A Measure of Media Bias
(Department of Economics, 2005)
In this paper we estimate ADA (Americans for Democratic Action) scores for major media outlets such as the New York Times, USA Today, Fox News' Special Report, and all three network television news shows. Our estimates ...
Effects of Timber Harvest on Amphibian Populations: Understanding Mechanisms from Forest Experiments. Appendix
(2009)
The Appendix provides a summary of results for four forest management treatments according to region, species, and response variables.
A Storyteller's Story: Gladys A. Coggswell
(MU Museum of Art and Archaeology, 2005)
Mrs. Gladys A. Coggswell, a master traditional artist in African-American storytelling from Frankford, MO., will be the recipient of the 2005 Missouri Arts Award in the Individual Artist category. This prestigious award ...
Numerical Methods for the Simulation of Dynamical Mass Transfer in Binaries
(American Astronomical Society, 2002)
We describe computational tools that have been developed to simulate dynamical mass transfer in semidetached, polytropic binaries that are initially executing synchronous rotation upon circular orbits.
Initial equilibrium ...
Some upper bounds on the number of resonances for manifolds with infinite cylindrical ends
(2002)
We prove some sharp upper bounds on the number of resonances associated with the Laplacian, or Laplacian plus potential, on a manifold with infinite cylidrical ends.
Annealing-Dependent Magnetic Depth Profile in Ga[1-x]Mn[x]As
(American Physical Society, 2004)
We have studied the depth-dependent magnetic and structural properties of as-grown and optimally annealed Ga[1-x]Mn[x]As films using polarized neutron reflectometry. In addition to increasing total magnetization, the ...
Multiwavelength Study of Pulsation and Dust Production in Mira Variables Using Optical Interferometry for Constraints
(American Institute of Physics, 2009)
Optical interferometry is a technique by which the diameters and indeed the direct pulsations of stars are routinely being measured. As a follow-on to a 7 year interferometric campaign to measure the pulsations of over 100 ...
Astrodynamical Space Test of Relativity using Optical Devices I (ASTROD I) - A class-M fundamental physics mission proposal for Cosmic Vision 2015-2025
(arXiv, 2008)
ASTROD I is a planned interplanetary space mission with multiple goals. The primary aims are: to test General Relativity with an improvement in sensitivity of over 3 orders of magnitude, improving our understanding of ...
Post-Newtonian limitations on measurement of the PPN parameters caused by motion of gravitating bodies
(Wiley, 2009)
We derive an explicit Lorentz-invariant solution of the Einstein and null geodesic equations for data processing of the time delay and ranging experiments in the gravitational field of moving gravitating bodies of the Solar ...
The role of triplet states in the emission mechanism of polymer light-emitting diodes
(arXiv, 2009)
The blue emission of polyfluorene (PF) based light-emitting diodes (LEDs) is known to degrade due to a low energy green emission, which hitherto has been attributed to oxidative defects. By studying the electroluminescence ...
Recent VLBA/VERA/IVS Tests of General Relativity
(arXiv, 2009)
We report on recent VLBA/VERA/IVS observational tests of General Relativity. First, we will summarize the results from the 2005 VLBA experiment that determined gamma with an accuracy of 0.0003 by measuring the deflection ...
Radio Interferometric Tests of General Relativity
(arXiv, 2009)
Since VLBI techniques give microarcsecond position accuracy of celestial objects, tests of GR using radio sources as probes of a gravitational field have been made. We present the results from two recent tests using the ...
Tuning intermolecular interactions in di-octyl substituted polyfluorene via hydrostatic pressure
(arXiv, 2009)
Polyfluorenes (PFs) represent a unique class of poly para-phenylene based blue-emitting polymers with intriguing structure-property relationships. Slight variations in the choice of functionalizing side chains result in ...
Progress in Measurements of the Gravitational Bending of Radio Waves Using the VLBA
(American Astronomical Society, 2009)
We have used the Very Long Baseline Array (VLBA) at 43, 23, and 15 GHz to measure the solar gravitational deflection of radio waves among four radio sources during an 18 day period in 2005 October. Using phase- referenced ...
The role of triplet excitons in enhancing polymer solar cell efficiency: a photo-induced absorption study
(arXiv, 2009)
Inclusion of heavy metal atoms in a polymer backbone allows transitions between the singlet and triplet manifolds. Interfacial dissociation of triplet excitons constitutes a viable mechanism for enhancing photovoltaic (PV) ...
Millimeter Laser Ranging to the Moon: a comprehensive theoretical model for advanced data analysis
(arXiv, 2009)
Lunar Laser Ranging (LLR) measurements are crucial for advanced exploration of the evolutionary history of the lunar orbit, the laws of fundamental gravitational physics, selenophysics and geophysics as well as for future ...
Polyfluorene as a model system for space-charge-limited conduction
(arXiv, 2008)
Ethyl-hexyl substituted polyfluorene (PF) with its high level of molecular disorder can be described very well by one-carrier space-charge-limited conduction for a discrete set of trap levels with energy $\sim$ 0.5 eV above ...
On the two approaches to the data analysis of the Cassini interplanetary relativity experiment
(Elsevier, 2009)
We compare two theoretical approaches to the data analysis of the Cassini relativity experiment based on the Doppler tracking and the time delay technique that were published correspondingly by Kopeikin et al. [S.M. Kopeikin, ...
Stability of pulsar rotational and orbital periods
