  • A note on best approximation and invertibility of operators on uniformly convex Banach spaces 

    Holub, James R. (Hindawi Publishing Corp, 1991-01-01)
    It is shown that if X is a uniformly convex Banach space and S a bounded linear operator onX for which ?I-S?=1, then S is invertible if and only if ?I-12S? <1. From this it follows thatif S is invertible on X then either ...

    Humans, like other animals, are exposed to a continuous stream of signals, which are dynamic, multimodal, extended, and time varying in nature. This complex input space must be transduced and sampled by our sensory systems ...
  • Monkeys and Humans Share a Common Computation for Face/Voice Integration 

    Chandrasekaran, Chandramouli; Lemus, Luis; Trubanova, Andrea; Gondan, Matthias; Ghazanfar, Asif A. (PLOS, 2011-09-29)
    Speech production involves the movement of the mouth and other regions of the face resulting in visual motion cues. These visual cues enhance intelligibility and detection of auditory speech. As such, face-to-face speech ...
  • Underidentification of Autism Spectrum Disorder in Females: A Case Series Illustrating the Unique Presentation of this Disorder in Young Women 

    Trubanova, Andrea; Donlon, Katharine; Kreiser, Nicole L.; Ollendick, Thomas H.; White, Susan W. (Exeley, 2014-05)
    Autism spectrum disorder (ASD) is diagnosed more often in males than females, with the male-to-female gender ratio reported to be around 4.3:1 to 5:1. It is possible that the underrecognition of ASD in females partially ...
  • A Burkholderia pseudomallei Colony Variant Necessary for Gastric Colonization 

    Austin, C. R.; Goodyear, A. W.; Bartek, I. L.; Stewart, A.; Sutherland, M. D.; Silva, E. B.; Zweifel, A.; Vitko, N. P.; Tuanyok, A.; Highnam, G.; Mittelman, D.; Keim, P.; Schweizer, H. P.; Vazquez-Torres, A.; Dow, S. W. C.; Voskuil, M. I. (American Society for Microbiology, 2015-01)
    Diverse colony morphologies are a hallmark of Burkholderia pseudomallei recovered from infected patients. We observed that stresses that inhibit aerobic respiration shifted populations of B. pseudomallei from the canonical ...
  • Ultrahigh Durability Perovskite Solar Cells

    Luo, Elaine; Aylward, Frank O.; Mende, Daniel R.; DeLong, Edward F. (American Society for Microbiology, 2017-11)
    Bacteriophages are numerically the most abundant DNA-containing entities in the oligotrophic ocean, yet how specific phage populations vary over time and space remains to be fully explored. Here, we conducted a metagenomic ...
  • Parallel Evolution of Genome Streamlining and Cellular Bioenergetics across the Marine Radiation of a Bacterial Phylum 

    Getz, Eric W.; Tithi, Saima Sultana; Zhang, Liqing; Aylward, Frank O. (American Society for Microbiology, 2018-09)
    Diverse bacterial and archaeal lineages drive biogeochemical cycles in the global ocean, but the evolutionary processes that have shaped their genomic properties and physiological capabilities remain obscure. Here we track ...
  • High Breakdown Estimation Methods for Phase I Multivariate Control Charts 

    Jensen, Willis A.; Birch, Jeffrey B.; Woodall, William H. (Virginia Tech, 2005)
    The goal of Phase I monitoring of multivariate data is to identify multivariate outliers and step changes so that the estimated control limits are sufficiently accurate for Phase II monitoring. High breakdown estimation ...
