    • Dynamics of a Floating Exchange Rate Regime 

      Helpman, Elhanan; Razin, Assaf (University of Chicago Press, 1982)
      We study the full equilibrium dynamics of a two-country world economy with a floating exchange rate, traded and nontraded goods, and explicit modeling of the use of money. The resulting exchange rate equation depends on ...

    • Dynamics of a Massive Black Hole at the Center of a Dense Stellar System 

      Chatterjee, Pinaki; Hernquist, Lars; Loeb, Abraham (American Astronomical Society, 2002)
      We develop a simple physical model to describe the dynamics of a massive pointlike object, such as a black hole, near the center of a dense stellar system. It is shown that the total force on this body can be separated ...

    • Dynamics of a Snowball Earth Ocean 

      Ashkenazy, Yosef; Gildor, Hezi; Losch, Martin; Macdonald, Francis Alexander; Schrag, Daniel P.; Tziperman, Eli (Nature Publishing Group, 2013)
      Geological evidence suggests that marine ice extended to the Equator at least twice during the Neoproterozoic era (about 750 to 635 million years ago), inspiring the Snowball Earth hypothesis that the Earth was globally ...

    • Dynamics of Algorithmic Fairness 

      Hu, Lily (2022-05-11)
      The rise of machine learning-based predictive models in making decisions of profound social impact has spurred study of those technical properties that may bear on the moral and political character of their deployment. One ...

    • Dynamics of Astrophysical Bubbles and Bubble-driven Shocks: Basic Theory, Analytical Solutions, and Observational Signatures 

      Medvedev, Mikhail V.; Loeb, Abraham (American Astronomical Society, 2013)
      Bubbles in the interstellar medium are produced by astrophysical sources, which continuously or explosively deposit large amounts of energy into the ambient medium. These expanding bubbles can drive shocks in front of them, ...

    • Dynamics of Bacterial Swarming 

      Darnton, Nicholas C.; Turner, Linda; Rojevsky, Svetlana; Berg, Howard Curtis (Biophysical Society, 2010)
      When vegetative bacteria that can swim are grown in a rich medium on an agar surface, they become multinucleate, elongate, synthesize large numbers of flagella, produce wetting agents, and move across the surface in ...

    • Dynamics of Carbon, Biomass, and Structure in Two Amazonian Forests 

      Pyle, Elizabeth Hammond; Santoni, Gregory Winn; Nascimento, Henrique E. M.; Hutyra, Lucy R.; Vieira, Simone; Curran, Daniel J.; van Haren, Joost; Saleska, Scott R.; Chow, Victoria Ye; Carmago, Plinio B.; Laurance, William; Wofsy, Steven C. (American Geophysical Union, 2008)
      Amazon forests are potentially globally significant sources or sinks for atmospheric carbon dioxide. In this study, we characterize the spatial trends in carbon storage and fluxes in both live and dead biomass (necromass) ...

    • Dynamics of Charged Colloids in Nonpolar Solvents 

      Lin, Tina (2013-09-04)
      Charging is typically not expected in nonpolar environments due to a high electrostatic barrier to charge dissociation. Nevertheless, charge effects are observed in such environments upon the addition of surfactants, which ...

    • Dynamics of Convectively Driven Banded Jets in the Laboratory 

      Read, Peter L.; Yamazaki, Yasuhiro H.; Lewis, Stephen R.; Williams, Paul D.; Wordsworth, Robin; Miki-Yamazaki, Kuniko; Sommeria, Joël; Didelle, Henri (American Meteorological Society, 2007)
      The banded organization of clouds and zonal winds in the atmospheres of the outer planets has long fascinated observers. Several recent studies in the theory and idealized modeling of geostrophic turbulence have suggested ...

    • Dynamics of Cortical Decision Circuits during Changes in the Fidelity of Sensory Representations 

      Smolyanskaya, Alexandra (2012-10-23)
      Every waking moment, we make decisions, from where to move our eyes to what to eat for dinner. The ease and speed with which we do this belie the complexity of the underlying neuronal processing. In the visual system, every ...

    • The Dynamics of Dense Cores in the Perseus Molecular Cloud II: the Relationship between Dense Cores and the Cloud 

      Kirk, Helen; Pineda, Jaime E.; Johnstone, Doug; Goodman, Alyssa (Institute of Physics Publishing, Inc., 2010)
      We utilize the extensive datasets available for the Perseus molecular cloud to analyze the relationship between the kinematics of small-scale dense cores and the larger structures in which they are embedded. The kinematic ...

    • Dynamics of Drying in 3D Porous Media 

      Xu, Lei; Davies, Simon; Schofield, Andrew B.; Weitz, David A. (American Physical Society, 2008)
      The drying dynamics in three dimensional porous media are studied with confocal microscopy. We observe abrupt air invasions in size from single particle to hundreds of particles. We show that these result from the strong ...

    • Dynamics of evaporative colloidal patterning 

      Kaplan, Cihan Nadir; Wu, Ning; Mandre, Shreyas; Aizenberg, Joanna; Mahadevan, Lakshminarayanan (AIP Publishing, 2015)
      Drying suspensions often leave behind complex patterns of particulates, as might be seen in the coffee stains on a table. Here, we consider the dynamics of periodic band or uniform solid film formation on a vertical plate ...

    • The Dynamics of Genetic Draft in Rapidly Adapting Populations 

      Kosheleva, Katya; Desai, Michael Manish (Genetics Society of America, 2013)
      The accumulation of beneficial mutations on competing genetic backgrounds in rapidly adapting populations has a striking impact on evolutionary dynamics. This effect, known as clonal interference, causes erratic fluctuations ...

    • The dynamics of global risks: Sociopolitical risks in strategic management and policy decisions 

      Marolla, Cesar (De Gruyter, 2023-04-12)
      The development of the risk landscape has shifted significantly in recent years. The magnitude and consequence of more varied risks than ever previously experienced create new hazards, and exacerbate existing ones. Global ...

    • Dynamics of goat distal hind limb muscle-tendon function in response to locomotor grade 

      McGuigan, M. P.; Yoo, E.; Lee, D. V.; Biewener, Andrew Austin (The Company of Biologists, 2009)
      The functional roles of the lateral gastrocnemius (LG), medial gastrocnemius (MG) and superficial digital flexor (SDF) muscle–tendon units (MTUs) in domestic goats (N=6) were studied as a function of locomotor grade, testing ...

    • Dynamics of HIV treatment and social contagion 

      Hill, Alison Lynn (2013-10-08)
      Modern-day management of infectious diseases is critically linked to the use of mathematical models to understand and predict dynamics at many levels, from the mechanisms of pathogenesis to the patterns of population-wide ...

    • Dynamics of ice stream temporal variability: Modes, scales, and hysteresis 

      Robel, Alexander Abram; DeGiuli, E.; Schoof, C.; Tziperman, Eli (Wiley-Blackwell, 2013)
      Understanding the mechanisms governing temporal variability of ice stream flow remains one of the major barriers to developing accurate models of ice sheet dynamics and ice‒climate interactions. Here we analyze a simple ...

    • 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 ...

      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.
