When these networks are subject to some random or deliberate attacks, some nodes in the network fail, which causes a decline in the network performance. In order to make the network run normally, some of the failed nodes must be recovered. In the case of limited recovery resources, an effective key node identification method can find the key recovering node in the failed nodes, by which the network performance can be recovered most of the failed nodes. We propose two key recovering node identification methods for spatial networks, which are the Euclidean-distance recovery method and the route-length recovery method. Simulations on homogeneous and heterogeneous spatial networks show that the proposed methods can significantly recover the network performance.展开更多

Fingerprint minutiae data and the cryptographic key are merged together by a multivariable linear function. First, the minutiae data are bound by a set of random data through the linear function. The number of the function’s variables is determined by the required number of matched minutiae. Then, a new key de- rived from the random data is used to encrypt the cryptographic key. Lastly, the binding data are protected using fuzzy vault scheme. The proposed scheme provides the system with the flexibility to use changeable number of minutiae to bind/recover the protected key and a unified method regardless of the length of the key.展开更多

Simultaneously,bacterial culture of various organ tissues was performed and bacterial and endotoxin translocation were observed.Results:Compared with group 1,serum malondialdehyde, alanine aminotransferase and aspartate aminotransferase levels were significantly decreased(all P<0.05) and serum superoxide dismutase level was significantly increased(P<0.05) in the group Ⅲ. However,there were no significant differences in these indices between groups Ⅱ and Ⅲ(P>0.05). The rate of bacterial translocation in the groups Ⅱ and Ⅲ was significantly lower than in the group Ⅰ(P<0.05),and no significant difference was observed between groups Ⅱ and Ⅲ(P>0.05). Conclusions:Intestinal function-recovering decoction can significantly reduce endotoxin and bacterial translocation and stabilize enteral oxidative-antioxidative balance.展开更多
