  • Chernoff, David F.; Bloomfield, Jolyon (American Physical Society, 2014-06)
    Cosmic superstring loops within the galaxy microlens background point sources lying close to the observer-string line of sight. For suitable alignments, multiple paths coexist and the (achromatic) flux enhancement is a ...
  • Andersson, Karl; Bautz, Marshall W.; McDonald, Michael A. (IOP Publishing, 2013-01)
    We use measurements from the South Pole Telescope (SPT) Sunyaev-Zel'dovich (SZ) cluster survey in combination with X-ray measurements to constrain cosmological parameters. We present a statistical method that fits for the ...
  • Reid, Beth A.; Percival, Will J.; Verde, Licia; Spergel, David N.; Skibba, Raman A.; Bahcall, Neta A.; Budavari, Tamas; Frieman, Joshua A.; Fukugita, Masataka; Gott, J. Richard; Gunn, James E.; Zeljko, Ivezic; Knapp, Gillian R.; Kron, Richard G.; Lupton, Robert H.; McKay, Timothy A.; Meiksin, Avery; Nichol, Robert C.; Pope, Adrian C.; Schlegel, David J.; Schneider, Donald P.; Stoughton, Chris; Strauss, Michael A.; Szalay, Alexander S.; Eisenstein, Daniel J.; Tegmark, Max Erik; Vogeley, Michael S.; Weinberg, David H.; York, Donald G.; Zehavi, Idit (Wiley-Blackwell Pubishers, 2010-03)
    We present the power spectrum of the reconstructed halo density field derived from a sample of luminous red galaxies (LRGs) from the Sloan Digital Sky Survey (SDSS) Seventh Data Release (DR7). The halo power spectrum has ...
  • Silvestri, Alessandra; Crittenden, Robert; Hojjati, Alireza; Koyama, Kazuya; Pogosian, Levon; Zhao, Gong-Bo (American Physical Society, 2012-02)
    The next generation of weak lensing surveys will trace the evolution of matter perturbations and gravitational potentials from the matter dominated epoch until today. Along with constraining the dynamics of dark energy, ...
  • Zhao, Gong-Bo; Pogosian, Levon; Silvestri, Alessandra; Zylberberg, Joel (American Physical Society, 2009-05)
    Future weak lensing surveys will map the evolution of matter perturbations and gravitational potentials, yielding a new test of general relativity on cosmic scales. They will probe the relations between matter overdensities, ...
  • Mandel, Ilya; Taylor, Stephen R.; Gair, Jonathan R. (American Physical Society, 2012-01)
    We investigate a novel approach to measuring the Hubble constant using gravitational-wave (GW) signals from compact binaries by exploiting the narrowness of the distribution of masses of the underlying neutron-star population. ...
  • Sze, Vivienne; Chandrakasan, Anantha P.; Sinangil, M. E.; Zhou, M. (Institute of Electrical and Electronics Engineers (IEEE), 2013-07)
    This paper focuses on motion estimation engine design in future high-efficiency video coding (HEVC) encoders. First, a methodology is explained to analyze hardware implementation cost in terms of hardware area, memory size ...
  • Hamilton, Michael R.; Herzog, Howard J.; Parsons, John E. (Elsevier, 2009-02)
    This paper provides a financial analysis for new supercritical pulverized coal plants with carbon capture and sequestration (CCS) that compares the effects of two relevant climate policies. First, an updated cost estimate ...
  • Treleaven, Kyle Ballantyne; Pavone, Marco; Frazzoli, Emilio (American Automatic Control Council, 2012-06)
    Demand-responsive transport (DRT) systems, where users generate requests for transportation from a pickup point to a delivery point, are expected to increase in usage dramatically as the inconvenience of privately-owned ...
  • Paradiso, Joseph A.; Vaucelle, Catherine Nicole; Ishii, Hiroshi (Association for Computing Machinery, 2009-04)
    In this paper we present the design of a cost-effective wearable sensor to detect and indicate the strength and other characteristics of the electric field emanating from a laptop display. Our Electromagnetic Field Detector ...
  • Guan, Kyle C.; Chan, Vincent W. S. (Optical Society of America, 2009-06)
    In this paper, we provide some analytical insights into physical architectures that can serve as benchmarks for designing a cost-efficient WDM metropolitan area network (MAN). For uniform all-to-all traffic and regular ...
  • Dwyer, Morgan; Szajnfarber, Zoe; Selva, Daniel; Crawley, Edward F. (American Institute of Aeronautics and Astronautics, 2014-08)
    Although joint programs are typically formed to reduce costs, recent studies have suggested that joint programs experience larger cost growth than non-joint programs. To explain this phenomenon, we present a model that ...
  • Ghaffari, Mohsen; Lynch, Nancy Ann; Newport, Calvin (Association for Computing Machinery, 2013-07)
    We study upper and lower bounds for the global and local broadcast problems in the dual graph model combined with different strength adversaries. The dual graph model is a generalization of the standard graph-based radio ...
  • Talmadge, Elisabeth Rosem Caitlin; O'Neil, William D. (MIT Press, 2009-12)
    To the Editors (William D. O’Neil writes): Caitlin Talmadge’s analysis of the threat of Iranian action to close the Strait of Hormuz is not only timely but provides many valuable insights.1 Several aspects of this ...
  • Ryan, Stephen (John Wiley & Sons, Inc., 2012-05)
    The typical cost analysis of an environmental regulation consists of an engineering estimate of the compliance costs. In industries where fixed costs are an important determinant of market structure, this static analysis ...
  • Peng, Guowen; Sibener, S. J.; Schatz, George C.; Mavrikakis, Manos; Ceyer, Sylvia (American Chemical Society (ACS), 2011-12)
    Periodic, self-consistent, density functional theory (DFT) calculations are employed to study CO[subscript 2] hydrogenation on Ni(111). CO[subscript 2] hydrogenation with H adsorbed on the surface and with H absorbed in ...
  • MacMinn, C. W.; Szulczewski, Michael Lawrence; Juanes, Ruben (Cambridge University Press, 2011-10)
    The large-scale injection of carbon dioxide (CO[subscript 2]) into saline aquifers is a promising tool for reducing atmospheric CO[subscript 2] emissions to mitigate climate change. An accurate assessment of the post-injection ...
  • MacMinn, C.W.; Szulczewski, Michael L.; Juanes, Ruben (Elsevier, 2011-04)
    We incorporate CO[subscript 2] dissolution due to convective mixing into a sharp-interface mathematical model for the post-injection migration of a plume of CO[subscript 2] in a saline aquifer. The model captures CO[subscript ...
  • Abanin, D. A.; Song, Justin C. W.; Levitov, Leonid (American Chemical Society (ACS), 2013-07)
    Recent measurements revealed an anomalous Coulomb drag in graphene, hinting at new physics at charge neutrality. The anomalous drag is explained by a new mechanism based on energy transport, which involves interlayer energy ...
