Discrete Implementations Modify the Intuition of Final Set Adjustment in Barrier Function Based Control

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper establishes an implementation‐aware framework for Barrier Function Adaptation (BFA) and shows that discrete‐time realizations fundamentally alter the logic of final‐set adjustment. In particular, sufficient conditions are derived to preserve the key benefits of BFA (predefined performance, gain adaptation with uncertain perturbation

Semi-Huber quadratic function and comparative study of some MRFs for Bayesian image restoration [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2013
The present work introduces an alternative method to deal with digital image restoration into a Bayesian framework, particularly, the use of a new half-quadratic function is proposed which performance is satisfactory compared with respect to some other ...

Green Hydrogen as a Sustainability Transition in Spain: Motivations and Implications for Energy Governance

open access: yesSustainable Development, EarlyView.
ABSTRACT Green hydrogen has emerged as a strategic component of Spain's decarbonization agenda, with the country leveraging its renewable energy potential and industrial capabilities to align with the European Union's climate goals. Drawing on a multidimensional theoretical framework, this article examines the key drivers shaping Spain's green hydrogen

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

open access: yesHigh 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

open access: yesConservation 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

open access: yesIbis, 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 ...

Framing the Square: Cinematic Procedures and Visual Regimes in Diamela Eltit's Lumpérica

open access: yesBulletin of Latin American Research, Volume 45, Issue 4, October 2026.
ABSTRACT This article examines how Diamela Eltit's Lumpérica (1983) constructs a regime of visibility through the spatial organisation of the public square that structures the novel. While criticism has often emphasised the text's linguistic fragmentation and performative dimensions, less attention has been paid to the visual procedures through which ...

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

open access: yesEthology, 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 ...
