Objective—To determine preoperatively, by analysing asynchronous left ventricular wall motion, whether to approach through the right ventricle or the left ventricle when carrying out catheter ablation of the accessory pathway in WolVParkinson-White syndrome, especially in patients with the pathway located on the septum. Methods—73 patients with manifest WolV-Parkinson-White syndrome who underwe...

In 4D printing, structures with gradients in physical properties are 3D printed order to dramatically increase deformation. For example, printing bilayer passive and active layers has been proposed, however, these methods have the disadvantages that material of each layer is mixed, modeling process complicated. Herein, we present a method creating gradient gels different degrees polymerization ...

The transfer of atmospheric kinetic energy to the ocean is one major concerns in climate research. According previous studies, work wind stress on oceanic mesoscale eddy negative most oceans, referred as “eddy killing”. However, another recent work, finds that an varies with interaction time. To better understand eddies, present study uses satellite remote sensing data and from 2000 2021 invest...

Our purpose is to detect ocean surface features, specifically oceanic thermal fronts, through analysis of SAR (synthetic aperture radar)-derived wind stress fields. Fine-resolution measurements of near-surface wind speeds over the Gulf Stream region of the Northwest Atlantic were made using SAR images collected by RADARSAT-2. Linear statistical relationships between the wind stress curl and div...

Given a sequence of Galerkin spaces Xh of curl conforming vector fields, we state necessary and sufficient conditions under which it is true that the scalar product uh ·uh of two sequences of vector fields uh, uh ∈ Xh converging weakly in L, converges in the sense of distributions to the right limit, whenever uh is discrete divergence free and curluh is precompact in H−1. The conditions on Xh a...

A 50-year-old woman with aortitis syndrome complicated by aortic dissection, is reported. The dissection was observed at the level of the descending thoracic aorta by aortography and at the intimal side of the dilated aorta on CT. An aneurysm of the right subclavian artery and a diffusely thick wall of the abdominal aorta were also observed. This case suggests that the uneven wall of the aorta ...
