  • Jukic, Dario; Buljan, Hrvoje; Lee, Dung-Hai; Joannopoulos, John D.; Soljacic, Marin (Optical Society of America, 2012-12)
    We point out that 2D photonic crystals (PhCs) can support surface bands that are pinned to Dirac points. These bands can be made very flat by optimizing the parameters of the system. Surface modes are found at the interface ...
  • Demaine, Erik D.; Eisenstat, Sarah Charmian (Springer Berlin / Heidelberg, 2011-08)
    Planar configurations of fixed-angle chains and trees are well studied in polymer science and molecular biology. We prove that it is strongly NP-hard to decide whether a polygonal chain with fixed edge lengths and angles ...
  • Amin, Mustafa Abdulkader; Shirokoff, David George (American Physical Society, 2010-04)
    Oscillons are extremely long lived, oscillatory, spatially localized field configurations that arise from generic initial conditions in a large number of nonlinear field theories. With an eye towards their cosmological ...
  • Drennan, Catherine L.; Hamill, Michael J.; Jost, Marco; Wong, Cintyu; Elliott, Sean J. (American Chemical Society (ACS), 2011-10)
    The process known as “adaptive response” allows Escherichia coli to respond to small doses of DNA-methylating agents by upregulating the expression of four proteins. While the role of three of these proteins in mitigating ...
  • Craig, Nathaniel; McCullough, Matthew Philip; Thaler, Jesse (Springer-Verlag, 2012-06)
    If supersymmetry (SUSY) solves the hierarchy problem, then naturalness considerations coupled with recent LHC bounds require non-trivial superpartner flavor structures. Such “Natural SUSY” models exhibit a large mass ...
  • Taylor, Frank E. (American Physical Society, 2014-09)
    A measurement of the B[0 over s] → J/ψϕ decay parameters, updated to include flavor tagging is reported using 4.9  fb[superscript −1] of integrated luminosity collected by the ATLAS detector from √s = 7  TeV pp collisions ...
  • Voigts, Jakob; Pritchett, Dominique L.; Moore, Christopher I.; Siegle, Joshua Handman (Frontiers Research Foundation, 2013-05)
    Electrophysiological recordings from ensembles of neurons in behaving mice are a central tool in the study of neural circuits. Despite the widespread use of chronic electrophysiology, the precise positioning of recording ...
  • de Weck, Olivier L.; Armar, Nii; Grogan, Paul Thomas; Siddiqi, Afreen; Lee, Gene; Jordan, Elizabeth; Shishko, Robert (American Institute of Aeronautics and Astronautics, 2009-09)
    This paper summarizes the motivation for and the resulting development of a flexible object-oriented software model for simulation and analysis of space exploration campaign logistics. The software model was designed to ...
  • Piore, Michael J. (Oxford University Press, 2011-01)
    This paper compares and contrasts the U.S. and French systems of labor market regulation. The U.S. system is specialized: Regulating authority is dispersed among a host of different agencies each with a relatively narrow ...
  • Blackford, J.; Hardman-Mountford, N. J.; Polimene, L.; Geider, R. J.; Talmy, David; Follows, Michael J. (Copernicus GmbH, 2014-09)
    Phytoplankton cell size influences particle sinking rate, food web interactions and biogeographical distributions. We present a model in which the uptake, storage and assimilation of nitrogen and carbon are explicitly ...
  • Williams, Brian Charles; Conrad, Patrick Raymond; Shah, Julie A. (Association for the Advancement of Artificial Intelligence, 2009-09)
    Dynamic plan execution strategies allow an autonomous agent to respond to uncertainties while improving robustness and reducing the need for an overly conservative plan. Executives have improved this robustness by ...
  • Fernandes, M. S.; Lee, K. S.; Ram, Rajeev J.; Correia, J. H.; Mendes, P. M. (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
    We present a new type of flexible dry copper electrodes based on Polydimethylsiloxane (PDMS) coatings, requiring no electrical contact with the body. Tests were performed in order to evaluate the performance of these types ...
  • Yip, Marcus; He, David Da; Winokur, Eric S.; Balderrama, Amanda Gaudreau; Sheridan, Robert; Ma, Hongshen (Institute of Electrical and Electronics Engineers, 2009-11)
    Pressure ulcers are painful sores that arise from prolonged exposure to high pressure points, which restricts blood flow and leads to tissue necrosis. This is a common occurrence among patients with impaired mobility, ...
  • Viana, J.C.; Pontes, A.J.; Rocha, L.A.; Guzman De Villoria, R.; Wardle, Brian L.; Sepulveda, A.T. (Elsevier, 2012-11)
    Flexible capacitive pressure sensors fabricated with nanocomposites were experimentally characterized and results compared with simulations from analytical modeling. Unlike traditional diaphragm silicon pressure sensors, ...
  • Tsang, Wei Mong; Stone, Alice L.; Aldworth, Zane N.; Hildebrand, John G.; Daniel, Tom L.; Akinwande, Akintunde Ibitayo; Voldman, Joel (Institute of Electrical and Electronics Engineers, 2010-07)
    We describe a flexible multisite microelectrode for insect flight biasing using neural stimulation. The electrode is made of two layers of polyimide (PI) with gold sandwiched in between in a split-ring geometry. The ...

  • Stribling, Jeremy; Sovran, Yair; Zhang, Irene; Pretzer, Xavid F.; Li, Jinyang; Kaashoek, M. Frans; Morris, Robert Tappan (USENIX Association, 2009-04)
    WheelFS is a wide-area distributed storage system intended to help multi-site applications share data and gain fault tolerance. WheelFS takes the form of a distributed file system with a familiar POSIX interface. Its design ...
  • Jordt, Andreas; Maes, Pattie; Steimle, Jurgen (Association for Computing Machinery (ACM), 2013-04)
    Flexpad is an interactive system that combines a depth camera and a projector to transform sheets of plain paper or foam into flexible, highly deformable, and spatially aware handheld displays. We present a novel approach ...

(Society of Photo-Optical Instrumentation Engineers, 2008-07)
    The X-ray Imaging Spectrometer (XIS) on board the Suzaku satellite is an X-ray CCD camera system that has features of a low background, high quantum efficiency, and good energy resolution in the 0.2 - 12 keV band. Because ...
  • Chen, Hongsheng; Chen, Min (Elsevier B.V., 2011-01)
    Charged particles moving faster than light in a medium produce Cherenkov radiation. In traditional, positive index-of-refraction materials this radiation travels forward. Metamaterials, with negative indices of refraction, ...
