Abstract This paper deals with an interesting facility location problem known as the bi-objective p -Median and -Dispersion ( BpMD problem). The seeks to locate facilities service a set of n demand points, goal is minimize total distance between points and, simultaneously, maximize minimum all pairs hosted facilities. addressed novel path relinking approach, called reactive relinking, which hyb...
Left stellate or right stellate ganglion stimulation (LGSG or RSGS, respectively) is associated with ventricular tachyarrhythmias; however, the electrophysiological mechanisms remain unclear. We assessed 1) regional dispersion of myocardial repolarization during RSGS and LSGS and 2) regional electrophysiological mechanisms underlying T-wave changes, including T-peak to T-end (Tp-e) interval, wh...
The underlying mechanism of the low-frequency dielectric dispersion, called the alpha dispersion, of osmotically lysed erythrocytes (erythrocyte ghosts) has remained open since its finding [H. P. Schwan and E. L. Carstensen, Science 125, 985 (1957)]. The alpha dispersion is peculiar to erythrocyte ghosts and has never been observed for intact erythrocytes. Numerical calculation based on interfa...
AIMS This study was designed to test the hypothesis that acute psychological stress is capable of inducing an increase in the dispersion of repolarization in patients with underlying coronary artery disease. METHODS AND RESULTS Twenty four patients undergoing elective coronary angiography were studied, 17 with significant coronary artery disease and seven with normal coronary arteries. Follow...
In this article we are concerned with the instability and stability properties of traveling wave solutions of the double dispersion equation utt − uxx + auxxxx − buxxtt = −(|u|u)xx for p > 1, a ≥ b > 0. The main characteristic of this equation is the existence of two sources of dispersion, characterized by the terms uxxxx and uxxtt. We obtain an explicit condition in terms of a, b and p on wave...
