In-season optical sensor-based variable-rate nitrogen management in maize production: a meta-analysisNARA Subscribed
Purpose In-season optical sensor-based variable-rate nitrogen application (VRA) is designed to optimize nitrogen (N) management in maize (Zea mays L.) by aligning N inputs with real-time crop demand, yet reports on its performance are inconsistent. This study quantified the effects of VRA relative to fixed-rate management on N inputs, yield, N use efficiency, and profit; assessed VRA’s economic response to market volatility; i...
Targeting Mitochondrial Dysfunction in Acute Organophosphate Toxicity: A Preliminary Evaluation of Cyclosporine ANARA Subscribed
Background Organophosphate (OP) compounds are widely used agricultural chemicals that pose significant public health and chemical threat concerns due to their neurotoxic effects. Although OP toxicity has classically been attributed to acetylcholinesterase inhibition and cholinergic crisis, emerging evidence suggests mitochondrial dysfunction may represent an additional and clinically relevant mechanism of injury. Experimental...
Morphological evolution of the 2021 Tajogaite cone (Cumbre Vieja, La Palma, Spain) between January 2022 and July 2024NARA Subscribed
Volcanic eruptions shape the landscape. While some events may locally cause mass loss (e.g. gravitational failure, explosive excavation, or collapse following magma withdrawal), constructive processes are dominant: volcanic deposits create new land, cover the landscape, and build new cones around vents. The 2021 Tajogaite eruption (La Palma, Spain) produced a cinder cone complex that was initially 187 m taller than the pre-eru...
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...
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...
Potential Ecological Risk Index and Metal Fate in a Karstic Tropical Lagoon: Chelem, Yucatan, MexicoNARA Subscribed
Chelem is a karstic lagoon with urban settlements, economic activities, and environmental services, making it highly vulnerable to metal contamination. This study evaluated metal sediment contamination using enrichment factor, geoaccumulation index and ecological risk index across dry, rainy and Nortes seasons. Cadmium and arsenic concentrations exceed the SQuiRTs thresholds for early biota damage. Metal distribution was drive...
