Study of efficient fluid-structure interaction analysis for morphing wing with corrugated structures

Nihon Kikai Gakkai ronbunshu, 2019
Morphing wings, which control the flight by changing their own shapes, have attracted much attention by their potential for improving aerodynamic performance. Corrugated structures, which have flexibility in the corrugation direction and high rigidity in

Emotional Valence Influences Empathic Capacity in Adolescence and Young Adulthood

Journal of Adolescence, EarlyView.
ABSTRACT Introduction Previous research has identified age‐related differences in empathic abilities between adolescence and young adulthood. While cognitive empathy appears to continue to develop from adolescence and into adulthood, the developmental trajectory of affective empathy is less clear.

Beyond the Classics: The Synergy of AI and Genomics Reveals an Expanded Repertoire of Pigmentation Genes

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Classical approaches for coloration analysis are limited by human low‐resolution phenotyping and genetic analysis. Artificial intelligence allows us to find genes beyond the tip of the iceberg that explain color and pattern diversity in nature. ABSTRACT Pigmentation has long served as a powerful system for exploring gene–trait relationships, yet much ...

MR Imaging‐Based Biomarkers for Strength Prediction: A Statistical Shape and Architecture Modeling of Quadriceps Muscles

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Muscle mass decline, associated with strength decline, is a hallmark of aging. Yet, strength decline greatly exceeds mass decline. This indicates that aspects of muscle quality and architecture—not reflected by mass—also influence force generating capacity.

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.

Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

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

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.
