  • 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 ...
  • Miller, J. M.; Markoff, Sera B.; Rupen, M. P.; Maitra, D.; Nowak, Michael A. (IOP Publishing, 2010-08)
    We report on a year-long effort to monitor the central supermassive black hole in M81 in the X-ray and radio bands. Using Chandra and the Very Large Array, we obtained quasi-simultaneous observations of M81* on seven ...
  • Prinn, Ronald G.; Nevison, C. D.; Dlugokencky, E.; Dutton, G. S.; Elkins, J. W.; Fraser, P. J.; Hall, B. D.; Krummel, P. B.; Langenfelds, R. L.; O'Doherty, Simon; 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 ...
  • Anteraper, Sheeba Arnold; Keil, Boris; Triantafyllou, Christina; Gabrieli, Susan; Shannon, Steven P.; Gabrieli, John D. E. (Mary Ann Liebert, 2013-05)
    The use of multichannel array head coils in functional and structural magnetic resonance imaging (MRI) provides increased signal-to-noise ratio (SNR), higher sensitivity, and parallel imaging capabilities. However, their ...
  • Alexander, Kathleen C.; Schuh, Christopher A. (Elsevier, 2013-02)
    To develop a structure–kinetic property mapping for grain boundaries requires an understanding of their energy landscapes, i.e. the energy basins and nearby saddle points separating adjacent structures. We implement the ...
  • Orlikowski, Wanda J.; Scott, Susan V. (Wiley Blackwell, 2014-12)
    Our intent in this commentary is to support the turn to materiality in organizational research, and contribute to it by considering some differences in our approach from that proposed by Hardy and Thomas. Drawing on agential ...
  • 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 ...
  • Haslanger, Sally (2009)
    Josh Glasgow’s book A Theory of Race (2009) presents an important argument for the claim that race is an illusion and, that racial claims are, strictly speaking, false. They are false because the concept of race, according ...
  • Hughes, Scott A.; Nissanke, Samaya M.; 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 ...
  • Picard, Rosalind W.; Lane, Joseph K.; El Kaliouby, Rana; Goodwin, Matthew; Hoque, Mohammed Ehasanul (International Speech Communication Association, 2009-09)
    Individuals on the autism spectrum often have difficulties producing intelligible speech with either high or low speech rate, and atypical pitch and/or amplitude affect. In this study, we present a novel intervention towards ...
  • Picard, Rosalind W.; McDuff, Daniel Jonathan; Hoque, Mohammed Ehasanul (Institute of Electrical and Electronics Engineers (IEEE), 2012-04)
    We create two experimental situations to elicit two affective states: frustration, and delight. In the first experiment, participants were asked to recall situations while expressing either delight or frustration, while ...
  • Machado, Daniel; Costa, Rafael S.; Rocha, Isabel; Tidor, Bruce; Ferreira, Eugenio C. (Elsevier, 2012-01)
    Systems biology provides new approaches for metabolic engineering through the development of models and methods for simulation and optimization of microbial metabolism. Here we explore the relationship between two modeling ...
  • Lee, Hyomin; Rubner, Michael F.; McKinley, Gareth H.; Cohen, Robert E.; Kleingartner, Justin Alan (Royal Society of Chemistry, 2013-05)
    Switchable polymer multilayer coatings consisting of poly(vinyl alcohol) (PVA) and poly(acrylic acid) (PAA) were prepared via Layer-by-Layer (LbL) assembly and post-functionalized with poly(ethylene glycol methyl ether) ...
  • Abin-Fuentes, Andres; Mohamed, Magdy El-Said; Wang, Daniel I.; Prather, Kristala L. Jones (American Society for Microbiology, 2013-10)
    Microbial desulfurization, or biodesulfurization (BDS), of fuels is a promising technology because it can desulfurize compounds that are recalcitrant to the current standard technology in the oil industry. One of the ...
  • Hansen, T.; Hansen, C. J.; Christlieb, N.; Yong, D.; Bessell, M. S.; Beers, Timothy C.; Placco, V. M.; Norris, J. E.; Asplund, M.; Frebel, Anna L.; Garcia Perez, A. E. (IOP Publishing, 2014-05)
    We present an elemental abundance analysis for four newly discovered ultra metal-poor stars from the Hamburg/ESO survey, with [Fe/H] ≤ –4. Based on high-resolution, high signal-to-noise spectra, we derive abundances for ...
  • Dekker, Job; Marti-Renom, Marc A.; Mirny, Leonid A. (Nature Publishing Group, 2013-05)
    How DNA is organized in three dimensions inside the cell nucleus and how this affects the ways in which cells access, read and interpret genetic information are among the longest standing questions in cell biology. Using ...
  • Allegrini, F.; Bzowski, M.; Dayeh, M. A.; DeMajistre, R.; Desai, M. I.; Funsten, H. O.; Fuselier, S. A.; Janzen, Paul H.; Kubiak, M. A.; McComas, David J.; Reisenfeld, D. B.; Schwadron, N.; Vanderspek, Roland K. (IOP Publishing, 2012-04)
    The Interstellar Boundary Explorer (IBEX) has observed energetic neutral atom (ENA) hydrogen emissions from the edge of the solar system for more than three years. The observations span energies from 0.01 to 6 keV FWHM. ...
