This paper investigates the influence of non-equilibrium evaporation on the properties of the critical flow of vapour-liquid mixture. As the non-equilibrium vapour generation is assumed to be dominant in a vapour-liquid flow, the Homogeneous Relaxation Model (HRM), with non-equilibrium mass transition, is selected and reduced to the equation for the linear pressure waves. Basing on this equation, the evolution of linear pressure wave in the non-equilibrium, two-phase mixture has been calculated. The conclusions coming from this calculations created a background for the concept of the pseudo-critical flow. A short description of the pseudo-critical flow regime is given and the main difference between the critical flow of equilibrium and non-equilibrium fluid are discussed. Finally, the remarks concerning a kind of relativity of the critical flow for non-equilibrium fluids are given.

On (4, 6, 12) and (4, 82) Archimedean lattices, the critical properties of the majority-vote model are considered and studied using the Glauber transition rate proposed by Kwak et al. [Kwak et al., Phys. Rev. E, 75, 061110 (2007)] rather than the traditional majority-vote with noise [Oliveira, J. Stat. Phys. 66, 273 (1992)]. We obtain T c and the critical exponents for this Glauber rate from extensive Monte Carlo studies and finite size scaling. The calculated values of the critical temperatures and Binder cumulant are T c = 0.651(3) and U 4* = 0.612(5), and T c = 0.667(2) and U 4* = 0.613(5), for (4, 6, 12) and (4, 82) lattices respectively, while the exponent (ratios) β/ν, γ/ν and 1/ν are respectively: 0.105(8), 1.48(11) and 1.16(5) for (4, 6, 12); and 0.113(2), 1.60(4) and 0.84(6) for (4, 82) lattices. The usual Ising model and the majority-vote model on previously studied regular lattices or complex networks differ from our new results.

Cell culture is a convenient model for pharmacokinetic studies, but during the culture period, GABAa receptors are likely to undergo different modulatory processes. In this study, the current responses to ultrafast GABA applications were recorded from patches excised from neurons cultured for either up to two days (short-term culture) or for more than two weeks (long-term culture). The dose-dependencies of the currentrising phases revealed significant differences between the two groups. In the short-term cultures, the responses to both saturating and non-saturating GABA concentrations were slower than in the case of the long-term cultures. We conclude that the GABAa receptors in cultured neurons undergo profound kinetic changes involving the modulation of the binding reaction and transitions between bound states.
