Reference frames, gauge transformations and gravitomagnetism in the post-Newtonian theory of the lunar motion
(Proceedings of the International Astronomical Union, 2010)
We construct a set of reference frames for description of the orbital and rotational motion of the Moon. We use a scalar-tensor theory of gravity depending on two parameters of the parametrized post- Newtonian (PPN) formalism ...
Beyond the standard IAU framework
(Cambridge university Press, 2010)
We discuss three conceivable scenarios of extension and/or modification of the IAU relativistic resolutions on time scales and spatial coordinates beyond the Standard IAU Framework. These scenarios include: (1) the formalism ...
Units of relativistic time scales and associated quantities
(arXiv, 2010)
This note suggests nomenclature for dealing with the units of various astronomical quantities that are used with the relativistic time scales TT, TDB, TCB and TCG. It is suggested to avoid wordings like "TDB units" and "TT ...
An electric charge has no screw sense—a comment on the twistfree formulation of electrodynamics by da Rocha & Rodrigues
(Wiley-Blackwell, 2010)
Da Rocha and Rodigues (RR) claim (i) that in classical electrodynamics in vector calculus the distinction between polar and axial vectors and in exterior calculus between twisted and untwisted forms is inappropriate and ...
Spin gaps and spin-flip energies in density-functional theory
(American Physical Society, 2010)
Energy gaps are crucial aspects of the electronic structure of finite and extended systems. Whereas much is known about how to define and calculate charge gaps in density-functional theory (DFT), and about the relation ...
The Price paid for building anew
(Rhetoric and Composition Program, University of Missouri--Columbia, 2010)
Currently, the University of Missouri-Columbia has seven construction projects being worked on throughout campus according to the campus facilities department. With the increasingly important goal of providing a top-notch ...
Magnetic excitations in the spinel compound Lix[Mn1.96Li0.04]O4 (x=0.2,0.6,0.8,1.0): How a classical system can mimic quantum critical scaling
(American Physical Society, 2010)
We present neutron-scattering results on the magnetic excitations in the spinel compounds Lix Mn1.96Li0.04 O4 x=0.2, 0.6, 0.8, 1.0 . We show that the dominant excitations below T 70 K are determined by Mn ions located in ...
Necessity of Acceleration-Induced Nonlocality
(arXiv, 2010)
The purpose of this paper is to explain clearly why nonlocality must be an essential part of the theory of relativity. In the standard local version of this theory, Lorentz invariance is extended to accelerated observers ...
HVAC optimization study
(Rhetoric and Composition Program, University of Missouri--Columbia, 2010)
Heating, ventilation, and air conditioning (HVAC) can be a very costly effort when applied in industry. So was thought to be the case at the DRS Technologies facility in West Plains, Missouri. Therefore, the Pollution ...
Gravitomagnetic Jets
(arXiv, 2010)
We present a family of dynamic rotating cylindrically symmetric Ricci-flat gravitational fields whose geodesic motions have the structure of gravitomagnetic jets. These correspond to helical motions of free test particles ...
On the de la Garza Phenomenon
(Institute of Mathematical Statistics, 2010)
Deriving optimal designs for nonlinear models is, in general, challenging. One crucial step is to determine the number of support points needed. Current tools handle this on a case-by-case basis. Each combination of ...
Cellular aggregates under pressure
(American Physical Society, 2010)
Researchers develop a new approach to measuring the viscoelastic properties of multicellular aggregates by using a micropipette aspiration technique.
Analytic measures and Bochner measurability
(2011)
Many authors have made great strides in extending the celebrated F. and M. Riesz
Theorem to various abstract settings. Most notably, we have, in chronological order,
the work of Bochner, Helson and Lowdenslager, de Leeuw ...
Coregulation of Ion Channel Conductances Preserves Output in a Computational Model of a Crustacean Cardiac Motor Neuron
(Society for Neuroscience, 2010)
Similar activity patterns at both neuron and network levels can arise from different combinations of membrane and synaptic conductance values. A strategy by which neurons may preserve their electrical output is via cell ...
Dust/gas correlations from Herschel observations
(EDP Sciences, 2010)
Context: Previous Spitzer and IRAS observations of the LMC suggest an excess of FIR emission with respect to the gas surface density traced by 12CO rotational emission lines and H i 21 cm emission. This so-called “FIR ...
Hyperactivity and Hyperagreement in Bantu
(2011)
Many Bantu languages exhibit A-movements and patterns of iterating agreement that are disallowed in Indo-European languages. In Minimalist theory, both agreement and movement are constrained by an Activity requirement ...
The SAGE-Spec Spitzer Legacy Program: The Life Cycle of Dust and Gas in the Large Magellanic Cloud
(arXiv, 2010)
The SAGE-Spec Spitzer Legacy program is a spectroscopic follow-up to the SAGE-LMC photometric survey of the Large Magellanic Cloud carried out with the Spitzer Space Telescope. We present an overview of SAGE-Spec and some ...
The Mass-loss Return from Evolved Stars to the Large Magellanic Cloud. II. Dust Properties for Oxygen-rich Asymptotic Giant Branch Stars
(American Astronomical Society, 2010)
We model multi-wavelength broadband UBVIJHKs and Spitzer IRAC and MIPS photometry and Infrared Spectrograph spectra from the SAGE and SAGE-Spectroscopy observing programs of two oxygen-rich asymptotic giant branch (O-rich ...
Gastrointestinal disease and diet
(Rhetoric and Composition Program, University of Missouri--Columbia, 2010)
Despite the large number of people affected by digestive diseases, gastroenterologists maintain a less than optimal course of treatment. The medical community has largely ignored the role that diet plays in treating and ...
Facebook : our social tool
(Rhetoric and Composition Program, University of Missouri--Columbia, 2010)
This article discusses what Facebook is and the variety of reasons people use this social networking website.
