ii ACKNOWLEDGMENTS This was a large-scale project that could not have been completed without the efforts and cooperation of many programs, agencies, and individuals. The authors wish to thank the directors and staff at the programs included in this project. They were willing to answer questionnaires, surveys, and sit through lengthy interviews to assist in(More)
It has been shown that stacking a set of known good dice into a 3D chip array may be beneficial in terms of system performance and footprint area. This paper demonstrates that, in the general sense, it is also beneficial to arrange chips into a 3D stack from yield and cost perspectives. It is shown that an optimal point occurs where cost is minimized by(More)
The NSF-funded OptIPuter project [see www.optiputer.net and special issue of Future Generation Computer Systems (FGCS), Volume 25, Issue 2, February 2009] has been exploring for the last six years how user-controlled 10Gbps dedicated lightpaths (lambdas) can provide direct access to global data repositories, scientific instruments, and computational(More)

Two fundamental concepts of geometric control theory, (A,B)-invariant and controllability subspaces, are discussed in terms of spaces spanned by closed loop eigenvectors. Included is a characterization of V*, R*, the supremal (A,B)-invariant and controllability subspaces contained in the kernel of some map. Applying ideas found in numerical analysis(More)
The wrench-closure workspace of parallel cable-driven mechanisms is the set of poses for which any wrench can be produced at the end-effector by a set of a non-negative cable tensions. It is already known that the boundary of the constant-orientation wrench-closure workspace of a planar parallel cable-driven mechanism is composed of segments of conic(More)
of Washington launch a 5-year, $37.8 m illion cross-institutional effort w ith support from the Gordon and Betty M oore Foundation and Alfred P. Sloan Foundation Washington, D.C. — A new multi-million dollar collaboration will enable university researchers to harness the full potential of the data-rich world that characterizes all fields of science and(More)
What is this tool? This tool provides examples of several strategies that have proven effective in improving performance on several of the Patient Safety Indicators (PSIs). The information is derived from a project conducted in several hospitals in northern California. Who are the target audiences? Staff members directly involved in the improvement project,(More)
A major bacterial virulence protein is found to be targeted to plant plasma membrane 34 and its action is linked to down-regulation of the expression of an Arabidopsis gene required for 35 innate immunity ABSTRACT 47 48 Many bacterial pathogens of plants and animals deliver effector proteins into host cells to 49 promote infection.
