  • Zhou, Huihui; Desimone, Robert (Elsevier B.V., 2011-06)
    When we search for a target in a crowded visual scene, we often use the distinguishing features of the target, such as color or shape, to guide our attention and eye movements. To investigate the neural mechanisms of ...
  • L'Heureux, Zara E.; Kanwisher, Nancy; Golomb, Julie D. (Sage Publications/Association for Psychological Science, 2014-03)
    When people move their eyes, the eye-centered (retinotopic) locations of objects must be updated to maintain world-centered (spatiotopic) stability. Here, we demonstrated that the attentional-updating process temporarily ...
  • Glassman, Elena L.; Singh, Rishabh; Miller, Robert C. (Association for Computing Machinery (ACM), 2014-03)
    Open-ended homework problems such as coding assignments give students a broad range of freedom for the design of solutions. We aim to use the diversity in correct solutions to enhance student learning by automatically ...
  • Matthews, Lynn D.; Greenhill, Lincoln J.; Goddi, C.; Chandler, C. J.; Humphreys, E. M. L.; Kunz, M. W. (Institute of Physics/American Astronomical Society, 2010-01)
    We present multi-epoch Very Long Baseline Array imaging of the [superscript 28]SiO v = 1 and v = 2, J = 1-0 maser emission toward the massive young stellar object (YSO) Orion Source I. Both SiO transitions were observed ...
  • Allanore, Antoine (Electrochemical Society, 2014-11)
    The electrolytic decomposition of metal oxides to metal and oxygen is an extractive metallurgy principle that, when coupled with carbon-free electricity, drastically mitigates the global warming impact of metal production. ...
  • Poggio, Tomaso A.; Weston, Jason; Mukherjee, Sayan; Pontil, Massimiliano; Chapelle, Olivier; Vapnik, Vladimir (Neural Information Processing Systems Foundation, 2000)
    We introduce a method of feature selection for Support Vector Machines. The method is based upon finding those features which minimize bounds on the leave-one-out error. This search can be efficiently performed via gradient ...
  • Youngster, I.; Sauk, J.; Pindar, C.; Wilson, R. G.; Kaplan, J. L.; Russell, G. H.; Hohmann, E. L.; Smith, Mark Burnham; Alm, Eric J; Gevers, Dirk (Oxford University Press, 2014-04)
    Fecal microbiota transplant is increasingly used to treat recurrent or relapsing Clostridium difficile infection. In this randomized controlled study, using a frozen inoculum from unrelated donors was safe and effective, ...
  • Grogan, Paul Thomas; de Weck, Olivier L. (American Society of Civil Engineers, 2012-04)
    Future human space exploration will require large amounts of resources for shielding and building materials, propellants, and consumables. A space-based resource economy could produce, transport, and store resource at ...
  • Medard, Muriel; Sundararajan, Jay-Kumar; Sadeghi, Parastoo (Institute of Electrical and Electronics Engineers, 2009-06)
    We propose a new feedback-based adaptive coding scheme for a packet erasure broadcast channel. The main performance metric of interest is the delay. We consider two types of delay - decoding delay and delivery delay. ...
  • Sanchez, Alvaro; Gore, Jeff (Public Library of Science, 2013-04)
    The evolutionary spread of cheater strategies can destabilize populations engaging in social cooperative behaviors, thus demonstrating that evolutionary changes can have profound implications for population dynamics. At ...
  • Shrader, Brooke E.; Permuter, Haim (Institute of Electrical and Electronics Engineers, 2009-07)
    In this work, we find the capacity of a compound finite-state channel (FSC) with time-invariant deterministic feedback. We consider the use of fixed length block codes over the compound channel. Our achievability result ...
  • Roberts, John William; Manchester, Ian R.; Tedrake, Russell Louis (Institute of Electrical and Electronics Engineers, 2011-04)
    Reinforcement Learning offers a very general framework for learning controllers, but its effectiveness is closely tied to the controller parameterization used. Especially when learning feedback controllers for weakly stable ...
  • Ny, Jerome Le; Balakrishnan, Hamsa (American Institute of Aeronautics and Astronautics, 2011-05)
    This paper proposes a general modeling framework adapted to the feedback control of traffic flows in Eulerian models of the National Airspace System. It is shown that the problems of scheduling and routing aircraft flows ...
  • Mahadevan, L.; Ocko, Samuel Alan (American Physical Society, 2015-04)
    An active conducting medium is one where the resistance (conductance) of the medium is modified by the current (flow) and in turn modifies the flow, so that the classical linear laws relating current and resistance, e.g., ...
  • Polyanskiy, Yury; Poor, H. Vincent; Verdu, Sergio (Institute of Electrical and Electronics Engineers, 2011-08)
    Without feedback, the backoff from capacity due to non-asymptotic blocklength can be quite substantial for blocklengths and error probabilities of interest in many practical applications. In this paper, novel achievability ...
  • Liu, Ying; Chandrasekaran, Venkat; Anandkumar, Animashree; Willsky, Alan S. (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    For Gaussian graphical models with cycles, loopy belief propagation often performs reasonably well, but its convergence is not guaranteed and the computation of variances is generally incorrect. In this paper, we identify ...
  • Mozdzanowska, Aleksandra L.; Weibel, R. E.; Hansman, Robert J., Jr. (Institute of Electrical and Electronics Engineers, 2009-01)
    The U.S. air transportation system faces substantial challenges in implementing new aviation information systems to meet future demand. These challenges need to be understood and addressed in order to successfully meet ...
  • Altafini, C.; Cappellaro, Paola; Cory, David G. (Institute of Electrical and Electronics Engineers, 2010-01)
    In NMR spectroscopy, the collective measurement is weakly invasive and its back-action is called radiation damping. The aim of this paper is to provide a control-theoretical analysis of the problem of suppressing this ...
  • Beaman, Lori; Duflo, Esther; Pande, Rohini; Topalova, Petia (American Association for the Advancement of Science (AAAS), 2012-01)
    Exploiting a randomized natural experiment in India, we show that female leadership influences adolescent girls’ career aspirations and educational attainment. A 1993 law reserved leadership positions for women in randomly ...
  • Sadler, Bess; Bourg, Chris (Code4Lib Journal, 2015-04)
    This paper discusses the various ways in which the practices of libraries and librarians influence the diversity (or lack thereof) of scholarship and information access. We examine some of the cultural biases inherent in ...
