Theory of non-local transport has been developed, taking an example of zonal flows (ZFs), the radial correlation length of which is longer than those for microscopic fluctuations. ZF, which is driven by fluctuations at one radius, can suppress fluctuations at distant radii. This mechanism induces new non-local interactions in turbulent transport. That is,(More)
The purpose of this investigation was to analyze three-dimensional images of the optic nerve obtained by magnetic resonance angiography (MRA) in cases of anterior communicating artery aneurysm and craniopharingioma. Four ruptured anterior communicating artery aneurysms, five non-ruptured anterior communicating artery aneurysms and two craniopharingiomas(More)
