In a complex medium like a cell nucleus a single, distinct diffusion coefficient was not expected and the equation above allowed a multi-component analysis of the in vivo data.
The Brusselator model further revealed the "secret" of Turing patterns: a coupling between nonlinear reaction kinetics and distinct diffusion rates such that the inhibitor should diffuse more rapidly than the activator [ 16].
This paper investigates a white matter model consisting of a matrix of coated cylinders with distinct diffusion coefficients and spin concentrations for each of the cylinder core, the coating, and the surrounding bath and compares results with an the analytical solution developed by Sen and Basser for the long diffusion time limit.
The final dataset consists of approximately 6.5 million in-brain voxels, and 121 distinct diffusion measurements per voxel, for a total data volume of nearly 800 million points.
X-EDS analysis reveals that no less than seven distinct diffusion zones arise between Ti-6Al-4 V and a WC-Co tool which are home to different phases and reaction species.
Different crystallographic structures of the lipid mesophase give access to different diffusion coefficients and distinct diffusion modes.
Distinct diffusion flame structures were observed visually above the ported samples at 1 atm.
When this value is reached at any depth of the diffusion zone, two distinct diffusion zones will appear.
Two distinct diffusion regions, near-surface and far-surface regions, were identified in the dopant concentration profiles, indicating different diffusion mechanisms in these two regions.
(2) A new finding (not seen previously in the UV) is that for pure binder systems at relatively low pressures (<15atm), IR imaging clearly shows two stream-wise distinct diffusion flames, which are possibly the primary diffusion flame (PDF) and final diffusion flame (FDF) structures postulated in the BDP model.
While the diffusion coefficient extrapolated from the MSD gives insights into the total displacement, the Fourier transform of the ACF shows two distinct peaks clearly corresponding to distinct diffusion mechanisms, which are attributed to rotation and transfer.
