Homogenous pores with smooth diffusion could be obtained by oxygenation.
The frequency distributions of the marker displacements are also analysed and compared with a smoothed diffusion model.
This is likely because borehole temperature reconstructions are unable to capture sharp transitions such as the one from the cold Younger Dryas to the warm Holocene due to the smoothing effect by diffusion of heat in the ice-sheet (Methods).
Mesopores act as smooth channels for the diffusion of middle distillate molecule.
This is in contrast to the smooth surface model, where diffusion of the free buffer is unrestricted (Fig. 6c).
In the smooth surface model, reduced diffusion of buffered Ca2+ would have little effect on the peak Ca2+ concentration (Fig. 4a).
However, the increase in smooth muscle calcium does not necessarily reflect diffusion of endothelial calcium only.
Our simulations indicate that the distance between patch systems is more consistent when the inhibitory morphogen also inhibits the activator production of other types, because the fast diffusion of the inhibitor substance leads to smoother patches.
An effect that is not captured in the previous approximate methods is the diffusion of radiation through the cloud, which tends to smooth out density perturbations.
In addition to the mean flow and its implied shear, there is also inherently stochastic non-affine motion that is associated with diffusion of the particles and not describable in terms of a smooth deformation.
