  • Dong, Xi; Zhao, Yue; Freedman, Daniel Z (Springer/SISSA, 2015-06)
    The AdS/CFT correspondence is applied to an analogue of the little hierarchy problem in three-dimensional supersymmetric theories. The bulk is governed by a super-gravity theory in which a U(1) × U(1) R-symmetry is gauged ...
  • Blondel, Vincent D.; Gurbuzbalaban, Mert; Megretski, Alexandre; Overton, Michael L. (Institute of Electrical and Electronics Engineers (IEEE), 2010-12)
    Given a family of real or complex monic polynomials of fixed degree with one fixed affine constraint on their coefficients, consider the problem of minimizing the root radius (largest modulus of the roots) or abscissa ...

  • Petillo, Stephanie; Schmidt, Henrik (Institute of Electrical and Electronics Engineers (IEEE), 2014-01)
    Advances in the fields of autonomy software and environmental sampling techniques for autonomous underwater vehicles (AUVs) have recently allowed for the merging of oceanographic data collection with the testing of emerging ...
  • Herr, Hugh M.; Hofmann, Andreas; Popovic, Marko (Institute of Electrical and Electronics Engineers, 2009-07)
    Recent humanoid control investigations have emphasized the importance of controlling whole-body angular momentum throughout a movement task. For typical movement tasks, such as normal walking, such controllers minimize ...
  • Vasdekis, Andreas E.; Silverman, Andrew Michael; Stephanopoulos, Gregory (Public Library of Science, 2017-01)
    Despite substantial achievements in elucidating the metabolic pathways of lipogenesis, a mechanistic representation of lipid accumulation and degradation has not been fully attained to-date. Recent evidence suggests that ...
  • Cifuentes, Diego Fernando; Parrilo, Pablo A (Society for Industrial and Applied Mathematics, 2016-08)
    Chordal structure and bounded treewidth allow for efficient computation in numerical linear algebra, graphical models, constraint satisfaction, and many other areas. In this paper, we begin the study of how to exploit ...
  • Zhang, Guowei; Horn, Webb H; Sanchez, Daniel (Association for Computing Machinery (ACM), 2015-12)
    We present Coup, a technique to lower the cost of updates to shared data in cache-coherent systems. Coup exploits the insight that many update operations, such as additions and bitwise logical operations, are commutative: ...
  • Grosse, Roger Baker; Salakhutdinov, Ruslan; Freeman, William T.; Tenenbaum, Joshua B. (AUAI Press, 2012-08)
    The recent proliferation of richly structured probabilistic models raises the question of how to automatically determine an appropriate model for a dataset. We investigate this question for a space of matrix decomposition ...
  • McMichael, Joseph G.; Maymon, Shay; Oppenheim, Alan V. (Institute of Electrical and Electronics Engineers (IEEE), 2011-11)
    Uniform quantizers are often modeled as additive uncorrelated noise sources. This paper explores the validity of the additive noise model in the environment of time-interleaved A/D converters. Cross-channel quantizer error ...
  • Robbel, Philipp; Roy, Deb K. (Institute of Electrical and Electronics Engineers, 2010-12)
    This paper describes a new approach to object recognition for active vision systems that integrates information across multiple observations of an object. The approach exploits the order relationship between successive ...
  • Choi, Myung Jin; Lim, Joseph Jaewhan; Torralba, Antonio; Willsky, Alan S. (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
    There has been a growing interest in exploiting contextual information in addition to local features to detect and localize multiple object categories in an image. Context models can efficiently rule out some unlikely ...
  • Ebert, Markus A.; Liebler, Stefan; Tackmann, Frank J.; Tackmann, Kerstin; Zeune, Lisa; Moult, Ian James; Stewart, Iain W (American Physical Society, 2016-09)
    If a new high-mass resonance is discovered at the Large Hadron Collider, model-independent techniques to identify the production mechanism will be crucial to understand its nature and effective couplings to Standard Model ...
  • Dahlburg, Jill; Amatucci, William; Brown, Michael; Chan, Vincent; Chen, James; Cothran, Christopher; Chua, Damien; Dahlburg, Russell; Doschek, George; Egedal-Pedersen, Jan; Forest, Cary; Howard, Russell; Huba, Joseph; Ko, Yuan-Kuen; Krall, Jonathan; Laming, J. Martin; Lin, Robert P.; Linton, Mark; Lukin, Vyacheslav; Murphy, Ronald; Rakowski, Cara; Socker, Dennis; Tylka, Allan; Vourlidas, Angelos; Warren, Harry; Wood, Brian (Molecular Diversity Preservation International, 2010-05)
    Recent advances in space-based heliospheric observations, laboratory experimentation, and plasma simulation codes are creating an exciting new cross-disciplinary opportunity for understanding fast energy release and transport ...
  • Wang, Sheng; Zhai, ChengXiang; Peng, Jian; Cho, Hyunghoon; Berger Leighton, Bonnie (Oxford University Press, 2015-06)
    Motivation: Systematically predicting gene (or protein) function based on molecular interaction networks has become an important tool in refining and enhancing the existing annotation catalogs, such as the Gene Ontology ...
  • Buljan, Hrvoje; Ilic, Ognjen; Kaminer, Ido Efraim; Lahini, Yoav; Soljacic, Marin (American Chemical Society (ACS), 2016-01)
    Conventional methods of manipulating particles with light, such as optical tweezers and optical tractor beams, rely on beam-shaping to realize complex electromagnetic field profiles and are thus sensitive to scattering. ...
  • Zhang, Guowei; Chiu, Virginia; Sanchez, Daniel (Institute of Electrical and Electronics Engineers (IEEE), 2016-12)
    Hardware speculative execution schemes such as hardware transactional memory (HTM) enjoy low run-time overheads but suffer from limited concurrency because they rely on reads and writes to detect conflicts. By contrast, ...
  • Schwarz, J. P.; Spackman, J. R.; Perring, A. E.; Coe, H.; Liu, D.; Clarke, A. D.; Wang, Xuan; Heald, Colette L.; Ridley, David Andrew (Copernicus GmbH, 2014-10)
    Atmospheric black carbon (BC) is a leading climate warming agent, yet uncertainties on the global direct radiative forcing (DRF) remain large. Here we expand a global model simulation (GEOS-Chem) of BC to include the ...
  • Choi, Myung Jin; Chandrasekaran, Venkat; Willsky, Alan S. (Association for Computing Machinery / ACM Digital Library, 2009-06)
    We consider Gaussian multiresolution (MR) models in which coarser, hidden variables serve to capture statistical dependencies among the finest scale variables. Tree-structured MR models have limited modeling capabilities, ...
  • Kirmani, Ahmed; Colaco, Andrea B.; Wong, Franco N. C.; Goyal, Vivek K. (Optical Society of America, 2011-10)
    Range acquisition systems such as light detection and ranging (LIDAR) and time-of-flight (TOF) cameras operate by measuring the time difference of arrival between a transmitted pulse and the scene reflection. We introduce ...
