    The SuperCDMS experiment in the Soudan Underground Laboratory searches for dark matter with a 9-kg array of cryogenic germanium detectors. Symmetric sensors on opposite sides measure both charge and phonons from each ...
  • Goncharov, V. N.; Sangster, T. C.; Boehly, T. R.; Hu, S. X.; Igumenshchev, I. V.; Marshall, F. J.; McCrory, R. L.; Meyerhofer, D. D.; Radha, P. B.; Seka, W.; Skupsky, S.; Stoeckl, C.; Casey, Daniel Thomas; Frenje, Johan A.; Petrasso, Richard D. (American Physical Society, 2010-04)
    The performance of triple-picket deuterium-tritium cryogenic target designs on the OMEGA Laser System [T.R. Boehly et al., Opt. Commun. 133, 495 (1997)] is reported. These designs facilitate control of shock heating in ...
  • Drake, Adam; Browne, Edward P.; Phennicie, Ryan T.; Chen, J. (Biomed Central Ltd., 2012-09)
    Lentiviral entry to quiescent lymphocytes represents a 'time bomb' waiting for cellular activation to spread infection. In order to undergo immune activation T cells interact with dendritic cells presenting peptide:MHC ...

    Global dengue virus spread in tropical and sub-tropical regions has become a major international public health concern. It is evident that DENV genetic diversity plays a significant role in the immunopathology of the disease ...
  • Goyal, Vivek K.; Fletcher, Alyson K.; Rangan, Sundeep; Ramchandran, Kannan (Hindawi Publishing Corporation, 2006-03)
    If a signal is known to have a sparse representation with respect to a frame, it can be estimated from a noise-corrupted observation by finding the best sparse approximation to . Removing noise in this manner depends on ...
