Dynamic response of a piezoelectric flapping wing
, 2015 Piezo-composite membranes have advantages over motorized flapping where frequencies are high and certain coupling between bending and twisting is useful to generate lift and forward flight. We draw examples of fruit fly and bumble bee.

High‐Speed Altitude Regulation With Neuromorphic Camera and Lightweight Embedded Computation
Advanced Intelligent Systems, EarlyView.Neuromorphic cameras deliver rapid, high‐dynamic‐range sensing but overwhelm embedded processors at high speeds. This work presents a lightweight, optimized Lucas–Kanade optical flow method with parallelization, gyroscopic derotation, and adaptive event slicing.

Deterministic Global Optimization of Flapping Wing Motion for Micro Air Vehicles
, 2010 The kinematics of a flapping plate is optimized by combining the unsteady vortex lattice method with a deterministic global optimization algorithm. The design parameters are the amplitudes, the mean values, the frequencies, and the phase angles of the ...

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats
The Anatomical Record, EarlyView.Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Face and Construct Validity of a Grapefruit Arthroscopy Training Model With Active Fluid Management
Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.Purpose To evaluate the face and construct validity of a grapefruit arthroscopy training model with active fluid management across varying levels of arthroscopic experience. Methods Orthopaedic residents, fellows, and attending surgeons were stratified into novice (n = 10), intermediate (n = 10), and advanced (n = 9) groups.

Classifying avian drinking behaviour: ecological insights and implications in a changing world
Biological Reviews, EarlyView.ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

On the Optimization Performance Study of Flapping Aerial Vehicle under Heavy Rain Condition
, 2020 Flapping-Wing Aerial Vehicle generally has light-weight and small size characteristics, and its small scale is particularly suited for surveillance mission, but quite fragile to severe weather impact. Here we consider the environmental effects to measure
