  • Agha-mohammadi, Ali-akbar; Ure, Nazim Kemal; How, Jonathan P.; Vian, John (Institute of Electrical and Electronics Engineers (IEEE), 2014-09)
    In persistent missions, taking system’s health and capability degradation into account is an essential factor to predict and avoid failures. The state space in health-aware planning problems is often a mixture of continuous ...
  • Dryden, Emily B.; Guillemin, Victor W.; Sena-Dias, Rosa Isabel (American Mathematical Society, 2011-10)
    Let M[superscript 2n] be a symplectic toric manifold with a fixed T[superscript n]-action and with a toric Kähler metric g. Abreu (2003) asked whether the spectrum of the Laplace operator Δ[subscript g] on C∞ (M) determines ...
  • Magagnin, Valentina; Mauri, Maurizio; Cipresso, Pietro; Mainardi, Luca; Brown, Emery N.; Cerutti, Sergio; Villamira, Marco; Barbieri, Riccardo (Institute of Electrical and Electronics Engineers, 2010-09)
    The study of emotions elicited by human-computer interactions is a promising field that could lead to the identification of specific patterns of affective states. We present a heart rate variability (HRV) assessment of the ...
  • Choma, Michael A.; Suter, Melissa J.; Vakoc, Benjamin; Bouma, Brett E.; Tearney, Guillermo J. (Society of Photo-optical Instrumentation Engineers, 2010-09)
    Drosophila melanogaster (fruit fly) is a central organism in biology and is becoming increasingly important in the cardiovascular sciences. Prior work in optical imaging of the D. melanogaster heart has focused on static ...
  • Chen, Dye-Zone A.; Chen, Gang (Global Digital Central, 2010-01)
    We present a calculation of the thermally generated electromagnetic flux propagating along the in-plane direction of a polar, thin film. The approach is based on fluctuational electrodynamics and the fluctuation-dissipation ...
  • Tow, Emily W.; Lienhard, John H. (International Desalination Association, 2013-10)
    Humidification-dehumidification is a promising technology for decentralized, small-scale desalination, but high energy consumption and large dehumidifier size are disadvantages. Direct-contact dehumidification in bubble ...
  • Schulz, Norbert S.; Huenemoerder, David P.; Ji, Li; Yao, Y.; Canizares, Claude R. (American Astronomical Society, 2009-01)
    We observed at very high spectral resolution the prototype Z-source Cyg X-2 twice along its entire X-ray spectral variation pattern. In this preliminary analysis, we find an extended accretion disk corona (ADC) exhibiting ...
  • Cantillon-Murphy, Padraig; Wald, L. L.; Zahn, Markus (Elsevier, 2009-11)
    In the presence of alternating-sinusoidal or rotating magnetic fields, magnetic nanoparticles will act to realign their magnetic moment with the applied magnetic field. The realignment is characterized by the nanoparticle's ...
  • Golyk, Vladyslav A.; Kruger, Matthias; Kardar, Mehran (American Physical Society, 2012-04)
    The heat radiated by objects smaller than or comparable in size to the thermal wavelength can be very different from the classical blackbody radiation as described by the Planck and Stefan-Boltzmann laws. We use methods ...
  • Tian, Zhiting; Lee, Sangyeop; Chen, Gang (ASME International, 2013-05)
    Solid-state thermoelectric devices are currently used in applications ranging from thermocouple sensors to power generators in space missions, to portable air-conditioners and refrigerators. With the ever-rising demand ...
  • Esfarjani, Keivan; Chen, Gang; Stokes, Harold T. (American Physical Society, 2011-08)
    Using harmonic and anharmonic force constants extracted from density functional calculations within a supercell, we have developed a relatively simple but general method to compute thermodynamic and thermal properties of ...
  • Zhang, Qian; Cao, Feng; Liu, Weishu; Lukas, Kevin; Yu, Bo; Chen, Shuo; Opeil, Cyril; Broido, David; Chen, Gang; Ren, Zhifeng (American Chemical Society, 2012-06)
    We present detailed studies of potassium doping in PbTe[subscript 1– y]Se[subscript y] (y = 0, 0.15, 0.25, 0.75, 0.85, 0.95, and 1). It was found that Se increases the doping concentration of K in PbTe as a result of the ...
  • Gouker, Pascale M.; Gadlage, Matthew J.; Bhuva, Bharat L.; Narasimham, Balaji; Schrimpf, Ronald D. (Institute of Electrical and Electronics Engineers, 2009-12)
    Heavy-ion-induced single events transients (SETs) in advanced digital circuits are a significant reliability issue for space-based systems. SET pulse widths in silicon-on-insulator (SOI) technologies are often significantly ...
  • Chesler, Paul M.; Lekaveckas, Mindaugas; Rajagopal, Krishna (Springer-Verlag, 2013-10)
    We compute and study the drag force acting on a heavy quark propagating through the matter produced in the collision of two sheets of energy in a strongly coupled gauge theory that can be analyzed holographically. Although ...
  • Lusztig, George; Vogan, David A. (Institute of Mathematics, Academia Sinica, )
    0.1. LetW be aWeyl group with standard set of generators S; let ≤ be the Bruhat order on W. In [KL1],[KL2], certain polynomials ... N, u is an indeterminate) were defined and computed in terms of an algorithm for any y ...
  • Beatty, Anne; Petacchi, Reining; Zhang, Haiwen (Springer-Verlag, 2012-06)
    We provide large sample evidence that credible hedge commitments reduce the agency costs of debt and that accounting conservatism enhances hedge commitments. We examine 2,338 bank loans entered into by 263 mandatory ...
  • Bell, Stephen P.; Kaguni, Jon M. (Cold Spring Harbor Laboratory Press, 2013-04)
    Loading of the replicative DNA helicase at origins of replication is of central importance in DNA replication. As the first of the replication fork proteins assemble at chromosomal origins of replication, the loaded helicase ...
  • Larkoski, A. J.; Lopez-Villarejo, J. J.; Skands, P. (American Physical Society, 2013-03)
    We present an antenna shower formalism that includes helicity dependence for massless partons. The formalism applies to both traditional (global) showers and sector-based variants. We combine the shower with vincia’s ...
  • Fox, James G.; Ge, Zhongming; Whary, Mark T.; Erdman, Susan E.; Horwitz, B. H. (Nature Publishing Group, 2010-10)
    Pioneering work in the 1990s first linked a novel microaerobic bacterium, Helicobacter hepaticus, with chronic active hepatitis and inflammatory bowel disease in several murine models. Targeted H. hepaticus infection ...
  • Swennes, Alton G.; Sheh, Alexander; Parry, Nicola M. A.; Muthupalani, Sureshkumar; Lertpiriyapong, Kvin; Fox, James G.; Garcia, Alexis (Public Library of Science, 2014-09)
    Farnesoid X receptor (FXR) is a nuclear receptor that regulates bile acid metabolism and transport. Mice lacking expression of FXR (FXR KO) have a high incidence of foci of cellular alterations (FCA) and liver tumors. Here, ...
