The Effect of Spanwise Folding on the Aerodynamic Performance of a Passively Deformed Flapping Wing

Biomimetics
The wings of birds exhibit multi-degree-of-freedom motions during flight. Among them, the flapping folding motion and chordwise passive deformation of the wings are prominent features of large birds in flight, contributing to their exceptional flight ...

Lattices of hydrodynamically interacting flapping swimmers

, 2019
Fish schools and bird flocks exhibit complex collective dynamics whose self-organization principles are largely unknown. The influence of hydrodynamics on such collectives has been relatively unexplored theoretically, in part due to the difficulty in ...

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

Effects of deformation and vibration characteristics of wings on flapping flight

Mechanical Engineering Journal, 2015
The dragonfly wing is passively deformed under flapping and has the strength to withstand high flapping frequency simultaneously. These characteristics of deformation and vibration of the wing are important for flapping flight.

A Fully Discrete Adjoint Method for Optimization of Flow Problems on Deforming Domains with Time-Periodicity Constraints

, 2016
A variety of shooting methods for computing fully discrete time-periodic solutions of partial differential equations, including Newton-Krylov and optimization-based methods, are discussed and used to determine the periodic, compressible, viscous flow ...

Experiences of Māori After Stroke in Regional Aotearoa New Zealand: A Qualitative Study Informing Culturally Responsive Stroke Services

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.
Māori experience stroke at higher rates, face inequities in care and have poorer outcomes than non‐Māori in Aotearoa New Zealand. Guided by Kaupapa Māori research principles, this qualitative study explored Māori experiences of stroke and stroke services in two rural regions, Tairāwhiti and Wairarapa, and potential areas for improvement in stroke ...
