  • Mulligan, Michael (American Physical Society, 2011-05)
    We study how the θ [theta] term is affected by interactions in certain one-dimensional gapped systems that preserve charge conjugation, parity, and time-reversal invariance. We exploit the relation between the chiral anomaly ...
  • Smithwick, Quinn Y. J.; Barabas, James D.; Smalley, Daniel E.; Bove, V. Michael, Jr. (SPIE, 2010-02)
    Image-based holographic stereogram rendering methods for holographic video have the attractive properties of moderate computational cost and correct handling of occlusions and translucent objects. These methods are also ...
  • Kiryati, Nahum; Ben-Zadok, Nir; Riklin-Raviv, Tammy (Institute of Electrical and Electronics Engineers, 2009-08)
    Image-guided therapy procedures require the patient to remain still throughout the image acquisition, data analysis and therapy. This imposes a tight time constraint on the over-all process. Automatic extraction of the ...
  • Kewlani, Gaurav; Iagnemma, Karl; Horner, David A.; Jones, Randolph A.; Cummins, Christopher L.; Toschlog, Matthew; Crawford, Justin; Rohde, Mitchell M. (SPIE, 2009-04)
    It is widely recognized that simulation is pivotal to vehicle development, whether manned or unmanned. There are few dedicated choices, however, for those wishing to perform realistic, end-to-end simulations of unmanned ...
  • Paluska, Justin Mazzola; Pham, Hubert (Institute of Electrical and Electronic Engineers, 2010-03)
    We present ChunkStream, a system for efficient streaming and interactive editing of online video. Rather than using a specialized protocol and stream format, ChunkStream makes use of a generic mechanism employing chunks. ...
  • Thompson, R. L.; Dlugokencky, E.; Chevallier, F.; Ciais, P.; Dutton, G.; Elkins, J. W.; Langenfelds, R. L.; Prinn, Ronald G.; Weiss, R. F.; Tohjima, Y.; O'Doherty, S.; Krummel, P. B.; Fraser, P.; Steele, L. P. (American Geophysical Union, 2013-08)
    Observations of tropospheric N2O mixing ratio show significant variability on interannual timescales (0.2 ppb, 1 standard deviation). We found that interannual variability in N2O is weakly correlated with that in CFC-12 ...
  • Iyer, Rajkamal; Peydro, Jose-Luis; da-Rocha-Lopes, Samuel; Schoar, Antoinette (Oxford University Press on behalf of The Society for Financial Studies, 2013-10)
    We study the credit supply effects of the unexpected freeze of the European interbank market, using exhaustive Portuguese loan-level data. We find that banks that rely more on interbank borrowing before the crisis decrease ...
  • Moon, James J.; Suh, Heikyung; Bershteyn, Anna; Stephan, Matthias T.; Liu, Haipeng; Huang, Bonnie; Sohail, Mashaal; Luo, Samantha; Ho Um, Soong; Khant, Htet; Goodwin, Jessica T.; Ramos, Jenelyn; Chiu, Wah; Irvine, Darrell J. (Nature Publishing Group, 2011-02)
    Vaccines based on recombinant proteins avoid the toxicity and antivector immunity associated with live vaccine (for example, viral) vectors, but their immunogenicity is poor, particularly for CD8+ T-cell responses. Synthetic ...
  • Ploegh, Hidde; Saha, Anjan K.; Kappes, Ferdinand; Mundade, Amruta; Deutzmann, Anja; Rosmarin, David M.; Legendre, Maureen; Chatain, Nicolas; Al-Obaidi, Zeina; Adams, Barbara S.; Ferrando-May, Elisa; Mor-Vaknin, Nirit; Markovitz, David M. (National Academy of Sciences (U.S.), 2013-04)
    DEK is a biochemically distinct, conserved nonhistone protein that is vital to global heterochromatin integrity. In addition, DEK can be secreted and function as a chemotactic, proinflammatory factor. Here we show that ...
  • Ridley, David Andrew (Copernicus GmbH, 2014-05)
    Many of the next generation of global climate models will include aerosol schemes which explicitly simulate the microphysical processes that determine the particle size distribution. These models enable aerosol optical ...
  • Horn, Berthold Klaus Paul (Taylor & Francis, 2010-06)
    It is well known that a function can be decomposed uniquely into the sum of an odd and an even function. This notion can be extended to the unique decomposition into the sum of four functions – two of which are even and ...
  • DeLong, Edward (BioMed Central Ltd, 2010-05)
    Population metagenomics reveals the reduced metabolic capacities of a marine nitrogen-fixing cyanobacterium that lacks many of the signature features of typical cyanobacteria.
  • Macbeth, Jamie C.; Cummings, M. L.; Bertuccelli, Luca F.; Surana, Amit (Human Factors and Ergonomics Society, 2012-10)
    While there is currently significant interest in developing Unmanned Aerial Systems (UASs) that can be supervised by a single operator, the majority of these systems focus on Intelligence, Surveillance, and Reconnaissance ...
  • Park, Hyesung; Chang, Sehoon; Smith, Matthew; Gradečak, Silvija; Kong, Jing (Nature Publishing Group, 2013-04)
    The high transparency of graphene, together with its good electrical conductivity and mechanical robustness, enable its use as transparent electrodes in optoelectronic devices such as solar cells. While initial demonstrations ...
  • Shaw, George M.; Roy, Deb K. (2011-08)
    This work details methods for visualizing and browsing a set of distributions of locational data derived from multi-modal analysis of a large video and audio dataset.
  • Zhao, Benzhong; MacMinn, Christopher W.; Szulczewski, Michael Lawrence; Neufeld, Jerome A.; Huppert, Herbert E.; Juanes, Ruben (American Physical Society, 2013-02)
    We study the gravity-exchange flow of two immiscible fluids in a porous medium and show that, in contrast with the miscible case, a portion of the initial interface remains pinned at all times. We elucidate, by means of ...

  • Caglar, Tolga; Berker, A. Nihat (American Physical Society, 2011-11)
    The roughening phase diagram of the d=3 Ising model with uniaxially anisotropic interactions is calculated for the entire range of anisotropy, from decoupled planes to the isotropic model to the solid-on-solid model, using ...
  • Kolpak, Alexie M.; Ismail-Beigi, S. (American Physical Society, 2012-05)
    Phenomenological models suggest that thin epitaxial SrTiO[subscript 3] films on silicon will exhibit ferroelectric behavior as a result of compressive strain. However, such models do not include atomic-scale interface ...
  • Emori, Satoru; Bono, David C.; Beach, Geoffrey Stephen (American Institute of Physics, 2012-07)
    Current-driven domain wall (DW) motion is investigated in Pt/Co/GdOx nanostrips with perpendicular magnetic anisotropy. Measurements of the propagation field and the energy barrier for thermally activated DW motion reveal ...
