Fluid-structure interaction of a bio-inspired passively deployable flap for lift enhancement [PDF]
arXiv, 2022 Birds have a remarkable ability to perform complex maneuvers at post-stall angles of attack. The passive deployment of self-actuating covert feathers in response to unsteady flow separation while performing such maneuvers provides a passive flow control paradigm for these aerodynamic capabilities. Most studies involving covert-feathers-inspired passive

Scalp reconstruction with supragaleal flap: a great option for large scalp avulsion [PDF]
Revista Brasileira de Cirurgia Plástica, 2017 The treatment of large scalp defects remains a big challenge, even though several therapeutic options are available. According to localization, size and depth of injury, and patient's characteristics, the plastic surgeon may use techniques such as skin ...

A flapping feathered wing-powered aerial vehicle [PDF]
arXiv, 2021 An aerial vehicle powered by flapping feathered wings was designed, developed and fabricated. Different from legacy flapping-wing aerial vehicles with membrane wings, the new design uses authentic bird feathers to fabricate wings. In field tests, a radio-controlled electric-powered aerial vehicle with flapping feathered wings successfully took off ...

To tread or not to tread: comparison between water treading and conventional flapping wing kinematics [PDF]
, 2022 Hovering insects are limited by their physiology and need to rotate their wings at the end of each back and forth motion to keep the wing's leading edge ahead of its trailing edge. The wing rotation at the end of each half-stroke pushes the leading edge vortex away from the wing which leads to a loss in the lift.

An innovative nipple reconstruction technique for minimizing postoperative scars: The teardrop flap [PDF]
Archives of Aesthetic Plastic Surgery, 2020 Nipple reconstruction methods include various techniques, such as the local flap technique, free nipple grafting, and filler injection. The local flap technique can provide less donor site morbidity than a free nipple graft, but leaves an additional scar
