Strongly pagophilic, the Adélie penguin Pygoscelis adeliae has long been designated a sea ice obligate species, which included the requirement to find pack ice on which to molt. However, observations have accumulated over the years to question this attribute; therefore, we investigated this aspect of the species’ natural history strategy through a synthesis of published, unpublished, and historical records obtained Antarctic-w...
Biomimetic Constructs for Achilles Tendon Regeneration and their Translation to Human MedicineNARA Subscribed
Background: Achilles tendon injuries are among the most common lower-body tendon injuries, often resulting fromoveruse and repetitive motion. Current treatments, ranging from conservative therapies to biological grafts, have drawbacks, including limited regenerative capacity and the risk of graft rejection. To overcome these challenges, tissue engineering shows growing promise for Achilles tendon regeneration, with ongoing res...
Although plasma pTau181 has been shown to accurately discriminate patients with Alzheimer’s disease from healthy older adults, there are few studies of plasma biomarkers among middle-aged populations. Given the potential utility of plasma AD biomarkers such as pTau181 in screening for disease risk, examining pTau181 in a middle-aged cohort without AD is important for future implementation. The objectives of this study were to...
Identification of homogeneous rainfall regions in the São Francisco River Basin, Brazil, through cluster analysisNARA Subscribed
Precipitation is the primary source of water in a river basin and plays a key role in water resource management by affecting water availability. However, large river basins like the São Francisco River Basin in Brazil show significant variability in rainfall patterns, leading to different water supply levels across sub-regions. To identify areas with similar rainfall patterns, the k-means clustering method was used on rainfall...
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...
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...
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...
