NarK belongs to the nitrate/nitrite porter (NNP) family in the major facilitator superfamily (MFS) and plays a central role in nitrate uptake across the membrane in diverse organisms, including archaea, bacteria, fungi and plants. Although previous studies provided insight into the overall structure and the substrate recognition of NarK, its molecular… (More)
The NWT was reinforced to get 280 GFLOPS of theoretical peak performance with the addition of 26 PEs to the original 140 PEs. On a CFD simulation of jet engine compressor, we attained active performance speed of 111 GFLOPS using 160 PEs.
By using a congenic non-obese diabetic (NOD) mouse strain that possesses a recombinant major histocompatibility complex (MHC) from a diabetes-resistant sister strain, the CTS mouse, we have previously mapped a second component of the MHC linked susceptibility gene (Idd16) to the <11.8centiMorgan (cM) segment of chromosome 17 adjacent to, but distinct from… (More)
Global warming effects on seaweed beds are already perceptible. Their geographical distributions greatly depend on water temperatures. To predict future geographical distributions of brown alga, Sargassum horneri, forming large beds in the northwestern Pacific, we referred to future monthly surface water temperatures at about 1.1° of longitude and 0.6° of… (More)
NAL Numerical Wind Tunnel (NWT) is a distributed memory parallel computer developed through joint research and development of NAL and Fujitsu. It is based on the analysis of CFD codes developed in NAL. The target performance is more than 100 times faster than VP400.In this paper, the parallel computation model employed in the development of the NWT is… (More)
A portable QCD simulation program running on NWT with 128 PE's shows the performance 0.032 micro sec/link update, which is about 189 times faster than a highly optimized code on CRAY X-MP/48 with four processors. The performance corresponds to 178 GFLOPS sustained speed.
To represent both the basin-scale circulation in the ocean and the local small-scale variations at the same time, a high resolution global ocean general circulation model (OGCM) is essential. Recent progress in parallel computing techniques together with the high ability of computer itself makes it possible to use such a high resolution OGCM for climate… (More)
We have designed a rapid method for the separation of polyunsaturated fatty acids (PUFA, ≥trienes) from non-PUFA, and for estimation of total amounts of PUFA in lipids of aquatic organisms. Lipids from thirty-one species, including marine and fresh water fishes, shell fishes, marine algae, and other aquatic animals, and from terrestrial organisms, were… (More)
Bacteriorhodopsin (bR) is a light-driven proton pump and a model membrane transport protein. We used time-resolved serial femtosecond crystallography at an x-ray free electron laser to visualize conformational changes in bR from nanoseconds to milliseconds following photoactivation. An initially twisted retinal chromophore displaces a conserved tryptophan… (More)
