Generating Helical Polymorphic Beams Using Dielectric Metasurfaces

Laser &Photonics Reviews, EarlyView.
Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic

Social‐ecological sustainability of olive farming in the Mediterranean: A review of current practices and an agroecological perspective

People and Nature, EarlyView.
Abstract Olive farming represents a prime example of a biodiversity‐rich land‐use system in the Mediterranean, deeply rooted in a long history and cultural traditions, yet it faces mounting challenges from climate change, biodiversity loss, and declining economic viability that put its sustainability at risk.

The value of regeneration

People and Nature, EarlyView.
Abstract Millions of hectares of rangelands have been subject to degeneration through overgrazing, agricultural expansion, urbanisation and afforestation. Countering this, regeneration is a natural process whereby rangeland ecosystems revive themselves.

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

On Relative Tractor Bundles

Symmetry, Integrability and Geometry: Methods and Applications
This article contributes to the relative BGG-machinery for parabolic geometries. Starting from a relative tractor bundle, this machinery constructs a sequence of differential operators that are naturally associated to the geometry in question. In many situations of interest, it is known that this sequence provides a resolution of a sheaf that can ...

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

Pest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.
