Mapping axon diameter is of interest for the potential diagnosis and monitoring of various neuronal pathologies. Advanced diffusion-weighted MRI methods have been developed to measure mean axon diameters non-invasively, but suffer major drawbacks that prevent their direct translation into clinical practice, such as complex non-linear data fitting and, more importantly, long scanning times that ...
based on the importance of drops' behavior in liquid-liquid extraction, the maximum sauter mean drop diameter has been investigated and correlated in a counter-current spray extraction column with two chemical systems. spargers were set of nozzles in all experiments. studying the effects of several parameters on drops size, some correlations were estimated by the last available version of softw...
Background: Multiple sclerosis (MS) is a chronic disease of the central nervous system. As an association between MS and reduced cerebral venous blood drainage was hypothesised, our aim was to compare the size of the jugular foramina in patients with MS and in control subjects. Methods: Ethics committee approval was received for this retrospective case–control study. We collected imaging and cl...
We predict mean angular diameters and amplitudes of angular diameter variations for all monoperiodic Population I Cepheids brighter than 〈V 〉 = 8.0 mag. The catalog is intended to aid selecting most promising Cepheid targets for future interferometric observations.
Let M be a compact Riemannian manifold. For x, y G M, denote by p(x,y) the distance between x and y, i.e., the infimum of lengths of continuous piecewise C paths between x and y. (Notice that for geodesically complete manifolds there is always a path from x to y of length p(x,y).) The invariants of M based on the distance p are called metrical invariants. Most of them are related to the geometr...
Given a closed m-dimensional manifold M immersed in R, we estimate its diameter d in terms of its mean curvature H by
