    • The Dynamics of Inequality 

      Gabaix, Xavier; Lasry, Jean-Michel; Lions, Pierre-Louis; Moll, Benjamin (The Econometric Society, 2016)
      The past forty years have seen a rapid rise in top income inequality in the United States. While there is a large number of existing theories of the Pareto tail of the long-run income distributions, almost none of these ...
    • Dynamics of infection, mutation, and eradication, in HIV and other evolving populations 

      Rosenbloom, Daniel Scholes (2013-10-08)
      This work uses mathematical models of evolutionary dynamics to address clinical questions about HIV treatment, public health questions about vaccination, and theoretical questions about evolution of high mutation rates.
    • The Dynamics of Intentions in Collaborative Intentionality 

      Grosz, Barbara; Hunsberger, Luke (Elsevier, 2006)
      An adequate formulation of collective intentionality is crucial for understanding group activity and for modeling the mental state of participants in such activities. Although work on collective intentionality in philosophy, ...
    • Dynamics of Ion Beam Stimulated Surface Mass Transport to Nanopores 

      Hoogerheide, David Paul; Golovchenko, Jene Andrew (Cambridge University Press (CUP), 2007)
      We explore the ion beam-induced dynamics of the formation of large features at the edges of nanopores in freestanding silicon nitride membranes. The shape and size of these ìnanovolcanoesî, together with the rate at which ...
    • Dynamics of Long-lived Foundation Species: The History of Quercus in Southern Scandinavia 

      Lindbladh, Matts; Foster, David Russell (Wiley-Blackwell, 2010)
      (1) The long-term history of Quercus in southern Scandinavia has received little attention despite its important role in modern conservation. In this study the 4000-year dynamics of Quercus, its habitat and other important ...
    • Dynamics of Mechanosensing in the Bacterial Flagellar Motor 

      Lele, Pushkar Prakash; Hosu, Basarab Gabriel; Berg, Howard Curtis (Proceedings of the National Academy of Sciences, 2013)
      Mechanosensing by flagella is thought to trigger bacterial swarmer-cell differentiation, an important step in pathogenesis. How flagellar motors sense mechanical stimuli is not known. To study this problem, we suddenly ...
    • Dynamics of Neural Activity During Chemotaxis in Caenorhabditis Elegans 

      Shen, Ching-Han (2015-09-28)
      The nervous system of an animal must control and coordinate locomotion in a changing and often unpredictable environment in order to survive. When a Caenorhabditis elegans navigates its environment, the nervous system can ...
    • Dynamics of Oligomer Populations Formed During the Aggregation of Alzheimer’s Aβ42 Peptide 

      Michaels, Thomas; Saric, Andela; Curk, Samo; Bernfur, Katja; Arosio, Paolo; Meisl, Georg; Dear, Alexander J; Cohen, Samuel I A; Dobson, Christopher M; Vendruscolo, Michele; Linse, Sara; Knowles, Tuomas P J; Knowles (Cold Spring Harbor Laboratory, 2020-04-13)
      Oligomeric aggregates populated during the aggregation of the Aβ42 peptide have been identified as potent cytotoxins linked to Alzheimer's disease, but the fundamental molecular pathways that control their dynamics have ...
    • Dynamics of One-dimensional Bose Liquids: Andreev-like Reflection at Y-junctions and Absence of the Aharonov-Bohm Effect 

      Tokuno, Akiyuki; Oshikawa, Masaki; Demler, Eugene A. (American Physical Society, 2008)
      We study one dimensional Bose liquids of interacting ultracold atoms in the Y-shaped potential when each branch is filled with atoms. We find that the excitation packet incident on a single Y-junction should experience a ...
    • Dynamics of p53 tetramers in live single cells 

      Gaglia, Giorgio (2014-06-06)
      Protein homo-oligomerization is the process through which identical peptides bind together to form higher order complexes. Self-interactions in many cases are constitutive and stable, used as building blocks for biological ...
    • Dynamics of Pattern Formation During Low-Energy Ion Bombardment of Si(0 0 1) 

      Chason, Eric; Erlebacher, Jonah; Aziz, Michael; Floro, Jerry A.; Sinclair, Michael B. (Elsevier Science B.V., Amsterdam, 2001)
      Sputtering of surfaces by collimated, low-energy ion beams results in spontaneous pattern formation in many systems. In order to explore the mechanisms that control the pattern formation, we have used in situ light scattering ...
    • Dynamics of prebiotic RNA reproduction illuminated by chemical game theory 

      Yeates, Jessica A. M.; Hilbe, Christian; Zwick, Martin; Nowak, Martin A.; Lehman, Niles (Proceedings of the National Academy of Sciences, 2016)
      Many origins-of-life scenarios depict a situation in which there are common and potentially scarce resources needed by molecules that compete for survival and reproduction. The dynamics of RNA assembly in a complex mixture ...
    • Dynamics of protein evolution within complex biophysical constraints 

      Gilson, Amy I. (2017-03-03)
      Proteins evolve within complex biophysical constraints. Natural selection promotes the survival of the fittest organisms. Therefore, protein variants that decrease organismal fitness are likely to go extinct along with the ...
    • Dynamics of Q-switched laser annealing 

      Auston, D. H.; Golovchenko, Jene Andrew; Simons, A. L.; Surko, C. M.; Venkatesan, T. N. C. (AIP Publishing, 1979)
      Using time‐resolved optical‐reflectivity measurements, the duration of the thin liquid layer accompanying Q‐switched laser annealing in Si, Ge, and GaAs has been determined. The duration of this melted layer has been studied ...
    • The Dynamics of Quantum Criticality Revealed by Quantum Monte Carlo and Holography 

      Witczak-Krempa, William; Sørensen, Erik S.; Sachdev, Subir (Nature Publishing Group, 2014)
      Understanding the dynamics of quantum systems without long-lived excitations (quasiparticles) constitutes an important yet challenging problem. Although numerical techniques can yield results for the dynamics in imaginary ...
    • Dynamics of SL2(ℝ) Over Moduli Space in Genus Two 

      McMullen, Curtis T. (Princeton University, 2007)
      This paper classifies orbit closures and invariant measures for the natural action of SL2(ℝ) on Ωℳ2, the bundle of holomorphic 1-forms over the moduli space of Riemann surfaces of genus two.
