      Understanding the evolution of the human immunodeficiency virus type 1 (HIV-1) envelope during disease progression can provide tremendous insights for vaccine development, and simian-human immunodeficiency virus (SHIV) ...

    • 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 Firm Lobbying 

      Kerr, William Robert; Lincoln, William F.; Mishra, Prachi (American Economic Association, 2014-05-13)
      We study the determinants of the dynamics of firm lobbying behavior using a panel data set covering 1998–2006. Our data exhibit three striking facts: (i) few firms lobby, (ii) lobbying status is strongly associated with ...

    • 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 ...

    • The Dynamics of Hypothalamic Cell Proliferation in Mice 

      Quinan, Virginia C. (2016-10-16)
      Adult neurogenesis is the process by which new neurons are generated by neural stem cells (NSC) and are integrated into existing neural circuits in the adult brain. Contemporary research in adult neurogenesis in mammals ...

    • 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 ...

    • Dynamics of Immune Reconstitution and Activation Markers in HIV+ Treatment-Naïve Patients Treated with Raltegravir, Tenofovir Disoproxil Fumarate and Emtricitabine 

      Funderburg, Nicholas T.; Andrade, Adriana; Chan, Ellen S.; Rosenkranz, Susan L.; Lu, Darlene; Clagett, Brian; Pilch-Cooper, Heather A.; Rodriguez, Benigno; Feinberg, Judith; Daar, Eric; Mellors, John; Kuritzkes, Daniel; Jacobson, Jeffrey M.; Lederman, Michael M. (Public Library of Science, 2013)
      Background: The dynamics of CD4+ T cell reconstitution and changes in immune activation and inflammation in HIV-1 disease following initiation of antiretroviral therapy (ART) are incompletely defined and their underlying ...

    • 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, ...

    • The Dynamics of International Monetary Systems: International and Domestic Factors in the Rise, Reign, and Demise of the Classical Gold Standard 

      Frieden, Jeffry; Snyder, Jack; Jervis, Robert (Westview Press, 1993)

    • 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)
