Parasympathetic regulation of heart rate through the vagus nerve—often measured as resting respiratory sinus arrhythmia or cardiac vagal tone (CVT)—is a key biological correlate of psychological well-being. However, recent theorizing has suggested that many biological and psychological processes can become maladaptive when they reach extreme levels. This raises the possibility that CVT might no...

Aminopeptidase I (API) is imported into the yeast vacuole/lysosome by a constitutive non-classical vesicular transport mechanism, the cytoplasm to vacuole targeting (Cvt) pathway. Newly synthesized precursor API is sequestered in double-membrane cytoplasmic Cvt vesicles. The Cvt vesicles fuse with the vacuole, releasing single-membrane Cvt bodies containing proAPI into the vacuolar lumen, and m...

Revolute-jointed cobots depend on continuously variable transmissions (CVTs). CVTs constrain the speed ratio between two shafts to a particular value within a continuous range. The spherical CVT is well suited to cobots, but like other point contact transmissions, achieving good performance is challenging. We have studied the contact mechanics of the spherical CVT under certain simplifying assu...

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...

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 ...

The Center for Transportation Research (CTR) Vehicle Systems team modified a Nissan CK-2 Continuously Variable Transmission (CVT) for a diesel hybrid powertrain application. Mechanical and electrical modifications were made to the CVT, both internal and external to the transmission. The goal of this experiment was to investigate and demonstrate the potential of CVT for diesel engines hybrid ele...

Cerebral venous thrombosis (CVT) is a clinical condition which is caused by the partial or complete occlusion of the dural sinuses and cerebral veins. Cases of associated CVT and multiple sclerosis (MS) have been reported and CVT development has been attributed to the previous lumbar puncture (LP) in majority of these cases. We report a case of 32-year-old woman with no previous history of rece...

This article reports on the design, analysis and control of a new type of wheeled mobile robot based on a nonholonomic spherical continuously variable transmission (S-CVT). Our S-CVT based mobile robot is designed to increase the run time (i.e., the length of time in which the robot can be operated), and to achieve full planar accessibility with the design of a novel pivoting device that takes ...

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...

background: we report a case series of cerebral vein thrombosis (cvt) in women who used oral contraceptive pill (ocp) in the muslims ramadan and fasting month. methods: this study was a retrospective case series of 9 patients with diagnosis of cvt, who admitted in the neurology ward of tohid hospital of sanandaj, iran, in july-august 2014-2015. results: patients had no history of thrombosis bef...
