We numerically study thermodynamic and structural properties of the one-component Gaussian core model at very high densities. The solid-fluid phase boundary is carefully determined. We find that the density dependence of both the freezing and melting temperatures obey the asymptotic relation, log T(f), log T(m)∝-ρ(2/3), where ρ is the number density, which is consistent with Stillinger's conjec...

A thermodynamic model of a compartment fire with one state variable (corresponding to the dimensionless temperature of the smoke layer) based on energy conservation is studied from the point of view of the Second Law (exergy analysis). To define the exergy rate of the process, a novel concept of mean thermodynamic temperature is introduced for the smoke layer. This parameter is the equivalent o...

Aspects of entropy and related thermodynamic analyses are discussed here that have been deduced in recent years in the area of classical electrodynamics. A motivating factor for most of this work has been an attempted theory of nature often called, “stochastic electrodynamics” (SED). This theory involves classical electrodynamics (Maxwell’s equations plus the relativistic version of Newton’s se...

Thermodynamics is an important driving factor for chemical processes and for life. Earlier work has shown that each cancer has its own molecular signaling network that supports its life cycle and that different cancers have different thermodynamic entropies characterizing their signaling networks. The respective thermodynamic entropies correlate with 5-year survival for each cancer. We now show...

The state of a thermodynamic system being characterized by its set of extensive variables q (i = 1, ..., n) , we write the associated intensive variables γi, the partial derivatives of the entropy S (q, ..., q) ≡ q0, in the form γi = −pi/p0 where p0 behaves as a gauge factor. When regarded as independent, the variables q, pi (i = 0, ..., n) define a space T having a canonical symplectic structu...

The size dependence and convergence rates of thermodynamic averages during Monte Carlo simulations of supercritical water in a wide range of densities have been analysed and compared with simulations under normal conditions. It is shown that the fluctuations of internal energy (enthalpy) in NPT-ensemble Monte Carlo simulations of high-temperature water are strongly correlated with fluctuations ...

Fibrosis is characterized by fibroblast proliferation and fibroblast differentiation into myofibroblasts, which generate a relaxation-free contraction mechanism associated with excessive collagen synthesis in the extracellular matrix, which promotes irreversible tissue retraction evolving towards fibrosis. From a thermodynamic point of view, the mechanisms leading to fibrosis are irreversible p...
