    摘要： Managing database indexes includes creating a main index and creating at least one service index that is configured for recording a change to a node to be updated in the main index. Managing database indexes also includes detecting whether an operation that involves the main index and is performed on the database appears in the database, and maintaining the main index using at least one service index in response to the operation that involves the main index and is performed on the database, appearing in the database. The maintaining is performed based on changes to a node to be updated in the main index that are recorded in the at least one service node.

    摘要： The present invention relates to the technical field of data or file synchronization. In particular, the present invention relates to a method and system for data synchronization using character string matching. Provided are a method, computer program product, and system for data synchronization between a source node and target node. An old copy and a new copy of data to be synchronized is received. A block map is generated according to the difference determined using character string matching between the old copy and the new copy. The block map, which includes the position information of unchanged blocks and the position information and contents of changed blocks, is transmitted to a target node.

    摘要： An assembly of a wrench and a socket. The wrench has a penetrating driving hole, which has a retaining ring mounted therein. The socket, having a front end and a tail end, comprises a socketing portion axially extended between the front end and the tail end thereof for driving a fastening element. The socket comprises a retaining portion formed on the periphery thereof. The retaining portion has a retaining groove arranged at retaining corners radially indented for matching the retaining ring. The retaining groove is positioned between the front end and the tail end. The retaining portion further has a buffer groove formed between the retaining groove and the front end, so as to allow the buffer groove to successively provide a buffer or damping effect with the retaining ring when the retaining groove is decoupled from the retaining ring. Accordingly, the user is allowed to control his/her force more easily and improves the operational safety for the process of pulling out of the socket.

    摘要： A method and apparatus of adaptive image and video coding including an alternative transform other than the discrete cosine transform (DCT) and discrete sine transform (DST) type VII (DST-VII) are disclosed. For at least one block size belonging to the size group, a transform from multiple transforms comprising an alternative transform in addition to DCT and DST-VII is selected and applied to a current block. The alternative transform may correspond to DCT type IV (DCT-IV) or DST type IV (DST-IV).
