  • Rajimehr, Reza; Tootell, Roger B. H. (Society for Neuroscience, 2009-09)
    In humans and other Old World primates, much of visual cortex comprises a set of retinotopic maps, embedded in a cortical sheet with well known, identifiable folding patterns. However, the relationship between these two ...
  • Frydman, Carola; Molly, Raven S. (Springer Science + Business Media B.V., 2011-02)
    The trends in executive pay and labor income tax rates since the 1940s suggest a high elasticity of taxable income with respect to tax policy. By contrast, the level and structure of executive compensation have been largely ...
  • Skow, Bradford (Philosophy of Science Association, 2011-07)
    Is there anything more to temperature than the ordering of things from colder to hotter? Are there also facts, for example, about how much hotter (twice as hot, three times as hot...) one thing is than another? There ...
  • Budish, Eric; Roin, Ben; Williams, Heidi L. (American Economic Association, 2015-07)
    We investigate whether private research investments are distorted away from long-term projects. Our theoretical model highlights two potential sources of this distortion: short-termism and the fixed patent term. Our empirical ...
  • Banerjee, Abhijit; Duflo, Esther (Oxford University Press, 2014-02)
    This article uses variation in access to a targeted lending program to estimate whether firms are credit constrained. While both constrained and unconstrained firms may be willing to absorb all the directed credit that ...
  • Armstrong, Christopher S.; Core, John E.; Guay, Wayne R. (Elsevier B.V., 2014-05)
    Although recent research documents a positive relation between corporate transparency and the proportion of independent directors, the direction of causality is unclear. We examine a regulatory shock that substantially ...
  • Crepon, Bruno; Duflo, Esther; Gurgand, Marc; Rathelot, Roland; Zamora, Philippe (Oxford University Press, 2013-01)
    This article reports the results from a randomized experiment designed to evaluate the direct and indirect (displacement) impacts of job placement assistance on the labor market outcomes of young, educated job seekers in ...
  • Lo, Andrew W.; Brennan, Thomas J. (University of Texas School of Law, 2012-01)
    A common theme in the regulation of financial institutions and transactions is leverage constraints. Although such constraints are implemented in various ways—from minimum net capital rules to margin requirements to credit ...
  • Gershman, Samuel J. (Springer US, 2015-01)
    Studies of reinforcement learning have shown that humans learn differently in response to positive and negative reward prediction errors, a phenomenon that can be captured computationally by positing asymmetric learning ...
  • Ho, Pin; Tu, Kun-Hua; Zhang, Jinshuo; Sun, Congli; Chen, Jingsheng; Liontos, George; Ntetsikas, Konstantinos; Avgeropoulos, Apostolos; Voyles, Paul M.; Ross, Caroline A. (2016-02)
    Perpendicular magnetic anisotropy [Co/Pd][subscript 15] and L1[subscript 0]-FePt nanowire arrays of period 63 nm with linewidths 38 nm and 27 nm and film thickness 27 nm and 20 nm respectively were fabricated using a ...
  • Liao, Qifeng; Willcox, Karen E. (Society for Industrial and Applied Mathematics, 2015-01)
    This paper proposes a decomposition approach for uncertainty analysis of systems governed by partial differential equations (PDEs). The system is split into local components using domain decomposition. Our domain-decomposed ...
  • Skirdkov, P. N.; Zvezdin, K. A.; Belanovsky, A. D.; Grollier, J.; Cros, V.; Ross, Caroline A.; Zvezdin, A. K. (American Institute of Physics, 2014-06)
    We demonstrate numerically the ability to displace a magnetic domain wall (DW) by remote spin current injection. We consider a long and narrow magnetic nanostripe with a single DW. The spin-polarized current is injected ...
  • Miao, Guoxing; Mascaro, Mark D.; Nam, C. H.; Ross, Caroline A.; Moodera, Jagadeesh (American Institute of Physics (AIP), 2011-07)
    In a nanowire consisting of a ferromagnet/insulator/superconductor multilayer structure, the superconductivity is shown to depend strongly on the configuration of the magnetic domain walls in the neighboring ferromagnetic ...
  • Navas, David Otero; Redondo, Carolina; Badini Confalonieri, Giovanni A.; Batallan, Francisco; Devishvili, Anton; Asenjo, Agustina; Ross, Caroline A.; Toperverg, Boris P.; Iglesias-Freire, Oscar (American Physical Society, 2014-08)
    Ferromagnetic domain patterns and three-dimensional domain-wall configurations in thin CoCrPt films with perpendicular magnetic anisotropy were studied in detail by combining magnetic force microscopy and polarized neutron ...
  • Narula, Rohit; Bonini, Nicola; Marzari, Nicola; Reich, Stephanie (American Physical Society, 2012-03)
    The dominant phonon wave vectors q* probed by the 2D Raman mode of pristine and uniaxially strained graphene are determined via a combination of ab initio calculations and a full two-dimensional integration of the transition ...
  • Jacks, Tyler E.; Xu, Jin; Haigis, Kevin M.; Firestone, Ari J.; McNerney, Megan E.; Li, Qing; Davis, Elizabeth; Chen, Shann-Ching; Nakitandwe, Joy; Downing, James; Le Beau, Michelle M.; Shannon, Kevin (American Association for Cancer Research, 2013-06)
    Biochemical properties of Ras oncoproteins and their transforming ability strongly support a dominant mechanism of action in tumorigenesis. However, genetic studies unexpectedly suggested that wild-type (WT) Ras exerts ...
  • Puig, M. Victoria; Rose, Jonas; Schmidt, Robert; Freund, Nadja (Frontiers Research Foundation, 2014-08)
    In this review, we provide a brief overview over the current knowledge about the role of dopamine transmission in the prefrontal cortex during learning and memory. We discuss work in humans, monkeys, rats, and birds in ...
  • Tye, Kay; Mirzabekov, Julie J.; Warden, Melissa R.; Ferenczi, Emily A.; Tsai, Hsing-Chen; Finkelstein, Joel; Kim, Sung-Yon; Adhikari, Avishek; Thompson, Kimberly R.; Andalman, Aaron S.; Gunaydin, Lisa A.; Witten, Ilana B.; Deisseroth, Karl (Nature Publishing Group, 2012-12)
    Major depression is characterized by diverse debilitating symptoms that include hopelessness and anhedonia1. Dopamine neurons involved in reward and motivation are among many neural populations that have been hypothesized ...
  • Gershman, Samuel J. (MIT Press, 2014-02)
    Temporal difference learning models of dopamine assert that phasic levels of dopamine encode a reward prediction error. However, this hypothesis has been challenged by recent observations of gradually ramping stratal ...
  • Maison, Stephane F.; Liu, Xiao-Ping; Eatock, Ruth Anne; Sibley, David R.; Grandy, David K.; Liberman, M. Charles (Society for Neuroscience, 2012-01)
    Pharmacological studies suggest that dopamine release from lateral olivocochlear efferent neurons suppresses spontaneous and sound-evoked activity in cochlear nerve fibers and helps control noise-induced excitotoxicity; ...
