  • Yang, Di; Meadows, Mark; Inderwiesen, Phil; Landa, Jorge; Fehler, Michael; Malcolm, Alison E. (Society of Exploration Geophysicists, 2015-09)
    Time-lapse seismic data are widely used to monitor reservoir changes. Qualitative comparisons between baseline and monitor data sets or image volumes provide information about fluid and pressure effects within the reservoir ...
  • Radko, T.; Bulters, A.; Flanagan, J. D.; Campin, Jean-Michel (American Meteorological Society, 2014-05)
    Three-dimensional dynamics of thermohaline staircases are investigated using a series of basin-scale staircase-resolving numerical simulations. The computational domain and forcing fields are chosen to reflect the size and ...
  • Hohm, Olaf; Siegel, Warren; Zwiebach, Barton (Springer-Verlag, 2014-02)
    We develop doubled-coordinate field theory to determine the α ′ corrections to the massless sector of oriented bosonic closed string theory. Our key tool is a string current algebra of free left-handed bosons that makes ...
  • Bonawitz, Elizabeth; Shafto, Patrick; Gweon, Hyowon; Schulz, Laura E.; Goodman, Noah D.; Spelke, Elizabeth (Elsevier B.V., 2011-01)
    Motivated by computational analyses, we look at how teaching affects exploration and discovery. In Experiment 1, we investigated children’s exploratory play after an adult pedagogically demonstrated a function of a toy, ...
  • Schulz, Laura E.; Bonawitz, Elizabeth; Shafto, Patrick; Gweon, Hyowon; Chang, Isabel Y.; Katz, Sydney (Cognitive Science Society, Inc., 2009-07)
    How does explicit instruction affect exploratory play and learning? We present a model that captures pedagogical assumptions (adapted from Shafto and Goodman, 2008) and test the model with a novel experiment looking at ...
  • Hull, Chris; Zwiebach, Barton (IOP Publishing, 2009-09)
    The zero modes of closed strings on a torus — the torus coordinates plus dual coordinates conjugate to winding number — parameterize a doubled torus. In closed string field theory, the string field depends on all zero-modes ...
  • Hohm, Olaf; Zwiebach, Barton (Springer-Verlag, 2014-11)
    We investigate α′ corrections of bosonic strings in the framework of double field theory. The previously introduced “doubled α′-geometry” gives α′-deformed gauge transformations arising in the Green-Schwarz anomaly ...
  • Hohm, Olaf; Kwak, Seung Ki; Zwiebach, Barton (Spring Berlin/Heidelberg, 2011-09)
    We use double field theory to give a unified description of the low energy limits of type IIA and type IIB superstrings. The Ramond-Ramond potentials fit into spinor representations of the duality group O(D, D) and ...
  • Bazant, Martin Z.; Storey, Brian D.; Kornyshe, Alexei A. (American Physical Society, 2011-01)
    We develop a simple Landau-Ginzburg-type continuum theory of solvent-free ionic liquids and use it to predict the structure of the electrical double layer. The model captures overscreening from short-range correlations, ...
  • Hohm, Olaf; Zwiebach, Barton (American Physical Society, 2016-03)
    We relate the unconstrained “double metric” of the “α′-geometry” formulation of double field theory to the constrained generalized metric encoding the spacetime metric and b-field. This is achieved by integrating out ...
  • Ran, F. Ann; Hsu, Patrick D.; Lin, Chie Yu; Gootenberg, Jonathan S.; Konermann, Silvana M.; Trevino, Alexandro E.; Scott, David A.; Inoue, Azusa; Matoba, Shogo; Zhang, Yi; Zhang, Feng; Ran, F. Ann; Scott, David Arthur; Hsu, Patrick D. (Cell Press/Elsevier, 2013-09)
    Targeted genome editing technologies have enabled a broad range of research and medical applications. The Cas9 nuclease from the microbial CRISPR-Cas system is targeted to specific genomic loci by a 20 nt guide sequence, ...
  • Hartman, Jacob M.; Galloway, Duncan K.; Chakrabarty, Deepto (Institute of Physics Publishing, 2011-01)
    The accretion-powered millisecond pulsar IGR J00291+5934 underwent two ~10 day long outbursts during 2008, separated by 30 days in quiescence. Such a short quiescent period between outbursts has never been seen before from ...
  • Zhou, Jigang; Grimaud, Alexis; May, Kevin Joseph; Carlton, Christopher; Lee, Yueh Lin; Risch, Marcel; Hong, Wesley Terrence; Shao-Horn, Yang (Nature Publishing Group, 2013-08)
    The electronic structure of transition metal oxides governs the catalysis of many central reactions for energy storage applications such as oxygen electrocatalysis. Here we exploit the versatility of the perovskite structure ...
  • Janda, F.; Pandharipande, R.; Zvonkine, D.; Pixton, Aaron C (Springer Berlin Heidelberg, 2017-05)
    Curves of genus g which admit a map to P1 with specified ramification profile μ over 0∈P1 and ν over ∞∈P1 define a double ramification cycle DRg(μ,ν) on the moduli space of curves. The study of the restrictions of these ...
  • Guo, Huaihong; Yang, Teng; Yamamoto, Mahito; Zhou, Lin; Ishikawa, Ryo; Ueno, Keiji; Tsukagoshi, Kazuhito; Zhang, Zhidong; Saito, Riichiro; Dresselhaus, Mildred (American Physical Society, 2015-05)
    We study the second-order Raman process of mono- and few-layer MoTe[subscript 2], by combining ab initio density functional perturbation calculations with experimental Raman spectroscopy using 532, 633, and 785 nm excitation ...

R.; Sulkosky, Vincent; Zhan, Xiaohui (American Physical Society, 2015-07)
    We report the measurement of beam-target double spin asymmetries (A[subscript LT]) in the inclusive production of identified hadrons, [→ over e] + [superscript 3]He[superscript ↑] → h + X, using a longitudinally polarized ...

    A lattice quantum chromodynamics (LQCD) calculation of the nuclear matrix element relevant to the nn→ppee[bar over ν]p[subscript e][bar over ν][subscript e] transition is described in detail, expanding on the results ...
  • Liu, Zi-Wen; Perry, Christopher; Zhu, Yechao; Koh, Dax Enshan; Aaronson, Scott (American Physical Society, 2016-01)
    We prove the existence of (one-way) communication tasks with a subconstant versus superconstant asymptotic gap, which we call “doubly infinite,” between their quantum information and communication complexities. We do so ...
  • Ribbeck, Katharina (Elsevier Ltd., 2009-08)
    I propose a mechanism by which viruses successfully infect new individuals, despite being immotile particles with no ability for directed movement. Within cells, viral particle movements are directed by motors and elements ...
  • Zhu, Xiangxin; Ramanan, Deva; Fowlkes, Charless C.; Vondrick, Carl Martin (Springer US, 2015-03)
    Datasets for training object recognition systems are steadily increasing in size. This paper investigates the question of whether existing detectors will continue to improve as data grows, or saturate in performance due ...
