      Barnes, Stuart I.; Buchhave, Lars A.; Phillips, David; Shectman, Stephen; Walsworth, Ronald; e.a. (Society of Photo-Optical Instrumentation Engineers (SPIE), 2016-06)
      The Kepler mission highlighted that precision radial velocity (PRV) follow-up is a real bottleneck in supporting transiting exoplanet surveys. The limited availability of PRV instruments, and the desire to break the “1 ...
    • Wishbone: Profile-based Partitioning for Sensornet Applications 

      Newton, Ryan; Toledo, Sivan; Girod, Lewis D.; Balakrishnan, Hari; Madden, Samuel R. (USENIX Association, 2009-01)
      The ability to partition sensor network application code across sensor nodes and backend servers is important for running complex, data-intensive applications on sensor platforms that have CPU, energy, and bandwidth ...
    • Wisteria Floribunda Agglutinin-Labeled Perineuronal Nets in the Mouse Inferior Colliculus, Thalamic Reticular Nucleus and Auditory Cortex 

      Fader, Sarah; Imaizumi, Kazuo; Yanagawa, Yuchio; Lee, Charles (MDPI AG, 2016-04)
      Perineuronal nets (PNNs) are specialized extracellular matrix molecules that are associated with the closing of the critical period, among other functions. In the adult brain, PNNs surround specific types of neurons, however ...
    • Witchcraft, bureaucraft, and the social life of (US)AID in Haiti 

      James, Erica C. (Wiley Blackwell, 2012-02)
      In this article I discuss the unintended consequences of humanitarian and development assistance provided to “victims of human rights abuses” in Haiti in the years following the restoration of democracy in 1994. Such ...
    • Withholding or withdrawing invasive interventions may not accelerate time to death among dying ICU patients

    • Within- and cross-modal distance information disambiguate visual size- perception 

      Battaglia, Peter W.; Kersten, Daniel; Machulla, Tonja; Schrater, Paul R.; Ernst, Marc O.; e.a. (Public Library of Science, 2010-01)
      Perception is fundamentally underconstrained because different combinations of object properties can generate the same sensory information. To disambiguate sensory information into estimates of scene properties, our brains ...
    • Witnesses to Design: A Phenomenology of Comparative Design 

      Bucciarelli, Louis; Earl, Chris; Eckert, Claudia; Blackwell, Alan (MIT Press Journals, 2009-02)
      This research is concerned with describing the experience of being a designer and doing design. Many case studies have described individual experiences, both of designers reflecting on their own work, and academic studies ...
    • Witt vectors and K-theory of automorphisms via noncommutative motives 

      Trigo Neri Tabuada, Goncalo Jorge (Springer Berlin Heidelberg, 2013-06)
