Sex- and Age-Related Variation in Vertebral Geometry Influences Lumbar Spine Loading: An Image-Based Computational Modeling StudyNARA Subscribed
Purpose Low back disorders are highly prevalent and disproportionately affect women and older adults, yet the biomechanical mechanisms underlying these demographic disparities remain unclear. This study aimed to investigate how sex- and age-related anatomical differences in vertebral geometry influence lumbar spine loading patterns. Methods Three hundred sixty lumbar motion segments were derived from CT scans of 60 asymptomati...
Multi‐Decadal Dynamics of Wetland Methane Emissions Revealed by Knowledge‐Guided Machine LearningNARA Subscribed
Measurement of methane fluxes (FCH 4 ) from natural systems, such as wetlands, has lagged far behind carbon dioxide fluxes. Short and fragmented wetland FCH 4 data limit our ability to assess its long‐term dynamics and potential climate feedbacks. Extrapolating short‐term FCH 4 records to recent decades remains challenging for both process‐based models and data‐driven machine learning (ML) approaches. Here, we develop a knowle...
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...

Bridging Functions and Values: Advancing Wetland Ecosystem Service Assessment Through Use of a Service Capacity IndexNARA Subscribed
Wetland service or values are often assumed to occur at a comparable level to wetland function (i.e., higher functioning wetlands provide more services). However, services are seldom directly evaluated because of the lack of structured assessment approaches. For wetland ecosystem service to be effectively incorporated in regulatory and monitoring programs, there needs to be parsimonious assessment tools that can be applied sys...
Drought Reduces Formation, but Enhances Persistence, of Mineral‐Associated Organic Matter in a Grassland SoilNARA Subscribed
Drought effects are pervasive in terrestrial ecosystems, yet there is limited understanding of how drought impacts the transformation of plant carbon (C) inputs to mineral‐associated organic matter (MAOM)—the largest and slowest‐cycling pool of soil organic carbon (SOC). In a 12‐week 13 C‐CO 2 greenhouse labeling experiment, we tracked the formation of MAOM derived from the two dominant sources of plant C input to the mineral...
Larval Transport Pathways Reveal Critical Habitat and Benefits of a Marine Protected Area to FisheriesNARA Subscribed
Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish ( Sebastes spp.) collected in the Southern California Bight over the course of 16 years. Particle tracking was performed forward‐ and backward‐in‐time to investigate birth locations and dispersal patterns of rockfish larvae, respectively. Otolith...
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...
Short-term effects of Greenlandic glacial rock flour on soil physical properties and maize yieldNARA Subscribed
Greenlandic glacial rock flour (GRF) serves as a valuable source of silicate minerals for CO₂ uptake through enhanced weathering. Additionally, its physico-chemical properties may influence soil hydro-physical characteristics and may also have a separate effect on crop yields. This study evaluated the effects of GRF application at 50 and 100 t/ha, along with an unamended control, on soil water content at field capacity (FC), p...
Pedicularis furbishiae is a globally rare, hemiparasitic perennial restricted to dynamic riverbank habitats along the Wolastoq (Saint John) River in Maine, USA, and New Brunswick, Canada. The species now faces severe threats from habitat fragmentation, altered hydrology, and demographic collapse—particularly in New Brunswick, where several subpopulations have been recently extirpated and where recovery activities are being und...
