This is manifested by regular undulations with no significant stenosis, which are reversible after injection of a vasodilator and/or removal of the catheter [43].
For example, the continuous twist between fibrils in compact bone osteons resembles a cholesteric mesophase, while in tendon, the regular, planar undulation, or "crimp", is akin to a precholesteric mesophase.
This treatment results in highly regular surface undulations.
Low-magnification SEM also showed the sheets to be uniform and regular with folds, wrinkles, and other undulations consistent with the light microscopy images.
Less studied effects of gravity are undulations due to the regular periodic change in the direction root tips grow, called waving, and the slanted angle of growth roots exhibit when they are growing along a nearly-vertical surface, called skewing.
When plants are grown on a solid surface, their roots show growth patterns of waving, which are undulations due to the regular periodic change in the direction root tips grow, and skewing, which is the slanted angle of growth roots exhibit when they are growing along a nearly-vertical surface.
Stracka's company, StrackaLine, creates and supplies the highly-detailed green guides that pros, amateurs and regular golfers use to get a better sense of undulation, slopes and which way balls will break on the greens.
On the other hand, the l p sparsity regularizations remove the undulations.
The undulations and oscillations may be chaotic and random, or they may be regular, with an identifiable wavelength between adjacent crests and with a definite frequency of oscillation.
For achieving the submicron undulation of surface topography, the laser holography on a photo-responsive azobenzene copolymer layer has been employed to produce surface relief grating (SRG) which has a regular sinusoidal shape.
A single undulation takes 10 million years to complete.
