Cosmology with Galaxy Clusters: I. Mass Measurements and Cosmological Parameters
Under the assumption that the gas mass fraction of galaxy clusters estimated out to an outer hydrostatic radius is constant, it is possible to constrain the cosmological parameters by using the angular diameter distance relation with redshift. We applied this to a sample of galaxy clusters from redshifts of 0.1 to 0.94, for which published gas and total masses are available from X-ray data. Aft...
متن کاملKinematic and kinetic parameters associated with running in different shoes.
The characteristics of the midsole were examined in four pairs of running shoes by a materials test. The variables of interest were the peak acceleration, time to peak acceleration and the kinetic energy absorbed. Ten subjects then ran at a recreational jogging pace (3.5 ms-1) barefoot and in the shoes. An accelerometer secured to the lower tibia was used to measure the peak acceleration and ti...
متن کاملBiased Cosmology: Pivots, Parameters, and Figures of Merit
In the quest for precision cosmology, one must ensure that the cosmology is accurate as well. We discuss figures of merit for determining from observations whether the dark energy is a cosmological constant or dynamical, with special attention to the best determined equation of state value, at the “pivot” or decorrelation redshift. We show this is not necessarily the best lever on testing consi...
متن کاملComparison of Ground Reaction Force Components during Running with Running Shoes and Control Shoes in Individuals with Genu Varum
Introduction: Running poses an essential role in maintaining cardiovascular health. However, it has been demonstrated that 2.5 to 38 injuries per 1,000 hours of running can occur. The purpose of this study was to investigate ground reaction forces components during running with running shoes compared to control shoes in individuals with genu varum. Methods: This study was laboratory and semi-e...
متن کاملCosmology with variable parameters and effective equation of state for Dark Energy
A cosmological constant, Λ, is the most natural candidate to explain the origin of the dark energy (DE) component in the Universe. However, due to experimental evidence that the equation of state (EOS) of the DE could be evolving with time/redshift (including the possibility that it might behave phantom-like near our time) has led theorists to emphasize that there might be a dynamical field (or...
