BACKGROUND Extra-hepatic portal vein obstruction due to portal vein thrombosis (PVT) is an important cause of portal hypertension in several regions including India. The cause of thrombosis in these patients remains unclear. We studied the frequency of mutations in genes for coagulation factors V and II (prothrombin) in 61 Indian patients with PVT and 49 healthy control subjects. METHODS The ...

PURPOSE This study compared the diagnostic accuracy of a general grammaticality measure (i.e., percentage grammatical utterance; PGU) to 2 less comprehensive measures of grammaticality--a measure that excluded utterances without a subject and/or main verb (i.e., percentage sentence point; PSP) and a measure that looked only at verb tense errors (i.e., percentage verb tense usage; PVT)--in diffe...

Finding a representative fluid in a hydrocarbon reservoir is crucial for integrated reservoir management. In this study, a systematic approach for screening and selecting consistent fluid samples in a reservoir was developed. The model integrated quality control (QC) of well conditioning before sampling, QC of PVT data, thermodynamic modeling and compositional gradient within a reservoir. Well ...

Performance variation due to PVT uncertainty has led to an increased interest in adaptive designs. Traditional methods for adaptive design have used so-called canary circuits that mimic the critical-path delay of the actual design [1-4]. However, canary circuits require safety margins for possible mis-tracking and intradie PVT variations. They also have difficulty responding to rapidly changing...

Today virtually every consumer electronics device contains one or more integrated circuits (ICs) that require clock signal generation. This signal must present a certain level of frequency stability even in non-nominal conditions. Ideally, the clock generator block should exhibit a reasonably low frequency deviation when subject to process, voltage, and temperature (PVT) variations, such as cha...

There is ample evidence to suggest that the paraventricular nucleus of the thalamus (PVT) mediates cue-reward learning, especially as it relates to drug-seeking behavior. However, its exact role in these complex processes remains unknown. Here we will present and discuss data from our own laboratory which suggests that the PVT plays a role in multiple forms of stimulus-reward learning, and does...

This paper studies performance of the parallel variable transformation (PVT) algorithm for unconstrained nonlinear optimization through numerical experiments on a Fujitsu VPP500, one of the most up-to-date vector parallel computer. Special attention is paid to a particular form of the PVT algorithm that is regarded as a generalization of the block Jacobi algorithm that allows overlapping of var...

Using a mathematical heat transfer model including anisotropic heat conduction, radiation, and RF heating, we use our software WIAS-HiTNIHS 1 to perform numerical computations of the temperature field in axisymmetric growth apparatus during sublimation growth of silicon carbide (SiC) bulk single crystals by physical vapor transport (PVT) (modified Lely method). As it is not unusual for the ther...
