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

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 ...

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

Actuation Strategies for Underwater Jet‐Propelled Soft Robots
Journal of Field Robotics, EarlyView.ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Morphing of ‘flying’ shapes for autonomous underwater and aerial vehicles
, 2009 Autonomous vehicles are energy poor and should be designed to minimise the power required to propel them throughout their mission. The University of Southampton’s School of Engineering Sciences is actively involved in the development of improved designs ...

Physical Anchoring‐Assisted Mechanically Guided Assembly for Material‐Independent 3D Mesostructures
Small, EarlyView.Conventional mechanically guided 3D assembly relies on selective chemical bonding between 2D precursors and elastomeric substrates, imposing fundamental limitations on material compatibility and scalability. Here, we present a physically anchored, buckling‐guided assembly platform based on a rod array patterned elastomeric substrate (RPES).

Optimization of a Composite Wing Subject to Multi Constraints [PDF]
, 2013 In this thesis, an investigation has been carried out into a minimum weight optimization analysis of a composite wing with multi design constraints under both static and dynamic loadings. The study includes the influence of a morphing leading edge on the
