  • Wallace, Gregory Marriner; Parker, Ronald R.; Bonoli, Paul T.; Hubbard, Amanda E.; Hughes, Jerry W.; LaBombard, Brian; Meneghini, Orso-Maria Corneli; Schmidt, Andrea Elizabeth; Shiraiwa, Shunichi; Whyte, Dennis G.; Wright, John C.; Wukitch, Stephen James; Smirnov, A. P.; Wilson, J. R. (American Institute of Physics, 2010-08)
    The goal of the Lower Hybrid Current Drive (LHCD) system on the Alcator C-Mod tokamak [ Hutchinson et al., Phys. Plasmas 1, 1511 (1994) ] is to investigate current profile control under plasma conditions relevant to future ...
  • Kuhn, Fabian; Lynch, Nancy Ann; Newport, Calvin Charles (Association for Computing Machinery, 2009-09)
    A diversity of possible communication assumptions complicates the study of algorithms and lower bounds for radio networks. We address this problem by defining an Abstract MAC Layer. This service provides reliable local ...
  • Burge, Christopher B.; Wang, Eric T.; Ramsköld, Daniel; Sandberg, Rickard (Public Library of Science, 2009-12)
    The parts of the genome transcribed by a cell or tissue reflect the biological processes and functions it carries out. We characterized the features of mammalian tissue transcriptomes at the gene level through analysis of ...
  • Ferrari, Raffaele; Lund, D. C.; Adkins, J. F. (American Geophysical Union (AGU), 2011-03)
    The ocean's role in regulating atmospheric carbon dioxide on glacial-interglacial timescales remains an unresolved issue in paleoclimatology. Reduced mixing between deep water masses may have aided oceanic storage of ...
  • Mohr, Justin T.; Speers, Anna E.; Wan, Chu; Spicer, Timothy P.; Fernandez-Vega, Virneliz; Chase, Peter; Hodder, Peter S.; Schürer, Stephan C.; Nomura, Daniel K.; Rosen, Hugh; Cravatt, Benjamin F.; Bachovchin, Daniel A.; Berlin, Jacob M.; Fu, Gregory C. (National Academy of Sciences, 2011-03)
    National Institutes of Health (NIH)-sponsored screening centers provide academic researchers with a special opportunity to pursue small-molecule probes for protein targets that are outside the current interest of, or beyond ...
  • Mascaro, Mark D.; Ross, Caroline A. (American Physical Society, 2010-12)
    he response of 360° [360 degrees]domain walls in narrow magnetic stripes to applied dc and ac currents, investigated by micromagnetic simulation, differs qualitatively from the response of 180° [180 degrees] domain walls. ...
  • Bilgic, Berkin; Setsompop, Kawin; Cohen-Adad, Julien; Wedeen, Van; Wald, Lawrence; Adalsteinsson, Elfar (Springer-Verlag Berlin Heidelberg, 2012)
    Diffusion Spectrum Imaging (DSI) offers detailed information on complex distributions of intravoxel fiber orientations at the expense of extremely long imaging times (~1 hour). It is possible to accelerate DSI by sub-Nyquist ...
  • Zargham, Michael; Ribeiro, Alejandro; Ozdaglar, Asuman E.; Jadbabaie, Ali (IEEE Control Systems Society, 2011-06)
    Dual descent methods are commonly used to solve network optimization problems because their implementation can be distributed through the network. However, their convergence rates are typically very slow. This paper ...
  • Bertsimas, Dimitris J.; Freund, Robert Michael; Sun, Xu Andy (Taylor & Francis, 2013-06)
    Our interest lies in solving sum of squares (SOS) relaxations of large-scale unconstrained polynomial optimization problems. Because interior-point methods for solving these problems are severely limited by the large-scale, ...
  • Huang, Enyang; Antoniou, Constantinos; Lopes, Jorge; Wen, Yang; Ben-Akiva, Moshe E. (Institute of Electrical and Electronics Engineers, 2010-09)
    Dynamic Traffic Assignment (DTA) system [Ben-Akiva et al., 1991] [Mahmassani, 2001] benefits travelers by providing accurate estimate of current traffic conditions, consistent anticipatory network information as well as ...
  • Patruno, Alessandro; Bult, Peter; Gopakumar, Achamveedu; Hartman, Jacob M.; Wijnands, Rudy; van der Klis, Michiel; Chakrabarty, Deepto (IOP Publishing, 2012-02)
    The accreting millisecond pulsar SAX J1808.4–3658 has shown a peculiar orbital evolution in the past with an orbital expansion much faster than expected from standard binary evolutionary scenarios. Previous limits on the ...
  • Weller, Daniel S.; Polimeni, Jonathan R.; Grady, Leo; Wald, Lawrence L.; Adalsteinsson, Elfar; Goyal, Vivek K. (Institute of Electrical and Electronics Engineers (IEEE), 2012-08)
    Accelerating magnetic resonance imaging (MRI) by reducing the number of acquired k-space scan lines benefits conventional MRI significantly by decreasing the time subjects remain in the magnet. In this paper, we formulate ...
  • Gertler, Frank; Veen, Ed van; Ma, Chi Him Eddie; Omura, Takao; Cobos, Enrique J.; Latrémolière, Alban; Ghasemlou, Nader; Brenner, Gary J.; Barrett, Lee; Sawada, Tomokazu; Gao, Fuying; Coppola, Giovanni; Costigan, Michael; Geschwind, Dan; Woolf, Clifford J. (American Society for Clinical Investigation, 2011-10)
    Although peripheral nerves can regenerate after injury, proximal nerve injury in humans results in minimal restoration of motor function. One possible explanation for this is that injury-induced axonal growth is too slow. ...
  • Maimone, Thomas J.; Noel, Timothy; Buchwald, Stephen Leffler (Wiley Blackwell, 2011-08)
    A flow process for Pd-catalyzed C-F bond formation is described. A microreactor with a packed-bed design allows for easy handling of large quantities of insoluble CsF with precise control over reaction times, efficient ...
  • Scott, Daniel; Lee, Joon; Silva, Ikaro; Park, Shinhyuk; Moody, George B.; Celi, Leo Anthony G.; Mark, Roger Greenwood (BioMed Central Ltd, 2013-01)
    Background: The Multiparameter Intelligent Monitoring in Intensive Care II (MIMIC-II) database is a free, public resource for intensive care research. The database was officially released in 2006, and has attracted a growing ...
  • Parandehgheibi, Ali; Medard, Muriel; Ozdaglar, Asuman E.; Shakkottai, Srinivas (Institute of Electrical and Electronics Engineers, 2010-12)
    We study the design of media streaming applications in the presence of multiple heterogeneous wireless access methods with different throughputs and costs. Our objective is to analytically characterize the trade-off between ...
  • Torralba, Antonio; Freeman, William T. (Springer-Verlag, 2014-03)
    We identify and study two types of “accidental” images that can be formed in scenes. The first is an accidental pinhole camera image. The second class of accidental images are “inverse” pinhole camera images, formed by ...
  • Torralba, Antonio; Freeman, William T. (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)
    We identify and study two types of “accidental” images that can be formed in scenes. The first is an accidental pinhole camera image. These images are often mistaken for shadows, but can reveal structures outside a room, ...
  • Abdulkadiroglu, Atila; Angrist, Joshua; Dynarski, Susan M.; Kane, Thomas J.; Pathak, Parag (President and Fellows of Harvard College, 2011-03)
    We use student assignment lotteries to estimate the effect of charter school attendance on student achievement in Boston. We also evaluate a related alternative, Boston's pilot schools. Pilot schools have some of the ...
