This paper focuses on the capacity of peer-to-peer relay communications wherein the transmitter are assisted by an arbitrary number of parallel relays, i.e. there is no link and cooperation between the relays themselves. We detail the mathematical model of different relaying strategies including cutset and amplify and forward strategies. The cutset upper bound capacity is presented as a referen...

In the Western world, carcinoma of the pancreas has waxed as gastric cancer has waned, but both remain as major causes of cancer mortality. Carcinoma of the stomach dominates the cancer incidence of Asia and the Soviet Union. Cancers of the liver and oesophagus ravage the continent of Africa in almost epidemic proportions. In spite of the great human need which this problem presents, there are ...

Introduction: Median Nerve (MN) originated from medial and lateral cords of Brachial Plexus can be affected by anatomical variations which may lead to several diagnostic and therapeutic mistakes. This paper aim is to study about MN variations investigated by cadaveric studies. Materials and Methods: This study is based on research in electronic databases. Full text of all relevant papers has b...

For the first time, an assemblage of cryptospores, which includes 10 species belonging to nine genera, from the Upper Ordovicianstrata, is being reported, in Iran. These cryptospore assemblages were recovered from the upper part of Ghelli Formation., from theeastern Alborz Mountain range. These peri-Gondwanan cryptospores have been classified based on their morphology (monad, truedyad, pseudody...

the asmari formation at nil anticline area has been studied in order to determine faunal assemblages, the age and the paleoecology. paleontological and biostratigraphical studies led to the identification of 5 faunal assemblages. as a result, the age of the asmari formation in this section, with 291m thickness, is rupelian/chattian-burdigalian. extension of the large benthic foraminifera sugges...

This paper focuses on the capacity of point-to-point relay communications wherein the transmitter is assisted by an intermediate relay. We detail the mathematical model of cutset and amplify and forward (AF) relaying strategy. We present the upper bound capacity of each relaying strategy from information theory viewpoint and also in networks with Gaussian channels. We exemplify various outer re...

abstract background and aims: one of the complications of breast cancer treatment is ipsilateral upper extremity lymphedema. secondary lymphedema is a chronic condition that leads to loss of function and disorder of quality of life. the aim of this study was to evaluate the effects of complex decongestive physical therapy (cdp) on pain severity and quality of life in patients with secondary upp...
