BACKGROUND Cortical vein thrombosis (CVT) receives little attention in adult patients with cerebral venous sinus thrombosis (CVST). This study aimed to investigate the clinical and radiological features of adult CVST patients with concomitant CVT. METHODS From May 2009 to May 2016, we recruited 44 adult CVST patients (diagnosed within 1 month of onset; 33.8 ± 14.0 years of age, 28 males). CVT...

BACKGROUND Cerebral venous thrombosis (CVT) may lead to serious neurological disorders; however, little is known about the risk factors for recurrent CVT. Our aim was to determine the association between elevated fibrinogen and decreased high-density lipoprotein cholesterol (HDL-C) levels with recurrent CVT. METHODS This retrospective cohort study included participants if they had a first epi...

In this article, we consider a weighted CVT-based reduced-order modelling for Burgers equation. Brief review of the CVT (centroidal Voronoi tessellation) approaches to reduced-order bases are provided. In CVT-reduced order modelling, we start with a snapshot set just as is done in a POD (Proper Orthogonal Decomposition)-based setting. So far, the CVT was researched with uniform density (ρ(y) = ...

The continuously variable transmission (CVT) is a type of transmission that can adopt any arbitrary gear ratio. Whereas typical transmissions utilize toothed gears, the CVT employs a sphere in rolling contact with a set of rollers; loads applied to the CVT are supported across these rolling contacts, resulting in microslips of varying amounts at each contact area. In this paper, we describe the...

Cerebral vein thrombosis (CVT) is uncommon disease and known risk factors of CVT are hereditary thrombophilia, pregnancy, puerperium, and use of oral contraceptives. However, 25% of all cases are considered to be idiopathic. Thyrotoxicosis may be a predisposing factor of CVT due to a hypercoagulable state. Possible associations between thyrotoxicosis and CVT have been described in several case ...

Continuously variable transmission (CVT) is a type of automatic transmission that can change the gear ratio to any arbitrary setting within the limits. The most common type of CVT operates on a pulley system that allows an infinite variability between highest and lowest gears with no discrete steps. However, the current CVT system with hydraulic actuation method suffers from the power loss. It ...

The main purpose of this paper is to explore whether and how the amount of firmsponsored Continuing Vocational Training (CVT) provided in Sweden from 1999 onwards was influenced by institutional conditions. The Swedish labour market is characterised by a relatively large amount of publicly subsidised CVT. How this affects the incidence of firm-sponsored CVT ultimately depends on whether publicl...

Use of automatic transmission systems in motor vehicles in addition to improving the ride comfort is also expected to reduce fuel consumption. The principle of the system Continuously Variable Transmission (CVT) is producing a variation of the ratio of the displacement system (i) as a function of velocity. The main problem is to change the variator CVT push-belt continuously variable from PULLE...

The purpose of this study was to determine the magnitude of vasodilation by CVT-3146 in different vascular beds and to compare it with that by adenosine in conscious dogs. Intravenous bolus injections of CVT-3146 (0.1-2.5 microg/kg) or adenosine (10-250 microg/kg) caused a dose-dependent increase in the coronary blood flow (CBF) and a dose-dependent decrease in the late diastolic coronary resis...

Capacitive Voltage Transformers (CVTs) are common in high-voltage transmission line applications. These same applications require fast, yet secure protection. However, as the requirement for faster protective relays grows, so does the concern over the poor transient response of some CVTs for certain system conditions. Solid-state and microprocessor relays can respond to a CVT transient due to t...
