Dust driven mass loss from carbon stars as function of stellar parameters - II. Effects of grain size on wind properties
AGB and post-AGB – Stars: atmospheres – Stars: carbon – Stars: circumstellar matter – Stars: evolution – Stars: mass loss –2 Hydrodynamics – Radiative transfer
2011/9/30
In this paper we explore grain size effects on wind properties of carbon stars, using a generalized description of radiative cross sections valid for particles of arbitrary sizes. The purpose of the s...
Plasma damping effects on the radiative energy loss of relativistic particles
Landau-Pomeranchuk-Migdal effect Ter-Mikaelian effect radiative energy loss
2011/7/21
The energy loss of a relativistic charge undergoing multiple scatterings while traversing an infinite, polarizable and absorptive plasma is investigated.
Sensitivity of Azimuthal Jet Tomography to Early Time Energy-Loss at RHIC and LHC
RHIC and LHC Energy-Loss Tomography
2011/7/20
We compute the jet path-length dependence of energy-loss for higher azimuthal harmonics of jet-fragments in a generalized model of energy-loss that can interpolate between pQCD and AdS/CFT limits and ...
We estimate the energy loss of a fast gluon propagating in a gluonic fluid due to the radiative process: gg -> ggg by relaxing some of the approximations used in previous works.
Immunity of information encoded in decoherence-free subspaces to particle loss
information decoherence-free subspaces particle loss
2011/8/17
Abstract: We demonstrate that for an ensemble of qudits, subjected to collective decoherence in the form of perfectly correlated random SU(d) unitaries, quantum superpositions stored in the decoherenc...
Mass Loss, Destruction and Detection of Sun-grazing and -impacting Cometary Nuclei
comet sun impact sun-grazing radiation collisions
2011/9/30
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...
Electron loss of fast heavy projectiles in collision with neutral targets
Electron loss neutral targets
2011/9/5
The multiple electron loss of heavy projectiles in fast ion-atom collisions has been studied in the framework of the sudden perturbation approximation. Especially, a model is developed to calculate th...
Surface plasmon modes of a single silver nanorod: an electron energy loss study
plasmon modes silver nanorod an electron energy loss study
2011/9/5
We present an electron energy loss study using energy filtered TEM of spatially resolved surface plasmon excitations on a silver nanorod of aspect ratio 14.2 resting on a 30 nm thick silicon nitride m...
Unconventional modes in lasers with spatially varying gain and loss
lasers spatially varying gain and loss
2011/9/2
We discuss a class of lasing modes created by a spatially inhomogeneous gain pro le. These lasing modes are \extra modes", in addition to, and very di erent from, conventional lasing modes,which arise...
Some Results on the Information Loss in Dynamical Systems
Dynamical Systems Information Loss Results
2011/7/7
In this work we investigate the information loss in (nonlinear) dynamical input-output systems and provide some general results. In particular, we present an upper bound on the information loss rate, ...
A Characterization of Entropy in Terms of Information Loss
Shannon entropy Tsallis entropy information theory measure-preserving function
2011/7/27
Abstract: There are numerous characterizations of Shannon entropy and Tsallis entropy as measures of information obeying certain properties. Using work by Faddeev and Furuichi, we derive a very simple...
M/M/1 retrial queueing system with loss and feedback under non-pre-emptive priority service by matrix geometric method
Single Server Stochastic nature Low priority
2010/9/26
Consider a single server retrial queueing system with loss and feedback under Non-pre-emptive priority service in which two types of customers arrive in a Poisson process with arrival rate λ1 for low ...
After recovering from a cold or other infection, your body’s immune system is primed to react quickly if the same agent tries to infect you. White blood cells called memory T cells specifically rememb...

2010/12/20
During the FROST-2 (FReezing Of duST) measurement campaign conducted at the Leipzig Aerosol Cloud Interaction Simulator (LACIS), we investigated changes in the ice nucleation properties of 300 nm Ariz...
The use of remote sensing to quantify wetland loss in the Choke Mountain range, Upper Blue Nile basin, Ethiopia
remote sensing quantify wetland the Choke Mountain range
2010/12/22
Wetlands provide multiple ecosystem services such as storing and regulating water flows and water quality, providing unique habitats to flora and fauna, and regulating micro-climatic conditions. Conve...
