This study aimed at testing the hypothesis that differences in neural activation strategy during submaximal but not maximal plantarflexions exist between young and older men. Eleven young men (YM, 26 ± 4 years) and thirteen old men (OM, 76 ± 3 years) volunteered for the investigation. Maximal voluntary torque (MVT) was 38.2%, lower (p < 0.001) in OM than in YM, while voluntary activation was eq...

Mississippi Valley-type (MVT) ore deposits arc epigenetic carbonate-hosted Pb-Zn deposits that contain galena, sphalerite, fluorite, bar&e, dolomite, calcite, and quartz. Although they are thought to form from basinal brines, their exact origins are still unclear, partly because of the scarcity of reliable geochronological data. Rb-Sr dating of sphalerites has recently been shown to be a promis...

ICDs rely upon programmable rate cutoffs to direct therapy delivery. Studies showing reduced mortality when high voltage (HVT) is avoided have led programming that promotes longer detection times and higher rates. However, such can also result in delayed for hemodynamically compromising polymorphic VT (PVT) or ventricular fibrillation (VF). We aim characterize tachyarrhythmia (VTA) features dev...

The Marginal Value Theorem (MVT) is a cornerstone of biological theory. It connects the quality and distribution of patches in a fragmented habitat to the optimal time an individual should spend exploiting them, and thus its optimal rate of movement. However, predictions regarding how habitat alterations should impact optimal strategies have remained elusive, with heavy reliance on graphical ar...

The influence of contraction type on the human ability to use the torque capacity of skeletal muscle during explosive efforts has not been documented. Fourteen male participants completed explosive voluntary contractions of the knee extensors in four separate conditions: concentric (CON) and eccentric (ECC); and isometric at two knee angles (101°, ISO101 and 155°, ISO155). In each condition, to...

The dissipation process of GRB prompt emission is still unknown. Study temporal variability may provide a unique way to discriminate the imprint inner engine activity from geometry and propagation related effects. We define minimum timescale (MVT) as shortest duration individual pulses that shape light curve for sample GRBs test correlations with peak luminosity, Lorentz factor, jet opening ang...

We aimed to study patients with splanchnic vein thrombosis (SVT) and cerebral vein thrombosis (CVT) searching for JAK2 mutations. We evaluated 14 patients (median age: 41.5 years) with portal vein thrombosis (PVT) = 7; mesenteric vein thrombosis (MVT) = 3; and CVT = 4. JAK2 V617F was assessed by allele specific PCR of peripheral blood DNA. In addition, DNA was sequenced for other JAK2 mutations...
