Dynamic scaling in colloidal aggregation: Comparison of experimental data with results of a stochastic simulation

ABSTRACT Stochastic simulation can make the molecular processes of cellular control more vivid than the traditional differential equation approach by generating typical system histories, instead of just statistical measures such as the mean and variance of a population. Simple simulations are now easy for students to construct from scratch—that is, without recourse to black-box packages. In some cases, their results can also be compared directly with single-molecule experimental data. After introducing the stochastic simulation algorithm, this article gives two case studies involving gene expression and error correction, respectively. For gene expression, stochastic simulation results are compared with experimental data, an important research exercise for biophysics students. For error correction, several proofreading models are compared to find the minimal components necessary for sufficient accuracy in translation. Animations of the stochastic error correction models provide insight into the proofreading mechanisms. Code samples and resulting animations showing results are given in the online Supplemental Material.

The results of the analysis of experimental data concerning the sound absorption in the nitro-methane–n-pentanol and nitrobenzene-n-hexane solutions obtained in a wide frequency interval of 5–2800 MHz and measured along the isotherms and isoconcentrates, including their critical values, are presented. The detected anomalous dependences of the sound absorption coefficient were found to obey the laws of the dynamic scaling theory only in the fluctuation region of the problem parameters, wтfl ≫ 1. The sound frequency growth (f ≥ 110 MHz) in the examined frequency interval, as well as moving away from the critical temperature and concentration values, is proved to transit the system from the critical region into the crossover, wтfl ∼ 1, or even hydrodynamic, wтfl ≪ 1, one.
