  • Huang, Shurui; Ramamoorthy, Aditya; Medard, Muriel (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    Consider a large file that needs to be multicast over a network to a given set of terminals. Storing the file at a single server may result in server overload. Accordingly, there are distributed storage solutions that ...
  • Medard, Muriel; Huang, Shurui; Ramamoorthy, Aditya (Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
    Content distribution over networks is often achieved by using mirror sites that hold copies of files or portions thereof to avoid congestion and delay issues arising from excessive demands to a single location. Accordingly, ...
  • Polyanskiy, Yury; Poor, H. Vincent; Verdu, Sergio (Institute of Electrical and Electronics Engineers, 2011-08)
    The minimum achievable energy per bit over memoryless Gaussian channels has been previously addressed in the limit when the number of information bits goes to infinity, in which case it is known that the availability of ...
  • Zafer, Murtaza; Modiano, Eytan H. (Institute of Electrical and Electronics Engineers / IEEE Control Systems Society, 2009-11)
    We consider optimal rate-control for energy-efficient transmission of data, over a time-varying channel, with packet-deadline constraints. Specifically, the problem scenario consists of a wireless transmitter with B units ...
  • Zhang, Xiangxiong; Shu, Chi-Wang (Springer-Verlag, 2011-12)
    The entropy solutions of the compressible Euler equations satisfy a minimum principle for the specific entropy (Tadmor in Appl Numer Math 2:211–219, 1986). First order schemes such as Godunov-type and Lax-Friedrichs schemes ...
  • Gutowski, Timothy G.; Liow, Yuh Han John; Sekulic, Dusan P. (Institute of Electrical and Electronics Engineers, 2010-07)
    The purpose of this paper is to address both the high values, and the large variation in reported values for the energy requirements for the production of carbon nanotubes. The paper includes an estimate of the standard ...
  • Garg, Jivtesh; Chen, Gang (American Physical Society, 2013-04)
    The thermal conductivity of silicon-germanium superlattices is computed from density-functional perturbation theory using relaxation times that include both anharmonic and interface roughness effects. A decrease in the ...
  • Tumova, Jana; Reyes Castro, Luis Ignacio; Karaman, Sertac; Frazzoli, Emilio; Rus, Daniela L. (Institute of Electrical and Electronics Engineers (IEEE), 2013-06)
    We consider the problem of automatic generation of control strategies for robotic vehicles given a set of high-level mission specifications, such as “Vehicle x must eventually visit a target region and then return to a ...
  • Grossman, Sharon Rachel; Shlyakhter, Ilya; Karlsson, Elinor K.; Tabrizi, Shervin; Andersen, Kristian; Rinn, John; Lander, Eric S.; Schaffner, Steve; Sabeti, Pardis C.; 1000 Genomes Project (BioMed Central Ltd., 2010-10)
    The human genome contains hundreds of regions in which the patterns of genetic variation indicate recent positive natural selection, yet for most of these the underlying gene and the advantageous mutation remain unknown. ...
  • Bressloff, Neil W; Kolachalama, Vijaya Bhasker; Nair, Prasanth B. (BioMed Central Ltd, 2007-12)
    Background: Arterial geometry variability is inevitable both within and across individuals. To ensure realistic prediction of cardiovascular flows, there is a need for efficient numerical methods that can systematically ...
  • Sinha, Subarna; Tsang, Emily K.; Zeng, Haoyang; Meister, Michela; Dill, David L. (Public Library of Science, 2014-07)
    Boolean implications (if-then rules) provide a conceptually simple, uniform and highly scalable way to find associations between pairs of random variables. In this paper, we propose to use Boolean implications to find ...
  • Hussain, Natasha K.; Hsin, Honor; Huganir, Richard L.; Sheng, Morgan Hwa-Tze (Society for Neuroscience, 2010-09)
    Misshapen/NIKs (Nck-interacting kinases)-related kinase (MINK) and closely related TRAF2/Nck-interacting kinase (TNIK) are proteins that specifically bind to activated Rap2 and are thus hypothesized to relay its downstream ...
  • Fjell, Anders M.; Westlye, Lars T.; Amlien, Inge; Espeseth, Thomas; Reinvang, Ivar; Raz, Naftali; Agartz, Ingrid; Dale, Anders M.; Walhovd, Kristine B.; Salat, David; Greve, Doug N.; Fischl, Bruce (Society for Neuroscience, 2009-07)
    Age is associated with substantial macrostructural brain changes. While some recent magnetic resonance imaging studies have reported larger age effects in men than women, others find no sex differences. As brain morphometry ...
  • Sun, Lei; Xie, Huangming; Mori, Marcelo A.; Alexander, Ryan; Yuan, Bingbing B.; Hattangadi, Shilpa M.; Liu, Qingqing; Kahn, C. Ronald; Lodish, Harvey F. (Nature Publishing Group, 2011-07)
    Mammals have two principal types of fat. White adipose tissue primarily serves to store extra energy as triglycerides, whereas brown adipose tissue is specialized to burn lipids for heat generation and energy expenditure ...
  • Juan, Aster H.; Kumar, Roshan M.; Marx, Joseph G.; Young, Richard A.; Sartorelli, Vittorio (Elsevier, 2009-10)
    Polycomb group (PcG) proteins exert essential functions in the most disparate biological processes. The contribution of PcG proteins to cell commitment and differentiation relates to their ability to repress transcription ...
  • Medeiros, Lea Ann; Dennis, Lucas M.; Gill, Mark E.; Houbaviy, Hristo; Markoulaki, Styliani; Fu, Dongdong; White, Amy C.; Kirak, Oktay; Sharp, Phillip A.; Page, David C.; Jaenisch, Rudolf (National Academy of Sciences (U.S.), 2011-08)
    Mir-290 through mir-295 (mir-290–295) is a mammalian-specific microRNA (miRNA) cluster that, in mice, is expressed specifically in early embryos and embryonic germ cells. Here, we show that mir-290–295 plays important roles ...
  • Ginzburg, Victor; Travkin, Roman; Finkelberg, Michael (Birkhäuser Basel, 2009-03)
    We compute the Frobenius trace functions of mirabolic character sheaves defined over a finite field. The answer is given in terms of the character values of general linear groups over the finite field, and the structure ...
  • Travkin, Roman (Birkhäuser Basel, 2009-04)
    The set of orbits of GL(V) in Fl(V) × Fl(V) × V is finite, and is parametrized by the set of certain decorated permutations in a work of Magyar, Weyman, and Zelevinsky. We describe a mirabolic RSK correspondence (bijective) ...
  • Artzi, Shay; Kiezun, Adam; Shomron, Noam (BioMed Central Ltd, 2008-01)
    Background MicroRNAs (miRNAs), present in most metazoans, are small non-coding RNAs that control gene expression by negatively regulating translation through binding to the 3'UTR of mRNA transcripts. Previously, experimental ...
  • Dilks, Daniel D.; Julian, Joshua B.; Kubilius, Jonas; Spelke, Elizabeth S.; Kanwisher, Nancy (Society for Neuroscience, 2011-06)
    Electrophysiological and behavioral studies in many species have demonstrated mirror-image confusion for objects, perhaps because many objects are vertically symmetric (e.g., a cup is the same cup when seen in left or right ...
