objectives our aim was to study the relation between vac and the parameters of myocardial mechanics using three-dimensional speckle-tracking echocardiography (3dste). patients and methods we studied 68 normal participants (mean age, 35 ± 12.2 y; 36 [53%] males). vac was measured by the ratio of arterial elastance (ea) to ventricular elastance (ees). the peak systolic value of longitudinal strai...

The mechanical coupling between the eardrum and the manubrium was studied by means of a finite-element model of the cat eardrum. Previous calculations of the effect of varying the eardrum curvature were extended, demonstrating the critical role of curvature in the behavior of the eardrum. A new procedure was developed for directly studying the coupling of forces from different points on the ear...

We investigate a dynamical order induced by coupling and/or noise in systems of coupled oscillators. The dynamical order is referred to a one-dimensional topological structure of the global attractor of the system in the context of random skew-product flows. We show that if the coupling is sufficiently strong, then the system exhibits one dimensional dynamics regardless of the strength of noise...

The paper deals with three dimensional effects in tokamaks that can be approximated by slowly varying 3d equilibria so that their theoretical description and corresponding code developments can benefit from stellarator research. We investigate the effect of magnetic field ripple and perturbation fields (magnetic islands, external coils) on fast particle orbits in ITER and ASDEX Upgrade equilibr...
