PURPOSE Identification of transcription factors that regulate the transcription of the vascular endothelial growth factor (VEGF) gene may facilitate understanding of the etiology and progression of ocular neovascular diseases. The purpose of this study was to determine whether transcriptional enhancer factor 1-related (RTEF-1) was present within ocular vascular endothelial cells and whether it ...

In this study, we have theoretically investigated the effect of electron stopper layer on internal temperature distribution of high performance vertical cavity surface-emitting laser emitting at 1305 nm. Simulation software PICS3D, which self-consistently combines the 3D simulation of carrier transport, self-heating, gain computation and wave-guiding, was used. Simulation results show that chan...

The elevated levels of plasma renin activity (PRA) in stroke-prone SHR rats (SHRSP) at several months of age were reported by Matsunaga et al (Jap Circulat J 39: 1305, 1975) and Morita and Okamoto (Jap Heart J 18: 573, 1977). Matsunaga et al (Jap Circulat J 40: 889, 1976) divided SHRSP into 2 groups on the basis of water turnover: one had significantly higher water intake and urine volume than ...

Uncertainty is an inherent aspect of the open-pit mine production scheduling problem (MPSP); however, little is reported in the literature about solution methods for the stochastic versions of the problem. In this paper, two variants of a variable neighbourhood descent algorithm are proposed for solving the MPSP with metal uncertainty. The proposed methods are tested and compared on actual larg...

Recently, a parallel hash function based on chaotic maps with changeable parameters was proposed by Li et al (2011, pp.1305-1312). In this paper, the security of it is analyzed and the weakness of the architecture is pointed out. It is found that the main limitations are the error using of floor, round and exclusive OR operations in the algorithm. In order to counterstrike these, some improveme...
