Experimental Study on Dynamic Force–Thermal Loading for Multi-Stage Telescopic Wings Based on the Dynamic Multi-Point Equivalent Method

Applied Sciences
To address the challenge of simulating force–thermal environmental loads on morphing wings during flight, this study proposes and validates a force–thermal simulation method based on servo loading. First, the aerodynamic loads on a multi-stage telescopic

Democratising Multi‐Projector Displays

Computer Graphics Forum, EarlyView.
Spatially augmented reality (SAR) transforms large, surround, collaborative experiences out of VR/AR headsets to the real world by merging content from projectors with the physical environment. This detailed state‐of‐the‐art survey reports on the advancements in multi‐projector aggregation and hardware technologies used to achieve SAR and build ...

A review on true dung beetles' evolutionary and ecological responses to temperature and impacts on ecosystem functions

Ecological Entomology, EarlyView.
True dung beetles are a speciose group of ecosystem engineers that play key roles as detritivores in natural and agricultural landscapes. Scarabaeine beetles show strong thermal plasticity and there is increasing evidence of rapid evolutionary divergence in response to temperature across ecological and evolutionary timescales, with likely consequences ...

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

Artists in Nursery Schools: Enabling Free Play and Self‐Expression Through the Arts

International Journal of Art &Design Education, EarlyView.
Abstract The purpose of this research was to analyse the presence of artists in nursery schools by means of two proposals to promote free play and self‐expression for children between one and 3 years‐old and their families. Researchers compiled evidence from the perspective of three atelieristas and other participating adults, through interviews and ...

Differential Varietal Responses in Faba Bean Concerning Pea Aphid and Pea Necrotic Yellow Dwarf Virus (PNYDV) When Intercropped With Oat

Journal of Applied Entomology, EarlyView.
ABSTRACT The pest status of pea aphid (Acyrthosiphum pisum H.) in faba bean (Vicia faba L.) cultivation has gained importance because it transmits Pea necrotic yellow dwarf virus (PNYDV), a novel nanovirus in Europe. This study evaluated two faba bean varieties, ‘Fuego’ and ‘GL Sunrise’, grown under sole crop (SC) and intercrop (IC) conditions with oat
