A gateway may discard Internet datagrams if it does not have the buffer space needed to queue the datagrams for output to the next network on the route to the destination network. If a gateway discards a datagram, it may send a source quench message to the Internet source host of the datagram. A destination host may also send a source quench message if datagrams arrive too fast to be processed....

This report presents a practical implementation of a novel two-phase, three-message strategy for half-duplex relaying, which consists of superposition coding and interference-aware cancellation decoding. As opposed to past works, the channel model has a direct link between the source and the destination, through which the source continuously sends information to the destination at a rate close ...

A critical component of any parallel processing system is the interconnection network that provides communications among the system's processors and memories. The data manipulator (gamma) network family is an important class of multistage in-terconnection networks that is being studied by various researchers. One interesting property of the data manipulator network family is the existence of mu...

In this paper, we investigate the problem of communication over cognitive interference channel (CIC) with partially cooperating (PC) destinations (CIC-PC). This channel consists of two source nodes communicating two independent messages to their corresponding destination nodes. One of the sources, referred to as the cognitive source, has a noncausal knowledge of the message of the other source,...

In this study, we examined origin, destination, and community effects on first- and second-generation immigrants' health in Europe. We used information from the European Social Surveys (2002–2008) on 19,210 immigrants from 123 countries of origin, living in 31 European countries. Cross-classified multilevel regression analyses reveal that political suppression in the origin country and living i...

background: the need for better healthcare has grown significantly in recent years. in addition, the rising healthcare costs in the u.s. and in many european countries have forced many patients to seek medical treatment abroad, which has created the demand for medical tourism. with little yet known as to the perception of a medical tourist's destination selection, this study aims to explore med...
