Specific conductivities of local anesthetic heptacainium chloride XlX (HCC XlX) (N-[2-(2-heptyloxyphenylcarbamoyloxy)-ethyl]-piperidinium chloride), in aqueous electrolyte solution (0.05 mol.1−1 NaCl) were measured as a function of the concentration and temperature. The critical micelle concentrations (c.m.c) and the counterion (β) binding of the micelles were estimated from the dependence of the specific conductivity of the substrate concentration. The temperature dependence of ln c.m.c was fitted to the function of the second degree polynomial. From the fitting parameters, Gibss free energies (ΔG0), enthalpies (ΔH0), and entropies (ΔS0) of micellization as a function of temperature were estimated. The "mass action model" was applied to micelle formation to calculate the micellization parameters.

ABSTRACTA joint experimental and modelling programme is reported, which aims to improve our understanding of sorption processes of radionuclides onto repository materials. Diffusion/sorption experiments of sorption onto cement are described, although results are limited at this stage. The modelling studies use the coupled chemical equilibria and transport code CHEQMATE to simulate some of these experiments. The chemical part of the model is based on a simple mass-action model of sorption. More detailed comparisons will continue when the experiments are terminated, and the samples are sectioned.

This paper demonstrates a new time-delayed mass action model which applies a set of delay differential equations (DDEs) to represent the dynamics of gene regulatory networks (GRNs). The mass action model is a classical model which is often used to describe the kinetics of biochemical processes, so it is fit for GRN modeling. The ability to incorporate time-delayed parameters in this model enables different time delays of interaction between genes. Moreover, an efficient learning method which employs population-based incremental learning (PBIL) algorithm and trigonometric differential evolution (TDE) algorithm TDE is proposed to automatically evolve the structure of the network and infer the optimal parameters from observed time-series gene expression data. Experiments on three well-known motifs of GRN and a real budding yeast cell cycle network show that the proposal can not only successfully infer the network structure and parameters but also has a strong anti-noise ability. Compared with other works, this method also has a great improvement in performances.
