A novel scheme for item-based recommendation is proposed in this paper. In our framework, the items are described by an undirected weighted graph Q = (V,epsiv). V is the node set which is identical to the item set, and epsiv is the edge set. Associate with each edge eij isin epsiv is a weight omegaij ges 0, which represents similarity between items i and j.(More)
BACKGROUND/AIMS Although early studies show that Mdm2 is the primary E3 ubiquitin ligase for the p53 tumor suppressor, an increasing amount of data suggests that p53 ubiquitination and degradation are more complex than once thought. Here, we investigated the role of RNF125, a non-Mdm2 ubiquitin-protein ligase, in the regulation of p53. METHODS AND RESULTS(More)
Base on the development of geographic information application system (GIAS) building technology and the demand of "vertical multi-level and lateral multi-branch" organization for industry geographic information applications, in the paper, we reveals the background and necessity to establish the GIAS platform and the multilevel structure-oriented GIAS(More)
