We present results of light scattering properties for ensembles of randomly oriented, coated spheroidal particles with an equivalent-volume size parameter kr %2 "8 and axial ratios e"0.6,1, and 1/0.6. MuK ller matrix elements F ij (h) have been calculated using Waterman's 1-matrix approach, as modi"ed by Peterson and StroK m for inhomogeneous particles, together with Mishchenko's orientation av...

The effect of noise variations on two of the short period seismic discriminants, spectral ratio and log-likelihood ratio is studied. The mean square errors of two different estimators of these two discriminants are evaluated and some theoretical and experimental results for two seismic signals in seismic noise are presented.

We present a complete sequence homology search server based on the hybrid CPU/GPU implementation of the Smith Waterman algorithm for sequence alignment. We discuss system architecture, division of the tasks between CPU and GPU in the hybrid design, the scalability issues and hardware requirements. The performance of the server is compared with the state-ofthe-art sequence analysis servers. Bioi...

We establish L2 → Lq mapping bounds for unit-width spectral projectors associated to elliptic operators with Cs coefficients, in the case 1 ≤ s ≤ 2. Examples of Smith-Sogge [6] show that these bounds are best possible for q less than the critical index. We also show that L∞ bounds hold with the same exponent as in the case of smooth coefficients.

Geometric inequalities for simplices which are the simplest and the most useful polytopes have been a very attractive subject for a long time. Mitrinovic, Pecaric, Volenec [9], Ali [1], Gerber [4], Petty, Waterman [11] and other authors [7,8] have obtained a great number of elegant results. Specially, the quantity relations involving two simplices have been studied extensively. The well-known N...

In these notes, we review recent results concerning the Lp norm bounds for spectral clusters on compact manifolds. The type of estimates we consider were first established by Sogge [15] in the case of smooth metrics. Recent results of ours in [10] establish the same estimates under the assumption that the metric is C1,1. It is known by examples of Smith-Sogge [12] that such estimates fail for C...

Background: Evidence suggests an inverse relationship between soy protein intake and serum concentrations of male sex hormones. Anecdotal evidence indicates that these alterations in serum sex hormones may attenuate changes in lean body mass following resistance training. However, little empirical data exists regarding the effects of soy and milk-based proteins on circulating androgens and exer...

GPU parallelism for real applications can achieve enormous performance gain. CPU-GPU Communication is one of the major bottlenecks that limit this performance gain. Among several libraries developed so far to optimize this communication, DyManD (Dynamically Managed Data) provides better communication optimization strategies and achieves better performance on a single GPU. SmithWaterman is a wel...
