The MCHF atomic structure package consists of a series of programs that predict a range of atomic properties and communicate information through les. Several of these have now been modiied for the distributed-memory environment. On the Intel iPSC/860, the restricted amount of memory and the lack of virtual memory required a redesign of the data organization(More)
Regulation of the process of neuronal death plays a central role both during development of the CNS and in adult brain. The transcription factor myocyte enhancer factor 2 (MEF2) plays a critical role in neuronal survival. Cyclin-dependent kinase 5 (Cdk5) mediates neurotoxic effects by phosphorylating and inhibiting MEF2. How Cdk5-dependent phosphorylation(More)
Firstly, the nonnegative matrix factorization with sparseness constraints on parts of the basis matrix (NMFSCPBM) method is proposed in this paper. Secondly, the encrypted watermark is embedded into the big coefficients of the basis matrix that the host video is decomposed into by NMFSCPBM. At the same time, the watermark embedding strength is adaptively(More)
