An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

Identifying the exposure of taxonomic, functional, and phylogenetic diversity of steppe birds to renewable energy development

Conservation Biology, EarlyView.
Abstract Biodiversity is globally threatened by human impacts, including land‐use transformation and climate change, which has prompted a rapid transition from fossil fuels to cleaner energy sources, such as photovoltaic (PV) energy. However, utility‐scale PV plants require vast areas and can lead to conflicts with biodiversity conservation, making ...

Beyond the breeding grounds: identifying post‐breeding staging areas, corridors and ecological niche of the Lesser Kestrel

Ibis, EarlyView.
The post‐breeding period is a critical yet overlooked phase in the annual cycle of migratory birds, where individuals must resolve competing bioenergetic trade‐offs between recovery from breeding, moult and migratory fuelling. Using GPS data from 54 adult Lesser Kestrels Falco naumanni tracked across Spain, we analysed 76 post‐breeding tracks to ...

Moonlight Duration and Intensity Favour Nocturnal Activity in a Diurnal Desert Bird

Ethology, Volume 132, Issue 9, Page 629-641, September 2026.
Accelerometer data show that Canarian houbara bustards increase nocturnal activity two‐ to fivefold when the moon is visible, with activity rising as moonlit duration and illumination increase. Both display and non‐display behaviours peaked around full moon, reaching up to half of peak daytime levels, with males increasing visual displays during ...

Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.

Fourier Expansion‐Based Approach to the Parameter Space of Classical Systems

Annalen der Physik, Volume 538, Issue 7, July 2026.
ABSTRACT We propose a new approach to compute the classical metric tensor (CMT) and the Hannay curvature using Fourier series expansions in action‐angle variables. This approach circumvents the need for complex time‐domain integrals or the construction of generating functions, replacing them with algebraic combinations of Fourier coefficients. We prove
