The Idea of Non-negative Matrix Factorization (NMF) has been implemented in a wide variety of real world applications. To improve the usability of NMF, people usually add some regularization items to constrain the process of matrix factorization. The Regularized Non-negative Matrix Factorization (RNMF) mainly relies on prior knowledge to set the(More)
The temporally dependent component analysis (TDCA) method for blind source separation (BSS) is introduced. As a new principle, it is shown that maximizing the mapping of autocorrelation of source signals can be used to perform BSS. We use the natural gradient algorithm for TDCA and study the mathematical properties of TDCA. Simulations by square temporal(More)
Wild Chinese horseshoe bats have been proven to be natural reservoirs of SARS-like coronaviruses. However, the molecular characterization of key proteins in bats still needs to be explored further. In this study, we used cloning and bioinformatics to analyze the sequence of RIG-I, STAT-1 and IFN-β in the immortalized cell lines from Rhinolophus affinis and(More)
