Periodic sticking motions can occur in vibro-impact systems for certain parameter ranges. When the coefficient of restitution is low (or zero), the range of periodic sticking motions can become large. In this work the dynamics of periodic sticking orbits with both zero and non-zero coefficient of restitution are considered. The dynamics of the periodic orbit is simulated as the forcing frequenc...

In the present study a Friction-Driven oscillator is investigated analytically using perturbation method and numerically with Runge–Kutta’s integration procedure. The analytical method is also used to investigate damping performance of a single-particleimpact damper on amplitude and frequency of system over a wide range of particle-to-structure mass ratios, clearance, and coefficients of restit...

cet article s’intéresse aux titres littéraires et aux problèmes de leur traduction.  les stratégies de traduction sont plus nombreuses que ce que l’on croit; mais l’objectif de toute traduction est la restitution du sens. or à travers cette recherche, nous avons tenté de démontrer que la restitution du sens du titre original ne suffit absolument pas. en effet, le travail sur les mots d’un titre...

BACKGROUND Enhanced sympathetic activity facilitates complex ventricular arrhythmias and fibrillation. The restitution properties of action potential duration (APD) are important determinants of electrical stability in the myocardium. Steepening of the slope of APD restitution has been shown to promote wave break and ventricular fibrillation. The effect of adrenergic stimulation on APD restitut...

Integrity of colon epithelium is of crucial importance and, as small defects occur constantly, rapid repair (restitution) is essential. To investigate the mechanism of restitution, single-cell lesions were induced in mouse colonic surface epithelia by iontophoretic injection of Ca2+. Closure of the resulting defects was monitored using confocal laser scanning microscopy (CLSM), and functional s...

Mandatory statutes do not always produce change, but a 1995 Pennsylvania statutory change making restitution mandatory dramatically increased the proportion of cases in which restitution was imposed. There are three possible reasons for this generally successful implementation: (a) judges agreed with the victim-centered goals of the statute, (b) there were mechanisms in place to implement the g...

Early rapid mucosal restitution occurs as a consequence of epithelial cell migration to reseal superficial wounds, a process independent of cell proliferation. Our previous studies revealed that the canonical transient receptor potential-1 (TRPC1) functions as a store-operated Ca(2+) channel (SOCs) in intestinal epithelial cells (IECs) and regulates epithelial restitution after wounding, but th...
