Comprehensive Validation of Novel Deep Learning Architectures to Forecast Geomagnetic Substorms

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Magnetic substorms are disturbances in the terrestrial magnetosphere that can have significant space weather impacts, although forecasting their onset accurately remains an open problem. In this study, we develop multiple novel machine learning architectures based on convolutional neural networks, long short‐term memory networks, extreme ...

Downscaling Daily Discharge to Sub‐Daily Scales for Alpine Glacierized Catchments

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Hydrological dynamics in glacierized catchments of the Alps are shaped by temperature‐driven processes, including snow and ice melt as well as precipitation, leading to diel streamflow cycles that vary in intensity within‐ and among‐the seasons.

Benchmarking speech biomarkers of Alzheimer's against cognitive and neural measures

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Digital speech biomarkers (DSBs) support the detection and monitoring of Alzheimer's disease (AD) in Latinos. However, they have not been benchmarked against standard cognitive and neuroimaging measures, missing a critical validation milestone. METHODS Thirty‐three AD patients and 33 healthy controls completed verbal fluency tasks,

Why Size Does Not Matter: Sex Driven Home Range Differences in Brown Bears

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This is a novel anlaysis of unique dataset never find anywhere more than 60 collared free ranging brown bears movement data. ABSTRACT Sex, body size and environmental conditions are key determinants of home range size in large mammals, yet their relative importance within populations remains unclear for many wide‐ranging carnivores such as brown bears.

Rapid Evolution of Super Equatorial Plasma Bubbles and X‐Pattern EIA Formation During Extreme Storm Conditions on 12 November 2025

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Extreme conditions during storms profoundly alter the evolution of equatorial plasma bubbles (EPBs), yet the key dynamics remains poorly understood. We document the rapid expansion, contraction, and decay of super EPBs in South America during the 12 November 2025 storm with Interplanetary Magnetic Field (IMF) Bz/By magnitude exceeding ∼50 nT ...

Integrated Evaluation of Contaminant Profiles, Detection Techniques, and Management Strategies for Tannery Sludge

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT This review article critically examines the environmental and health hazards of tannery sludge (TS), a complex by‐product of the leather tanning industry. TS is characterized by a diverse array of contaminants, including heavy metals like chromium, organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds ...
