Lagrangian and energy forms for retrieving the impulse response of the Earth due to random electromagnetic forcing
(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 ...
Elements, Spring 2011

This is the alumni magazine of the Department of Chemistry at Virginia Tech.
Heat conductivity of the DNA double helix
(American Physical Society, 2011-06-20)
Thermal conductivity of isolated single molecule DNA fragments is of importance for nanotechnology, but has not yet been measured experimentally. Theoretical estimates based on simplified (1D) models predict anomalously ...
Glass transition seen through asymptotic expansions
(Siam Publications, 2011)
Soft glassy materials exhibit the so-called glassy transition, which means that the behavior of the model at a low shear rate changes when a certain parameter (which we call the glass parameter) crosses a critical value. ...
Land and Racial Wealth Inequality
(American Economic Association, 2011)
...Explanations for the persistent and large racial wealth gap largely fall into two categories. First, racially discriminatory policies in credit markets, labor markets, school finance, and other institutions may have ...
Fundamental Physics at the Intensity Frontier
The Proceedings of the 2011 workshop on Fundamental Physics at the Intensity Frontier. Science opportunities at the intensity frontier are identified and described in the areas of heavy quarks, charged leptons, neutrinos, ...
Multiwavelength campaign on Mrk 509 III. The 600 ks RGS spectrum: unravelling the inner region of an AGN
(EDP Sciences, 2011-10)
We present the results of our 600 ks RGS observation as part of the multiwavelength campaign on Mrk 509. The very high quality of the spectrum allows us to investigate the ionized outflow with an unprecedented accuracy due ...
Ultraviolet and X-ray Variability of the Seyfert 1.5 Galaxy Markarian 817
(IOP PUBLISHING LTD, 2011-02)
We present an investigation of the ultraviolet and X-ray spectra of the Seyfert 1.5 galaxy Markarian 817. The ultraviolet analysis includes two recent observations taken with the Cosmic Origins Spectrograph (COS) in 2009 ...
Stochastic population oscillations in spatial predator-prey models
(Iop Publishing Ltd, 2011-01-01)
a precision test for an extra spatial dimension using black-hole-pulsar binaries
(IOP Publishing Ltd., 2011-08)
We discuss the observable effects of enhanced black hole mass loss in a black hole-neutron star (BH-NS) binary, due to the presence of a warped extra spatial dimension of curvature radius L in the braneworld scenario. For ...
