With the development of deregulated power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benefi...

The Mass Transit Railway (MTR) serves as the backbone of Hong Kong public transportation network and continues to be expanded in phases. Nevertheless, occasional but severe disruptions have raised concerns about whether proposed MTR expansions will benefit system resilience. To assess value each stage expansion, it is key identify distributive effects new metro lines on both accessibility This ...

introduction: electrophysiological studies have demonstrated a relationship between aging and atrioventricular (av) nodal conduction and refractoriness. the aim of the present study was to determine the effects of nodal aging on dynamic av nodal field potential recording during atrial fibrillation (af) in rabbit. methods: two groups of male new zealand rabbits (neonatal 2-week-olds and adult 12...

BACKGROUND/AIMS The previous study in our lab showed that Nodal molecule on bronchial epithelial cells (BECs) was modulated by all kinds of lung microbes. The present study was designed to determine the effects of Nodal on proliferation of BECs and BECs-induced differentiation of T-helper (Th) cells. The epigenetic mechanisms of Nodal expression following treatments of different lung microbes w...

The chronotropic responses to repetitive bursts of vagal stimulation were determined in open-chest, anesthetized dogs. Either 5 or 10 electrical pulses were included in each stimulus burst, and the interpulse interval (deltat) was varied over the range of 5 to 150 msec. As the frequency of the stimulus bursts was progressively changed, the sinoatrial (SA) nodal pacemaker cells became synchroniz...
