The K-SVD algorithm is a powerful tool in finding an adaptive dictionary for a set of signals via using the sparse representation optimization and constrained singular value decomposition. In this paper, we first review the original K-SVD algorithm as well as some sparse representation algorithms including OMP, Lasso and recently proposed IITH. Secondly, we embed the Lasso and IITH sparse representation...
To develop a genetically engineered Escherichia coli for potential mass production of antibacterial peptide salmine instead of extraction from fish sperm, three primers designed according to amino acid sequence of salmine were used to construct an oligonucleotide fragment (SAL) encoding salmine. SAL was inserted into a pEC vector and transformed into E. coli BL21 (DE3) to construct genetically engineered...
An improved virus evolutionary genetic algorithm was proposed in this article. Some of initial virus individuals were generated from some better host individuals, so that the fitness and the infection of virus individuals were improved and the average fitness of the host population was also improved. At the same time the theory of static multiplication was introduced to the algorithm, as a result...
