Cosmological parameters from SDSS and WMAP

open access: yes, 2004
We measure cosmological parameters using the three-dimensional power spectrum P(k) from over 200,000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with WMAP and other data.

Improved stellar parameters of CoRoT-7

open access: yes, 2010
Accurate parameters of the host stars of exoplanets are important for the interpretation of the new planet systems that continue to emerge. The CoRoT satellite recently discovered a transiting rocky planet with a density similar to the inner planets in ...

Soil parameters affecting longleaf pine (Pinus palustris) site quality in east Texas

open access: yesForestry Research
The decline since European colonization in longleaf pine (Pinus palustris Mill.) within its range in the southeastern United States, attributed to factors including both site conversion and fire exclusion has spurred interest in the re-establishment of ...

Disguising the Oblique Parameters

open access: yes, 2006
We point out a set of operator identities that relate the operators corresponding to the oblique corrections to operators that modify fermion couplings to the gauge bosons as well as operators that modify triple gauge boson couplings. Such identities are

Stochastic Generator of a New Family of Lifetime Distributions with Illustration

open access: yesRevstat Statistical Journal
In this article, a new family of lifetime distributions is introduced to help researchers model different types of data sets. Furthermore, the maximum likelihood method was used in estimating the model's parameters.

Fundamental parameters of QCD [PDF]

open access: yes, 2002
The theory of strong interactions, QCD, is described in terms of a few parameters, namely the strong coupling constant alpha_s and the quark masses. We show how these parameters can be determined reliably using computer simulations of QCD on a space-time
