Introduction: Specific ventilation (SV) is defined as a dimensionless quantity of inhaled gas ventilation that occurs during tidal breathing and is calculated as tidal volume divided by functional residual capacity [1]. 1H MRI was previously proposed to regionally quantify SV, using inhaled O2 as a contrast agent [2]. Our objective was to develop a novel and rapid way to measure whole lung and ...

The authors propose the use of micro-electric vehicles called “silver vehicles” (SV) as mobility devices for older drivers who have difficulty driving automobiles. Previous reports have described research on characteristics of the elderly, proposed the SV concept and evaluated it in townmobility field tests. This report addresses feasibility of the SV concept and issues of town planning through...

The aim of this paper is to analyze the current evidence on radiocerebral effects following exposure to <5 Sv. Dose-related cognitive and neurophysiological abnormalities among prenatally exposed children after the Chernobyl accident at gestation ages of +8 weeks were revealed at >20 mSv on the fetus and >300 mSv on the thyroid in utero; at 16–25 weeks, abnormalities were >10 mSv and >200 mSv, ...

Sigmoid volvulus (SV) is a rare colonic obstruction in which the sigmoid colonwraps around itself. The principal strategy for the treatment of uncomplicated SV is emergency endoscopic detorsion, while emergency surgery is needed in complicated SV with bowel gangrene, bowel perforation, peritonitis, or unsuccessful endoscopic treatment. In the endoscopic examination of SV, endoscopic detorsion i...

In a dynamical system the singular vector (SV) indicates which perturbation will exhibit maximal growth after a time interval tau . We show that in systems with spatiotemporal chaos the SV exponentially localizes in space. Under a suitable transformation, the SV can be described in terms of the Kardar-Parisi-Zhang equation with periodic noise. A scaling argument allows us to deduce a universal ...

This paper summarizes the main results from the Speaker Veri cation SV research pursued so far in the CAVE project Di erent state of the art SV algo rithms were implemented in a common HMM frame work and compared on two databases YOHO of ce environment speech and SESP telephone speech This paper is concerned with the di erent design issues for LR HMM based SV algorithmswhich emerged from our in...

This paper describes the recognition of micro non-magnetic (conductive) and ferromagnetic material with spinvalve magneto-resistance (SV-GMR) sensor. High frequency and static magnetic fields were applied to material for the recognition of the micro conductive and ferromagnetic material respectively. The SV-GMR sensor is used to detect the magnetic field variation occurred wherever the material...

This paper proposes a class of stochastic volatility (SV) models which offers an alternative to the one introduced in Andersen (1994). The class encompasses all standard SV models that have appeared in the literature, including the well known lognormal model, and allows us to empirically test all standard specifications in a convenient way. We develop a likelihood-based technique for analyzing ...

Structural variation (SV) has been reported to be associated with numerous diseases such as cancer. With the advent of next generation sequencing (NGS) technologies, various types of SV can be potentially identified. We propose a model based clustering approach utilizing a set of features defined for each type of SV events. Our method, termed SVMiner, not only provides a probability score for e...
