Vortex Lattice Simulations of Attached and Separated Flows around Flapping Wings

open access: yesAerospace, 2017
Flapping flight is an increasingly popular area of research, with applications to micro-unmanned air vehicles and animal flight biomechanics. Fast, but accurate methods for predicting the aerodynamic loads acting on flapping wings are of interest for ...

Detecting wing fractures in chickens using deep learning, photographs and computed tomography scanning [PDF]

open access: yesPoultry Science
Animal welfare monitoring is a key part of veterinary surveillance in every poultry slaughterhouse. Among the animal welfare indicators routinely inspected, the prevalence of wing fractures and soft tissues injuries (e.g.

Biocompatibility and biosafety of butterfly wings for the clinical use of tissue-engineered nerve grafts

open access: yesNeural Regeneration Research, 2021
In a previous study, we used natural butterfly wings as a cell growth matrix for tissue engineering materials and found that the surface of different butterfly wings had different ultramicrostructures, which can affect the qualitative growth of cells and

How the monarch got its spots: Long-distance migration selects for larger white spots on monarch butterfly wings.

open access: yesPLoS ONE, 2023
Elucidating the adaptations that promote flight in animals can aid the understanding of evolution and species divergence, and/or provide inspiration for aerospace engineering and the design of better aerial vehicles.

Butterflies fly using efficient propulsive clap mechanism owing to flexible wings

open access: yesJournal of the Royal Society Interface, 2021
Butterflies look like no other flying animal, with unusually short, broad and large wings relative to their body size. Previous studies have suggested butterflies use several unsteady aerodynamic mechanisms to boost force production with upstroke wing ...

Signatures of increasing environmental stress in bumblebee wings over the past century: Insights from museum specimens

open access: yesJournal of Animal Ecology, 2022
Determining when animal populations have experienced stress in the past is fundamental to understanding how risk factors drive contemporary and future species' responses to environmental change.

The Beast Within, the Beast Without

open access: yesVenezia Arti, 2023
Drawing on and accentuating classical motifs, the surfaces of Renaissance armour are inhabited by an impressive variety of animal exuviae: leonine protomes and paws, ram’s horns, shells, tails, beaks, and wings.

Deep learning approaches to landmark detection in tsetse wing images.

open access: yesPLoS Computational Biology, 2023
Morphometric analysis of wings has been suggested for identifying and controlling isolated populations of tsetse (Glossina spp), vectors of human and animal trypanosomiasis in Africa.

Genomic adaptations to aquatic and aerial life in mayflies and the origin of insect wings

open access: yesNature Communications, 2020
The evolution of winged insects revolutionized terrestrial ecosystems and led to the largest animal radiation on Earth. However, we still have an incomplete picture of the genomic changes that underlay this diversification. Mayflies, as one of the sister
