Steryl esters (SEs) serve as a storage pool of sterols that helps to maintain proper levels of free sterols (FSs) in cell membranes throughout plant growth and development, and participates in the recycling of FSs and fatty acids released from cell membranes in aging tissues.SEs are synthesized by sterol acyltransferases, a family of enzymes that c
Abstract This work explores the extraction of the spatial distribution and chemical composition information of pigments in colored relics through visible spectral images.An adaptive superpixel segmentation method is proposed to extract the spatial distribution information of pigments.Quadtree decomposition is applied to generate nonuniform initial
This study describes the methodology employed to construct a seismic fragility function based on a pre-existing numerical model tailored for underground stations.Employing a dynamic numerical model, a comprehensive analysis encompassing 110 distinct cases was conducted, each varying in soil depth and classification.Seismic waves, conforming to the
The emergence of the Internet and web technologies has magnified the occurrence of disinformation events and the dissemination of online fake news items.Fake news is a phenomenon where fake news stories are created and propagated online.Such events occur with ever increasing frequency, they reach a wide audience, and they can have serious real-life
This study investigates the stability and phase difference of a shaft mounted a dry friction damper with effects of viscous internal damping and gyroscopic moment.The equations of the system with the vibration reduction effect of the dry friction damper on the shaft are derived in the form of the rectangular coordinate and polar coordinate in the v
