  • Sing, Charles E.; Alexander-Katz, Alfredo (American Institute of Physics, 2011-07)
    Collapsed polymers in solution represent an oft-overlooked area of polymer physics, however recent studies of biopolymers in the bloodstream have suggested that the physics of polymer globules are not only relevant but ...
  • Hidalgo, Juan J.; MacMinn, Christopher W.; Juanes, Ruben (Elsevier, 2013-07)
    During geologic storage of carbon dioxide (CO[subscript 2]), trapping of the buoyant CO[subscript 2] after injection is essential in order to minimize the risk of leakage into shallower formations through a fracture or ...
  • Jung, Sunghwan; Winter, Amos; Hosoi, Anette E. (Elsevier B.V., 2011-05)
    Numerous animals live in, and locomote through, subsea soils. To move in a medium dominated by frictional interactions, many of these animals have adopted unique burrowing strategies. This paper presents a burrowing model ...
  • Sander, Michelle Yen-Ling; Birge, Jonathan R.; Benedick, Andrew J.; Crespo, Helder M.; Kaertner, Franz X. (Optical Society of America, 2009-03)
    An extensive one-dimensional laser model based on dispersion managed mode locking is presented that accurately describes the pulse dynamics of octave-spanning titanium:sapphire lasers generating sub-two-cycle pulses. By ...
  • Kerr, Catherine E.; Hamalainen, Matti S.; Jones, Stephanie R.; Wan, Qian; Pritchett, Dominique Leon; Moore, Christopher I. (Public Library of Science, 2011-09)
    Background Behavioral paradigms applied during human recordings in electro- and magneto- encephalography (EEG and MEG) typically require 1–2 hours of data collection. Over this time scale, the natural fluctuations in ...
  • Acemoglu, Daron; Bimpikis, Kostas; Ozdaglar, Asuman E. (The Econometric Society, 2014-01)
    We develop a model of information exchange through communication and investigate its implications for information aggregation in large societies. An underlying state determines payoffs from different actions. Agents decide ...
  • Isik, Leyla; Meyers, Ethan M.; Leibo, Joel Z.; Poggio, Tomaso A. (American Physiological Society, 2013-10)
    The human visual system can rapidly recognize objects despite transformations that alter their appearance. The precise timing of when the brain computes neural representations that are invariant to particular transformations, ...
  • Bustos, Sebastian; Gomez, Charles; Hausmann, Ricardo; Hidalgo, Cesar A. (Public Library of Science, 2012-11)
    In economic systems, the mix of products that countries make or export has been shown to be a strong leading indicator of economic growth. Hence, methods to characterize and predict the structure of the network connecting ...
  • Skow, Bradford (Scholarly Publishing Office, University of Michigan Library, 2010-01)
    Maybe there is something rather than nothing because the nothingness force acted on itself, and when the nothing nothings itself it produces something. Robert Nozick suggested this as a candidate explanation of the fact ...
  • Athey, Susan; Ellison, Glenn (Wiley Blackwell, 2014-04)
    This paper considers a dynamic model of the evolution of open-source software projects, focusing on the evolution of quality, contributing programmers, and users who contribute customer support to other users. Programmers ...
  • Chen, Hsieh; Alexander-Katz, Alfredo (American Physical Society (APS), 2011-09)
    Using hydrodynamic simulations we examine the behavior of single polymers in a confined colloidal suspension under flow. We study the conformations of both, collapsed and noncollapsed polymers. Our results show that the ...
  • Ghoshal, Gourab; Blumm, Nicholas; Forro, Zalan; Schich, Maximilian; Bianconi, Ginestra; Bouchaud, Jean-Philippe; Barabasi, Albert-Laszlo (American Physical Society, 2012-09)
    The world is addicted to ranking: everything, from the reputation of scientists, journals, and universities to purchasing decisions is driven by measured or perceived differences between them. Here, we analyze empirical ...
  • Rapoport, Elizabeth Ashera; Beach, Geoffrey Stephen (American Institute of Physics (AIP), 2012-02)
    The dynamics of fluid-borne superparamagnetic bead transport by field-driven domain walls in submicrometer ferromagnetic tracks is studied experimentally together with numerical and analytical modeling. Experiments show ...
  • Veysset, David Georges; Hsieh, Alex J.; Kooi, Steven E.; Maznev, Alexei; Masser, Kevin A.; Nelson, Keith Adam (Springer Nature, 2016-05)
    Understanding high–velocity microparticle impact is essential for many fields, from space exploration to medicine and biology. Investigations of microscale impact have hitherto been limited to post–mortem analysis of ...
  • Wu, Weisheng; Cheng, Yong; Keller, Cheryl A.; Ernst, Jason; Kumar, Swathi Ashok; Mishra, Tejaswini; Morrissey, Christapher; Dorman, Christine M.; Chen, Kuan-Bei; Drautz, Daniela; Giardine, Belinda; Shibata, Yoichiro; Song, Lingyun; Pimkin, Max; Crawford, Gregory E.; Furey, Terrence S.; Kellis, Manolis; Miller, Webb; Taylor, James; Schuster, Stephan C.; Zhang, Yu; Chiaromonte, Francesca; Blobel, Gerd A.; Weiss, Mitchell J.; Hardison, Ross C. (Cold Spring Harbor Laboratory Press, 2011-07)
    Interplays among lineage-specific nuclear proteins, chromatin modifying enzymes, and the basal transcription machinery govern cellular differentiation, but their dynamics of action and coordination with transcriptional ...
  • Kingsbery, James; Levin, Alexander; Preygel, Anatoly; Silva, Cesar E. (American Institute of Mathematical Sciences, 2011-02)
    There is a natural continuous realization of the one-sided Bernoulli shift on the [p] -adic integers as the map that shifts the coefficients of the [p] -adic expansion to the left. We study this map's Mahler power series ...
  • Laub, Michael T.; Chen, Y. Erin; Tsokos, Christos G.; Biondi, Emanuele G.; Perchuk, Barrett (American Society for Microbiology, 2009-09)
    In Caulobacter crescentus, progression through the cell cycle is governed by the periodic activation and inactivation of the master regulator CtrA. Two phosphorelays, each initiating with the histidine kinase CckA, ...
  • Graham, Michael D.; Xi, Li (American Physical Society, 2012-01)
    Dynamical trajectories on the boundary in state space between laminar and turbulent plane channel flow—edge states—are computed for Newtonian and viscoelastic fluids. Viscoelasticity has a negligible effect on the properties ...
  • Schepers, Winfried; Savidis, Stavros; Kausel, Eduardo A. (Elsevier, 2010-01)
    This paper deals with the problem of time-varying point loads applied onto the surface of an elastic half-space and the stresses that such loads elicit within that medium. The emphasis is on the evaluation of the isobaric ...
  • Zhang, Yang; Lagi, Marco; Fratini, Emiliano; Baglioni, Piero; Mamontov, Eugene; Chen, Sow-Hsin (American Physical Society, 2009-04)
    We study the dynamic susceptibility χT(Q,t) of deeply supercooled water by means of quasielastic neutron scattering and molecular dynamics simulations. Both techniques show an increase in the peak height of χT(Q,t) as the ...
