  • Identifying quantum topological phases through statistical correlation 

    Wang, H.; Bauer, B.; Troyer, M.; Scarola, V. W. (American Physical Society, 2011-03-14)

  • image transfer via color-coded projections 

    Indebetouw, G. (Optical Society of America, 1983-07)
    A technique is proposed whereby a 2-D distribution is transmitted via a set of 1-D projections. The color-coded projections are produced by illuminating the object with the dispersed spectrum of a white light source. They ...

  • Imprinting: Theater of the Absurd or ? 

    Cairns, John (Virginia Tech, 2014-01-22)

    The MiniBooNE experiment at Fermilab reports results from an analysis of (nu)overbar(e) appearance data from 11.27 X 10(20) protons on target in the antineutrino mode, an increase of approximately a factor of 2 over the ...
  • Improving Emotion Regulation with CBT in Young Children with High Functioning Autism Spectrum Disorders: A Pilot Study 

    Scarpa, A.; Reyes, N. M. (Cambridge University Press, 2011-07)
    Background and Aims: This pilot study tested the efficacy of a developmentally modified CBT for young children with Autism Spectrum Disorders (ASD) to teach emotion regulation strategies for reducing anger and anxiety, ...
  • In situ structural and texture analyses of monoclinic phase for polycrystalline Ni-rich T49.86Ni50.14 alloy from neutron diffraction data 

    Sitepu, H. (Cambridge University Press, 2008-03)
    Phase transformation temperatures of a polycrystalline Ni-rich Ti49.86Ni50.14 shape memory alloy were investigated using a differential scanning calorimeter. In situ structural and texture analyses of the monoclinic ...
  • incoherent bandpass spatial-filtering with longitudinal periodicity 

    Poon, T. C.; Indebetouw, G. (Optical Society of America, 1990-09)
    We explore the possibility of realizing bandpass filtering with longitudinal periodicity in incoherent systems. The necessary condition for spatial filtering to be longitudinally periodic is derived. Results indicate that ...

  • Incorporating Environmental Variability from Rapid Climate Change into Ecotoxicology Tests 

    Cairns, John (Society of Environmental Toxicology and Chemistry, 2014-01-22)
    As climate, similar to most complex, multivariate systems, approaches disequilibrium, variability of critical attributes increases significantly. In order for ecotoxicological testing to be reliable, it should incorporate ...
