  • 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 ...

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 ...
  • 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 ...
  • Jiang, Hai; Hemann, Michael; Yaffe, Michael B.; Reinhardt, H. Christian (Landes Bioscience, 2009-10)
    Emerging data suggests that synthetic lethal interactions between mutated oncogenes/tumor suppressor genes and molecules involved in DNA damage signaling and repair can be therapeutically exploited to preferentially kill ...
  • Meuler, Adam J.; McKinley, Gareth H.; Cohen, Robert E. (American Chemical Society (ACS), 2010-12)
    Appropriately structured topographical features that are found in nature (e.g,, the lotus leaf) or that are produced synthetically (e.g., via lithography) can impart superhydrophobic properties to surfaces. Water beads up ...
  • Imperiali, Barbara; Jaffee, Marcie Beth (American Chemical Society (ACS), 2011-08)
    The central enzyme in N-linked glycosylation is the oligosaccharyl transferase (OTase), which catalyzes glycan transfer from a polyprenyldiphosphate-linked carrier to select asparagines within acceptor proteins. PglB from ...
  • Deng, D. S.; Nave, Jean-Christophe; Liang, X.; Johnson, Steven G.; Fink, Yoel (Optical Society of America, 2011-08)
    A new class of multi-material fiber that incorporates micrometer-thickness concentric-cylindrical sheets of glass into polymer matrix has emerged. The ultimate lower limit of feature size and recent observation of interesting ...
  • Calmon, Flavio P.; Varia, Mayank; Medard, Muriel (Institute of Electrical and Electronics Engineers (IEEE), 2014-11)
    The principal inertia components of the joint distribution of two random variables X and Y are inherently connected to how an observation of Y is statistically related to a hidden variable X. In this paper, we explore this ...
  • Honda, Tomonori; Ciucci, Francesco; Kansara, Saket; Lewis, Kemper E.; Yang, Maria (American Institute of Aeronautics and Astronautics (AIAA), 2010-09)
    The process of designing large engineering systems can involve extensive sharing of resources among many competing subsystems. These resources may be represented as design parameters that are shared between the system ...
  • Hoffman, N. M.; Amendt, P. A.; Atzeni, S.; Glebov, V. Yu.; Stoeckl, C.; Seka, W.; Marshall, F. J.; Delettrez, J. A.; Sangster, T. C.; Betti, R.; Goncharov, V. N.; Meyerhofer, D.

(American Physical Society, 2014-05)
    Clear evidence of the transition from hydrodynamiclike to strongly kinetic shock-driven implosions is, for the first time, revealed and quantitatively assessed. Implosions with a range of initial equimolar D[superscript ...
  • Marshall, John C.; Enderton, Daniel (American Meteorological Society, 2008-07)
    The degree to which total meridional heat transport is sensitive to the details of its atmospheric and oceanic components is explored. A coupled atmosphere, ocean, and sea ice model of an aquaplanet is employed to simulate ...
  • Zhao, Fang; Camara Pereira, Francisco; Ball, Rudi; Kim, Youngsung; Han, Yafei; Zegras, P. Christopher; Ben-Akiva, Moshe E. (Transportation Research Board of the National Academies, 2015-01)
    Future Mobility Sensing (FMS) is an innovative smartphone-based travel survey system that was field tested in 2012/2013 together with the Household Interview Travel Survey (HITS) in Singapore. This paper presents findings ...
