  • Manurangsi, Pasin; Moshkovitz Aaronson, Dana Hadar (Springer US, 2015-11)
    The projection games (aka Label Cover) problem is of great importance to the field of approximation algorithms, since most of the NP-hardness of approximation results we know today are reductions from Label Cover. In this ...
  • Ahn, Jooeun; Hogan, Neville (Public Library of Science, 2015-03)
    Mathematical techniques have provided tools to quantify the stability of rhythmic movements of humans and machines as well as mathematical models. One archetypal example is the use of Floquet multipliers: assuming periodic ...
  • Wong, Liang Jie; Johnson, Steven G.; Kaertner, Franz X. (Optical Society of America, 2014-02)
    We derive an asymptotically accurate formula for the beam waist of ultrashort, tightly focused fundamental linearly polarized, radially polarized, and azimuthally polarized modes in free space. We compute the exact beam ...

    The domestic dog, Canis familiaris, is a well-established model system for mapping trait and disease loci. While the original draft sequence was of good quality, gaps were abundant particularly in promoter regions of the ...
  • Ma, Xiaohua; Hautier, Geoffroy; Jain, Anubhav; Doe, Robert E.; Ceder, Gerbrand (Electrochemical Society, 2012-12)
    We present a layered Li-intercalation oxide that operates on the V[superscript 3+]/V[superscript 4+] redox couple. The stabilization effect of adding a +3 element into the layered LiVO[subscript 2] has been studied by first ...
  • Lee, Hong Geun; Buchwald, Stephen Leffler; Milner, Phillip John (American Chemical Society (ACS), 2013-11)
    The stable Pd(0) species [(1,5-cyclooctadiene)(L·Pd)[subscript 2]] (L = AdBrettPhos) has been prepared and successfully evaluated as a precatalyst for the fluorination of aryl triflates derived from biologically active and ...
  • Kang, Peter K.; Lee, Jonghyun; Lee, Seunghak; Kitanidis, Peter K.; Fu, Xiaojing; Juanes, Ruben (American Geophysical Union, 2017-05)
    Managing recharge of freshwater into saline aquifers requires accurate estimation of the heterogeneous permeability field for maximizing injection and recovery efficiency. Here we present a methodology for subsurface ...
  • Naeser, Margaret A.; Saltmarche, Anita; Krengel, Maxine H.; Hamblin, Michael R.; Knight, Jeffrey A. (Mary Ann Liebert, Inc., 2011-05)
    Objective: Two chronic, traumatic brain injury (TBI) cases, where cognition improved following treatment with red and near-infrared light-emitting diodes (LEDs), applied transcranially to forehead and scalp areas, are ...
  • Boyce, J. W.; Hodges, Kip Vernon; King, D.; Crowley, J. L.; Jercinovic, M.; Chatterjee, Nilanjan; Bowring, Samuel A.; Searle, M. (American Geophysical Union (AGU), 2009-09)
    The newly developed laser microprobe (U-Th)/He thermochronometer permits, for the first time, the ability to generate precise (U-Th)/He cooling ages for even very young (<1 Ma) samples with a spatial resolution on the order ...
  • Terry, James L; Reinke, Matthew Logan; Hughes Jr, Jerry; Labombard, Brian; Theiler, Christian; Wallace, Gregory Marriner; Baek, Seung Gyou; Brunner, Daniel Frederic; Churchill, Randy Michael; Edlund, Eric Matthias; Ennever, Paul Chappell; Faust, Ian Charles; Golfinopoulos, Theodore; Greenwald, Martin J; Hubbard, Amanda E; Irby, James Henderson; Lin, Yijun; Parker, Ronald R; Rice, John E; Shiraiwa, Shunichi; Walk Jr, John R; Wukitch, Stephen James; Xu, Peng (American Institute of Physics (AIP), 2015-05)
    Injecting Lower Hybrid Range of Frequency (LHRF) waves into Alcator C-Mod's high-density H-mode plasmas has led to enhanced global energy confinement by increasing pedestal temperature and pressure gradients, decreasing ...
  • McMurry, Andrew J.; Fitch, Britt; Savova, Guergana; Reis, Ben Y.; Kohane, Isaac (BioMed Central Ltd, 2013-10)
    Background: Physician notes routinely recorded during patient care represent a vast and underutilized resource for human disease studies on a population scale. Their use in research is primarily limited by the need to ...
  • Yang, Yung-Hun; Brigham, Christopher J.; Willis, Laura B.; Rha, ChoKyun; Sinskey, Anthony J. (Springer, 2011-01)
    Extracting polyhydroxyalkanoate (PHA) polymer from bacterial cells often involves harsh conditions, including use of environmentally harmful solvents. We evaluated different detergents under various conditions to extract ...
  • Orosz, Jerome A.; Steiner, James F.; McClintock, Jeffrey E.; Torres, Manuel A. P.; Bailyn, Charles D.; Miller, Jon M.; Remillard, Ronald Alan (IOP Publishing, 2011-03)
    We present an improved dynamical model of the X-ray binary and microquasar XTE J1550–564 based on new moderate-resolution optical spectroscopy and near-infrared photometry obtained with the 6.5 m Magellan Telescopes at Las ...
  • Urban, Karsten; Patera, Anthony T. (American Mathematical Society (AMS), 2013-10)
    We consider a space-time variational formulation for linear parabolic partial differential equations. We introduce an associated Petrov-Galerkin truth finite element discretization with favorable discrete inf-sup constant ...
  • Tsakraklides, Vasiliki; Brevnova, Elena; Shaw, A. Joe; Stephanopoulos, Gregory (Public Library of Science, 2015-07)
    Gene targeting is a challenge in organisms where non-homologous end-joining is the predominant form of recombination. We show that cell division cycle synchronization can be applied to significantly increase the rate of ...
  • Bansal, Mukul S.; Wu, Yi-Chieh; Alm, Eric J.; Kellis, Manolis (Oxford University Press, 2014-12)
    Motivation: The accurate inference of gene trees is a necessary step in many evolutionary studies. Although the problem of accurate gene tree inference has received considerable attention, most existing methods are only ...
