Publication number: 20100076941Abstract: A system and method for performing a scan of an input sequence in a parallel processor having a shared register file. A two dimensional matrix is generated, having a number of rows representing a number of threads and a number of columns based on the input sequence block size and the number of rows. One or more padding columns may be added to the matrix to avoid or reduce memory bank conflicts. A first traversal of the rows performs a reduction or a scan of each of the rows in parallel, storing the reduction values. The reduction values are used during a second traversal to propagate the reduction values. In a segmented scan, propagation is selectively performed based on flags representing segment boundaries.Type: ApplicationFiled: September 9, 2008Publication date: March 25, 2010Applicant: Microsoft CorporationInventors: Yuri Dotsenko, Naga Govindaraju, Charles Boyd, John Manferdelli, Peter-Pike Sloan

Patent number: 7454293Abstract: A method for enhanced detection and statistical analysis of differentially expressed genes in gene chip microarrays employs: (a) transformation of gene expression data into an expression data matrix (image data paradigm); (b) wavelet denoising of expression data matrix values to enhance their signal-to-noise ratio; and (c) singular value decomposition (SVD) of the wavelet-denoised expression data matrix to concentrate most of the gene expression signal in primary matrix eigenarrays to enhance the separation of true gene expression values from background noise. The transformation of gene chip data into an image data paradigm facilitates the use of powerful image data processing techniques, including a generalized logarithm (g-log) function to stabilize variance over intensity, and the WSVD combination of wavelet packet transform and denoising and SVD to clearly enhance separation of the truly changed genes from background noise.Type: GrantFiled: January 7, 2005Date of Patent: November 18, 2008Assignee: University of Hawai'iInventors: Gordon S.

Publication number: 20080001105Abstract: An apparatus utilizes optical reflectivity (REF) to measure concentrations in liquids. The REF optical system is packaged in a compact and cost-effective form factor. An electronic circuit drives the optical system. The miniaturized REF sensor is situated in an optical-fluidic cell or an optical-fluidic manifold with an optical window in contact with the liquid. Changes in a total internal reflection (TIR) signal are sensitive to temperature and concentration of the liquid.
