Abstract This work describes a method for calculating cluster membership probability from big, high dimensional newly released GAIA-EDR3 observations that combine the Gaussian Mixture Model (GMM) with Random Forest (RF). technique has considerable advantage of rapidly identifying possible members in big data sets using modest training samples. The result indicates double clusters NGC 869 20270 ...

Abstract Transcatheter aortic valve implantation (TAVI) has revolutionized the treatment of patients with severe, symptomatic stenosis. Despite being less invasive than conventional open-chest surgery, TAVI remains associated rare but serious complications such as vascular injury, stroke, coronary obstruction, cardiac perforation and annular rupture. We report a case combined rupture successful...
