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.

Handling Everyday Life: An Analysis of Ordinary Acting

Theoria, EarlyView.
ABSTRACT What does it mean to shape one's own everyday life and to be the author of one's ordinary acting with all its repetitions, anchored habits and well‐known practices? In this paper, I argue that moral philosophy should pay more attention to human agency in quotidian contexts.

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 ...

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.

Generalization for both diurnal and nocturnal pollination in the mass‐flowering desert geophyte Nerine laticoma (Amaryllidaceae)

Plant Biology, Volume 28, Issue 2, Page 468-478, March 2026.
Both diurnal and nocturnal pollinators are important in the desert plant Nerine laticoma. Abstract The evolutionary limits to generalization in plant pollination systems are often determined by trade‐offs in which adaptations to one set of flower visitors reduces the effectiveness of another set of visitors.
