Sentence examples for direction of the diffusion from inspiring English sources

In this work, we demonstrate analytically and numerically that this simplified approach may not honor the total flux balance and, in some applications, fails to capture the right direction of the diffusion flux.

These voxels were selected in this way because a high MRI signal is expected in white matter when the direction of the diffusion gradient is perpendicular to the tract's main direction.

Next, from each of these points a fiber starts growing with a fixed step size (arbitrarily chosen to be 1 mm) in two opposite directions, locally following the direction of the diffusion maximum which is the closest to the fiber trajectory.

The probability of successfully diffusing in a particular trial, pdiff, is multiplied by η if the direction of the diffusion move is toward the center, so that η > 1 will favor motion toward the center.

Multiple diffusion gradient directions are not necessarily useful as the liver appears isotropic with no demonstrable difference in reported ADC values related to the direction of the diffusion gradient [ 23].

Michael Moseley's group had made another great discovery: In the diffusion images, contrast seemed to change according to the spatial direction of the diffusion measurement in white matter (spinal cord and brain).

In this study, we investigated the possibility to indirectly infer the anisotropy of the capillary network in the healthy cerebral gray matter by evaluating the dependence of the IVIM signal from the direction of the diffusion-encoding.

If the direction of the diffusion-encoding gradient matches the principal direction of a white matter tract, the MR signal will be suppressed; the signal will remain intact or less suppressed if the white matter tract runs perpendicular to the diffusion-encoding gradient.

The effects of the energetic heterogeneity can be significant, depending on the mutual direction of diffusion (co-diffusion or counter-diffusion), the initial and final surface coverages, and the relative diffusivities of the components.

The change in chemical potential indicated the preferred directions for the diffusion of electroactive species from reactants to products and their relationship with a Coulombic point charge at the nanoelectrode surface.

The transport number of protons measured in a concentration cell was observed to depend on the direction of the proton diffusion flux through these membranes so that transport numbers of ca. unity were obtained when the cation exchange side faced the solution with higher proton concentration.
