ects of room-reverberation. In this paper, a statistical analysis is presented of the in uence of room reverberation on source localization techniques. Using a statistical reverberation model presented in a companion paper, the Cram erRao lower bound for time-deley estimat...
