A Mobile Station (MS)-controlled fast and simple scheme of handover (HO) in Mobile WiMAX network has been described. An MS can roughly estimate its present distance from any neighbouring Base Stations (BS) using the Received Signal Strength (RSS) and an appropriate pathloss formula. From the Mobile Neighbor Advertisement (MOB_NBR-ADV) broadcasts, the MS periodically monitors the RSS of its Serv...

In this article, we calculate the masses and residues of the heavy baryons Ω∗c(css) and Ω ∗ b(bss) with spin-parity 3 2 + with the QCD sum rules. The numerical values are compatible with experimental data and other theoretical estimations. PACS number: 14.20.Lq, 14.20.Mr

A first step to perform a competition of methods for source separation is the development of a testsuite that supports the development and evaluation of blind source separation (BSS) algorithms in a highly automated way. The concept of our testsuite is presented and it is shown how the testsuite can be used to apply BSS-algorithms to four standard sub-problems. To compare the performance of arb...

The core of the Galactic Globular ClusterM 3 (NGC 5272) has been observed with the WFPC2 through the filters F255W , F336W , F555W , and F814W . Using these observations along with a thorough reanalysis of earlier catalogs, we have produced a catalog of blue straggler stars (BSS) spanning the cluster. Earlier studies and the fainter part of our sample suffer severe selection biases. Our analysi...

Bernard-Soulier syndrome (BSS) is an extremely rare hereditary bleeding disorder, caused by mutations occurring in the Glycoprotein (GP) Ibalpha, GPIbbeta and GP9 genes that encode for the corresponding subunits of platelet GPIb-V-IX adhesion receptor complex. BSS has been reported in many populations, mostly behaving in an autosomal-recessive manner.While the great majority of BSS mutations ar...

BACKGROUND Intestinal bile salts (BSs) may be implicated in NEC development. We hypothesized that fecal BS levels are higher in preterm infants at risk for NEC. METHODS We compared the composition and concentration of fecal BSs in ten preterm infants who developed NEC (Bell's Stage ≥ II) with twenty matched control infants without NEC. Conjugated and unconjugated fecal BSs were measured after...

Blind source separation (BSS) is widely used to analyse brain recordings like the magnetoencephalogram (MEG). However, few studies have compared different BSS decompositions of real brain data. Those comparisons were usually limited to specific applications. Therefore, we aimed at studying the consistency (i.e., similarity) of the decompositions estimated for real MEGs from 26 subjects using fi...

Frequency domain Blind Source Separation (BSS) is shown to be equivalent to two sets of frequency domain adaptive microphone arrays, i.e., Adaptive Null Beamformers (ANB). The minimization of the off-diagonal components in the BSS update equation can be viewed as the minimization of the mean square error in the ANB. The unmixing matrix of the BSS and the filter coefficients of the ANB converge ...

The realization of new cellular networks needs the mobile phone operator to choose optimal location for Base Stations (BSs) placement to reach the wider coverage of a considered territory and the minimum cost of the net itself, that is the minimum number of BSs. In the most situations, and in particular inside the cities, there are a lot of restrictions due to the limited number of available si...
