  • Huynh, D. B. P.; Knezevic, David; Chen, Y.; Hesthaven, J. S.; Patera, Anthony T. (Elsevier ScienceDirect, 2010-06)
    We present a new approach for the construction of lower bounds for the inf-sup stability constants required in a posteriori error analysis of reduced basis approximations to affinely parametrized partial differential ...
  • Lawler, Gregory F.; Sheffield, Scott; Sheffield, Scott Roger (Institute of Mathematical Statistics, 2011-09)
    The Schramm–Loewner evolution (SLE[subscript κ]) is a candidate for the scaling limit of random curves arising in two-dimensional critical phenomena. When κ < 8, an instance of SLE[subscript κ] is a random planar curve ...
  • Chang, Howard C.; Paek, Jennifer; Kim, Dennis H. (Nature Publishing Group, 2011-12)
    Heritable variation in behavioural traits generally has a complex genetic basis1, and thus naturally occurring polymorphisms that influence behaviour have been defined in only rare instances2,3. The isolation of wild ...
  • Giesa, Tristan; Pugno, Nicola M.; Buehler, Markus J. (American Physical Society, 2012-10)
    Many fibers in biomaterials such as tendon, elastin, or silk feature a nonlinear stiffening behavior of the stress-strain relationship, where the rigidity of the material increases severely as the material is being stretched. ...
  • Helmreich, Stefan (John Wiley & Sons, Inc., 2011-03)
    This essay considers seawater as a substance and symbol in anthropological and social theory. Seawater has occupied an ambiguous place with respect to anthropological categories of nature and culture. Seawater as nature ...
  • Berwick, Robert C.; Hauser, Marc D.; Tattersall, Ian (Frontiers Research Foundation, 2013-09)
    Dediu and Levinson (2013) link two extraordinary claims: first, humans and Neanderthals were one and the same species and second, “Speech and language … are ancient, being present in a modern-like form over half a million ...
  • Sistiaga, Ainara; Mallol, Carolina; Galvan, Bertila; Summons, Roger Everett (Public Library of Science, 2014-06)
    Neanderthal dietary reconstructions have, to date, been based on indirect evidence and may underestimate the significance of plants as a food source. While zooarchaeological and stable isotope data have conveyed an image ...
  • Madsen, Ole S.; Negara, Arlendenovega Satria; Lim, Kian Yew; Cheong, Hin Fatt (Coastal Engineering Research Council, 2010-07)
    Experimental results for near-bottom current velocity profiles for flows over artificial, definitely 2D ripples made of 1.5 cm high aluminum angle -profile spaced at 10 cm intervals are obtained for the following cases: ...
  • Ilic, Ognjen; Jablan, Marinko; Joannopoulos, John D.; Celanovic, Ivan; Buljan, Hrvoje; Soljacic, Marin (American Physical Society, 2012-04)
    It is shown that thermally excited plasmon-polariton modes can strongly mediate, enhance, and tune the near-field radiation transfer between two closely separated graphene sheets. The dependence of near-field heat exchange ...
  • Timko, Brian P.; Arruebo, Manuel; Shankarappa, Sahadev A.; McAlvin, J. Brian; Okonkwo, Obiajulu Stephanie; Mizrahi, Boaz; Stefanescu, Cristina F.; Gomez, Leyre; Zhu, Jia; Zhu, Angela; Santamaria, Jesus; Langer, Robert; Kohane, Daniel S. (National Academy of Sciences (U.S.), 2014-01)
    A reservoir that could be remotely triggered to release a drug would enable the patient or physician to achieve on-demand, reproducible, repeated, and tunable dosing. Such a device would allow precise adjustment of dosage ...
  • Osedach, Timothy P.; Iacchetti, Antonio; Lunt, Richard R.; Andrew, Trisha L.; Brown, Patrick Richard; Akselrod, Gleb Markovitch; Bulovic, Vladimir (American Institute of Physics (AIP), 2012-09)
    We demonstrate a near-infrared photodetector that consists of a thin film of the J-aggregating cyanine dye, U3, and transparent metal-oxide charge transport layers. The high absorption coefficient of the U3 film, combined ...
  • Carter, Joshua Adam; Winn, Joshua Nathan; Gilliland, Ronald; Holman, Matthew J. (American Astronomical Society, 2009-04)
    The transiting exoplanet HD 149026b is an important case for theories of planet formation and planetary structure, for the planet's relatively small size has been interpreted as evidence for a highly metal-enriched ...
  • Bando, Yosuke; Raskar, Ramesh; Holtzman, Henry N. (Association for Computing Machinery (ACM), 2013-04)
    Recently, several camera designs have been proposed for either making defocus blur invariant to scene depth or making motion blur invariant to object motion. The benefit of such invariant capture is that no depth or motion ...
  • Panigrahi, Debmalya; Karger, David R. (Society for Industrial and Applied Mathematics, 2009-01)
    We present an Õ(m) (near-linear) time Monte Carlo algorithm for constructing the cactus data structure, a useful representation of all the global minimum edge cuts of an undirected graph. Our algorithm represents a fundamental ...
  • Wang, Fa; Ran, Ying (American Physical Society (APS), 2011-12)
    Motivated by recent experiments on the material Ba[subscript 3]NiSb[subscript 2]O[subscript 9], we consider a spin-one quantum antiferromagnet on a triangular lattice with the Heisenberg bilinear and biquadratic exchange ...
  • Bernstein, Aaron; Karger, David R. (Association for Computing Machinery, 2009)
    We present an improved oracle for the distance sensitivity problem. The goal is to preprocess a directed graph G = (V,E) with non-negative edge weights to answer queries of the form: what is the length of the shortest path ...
  • Hassanieh, Haitham; Indyk, Piotr; Katabi, Dina; Price, Eric C. (Association for Computing Machinery (ACM), 2012-05)
    We consider the problem of computing the k-sparse approximation to the discrete Fourier transform of an n-dimensional signal. We show: An O(k log n)-time randomized algorithm for the case where the input signal has at most ...
  • Daskalakis, Constantinos; Deckelbaum, Alan T.; Kim, Anthony (Society for Industrial and Applied Mathematics, 2011-01)
    We propose a new no-regret learning algorithm. When used against an adversary, our algorithm achieves average regret that scales as O (1/√T) with the number T of rounds. This regret bound is optimal but not rare, as there ...
  • Candogan, Utku Ozan; Menache, Ishai; Ozdaglar, Asuman E.; Parrilo, Pablo A. (Institute of Electrical and Electronics Engineers, 2010-05)
    We study power control in a multi-cell CDMA wireless system whereby self-interested users share a common spectrum and interfere with each other. Our objective is to design a power control scheme that achieves a (near) ...
  • Schulz, Andreas S.; Uhan, Nelson A. (INFORMS, 2011-02)
    We consider the problem of minimizing the weighted sum of completion times on a single machine subject to bipartite precedence constraints in which all minimal jobs have unit processing time and zero weight, and all maximal ...
