  • Ercolessi, Elisa; Franchini, Fabio; Evangelisti, Stefano; Ravanini, Francesco (American Physical Society, 2012-03)
    We study analytically the corrections to the leading terms in the Rényi entropy of a massive lattice theory, showing significant deviations from naive expectations. In particular, we show that finite size and finite mass ...
  • Pirandola, Stefano; Serafini, Alessio; Lloyd, Seth (American Physical Society, 2009-05)
    We present a detailed analysis of all the algebraic conditions an arbitrary 4×4 symmetric matrix must satisfy in order to represent the correlation matrix of a two-mode bosonic system. Then, we completely clarify when this ...
  • Veronika, Merlin; Welsch, Roy E.; Ng, Alvin; Matsudaira, Paul T.; Rajapakse, Jagath (Springer (Biomed Central Ltd.), 2011-11)
    Background: Essential events of cell development and homeostasis are revealed by the associated changes of cell morphology and therefore have been widely used as a key indicator of physiological states and molecular ...

  • Zhou, Xiang; Lu, Ming-Yen; Lu, Yu-Jung; Gwo, Shangjr; Gradecak, Silvija (American Institute of Physics (AIP), 2013-06)
    We report the nanoscale optical investigation of a single GaN p-n junction nanorod by cathodoluminescence (CL) in a scanning transmission electron microscope. CL emission characteristic of dopant-related transitions was ...
  • Lohmeyer, Whitney Quinne; Cahoy, Kerri; Baker, Daniel (Aerospace Research Central, 2012-09)
    We correlate on-orbit component telemetry data from seven Inmarsat geostationary communications satellites from 1996 to 2012 with historical space weather information. We specifically utilize data from the Geostationar ...
  • Gillen, Jonathon Isaiah; Huang, Wujie; Ketterle, Wolfgang; Keshet, Aviv; Su, Edward Joseph; Sanner, Christian Burkhard (American Physical Society, 2012-06)
    A degenerate Fermi gas is rapidly quenched into the regime of strong effective repulsion near a Feshbach resonance. The spin fluctuations are monitored using speckle imaging and, contrary to several theoretical predictions, ...
  • Tieu, Kinh Han; Wang, Xiaogang; Grimson, William E. (Institute of Electrical and Electronics Engineers, 2009-11)
    We propose a novel approach for activity analysis in multiple synchronized but uncalibrated static camera views. In this paper, we refer to activities as motion patterns of objects, which correspond to paths in far-field ...
  • Sokolov, Andrei P.; Stone, Peter H.; Forest, Chris E.; Prinn, Ronald G.; Sarofim, M. C.; Webster, Mort David; Paltsev, Sergey; Schlosser, C. A.; Kicklighter, D.; Dutkiewicz, Stephanie; Wang, Chien; Felzer, B.; Melillo, J. M.; Jacoby, Henry D.; Reilly, John M. (American Meteorological Society, 2009-12)
    The simulations with economic uncertainty discussed in section 4b of Sokolov et al. (2009) were, by mistake, carried out with the mean values of the input climate parameters instead of the intended median values. While ...
  • Filipsson, H. L.; Bernhard, J. M.; Lincoln, Sara Ann; McCorkle, D. C. (Copernicus Publications on behalf of the European Geosciences Union, 2011-06)
    In the paper “A culture-based calibration of benthic foraminiferal paleotemperature proxies: 18O and Mg/Ca results” by H. L. Filipsson et al. (Biogeosciences 7, 1335– 1347, doi:10.5194/bg-7-1335-2010, 2010) Fig. 4 was ...
  • Hisaka, Takayuki; Sasaki, Hajime; Nogami, Yoichi; Hosogi, Kenji; Yoshida, Naohito; Villanueva, Anita A.; del Alamo, Jesus A.; Hasegawa, Shigehiko; Asahi, Hajime (Elsevier, 2009-08)
    We have comprehensively investigated the degradation mechanism of AlGaAs/InGaAs pseudomorphic high-electron-mobility transistors (PHEMTs) under operation in high humidity conditions. PHEMTs degradation under high humidity ...
  • Olken, Benjamin A.; Pande, Rohini (Annual Reviews, 2012-04)
    Recent years have seen a remarkable expansion in economists' ability to measure corruption. This in turn has led to a new generation of well-identified, microeconomic studies. We review the evidence on corruption in ...
  • Kumar, S.; Black, S. J.; Hultman, R.; Szabo, S. T.; DeMaio, K. D.; Du, J.; Katz, B. M.; Covington, H. E.; Dzirasa, K.; Feng, Guoping (Society for Neuroscience, 2013-01)
    Transcranial magnetic stimulation and deep brain stimulation have emerged as therapeutic modalities for treatment refractory depression; however, little remains known regarding the circuitry that mediates the therapeutic ...
  • Shi, Feng; Yap, Pew-Thian; Fan, Yong; Cheng, Jie-Zhi; Wald, Lawrence; Gerig, Guido; Lin, Weili; Shen, Dinggang (Institute of Electrical and Electronics Engineers, 2009-08)
    The acquisition of high quality MR images of neonatal brains is largely hampered by their characteristically small head size and low tissue contrast. As a result, subsequent image processing and analysis, especially for ...
  • Rajendran, Niranjini; Busa, Evelina; Augustinack, Jean; Mohlberg, Hartmut; Amunts, Katrin; Zilles, Karl; Fischl, Bruce; Hinds, Oliver; Yeo, B. T. Thomas (Oxford University Press (OUP), 2007-12)
    The human cerebral cortex is made up of a mosaic of structural areas, frequently referred to as Brodmann areas (BAs). Despite the widespread use of cortical folding patterns to perform ad hoc estimations of the locations ...
  • Rockland, Kathleen; DeFelipe, Javier (Frontiers Research Foundation, 2012-05)
    In the cerebellum and basal ganglia, projection neurons are GABAergic; but in the cerebral cortex, there has been a historically strong dichotomy between glutamatergic projection neurons and GABAergic local circuit neurons. ...
  • Siegel, Markus; Engel, Andreas K.; Donner, Tobias H. (Frontiers Media S.A., 2011-02)
    Goal-directed behavior requires the flexible transformation of sensory evidence about our environment into motor actions. Studies of perceptual decision-making have shown that this transformation is distributed across ...

Diana; Sperling, Reisa A.; Atri, Alireza; Growdon, John H.; Hyman, Bradley T.; Morris, John C.; Fischl, Bruce; Buckner, Randy L. (Oxford University Press, 2008-07)
    Alzheimer's disease (AD) is associated with neurodegeneration in vulnerable limbic and heteromodal regions of the cerebral cortex, detectable in vivo using magnetic resonance imaging. It is not clear whether abnormalities ...
  • Rockland, Kathleen; DeFelipe, Javier (Frontiers Research Foundation, 2012-01)
    The tracts within the subcortical white matter and corpus callosum provide an anatomical connectivity that is essential for normal cognitive functioning. These structures are predominantly made up of axons that are myelinated ...
