We use the statistics of strong gravitational lensing from the JVAS/CLASS survey to impose constraints on the velocity dispersion and density profile of elliptical galaxies. This approach differs from much recent work, where the luminosity function, velocity dispersion and density profile were typically assumed in order to constrain cosmological parameters. It is indeed remarkable that observat...

AIM The aim of this research was to examine the correlation between lipid profile and bone density in postmenopausal and premenopausal women. MATERIAL AND METHODS This research covered 53 subjects who were in postmenopause and 30 subjects who had regular menstruation, older than 45. RESULTS AND DISCUSSION The postmenopausal subjects have lower bone density of the lumbar spine, if triglyceri...

In a recent paper, Lee and Neuhoff found an asymptotic formula for the distribution of the length of the errors produced by a vector quantizer with many quantization points. This distribution depends on the source probability density, the quantizer point density and the quantizer shape profile. (The latter characterizes the shapes of the quantization cells as a function of position.) The purpos...

We use the public release of ≃ 100, 000 galaxies of the Two Degree Field Galaxy Redshift Survey (2dFGRS) to analyze the internal dynamics of galaxy clusters. We select 43 non-interacting clusters which are adequately sampled in the 2dFGRS public release. Members of these clusters are selected out to ∼ 2 virial radii. We build an ensemble cluster by stacking together the 43 clusters, after appro...

AIMS The major aim of this study is to examine the role of alterations in lipid profile in women developing breast cancer. This study was carried out between May 2009 and December 2010. BACKGROUND The relationship between lipids and breast cancer is undistinguished. Until now, conflicting results have been reported on the association between lipids and risk of breast cancer development in wom...

We investigate the influence of the inner profile of lens objects on gravitational lens statistics taking into account of the effect of magnification bias and both the evolution and the scatter of halo profiles. We take the dark halos as the lens objects and consider the following three models for the density profile of dark halos; SIS (singular isothermal sphere), the NFW (Navarro Frenk White)...

Renormalized field theory and particle density profile in driven diffusive systems with open boundaries Abstract We investigate the density profile in a driven diffusive system caused by a plane particle source perpendicular to the driving force. Focussing on the case of critical bulk density ¯ c we use a field theoretic renormalization group approach to calculate the density c(z) as a function...
