The Not‐So‐Neue Frau: Weimar Berlin's Modern Women and Generational Identity After 1945

Gender &History, EarlyView.
ABSTRACT This article studies the post‐1945 literary careers of Gabriele Tergit and Ilse Langner, two ageing German writers. Both had enjoyed promising careers as young women in Weimar Berlin, but Nazism and war disrupted their professional trajectories in varying ways. After 1945, they tried and failed to recapture their Weimar‐era success, eventually

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats

Integrative Zoology, EarlyView.
Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...

An Efficient SDOF Sweep Wing Morphing Technology for eVTOL-UAV and Experimental Realization

Drones
The presented study demonstrates that UAVs can be flown with a morphing wing to develop essential aerodynamic efficiency without a tail structure, which decides the operational cost and flight safety.

Designing a Morphing Wing for Fixed-Wing UAVs By IJISRT

International Journal of Innovative Science and Research Technology (IJISRT)
This project report details the original conceptualization, design, and analysis of a morphing wing structure for fixed-wing Unmanned Aerial Vehicles (UAVs). Our approach incorporates an octahedron cell structure coupled with the application of shape memory alloys(SMAs) to facilitate controlled wing morphing.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

Agricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

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 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 ...
