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 ...
Correcting Optical-Axis Calculation in Polarization-Sensitive Optical Coherence Tomography
(IEEE Transactions on Biomedical Engineering, 2010-10)
Polarization-sensitive optical coherence tomography (PSOCT) has found many applications in imaging birefringence tissue samples. Polarization-sensitive detection is often implemented by utilizing a circularly polarized incident light and detecting...
A Firework of H2 Knots in the planetary nebula NGC 7293 (The Helix Nebula)
(American Astronomical Society, 2009)
We present a deep and wide field-of-view (4 × 7 ) image of the planetary nebula (PN) NGC 7293 (the Helix Nebula) in the 2.12 μm H2 v = 1 → 0 S(1) line. The excellent seeing (0. 4) at the Subaru Telescope, allows
the details of cometary knots...
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 ...
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 ...
The Multitude of Molecular Hydrogen Knots in the Helix Nebula
(Institute of Physics, 2005)
. The brightest H2 emission (~3 × 10-4 ergs s-1 cm-2 sr-1) may be enhanced by a larger than unity area filling factor of H2 knots or may be an individual H2 knot exposed to direct starlight, causing rapid photoevaporation compared with the more embedded knots...
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...
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 ...
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...
Assessment of the Impact of the Planetary Scale on the Decay of Blocking and the Use of Phase Diagrams and Enstrophy as a Diagnostic
(Pleiades Publishing, 2007-01)
It was shown that abrupt changes in the large-scale structure of atmospheric flows may lead to the rapid decay of blocking. Analysis of phase diagrams made it possible to identify when sharp changes occurred in the dynamics ...
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 ...

Vocal and Choral Techniques in England: 1980-1910
(1981)
The main task of this paper will lie in the summation of various vocal techniques, followed by a summation of various choral techniques. It will be argued that voice teachers significantly influenced choral conductors. ...

Influence of Quantum Size Effects on Island Coarsening
(American Physical Society, 2006)
Surface x-ray scattering and scanning-tunneling microscopy experiments reveal novel coarsening behavior of Pb nanocrystals grown on Si 111 - 7 7 . It is found that quantum size effects lead to the
breakdown of the ...
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
(arXiv, 2005)
The extremely high precision of current radio/optical interferometric observations and the unparalleled sensitivity of existing (LIGO) and future (LISA, ASTROD) gravitational-wave detectors demand a much better theoretical ...
Spin, acceleration and gravity
(American Institute of Physics, 2004)
The massless field perturbations of the accelerating Minkowski and Schwarzschild spacetimes are studied. The results are extended to the propagation of the Proca field in Rindler spacetime. We examine critically the ...
The SAGE-Spec Spitzer Legacy program: The life-cycle of dust and gas in the Large Magellanic Cloud: Point source classification I.
(arXiv, 2010)
We present the classification of 197 point sources observed with the Infrared Spectrograph in the SAGE-Spec Legacy program on the Spitzer Space Telescope. We introduce a decision-tree method of object classification based ...
Drumming for the Divine : A Female Tympanon Player from Cyprus
(University of Missouri--Columbia. Museum of Art and Archaeology, 2002)
"Musical performance is an integral part of many cultural events. Artistic representations, as well as literary sources, provide evidence that music created a joyous atmosphere during celebrations, promoted a spiritual ...
