  • Hill, Alison Lynn; Rand, David G.; Nowak, Martin A.; Christakis, Nicholas A. (Public Library of Science, 2010-11)
    Many behavioral phenomena have been found to spread interpersonally through social networks, in a manner similar to infectious diseases. An important difference between social contagion and traditional infectious diseases, ...
  • Fernandez-Val, I.; Chernozhukov, Victor V. (Oxford University Press, 2011-03)
    Quantile regression (QR) is an increasingly important empirical tool in economics and other sciences for analysing the impact a set of regressors has on the conditional distribution of an outcome. Extremal QR, or QR applied ...
  • Andrews, Donald W. K.; Barwick, Panle Jia (Econometric Society, 2012-11)
    This paper is concerned with tests and confi dence intervals for parameters that are not necessarily identifi ed and are de fined by moment inequalities. In the literature, different test statistics, critical value ...
  • Demory, Brice-Olivier; de Wit, Julien; Lewis, Nikole; Fortney, Jonathan; Zsom, Andras; Seager, Sara; Knutson, Heather; Heng, Kevin; Madhusudhan, Nikku; Gillon, Michael; Barclay, Thomas; Desert, Jean-Michel; Parmentier, Vivien; Cowan, Nicolas B. (IOP Publishing, 2013-10)
    We present new visible and infrared observations of the hot Jupiter Kepler-7b to determine its atmospheric properties. Our analysis allows us to (1) refine Kepler-7b's relatively large geometric albedo of Ag = 0.35 ± 0.02, ...
  • Nir, Oaz; Bakal, Chris; Perrimon, Norbert; Berger, Bonnie (Cold Spring Harbor Laboratory Press, 2010-02)
    Biological networks are highly complex systems, consisting largely of enzymes that act as molecular switches to activate/inhibit downstream targets via post-translational modification. Computational techniques have been ...
  • Loh, Po-Ru; Lipson, Mark; Berger, Bonnie; Patterson, Nick; Moorjani, Priya; Pickrell, Joseph K.; Reich, David (Genetics Society of America, The, 2013-02)
    Long-range migrations and the resulting admixtures between populations have been important forces shaping human genetic diversity. Most existing methods for detecting and reconstructing historical admixture events are based ...
  • Zucker, Jeremy; Brandes, Aaron; Lun, Desmond S.; Ip, Kuhn; Colijn, Caroline; Weiner, Brian; Galagan, James E. (Public Library of Science, 2012-05)
    Background: Bacteria have evolved the ability to efficiently and resourcefully adapt to changing environments. A key means by which they optimize their use of available nutrients is through adjustments in gene expression ...
  • Friedman, Jonathan; Alm, Eric J. (Public Library of Science, 2012-09)
    High-throughput sequencing based techniques, such as 16S rRNA gene profiling, have the potential to elucidate the complex inner workings of natural microbial communities - be they from the world's oceans or the human gut. ...
  • Eagle, Nathan N.; Lazer, David; Pentland, Alex Paul (United States National Academy of Sciences, 2009-08)
    Data collected from mobile phones have the potential to provide insight into the relational dynamics of individuals. This paper compares observational data from mobile phones with standard self-report survey data. We find ...
  • Jagabathula, Srikanth (Institute of Electrical and Electronics Engineers (IEEE), 2011-11)
    We consider the problem of recovering a function over the space of permutations (or, the symmetric group) over n elements from given partial information; the partial information we consider is related to the group theoretic ...
  • Kaufman, Joshua J.; Ottman, Richard; Tao, Guangming; Shabahang, Soroush; Banaei, Esmaeil-Hooman; Liang, Xiangdong; Johnson, Steven G.; Fink, Yoel; Chakrabarti, Ratna; Abouraddy, Ayman F. (National Academy of Sciences (U.S.), 2013-09)
    Polymeric micro- and nanoparticles are becoming a mainstay in biomedicine, medical diagnostics, and therapeutics, where they are used in implementing sensing mechanisms, as imaging contrast agents, and in drug delivery. ...
  • Doshi-Velez, Finale P.; Wingate, David; Tenenbaum, Joshua B.; Roy, Nicholas (International Machine Learning Society, 2011-06)
    We present the infinite dynamic Bayesian network model (iDBN), a nonparametric, factored state-space model that generalizes dynamic Bayesian networks (DBNs). The iDBN can infer every aspect of a DBN: the number of hidden ...
  • Kaneva, Biliana K.; Sivic, Josef; Torralba, Antonio; Avidan, Shai; Freeman, William T. (Institute of Electrical and Electronics Engineers (IEEE), 2010-05)
    We present a system for generating “infinite” images from large collections of photos by means of transformed image retrieval. Given a query image, we first transform it to simulate how it would look if the camera moved ...
  • Wingate, David; Goodman, Noah D.; Roy, Daniel; Tenenbaum, Joshua B. (Association for Uncertainty in Artificial Intelligence Press, 2009-06)
    We present the Infinite Latent Events Model, a nonparametric hierarchical Bayesian distribution over infinite dimensional Dynamic Bayesian Networks with binary state representations and noisy-OR-like transitions. The ...
  • Kaplan, C. Nadir; Hinczewski, Michael; Berker, A. Nihat (American Physical Society, 2009-01)
    For a variety of quenched random spin systems on an Apollonian network, including ferromagnetic and antiferromagnetic bond percolation and the Ising spin glass, we find the persistence of ordered phases up to infinite ...
  • Cirelli, Kimberly; Gorfu, Gezahegn; Hassan, Musa A.; Printz, Morton; Crown, Devorah; Leppla, Stephen H.; Grigg, Michael E.; Saeij, Jeroen; Moayeri, Mahtab (Public Library of Science, 2014-03)
    Toxoplasma gondii is an intracellular parasite that infects a wide range of warm-blooded species. Rats vary in their susceptibility to this parasite. The Toxo1 locus conferring Toxoplasma resistance in rats was previously ...
  • Patel, Suraj J.; Jindal, Rohit; King, Kevin R.; Tilles, Arno W.; Yarmush, Martin L. (Public Library of Science, 2011-05)
    Endothelial cells represent an important barrier between the intravascular compartment and extravascular tissues, and therefore serve as key sensors, communicators, and amplifiers of danger signals in innate immunity and ...
  • Oliehoek, Frans A.; Kaelbling, Leslie P.; Witwicki, Stefan J. (Association for the Advancement of Artifical Intelligence, 2012-07)
    This paper presents a theoretical advance by which factored POSGs can be decomposed into local models. We formalize the interface between such local models as the influence agents can exert on one another; and we prove ...
  • Dolecek, Lara; Shah, Devavrat (Institute of Electrical and Electronics Engineers, 2009-08)
    Motivated by the recent emergence of large online social networks, we seek to understand the effects the underlying social network (graph) structure and the information dynamics have on the creation of influence of an ...
  • Thompson, Tammy M.; Selin, Noelle Eckley (Copernicus GmbH, 2012-10)
    We use regional air quality modeling to evaluate the impact of model resolution on uncertainty associated with the human health benefits resulting from proposed air quality regulations. Using a regional photochemical model ...
