Data from: Seasonal Alternation of Putative Camouflage Wing Morphs of the American Snout Butterfly (Libytheana carinenta) [PDF]
We defined and recorded ventral hindwing morphs of the American Snout butterfly, Libytheana carinenta, over its North American range. Local surveys were made in southern Arizona.

Moisture Effects on the Dimensional Stability of Bistable Carbon/Epoxy Laminates
Polymer Composites, EarlyView.Experimental and numerical approach for studying moisture effects on composite dimensional stability. ABSTRACT Bistable composite laminates are attractive because they can switch between two stable shapes without continuous energy input, enabling applications in morphing structures and energy harvesting devices.

PLANTS, PEOPLE, PLANET, EarlyView.Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

Wing dimorphism of Amantis nawai (Shiraki, 1908) (Mantodea: Mantidae): male A. nawai in Taiwan possesses two wing morphs [PDF]
, 2007 Yamasaki (1980) 指出台灣地區的名和異跳螳 (Amantis nawai (Shiraki, 1908)) 雄蟲為長翅型 (macroptera)，但日本卻只有微翅型 (microptera) 雄蟲存在，因此認為台灣與日本的名和異跳螳應屬於不同物種。實際上，台灣同時具有長翅型及微翅型雄蟲的分布。我們發現兩種翅型雄蟲不僅外表形態 (除了翅膀) 類似、生殖器形態也幾乎沒有差別，而且共域、分布季節重疊，更重要的是長、微翅型雄蟲子代可出自同一對親代。以粒線體 COII 序列建構的親緣關係樹、長 ...

Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae
Pest Management Science, EarlyView.Predator risk above a critical density induces winged morphs in Myzus persicae, promoting dispersal and reducing predation compared with wingless aphids. This density‐dependent phenotypic plasticity enhances survival but may compromise biological control by facilitating aphid dispersal.

Design of a composite morphing wing
, 2019 Morphing aircraft components can increase the possibility of optimising the performance of an aircraft at various flight conditions. A morphing aircraft wing can change the wing shape to modify the lift and drag distribution on the wing surface, allowing the lift-to-drag ratio to be tailored to the desired performance.

Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...
