  • Thangavelautham, Jekanthan; El Samid, Nader Abu; Grouchy, Paul; Earon, Ernest; Fu, Terence; Nagrani, Nagina; D'Eleuterio, Gabriele M. T. (Institute of Electrical and Electronics Engineers, 2010-03)
    Autonomous robotic excavation has often been limited to a single robotic platform using a specified excavation vehicle. This paper presents a novel method for developing scalable controllers for use in multirobot scenarios ...
  • DeLong, Edward (Nature Publishing Group, 2009-05)
    Numerically, microbial species dominate the oceans, yet their population dynamics, metabolic complexity and synergistic interactions remain largely uncharted. A full understanding of life in the ocean requires more than ...
  • Demirtas, Sefa; Su, Guolong; Oppenheim, Alan V. (Institute of Electrical and Electronics Engineers (IEEE), 2013-05)
    Signal processing is a discipline in which functional composition and decomposition can potentially be utilized in a variety of creative ways. From an analysis point of view, further insight can be gained into existing ...
  • Tenenbaum, Joshua B.; Jonas, Eric M.; Roy, Daniel; Mansinghka, Vikash (Journal of Machine Learning Research, 2009-04)
    We introduce _adaptive sequential rejection sampling_, an algorithm for generating exact samples from high-dimensional, discrete distributions, building on ideas from classical AI search. Just as systematic search algorithms ...
  • Ba, Demba E.; Babadi, Behtash; Purdon, Patrick; Brown, Emery N. (Neural Information Processing Systems Foundation, Inc., 2012-12)
    We consider the problem of recovering a sequence of vectors, (Xk)[K over k=0], for which the increments X[subscript k] - X[subscript k-1] are S[subscript k]-sparse (with S[subscript k] typically smaller than S[subscript ...
  • Materassi, Donatello; Roychowdhury, Subhrajit; Hays, Thomas; Salapaka, Murti (BioMed Central Ltd, 2013-11)
    Background: Intracellular transport is crucial for many cellular processes where a large fraction of the cargo is transferred by motor-proteins over a network of microtubules. Malfunctions in the transport mechanism ...
  • Chindelevitch, Leonid; Trigg, Jason; Regev, Aviv; Berger, Bonnie (Nature Publishing Group, 2014-10)
    Constraint-based models are currently the only methodology that allows the study of metabolism at the whole-genome scale. Flux balance analysis is commonly used to analyse constraint-based models. Curiously, the results ...
  • Mueller, Timothy K.; Ceder, Gerbrand (American Physical Society, 2010-08)
    The cluster expansion has proven to be a valuable tool in materials science to predict properties of configurationally ordered and disordered structures but the generation of cluster expansions can be computationally ...
  • Freivogel, Benjamin W.; McGreevy, John; Suh, Sunok Josephine (American Physical Society, 2012-05)
    Any conformal field theory (CFT) on a sphere supports completely undamped collective oscillations. We discuss the implications of this fact for studies of thermalization using AdS/CFT. Analogous oscillations occur in ...
  • Adams, Allan; Lawrence, Albion; Swanson, Ian (American Physical Society, 2009-11)
    We construct exact two-dimensional conformal field theories, corresponding to closed string tachyon and metric profiles invariant under shifts in a null coordinate, which can be constructed from any two-dimensional ...
  • Jafferis, Daniel L.; Pufu, Silviu S. (Springer-Verlag/International School for Advanced Studies (SISSA), 2014-05)
    We apply the technique of supersymmetric localization to exactly compute the S [superscript 5] partition function of several large N superconformal field theories in five dimensions that have AdS6 duals in massive type IIA ...
  • Geng, You-Lin; Yuan, Ning; Qiu, Cheng-Wei (Institute of Electrical and Electronics Engineers, 2009-03)
    Electromagnetic fields in uniaxial anisotropic media can be obtained based on spherical vector wave functions in isotropic media. Applying the boundary conditions of electromagnetic fields on each interface of an impedance ...
  • Rha, ChoKyun; Brigham, Christopher J.; Sinskey, Anthony J.; Reimer, Esther N. (Springer, 2012-04)
    Polyhydroxyalkanoates (PHA) are biodegradable polymers that are attractive materials for use in tissue engineering and medical device manufacturing. Ralstonia eutropha is regarded as the model organism for PHA biosynthesis. ...
  • Yuan, Yixing; Whittle, Andrew (Springer-Verlag, 2013)
    This paper reviews the performance of two time-dependent constitutive models in predictions of one-dimensional consolidation. The Soft-Soil Creep model [1] is an example of an elastic-viscoplastic formulation that incorporates ...
  • Mekdeci, Brian; Ross, Adam Michael; Rhodes, Donna H.; Hastings, Daniel E. (International Council on Systems Engineering, 2011-06)
    Previous research has identified design principles that enable survivability for systems, but it is unclear if these principles are appropriate and sufficient for systems of systems as well. This paper presents a preliminary ...
  • Lee, Chia-Hua; Bose, Suman; Van Vliet, Krystyn J.; Karp, Jeffrey M.; Karnik, Rohit N. (American Chemical Society (ACS), 2010-12)
    The lateral displacement of cells orthogonal to a flow stream by rolling on asymmetrical receptor patterns presents a new opportunity for the label-free separation and analysis of cells. Understanding the nature of cell ...
  • Hohm, Olaf; Samtleben, Henning (American Physical Society, 2014-03)
    We present the details of the recently constructed E[subscript 6(6)]-covariant extension of 11-dimensional supergravity. This theory requires a 5 + 27-dimensional spacetime in which the “internal” coordinates transform in ...
  • Hohm, Olaf; Samtleben, Henning (American Physical Society, 2014-03)
    We introduce the exceptional field theory for the group E[subscript 7(7)], based on a (4+56)-dimensional spacetime subject to a covariant section condition. The “internal” generalized diffeomorphisms of the coordinates in ...
  • Hohm, Olaf; Samtleben, Henning (American Physical Society, 2014-09)
    We develop exceptional field theory for E[subscript 8(8)], defined on a (3 + 248)-dimensional generalized spacetime with extended coordinates in the adjoint representation of E[subscript 8(8)]. The fields transform under ...
  • Holton, Richard (Blackwell Publishers, 2009-12)
    Legal rules admit of exceptions; indeed, it has been a legal maxim that one can infer the existence of a rule from exceptions that are made to it. Hart claims that the exceptions do not admit of exhaustive statement (a ...
