  • King, A. L.; Miller, J. M.; Cackett, E. M.; Fabian, A. C.; Markoff, S.; Rupen, M.; Reynolds, M. T.; Nowak, Michael A.; Gultekin, K. (IOP Publishing, 2010-02)
    We report on the results of a simultaneous monitoring campaign employing eight Chandra X-ray (0.5-10 keV) and six Very Large Array/Extended Very Large Array (8.4 GHz) radio observations of NGC 4051 over seven months. ...
  • Shabalina, Svetlana A.; Ogurtsov, Aleksey Y.; Spiridonov, Alexey Nikolaevich; Novichkov, Pavel S.; Spiridonov, Nikolay A.; Koonin, Eugene V. (Oxford University Press on behalf of the Society for Molecular Biology and Evolution, 2010-04)
    Comparison of expression levels and breadth and evolutionary rates of intronless and intron-containing mammalian genes shows that intronless genes are expressed at lower levels, tend to be tissue specific, and evolve ...
  • Dragoi, George; Tonegawa, Susumu (National Academy of Sciences (U.S.), 2013-05)
    The activity of ensembles of hippocampal place cells represents a hallmark of an animal’s spatial experience. The neuronal mechanisms that enable the rapid expression of novel place cell sequences are not entirely understood. ...
  • Vieux (Kloss), Ellen; Wohlever, Matthew Lee; Chen, James Z.; Sauer, Robert T.; Baker, Tania (National Academy of Sciences (U.S.), 2013-05)
    Lon is an ATPase associated with cellular activities (AAA+) protease that controls cell division in response to stress and also degrades misfolded and damaged proteins. Subunits of Lon are known to assemble into ring-shaped ...
  • Triantafyllou, Christina; Brown, Emery N.; Whitfield-Gabrieli, Susan; Scholz, Jonathan; Saxe, Rebecca R. (Public Library of Science, 2009-03)
    In functional magnetic resonance imaging (fMRI) studies, a cortical region in the right temporo-parietal junction (RTPJ) is recruited when participants read stories about people's thoughts (‘Theory of Mind’). Both fMRI and ...
  • Kim, Seokhee; Sauer, Robert T. (Cold Spring Harbor Laboratory Press, 2014-04)
    Intracellular proteases combat proteotoxic stress by degrading damaged proteins, but their activity must be carefully controlled to maintain cellular fitness. The activity of Escherichia coli DegP, a highly conserved ...
  • McLaughlin, Nathan; Foster, Kelly A.; Edbauer, Dieter; Phillips, Marnie A.; Bolton, Andrew Donald; Constantine-Paton, Martha; Sheng, Morgan Hwa-Tze (Society for Neuroscience, 2010-02)
    NMDA receptors (NMDARs) are critical mediators of activity-dependent synaptic plasticity, but the differential roles of NR2A- versus NR2B-containing NMDARs have been controversial. Here, we investigate the roles of NR2A ...
  • Haslanger, Sally (Muse - Johns Hopkins University Press, 2015-03)
    Recent work on social injustice has focused on implicit bias as an important factor in explaining persistent injustice in spite of achievements on civil rights. In this paper, I argue that because of its individualism, ...
  • Gordan, Raluca; Hartemink, Alexander J.; Bulyk, Martha L. (Cold Spring Harbor Laboratory Press, 2009-08)
    Transcriptional regulation is largely enacted by transcription factors (TFs) binding DNA. Large numbers of TF binding motifs have been revealed by ChIP-chip experiments followed by computational DNA motif discovery. However, ...
  • Aral, Sinan; Sundararajan, Arun; Muchnik, Lev (National Academy of Sciences, 2009-12)
    Node characteristics and behaviors are often correlated with the structure of social networks over time. While evidence of this type of assortative mixing and temporal clustering of behaviors among linked nodes is used to ...
  • Gallagher, Gillian; Coon Burgess, Jessica Louise (Springer Science + Business Media B.V., 2009-08)
    This paper argues that long-distance assimilations between consonants come in two varieties: Total identity, which arises via a non-local relation between the interacting segments; and partial identity, which results from ...
  • Gilpin, Kyle W.; Rus, Daniela L. (Institute of Electrical and Electronics Engineers (IEEE), 2012-05)
    We present our digital fabrication technique for manufacturing active objects in 2D from a collection of smart particles. Given a passive model of the object to be formed, we envision submerging this original in a vat of ...
  • Pavone, Marco; Arsie, Alessandro; Frazzoli, Emilio; Bullo, Francesco (Institute of Electrical and Electronics Engineers (IEEE), 2011-08)
    A widely applied strategy for workload sharing is to equalize the workload assigned to each resource. In mobile multiagent systems, this principle directly leads to equitable partitioning policies whereby: 1) the environment ...
  • Wei, Ermin; Ozdaglar, Asuman E. (Institute of Electrical and Electronics Engineers (IEEE), 2012-12)
    We consider a network of agents that are cooperatively solving a global unconstrained optimization problem, where the objective function is the sum of privately known local objective functions of the agents. Recent literature ...
  • Tsitsiklis, John N.; Hendrickx, Julien; Olshevsky, Alexander (Institute of Electrical and Electronics Engineers (IEEE), 2011-08)
    We propose a model for deterministic distributed function computation by a network of identical and anonymous nodes. In this model, each node has bounded computation and storage capabilities that do not grow with the network ...
  • Hendrickx, Julien; Olshevsky, Alexander; Tsitsiklis, John N. (Institute of Electrical and Electronics Engineers, 2010-01)
    We propose a model for deterministic distributed function computation by a network of identical and anonymous nodes, with bounded computation and storage capabilities that do not scale with the network size. Our goal is ...
  • Bertsekas, Dimitri P.; Yu, Huizhen (University of Illinois at Urbana-Champaign, 2010-09)
    We consider the distributed solution of dynamic programming (DP) problems by policy iteration. We envision a network of processors, each updating asynchronously a local policy and a local cost function, defined on a ...
  • Jung, Kyomin; Shah, Devavrat; Shin, Jinwoo (Institute of Electrical and Electronics Engineers (IEEE), 2009-12)
    Motivated by applications of distributed linear estimation, distributed control, and distributed optimization, we consider the question of designing linear iterative algorithms for computing the average of numbers in a ...
  • Correll, Nikolaus; Martinoli, Alcherio; Amstutz, Patrick (Springer Netherlands, 2009-03)
    We study distributed boundary coverage of known environments using a team of miniature robots. Distributed boundary coverage is an instance of the multi-robot task-allocation problem and has applications in inspection, ...
  • McLurkin, James; Demaine, Erik D. (Institute of Electrical and Electronics Engineers, 2009-12)
    We describe a distributed boundary detection algorithm suitable for use on multi-robot systems with dynamic network topologies. We assume that each robot has access to its local network geometry, which is the combination ...
