The ice covering of transmission lines tends to cause flashover along the surface, and even topple the tower in serious cases, which seriously threatens the safe operation of the power grid. Here, a dual active and passive anti-icing strategy was des

BackgroundCholesterol crystals (CCs) in lesions are the hallmark of advanced atherosclerotic plaque. Previous studies have demonstrated that CCs could activate NLRP3 inflammasome, which played an important role in atherosclerotic lesion progression.

To improve the interpolation accuracy for the non-uniform rational B-spline (NURBS) curves, this paper proposes a novel bidirectional adaptive feedrate scheduling (BAFS) method based on S-shaped acceleration/deceleration (ACC/DEC) algorithm. The NURB
