Aiming at the problems of poor decomposition quality and the extraction effect of a weak signal with strong noise by empirical mode decomposition (EMD), a novel fault diagnosis method based on cascaded adaptive second-order tristable stochastic resonance (CASTSR) and EMD is proposed in this Artificial Flora paper.In the proposed method, low-frequen
The tolerance mechanism based on dark channel prior (DCP) of a single image dehazing algorithm is less effective when there are large areas of the bright region in the hazy image because it cannot obtain the tolerance adaptively according to the characteristics of the image.It will lead to insufficient improvement of the transmission of image, so i
Background Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a less-invasive technique for aortic occlusion (AO).Commonly performed in the emergency department (ED), the role of intraoperative placement is less defined.We hypothesized that operating room (OR) placement is associated with increased in-hospital mortality.Methods Th
