Joint high-dimensional Bayesian variable and covariance selection with an application to eQTL analysis January 26, 2012 2:30 p.m. Anindya Bhadra Abstract Abstract: We describe a Bayesian technique to (a) perform a sparse joint selection of significant predictor variables and significant inverse covariance matrix elements of the response variables in a high-dimensional linear Gaussian sparse seemingly […]
Estimation of the Drag Coefficient using the Ocean’s Response to a Hurricane: A Data Assimilation Approach February 17, 2011 2:30 p.m. Sarah Zedler Abstract When wind forces the ocean, a fraction of the momentum is transferred beneath the surface to generate currents and turbulent mixing of the water column. The variable of proportionality representing that […]
Global Sub-micrometer-level Survey of the Mouse Brain Microstructures Using the Knife-Edge Scanning Microscope April 7, 2011 2:30 p.m. Yoonsuck Choe Abstract Recent advances in serial-sectioning microscopy have enabled high-throughput imaging of massive volumes of biological microstructures at a very high resolution. The Knife-Edge Scanning Microscope (KESM), developed and housed at our laboratory at Texas A&M […]
Performance Characteristics of Hybrid MPI/OpenMP Implementations of NAS Parallel Benchmarks SP and BT on Large-Scale Cray XT and BlueGene/P Supercomputers February 3, 2011 2:30 p.m. Xingfu Wu Abstract The NAS Parallel Benchmarks (NPB) are well-known applications with the fixed algorithms for evaluating parallel systems and tools. Multicore clusters provide a natural programming paradigm for hybrid […]
Fast Algorithms for Analyzing Large Collections of Evolutionary Trees November 4, 2010 2:30 p.m. Tiffani Williams Abstract Phylogenetic trees are family trees that represent the relationships between a group of organisms, or taxa. The most popular techniques for reconstructing phylogenetic trees intelligently navigate an exponentially-sized tree space by solving NP-hard optimization problems that best hypothesize […]
