This Note investigates the approximation of phase change in compressible fluids with complex equation of state (EOS). Assuming a local and instantaneous equilibrium with respect to phasic pressures, temperatures and chemical potentials when both phases are present leads to the classical definition of an equilibrium EOS for the two-phase medium. Unfortunately, there is no explicit expression of ...

This paper extends the recent investigation of Tahvonen and Withagen (1996, Journal of Economic Dynamics and Control 20, 1775}1795) for costly and thus sluggish instead of instantaneous reductions in emissions. In addition to the social optimum, the paper investigates the competitive equilibrium. This plausible extension allows to derive limit cycles as the outcome for both, the social optimum ...

We consider the Fokker-Planck equation with a confining or anti-confining potential which behaves at infinity like a possibly high degree homogeneous function. Hypoellipticity techniques provide the well-posedness of the weakCauchy problem in both cases as well as instantaneous smoothing and exponential trend to equilibrium. Lower and upper bounds for the rate of convergence to equilibrium are ...

Flavor SU(3) is used for studying the time-dependent CP asymmetry in B → πKS by relating this process to B → ππ and B → KK. We calculate correlated bounds on SπK − sin 2β and CπK , with maximal magnitudes of 0.2 and 0.3, where SπK and CπK are coefficients of sin∆mt and cos∆mt in the asymmetry. Stronger upper limits on B → KK are expected to reduce these bounds and to imply nonzero lower limits ...

We prove that all deterministic hidden-variables theories, that reproduce quantum theory for an ‘equilibrium’ distribution of hidden variables, give instantaneous signals at the statistical level for hypothetical ‘nonequilibrium ensembles’. This generalises another property of de Broglie-Bohm theory. Assuming a certain symmetry, we derive a lower bound on the (equilibrium) fraction of outcomes ...

The simulated moving bed (SMB) technology, first conceived for large bulk-scale separations in the petrochemical industry, has found increasingly new applications in the pharmaceutical industry. Among these, the separation of fine chemicals has been the subject of considerable study and research. This work presents the modeling, simulation and design of the operation of a SMB plant in order to ...

AbatraetDynamic behavior of gas emboti in a quiescent liquid having the rheological properties of human or animal blood subject to pressure variations is studied. Consideration is given to step and sinusoidal changes in the system pressure. It is disclosed that in the study of dynamic behavior of gas emboli, a Newtonian model may be used to approximate the rheological behavior of human or anima...

Out-of-equilibrium systems can host phenomena that transcend the usual restrictions of equilibrium systems. Here we unveil how out-of-equilibrium states, prepared via a quantum quench, can exhibit a non-zero Hall-type response that persists at long times, and even when the instantaneous Hamiltonian is time reversal symmetric; both these features starkly contrast with equilibrium Hall currents. ...

We consider the instantaneous equilibrium (ieq) transition of an underdamped Brownian particle under arbitrary time-dependent temperature and potential variations derive analytic results for protocols minimal dissipative work. Explicit dissipation associated energetics are obtained cases pure variation, parameter (stiffness) isentropic ieq processes. The condition enforces forward backward to b...
