  • Waller, Laura; Kim, Jungik; Shao-Horn, Yang; Barbastathis, George (Optical Society of America, 2009-08)
    We have developed a system that uses two 1D interferometric phase projections for reconstruction of 2D water content changes over time in situ in a proton exchange membrane (PEM) fuel cell system. By modifying the filtered ...
  • Tu, Shui Ping; Quante, Michael; Bhagat, Govind; Takaishi, Shigeo; Cui, Guanglin; Yang, Xiang Dong; Muthuplani, Sureshkumar; Shibata, Wataru; Fox, James G.; Pritchard, D. Mark; Wang, Timothy C. (American Association for Cancer Research, 2011-04)
    IFN-γ mediates responses to bacterial infection and autoimmune disease, but it is also an important tumor suppressor. It is upregulated in the gastric mucosa by chronic Helicobacter infection; however, whether it plays a ...
  • Hutchinson, Ian H. (American Physical Society, 2012-06)
    Large-scale particle-in-cell calculations of the plasma wake interactions of two negatively charged grains smaller than the Debye length are carried out using the coptic code over a wide range of subsonic plasma flow ...
  • Krasovskiy, Yuriy P.; Stone, Peter H. (American Meteorological Society, 2009-04)
    The authors introduce a four-box interhemispheric model of the meridional overturning circulation. A single box represents high latitudes in each hemisphere, and in contrast to earlier interhemispheric box models, low ...
  • Lemke, Angelika K.; Sandy, John D.; Voigt, Henning; Dreier, Rita; Lee, Jennifer H.; Grodzinsky, Alan J.; Mentlein, Rolf; Fay, Jakob; Schunke, Michael; Kurz, Bodo (Springer-Verlag, 2010-03)
    Pro-inflammatory cytokines induce meniscal matrix degradation and inhibition of endogenous repair mechanisms, but the pathogenic mechanisms behind this are mostly unknown. Therefore, we investigated details of interleukin-1 ...
  • Moawwad, Ahmed; Khadkikar, Vinod; Kirtley, James L., Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2012-10)
    This paper proposes a stationary-frame control method for voltage unbalance compensation using Interline Photovoltaic (I-PV) power system. I-PV power systems are controlled to compensate voltage unbalance autonomously. The ...
  • Khadkikar, Vinod; Kirtley, James L., Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
    This paper presents a new system configuration for a large-scale Photovoltaic (PV) power system with multi-line transmission/distribution networks. A PV power plant is reconfigured in a way that two adjacent power system ...
  • Antras, Pol; Costinot, Arnaud (American Economic Association, 2010-12)
    This paper develops a simple model of international trade with intermediation. We consider an economy with two islands and two types of agents, farmers and traders. Farmers can produce two goods, but in order to sell ...
  • Pfeiffer, Andrew T.; Murray, Richard A.; Lin, Yijun; Wukitch, Stephen James; Binus, Alan; Gwinn, D. (Institute of Electrical and Electronics Engineers, 2009-08)
    ICRF operations with Alcator C-Mod consists of 4 transmitters, of which two are tunable within the 40 MHz to 80 MHz band. These transmitters were comprised of 3 stages all of which employed vacuum tube amplifiers. As a ...
  • Bourouiba, Lydia; Bartello, Peter (Cambridge University Press, 2007-08)
    Rotating homogeneous turbulence in a finite domain is studied using numerical simulations, with a particular emphasis on the interactions between the wave and zero-frequency modes. Numerical simulations of decaying homogeneous ...
  • Antras, Pol; Costinot, Arnaud (American Economic Association, 2010-05)
    The theory of international trade has paid scant attention to market institutions. Neither neoclassical theory nor new trade models typically specify the process by which supply and demand meet. Yet in the real world, ...
  • Oates, Daniel E.; Eom, Chang-Beom; Folkman, Chad M; Choi, Kyoung-Jin; Jang, Ho Won (Institute of Electrical and Electronics Engineers, 2009-06)
    We report intermodulation distortion (IMD) in high-quality epitaxial YBa[subscript 2]Cu[subscript 3]O[subscript 7-delta] (YBCO) thick films and multilayers prepared by pulsed-laser deposition (PLD) using multiple targets. ...
  • Debelouchina, Galia Tzvetanova; Bayro, Marvin J.; Radford, Sheena E.; Griffin, Robert Guy; Platt, Geoffrey W. (American Chemical Society (ACS), 2010-11)
    The deposition of amyloid-like fibrils, composed primarily of the 99-residue protein β2-microglobulin (β2m), is one of the characteristic symptoms of dialysis-related amyloidosis. Fibrils formed in vitro at low pH and low ...
  • Bayro, Marvin J.; Debelouchina, Galia Tzvetanova; Eddy, Matthew Thomas; Birkett, Neil R.; MacPhee, Catherine E.; Rosay, Melanie; Maas, Werner E.; Dobson, Christopher M.; Griffin, Robert Guy (American Chemical Society (ACS), 2011-07)
    We describe magic-angle spinning NMR experiments designed to elucidate the interstrand architecture of amyloid fibrils. Three methods are introduced for this purpose, two being based on the analysis of long-range [superscript ...
  • Weinstein, Dana; Bhave, Sunil A. (Institute of Electrical and Electronics Engineers (IEEE), 2009-12)
    This paper investigates electrostatic transduction of a longitudinal-mode silicon acoustic resonator with internal dielectric films. Geometric optimization of internal dielectrically transduced resonators is derived ...
  • Wada, Hirofumi; Netz, Ronald R.; Alexander-Katz, Alfredo (American Physical Society, 2009-07)
    The stretching response of a single collapsed homopolymer is studied using Brownian dynamic simulations. The irreversibly dissipated work is found to be dominated by internal friction effects below the collapse temperature, ...
  • Acharya, Viral V.; Myers, Stewart C.; Rajan, Raghuram G. (John Wiley & Sons, Inc, 2011-06)
    We develop a model of internal governance where the self-serving actions of top management are limited by the potential reaction of subordinates. Internal governance can mitigate agency problems and ensure that firms have ...
  • Zollo, Loredana; Guglielmelli, Eugenio; Lonini, Luca; Dipietro, Laura; Krebs, Hermano Igo (MIT Press, 2009-06)
    Humans have the ability to learn novel motor tasks while manipulating the environment. Several models of motor learning have been proposed in the literature, but few of them address the problem of retention and ...
  • Dragoi, George (Frontiers Research Foundation, 2013-08)
    Most of our cognitive life depends on our brain's ability to generate internal representations of the external world. The hippocampus is a brain structure that supports the formation of internal representations of the ...
  • Peacock, Thomas; Echeverri, Paula (Cambridge University Press, 2010-06)
    To date, analytical models of internal tide generation by two-dimensional ridges have considered only idealized shapes. Here, we advance the Green function approach to address the generation of internal tides by two-dimensional ...
