  • Keast, Craig L.; Wyatt, Peter W.; Kong, Jing; Reina, Alfonso; Hsu, Pei-Lan; Healey, Paul D.; Kedzierski, Jakub T. (Institute of Electrical and Electronics Engineers, 2009-06)
    Graphene transistors are made by transferring a thin graphene film grown on Ni onto an insulating SiO[subscript 2] substrate. The properties and integration of these graphene-on-insulator transistors are presented and ...
  • Swager, Timothy Manning; Schmois, Ezequiel; Collins, William R. (Royal Society of Chemistry, 2011-07)
    The covalent, surface functionalization of graphene oxide with the malononitrile anion has been demonstrated. Once installed, these surface-bound “molecular lynchpins” can be chemically modified to increase the solubility ...
  • Mazumder, Rahul; Hastie, Trevor (Institute of Mathematical Statistics, 2012)
    The graphical lasso [5] is an algorithm for learning the structure in an undirected Gaussian graphical model, using ℓ[subscript 1] regularization to control the number of zeros in the precision matrix Θ = Σ[superscript −1] ...
  • Vona, Marsette A. (Institute of Electrical and Electronics Engineers (IEEE), 2010-04)
    This paper presents the design and implementation of algorithms for a new graphical operations interface system specifically adapted to operating modular reconfigurable articulated surface systems. Geometric models of ...
  • Kleindienst, Siân; Bodart, Magali; Andersen, Marilyne (Illuminating Engineering Society of North America, 2008-07)
    Many conventional daylighting design tools are limited in that each simulation represents only one time of year and time of day (or a single, theoretical overcast sky condition). Since daylight is so variable – due to the ...
  • Blanchard, R.; Menzel, S.; Pflugl, C.; Diehl, L.; Wang, Christine A.; Huang, Y.; Ryou, J.-H.; Dupuis, R. D.; Negro, L. Dal; Capasso, F. (Institute of Physics Publishing, 2011-11)
    We propose a new class of gratings having multiple spatial frequencies. Their design relies on the use of small aperiodic grating sequences as unit cells whose repetition forms a superlattice. The superlattice provides ...
  • Kaspi, Yohai; Hubbard, William B.; Showman, Adam P.; Flierl, Glenn Richard (American Geophysical Union (AGU), 2010-01)
    Telescopic observations and space missions to Jupiter have provided vast information about Jupiter's cloud level winds, but the depth to which these winds penetrate has remained an ongoing mystery. Scheduled to be launched ...
  • Regimbau, T.; Hughes, Scott A. (American Physical Society, 2009-03)
    Increasing the sensitivity of a gravitational-wave (GW) detector improves our ability to measure the characteristics of detected sources. It also increases the number of weak signals that contribute to the data. Because ...
  • Hughes, Scott A. (Annual Reviews, 2009-09)
    Largely motivated by the development of highly sensitive gravitational-wave detectors, our understanding of merging compact binaries and the gravitational waves they generate has improved dramatically in recent years. ...
  • Yunes, Nicolas; Cornish, Neil; Sampson, Laura; Pretorius, Frans (American Physical Society (APS), 2011-09)
    Gravitational wave astronomy has tremendous potential for studying extreme astrophysical phenomena and exploring fundamental physics. The waves produced by binary black hole mergers will provide a pristine environment in ...
  • Diorio, James; Cho, Yeunwoo; Duncan, James H.; Akylas, Triantaphyllos R. (American Physical Society, 2009-09)
    The nonlinear wave pattern generated by a localized pressure source moving over a liquid free surface at speeds below the minimum phase speed (c [subscript min]) of linear gravity-capillary waves is investigated experimentally ...
  • Tanino, Yukie; Nepf, Heidi; Kulis, P. S. (American Geophysical Union, 2005-12)
    A lock exchange experiment is used to investigate the propagation of gravity currents through a random array of rigid, emergent cylinders which represents a canopy of aquatic plants. As canopy drag increases, the propagating ...
  • McGreevy, John; Balasubramanian, Koushik (American Physical Society, 2008-08)
    We attempt to generalize the anti–de Sitter/conformal field theory correspondence to nonrelativistic conformal field theories which are invariant under Galilean transformations. Such systems govern ultracold atoms at ...
  • Temin, Peter (MIT Press, 2010-10)
    In the depths of the Great Depression, John Maynard Keynes wrote that “[p]racticalmen, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist.”1 ...
  • Beck, Matthias; Haase, Christian; Sam, Steven V. (Springer Science + Business Media B.V., 2009-02)
    We examine domino tilings of rectangular boards, which are in natural bijection with perfect matchings of grid graphs. This leads to the study of their associated perfect matching polytopes, and we present some of their ...
  • Schmalensee, Richard; Heidel, Timothy D.; Kassakian, John G. (Public Utilities Reports Inc., 2012-01)
    A few years ago, former Secretary of Energy Bill Richardson characterized the U.S. electric grid, the system of physical and human systems linking generators to loads, as “third-world.” 1 More recently, others have claimed ...
  • Rodi, William L. (Elsevier, 2006-06)
    This study employs an event location algorithm based on grid search to investigate the possibility of improving seismic event location accuracy by using non-Gaussian error models. The primary departure from the Gaussian ...
  • Chen, Gang; Lan, Yucheng; Wang, Hui; Ren, Zhifeng; Wang, Dezhi (Hindawi Pub. Corp., 2010-06)
    New TEM grids coated with ultrathin amorphous Al2O3 films have been developed using atomic layer deposition technique. The amorphous Al2O3 films can withstand temperatures over 600∘C in air and 900∘C in vacuum when the ...
  • Levin, Z.; Ardon Dryer, Karin (Copernicus GmbH, 2014-05)
    Ice nuclei were measured in immersion-freezing mode in the eastern Mediterranean region using the FRIDGE-TAU (FRankfurt Ice-nuclei Deposition freezinG Experiment, the Tel Aviv University version) chamber. Aerosol particles ...

C.; Bouchy, F.; Cabrera-Lavers, A.; Cerutti, S.; Coban, L.; Costello, K.; Deeg, H.; Diaz, R. F.; Esquerdo, G. A.; Fernandez, J.; Fleming, S. W.; Ford, E. B.; Fulton, B.

R.; Ruth, R.; Simpson, E.; Vincent, C.; Weaver, G.; Xie, J. W. (IOP Publishing, 2010-09)
    We present ground-based optical observations of the 2009 September and 2010 January transits of HD 80606b. Based on three partial light curves of the 2009 September event, we derive a midtransit time of Tc [HJD] = 2455099.196 ...
