A chitinase- and protease-producing bacterium was isolated and identified as Bacillus cereus TKU006. The better condition on our tests for protease and chitinase production was found when the culture was shaken at 25°C for 2 days in 25 mL of medium containing 2% shrimp shell powder (w/v), 0.1% K2HPO4, and 0.05% MgSO4·7H2O. The molecular masses of TKU006(More)
Mycobacterium neoaurum, a member of the Mycobacterium parafortuitum complex, has only rarely been reported as a pathogen of human infections. We report a case of catheter-related bloodstream infection (CRBSI) due to M. neoaurum in a patient on hemodialysis. The isolate was identified by conventional methods as well as by 16S rRNA gene analysis. The patient(More)
It is easy for a multi-layered perception (MLP) to form open plane classification borders, and for a radial basis function network (RBFN) to form closed circular or elliptic classification borders. In contrast, it is difficult for a MLP to form closed circular or elliptic classification borders, and for RBFN to form open plane classification borders. Hence,(More)
Radial basis function network (RBFN), commonly used in the classification applications, has two parameters, kernel center and radius that can be determined by unsupervised or supervised learning. But it has a disadvantage that it considers that all the independent variables have the equal weights. In that case, the contour lines of the kernel function are(More)
