Shared-memory multiprocessors have dominated all platforms from high-end to desktop computers. On such platforms, it is well known that the interconnect between the processors and the main memory has become a major bottleneck. The bandwidth-aware job scheduling is an effective and relatively easy-to-implement way to relieve the bandwidth contention.(More)
Src homology 2 (SH2) domains are the largest family of interaction modules encoded by the human genome to recognize tyrosine-phosphorylated sequences and thereby play pivotal roles in transducing and controlling cellular signals emanating from protein-tyrosine kinases. Different SH2 domains select for distinct phosphopeptides, and the function of a given(More)
A spore-forming, anaerobic, syntrophic fatty-acid-oxidizing bacterium, strain 19J-3(T), was isolated from a distilled-spirit-fermenting cellar in Hebei Province, China. The cells were slightly curved rods with a spore at the end of the cell. The optimal temperature for growth was around 37 degrees C and growth occurred in the range 25-45 degrees C. The pH(More)
Cross-ISA (Instruction Set Architecture) system-level virtual machine has a significant research and practical value. For example, several recently announced virtual smart phones for iOS which run smart phone applications on x86 based PCs are deployed on cross-ISA system level virtual machines. Also, for mobile device application development, by emulating(More)
Protein kinase CK2 exhibits oncogenic activity in mice and is over-expressed in a number of tumors or leukemic cells. On the basis of its amino acid sequence and a wealth of experimental information, CK2 has traditionally been classified as a protein serine/threonine kinase. In contrast to this traditional view of CK2, recent evidence has shown that CK2 can(More)
The Src homology (SH) 3 domain has been shown recently to bind peptide sequences that lack the canonical PXXP motif. The diverse specificity in ligand recognition for a group of 15 SH3 domains has now been investigated using arrays of peptides derived from the proline-rich region of the SH2 domain-containing leukocyte protein of 76 kDa (SLP-76). A screen of(More)
The convergence of caspase and protein kinase signaling pathways has become increasingly evident, as illustrated by the protection of caspase substrates from cleavage upon undergoing phosphorylation at or near to their caspase recognition motifs. To investigate the global role of phosphorylation in the regulation of caspase signaling, we designed a peptide(More)
Two obligate anaerobic bacterial strains (5-3-Z(T) and Y4-1) were isolated from river sediment and rice field mud, respectively. They degraded straight-chain fatty acids with 4-8 carbon atoms in syntrophic association with methanogens, however, neither tested branch-chain fatty acids nor could benzoate be degraded. The strains formed spores when cocultured(More)
Systematic identification of direct protein-protein interactions is often hampered by difficulties in expressing and purifying the corresponding full-length proteins. By taking advantage of the modular nature of many regulatory proteins, we attempted to simplify protein-protein interactions to the corresponding domain-ligand recognition and employed peptide(More)
