  • Publication number: 20150044699
    Abstract: The present invention relates to a Vibrio harveyi-specific binding Dscam of shrimps, a method for identification thereof and a use thereof. Primarily, Dscam cDNAs are prepared from V. harveyi-challenged shrimps. A database is established with various Dscam isoforms therein by means of numerous cloning and sequencing. After a phylogenetic analysis, a plurality of candidate Dscam isoforms is selected. Each recombinant protein of candidate Dscam isoforms is expressed through an expression system. Finally, the binding affinity between V. harveyi and each recombinant protein of candidate Dscam isoforms is measured to further selection of a V. harveyi-specific binding Dscam and the amino acid sequence thereof. Accordingly, the Dscam can be specifically binding to V. harveyi for eliminating or reducing V. harveyi.

  • Patent number: 8933726
    Abstract: A dynamic voltage scaling system having time borrowing and local boosting capability, including: a time borrowing circuit and a local boost circuit. The time borrowing circuit connected electrically between a primary stage logic circuit and a secondary stage logic circuit is activated by an all-domain clock signal, and then generates an output data to the secondary stage logic circuit based on input data to the primary stage logic circuit. The local boost circuit is connected to a low working voltage line, when input data of the time borrowing circuit lags behind a positive level of said all-domain clock signal, the time borrowing circuit delays fetching data by a flip flop and changes state to produce a warning signal, so that the local boost circuit disconnects its connection with said low working voltage line, and is connected electrically to a high working voltage line.

  • Publication number: 20150012901
    Abstract: A fixed-outline floorplanning approach for mixed-size modules is disclosed. Firstly, evenly distribute mixed-size circuit modules to whole chip area based on different requirements such as wire-length, routability, or thermal in the global distribution stage. To maintain the global distribution result and satisfy the fixed-outline constraint, generate a slicing tree by recursively applying partition algorithm to divide modules distributed in a given region into several sub-regions. Then, to remove overlap between circuit modules and find a best solution, use bottom-up shape curve merging and top-down back tracing procedure to generate a slicing tree. The shape curve for each leaf in the tree is built first by enumerated packing. Then, the curves in the tree are merged iteratively from bottom to top, and feasible solutions in the shape curve of the root node are identified according to the fixed-outline constraint. Finally, the best solution is determined by a top-down back tracing procedure.
