The centroidal Voronoi tessellation (CVT) has found versatile applications in geometric modeling, computer graphics, and visualization, etc. In this paper, we first extend the concept of CVT from Euclidean space to spherical space and hyperbolic space, and then combine all of them into a unified framework – the CVT in universal covering space. The novel spherical and hyperbolic CVT energy funct...

PURPOSE To explore the effectiveness of canine visitation therapy (CVT) in pediatric pain management in a tertiary care children's hospital, a descriptive pilot study was conducted. METHOD A convenience sample of 25 English-speaking children ages 5 to 18 years who underwent surgery and experienced acute postoperative pain participated in a standard, one-time CVT intervention. Each child compl...

‘Non-excludability’ of skills is suspected to give rise to poaching externalities and cause under-investment in training. To substantiate this hypothesis, the paper at hand investigates the relationship between labor turnover and firms’ dedication to continuing vocational training (CVT) exploiting novel survey data on firms in Germany (BIBB-FluCT data, N = 1.238). Regression analyses of these d...

CVT-E002, a proprietary extract from North American ginseng (Panax quinquefolium) showed immunomodulating activity. Cytochrome P450 (CYP), UDP-glucuronosyl transferase (UGT), and glutathione S-transferase (GST) are important drug-metabolizing enzymes. Modulation of drugmetabolizing enzymes is a main cause of drug interactions. To assess the possible metabolism-based drug interaction of CVT-E002...

Cerebral venous thrombosis (CVT) is an uncommon disease that mainly affects subjects younger than 40 years of age, patients with thrombophilia, and women who are pregnant or receiving hormonal contraceptives. The annual incidence is estimated to be 3 to 4 cases per million, which increases to 12 cases per 100 000 deliveries during the peripartum period. Mortality and recurrence rates are lower ...

BACKGROUND The parasympathetic nervous system has been implicated in the pathogenesis of a number of gastrointestinal disorders including irritable bowel syndrome. Within the field, cardiometric parameters of parasympathetic/vagal tone are most commonly derived from time, or frequency, domain analysis of heart rate variability (HRV), yet it has limited temporal resolution. Cardiac vagal tone (C...

There is substantial evidence in the literature that elevated plasma free fatty acids (FFA) play a role in the pathogenesis of type 2 diabetes. CVT-3619 is a selective partial A(1) adenosine receptor agonist that inhibits lipolysis and lowers circulating FFA. The present study was undertaken to determine the effect of CVT-3619 on insulin resistance induced by high-fat (HF) diet in rodents. HF d...

In the present study, the aim is to optimize full and half toroidal continuously variable transmission (CVT) in order to minimize the vehicle fuel consumption (FC) in ECE driving cycle. First, the model of both CVTs’ efficiency is presented. The control strategy of CVTs speed ratio based on minimizing the vehicle FC is introduced, and the algorithm of calculating the vehicle FC is shown. Afterw...
