  • Greytak, Matthew B.; Hover, Franz S. (Institute of Electrical and Electronics Engineers, 2009-07)
    Path planning algorithms that incorporate risk and uncertainty need to be able to predict the evolution of path-following error statistics for each candidate plan. We present an analytic method to predict the evolving error ...
  • Cerfon, A. J.; Freidberg, Jeffrey P.; Parra Fabian, Ignacio Esteban; Antaya, T. A. (American Physical Society, 2013-02)
    Using a two-dimensional fluid description, we investigate the nonlinear radial-longitudinal dynamics of intense beams in isochronous cyclotrons in the nonrelativistic limit. With a multiscale analysis separating the time ...
  • Balasubramanian, Koushik; McGreevy, John (American Physical Society, 2009-11)
    A Lifshitz point is described by a quantum field theory with anisotropic scale invariance (but not Galilean invariance). In 8, gravity duals were conjectured for such theories. We construct analytically a black hole that ...
  • Falcao-Filho, Edilson L.; Gkortsas, Vasileios-Marios; Kaertner, Franz X.; Gordon, Ariel (Optical Society of America, 2009-06)
    Closed form expressions for the high harmonic generation (HHG) conversion efficiency are obtained for the plateau and cutoff regions. The presented formulas eliminate most of the computational complexity related to HHG ...
  • Pelletier, Jon D.; Perron, J. Taylor (American Geophysical Union (AGU), 2012-05)
    The geomorphic literature contains many analytic solutions for the topographic evolution of gently sloping soil-mantled hillslopes responding to base level changes. Most of these solutions are limited to vertical base level ...
  • Pires, R.; Repp, M.; Ulmanis, J.; Kuhnle, E. D.; Tiecke, T. G.; Greene, Chris H.; Ruzic, Brandon P.; Bohn, John L.; Tiemann, E.; Weidemuller, M. (American Physical Society, 2014-07)
    We provide a comprehensive comparison of a coupled channel calculation, the asymptotic bound-state model (ABM), and the multichannel quantum defect theory (MQDT). Quantitative results for [superscript 6]Li-[superscript ...
  • Johnson, Kristine Dianne; Simchi-Levi, David; Sun, Peng (Institute for Operations Research and the Management Sciences (INFORMS), 2014-06)
    Scrip systems provide a nonmonetary trade economy for exchange of resources. We model a scrip system as a stochastic game and study system design issues on selection rules to match potential trade partners over time. We ...
  • Chakrabarti, Ayan; Zickler, Todd; Freeman, William T. (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
    Blur is caused by a pixel receiving light from multiple scene points, and in many cases, such as object motion, the induced blur varies spatially across the image plane. However, the seemingly straight-forward task of ...
  • Custo, Anna; Boas, David A.; Tsuzuki, Daisuke; Dan, Ippeita; Mesquita, Rickson; Fischl, Bruce; Grimson, W. Eric L.; Wells, William M. (Elsevier, 2009-07)
    We describe a neuroimaging protocol that utilizes an anatomical atlas of the human head to guide diffuse optical tomography of human brain activation. The protocol is demonstrated by imaging the hemodynamic response to ...
  • Koldewyn, Kami; Reynolds, Gretchen; Saygin, Zeynep M.; Osher, David E.; Gabrieli, John D. E.; Saxe, Rebecca R. (Nature Publishing Group, 2011-12)
    A fundamental assumption in neuroscience is that brain structure determines function. Accordingly, functionally distinct regions of cortex should be structurally distinct in their connections to other areas. We tested this ...
  • Coleman, Jason E.; Law, Karen; Bear, Mark (Elsevier B.V., 2009-03)
    Ocular dominance (OD) plasticity is a classic paradigm for studying the effect of experience and deprivation on cortical development, and is manifested as shifts in the relative strength of binocular inputs to primary ...
  • Yendiki, Anastasia; Stevens, Allison; Augustinack, Jean; Salat, David; Zollei, Lilla; Fischl, Bruce (Institute of Electrical and Electronics Engineers (IEEE), 2009-08)
    We investigate the use of anatomical priors in a Bayesian framework for diffusion tractography. We compare priors that utilize different types of information on the white-matter pathways to be reconstructed. This information ...
  • McGee, Sasha; Mardirossian, Vartan; Elackattu, Alphi; Mirkovic, Jelena; Pistey, Robert; Gallagher, George; Kabani, Sadru; Yu, Chung-Chieh; Wang, Zimmern; Badizadegan, Kamran; Grillone, Gregory; Feld, Michael S. (Annals Publishing Company, 2009-11)
    OBJECTIVES: We used reflectance and fluorescence spectroscopy to noninvasively and quantitatively distinguish benign from dysplastic/malignant oral lesions. We designed diagnostic algorithms to account for differences in ...
  • Samson, Leona D.; Begley, Thomas J.; Lahue, Robert S.; Daee, Danielle L.; Fry, Rebecca C.; Erlich, Rachel L. (Public Library of Science, 2008-11)
  • Pickrell, Joseph K.; Patterson, Nick; Loh, Po-Ru; Lipson, Mark; Berger, Bonnie; Stoneking, Mark; Pakendorf, Brigitte; Reich, David (National Academy of Sciences (U.S.), 2014-02)
    The history of southern Africa involved interactions between indigenous hunter–gatherers and a range of populations that moved into the region. Here we use genome-wide genetic data to show that there are at least two ...
  • Williams, Bret R.; Amon, Angelika B. (American Association for Cancer Research, 2009-07)
    Aneuploidy is a characteristic of cancer, with greater than 90% of all solid tumors in humans carrying an aberrant karyotype. Yet, whether or how this condition contributes to tumorigenesis is not understood. Here we ...
  • Sheltzer, Jason Meyer; Blank, Heidi Marie; Pfau, Sarah Jeanne; Tange, Yoshie; George, Benson M.; Humpton, Timothy J.; Brito, Ilana L.; Hiraoka, Yasushi; Niwa, Osami; Amon, Angelika B. (American Association for the Advancement of Science, 2011-08)
    Aneuploidy decreases cellular fitness, yet it is also associated with cancer, a disease of enhanced proliferative capacity. To investigate one mechanism by which aneuploidy could contribute to tumorigenesis, we examined ...
  • Thorburn, Rebecca Ruth; Gonzalez, Christian; Brar, Gloria A.; Christen, Stefan; Carlile, Thomas M.; Ingolia, Nicholas T.; Sauer, Uwe; Weissman, Jonathan S.; Amon, Angelika B. (American Society for Cell Biology, 2013-03)
    Aneuploidy, a chromosome content that is not a multiple of the haploid karyotype, is associated with reduced fitness in all organisms analyzed to date. In budding yeast aneuploidy causes cell proliferation defects, with ...
  • Oromendia, Ana Belen; Amon, Angelika B. (Company of Biologists, 2014-01)
    It has long been appreciated that aneuploidy – in which cells possess a karyotype that is not a multiple of the haploid complement – has a substantial impact on human health, but its effects at the subcellular level have ...
  • Ploegh, Hidde; Maehr, Rene; Greer, Paul L.; Hanayama, Rikinari; Bloodgood, Brenda L.; Mardinly, Alan R.; Lipton, David M.; Flavell, Steven W.; Kim, Tae-Kyung; Griffith, Eric C.; Waldon, Zachary; Chowdhury, Shoaib; Worley, Paul F.; Steen, Judith; Greenberg, Michael E. (Elsevier, 2010-03)
    Angelman Syndrome is a debilitating neurological disorder caused by mutation of the E3 ubiquitin ligase Ube3A, a gene whose mutation has also recently been associated with autism spectrum disorders (ASDs). The function of ...
