Abstract We present an observational analysis of the electron thermal energy budget using data from Parker Solar Probe. use macroscopic moments, obtained our fits to measured distribution function, evaluate based on second moment Boltzmann equation. separate contributions overall reversible and irreversible processes. find that source must be in inner heliosphere over heliocentric distance rang...

Context. Rapid rotation modifies the structure of the frequency spectrum of pulsating stars, thus making mode identification difficult. Aims. We look for new forms of organisation for the frequency spectrum that can provide a basis for mode identification at high rotation rates. Methods. Acoustic modes in uniformly rotating polytropic models of stars are computed using a numerical code that ful...

Although present in many copies in the mouse genome, xenotropic murine leukemia viruses cannot infect cells from laboratory mice because of the lack of a functional cell surface receptor required for virus entry. In contrast, cells from many nonmurine species, including human cells, are fully permissive. Using an expression library approach, we isolated a cDNA from HeLa cell RNA that conferred ...

A global extension theorem is established for isotropic singularities in polytropic perfect fluid Bianchi space-times. When an extension is possible, the limiting behaviour of the physical space-time near the singularity is analysed.

The post-Newtonian approximation of general relativistic Liouville’s equation is presented. Two integrals of it, generalizations of the classical energy and angular momentum, are obtained. Polytropic models are constructed as an application. Key word:relativistic systems:static structures; methods: numerical

The perturbation method is applied to numerical solution of the Lane-Emden Equation (LEE)of arbitrary index n, and the global parameters of polytropes are found as function of polytropic index n.
