The AI concentration in serum and kidney, contents of creatinine （Cr） and blood urea nitrogen （BUN） in serum were detected, and the renal structure was also observed by optical microscope. The results showed that the A1 concentration in serum and kidney, the contents of Cr and BUN in serum were significantly higher in Al-treated chickens than those in the control group （P〈0.05; P〈0.01） and there was an AlCl3 dose-depended manner. Histopathologically, in the low dose group, acinus renis swelled mildly and there were no apparent pathological changes in nephric tubule and proximal convoluted tubule. In the middle and high dose group, acinus renis swelled, glomerular cells increased, nephric tubule cloudy swelled, and epithelial cells of proximal convoluted tubule swelled. The results indicated that sub-chronic Al exposure impaired the renal structure and function in chickens.展开更多

Function S-rough sets has two forms： function one direction S-rough sets （function one direction singular rough sets） and function two direction S-rough sets （function two direction singular rough sets）. This paper advances the relationship theorem of function S-rough sets and S-rough sets. Function S-rough sets is the general form of S-rough sets, and S-rough sets is the special ease of function S-rough sets. In this paper, applications of function S-rough sets in rough law mining-discovery of system are given. Function S-rough sets is a new research direction of rough sets and rough system.展开更多

The 3-state system reliability analysis often uses flow required andprobability of the device to compute the probability of the system with link-capacity. We use themethod of max-flow and min-cut theorem, give four theorems to reduce 3-state device network withlink-capacity reliability problems to 2-state problems. For practical, relevant network sizes (up to100 components), the algorithm is fast and efficient.展开更多

In this work, a novel algorithm is presented which combines ideas from local learning, constraint- based, and search-and-score techniques in a principled and ef- fective way. It first reconstructs the junction tree of a BN and then performs a K2-scoring greedy search to orientate the local edges in the cliques of junction tree. Theoretical and experimental results show the proposed algorithm is capable of handling networks with a large number of variables. Its comparison with the well-known K2 algorithm is also presented.展开更多

Function S-rough sets is a new theory and method in law mining research.
