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...
A definition of bioeconomy through the bibliometric networks of the scientific literature
(University of Missouri, College of Agriculture, Food and Natural Resources, 2018)
The purposes of this paper are to present the different bioeconomy strategies within European Union (the national member states' published bioeconomy strategies are presented), the United States, and China, to construct ...
Gravitomagnetism and the Clock Effect
(arXiv, 1999)
clock effect. This remarkable effect, which involves the difference in the proper periods of a standard clock in prograde and retrograde circular geodesic orbits around a rotating mass, is discussed in detail. The implications of this effect...
Gravitation and Nonlocality
(arXiv, 2001)
The physical basis of the standard theory of general relativity is examined and a nonlocal theory of accelerated observers is described that involves a natural generalization of the hypothesis of locality. The nonlocal ...
Supercritical CO2 extraction of porogen phase: An alternative route to nanoporous dielectrics
(Materials Research Society, 2004)
We present a supercritical CO2 (SCCO2) process for the preparation of nanoporous organosilicate thin films for ultralow dielectric constant materials. The porous structure was generated by SCCO2 extraction of a sacrificial ...
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 ...
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 ...
Turning again in Tibullus 1.5
(2002)
in the elegy, or based interpretation of it upon: 1) the [... ] in general, or 2) a specially developed form of the [ ... ], or 3) a statement of pessimism vs. guarded optimism with a remarkable, "oracular" close, or 4) a skillfully developed interplay...
Monte Carlo simulation method for Laughlin-like states in a disk geometry
(American Physical Society, 2003)
We discuss an alternative accurate Monte Carlo method to calculate the ground-state energy and related quantities for Laughlin states of the fractional quantum Hall effect in a disk geometry. This alternative approach ...
Drude weight, plasmon dispersion, and pseudospin response in doped graphene sheets
(arXiv, 2009)
Plasmons in ordinary electron liquids are collective excitations whose long-wavelength limit is rigid center-of-mass motion with a dispersion relation that is, as a consequence of Galileian invariance, unrenormalized by ...
Acceleration-induced nonlocality: kinetic memory versus dynamic memory
(arXiv, 2001)
The characteristics of the memory of accelerated motion in Minkowski spacetime are discussed within the framework of the nonlocal theory of accelerated observers. Two types of memory are distinguished: kinetic and dynamic. ...
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 ...
Delay equations and radiation damping
(arXiv, 2001)
Starting from delay equations that model field retardation effects, we study the origin of runawaymodes that appear in the solutions of the classical equations of motion involving the radiation reaction force. When retardation ...
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. ...
The baths of Trajan Decius, or of Philip the Arab?
(2002)
In a recent publication Laetitia La Follette collected the evidence for the Baths of Trajan Decius, an important but little-known imperial monument of the mid-3rd c. in Rome. Bringing together the ancient literary and ...
Drude weight, plasmon dispersion, and a.c. conductivity in doped graphene sheets
(arXiv, 2011)
We demonstrate that the plasmon frequency and Drude weight of the electron liquid in a doped graphene sheet are strongly renormalized by electron-electron interactions even in the long-wavelength limit. This e ffect is not ...
The Calibration of Mid-Infrared Star Formation Rate Indicators
(American Astronomical Society, 2007)
populations, in addition to the ionizing ones, in agreement with previous findings. Two SFR calibrations, one using the 24 m emission and the other using a combination of the 24 m and H luminosities(Kennicutt and coworkers), are presented. No calibration...
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 ...
Magnetic tweezers for intracellular applications
(American Institute of Physics, 2003)
We have designed and constructed a versatile magnetic tweezer primarily for intracellular investigations. The micromanipulator uses only two coils to simultaneously magnetize to saturation micron-size superparamagnetic ...
