    Human locomotion is a rhythmic task in which patterns of muscle activity are modulated by state-dependent feedback to accommodate perturbations. Two popular theories have been proposed for the underlying embodiment of phase ...

  • Marshall, John C.; Smith, K. Shafer (American Meteorological Society, 2008-06)
    Satellite altimetric observations of the ocean reveal surface pressure patterns in the core of the Antarctic Circumpolar Current (ACC) that propagate downstream (eastward) but slower than the mean surface current by about ...
  • Palacios, Tomas; Killat, Nicole; Tapajna, Milan; Faqir, Mustapha; Kuball, Martin (Institution of Electrical Engineers (IEE), 2011-03)
    Electroluminescence (EL) spectroscopy in combination with drift-diffusion simulations was used to prove the presence of impact ionisation in AlGaN/GaN HEMTs illustrated on InGaN back-barrier devices. Regardless of the level ...
  • Maimone, Thomas J.; Kinzel, Tom; Zhang, Yong; Takase, Michael K.; Milner, Phillip John; Buchwald, Stephen Leffler (American Chemical Society (ACS), 2011-10)
    A mechanistic investigation of the Pd-catalyzed conversion of aryl triflates to fluorides is presented. Studies reveal that C–F reductive elimination from a LPd[superscript II](aryl)F complex (L = t-BuBrettPhos or RockPhos) ...
