  • 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, ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Siegel, Susanna; Hilbert, David; Byrne, Alex (Cambridge University Press, 2007-12)
    One of Block's conclusions, motivated by partial-report superiority experiments, is that there is phenomenally conscious information that is not cognitively accessible. We argue that this conclusion is not supported by the data.
  • Emanuel, Kerry Andrew (National Academy of Sciences (U.S.), 2013-07)
    A recently developed technique for simulating large [O(10[superscript 4])] numbers of tropical cyclones in climate states described by global gridded data is applied to simulations of historical and future climate states ...
  • Gibson, Joanne H; Slobedman, Barry; Kn, Harikrishnan; Williamson, Sarah L; Minchenko, Dimitri; El-Osta, Assam; Stern, Joshua L; Christodoulou, John (BioMed Central Ltd, 2010-04)
    Background: The Rett Syndrome (RTT) brain displays regional histopathology and volumetric reduction, with frontal cortex showing such abnormalities, whereas the occipital cortex is relatively less affected. Results: Using ...
  • Bortvin, Alex; Goodheart, Mary; Liao, Michelle; Page, David C. (BioMed Central Ltd, 2004-02)
    Background: In mice, germ cells are specified through signalling between layers of cells comprising the primitive embryo. The function of Dppa3 (also known as Pgc7 or stella), a gene expressed in primordial germ cells at ...
  • Keeley, Charlotte N.; Ducuing, Antoine; Mollereau, Bertrand; Vincent, Stephane (Rockefeller University Press, 2015-01)
    Development is robust because nature has selected various mechanisms to buffer the deleterious effects of environmental and genetic variations to deliver phenotypic stability. Robustness relies on smart network motifs such ...
  • Grote, Jana; Bayindirli, Cansu; Bergauer, Kristin; Carpintero de Moraes, Paula; Chen, Huan; D’Ambrosio, Lindsay; Edwards, Bethanie; Fernandez-Gomez, Beatriz; Hamisi, Mariam; Logares, Ramiro; Nguyen, Dan; Rii, Yoshimi M.; Saeck, Emily; Schutte, Charles; Widner, Brittany; Church, Matthew J.; Steward, Grieg F.; Karl, David M.; DeLong, Edward; Eppley, John Marmaduke; Schuster, Stephan C.; Kyrpides, Nikos C.; Rappe, Michael S. (Genomic Standards Consortium, 2011)
    Strain HIMB100 is a planktonic marine bacterium in the class Alphaproteobacteria. This strain is of interest because it is one of the first known isolates from a globally ubiquitous clade of marine bacteria known as SAR116 ...
  • Sheh, Alexander; Shen, Zeli; Fox, James G. (American Society for Microbiology, 2014-11)
    The draft genome sequences of eight enterohepatic Helicobacter species, H. muridarum, H. trogontum, H. typhlonius, and five unnamed helicobacters, are presented here. Using laboratory mice pervasively infected with ...
  • Sheh, Alexander; Piazuelo, M. Blanca; Wilson, Keith T.; Correa, Pelayo; Fox, James G. (American Society for Microbiology, 2013-09)
    The draft genome sequences of six Colombian Helicobacter pylori strains are presented. These strains were isolated from patients from regions of high and low gastric cancer risk in Colombia and were characterized by ...
  • Shen, Zeli; Sheh, Alexander; Young, Sarah K.; Amr Abouelliel (American Society for Microbiology, 2014-09)
    Draft genome sequences of seven enterohepatic Helicobacter species, H. bilis, H. canadensis, H. canis, H. cinaedi, H. winghamensis, H. pullorum, and H. macacae, are presented. These isolates were obtained from clinical ...
  • Peet, Kyle Creighton; Thompson, Janelle Renee (American Society for Microbiology, 2015-04)
    We report draft genome sequences of Bacillus subterraneus MITOT1 and Bacillus cereus MIT0214 isolated through enrichment of samples from geologic sequestration sites in pressurized bioreactors containing a supercritical ...
  • Wang, Qiqi; Gao, Jun-Hui (Cambridge University Press, 2013-07)
    This paper analyses the adjoint solution of the Navier–Stokes equation. We focus on flow across a circular cylinder at three Reynolds numbers, Re[subscript D] = 20,100 and 500. The quantity of interest in the adjoint ...
  • Srinivasan, Siddarth; Choi, Wonjae; Park, Kyoo-Chul; Chhatre, Shreerang Sharad; Cohen, Robert E.; McKinley, Gareth H.; Park, Kyoo Chul (Royal Society of Chemistry, 2013)
    We estimate the effective Navier-slip length for flow over a spray-fabricated liquid-repellent surface which supports a composite solid–air–liquid interface or ‘Cassie–Baxter’ state. The morphology of the coated substrate ...
