    摘要： Si/SiO2 core/shell nanostructures with sizes below 30 nm as trapping points in UV curable hybrid organic-inorganic gate dielectrics are presented in order to investigate printable nano floating gate transistors. Not only does the novelty of this invention comes from fabricating high-quality hybrid organic/inorganic gate dielectric layer by Sol-Gel process at low temperature but also incorporating the monolayer of high-density of Si nanoparticles (NPs) without obvious interface defects and keeping the quality of dielectric layers. Fixed-charge trapping defects are successfully removed from hybrid dielectrics by UV curing together with low temperature thermal curing and mobile charges solely related to Si/SiO2 core/shell nanostructures on charge trapping layer clearly demonstrate memory effects on printable device. Thin/uniform SiO2 shell on each Si NP functions as tunneling layer of flash memory devices, significantly simplifying the fabrication of printable nano floating gate memory device.

    摘要： The present invention provides a site-specific pegylated arginase conjugate and method for producing thereof. The site-specific pegylated arginase is homogeneous in molecular weight and shows therapeutic effect for treating cancers and viral infections. The method for producing the arginase conjugate comprises genetically modifying the gene encoding an arginase so that the PEG moiety can be attached to the enzyme at a predetermined, specific intended sites. This is achieved by removing the PEG-attaching amino acid residue(s) at undesirable site(s) while keeping or adding cysteine(s) at the desirable site(s) of the enzyme. Two exemplary embodiments of the pegylated arginase conjugate are directed to human arginase I (HAI) where a polyethylene glycol (PEG) moiety is site-specific covalently bonded to Cys45 of the enzyme and Bacillus caldovelox arginase (BCA) where a polyethylene glycol (PEG) moiety is site-specific covalently bonded to Cys161 of the enzyme.

    摘要： The present invention is to provide a method and system for determining true touch points on input touch panel. Two optical sensing module pairs are used to determine two groups of possible touch regions, further with overlap checking with virtual shadow regions to find out potential touch points. Occlusion checking is implemented to acquire true touch points from the potential touch points. The method of the present invention is capable of acquiring true touch points in a fast and reliable way. Furthermore, an interactive input system of the present invention comprises optical sensing modules having their corresponding optical emitters with different wavelengths, and light filters with peak transmission at different wavelengths to avoid from interference effect and over-exposed signal during signal detection by the optical sensing modules.

    摘要： A method for scheduling a random-access communication system having high-priority (HP) and low-priority (LP) nodes is provided, where the scheduling is configured such that the system provides an absolute throughput guarantee for the HP nodes, and a proportional throughput guarantee for the LP nodes. The method is based on obtaining a length of a contention window assigned to an individual node, which is either a HP or a LP node, from a per-slot attempt rate of this individual node. In particular, the attempt rate of each individual node is determined by an algorithm configured such that a resultant sum of the per-slot attempt rates of all the individual nodes is a fixed value independent of the number of the individual nodes. By this scheduling method, the maximum system throughput is approached. The method can be advantageously used in a wireless local area network (WLAN).
