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

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

#### 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...#### Developing molecular docking methods to model protein interactions

(University of Missouri--Columbia, 2016)

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In many cellular processes, proteins carry out their functions through interacting with other molecules, such as small compounds (i.e. ligands), peptides ...

#### 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 ...

#### 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 ...

#### Theoretical and computational modeling of the dynamics of multicellular and lipid membrane systems

(University of Missouri--Columbia, 2016)

This dissertation presents two research projects that apply theoretical and computational modeling to (1) describe and predict the formation and shape evolution of three-dimensional (3D) bioprinted tissue constructs, and ...

#### Measurement Theory and General Relativity

(arXiv, 2000-03)

The theory of measurement is employed to elucidate the

**physical**basis of general relativity. For measurements involving phenomena with intrinsic length or time scales, such scales must in general be negligible compared to the (translational...#### Neutron interferometry in a rotating frame of reference

(American Physical Society, 1988-12)

The

**physical**basis for the description of phenomena by a rotating observer is investigated. A simple, yet tentative, extension of the hypothesis of locality is used to determine the interference phase shift induced by the rotation of a neutron...#### Massive-Star Supernovae as Major Dust Factories

(arXiv, 2006-06)

We present late-time optical and mid-infrared observations of the Type-II supernova 2003gd in NGC 628. Mid-infrared excesses consistent with cooling dust in the ejecta are observed 499-678 days after outburst, and are ...

#### Inertial effects of an accelerating black hole

(American Institute of Physics, 2005-03)

We consider the static vacuum C metric that represents the gravitational field of a
black hole of mass m undergoing uniform translational acceleration A such that mA 1 33 . The influence of the inertial acceleration ...

#### Tidal acceleration of ultrarelativistic particles

(EDP Sciences, 2005-05)

We investigate the motion of free relativistic particles relative to the ambient medium around a gravitationally
collapsed system. If the relative speed exceeds a critical value given by c/√2, the gravitational tidal ...

#### Ultrarelativistic motion: inertial and tidal effects in Fermi coordinates

(Institute of Physics, 2004-12)

Fermi coordinates are the natural generalization of inertial Cartesian
coordinates to accelerated systems and gravitational fields. We study themotion
of ultrarelativistic particles and light rays in Fermi coordinates ...

#### 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 ...

#### 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...#### 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 ...

#### Mashhoon replies

(American Physical Society, 1992-06)

B. Mashhoon discusses comments made by J. Anandan on the results on the coupling of intrinsic spin to the angular velocity in a neutron interferometry.(AIP)

#### 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 ...

#### 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 ...
