BACKGROUND Deceleration capacity (DC) is a novel electrocardiography (ECG) parameter characterizing the overall capacity of slowing down the heart rate. The aim of this study was to evaluate clinical and ECG covariates of DC in patients with the first episode of ST-segment elevation myocardial infarction (STEMI) treated with primary angioplasty. METHODS Deceleration capacity, heart rate varia...

PURPOSE A local position measurement (LPM) system can accurately track the distance covered and the average speed of whole-body movements. However, for the quantification of a soccer player's workload, accelerations rather than positions or speeds are essential. The main purpose of the current study was therefore to determine the accuracy of LPM in measuring average and peak accelerations for a...

Stark deceleration has been utilized for slowing and trapping several species of neutral, groundstate polar molecules generated in a supersonic beam expansion. Due to the finite physical dimension of the electrode array and practical limitations of the applicable electric fields, only molecules within a specific range of velocities and positions can be efficiently slowed and trapped. These cons...

Draft: February 1, 2008 In the standard big bang model, the expansion rate of the Universe is predicted to slow down as the Universe evolves. ,2 The deceleration parameter, q0, measures the present deceleration rate. The deceleration causes a deviation from the linear relation between distance and red shift (the Hubble law) at large red shifts. A proposed approach for determining q0 is to measu...
