Beam intensity and spectral coherence of Hermite-cosine-Gaussian rectangular multi-Gaussian correlated Schell-model beam in oceanic turbulence.

The beam spreading and evolution behavior of a partially coherent, Hermite-cosine-Gaussian (HcosG) rectangular multi-Gaussian correlated Schell-model beam propagating in oceanic turbulence is studied. Analytical expressions for the cross-spectral density function, as well as the root mean square (rms) beam width and the spectral degree of coherence, are derived based on the extended Huygens-Fresnel principle. The HcosG rectangular multi-Gaussian correlated Schell-model beam exhibits a multi-lobe pattern at short propagation distances.

Association between K469E polymorphism of ICAM-1 gene and susceptibility of ischemic stroke: An updated meta-analysis.

Background: The intercellular adhesion molecule-1 (ICAM-1)/leukocyte function associated antigen-1 (LFA-1) adhesion system regulates leukocyte interactions, migration, and adhesion, and appears to play an important role in atherosclerosis and thrombosis. Therefore, single nucleotide polymorphisms (SNPs) of the ICAM-1 gene may strongly influence the expression and biological activity of ICAM-1 and play a potentially important role in the pathogenesis of ischemic stroke. In the current meta-analysis, we investigated the relationship between the ICAM-1 gene K469E SNP and the risk of ischemic stroke.
