  • Deschênes, Olivier; Greenstone, Michael (American Economic Association, 2012-12)
    Fisher et al. (2012) (hearafter, FHRS) have uncovered coding and data errors in our paper, Deschênes and Greenstone (2007), henceforth, DG. We acknowledge and are embarrassed by these mistakes. We are grateful to FHRS for ...
  • Mistry, Karan Hemant; Lienhard, John H. (MDPI AG, 2013-07)
    Second Law efficiency is a useful parameter for characterizing the energy requirements of a system in relation to the limits of performance prescribed by the Laws of Thermodynamics. However, since energy costs typically ...
  • Acemoglu, Daron; Wolitzky, Alexander G. (Econometric Society, 2011-02)
    The majority of labor transactions throughout much of history and a significant fraction of such transactions in many developing countries today are “coercive,” in the sense that force or the threat of force plays a central ...
  • Marx, Benjamin; Stoker, Thomas Martin; Suri, Tavneet (American Economic Association, 2013-11)
    The global expansion of urban slums poses questions for economic research as well as problems for policymakers. We provide evidence that the type of poverty observed in contemporary slums of the developing world is ...
  • Acemoglu, Daron; Robinson, James A (American Economic Association, 2013-02)
    The standard approach to policy making and advice in economics implicitly or explicitly ignores politics and political economy and maintains that if possible, any market failure should be rapidly removed. This essay explains ...
  • Meredith, Laura Kelsey; Commane, R.; Munger, J. W.; Dunn, A.; Tang, J.; Wofsy, S. C.; Prinn, Ronald G. (Copernicus GmbH on behalf of the European Geosciences Union, 2014-09)
    Our understanding of biosphere–atmosphere exchange has been considerably enhanced by eddy covariance measurements. However, there remain many trace gases, such as molecular hydrogen (H[subscript 2]), that lack suitable ...
  • Gong, Zheng; Tran, Duong; Yi, Dong Hoon; Wu, Fan; Zorn, Alexander; Ratilal, Purnima; Jain, Ankita Deepak; Makris, Nicholas (Public Library of Science, 2014-10)
    We show that humpback-whale vocalization behavior is synchronous with peak annual Atlantic herring spawning processes in the Gulf of Maine. With a passive, wide-aperture, densely-sampled, coherent hydrophone array towed ...
  • Coleman, Maureen L.; Chisholm, Sallie (Penny) (National Academy of Sciences (U.S.), 2010-10)
    Bacterial populations harbor vast genetic diversity that is continually shaped by abiotic and biotic selective pressures, as well as by neutral processes. Individuals coexisting in the same geographically defined population ...
  • Ferrari, Raffaele; Fox-Kemper, Baylor (American Meteorological Society, 2009-06)
    The time-mean effects of eddies are studied in a model based on the Parsons–Veronis–Huang–Flierl models of the wind-driven gyre. Much of the analysis used for the steady solutions carries over if the model is cast in terms ...
  • Min, K.-E.; Pusede, S. E.; Browne, Eleanor C.; LaFranchi, B. W.; Cohen, R. C. (Copernicus GmbH on behalf of the European Geosciences Union, 2014-06)
    Exchange of NO[subscript x] (NO+NO[subscript 2]) between the atmosphere and biosphere is important for air quality, climate change, and ecosystem nutrient dynamics. There are few direct ecosystem-scale measurements of the ...
  • Velasco, Erik; Pressley, S.; Grivicke, R.; Allwine, E.; Coons, T.; Foster, W.; Jobson, T.; Westberg, H.; Ramos, R.; Hernandez, F.; Molina, Luisa Tan; Lamb, B. (European Geosciences Union / Copernicus, 2009-10)
    Eddy covariance (EC) flux measurements of the atmosphere/surface exchange of gases over an urban area are a direct way to improve and evaluate emissions inventories, and, in turn, to better understand urban atmospheric ...
  • Waterman, Stephanie; Jayne, Steven R. (American Meteorological Society, 2012-03)
    The generation of time-mean recirculation gyres from the nonlinear rectification of an oscillatory, spatially localized vorticity forcing is examined analytically and numerically. Insights into the rectification mechanism ...
  • Waterman, Stephanie; Jayne, Steven R. (© 2011 American Meteorological Society, 2010-12)
    A theoretical study on the role of eddy-mean flow interactions in the time-mean dynamics of a zonally evolving, unstable, strongly inertial jet in a configuration and parameter regime that is relevant to oceanic western ...
  • Ferrari, Raffaele; Boccaletti, Giulio (The Oceanography Society, 2004-09)
    The oceanic surface mixed layer is where communication takes place between the oceanic reservoir of heat, freshwater, and carbon dioxide, and the overlying atmosphere in which we live. The exchange of properties and their ...
  • Mazloff, Matthew R.; Heimbach, Patrick; Wunsch, Carl (American Meteorological Society, 2010-05)
    An eddy-permitting general circulation model of the Southern Ocean is fit by constrained least squares to a large observational dataset during 2005–06. Data used include Argo float profiles, CTD synoptic sections, Southern ...
  • Ferrari, Raffaele; Garabato, A. C. Naveira; Polzin, K. L. (American Geophysical Union (AGU), 2011-09)
    There is an ongoing debate concerning the distribution of eddy stirring across the Antarctic Circumpolar Current (ACC) and the nature of its controlling processes. The problem is addressed here by estimating the isentropic ...
  • Cerovecki, Ivana; Plumb, R. Alan; Heres, William (American Meteorological Society, 2009-05)
    The baroclinically unstable wind- and buoyancy-driven flow in a zonally reentrant pie-shaped sector on a sphere is numerically modeled and then analyzed using the transformed Eulerian-mean (TEM) formalism. Mean fields are ...
  • Hubbard, Amanda E.; Whyte, Dennis G.; Churchill, Randy Michael; Cziegler, Istvan; Golfinopoulos, Theodore; Hughes, Jerry W.; Rice, John E.; Bespamyatnov, I.; Greenwald, Martin J.; Howard, Nathaniel Thomas; Lipschultz, Bruce; Marmar, Earl S.; Reinke, Matthew Logan; Rowan, W. L.; Terry, James L.; Alcator C-Mod Group (American Institute of Physics, 2011-05)
    We report extended studies of the I-mode regime [Whyte et al., Nucl. Fusion 50, 105005 (2010)] obtained in the Alcator C-Mod tokamak [Marmar et al., Fusion Sci. Technol. 51(3), 3261 (2007)]. This regime, usually accessed ...
  • Potter, Andrew C.; Lee, Patrick A. (American Physical Society, 2014-03)
    In mean-field descriptions of nodal d-wave superconductors, generic edges exhibit dispersionless Majorana fermion bands at zero energy. These states give rise to an extensive ground-state degeneracy, and are protected by ...
  • Subr, Kartic; Soler, Cyril; Durand, Fredo (Association for Computing Machinery (ACM), 2009)
    We propose a new model for detail that inherently captures oscillations, a key property that distinguishes textures from individual edges. Inspired by techniques in empirical data analysis and morphological image analysis, ...
