Automatic speaker verification (ASV) systems are highly vulnerable against spoofing attacks, also known as imposture. With recent developments in speech synthesis and voice conversion technology, it has become important to detect synthesized or voice-converted speech for the security of ASV systems. In this paper, we compare five different classifiers used in speaker recognition to detect synth...

The ventilatory treatment of patients with heart failure (HF) associated with obstructive sleep apnea (OSA), central sleep apnea (CSA), and Cheyne-Stokes respiration (CSR) remains debated. In a recent study in CHEST (August 2012), Randerath and colleagues 1 compared the effi ciency of auto-servoventilation (ASV) and CPAP in these patients. They report that ASV is superior to CPAP in improving C...

Combined Autonomous Surface Vehicles (ASV) and remotely operated underwater vehicles (ROV) inspection intervention systems can contribute to future asset management of offshore renewable energy. This paper presents the design performance winch system which couples ASV ROV deploys/recovers ROV. The hydrodynamic models control algorithms are developed solved with analytical numerical approaches. ...

The concept of central sleep apnoea or hypoventilation encompasses hypercapnic central hypoventilation, such as obesity hypoventilation syndrome and eucapnic or hypocapnic central sleep apnoea. Among subjects with eucapnic or hypocapnic central sleep apnoea, several therapeutic options are available for those with Cheyne–Stokes respiration (CSR). CSR is frequent in patients with New York Heart ...

In this paper we extend the parametric, asymmetric, stochastic volatility model (ASV), where returns are correlated with volatility, by flexibly modeling the bivariate distribution of the return and volatility innovations nonparametrically. Its novelty is in modeling the joint, conditional, return-volatility, distribution with a infinite mixture of bivariate Normal distributions with mean zero ...

BACKGROUND AND PURPOSE Susceptibility-weighted (SW) MR imaging has enabled noninvasive visualization of the cerebral veins and has shed light on the nature of venous architecture. For successful surgery of the third ventricle, understanding of the anatomy of the subependymal veins of the lateral ventricle and their relationships to the foramen of Monro is required preoperatively. The purpose of...

BACKGROUND The efficacy of a direct-acting antiviral agent (DAA) is compromised by the development of drug resistance. The associations between resistance-associated virus (RAV) and therapeutic outcomes have not been well-understood. METHODS A total of 30 patients with HCV genotype-1b were enrolled and treated for 24 weeks with asunaprevir (ASV) and daclatasvir (DCV). Viral sequences in non-s...

Speciation modeling is an essential tool to estimate the chemical composition of an aqueous sample and to assess the bioavailability and potential risks associated with metal contamination. It is also an indispensable alternative for quantifying the metal speciation when analytical techniques are not available. In this study, we tested the effectiveness of two models, WinHumicV and the Non-Idea...

ment. We saw no systematic error associated with a plot of the residuals (data not shown). The linear model accounted for the data, and the underlying assumptions (linearity, stable variance) of the model have not been violated. The upper limit of linearity was 3.377 mmol/L (700 mg/L), although we routinely used a linear calibration up to 1.930 mmol/L (400 mg/L), which encompassed almost all of...
