  • Patent number: 8665988
    Abstract: The present invention provides a device and method for realizing prefix code construction. The device includes a sort indexer, a generator and a sequence regulator. The sort indexer is used to sort a group of received code lengths to obtain a group of sorted code lengths, and record the position correspondence relationship. The generator receives the sorted code lengths and orderly generates the prefix codes. Except that the first prefix code is preconfigured, the generator generates a current prefix code by adding one to the adjacently previous prefix code and then shifting left by a certain number of bits. The sequence regulator is used to receive the prefix codes corresponding to the sorted code lengths, and regulates the sequence of the prefix codes corresponding to the sorted code lengths according to the position correspondence relationship recorded by the sort indexer to obtain the prefix codes corresponding to the code lengths.

  • Patent number: 8637043
    Abstract: The inventors have discovered that a CK?8-1 truncation variant, CK?8-1 (25-116), is a bifunctional ligand for two distinct GPCRs, chemokine receptor CCR1 and formyl peptide receptor like 1 (FPRL1). Hence, the inventors have discovered that, in addition to its functional activity on CCR1, CK?8-1(25-116) is also a functional ligand for the GPCR receptor FPRL1 that is involved in inflammatory reactions and innate immunity by recruiting monocytes and neutrophils. In addition, the inventors have discovered an alternatively spliced exon of CK?8-1, named SHAAGtide. SHAAGtide, along with its parent chemokine CK?8-1 (25-116), is fully functional on both monocytes and neutrophils that are known to express FPRL1. This application relates generally to enhancing immune responses. Such immune responses may be elicited by vaccine administration. Compositions and methods for inducing or enhancing an immune response to an antigen are provided.

  • Publication number: 20120325989
    Abstract: A fastening mechanism for fastening a first object to a second object, the fastening mechanism includes a first fastening member, a driven member, a linkage member, and a first supporting member. The first fastening member is rotatably secured to the second object. The driven member is rotatably secured to the second object. The linkage member is connected between the fastening member and the driven member. The first supporting member protrudes from the second object to support the first object. When an external force is exerted on the driven member, the driven member is capable of rotating to pull the linkage member, thus the linkage member pulls the first fastening member to rotate toward the first supporting member and sandwiches the first object between the first fastening member and the first supporting member so that the first object is fastened to the second object.
