A depth-dependent constitutive framework for stratified non-newtonian flows: beyond homogeneous Herschel–Bulkley rheologyNARA Subscribed
Geophysical mass flows such as mudflows and lahars commonly exhibit vertical heterogeneity, often inferred from observed concentration gradients associated with particle settling, consolidation, and fines migration. Standard Herschel–Bulkley (HB) rheology assumes spatially uniform material parameters and therefore cannot explicitly represent depth-dependent rheological structure. This work introduces a depth-dependent constitu...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Fungal diversity in Atlantic oak root systems: a pioneering study in the Cantabrian MountainsNARA Subscribed
Oak forests are native ecosystems that support diverse life forms and provide essential services. This study focused on elucidating the taxonomic characterization and diversity of fungal species in Atlantic oak woodlands dominated by Quercus petraea at its southwestern distribution limit in the Iberian Peninsula. Sampling was conducted in three protected natural areas to assess fungal root diversity by macroscopic and microsco...
Cortical volumetry and longitudinal cognitive changes in Parkinson’s disease: insights from the COPPADIS cohortNARA Subscribed
Cognitive decline is a major non-motor symptom in Parkinson’s disease (PD), often linked to brain atrophy. This study examines the relationship between cortical atrophy and age groups in predicting cognitive decline in PD over five years. 188 PD patients from the COPPADIS cohort were stratified by age: young (30–55 years, N = 47), middle-aged (56–65 years, N = 59), and older adults (66–75 years, N = 82). Baseline cortical volu...
Dietary vitamin D intake and 2-year changes in cognitive function in older adults with overweight or obesity and metabolic syndromeNARA Subscribed
The protective role of dietary vitamin D intake on cognitive function is of interest, but evidence remains inconsistent. We aimed to evaluate the association between dietary vitamin D intake and 2-year cognitive changes in older adults at risk of cognitive decline. This longitudinal study comprised 5454 individuals (aged 55–75 years in men and 60–75 years in women) who exhibited overweight/obesity and metabolic syndrome. Data...
SNAPSHOT USA 2019–2023: The First Five Years of Data From a Coordinated Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multicontributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of specie...
