  • Li, Nan (Springer US, 2013-09)
    We study the problem of expanding the product of two Stanley symmetric functions F[subscript w]⋅F[subscript u] into Stanley symmetric functions in some natural way. Our approach is to consider a Stanley symmetric function ...
  • Naseer, Usman (Springer Berlin Heidelberg, 2015-10)
    We provide the canonical formulation of double field theory. It is shown that this dynamics is subject to primary and secondary constraints. The Poisson bracket algebra of secondary constraints is shown to close on-shell ...
  • Kleiman, Steven L.; Vidal Martins, Renato (Springer, 2009-04)
    We give re fined statements and modern proofs of Rosenlicht's re- sults about the canonical model C′ of an arbitrary complete integral curve C. Notably, we prove that C and C′ are birationally equivalent if and only if ...
  • Ehinger, Krista A.; Oliva, Aude (Cognitive Science Society, Inc., 2011-07)
    When recognizing or depicting objects, people show a preference for particular “canonical” views. Are there similar preferences for particular views of scenes? We investigated this question using panoramic images, which show ...
  • Burgess, Robin; Donaldson, David John (2010-05)
    A weakening dependence on rain-fed agriculture has been a hallmark of the economic transformation of countries throughout history. Rural citizens in developing countries today, however, remain highly exposed to ...
  • Sheshadri, Aditi; Plumb, R. Alan; Domeisen, Daniela I. V. (American Meteorological Society, 2014-02)
    The authors test the hypothesis that recent observed trends in surface westerlies in the Southern Hemisphere are directly consequent on observed trends in the timing of stratospheric final warming events. The analysis ...
  • Vanderploeg, Eric J.; Grodzinsky, Alan J. (Elsevier Ltd., 2009-05)
    It is well understood that proper joint kinematics and loading are important factors in maintaining the health of the articular cartilage of the knee. This state of normal, physiologic loading facilitates a balance between ...
  • Datar, Ram; Kim, Seonghwan; Jeon, Sangmin; Hesketh, Peter; Manalis, Scott R.; Boisen, Anja; Thundat, Thomas (Cambridge University Press, 2009-06)
    Cantilever sensors have attracted considerable attention over the last decade because of their potential as a highly sensitive sensor platform for high throughput and multiplexed detection of proteins and nucleic acids. A ...
  • Semino, Carlos E. (Hindawi Publishing Corporation, 2003)
    Animals carry stem cells throughout their entire life, from embryogenesis to senescence. Their function during development and adulthood consists basically of forming and sustaining functional tissues while maintaining a ...
  • Nocera, Daniel G. (MIT Press, 2012-07)
    Energy demand in the twenty-first century will be driven by the needs of three billion people in the emerging world and three billion new inhabitants to our planet. To provide them with a renewable and sustainable energy ...
  • Levitov, Leonid; Young, Andrea F. (American Physical Society (APS), 2011-08)
    The unique capabilities of capacitance measurements in bilayer graphene enable probing of layer-specific properties that are normally out of reach in transport measurements. Furthermore, capacitance measurements in the ...
  • Lloyd, Seth; Giovannetti, Vittorio; Lupo, Cosmo; Mancini, Stefano; Pirandola, Stefano (American Physical Society, 2012-06)
    A wide variety of communication channels employ the quantized electromagnetic field to convey information. Their communication capacity crucially depends on losses associated to spatial characteristics of the channel such ...
  • Schafer, Joachim; Daems, David; Karpov, Evgueni; Cerf, Nicolas J. (American Physical Society, 2009-12)
    We address the classical capacity of a quantum bosonic memory channel with additive noise, subject to an input energy constraint. The memory is modeled by correlated noise emerging from a Gauss-Markov process. Under ...
  • Mitter, Sanjoy K.; Tatikonda, Sekhar (Institute of Electrical and Electronics Engineers, 2008-12)
    In this paper, we introduce a general framework for treating channels with memory and feedback. First, we prove a general feedback channel coding theorem based on Massey's concept of directed information. Second, we present ...
  • Como, Giacomo; Fagnani, Fabio (Institute of Electrical and Electronics Engineers, 2009-04)
    The capacity of finite Abelian group codes over symmetric memoryless channels is determined. For certain important examples, such as m -PSK constellations over additive white Gaussian noise (AWGN) channels, with m a prime ...
  • Leung, Debbie W.; Lim, Joungkeun; Shor, Peter W. (American Physical Society, 2009-11)
    We present a communication protocol for the erasure channel assisted by backward classical communication, which achieves a significantly better rate than the best prior result. In addition, we prove an upper bound for the ...
  • Prabhakaran, Vivek; Rypma, Bart; Narayanan, Nandakumar S.; Meier, Timothy B.; Austin, Benjamin P.; Nair, Veena A.; Naing, Lin; Thomas, Lisa E.; Gabrieli, John D. E. (Public Library of Science, 2011-11)
    Working memory (WM) capacity and WM processing speed are simple cognitive measures that underlie human performance in complex processes such as reasoning and language comprehension. These cognitive measures have shown to ...
  • Castleberry, Steven A.; Li, Wei; Deng, Di; Hammond, Paula T.; Mayner, Sarah E. (American Chemical Society (ACS), 2014-05)
    Layer-by-layer (LbL) assembly is a powerful tool with increasing real world applications in energy, biomaterials, active surfaces, and membranes; however, the current state of the art requires individual sample construction ...
  • Holtzman, Ran; Juanes, Ruben; Szulczewski, Michael Lawrence (American Physical Society, 2012-06)
    We study the displacement of immiscible fluids in deformable, noncohesive granular media. Experimentally, we inject air into a thin bed of water-saturated glass beads and observe the invasion morphology. The control ...
  • Frolov, Timofey; Carter, W. Craig; Asta, Mark (American Chemical Society (ACS), 2014-05)
    In this study, we present atomistic simulations and theoretical analyses that reveal a capillary instability that is intrinsic to wetting geometries characteristic of the vapor–liquid–solid mechanism for nanowire growth. ...
