We study supercontinuum generation using numerical simulations of the nonlinear propagation along hollow-core fibers at different pump wavelengths ranging from 400 nm to 2 μm. A general hollow fiber compressor design strategy is presented.
Genetic diversity was investigated using assay of vertical slab ployacrylamide gel electrophoresis for the nine populations of Fenneropenaeus penicillatus. The results showed high levels of genetic diversity in each of the nine F. penicillatus populations. The mean number of alleles per locus ranged from 1.3333 to 1.6667, with a average of 1.4148. And the mean effective number of alleles per locus...
Genetic diversity and differentiation were investigated using assay of vertical slab ployacrylamide gel electrophoresis for the nine populations of Marsupenaeus japonicus. The results showed high levels of genetic diversity in each of the nine M. japonicus populations. The mean number of alleles per locus ranged from 1.0000 to 1.0152, with a average of 1.0017, and the mean effective number of alleles...
In an era of increasingly complex biological datasets, one of the key steps in gene functional analysis comes from clustering genes based on co-expression. Biclustering algorithms can identify gene clusters with local co-expressed patterns, which are more likely to define genes functioning together than global clustering methods. However, these algorithms are not effective in uncovering gene regulatory...
Classification of high-dimensional data generally requires enormous processing time. In this paper, we present a fast two-stage method of support vector machines, which includes a feature reduction algorithm and a fast multiclass method. First, principal component analysis is applied to the data for feature reduction and decorrelation, and then a feature selection method is used to further reduce...
