Constraints on the Lifetimes of Disks Resulting from Tidally Destroyed Rocky Planetary Bodies
circumstellar matter minor planets asteroids general planetary systems abundances white dwarfs
2012/2/23
Spitzer IRAC observations of 15 metal-polluted white dwarfs reveal infrared excesses in the spectral energy distributions of HE 0110-5630, GD 61, and HE 1349-2305. All three of these stars have helium...
Stochastic treatment of finite-N effects in mean-field systems and its application to the lifetimes of coherent structures
Stochastic treatment finite-N effects mean-field systems lifetimes of coherent structures
2011/8/29
Abstract: A stochastic treatment yielding to the derivation of a general Fokker-Planck equation is presented to model the slow convergence towards equilibrium of mean-field systems due to finite-N eff...
Atmospheric lifetimes and Ozone Depletion Potentials of trans-1-chloro-3,3,3-trifluoropropylene and trans-1,2-dichloroethylene in a three-dimensional model
Atmospheric lifetimes and Ozone Depletion trans-1-chloro-3,3,3-trifluoropropylene trans-1,2-dichloroethylene a three-dimensional model
2010/11/30
The chloroalkenes trans-1-chloro-3,3,3-trifluoropropylene (tCFP) and trans-1,2-dichloroethylene (tDCE) have been proposed as candidate replacements for other compounds in current use that cause concer...

Extremely long quasiparticle spin lifetimes in superconducting aluminium using MgO tunnel spin injectors
Extremely long quasiparticle spin lifetimes superconducting aluminium
2010/11/23
There has been an intense search in recent years for long-lived spin-polarized carriers for spintronic and quantum-computing devices. Here we report that spin polarized quasi-particles in superconduct...
Species abundance distributions in neutral models with immigration or mutation and general lifetimes
Species abundance distribution Crump–Mode–Jagers process splitting tree branching process
2010/12/15
We consider a general, neutral, dynamical model of biodiversity. Individuals have i.i.d.
lifetime durations, which are not necessarily exponentially distributed, and each individual
gives birth inde...
Shirokov's contracting lifetimes and the interpretation of velocity eigenstates for unstable quantons
contracting lifetimes velocity eigenstates unstable quantons
2009/11/20
This paper is concerned with the interpretation of velocity eigenstates for unstable quantons, their relationship to space-like momentum eigenstates for such quantons and the explanation of Shirokov’s...

Photonic Crystal Nanocavities with Extremely Long Photon Lifetimes and Their Applications
Photonic crystal High-Q nanocavity Photonic DRAM
2009/6/1
Photonic crystal (PhC) nanocavities with ultrahigh Q values are reviewed. The demonstrated Q for a width-modulated PhC nanocavity is extremely high at 1.2×106, which corresponds to a photon lifetime o...
Upper Bounds for the Selection of the Cryptographic Key Lifetimes: Bounding the Risk of Key Exposure in the Presence of Faults

2009/4/2
With physical attacks threatening the security of current
cryptographic schemes, no security policy can be developed without taking
into account the physical nature of computation.

Application of the variability-size relationship to atmospheric aerosol studies: estimating aerosol lifetimes and ages
variability-size relationship atmospheric aerosol estimating aerosol lifetimes ages
2009/3/12
Aerosol variability is examined as function of particle size for data collected over the Northern Indian Ocean in February 1999 as part of the INDOEX experiment. It was found that for particles believ...
SCIAMACHY tropospheric NO2 over Switzerland: estimates of NOx lifetimes and impact of the complex Alpine topography on the retrieval
SCIAMACHY tropospheric NO2 Switzerland NOx lifetimes complex Alpine topography
2008/12/26
This study evaluates NO2 vertical tropospheric column densities (VTCs) retrieved from measurements of the Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY) above Switze...
Mortality change roils period rates. In the short term, conventional calculations of age-specific probabilities of death and life expectancy in the period immediately after the change depend on how ma...
On Spatial Scales and Lifetimes of SST Anomalies beneath a Diffusive Atmosphere
sea surface temperature Diffusive Atmosphere Spatial Scales
2008/11/11
The authors identify spatial and temporal scales in a one-dimensional linear, diffusive atmospheric energy balance model coupled everywhere to a slab mixed layer of fixed depth. Mathematically, the mo...
