Excludable and congestible shared goods club goods (e.g., internet access facilities) are more prevalent than Samuelsonian public goods. We construct an example to show that the optimal second-best provision level of a club good might exceed its ̄rst-best level. This is unlike the usual presumption with pure public goods. We argue that our ̄nding arises because user charges can be levied on clu...

This paper introduce the forward linear prediction for equalization of OFDM systems in space time channels. We shown by simulations that linear prediction structure have better performance that MERRY algorithm both to exploit space time diversity than tracking channel variations along of time. Keywords—OFDM, Blind Channel Shortening, Linear Multichannel Prediction, SIMO, MERRY, Second Order Sta...

This paper presents a multi-objective model for location-transportation problem under uncertainty that has been developed to respond to crisis. In the proposed model, humanitarian aid distribution centers (HADC), the number and location of them, the amount of relief goods stored in distribution centers, the amount of relief goods sent to the disaster zone, the number of injured people transferr...

Epicardial cells are more susceptible to the electrophysiological effects of ischemia than are endocardial cells. To explore the ionic basis for the differential electrophysiological responses to ischemia at the two sites, we used patch-clamp techniques to study the effects of ATP depletion on action potential duration and the ability of ATP-regulated K+ channels in single cells isolated from f...
