Clustering is an efficient approach in a wireless sensor network (WSN) to reduce the energy consumption of nodes and to extend the lifetime of the network. Unfortunately, this approach requires that all cluster heads (CHs) transmit their data to the base station (BS), which gives rise to the long distance communications problem, and in multi-hop routing, the CHs near the BS have to forward data...

BACKGROUND Evidence about a possible causal relationship between non-specific physical symptoms (NSPS) and exposure to electromagnetic fields (EMF) emitted by sources such as mobile phone base stations (BS) and powerlines is insufficient. So far little epidemiological research has been published on the contribution of psychological components to the occurrence of EMF-related NSPS. The prior obj...

Suggestions for efficiently determining the lifetimes and mass difference of the light and heavy Bs mesons (B L s , B H s ) from Bs → J/ψφ,D∗+ s D∗− s decays are given. Using appropriate weighting functions for the angular distributions of the decay products (moment analysis), one can extract (ΓH ,ΓL,∆m)Bs . Such a moment analysis allows the determination of the relative magnitudes and phases o...

Objectives—We performed a detailed kinetic analysis in a rat balloon injury model to clarify the essential roles of v 3 integrin and endothelial cell (EC) regeneration in neointima formation. Using this model, we evaluated the antistenotic effect of Dainippon compound BS-1417, a novel v 3 integrin antagonist. Methods and Results—Kinetic analysis using RT-PCR showed that v 3 integrin-related gen...

Jack M. Holtzman Qualcomm, Inc. 5775 Morehouse Drive, San Diego, Ca 92121-1714 [email protected] It was previously shown (under simplifying assumptions) that this algorithm gives equal power and time to users who only differ in the distance from the BS, their fading characteristics being the same. We give here a more general result for two classes of users with different fading characterist...

This paper considers an uplink multiuser massive multiple-input multiple-output (MIMO) system with lowresolution analog-to-digital converters (ADCs), in which K users with a single-antenna communicate with one base station (BS) with Nr antennas. In this system, we present a novel multiuser MIMO detection framework that is inspired by coding theory. The key idea of the proposed framework is to c...

We present a complete calculation of the Leading Order QCD corrections to the quark level decay amplitude for b → sγγ and study their relevance for both the inclusive branching ratio BR(B → Xsγγ) and for the exclusive decay channel Bs → γγ. In addition to the uncertainties in the short distance calculation, due to the choice of the renormalization scale, an appreciable uncertainty in both Bs → ...

Spatial distributions of other cell interference (OCIF) and interference to own-cell power ratio (IOPR) with reference to the distance between a mobile and its serving base station (BS) are modeled for the down-link reception of cellular systems based on the best-cell configuration instead of the nearest-cell configuration. This enables a more realistic evaluation of two competing objectives in...
