Theoretical prediction of spectral and optical properties of bacteriochlorophylls in thermally disordered LH2 antenna complexes
(American Institute of Physics, 2006)
mechanical modeling, is demonstrated by calculating the absorption and circular dichroism spectra of the B800-B850 bacteriochlorophylls of the LH2 antenna complex from Rs. molischianum at room temperature. The calculated spectra are found to be in good...
Truth, Meaning, and Circularity
(Springer Verlag, 2008)
hold that the combination has a circular account of the order in which one comes to know the meaning of a sentence and comes to know its truth condition. I show that these arguments fail to identify any circularity. Arguments of the second strain hold...
Investigation of the presence of charge order in magnetite by measurement of the spin wave spectrum
(American Physical Society, 2006)
Inelastic neutron scattering results on magnetite (Fe3O4) show a large splitting in the acoustic spin wave branch, producing a 7 meV gap midway to the Brillouin zone boundary at q=(0,0,1∕2) and ℏω=43 meV. The splitting occurs below the Verwey...
Subdiffusion and lateral diffusion coefficient of lipid atoms and molecules in phospholipid bilayers
(American Physical Society, 2009)
We use a long, all-atom molecular-dynamics MD simulation combined with theoretical modeling to investigate the dynamics of selected lipid atoms and lipid molecules in a hydrated diyristoyl-phosphatidylcholine
lipid ...
Sustained resonance: a binary system perturbed by gravitational radiation
(American Institute of Physics, 2000)
damping as well as an external tidal perturbation. For further simplification, we assume that the external tidal perturbation is caused by a normally incident circularly polarized monochromatic gravitational wave. In this case, the second-order partially...
Supercell studies of the Fermi surface changes in the electron-doped superconductor LaFeAsO1‑xFx
(American Physical Society, 2008)
We study the changes in the Fermi surface with electron doping in the LaFeAsO1‑xFx superconductors with density-functional supercell calculations using the linearized augmented plane-wave method. The supercell calculations ...
Chaos in the Hill system
(arXiv, 1999)
We define the general Hill system and briefly analyze its dynamical behavior. A particular Hill system representing the interaction of a Keplerian binary system with a normally incident circularly polarized gravitational wave is discussed in detail...
A catalog of Nearby Poor Clusters of Galaxies
(American Astronomical Society, 1999)
A catalog of 732 optically selected, nearby poor clusters of galaxies covering the entire sky north of [3¡ declination is presented. The poor clusters, called WBL clusters, were identified as concentrations of
three or more galaxies...
VLT / Infrared Integral Field Spectrometer Observations of Molecular Hydrogen Lines in the Knots in the Planetary Nebula NGC 7293 (the Helix Nebula)
(2008)
Large Telescope at high spatial resolution (50-125 mas). With spatially resolved 2 micron spectra, we find that the H2 rotational temperature within the cometary knots is uniform. The rotational-vibrational temperature of the cometary knot (situated...
Chaos in the Kepler system
(American Institute of Physics, 1999)
The long-term dynamical evolution of a Keplerian binary orbit due to the emission and absorption of gravitational radiation is investigated. This work extends our previous results on transient chaos in the planar case to ...
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 ...
On the ionization of a Keplerian binary system by periodic gravitational radiation
(American Institute of Physics, 1996)
The gravitational ionization of a Keplerian binary system via normally incident periodic gravitational radiation of definite helicity is discussed. The periodic orbits of the planar tidal equation are investigated on the ...
The Gazelle Mosaic : An Inhabited Scroll in Missouri
(University of Missouri--Columbia. Museum of Art and Archaeology, 1997)
-in-trade of Roman and Early Byzantine mosaic art. On display at the Museum of Art and Archaeology is a circular mosaic fragment representing a gazelle kneeling in the middle of an acanthus scroll, which is a particularly interesting example of this type...
A Study of Relationships Between the Problems of Elementary Trumpet Students and the Mouthpieces They are Using
(1960)
The purpose or this study is to determine whether there are
relationships between the problems of elementary trumpet students
and the mouthpieces used.
The problems to be studied are problems of tone, range,
flexibility, ...
Experimental evaluation of apparent tissue surface tension based on the exact solution of the Laplace equation
(IOP, 2008)
The notion of apparent tissue surface tension offered a systematic way to interpret
certain morphogenetic processes in early development. It also allowed deducing quantitative information on cellular and molecular parameters ...
Post-Newtonian Reference Frames for Advanced Theory of the Lunar Motion and a New Generation of Lunar Laser Ranging
(arXiv, 2009)
We construct a set of post-Newtonian reference frames for a comprehensive study of the orbital dynamics and rotational motion of Moon and Earth by means of lunar laser ranging (LLR) with the precision of one millimeter. ...
Imaging 2D Optical Diffuse Reflectance in Skeletal Muscle
(The Optical Society of America, 2007-04)
We discovered a unique pattern of optical reflectance from fresh prerigor skeletal muscles, which can not be described using existing theories. A numerical fitting function was developed to quantify the equiintensity ...
The Hypothesis of Locality and its Limitations
(arXiv, 2003)
The hypothesis of locality, its origin and consequences are discussed. This supposition is necessary for establishing the local spacetime frame of accelerated observers; in this connection, the measurement of length in a ...
The Syro-Palestinian Glass Industry in the Later Hellenistic Period
(University of Missouri--Columbia. Museum of Art and Archaeology, 1979)
on local tradition, reflects the area's close identification with glassmaking. Strabo's account, written at the close of the first century B.C., or ca. A.D. 17/19 at the latest, is occasioned by his description of Ptolemais, modern Akko. Pliny emphasizes...
Gamma oscillations in the basolateral amygdala : biophysical mechanisms and computational consequences
(Society for Neuroscience, 2019)
The basolateral nucleus of the amygdala (BL) is thought to support numerous emotional behaviors through specific microcircuits. These are often thought to be comprised of feedforward networks of principal cells (PNs) and ...
