compactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
15 صفحه اولBaroreflex Sensitivity Estimation by the Transfer Function Method Revised: Effect of Changing the Coherence Criterion
In this study we appraised three new criteria for the computation of baroreflex sensitivity (BRS) using the transfer function magnitude (TFM) method, with the aim of overcoming the conventional requirement of a coherence ≥ 0.5 between arterial pressure and RR interval time series. Measurements were carried out in a sample of 44 post-myocardial infarction patients at risk of malignant arrhythmia...
متن کاملAssessing baroreflex sensitivity by the transfer function method: what are we really measuring?
BY GOVERNING THE AUTONOMIC OUTFLOW to the heart and blood vessels, arterial baroreceptors play a central role in controlling short-term blood pressure responses to the hemodynamic perturbations continuously occurring in daily life. Abnormalities in baroreflex function are thought to play an important pathogenic role in the setting of cardiovascular disease, by reducing the restraining influence...
متن کاملElectronic Transmission Wave Function of Disordered Graphene by Direct Method and Green's Function Method
We describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. We present a new method for computing, electronic transport wave function and Greens function of the disordered Graphene. In this method, based on the small rectangular approximation, break up the potential barriers in to small parts. Then using the f...
متن کاملAnalysis of Baroreflex Function by Means of Mathematical Model.
Re-evaluation of all functions of baroreflex by means of a simple mathematical model of circulation was the aim of the present study. The following states are modelled: 1. Rest. 2. Immediately after baroreceptor denervation. 3. Several days after denervation. 4. Physical exercise before denervation. 5. Physical exercise several days after denervation. Despite the same cardiac contractility and ...
