The third-generation universal mobile telecommunications system (UMTS) uses direct-sequence code division multiple access (DS-CDMA) to transmit data. DS-CDMA is well suited to transmit data over the multipath fading channel. The high signal bandwidth for the WCDMA system (5 MHz) allows the received signal to be split into distinct multipaths with high resolution. For the first generation of UMT...

The high expectations of performance and availability for wireless mobile systems has presented great challenges in the modelling and design of fault tolerant wireless systems. The proper modelling methodology to study the degradation of such systems is so-called performability modelling. In this paper, we give overview of approaches for the construction and the solution of performability model...

This paper evaluates the joint impact of exclusive channels and revenue sharing on suppliers and retailers in a hybrid duopoly common retailer and exclusive channel model. The model bridges the gap in the literature on hybrid multichannel supply chains with bilateral complementary products and services with/without revenue sharing. The analysis indicates that, without revenue sharing, the suppl...

Recently, a variety of new measures of quantum Rényi mutual information and quantum Rényi conditional entropy have been proposed, and some of their mathematical properties explored. Here, we show that the Rényi mutual information attains operational meaning in the context of composite hypothesis testing, when the null hypothesis is a fixed bipartite state and the alternate hypothesis consists o...

We investigate the composite effects of multipacket reception (MPR) and relaying capability in affecting the stability region of a wireless network. With a general MPR channel, a trade-off arises as to whether to activate the relay simultaneously with the source so that both transmissions might be successful, or to let the relay remain silent to overhear the source’s transmission and then activ...

We perform a systematic analysis of the mass and strong decays $\mathrm{\ensuremath{\Omega}}(2012)$ resonance in coupled-channel approach bare three-quark state composite meson-baryon state. Besides coupling ${\mathrm{\ensuremath{\Xi}}}^{*}\overline{K}$ channel, effective interactions are also included. find pole with 2008 MeV by solving Bethe-Salpeter equation. The calculated decay widths its ...

High specific strength of the material is critical for many structural applications in automotive and aerospace design. Among many other approaches for strengthening the materials, development of superfine and nano grained microstructure is becoming popular. Different techniques for producing ultra-fine-grained (UFG) materials have been introduced especially in the last decade. The advantages o...

introduction: we have recently reported the presence of two potassium currents with 598 and 368 ps conductance in the rough endoplasmic reticulum (rer) membrane. the 598 ps channel was voltage dependent and atp sensitive. however, the 368 ps channel was rarely observed and its identity remained obscure. since cationic channels in intracellular organelles such as mitochondria and rer play import...
