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...
Clinician Perspectives on the Implementation of a Web-Based Tool to Support Shared Decision-Making for Mid-Adult HPV VaccinationNARA Subscribed
In 2019, the U.S. Advisory Committee on Immunization Practices recommended shared clinical decision-making (SCDM) for HPV vaccination among unvaccinated adults aged 27–45 years (i.e., mid-adult). However, the implementation of this recommendation is challenging. This study assessed a decision tool, HPV Decide, designed to facilitate SCDM for mid-adult HPV vaccination. We used exploratory sequential mixed methods to gather stak...
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...
Predicting the progression of MCI and Alzheimer’s disease on structural brain integrity and other features with machine learningNARA Subscribed
Machine learning (ML) on structural MRI data shows high potential for classifying Alzheimer’s disease (AD) progression, but the specific contribution of brain regions, demographics, and proteinopathy remains unclear. Using Alzheimer’s Disease Neuroimaging Initiative (ADNI) data, we applied an extreme gradient-boosting algorithm and SHAP (SHapley Additive exPlanations) values to classify cognitively normal (CN) older adults, th...
Unravelling Changes in the Pinus radiata Root and Soil Microbiomes as a Function of AridityNARA Subscribed
Increased aridity is emerging as a key impact of climate change in terrestrial ecosystems globally. Forest biomes are particularly vulnerable to the impacts of changing environmental conditions due to their long‐lived and sessile nature. Microbiomes have coevolved with plants under changing environmental conditions with shared fitness outcomes. However, both the movement of plants via domestication and rapid pace of environmen...
The importance of forests for sequestering carbon has created widespread interest among land managers for identifying actions that maintain or enhance carbon storage in forests. Managing for forest carbon under changing climatic conditions underscores a need for resources that help identify adaptation actions that align with carbon management. We developed the Forest Carbon Management Menu to help translate broad carbon manage...

The 8.2‐ka BP event in north‐eastern North America: first combined oxygen and hydrogen isotopic data from peat in NewfoundlandNARA Subscribed
Finding direct evidence for atmospheric circulation change in terrestrial records of Holocene climate variability remains a fundamental challenge. Here we present the first combined stable oxygen and hydrogen isotopic palaeorecord from a peatland core in Newfoundland, Canada. Sphagnum cellulose samples were isolated from a core from Nordan's Pond Bog, Newfoundland, and analysed for δD values. Combined with existing δ 18 O data...
Peat archives offer a diverse range of physical and chemical proxies from which it is possible to study past environmental and ecological changes. Direct numerical calibration and verification is difficult so process‐based and mechanistic studies are therefore required to establish and quantify links between environmental changes and their associated proxy‐responses. Traditional ‘space‐for‐time’ calibrations provide a solution...
Testate amoebae as a proxy for reconstructing Holocene water table dynamics in southern Patagonian peat bogsNARA Subscribed
Testate amoebae are abundant and diverse in Sphagnum peat bogs and have been used extensively as indicators of past water table depths. Although these unicellular protists are widely dispersed with globally similar hydrological preferences, regional variations in communities demand region‐specific transfer functions. Here we present the first transfer function for southern Patagonian bogs, based on 154 surface samples obtained...
