The AASM has made an important update to the recommendation regarding use of adaptive servo-ventilation (ASV) for treatment of central sleep apnea syndromes (CSAS) related to chronic heart failure (CHF). This update stems from the May 2015 ResMed Field Safety Notice indicating that patients with symptomatic CHF and reduced left ventricular ejection fraction (LVEF ≤45%) using ASV for treatment o...

Transition metal defects were studied in different polytypes of silicon carbide (SiC) by ab initio supercell calculations. We found asymmetric split-vacancy (ASV) complexes for these defects that preferentially form at only one site in hexagonal polytypes, and they may not be detectable at all in cubic polytype. Electron spin resonance study demonstrates the existence of ASV complex in niobium ...

In a recent issue of CHEST (June 2015), we read with interest the randomized controlled trial (RCT) by Kirakli et al comparing adaptive support ventilation (ASV) with pressure assist/control ventilation (P-ACV) for the entire duration of mechanical ventilation (MV) in a cohort of 229 patients in the medical ICU. The study showed a shorter duration of the weaning process and total MV in the ASV ...

Svrha SERVE-HF istraživanja bila je da se procijene učinci adaptivne servoventilacije (ASV) koja pruža servokontroliranu potporu udisajnoga tlaka povrh pozitivnoga izdisajnog tlaka u pacijenata s umjerenim do ozbiljnim stupnjem ZS-a i EF < 45 % koji su imali većinom centralnu apneju u snu.1 U ovoj je studiji 1325 pacijenata bilo randomizirano u skupine liječene ASV-om (666) i kontrolnom terapij...

Anodic stripping voltammetry (ASV) with rotating glassy carbon electrode (RGCE) and microfiber carbon electrode (μFCE), both filmed with mercury, were used to determine copper content in wine. Influence of phenolics on in situ mercury film formation was studied. Wine and quercetin were added gradually into solution of Hg(II) in acetic acid-sodium acetate buffer (pH = 4.60). Reduction of Hg(II) ...

Today major section of automatic speaker verification (ASV) research is focused on multiple objectives like optimization of feature subset and minimization of Equal Error Rate (EER). As such, numerous systems for feature dimension reduction are proposed. This includes framework coaching and testing analysis for every feature set that could be a time esurient trip. Because of its significance, t...

BACKGROUND & OBJECTIVE The expression of human telomerase reverse transcriptase (hTERT) is positively correlated to the activity of telomerase. Alternative splicing exists in the transcription of hTERT and special splicing patterns may change during tumor progression. This study was to reveal the changes of hTERT alterative splicing pattern in gastric carcinogenesis. METHODS Three alternative...

For practical automatic speaker verification (ASV) systems, replay attack poses a true risk. By replaying a pre-recorded speech signal of the genuine speaker, ASV systems tend to be easily fooled. An effective replay detection method is therefore highly desirable. In this study, we investigate a major difficulty in replay detection: the over-fitting problem caused by variability factors in spee...
