  • 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 ...
  • 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; 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 ...
  • 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, J.-C.; 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 ...
  • 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. D.; Skupsky, S.; Bellei, C.; Pino, J.; Wilks, S. C.; Kagan, G.; Molvig, K.; Nikroo, A.; Rosenberg, Michael Jonathan; Rinderknecht, Hans George; Zylstra, Alex Bennett; Li, Chikang; Seguin, Fredrick Hampton; Sio, Hong Weng; Gatu Johnson, Maria; Frenje, Johan A.; Petrasso, Richard 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 ...
  • Lashkari, Danial; Golland, Polina (Springer Berlin / Heidelberg, 2009-07)
    We present an exploratory method for simultaneous parcellation of multisubject fMRI data into functionally coherent areas. The method is based on a solely functional representation of the fMRI data and a hierarchical ...
  • Prinn, Ronald G.; Nevison, C. D.; Dlugokencky, E.; Dutton, G.; Elkins, J. W.; Fraser, P.; Hall, B.; Krummel, P. B.; Langenfelds, R. L.; O'Doherty, S.; Steele, L. P.; Weiss, R. F. (European Geosciences Union, 2011-04)
    Seasonal cycles in the mixing ratios of tropospheric nitrous oxide (N[subscript 2]O) are derived by detrending long-term measurements made at sites across four global surface monitoring networks. The detrended monthly data ...
  • Liu, Ce; Sharan, Lavanya; Adelson, Edward H.; Rosenholtz, Ruth (Institute of Electrical and Electronics Engineers, 2010-08)
    We are interested in identifying the material category, e.g. glass, metal, fabric, plastic or wood, from a single image of a surface. Unlike other visual recognition tasks in computer vision, it is difficult to find good, ...
  • Venkataraman, Archana; Van Dijk, Koene R. A.; Buckner, Randy L.; Golland, Polina (Institute of Electrical and Electronics Engineers, 2009-04)
    In this paper we investigate the use of data driven clustering methods for functional connectivity analysis in fMRI. In particular, we consider the k-means and spectral clustering algorithms as alternatives to the commonly ...
  • Tulloch, Ross; Marshall, John C. (American Meteorological Society, 2012-06)
    Multidecadal variability in the Atlantic meridional overturning circulation (AMOC) of the ocean is diagnosed in the NCAR Community Climate System Model, version 3 (CCSM3), and the GFDL Coupled Model (CM2.1). Common diagnostic ...
  • Musch, B. U.; Hagler, Ph.; Negele, John W.; Schafer, A. (American Physical Society, 2011-05)
    We discuss in detail a method to study transverse momentum dependent parton distribution functions (TMDs) using lattice QCD. To develop the formalism and to obtain first numerical results, we directly implement a bilocal ...
  • Hughes, Scott A; Nissanke, Samaya; Holz, Daniel E.; Dalal, Neal; Sievers, Jonathan L. (Institute of Physics ; American Astronomical Society., 2010-11)
    Recent observations support the hypothesis that a large fraction of "short-hard" gamma-ray bursts (SHBs) are associated with the inspiral and merger of compact binaries. Since gravitational-wave (GW) measurements of ...
