Angiopoietins 1−4 (Ang1−4) represent an important family of growth factors, whose activities are mediated through the tyrosine kinase receptors, Tie1 and Tie2.The best characterized are angiopoietin-1 (Ang1) Water Timer and angiopoietin-2 (Ang2).Ang1 is a potent angiogenic growth factor signaling through Tie2, whereas Ang2 was initially
Aims.To investigate a new method of left atrial appendage occlusion without fluoroscopy.Methods and Results.We performed left atrial appendage occlusion for 14 patients with atrial fibrillation in our hospital.All of the surgeries were completed in a general surgery setting, avoiding fluoroscopy, and in each case, the entire procedure was guided by
Moving cast shadows of moving objects significantly degrade the performance of many high-level computer vision applications such as object tracking, object classification, behavior recognition and scene interpretation.Because they possess similar motion characteristics with their objects, moving cast shadow detection is still challenging.In this Tr
Mugs Smooth orientation planning has an important influence on the working quality and service life as for industrial robot.Based on the logarithmic quaternion, a compact method to map a spline curve from Cartesian space to quaternion space is proposed, and consequently the multi-orientation smooth interpolation of quaternion is realized.Combining
We propose to organize a small basic Observatory aerospace monitoring of dangerous fireballs for a detailed study of the Earth interaction with space environment.During the observation from March 2013 to July 2014 we recorded fall at least a dozen of comet nuclei fragments, at least Doormat five large and dozens of smaller fragments of meteoroids.S
