    • Jastrow-correlated wave functions for flat-band lattices 

      Wang, H.; Scarola, V. W. (American Physical Society, 2011-06-20)
      The electronic band structure of many compounds, e.g., carbon-based structures, can exhibit essentially no dispersion. Models of electrons in flat-band lattices define nonperturbative strongly correlated problems by default. ...

      Transient and photomodulation spectroscopy is used in order to determine decay times and densities of both emitting and absorbing species in the wide band-gap semiconductor poly-2,5-diheptyl-1,4-phenylene-alt-2, S-thienylene ...
    • King Midas and the Money Touch 

      Cairns, John (Virginia Tech, 2014-01-22)
      King Midas is known in myths and legends as the king who wished that all he touched might become gold. Modern humans are just as greedy as King Midas. In their efforts to make a bigger profit, they are destroying the ...
    • Koster-Slater model for the interface-state problem 

      Di Ventra, M.; Berthod, C.; Binggeli, N. (American Physical Society, 2000-10)
      A Koster-Slater approach to the problem of localized states at semiconductor interfaces has been developed. It allows us to relate the existence and/or the energy position of interface states to some essential bulk features ...
    • Label-free DNA sequence detection using oligonucleotide functionalized optical fiber 

      Wang, X. W.; Cooper, K. L.; Wang, A. B.; Xu, J. C.; Wang, Z. A.; Zhang, Y.; Tu, Z. J. (AIP Publishing, 2006-10)
      The authors present a label-free method for direct detection of deoxyribonucleic acid (DNA) sequences. The capture DNA is immobilized onto the surface of a silica optical fiber tip by means of the layer-by-layer electrostatic ...
    • Lagrangian and energy forms for retrieving the impulse response of the Earth due to random electromagnetic forcing 

      Slob, E.; Weiss, C. J. (American Physical Society, 2011-08-10)
      We distinguish between trivial and nontrivial differences in retrieving the real or imaginary parts of the Green's function. Trivial differences come from different Green's function definitions. The energy and Lagrangian ...
    • landscape patterns and dispersal success: simulated population dynamics in the brown treecreeper 

      Cooper, C. B.; Walters, J. R.; Priddy, J. (Ecological Society of America, 2002-12)
      We used a spatially explicit, individual-based simulation model to explain the possible role of patch isolation in causing observed declines of Brown Treecreepers (Climacteris picumnits) in northern New South Wales, ...
    • large eddy simulation of turbulent channel flows by the rational large eddy simulation model 

      Iliescu, T.; Fischer, P. F. (AIP Publishing, 2003-10)
      The rational large eddy simulation (RLES) model is applied to turbulent channel flows. This approximate deconvolution model is based on a rational (subdiagonal Pade) approximation of the Fourier transform of the Gaussian ...
    • Layer-by-layer self-assembled conductor network composites in ionic polymer metal composite actuators with high strain response 

      Liu, S.; Montazami, R.; Liu, Y.; Jain, V.; Lin, M. R.; Heflin, J. R.; Zhang, Q. M. (AIP Publishing, 2009-07)
      We investigate the electromechanical response of conductor network composite (CNC) fabricated by the layer-by-layer (LbL) self-assembly method. The process makes it possible for CNCs to be fabricated at submicron thickness ...
    • Least-squares finite element approximations to solutions of interface problems 

      Cao, Y. Z.; Gunzburger, M. D. (Siam Publications, 1998-02)
      A least-squares finite element method for second-order elliptic boundary value problems having interfaces due to discontinuous media properties is proposed and analyzed. Both Dirichlet and Neumann boundary data are treated. ...
    • Leptonic CP violation search and the ambiguity of delta m(31)(2) 

      Koike, M.; Okamura, N.; Saito, M.; Takeuchi, T. (American Physical Society, 2006-03)
      We consider a search for the CP-violating angle delta(CP) in long baseline neutrino oscillation experiments. We show that the subleading delta(CP)-dependent terms in the nu(mu)->nu(e) oscillation probability can be easily ...
    • Lets Talk About the Elephant in the Living Room 

      Cairns, John (EcoRes Forum, 2014-01-22)
      Overpopulation is the _elephant in the living room _ the issue everyone sees but no one will address. Exponential population growth on a finite planet is neither sustainable nor desirable; however, politicians refuse to ...
    • Life Boat Ethics Revisited: What Should Be the Reaction to the Maldives Crisis 

      Cairns, John (Asian Journal of Experimental Sciences, 2014-01-22)
