Hopfield Neural Networks for Online Constrained Parameter Estimation With Time‐Varying Dynamics and Disturbances

International Journal of Adaptive Control and Signal Processing, Volume 40, Issue 3, Page 544-564, March 2026.
This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Does the Cave Environment Limit Functional Diversity? Rethinking Patterns in Oniscidea Assemblages From a Neotropical Karst

Biotropica, Volume 58, Issue 1, January 2026.
Cave habitats strongly filter functional traits, constraining the diversity of terrestrial isopod communities along the epigean–hypogean gradient. Functional turnover decreases while richness differences increase in hypogean systems, reflecting uneven occupation of trait space rather than simple trait replacement.

Fungal Species of Botryosphaeriaceae Associated With Avocado Dieback in Southern Spain

Plant Pathology, Volume 75, Issue 1, January/February 2026.
In southern Spain, water scarcity has favoured avocado diseases, causing branch dieback, mummified fruits and cankers. Between 2019 and 2022, 252 fungi were isolated; the most common were Neofusicoccum spp. and Lasiodiplodia sp. Their pathogenic role was confirmed, with Botryosphaeriaceae identified as the main cause of avocado dieback.

Revisiting the taxonomy and nomenclature of Phyla, a small genus of Verbenaceae

Nordic Journal of Botany, Volume 2025, Issue 12, December 2025.
Phyla is unique within Verbenaceae due to the presence of malpighiaceous hairs. Its taxonomy has long been marked by difficulties in defining species boundaries. The most recent revision of the genus recognized five species and three varieties. In this study, however, we recognize only two species and no varieties: P.

Feminización de personajes masculinos en dos montajes contemporáneos de tragedias griegas: el Prometeo de Carme Portaceli y el Creonte de Miguel del Arco

Cuadernos de Filología Clásica. Estudios griegos e indoeuropeos, 2023
En la Antigüedad clásica, donde el teatro era un ámbito masculino, se producía un desdoblamiento de género: un dramaturgo varón escribía un personaje femenino, con un discurso convencionalizado para reflejar, desde una perspectiva masculina, la idea de la feminidad imperante en la sociedad. Dicho personaje era luego interpretado por un actor varón, que

Almost Seven Decades of Coastal Bird Community Recovery Across Three European Seas

Global Change Biology, Volume 31, Issue 11, November 2025.
Our study examined long‐term trends in coastal bird communities across three European seas from 1957 to 2024. We found that bird abundance and diversity have increased over time, although these improvements vary among regions and sites. Protected areas—particularly strictly protected ones—play an important role in supporting these recoveries, but ...

Role of the Endogenous Cannabinoid System in the Regulation of Motor Activity

Neurobiology of Disease, 1998
One of the prominent pharmacological features of drugs acting at the brain cannabinoid receptor (CB1) is the induction of alterations in motor behavior. Catalepsy, immobility, ataxia, or the impairment of complex behavioral acts are observed after acute ...
