Abstract:
Disclosed is a depolymerized glycosaminoglycan from Thelenota ananas (dTHG), weight average molecular weight of which is about 8000˜20000 Da, and monosaccharide components of which are acetylgalactosamine (GalNAc), glucuronic acid (GlcUA), fucose (Fuc) or their sulfates (expressed as —OSO3−), in which molar ratio of GalNAc:GlcUA:Fuc:—OSO3− is about 1:(1±0.3):(1±0.3):(3.5±0.5). Said dTHG is a potent endogenous inhibitor of factor X, which has good anticoagulant and antithrombotic activity, and can be used for the prevention and/or treatment of thrombotic diseases. Also provided is a method for preparing said dTHG, which comprises steps of 1) extracting and obtaining fucosylated glycosaminoglycan (THG) from the body wall of Thelenota ananas; 2) depolymerizing THG to obtain dTHG by method of peroxide depolymerization or method of peroxide depolymerization catalyzed by catalyst of the fourth period transition metal ions; 3) removing impurities with lower and/or higher molecular weight in dTHG.
Abstract:
A vector processor is provided having an instruction set with a vector convolution function. The disclosed vector processor performs a convolution function between an input signal and a filter impulse response by obtaining a vector comprised of at least N1+N2-1 input samples; obtaining N2 time shifted versions of the vector (including a zero shifted version), wherein each time shifted version comprises Ni samples; and performing a weighted sum of the time shifted versions of the vector by a vector of Ni coefficients; and producing an output vector comprising one output value for each of the weighted sums. The vector processor performs the method, for example, in response to one or more vector convolution software instructions having a vector input. The vector can comprise a plurality of real or complex input samples and the filter impulse response can be expressed using a plurality of coefficients that are real or complex.

Abstract:
A semiconductor device having light-emitting diodes (LEDs) formed on a concave textured substrate is provided. A substrate is patterned and etched to form recesses. A separation layer is formed along the bottom of the recesses. An LED structure is formed along the sidewalls and, optionally, along the surface of the substrate between adjacent recesses. In these embodiments, the surface area of the LED structure is increased as compared to a planar surface. In another embodiment, the LED structure is formed within the recesses such that the bottom contact layer is non-conformal to the topology of the recesses. In these embodiments, the recesses in a silicon substrate result in a cubic structure in the bottom contact layer, such as an n-GaN layer, which has a non-polar characteristic and exhibits higher external quantum efficiency.
