he quest for the Teraflops Super-~puter to operate at ,eak speed of 10" ting-point operations per sec is almost a decade old, and only one three-year computer generation from being fulfilled. The acceleration of its development would require an ultracomputer. First-generation, ultracomputers are networked computers using switches that interconnect thousands(More)
MyLifeBits is a project to fulfill the Memex vision first posited by Vannevar Bush in 1945. It is a system for storing all of one's digital media, including documents, images, sounds, and videos. It is built on four principles: (1) collections and search must replace hierarchy for organization (2) many visualizations should be supported (3) annotations are(More)
Highly unsaturated fatty acid (HUFA) synthesis in Atlantic salmon (Salmo salar) was known to be influenced by both nutritional and environmental factors. Here we aimed to test the hypothesis that both these effectors involved similar molecular mechanisms. Thus, HUFA biosynthetic activity and the expression of fatty acyl desaturase and elongase genes were(More)
By 2047, almost all information will be in cyberspace (1984)-including all knowledge and creative works. All information about physical objects including humans, buildings, processes, and organizations will be online. This trend is both desirable and inevitable. Cyberspace will provide the basis for wonderful new ways to inform, entertain, and educate(More)
BACKGROUND Expansion of aquaculture is seriously limited by reductions in fish oil (FO) supply for aquafeeds. Terrestrial alternatives such as vegetable oils (VO) have been investigated and recently a strategy combining genetic selection with changes in diet formulations has been proposed to meet growing demands for aquaculture products. This study(More)
Running title: HUFA gene expression in salmon fed vegetable oil Abstract Fish are an important dietary source of the long-chain C 20 and C 22 highly unsaturated fatty acids (HUFA), arachidonate (20:4n-6), eicosapentaenoate (20:5n-3) and docosahexaenoate (22:6n-3), that are crucial to the health of higher vertebrates and that can be beneficial in human(More)
