Direct observations of individual molecules at high speed and resolution (e.g., single particle tracking) will likely be required to investigate how AA, CC, and SS erythrocytes differ in the distribution and diffusion patterns of membrane components.
The panels of the figure differ in the number of diffusion steps per generation: Panel A: D = 0, Panel B: D = 1, Panel C: D = 4 and Panel D: D = 100.
Tracer diffusion and chemical diffusion differ in the level of adsorbate coverage at the surface, while intrinsic diffusion and mass transfer diffusion differ in the nature of the diffusion environment.
In a situation that does not differ in the essentials from e.g. diffusion-influenced reactions in solution, slow protein conformational changes taking place along the reaction pathway could, in principle, reduce the value of the observed rate constant to a degree dependent on the rate of those changes.
These programs differ in the specifics of their approach to modeling the AFS, using either diffusion approximation [ 4, 6] or coalescent simulations [ 5, 7] to model the density of SNPs in cells of the AFS.
Skin in vitro models differ in the type of the skin membrane (full thickness skin vs. dermatomed skin), species (human vs. animal skin), vehicle and type of the diffusion cell, which hampers comparison and interpretation of the results.
How the systems differ in the UK.
All cars differ in the particular order.
In a system with multiple components, for example two components that differ in their diffusion properties, the autocorrelation function assumes a more complex shape (Fig. 6D).
These three test compounds differ in their diffusion coefficient by up to a factor of five but were cleared from brain according to a single exponential rate constant.
