Ponderomotive forces and wave dispersion: two sides of the same coin
Ponderomotive wave dispersion coin Quantum Physics
2011/8/4
Abstract: Presented here is a general view on adiabatic and resonant wave-particle interactions leading to a uniform description of nonlinear ponderomotive effects in very different environments, from...
Real-time, fast radio transient searches with GPU de-dispersion
Real-time fast radio transient searches de-dispersion
2011/10/8
The identification, and subsequent discovery, of fast radio transients through blind-search surveys requires a large amount of processing power, in worst cases scaling as $\mathcal{O}(N^3)$. For this ...
Interference Focusing for Simplified Optical Fiber Models with Dispersion
Simplified Optical Fiber Models Dispersion Information Theory
2011/9/1
Abstract: A discrete-time two-user interference channel model is developed that captures non-linear phenomena that arise in optical fiber communication employing wavelength-division multiplexing (WDM)...
Chemical abundances in the protoplanetary disk LV2 (Orion) - II: High dispersion VLT observations and microjet properties
ISM – abundances HII regions ISM:stars: pre-main-sequence protostars protoplan- etary disks
2011/9/29
Integral field spectroscopy of the LV2 proplyd is presented taken with the VLT/FLAMES Argus array at an angular resolution of 0.31x0.31 arcsec^2 and velocity resolutions down to 2 km/s per pixel. Foll...
Redshift Evolution of the Galaxy Velocity Dispersion Function
Redshift Evolution Galaxy Velocity Dispersion
2011/9/28
We present a study of the evolution of the galaxy Velocity Dispersion Function (VDF) from z=0 to z=1.5 using photometric data from the UKIDSS Ultra Deep Survey (UDS) and Newfirm Medium Band Survey (NM...
On the lack of dispersion for a class of magnetic Dirac flows
Dirac equation Strichartz estimates dispersive equations magnetic potential
2011/8/25
Abstract: We show that global Strichartz estimates for magnetic Dirac operators generally fails, if the potentials do not decay fast enough at in?nity. In order to prove this, we construct some explic...
y Dispersion Analysis for the Hayabusa Spacecraft using Ground Based Optical Observation
astrometry — celestial mechanics — Hayabusa — orbit determination — space vehicles
2011/9/8
Hayabusa asteroid explorer successfully released the sample capsule to Australia on June 13, 2010. Since the Earth reentry phase of sample return was critical, many backup plans for predicting the lan...
Wavelength tunable spectral compression in a dispersion-increasing fiber
Wavelength dispersion-increasing fiber
2011/8/26
Adiabatic soliton spectral compression in a dispersion-increasing fiber is demonstrated both numerically and experimentally.We show a positively-chirped pulse provides better spectral compression in a...

Quantum dispersion relations for excitations of long folded spinning superstring in AdS_5 x S^5
Quantum dispersion relations folded spinning superstring
2010/12/23
We use AdS_5 x S^5 superstring sigma model perturbation theory to compute the leading one-loop corrections to the dispersion relations of the excitations near a long spinning string in AdS. This inves...
A Dispersion Relation for the Density of States With Application to the Casimir Effect
Dispersion Relation the Density of States the Casimir Effect
2010/12/27
The trace of a function of a Schrodinger operator minus the same for the Laplacian can be expressed in terms of the determinant of its scattering matrix. The naive formula for this determinant is dive...

2010/11/30
The study reviews the emission estimates of sulphur oxides (SOx) and primary particulate matter (PM) from the major industrial sources of Kola Peninsula. Analysis of the disagreements between the exis...
HIFLUGCS: Galaxy Cluster Scaling Relations between X-ray Luminosity, Gas Mass, Cluster Radius, and Velocity Dispersion
Cosmology observations — (Cosmology:) dark matter — Galaxies clusters: general — Methods
2010/11/15
We present relations between X-ray luminosity and velocity dispersion (L − ), X-ray luminosity and gas mass (L − Mgas), and between cluster radius and velocity dispersion (r500 − )...
