Decade-scale recovery of the Eyjafjallajökull ice cap, Iceland, after the 2010 summit eruptionNARA Subscribed
Several eruptions at glaciated volcanoes have been witnessed during the last two centuries. However, most studies have focused on understanding the volcanic products or the hazard implications. Less attention has been put into analyzing the long-term effects on the glaciers. The 2010 summit eruption of Eyjafjallajökull (Iceland) provides an excellent opportunity to study such impacts by investigating how individual areas of th...
Knowledge of the dietary composition of Atlantic marlins, especially for recently acknowledged species such as roundscale spearfish ( Tetrapturus georgii ), is limited, as sample access is constrained by international quotas and intermittent landing rates. A series of annual offshore recreational fishing tournaments target Atlantic blue marlin ( Makaira nigricans ), white marlin ( Kajikia albida ) and roundscale spearfish on t...
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...
Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership of scientists and practitioners called the Shorebird Science and Conservation Collec...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
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...
Aim Species distribution models (SDMs) address the whereabouts of species and are central to ecology. Deep learning (DL) is poised to further elevate the already significant role of SDMs in ecology and conservation, but the potential and limitations of this transformation are still largely unassessed. Location North America. Time Period 2009–2021. Major Taxa Studied Mammals, amphibians, reptiles, ants, and butterflies. Methods...
Purpose Antibiotic stewardship in critically ill pneumonia patients is crucial yet challenging, partly due to the limitations of noninvasive diagnostic tests. This study reports an antibiotic de-escalation pattern informed by bronchoalveolar lavage (BAL) results, incorporating quantitative cultures and multiplex PCR rapid diagnostic tests. Methods We analyzed data from SCRIPT, a single-center prospective cohort study of mechan...
