The method requires diffusion data acquired by common, clinically feasible MRI sequences, and is able to derive familiar tensor quantities for each compartment.
Co-mingling of material on a molecular scale requires diffusion, and the droplet model provides a convenient representation of such micromixing.
It is proposed that the low diffusivity of such heavy elements retards these diffusion-controlled phase transformations (feathery and lamellar) so that the massive transformation, which does not require diffusion, but which occurs at a lower temperature can take place.
This implies that if oxygen vacancies are generated at the surface of the catalyst by reaction with propene, these vacancies will be directly filled by gas phase reaction without requiring diffusion of oxygen from the bulk.
After passing through the SPF, LA would enter the sphenopalatine fossa, which is filled with adipose tissue requiring diffusion of the LA through adipose and connective tissue in order to reach the SPG.
Most of the methods that have been proposed to resolve this problem require diffusion magnetic resonance imaging (MRI) data that comprise large numbers of angles and high b-values, making them problematic for routine clinical imaging and many scientific studies.
Distribution function fine structure is tolerated and the formalism does not require diffusion of the distribution function, The VHS method is particularly valuable when the flux of phase fluid across the phase box boundary is significant.
The formation of a bound complex requires diffusion of integrins in the cell membrane to a ligand binding site, followed by integrin-ligand binding, and subsequent diffusion of plaque proteins to the integrin site for formation of the integrin-ligand-plaque protein complex.
They require diffusion rates that are proportional to the wave magnetic field intensity.
