To tread or not to tread: comparison between water treading and conventional flapping wing kinematics [PDF]
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.

Bone construction surgery: A case report using recombinant human platelet‐derived growth factor‐BB
Abstract Background The position and condition of bone largely sets the stage for functional and esthetic implant success. In bone construction surgery, creating a sustainable functional matrix is complex, but necessary, to enable long‐term mechanotransduction and maintenance of soft tissue support.

Scalp reconstruction with supragaleal flap: a great option for large scalp avulsion [PDF]
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 Novel Framework for Optimizing Gurney Flaps using RBF Neural Network and Cuckoo Search Algorithm [PDF]
Enhancing aerodynamic efficiency is vital for optimizing aircraft performance and operational effectiveness. It enables greater speeds and reduced fuel consumption, leading to lower operating costs. Hence, the implementation of Gurney flaps represents a promising avenue for improving airfoil aerodynamics.

Feather-inspired flow control: The flow physics of spatially distributed covert flaps [PDF]
This study presents a novel spatially disrupted flow control system inspired by the covert feathers on bird wings. The system is a passive flow control system consisting of multiple feather-inspired flaps that dynamically interact with the surrounding flow to mitigate stall.
