The paper examines tail flaring in hummingbirds during male-male fights, finding greater tail flare angles during fights compared to non-aggressive maneuvers and field observations show tail flaring is common in contests.

The paper presents a coupled fluid-structure and systems biology model to simulate aortic valve calcification dynamics, showing fibrosis-induced stiffening accelerates calcification through altered biomechanical and biochemical pathways.
