  • Schwarzschild, Roger S. (Linguistic Society of America, 2013-05)
    I make two related proposals, one about directed scale segments and the other about the nature of degrees. Bale (2007, 2011) argued that degrees should be analyzed as sets of individuals and that degree arguments are created ...
  • Su, Meng (IOP Publishing, 2014-02)
    BICEP1 is a millimeter-wavelength telescope designed specifically to measure the inflationary B-mode polarization of the cosmic microwave background at degree angular scales. We present results from an analysis of the data ...
  • Sauer, Robert T.; Gur, Eyal (National Academy of Sciences (U.S.), 2009-10)
    AAA+ proteases are ATP-fueled machines that bind protein substrates via a degradation tag, unfold the molecule if necessary, and then translocate the polypeptide into a chamber for proteolysis. Tag recognition is normally ...
  • Mani, Ali; Bazant, Martin Z. (American Physical Society (APS), 2011-12)
    Salt transport in bulk electrolytes is limited by diffusion and advection, but in microstructures with charged surfaces (e.g., microfluidic devices, porous media, soils, or biological tissues) surface conduction and ...
  • Wang, Han; Hsu, Allen Long; Lee, Dong Seup; Kim, Ki Kang; Kong, Jing; Palacios, Tomas (Institute of Electrical and Electronics Engineers (IEEE), 2012-02)
    In this letter, we analyze the carrier transit delay in graphene field-effect transistors (GFETs).The extraction of the intrinsic delay provides a new way to directly estimate carrier velocity from the experimental data, ...
  • Modiano, Eytan H.; Le, Long Bao; Jagannathan, Krishna Prasanna (Institute of Electrical and Electronics Engineers, 2009-06)
    This paper studies delay properties of the well-known maximum weight scheduling algorithm in wireless ad hoc networks. We consider wireless networks with either one-hop or multihop flows. Specifically, this paper shows ...
  • Johnson, Stephen H.; Hashemi, Hila; Zhang, Baile; Joannopoulos, John D. (American Physical Society, 2010-06)
    We show that the difficulty of cloaking is fundamentally limited by delay-loss and delay-bandwidth limitations that worsen as the size of the object to be cloaked increases relative to the wavelength, using a simple model ...

  • Gamarnik, David; Tsitsiklis, John N; Zubeldia Suarez, Martin (Association for Computing Machinery (ACM), 2016-06)
    We consider the following distributed service model: jobs with unit mean, exponentially distributed, and independent processing times arrive as a Poisson process of rate λ N, with 0<λ<1, and are immediately dispatched to ...
  • Johnson, Daniel W.; Schmidt, Ulrich H.; Bittner, Edward A.; Christensen, Benjamin; Levi, Retsef; Pino, Richard M. (BioMed Central Ltd, 2013-07)
    Introduction: A paucity of literature exists regarding delays in transfer out of the intensive care unit. We sought to analyze the incidence, causes, and costs of delayed transfer from a surgical intensive care unit ...
  • de Oliveira Costa, Angelica; Ewall-Wice, Aaron Michael; Feng, Lu; Hewitt, Jacqueline N; Neben, Abraham Richard; Tegmark, Max Erik; Morgan, Eric R.; Williams, Christopher Leigh (IOP Publishing, 2016-12)
    The detection of redshifted 21 cm emission from the epoch of reionization (EoR) is a challenging task owing to strong foregrounds that dominate the signal. In this paper, we propose a general method, based on the delay ...
  • Markakis, Mihalis G.; Tsitsiklis, John N.; Modiano, Eytan H. (Institute of Electrical and Electronics Engineers (IEEE), 2014-02)
    We study scheduling and routing problems that arise in multi-hop wireline networks with a mix of heavy-tailed and light-tailed traffic. We analyze the delay performance of the widely studied class of Back-Pressure policies, ...
  • Kochman, Yuval; Wornell, Gregory W.; Yao, Huan (Institute of Electrical and Electronics Engineers (IEEE), 2011-01)
    We focus on the problem of real-time streaming over a blockage channel with long feedback delay, as arises in real-time satellite communication from a comm-on-the-move (COTM) terminal. For this problem, we introduce a ...
  • Naous, Jad; Stutsman, Ryan; Mazieres, David; McKeown, Nick; Zeldovich, Nickolai (Association for Computing Machinery, 2009-08)
    Network security is gravitating towards more centralized control. Strong centralization places a heavy burden on the administrator who has to manage complex security policies and be able to adapt to users' requests. To be ...
  • Chow, Clement Y.; Landers, John E.; Bergren, Sarah K.; Sapp, Peter C.; Grant, Adrienne E.; Jones, Julie M.; Everett, Lesley; Lenk, Guy M.; McKenna-Yasek, Diane M.; Weisman, Lois S.; Figlewicz, Denise; Brown, Robert H.; Meisler, Miriam H. (Elsevier B.V., 2009-01)
    Mutations of the lipid phosphatase FIG4 that regulates PI(3,5)P2 are responsible for the recessive peripheral-nerve disorder CMT4J. We now describe nonsynonymous variants of FIG4 in 2% (9/473) of patients with amyotrophic ...
  • Ajore, Ram; Raiser, David; McConkey, Marie; Jöud, Magnus; Boidol, Bernd; Mar, Brenton; Saksena, Gordon; Weinstock, David M; Armstrong, Scott; Ellis, Steven R; Ebert, Benjamin L; Nilsson, Bjorn (Wiley Blackwell, 2017-03)
    Heterozygous inactivating mutations in ribosomal protein genes (RPGs) are associated with hematopoietic and developmental abnormalities, activation of p53, and altered risk of cancer in humans and model organisms. Here we ...
  • Gao, Qing; Steine, Eveline J.; Barrasa, M. Inmaculada; Hockemeyer, Dirk; Pawlak, Mathias; Fu, Dongdong; Reddy, Seshamma; Bell, George W.; Jaenisch, Rudolf (National Academy of Sciences, 2011-10)
    Alterations in DNA methylation have been associated with genome-wide hypomethylation and regional de novo methylation in numerous cancers. De novo methylation is mediated by the de novo methyltransferases Dnmt3a and 3b, ...
  • Zapotecatl, Jorge L.; Rosenblueth, David A.; Gershenson Garcia, Carlos (Hindawi Publishing Corporation, 2017-05)
    Self-organizing traffic lights have shown considerable improvements compared to traditional methods in computer simulations. Self-organizing methods, however, use sophisticated sensors, increasing their cost and limiting ...
  • Entova-Aizenbud, Inna (Springer US, 2016-02)
    The Kronecker coefficients are the structural constants for the tensor categories of representations of the symmetric groups, namely, given three partitions λ,μ,τ of n, the multiplicity of λ in μ⊗τ is called the Kronecker ...
  • Sobolevsky, Stanislav; Szell, Michael; Campari, Riccardo; Smoreda, Zbigniew; Ratti, Carlo; Couronne, Thomas (Public Library of Science, 2013-12)
    Large-scale networks of human interaction, in particular country-wide telephone call networks, can be used to redraw geographical maps by applying algorithms of topological community detection. The geographic projections ...
