 Context examples 


It is characterized by prominent serration of the glands and the presence of generalized low-grade dysplasia.

(Appendix Traditional Serrated Adenoma, NCI Thesaurus)

Researchers from Japan and China studied the serrations in the leading edge of owls’ wings, gaining new insight into how they work to make the birds’ flight silent.

(Owls' Wings Key to Beating Wind Turbine Noise, The Titi Tudorancea Bulletin)

Owls are known for silent flight, owing to their unique wing features, which are normally characterized by leading-edge serrations, trailing-edge fringes and velvet-like surfaces.

(Owls' Wings Key to Beating Wind Turbine Noise, The Titi Tudorancea Bulletin)

These owl-inspired leading edge serrations, if applied to wind turbine blades, aircraft wings or drone rotors, could provide a useful biomimetic design for flow control and noise reduction.

(Owls' Wings Key to Beating Wind Turbine Noise, The Titi Tudorancea Bulletin)

The researchers analyzed owl-inspired feather wing models with and without leading edge serrations, by combining large-eddy simulations – a mathematical model for turbulence used in computational fluid dynamics to simulate air flows – and Particle-Image Velocimetry (PIV) and force measurements in a low-speed wind tunnel.
