  • Barros, E. B.; Sato, K.; Samsonidze, Ge. G.; Souza Filho, A. G.; Dresselhaus, Mildred; Saito, R. (American Physical Society, 2011-06)
    The D band Raman intensity is calculated for armchair edged graphene nanoribbons using an extended tight-binding method in which the effect of interactions up to the seventh nearest neighbor is taken into account. The ...
  • Khan, Omer; Lis, Mieszko; Sinangil, Yildiz; Devadas, Srinivas (Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
    Cache coherence lies at the core of functionally-correct operation of shared memory multicores. Traditional directory-based hardware coherence protocols scale to large core counts, but they incorporate complex logic and ...
  • Fricke, Tobin T; Abbott, Richard; Adhikari, Rana; Dooley, Katherine L; Frolov, Valery V; Kawabe, Keita; Slagmolen, Bram J J; Smith-Lefebvre, Nicolas D.; Evans, Matthew J.; Fritschel, Peter K.; Kissel, Jeffrey S.; Waldman, Sam J. (IOP Publishing, 2012-02)
    The two 4 km long gravitational wave detectors operated by the Laser Interferometer Gravitational-wave Observatory (LIGO) were modified in 2008 to read out the gravitational wave channel using the DC readout form of homodyne ...
  • Walfish, Michael; Vutukuru, Mythili; Balakrishnan, Hari; Karger, David R.; Shenker, Scott (Association for Computing Machinery, 2010-03)
    This article presents the design, implementation, analysis, and experimental evaluation of speak-up, a defense against application-level distributed denial-of-service (DDoS), in which attackers cripple a server by sending ...
  • Cho, Myong Hyon; Shim, Keun Sup; Khan, Omer; Devadas, Srinivas (Institute of Electrical and Electronics Engineers (IEEE), 2011-05)
    Several recent studies have proposed fine-grained, hardware-level thread migration in multicores as a solution to power, reliability, and memory coherence problems. The need for fast thread migration has been well documented, ...
  • Susskind, Lawrence E.; Field, Patrick (Association for Conflict Resolution, 2012-07)
    In 1996, we published the book Dealing with an Angry Public. In it we raised concerns about the distrustful attitudes that citizens have toward government and corporations, and the inability of these institutions to respond ...
  • Susskind, Lawrence E.; Field, Patrick (Association for Conflict Resolution, 2012-10)
    In the first part of this article published in the Summer 2012 issue of ACResolution Magazine, we noted that the principles we proposed in our 1996 book, Dealing with an Angry Public, have been adopted and used successfully ...
  • Wunsch, Carl (Journal of Marine Research/Yale, 2011-03)
    Elementary Sverdrup balance is tested in the context of the time-average of a 16-year duration time-varying ocean circulation estimate employing the great majority of global-scale data available between 1992 and 2007. The ...
  • Val Martin, M.; Ford, B.; Prenni, A. J.; Wiedinmyer, C.; Heald, Colette L. (Copernicus GmbH, 2013-08)
    We analyze the record of aerosol optical depth (AOD) measured by the MODerate resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite in combination with surface PM[subscript 2.5] to investigate the impact ...
  • Nurhati, Intan Suci; Cobb, Kim M.; Lorenzo, Emanuele Di (American Meteorological Society, 2011-06)
    Accurate projections of future temperature and precipitation patterns in many regions of the world depend on quantifying anthropogenic signatures in tropical Pacific climate against its rich background of natural variability. ...
  • Dewey, Daniel; Figueroa-Feliciano, Enectali; Bastien, Fabienne A.; Sato, Kosuke; Rutherford, John Morton; Heine, Sarah N.T.; Canizares, Claude R. (IOP Publishing, 2013-05)
    We present the analysis of 21 bright X-ray knots in the Cassiopeia A supernova remnant from observations spanning 10 yr. We performed a comprehensive set of measurements to reveal the kinematic and thermal state of the ...
  • Chakrabarty, Deepto; Morgan, Edward H.; Hartman, Jacob M.; Patruno, Alessandro; Markwardt, Craig B.; van der Klis, Michiel; Wijnands, Rudy (IOP Publishing, 2009-08)
    The Rossi X-ray Timing Explorer has observed five outbursts from the transient 2.5 ms accretion-powered pulsar SAX J1808.4–3658 during 1998-2008. We present a pulse timing study of the most recent outburst and compare it ...
  • Kaur, Gurneet; Ajoy, Ashok; Cappellaro, Paola (IOP Publishing, 2013-09)
    Strategies to protect multi-qubit states against decoherence are difficult to formulate because of their complex many-body dynamics. A better knowledge of the decay dynamics would help in the construction of dynamical ...
  • Schlapfer, Markus Stefan; Buzna, Lubos (American Physical Society, 2012-01)
    While degree correlations are known to play a crucial role for spreading phenomena in networks, their impact on the propagation speed has hardly been understood. Here we investigate a tunable spreading model on scale-free ...
  • Williams, Brian Charles; Ono, Masahiro (Institute of Electrical and Electronics Engineers, 2010-12)
    This paper considers finite-horizon optimal control for multi-agent systems subject to additive Gaussian-distributed stochastic disturbance and a chance constraint. The problem is particularly difficult when agents are ...
  • Jaillet, Patrick; Chen, Jie; Low, Kian Hsiang; Tan, Colin Keng-Yan; Dolan, John; Sukhatme, Gaurav; Oran, Ali (Association for Uncertainty in Artificial Intelligence (AUAI), 2012-08)
    The problem of modeling and predicting spatiotemporal traffic phenomena over an urban road network is important to many traffic applications such as detecting and forecasting congestion hotspots. This paper presents a ...
  • Tsitsiklis, John N.; Zoumpoulis, Spyridon Ilias; Kreidl, Olivier Patrick (Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
    We study a decentralized detection architecture in which each of a set of sensors transmits a highly compressed summary of its observations (a binary message) to a fusion center, which then decides on one of two alternative ...
  • Ahmed, Nisar; Luders, Brandon Douglas; Sample, Eric; Shah, Danelle; Campbell, Mark; How, Jonathan P.; Ponda, Sameera S. (American Institute of Aeromautics and Astronautics, 2011-08)
    This paper introduces a novel planning and estimation framework for maximizing infor- mation collection in missions involving cooperative teams of multiple autonomous vehicles and human agents, such as those used for ...
  • Ponda, Sameera S.; Redding, Josh; Choi, Han-Lim; How, Jonathan P.; Vavrina, Matt; Vian, John (Institute of Electrical and Electronics Engineers, 2010-07)
    This paper extends the consensus-based bundle algorithm (CBBA), a distributed task allocation framework previously developed by the authors, to address complex missions for a team of heterogeneous agents in a dynamic ...
  • Choi, Han-Lim; Whitten, Andrew Koo; How, Jonathan P. (Institute of Electrical and Electronics Engineers, 2010-07)
    This paper presents decentralized methods for allocating heterogeneous tasks to a network of agents with different capabilities, when the rules of engagement dictate various cooperation constraints. The new methods are ...
