  • Figalli, Alessio; Jerison, David (Elsevier, 2013-06)
    We investigate the regularity of the marginals onto hyperplanes for sets of finite perimeter. We prove, in particular, that if a set of finite perimeter has log-concave marginals onto a.e. hyperplane then the set is convex. ...
  • Slavov, Nikolai; van Oudenaarden, Alexander; van Oudenaarden, Alexander (Elsevier, 2012-06)
    Gene-expression responses to an input can depend on growth conditions; in this issue, Sasson et al. (2012) show that this dependence is lower when the input results in a high degree of promoter occupancy.
  • Goldwasser, Shafi; Kalai, Yael Tauman; Popa, Raluca Ada; Vaikuntanathan, Vinod; Zeldovich, Nickolai (Springer-Verlag Berlin Heidelberg, 2013)
    Cryptographic schemes for computing on encrypted data promise to be a fundamental building block of cryptography. The way one models such algorithms has a crucial effect on the efficiency and usefulness of the resulting ...
  • Bowers, Kevin D.; van Dijk, Marten; Juels, Ari; Oprea, Alina; Rivest, Ronald L. (Association for Computing Machinery, 2011-10)
    This paper presents a new challenge--verifying that a remote server is storing a file in a fault-tolerant manner, i.e., such that it can survive hard-drive failures. We describe an approach called the Remote Assessment of ...
  • Tegmark, Max Erik (American Physical Society, 2012-06)
    We analyze cosmology assuming unitary quantum mechanics, using a tripartite partition into system, observer, and environment degrees of freedom. This generalizes the second law of thermodynamics to ‘‘The system’s entropy ...
  • Paul, Rohan; Newman, Paul; Rus, Daniela L. (Institute of Electrical and Electronics Engineers (IEEE), 2012-05)
    Someday mobile robots will operate continually. Day after day, they will be in receipt of a never ending stream of images. In anticipation of this, this paper is about having a mobile robot generate apt and compact summaries ...
  • Bruneau, Emile Gabriel; Dufour, Nicholas Paul; Saxe, Rebecca R. (Public Library of Science, 2013-04)
    People are often called upon to witness, and to empathize with, the pain and suffering of others. In the current study, we directly compared neural responses to others' physical pain and emotional suffering by presenting ...
  • Liu, Adrian Chi-Yan; Tegmark, Max Erik (Wiley Blackwell, 2011-11)
    Before it becomes a sensitive probe of the epoch of reionization, the dark ages and fundamental physics, 21-cm tomography must successfully contend with the issue of foreground contamination. Broad-band foreground sources ...
  • Ritvo, Harriet (Rachel Carson Center for Environment and Society, 2014)
    There is no obvious line or boundary that separates wild animals from those that are not wild. Instead, there are expansive grey areas, of which the most conspicuous encompass the domesticated animals that have reverted ...
  • Szell, Michael; Thurner, Stefan (Nature Publishing Group, 2013-02)
    Superpositions of social networks, such as communication, friendship, or trade networks, are called multiplex networks, forming the structural backbone of human societies. Novel datasets now allow quantification and ...
  • Webb, Bryn D.; Shaaban, Sherin; Gaspar, Harald; Cunha, Luis F.; Schubert, Christian R.; Hao, Ke; Robson, Caroline D.; Chan, Wai-Man; Andrews, Caroline; MacKinnon, Sarah; Oystreck, Darren T.; Hunter, David G.; Iacovelli, Anthony J.; Ye, Xiaoqian; Camminady, Anne; Engle, Elizabeth C.; Jabs, Ethylin Wang; Schubert, Christian R. (Elsevier, 2012-07)
    Members of the highly conserved homeobox (HOX) gene family encode transcription factors that confer cellular and tissue identities along the antero-posterior axis of mice and humans. We have identified a founder homozygous ...
  • Patera, Anthony T.; Eftang, Jens L.; Ronquist, Einar M. (Society for Industrial and Applied Mathematics, 2010-10)
    We present a new “hp” parameter multi-domain certified reduced basis method for rapid and reliable online evaluation of functional outputs associated with parametrized elliptic partial differential equations. We propose, ...
  • Mendillo, Marc L.; Santagata, Sandro; Bell, George W.; Hu, Rong; Tamimi, Rulla M.; Fraenkel, Ernest; Ince, Tan A.; Whitesell, Luke; Lindquist, Susan; Koeva, Martina I. (Elsevier, 2012-08)
    Heat-Shock Factor 1 (HSF1), master regulator of the heat-shock response, facilitates malignant transformation, cancer cell survival, and proliferation in model systems. The common assumption is that these effects are ...
  • Jarosz, Daniel F.; Lindquist, Susan (American Association for the Advancement of Science (AAAS), 2010-12)
    How can species remain unaltered for long periods yet also undergo rapid diversification? By linking genetic variation to phenotypic variation via environmental stress, the Hsp90 protein-folding reservoir might promote ...
  • Whitesell, Luke; Santagata, Sandro; Mendillo, Marc L.; Lin, Nancy U.; Proia, David A.; Lindquist, Susan (National Academy of Sciences (U.S.), 2014-12)
    The efficacy of hormonal therapies for advanced estrogen receptor-positive breast cancers is limited by the nearly inevitable development of acquired resistance. Efforts to block the emergence of resistance have met with ...
  • Fang, Taotao; Danforth, Charles W.; Buote, David A.; Stocke, John T.; Shull, J. Michael; Gastaldello, Fabio; Canizares, Claude R. (IOP Publishing, 2014-10)
    Weak spectral features in BL Lacertae objects (BL Lacs) often provide a unique opportunity to probe the inner region of this rare type of active galactic nucleus. We present a Hubble Space Telescope/Cosmic Origins Spectrograph ...
  • Roediger, Joel; Veilleux, Sylvain; Ehlert, Steven; McDonald, Michael A. (IOP Publishing, 2014-08)
    We present far-UV spectroscopy from the Cosmic Origins Spectrograph on the Hubble Space Telescope of a cool, star-forming filament in the core of A1795. These data, which span 1025 Å < λrest < 1700 Å, allow for the ...
  • Schawinski, Kevin; Treister, Ezequiel; Urry, C. Megan; Cardamone, Carolin; Simmons, Brooke; Yi, Sukyoung K. (IOP Publishing, 2011-01)
    We present the rest-frame optical morphologies of active galactic nucleus (AGN) host galaxies at 1.5 < z < 3, using near-infrared imaging from the Hubble Space Telescope Wide Field Camera 3, the first such study of AGN ...
  • McDonald, Michael A.; Benson, Bradford A.; Veilleux, Sylvain; Bautz, Marshall W.; Reichardt, Christian L. (Institute of Physics/American Astronomical Society, 2013-03)
    We present Hubble Space Telescope Wide Field Camera 3 observations of the core of the Phoenix cluster (SPT-CLJ2344-4243) in five broadband filters spanning rest-frame 1000-5500 Å. These observations reveal complex, filamentary ...
  • Shah, Parikshit; Parrilo, Pablo A. (Institute of Electrical and Electronics Engineers (IEEE), 2010-12)
    We develop a complete state-space solution to ℋ[subscript 2]-optimal decentralized control of poset-causal systems with state-feedback. Our solution is based on the exploitation of a key separability property of the problem, ...
