  • Baumer, Richard E.; Demkowicz, Michael J. (American Physical Society, 2013-04)
    We use molecular dynamics simulations to show that glass transition in a model phase separating amorphous alloy, Cu50Nb50, occurs by gelation. At the glass transition, a mechanically stiff, percolating network of atoms ...
  • Reygers, Klaus; Sanders, Stephen J.; Steinberg, Peter; Miller, Michael L. (Annual Reviews, 2007-05)
    We review the theoretical background, experimental techniques, and phenomenology of what is known in relativistic heavy ion physics as the Glauber model, which is used to calculate geometric quantities. A brief history of ...
  • Liu, Adrian Chi-Yan; Pritchard, Jonathan R.; Tegmark, Max Erik; Loeb, Abraham (American Physical Society, 2013-02)
    The global (i.e., spatially averaged) spectrum of the redshifted 21 cm line has generated much experimental interest lately, thanks to its potential to be a direct probe of the epoch of reionization and the dark ages, ...
  • Andoni, Alexandr; Daskalakis, Constantinos; Hassidim, Avinatan; Roch, Sebastien (Institute for Theoretical Computer Science (ITCS), 2010)
    Molecular phylogenetic techniques do not generally account for such common evolutionary events as site insertions and deletions (known as indels). Instead tree building algorithms and ancestral state inference procedures ...
  • Hurt, Jessica A.; Robertson, Alex De Jong; Burge, Christopher B. (Cold Spring Harbor Laboratory Press, 2013-06)
    UPF1 is a DNA/RNA helicase with essential roles in nonsense-mediated mRNA decay (NMD) and embryonic development. How UPF1 regulates target abundance and the relationship between NMD and embryogenesis are not well understood. ...
  • Aidala, Christine A.; Ellinghaus, Frank; Sassot, Rodolfo; Seele, Joseph Patrick; Stratmann, Marco (American Physical Society, 2011-02)
    Fragmentation functions for eta mesons are extracted at next-to-leading order accuracy of QCD in a global analysis of data taken in electron-positron annihilation and proton-proton scattering experiments. The obtained ...
  • Caballero, J. A.; Gonzalez-Jimenez, R.; Donnelly, T. William (American Physical Society, 2014-08)
    We perform a statistical analysis of the full set of parity-violating asymmetry data for elastic electron scattering including the most recent high precision measurement from Q-weak. Given the basis of the present analysis, ...
  • Saikawa, Eri; Rigby, Matthew; Prinn, Ronald G. (Copernicus GmbH, 2012-11)
    HCFC-22 (CHClF[subscript 2], chlorodifluoromethane) is an ozone-depleting substance (ODS) as well as a significant greenhouse gas (GHG). HCFC-22 has been used widely as a refrigerant fluid in cooling and air-conditioning ...
  • Dlugokencky, E.; Ishijima, K.; Dutton, G. S.; Hall, B. D.; Langenfelds, R.; Tohjima, Y.; Machida, T.; Manizza, M.; Rigby, M.; O'Doherty, S.; Patra, P. K.; Harth, C. M.; Weiss, R. F.; Krummel, P. B.; van der Schoot, M.; Fraser, P. J.; Steele, L. P.; Aoki, S.; Nakazawa, T.; Elkins, J. W.; Saikawa, Eri; Prinn, Ronald G. (Copernicus GmbH, 2014-05)
    We present a comprehensive estimate of nitrous oxide (N[subscript 2]O) emissions using observations and models from 1995 to 2008. High-frequency records of tropospheric N[subscript 2]O are available from measurements at ...
  • O'Doherty, S.; Cunnold, D. M.; Miller, B. R.; Mühle, J.; McCulloch, A.; Simmonds, P. G.; Manning, A. J.; Reimann, S.; Vollmer, M. K.; Greally, B. R.; Fraser, P. J.; Steele, L. P.; Krummel, P. B.; Dunse, B. L.; Porter, L. W.; Lunder, C. R.; Schmidbauer, N.; Hermansen, O.; Salameh, P. K.; Harth, C. M.; Wang, R. H. J.; Weiss, R. F.; Prinn, Ronald G. (American Geophysical Union (AGU), 2009-12)
    High-frequency, in situ observations from the Advanced Global Atmospheric Gases Experiment (AGAGE) and System for Observation of halogenated Greenhouse gases in Europe (SOGE) networks for the period 1998 to 2008, combined ...
  • Kumar, Vijay M. S.; Morrison, David R.; Taylor, Washington (Springer Science + Business Media B.V., 2010-11)
    We develop a systematic framework for realizing general anomaly-free chiral 6D supergravity theories in F-theory. We focus on 6D (1, 0) models with one tensor multiplet whose gauge group is a product of simple factors ...
  • Xu, Yongsheng; Fu, Lee-Lueng; Tulloch, Ross (American Meteorological Society, 2011-08)
    The wavenumber spectra of wind kinetic energy over the ocean from Quick Scatterometer (QuikSCAT) observations have revealed complex spatial variability in the wavelength range of 1000–3000 km, with spectral slopes varying ...
  • Braha, Dan (Public Library of Science, 2012-10)
    Civil unrest is a powerful form of collective human dynamics, which has led to major transitions of societies in modern history. The study of collective human dynamics, including collective aggression, has been the focus ...
  • Censor-Hillel, Keren; Haeupler, Bernhard; Maymounkov, Petar; Kelner, Jonathan Adam (Association for Computing Machinery (ACM), 2012-05)
    In this paper, we study the question of how efficiently a collection of interconnected nodes can perform a global computation in the GOSSIP model of communication. In this model, nodes do not know the global topology of ...
  • Jung, Heekyung; Lacombe, Julie; Mazzoni, Esteban O.; Liem, Karel F., Jr.; Grinstein, Jonathan; Mahony, Shaun; Mukhopadhyay, Debnath; Gifford, David K.; Young, Richard A. (Elsevier, 2010-09)
    In the developing spinal cord, regional and combinatorial activities of Hox transcription factors are critical in controlling motor neuron fates along the rostrocaudal axis, exemplified by the precise pattern of limb ...
  • Slotine, Jean-Jacques E.; Russo, Giovanni (American Physical Society, 2010-10)
    In many natural synchronization phenomena, communication between individual elements occurs not directly but rather through the environment. One of these instances is bacterial quorum sensing, where bacteria release signaling ...
  • Van Damme, M.; Clarisse, L.; Hurtmans, D.; Ngadi, Y.; Clerbaux, C.; Dolman, A. J.; Erisman, J. W.; Coheur, P. F.; Heald, Colette L. (Copernicus GmbH, 2014-03)
    Ammonia (NH[subscript 3]) emissions in the atmosphere have increased substantially over the past decades, largely because of intensive livestock production and use of fertilizers. As a short-lived species, NH[subscript 3] ...
  • Ivy, Diane J.; Rigby, Matthew; Baasandorj, M.; Burkholder, J. B.; Prinn, Ronald G. (Copernicus GmbH, 2012-08)
    Global emission estimates based on new atmospheric observations are presented for the acylic high molecular weight perfluorocarbons (PFCs): decafluorobutane (C[subscript 4]F[subscript 10]), dodecafluoropentane (C[subscript ...
  • Nikurashin, Maxim; Ferrari, Raffaele (American Geophysical Union (AGU), 2011-04)
