Schooling fish often self-organize into a variety of collective patterns, from polarized schooling to rotational milling. Mathematical models support the emergence of these large-scale patterns from local decentralized interactions, in the ...
Morphlight theory inspired by raptor: bionic design and dynamics experiments of the morphing flight vehicle inspired by the Aquila nipalensis [0.03%]
受鹰类启发的变形飞行器仿生设计及机动性实验研究——形态光论初探
Di Tang,Yibo Zhao,Kunpeng Wang et al.
Di Tang et al.
Bird forelimbs exhibit complex flight kinematics, including wing morphing and flapping motions with angle asymmetry. However, data on angle-asymmetric flapping in birds are scarce, and well-established theories and methods remain limited. M...
Print, pattern, stick: Low-cost gecko-inspired adhesives using embedded diffraction structures [0.03%]
