An investigation of gravitational lens determinations of H_o in quintessence cosmologies [PDF]

, 2002
There is growing evidence that the majority of the energy density of the universe is not baryonic or dark matter, rather it resides in an exotic component with negative pressure.

Generalized uncertainty relations: Theory, examples, and Lorentz invariance [PDF]

, 1995
The quantum-mechanical framework in which observables are associated with Hermitian operators is too narrow to discuss measurements of such important physical quantities as elapsed time or harmonic-oscillator phase.

Confidence Intervals for Comparing the Variances of Two Independent Birnbaum-Saunders Distributions

Symmetry, 2022
Fatigue in a material occurs when it is subjected to fluctuating stress and strain, which usually results in failure due to the accumulated damage.

Cosmology with gamma-ray bursts: II Cosmography challenges and cosmological scenarios for the accelerated Universe [PDF]

, 2016
Context. Explaining the accelerated expansion of the Universe is one of the fundamental challenges in physics today. Cosmography provides information about the evolution of the universe derived from measured distances, assuming only that the space time ...

Comparison Analysis on the Coefficients of Variation of Two Independent Birnbaum-Saunders Distributions by Constructing Confidence Intervals for the Ratio of Coefficients of Variation

Sains Malaysiana, 2022
The fatigue failure of materials can be investigated by applying the Birnbaum-Saunders (BS) distribution to fatigue failure datasets. The coefficient of variation (CV) is an important descriptive statistic that is widely used to measure the dispersion of

Constraining Scale-Dependent Non-Gaussianity with Future Large-Scale Structure and the CMB [PDF]

, 2012
We forecast combined future constraints from the cosmic microwave background and large-scale structure on the models of primordial non-Gaussianity.

Confidence intervals for ratio of coefficients of variation of Inverse Gaussian distribution

ICBICC, 2022
This paper presents confidence intervals (CIs) for the ratio of coefficients of variation (CVs) of inverse Gaussian distribution. To estimate this, we propose the following methods the fiducial confidence interval (FCI), the fiducial - highest posterior ...

Exploring the Expanding Universe and Dark Energy using the Statefinder Diagnostic [PDF]

, 2003
The coming few years are likely to witness a dramatic increase in high quality Sn data as current surveys add more high redshift supernovae to their inventory and as newer and deeper supernova experiments become operational.

Fiducial theory and optimal inference

, 2013
It is shown that the fiducial distribution in a group model, or more generally a quasigroup model, determines the optimal equivariant frequentist inference procedures.
