Introduction: Diffusion in brain tissue is well known to be non-Gaussian, resulting in major efforts to understand the biophysical basis of water mobility in such tissues [1]. This study aims to understand the energetics of differently diffusing components by quantification of their respective activation energies. When temperature is varied, self-diffusion in pure liquids follows the Arrhenius ...

We extend our recent simulation studies where a screw dislocation in face-centered cubic (fcc) Ni was found to spontaneously attain a low energy partially cross-slipped configuration upon intersecting a forest dislocation. Using atomistic (molecular statics) simulations with embedded atom potentials, we evaluated the activation barrier for a dislocation to transform from fully residing on the g...

Intermetallics disappearance rates and intrinsic diffusivities ratios in the Cu-Zn system at temperature 400oC Cu-Sn temperatures from 190oC to 250oC are analyzed theoretically using literature experimental data. Diffusion activation energies pre-exponential coefficients for calculated combining results.

Variation in resource supply can cause variation in temperature dependences of metabolic processes (e.g., photosynthesis and respiration). Understanding such divergence is particularly important when using metabolic theory to predict ecosystem responses to climate warming. Few studies, however, have assessed the effect of temperature-resource interactions on metabolic processes, particularly in...
