#### Center of mass and relative motion in time dependent density functional theory

(American Physical Society, 1995-04)

It is shown that the theorem asserting separability of the center of mass motion for a system of interacting particles in a harmonic external potential is satisfied in the time dependent density functional theory, provided ...

#### 3-D Dynamics of Interactions between Stellar Winds and the Interstellar Medium as Seen by AKARI and Spitzer

(2009-05)

Recent far-infrared mapping of mass-losing stars by the AKARI Infrared

**Astronomy**Satellite and Spitzer Space Telescope have suggested that far-infrared bow shock structures are probably ubiquitous around these masslosing stars, especially when...#### Rigorous upper bound for the persistent current in systems with toroidal geometry

(American Physical Society, 1995-01)

It is shown that the absolute value of the persistent current in a system with toroidal geometry is rigorously less than or equal to eħNα/4πmr02, where N is the number of electrons, r0-2= 〈ri-2〉 is the equilibrium average ...

#### An informal history of **astronomy** at the University of Missouri-Columbia

(Dept. of Physics and Astronomy, University of Missouri - Columbia,, 1981)

#### Stability of pulsar rotational and orbital periods

(arXiv, 2009-09)

Millisecond and binary pulsars are the most stable astronomical standards of frequency. They can be applied to solving a number of problems in

**astronomy**and time-keeping metrology including the search for a stochastic gravitational wave background...#### The reversibility of the adsorption of methane-methyl mercaptan mixtures in nanoporous carbon

(University of Missouri--Columbia, 2011)

Methane is the main constituent of natural gas (NG). As fuel for vehicular applications NG requires sorbents that allow efficient, reversible and safe storage at room temperature and moderate pressure. To enable easy human ...

#### Computational studies of methane adsorption in nanoporous carbon

(University of Missouri--Columbia, 2012)

In this thesis we have completed computational studies using Grand Canonical Monte Carlo on the adsorption of methane into a graphitic nanoporous adsorbent with slit-shaped pores. Simulations were done at a temperature of ...

#### Erratum: Dynamical exchange-correlation potentials for an electron liquid [Phys. Rev. B 65, 235121 (2002)]

(American Physical Society, 2005-04)

Erratum concerning Dynamical exchange-correlation potentials for an electron liquid [Phys. Rev. B 65, 235121 (2002)]

#### Anomalous layering of Fe(CO)5 adsorbed on graphite

(American Physical Society, 1989-02)

Synchrotron x-ray diffraction experiments reveal the adsorption of iron pentacarbonyl [Fe(CO)5] on graphite basal-plane surfaces to be an extreme example of incomplete wetting in which only one solid layer of film coexists ...

#### Numerical Data Processing Simulation of Microarcsecond Classical and Relativistic Effects in Space Astrometry

(arXiv, 2000-06)

The accuracy of astrometric observations conducted via a space-borne optical
interferometer orbiting the Earth is expected to approach a few microarcseconds. Data processing of such extremely high- precision measurements ...

#### On the relation between the scalar and tensor exchange-correlation kernels of the time-dependent density-functional theory

(arXiv, 2010-01)

The scalar $f_{xc}$ and tensor $\hat{f}_{xc}$ exchange-correlation (xc) kernels are key ingredients of the time-dependent density functional theory and the time-dependent current density functional theory, respectively. ...

#### Toward understanding the 3.4 micron and 9.7 micron extinction feature variations from the local diffuse interstellar medium to the Galactic center

(2008-12)

Observationally, both the 3.4 μm aliphatic hydrocarbon C-H stretching absorption feature and the 9.7 μm amorphous silicate Si-O stretching absorption feature show considerable variations from the local diffuse interstellar ...

#### Relativistic motion of spinning particles in a gravitational field

(arXiv, 2005-05)

The relative motion of a classical relativistic spinning test particle is studied with respect to a nearby free test particle in the gravitational field of a rotating source. The effects of the spincurvature coupling force ...
