Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Hydrothermal co-enrichment of Au, As, Co, and Cu in orogenic deposits: insights from the Pohjanmaa beltNARA Subscribed
The Huhta Au and Jouhineva Au-Co-Cu-Ag deposits lie ~ 3 km apart in the Pohjanmaa Belt, western Finland, in Paleoproterozoic metavolcano-sedimentary host rocks. Both deposits are spatially and genetically related to the Sievi shear zone but have different metal endowments. The main regional structural grain is characterized by D 2 -D 3 fold interference and NW-SE to NNW-SSE-trending D 3 shear zones. Huhta hosts auriferous D 3...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Highly Dynamic Archaeal and Bacterial Communities From the Surface to the Deep in the Atlantic OceanNARA Subscribed
Though archaea are ubiquitous in the oceans, at times present in quantities equal to bacteria, in general, archaea are underreported when compared with bacteria, and little is known about archaeal connectivity in the ocean. Here, we present the first time series data of size‐fractionated archaea with temporal resolution of days across a depth transect in the oligotrophic Atlantic Ocean. Archaeal communities were variable from...
Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group‐level processes such as subgroup formation and fission–fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing coh...
This systematic review examines the prevalence, underlying mechanisms, cohort characteristics, evaluation criteria, and cohort types in white matter hyperintensity (WMH) pipeline and implementation literature spanning the last two decades. Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, we categorized WMH segmentation tools based on their methodologies from January 1, 2000, to...
