Sentence examples for used for diffusion from inspiring English sources

The procedure is based on the through diffusion method classically used for diffusion experiments.

A cross chaotic map proposed based on Devaney's theory and dynamic block dividing of the 3D baker using the cross chaotic map are used for diffusion and permutation in encryption.

An optimized six point icosahedral encoding scheme [113] was used for diffusion weighted acquisitions with a single un-weighted reference image for a total imaging time of 14.5 hours.

The parameters used for diffusion data acquisition were as follows: diffusion-weighting gradients applied in 60 directions with a b value of 1000 sec/mm2; repetition time/echo time of 5740/91 msec, field of view of 230×230 matrixatrix size of 128×128, resolution of 1.8×1.8×1.8 mm, 41 slices with no gap, covering the whole brain.

Artificial low-density polyethylene (LDPE, Key Container, Winnipeg, MB, Canada) membrane was also used for diffusion experiments; this membrane model possessed lipophilic properties.

Such an allowance would also allow for the distortions introduced by the EPI sequence used for diffusion data, although this is less of an issue for lesions that are not at the temporal pole.

Several non-EPI techniques, including conventional spin echo and stimulated echo and fast spin echo, have been used for diffusion-weighted imaging of the chest.

This separation by region is important to decide whether anisotropic or isotropic diffusion should be performed at each image pixel, and the directional estimates are important to determine which directional diffusion parameters are used for anisotropic diffusion at each pixel in the oriented region.

The calibration of the z-gradient coil used for the diffusion measurements was checked using the known diffusion coefficient for lysozyme (1.07 × 10−11 m/s) at 20 °C and a concentration of 5 mg/mL prepared in D2O [ 28].

This is a much lower particle density than the ∼150 ppb we have used for lipid diffusion measurements in previous reports and therefore the diffusion constants so measured are inherently less precise than those from our previous reports and our current protein diffusion measurements.

A pulsed field gradient stimulated echo (PFGSE) sequence with a 3 9 19 watergate solvent suppression (Bruker pulse sequence stbpgp 1s19) was used for the diffusion experiments at 27 °C with δ = 5.4 ms. Diffusion coefficients (Deff) were obtained for diffusion delays, Δ, between 50 ms and 1 s, as described in the Results and Discussion.
