TD-88Up: Upgraded neutral Earth's thermosphere total density TD-88 model [PDF]
Serbian Astronomical Journal, 2009 Improved constants of the total density TD-88 model for the Earth's neutral thermosphere are calculated. The model is fully functional within the height range of 200 to 500 km, with fixed values of the mean solar flux and geomagnetic index.

Earth, Planets and Space, 2021 Thermospheric mass density values around the 400-km altitude in the cusp can be significantly enhanced as compared to regions around the cusp. To gain insights into the extent to which the magnitude of the cusp mass density enhancements can be explained ...

Parametric Estimation of Risk Neutral Density Functions [PDF]
, 2011 This chapter deals with the estimation of risk neutral distributions for pricing index options resulting from the hypothesis of the risk neutral valuation principle. After justifying this hypothesis, we shall focus on parametric estimation methods for the risk neutral density functions determining the risk neutral distributions.

Estimating the mass density of neutral gas at $z < 1$ [PDF]
, 1997 We use the relationships between galactic HI mass and B-band luminosity determined by Rao & Briggs to recalculate the mass density of neutral gas at the present epoch based on more recent measures of the galaxy luminosity function than were available to ...

The Simulated HI Sky at low redshift [PDF]
, 2009 Observations of intergalactic neutral hydrogen can provide a wealth of information about structure and galaxy formation, potentially tracing accretion and feedback processes on Mpc scales. Below a column density of NHI ~ 10^19 cm-2, the "edge" or typical

Sources of the High-Latitude Thermospheric Neutral Mass Density Variations [PDF]
Journal of Astronomy and Space Sciences, 2010 We investigate the sources of the variation of the high-latitude thermospheric neutral mass density depending on the interplanetary magnetic field (IMF) conditions.

Observation of large many-body Coulomb interaction effects in a doped quantum wire
, 2002 We demonstrate strong one dimensional (1-D) many-body interaction effects in photoluminescence (PL) in a GaAs single quantum wire of unprecedented optical quality, where 1-D electron plasma densities are controlled via electrical gating.
