Dynamics of Thermalization in classical three-dimensional many-body systems: non-Maxwellian distributions and the role of anisotropic trapping
Roberto Onofrio and Bala Sundaram
The physics of interacting baths is of interest in a variety of contexts, ranging from ultracold atoms to ionized gases. While many features can already be captured in a one-dimensional model, others are speci c to the situation of two or three-dimensional systems. In this paper, we focus on three-dimensional features of a model for thermalization between two baths that we have explored in earlier publications. In contrast to the one-dimensional situation we show that, enroute to thermalization, deviations from the Maxwell-Boltzmann energy distributions more akin to -distributions are observed. In three dimensions, these can be seen in changes at the peak of the distribution, which is precluded by the expected monotonic behavior of the energy distributions in one dimension. Furthermore, we consider thermalization for anisotropic trapping and explore its role in the onset of anomalous scaling with respect to the particle number. These results may be pertinent to the understanding of the interplay between turbulent behavior and nonlinearities for a variety of many-body classical systems.
Data is from the figures in this study generated by numerical integration of classical equations of motion using a variable step predictor-corrector method. The single zip file contains data and other zipped data files associated with the figures in the paper.

Sex Identification of Mytilus edulis following 26 day treatment to EE2 and KZ
Helen C. Poynton and K. Garrett Evensen
Blue mussel M. edulis were exposed for 26 days to 50 ng/L 17alpha-ethinylestradiol or 30 ug/L ketoconazole for 26 days in four replicate tanks. Prior to exposure, mussel sex was identified using the VERL-VCL RT-qPCR assay on hemolymph collected from each mussel. Following exposure, mantle tissue was collected from each treated mussel and the VERL-VCL RT-qPCR assay was used to identify the sex of the mussels.
