  • Strigari, L.; Billard, Julien; Figueroa-Feliciano, Enectali (American Physical Society, 2014-01)
    As direct dark matter experiments continue to increase in size, they will become sensitive to neutrinos from astrophysical sources. For experiments that do not have directional sensitivity, coherent neutrino scattering ...
  • Niu, Sidi; Golowich, Steven E.; Ingle, Vinay K.; Manolakis, Dimitris G. (SPIE, 2013-02)
    Most chemical gas detection algorithms for long-wave infrared hyperspectral images assume a gas with a perfectly known spectral signature. In practice, the chemical signature is either imperfectly measured and/or exhibits ...
  • Rechkoblit, Olga; Delaney, James C.; Essigmann, John M.; Patel, Dinshaw J.; Essigmann, John M. (Elsevier, 2011-06)
    DNA is susceptible to alkylation damage by a number of environmental agents that modify the Watson-Crick edge of the bases. Such lesions, if not repaired, may be bypassed by Y-family DNA polymerases. The bypass polymerase ...
  • Ramanna, Karthik; Skinner, Douglas J.; Kothari, S. P. (Elsevier, 2010-09)
    Based on extant literature, we review the positive theory of GAAP. The theory predicts that GAAP’s principal focus is on control (performance measurement and stewardship) and that verifiability and conservatism are critical ...
  • Barnum, Sam; Barsotti, Lisa; Blackburn, Lindy L.; Bodiya, Timothy Paul; Corbitt, Thomas R.; Donovan, Frederick J.; Dwyer, S.; Evans, Matthew J.; Foley, S.; Fritschel, Peter K.; Harry, Gregory; Hughey, B.; Katsavounidis, Erotokritos; MacInnis, Myron E.; Mason, Kenneth R.; Matichard, Fabrice; Mavalvala, Nergis; Mittleman, Richard K.; Shapiro, B.; Shoemaker, David H.; Smith, N. D.; Soto, J.; Stein, A. J.; Waldman, S. J.; Weiss, Rainer; Wipf, Christopher; Zucker, Michael E. (Institute of Physics/American Astronomical Society, 2012-08)
    We present the results of a LIGO search for gravitational waves (GWs) associated with GRB 051103, a short-duration hard-spectrum gamma-ray burst (GRB) whose electromagnetically determined sky position is coincident with ...
  • Liu, Hongwan; Slatyer, Tracy Robyn (American Physical Society, 2018-07)
    Measurements of the temperature of the baryons at the end of the cosmic dark ages can potentially set very precise constraints on energy injection from exotic sources, such as annihilation or decay of the dark matter. ...
  • Cavecchi, Y.; Patruno, A.; Haskell, B.; Watts, A. L.; Levin, Y.; Linares, Manuel Alegret; Altamirano, D.; Wijnands, R.; van der Klis, M. (Institute of Physics/American Astronomical Society, 2011-10)
    The recently discovered accreting X-ray pulsar IGR J17480–2446 spins at a frequency of ~11 Hz. We show that Type I X-ray bursts from this source display oscillations at the same frequency as the stellar spin. IGR J17480–2446 ...
  • Park, Jun-geun; Curtis, Dorothy; Teller, Seth; Ledlie, Jonathan (IEEE Communications Society, 2011-04)
    Many indoor localization methods are based on the association of 802.11 wireless RF signals from wireless access points (WAPs) with location labels. An “organic” RF positioning system relies on regular users, not dedicated ...
  • LHCB Collaboration; Williams, Michael (Springer-Verlag, 2013-04)
    During 2011 the LHCb experiment at CERN collected 1.0 fb ⁻¹ of √s = 7 TeV pp collisions. Due to the large heavy quark production cross-sections, these data provide unprecedented samples of heavy flavoured hadrons. The first ...
  • Sun, Chengzhen; O’Hern, Sean C.; Au, Harold; Boutilier, Michael Stephen Hatcher; Hadjiconstantinou, Nicolas; Karnik, Rohit (American Chemical Society (ACS), 2014-01)
    Gas transport through intrinsic defects and tears is a critical yet poorly understood phenomenon in graphene membranes for gas separation. We report that independent stacking of graphene layers on a porous support exponentially ...
  • Abravanel, Ronen; Faghfoor Maghrebi, Mohammad; Jaffe, Robert L. (American Physical Society (APS), 2011-09)
    We formulate the Babinet Principle (BP) as a relation between scattering amplitudes and combine it with multiple scattering techniques to derive new properties of electromagnetic Casimir forces. We show that the Casimir ...
  • Dow, Eric A; Wang, Qiqi (ASME International, 2015-06)
    Geometric variability increases performance variability and degrades the mean performance of turbomachinery compressor blades. These detrimental effects can be reduced by using robust optimization to design the blade ...
  • Ji, L.; Schulz, Norbert S.; Nowak, Michael A. (IOP Publishing, 2010-07)
    4U 1822–371 is one of the prototype accretion disk coronal sources with an orbital period of about 5.6 hr. The binary is viewed almost edge-on at a high inclination angle of 83°, which makes it a unique candidate to study ...
  • Fernandez del Campo, Pablo; Nguyen, Ngoc Cuong; Roca, X.; Peraire, Jaime (American Institute of Aeronautics and Astronautics (AIAA), 2016-01)
    We present a high-order implicit large-eddy simulation (ILES) approach for simulating transitional turbulent flows. The approach consists of an Interior Embedded Discontinuous Galerkin (IEDG) method for the discretization ...
  • Drela, Mark; Persson, Per-Olof; Peraire, Jaime; Uranga Cabrera, Alejandra (American Institute of Aeronautics and Astronautics, 2009-06)
    The present work aims at predicting the formation of laminar separation bubbles (LSB) and the related transition to turbulence by means of Implicit Large Eddy Simulations with a high-order Discontinuous Galerkin (DG) ...
  • Smalyuk, V. A.; Betti, R.; Delettrez, J. A.; Glebov, V. Yu.; Meyerhofer, D. D.; Radha, P. B.; Regan, S. P.; Sangster, T. C.; Sanz, J.; Seka, W.; Stoecki, C.; Yaakobi, B.; Frenje, Johan A.; Li, Chikang; Petrasso, Richard D.; Seguin, Fredrick Hampton (American Physical Society, 2010-04)
    Direct-drive implosions with 20-μm-thick glass shells were conducted on the Omega Laser Facility to test the performance of high-Z glass ablators for direct-drive, inertial confinement fusion. The x-ray signal caused by ...
  • Baustian, Kelly J.; Cziczo, Daniel James; Wise, Matthew E.; Pratt, Kerri A.; Kulkarni, Gourihar; Hallar, A. Gannet; Tolbert, Margaret A. (American Geophysical Union (AGU), 2012-03)
    In this study chemical compositions of background aerosol and ice nuclei were examined through laboratory investigations using Raman spectroscopy and field measurements by single-particle mass spectrometry. Aerosol sampling ...
  • Stephens, Ifan; Elias, Joseph Spanjaard; Shao-Horn, Yang (American Association for the Advancement of Science (AAAS), 2015-10)
    Platinum catalyzes several chemical and electrochemical reactions that are central to humankind's use of energy, such as the electrochemical reduction of molecular oxygen, carbon monoxide oxidation, and the water-gas shift ...
  • Yano, Masayuki; Modisette, James; Darmofal, David L. (American Institute of Aeronautics and Astronautics, 2011-06)
    This work presents an adaptive framework for a higher-order discretization of the Reynolds-averaged Navier-Stokes (RANS) equations. The adaptation strategy is based on an output-based error estimate and explicit control ...
  • Rigotti, Mattia; Barak, Omri; Warden, Melissa R.; Wang, Xiao-Jing; Daw, Nathaniel D.; Miller, Earl K.; Fusi, Stefano (Nature Publishing Group, 2013-05)
    Single-neuron activity in the prefrontal cortex (PFC) is tuned to mixtures of multiple task-related aspects. Such mixed selectivity is highly heterogeneous, seemingly disordered and therefore difficult to interpret. We ...
