  • Trigg, Jason A.; Gutwin, Karl; Keating, Amy E.; Berger, Bonnie (Public Library of Science, 2011-08)
    The alpha-helical coiled coil can adopt a variety of topologies, among the most common of which are parallel and antiparallel dimers and trimers. We present Multicoil2, an algorithm that predicts both the location and ...
  • Paster, Eli Travis; Ruddy, Bryan P.; Pillai, Priam V.; Hunter, Ian (SPIE, 2011-03)
    Conducting polymer materials can be employed as actuation elements, length sensors, force sensors, energy storage devices, and electrical components. Combining the various functionalities of conducting polymers to create ...
  • Leonardi, Christopher Ross; Holmes, David W.; Williams, John R.; Tilke, Peter G. (Society for Modeling & Simulation International, 2011-04)
    This paper presents a numerical framework that enables scalable, parallel execution of engineering simulations on multi-core, shared memory architectures. Distribution of the simulations is done by selective hash-tabling ...
  • Finchelstein, D. F.; Sze, Vivienne; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2009-10)
    Performance requirements for video decoding will continue to rise in the future due to the adoption of higher resolutions and faster frame rates. Multicore processing is an effective way to handle the resulting increase ...
  • Bond, Robert A.; Kim, Hahn G. (Institute of Electrical and Electronics Engineers, 2009-10)
    Multicore architectures require parallel computation and explicit management of the memory hierarchy, both of which add programming complexity and are unfamiliar to most programmers. While MPI and OpenMP still have a place ...
  • Williams, John R.; Holmes, David W.; Tilke, Peter G. (Queen Mary, University of London, 2010-08)
    This paper discusses the implementation of particle based numerical methods on multi-core machines. In contrast to cluster computing, where memory is distributed across machines, multi-core machine can share memory across ...
  • Malakis, A.; Berker, A. Nihat; Hadjiagapiou, I.A.; Fytas, N.G.; Papakonstantinou, T. (American Physical Society, 2010-04)
    The effects of bond randomness on the phase diagram and critical behavior of the square lattice ferromagnetic Blume-Capel model are discussed. The system is studied in both the pure and disordered versions by the same ...
  • Kewlani, Gaurav; Iagnemma, Karl (Institute of Electrical and Electronics Engineers, 2009-12)
    The ability of mobile robots to quickly and accurately analyze their dynamics is critical to their safety and efficient operation. In field conditions, significant uncertainty is associated with terrain and/or vehicle ...
  • Doherty, Kathleen M; Nakka, Priyanka; King, Bracken M; Rhee, Soo-Yon; Holmes, Susan P; Shafer, Robert W; Radhakrishnan, Mala L (BioMed Central Ltd., 2011-12)
    Background Great strides have been made in the effective treatment of HIV-1 with the development of second-generation protease inhibitors (PIs) that are effective against historically multi-PI-resistant HIV-1 variants. ...
  • Feizi- Khankandi, Soheil; Medard, Muriel (Institute of Electrical and Electronics Engineers, 2010-03)
    In this paper, we consider the problem of multifunctional compression with side information. The problem is how we can compress a source X so that the receiver is able to compute some deterministic functions f[subscript ...
  • Englot, Brendan J.; Hover, Franz S. (Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
    A new algorithm for solving multi-goal planning problems in the presence of obstacles is introduced. We extend ant colony optimization (ACO) from its well-known application, the traveling salesman problem (TSP), to that ...
  • Kim, MinJi; Medard, Muriel; Barros, Joao (Institute of Electrical and Electronics Engineers (IEEE), 2010-09)
    In our previous work (`An Algebraic Watchdog for Wireless Network Coding'), we proposed a new scheme in which nodes can detect malicious behaviors probabilistically, police their downstream neighbors locally using overheard ...
  • Shin, Won-Yong; Lucani, Daniel Enrique; Medard, Muriel; Stojanovic, Milica; Tarokh, Vahid (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    Capacity scaling laws are analyzed in an underwater acoustic network with n regularly located nodes. A narrow-band model is assumed where the carrier frequency is allowed to scale as a function of n. In the network, we ...
  • Xiao, Rong; Chu, Kuang-Han; Wang, Evelyn N. (American Institute of Physics, 2009-05)
    A phenomenon is presented where a propagating liquid on an array of nanopillars with scalloped features can separate into multiple layers of liquid films. The scallops were found to act as energy barriers that favor liquid ...
  • Wei, Jun; Zheng, Haining; Chen, Haoliang; Ooi, Boon Hooi; Dao, M. H.; Cho, Wonjoon; Rizzoli, Paola M.; Tkalich, P.; Patrikalakis, Nicholas M. (International Society of Offshore and Polar Engineers, 2010-06)
    In June of 2009, a sea trial was carried out around Singapore to study and monitor physical, biological and chemical oceanographic parameters. Temperature, salinity and velocities were collected from multiple vehicles. ...
  • Fors, Brett P.; Buchwald, Stephen Leffler (American Chemical Society (ACS), 2010-10)
    An alternative approach to catalyst development, which led to a Pd catalyst based on two biarylphosphine ligands for C−N cross-coupling reactions, is reported. By effectively being able to take the form of multiple catalysts ...
  • Naseem, Tahira; Snyder, Benjamin; Eisenstein, Jacob; Barzilay, Regina (AI Access Foundation, 2009-11)
    We demonstrate the effectiveness of multilingual learning for unsupervised part-of-speech tagging. The central assumption of our work is that by combining cues from multiple languages, the structure of each becomes more ...
  • Sorin, Fabien; Fink, Yoel (SPIE, 2010-09)
    Recent discoveries have enabled the integration of metals, insulators and semiconductors structures into extended length of polymer fibers. This has heralded a novel path and platform towards sensing of different physical ...
  • Abouraddy, Ayman F.; Fink, Yoel (International Society for Optical Engineering, 2009-05)
    The process of optical imaging and the use of a glass lens have been hitherto inseparable since it is the lens that is responsible for mapping incoming rays to form an image. While performing this critical role, the lens, ...
  • Egusa, S.; Wang, Z.; Chocat, Noemie; Ruff, Z. M.; Stolyarov, Alexander Mark; Shemuly, D.; Sorin, F.; Rakich, P. T.; Joannopoulos, John D.; Fink, Yoel (Nature Publishing Group, 2010-07)
    Fibre materials span a broad range of applications ranging from simple textile yarns to complex modern fibre-optic communication systems. Throughout their history, a key premise has remained essentially unchanged: fibres ...
