One can measure the statistical alignment between the inclination angles of the disc and stellar spin using the projected rotational velocity, radius, and rotation period...

Magnetic activity is closely linked to stellar rotation, with stars exhibiting increasingly stronger activity as rotation rates increase. This activity reaches saturation at rapid rotation...

Our results also show that crop acreage diversity—which captures crop rotation diversity and, to a lesser extent, spatial crop diversity in our data...

Abstract Objectives Aortic root (AoR) rotation is a significant factor influencing the structures around the aortic valve and the atrioventricular conduction system. However, its relationship with the mitral valve remains unexplored. The goal of this study...
