Determinants of heart rate variability Objectives. This study sought to examine clinical determinants of heart rate variability and to report normative reference values for eight heart rate variability measures. Background. Although the clinical implications of heart rate variability have been described, clinical determinants and normative values of heart rate variability measures have not been studied

Different from the traditional theory of irreversible thermodynamics, a novel approach has been provided for calculating the entropy associated with irreversible processes. It allows for a clear relation, in terms of observable properties, between heat and work transfers in irreversible processes and those in reversible changes. The same technique is applied to thermodynamic state construction

In order to investigate molecular interactions and cluster parameters, a computer-aided analysis of thermophysical data from electronic databases for pure gases has been developed. As an advanced forum for education in thermodynamics, pure gases can be used. This method is based on the corresponding expansion of thermophysical values by degrees of monomer fraction density in

In wind flows, natural and anthropogenic particles can travel long distances, but negative electrical charge can increase dispersion due to friction. As can be seen by disasters such as Chernobyl in Russia with around 6000 kilometres or the Daiichi nuclear power plant disaster in Fukushima, Japan, which covers almost the entire Northern Hemisphere or more

The sensitivity of gravitational wave interferometric detectors is ultimately limited by the quantum noise, which arises from the quantum nature of light and it is driven by vacuum fluctuations of the optical field entering from the dark port of the interferometer. One way to improve the sensitivity of gravitational wave interferometers is to inject squeezed
