Quantitative Mineral Resource Assessment of Lithium Pegmatite Deposits in the Southern Appalachian OrogenNARA Subscribed
The first quantitative mineral resource assessment for undiscovered lithium pegmatite deposits in the southern Appalachian region of the United States was conducted. Permissive tracts for lithium pegmatite deposits were delineated by integrating lithological, tectonic, geochemical, geophysical and mineral occurrence data. Lithium pegmatite prospectivity of the tracts was ranked with simplified mappable criteria, including prox...
Molecular phylogeny of rare arboreal rats from SE Asia, genera Pithecheir and PithecheiropsNARA Subscribed
Rodents, particularly the family Muridae, are exceptionally species-rich, with a global distribution and significant ecological and economic roles. Despite their ubiquity, many murids remain poorly studied, especially members of the subfamily Murinae inhabiting Southeast Asia’s biodiverse island ecosystems. Borneo, a hotspot for arboreal rodent diversity, hosts several endemic murines, including the elusive Emmons’s tree rat (...
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...
Precipitation variability interacts with mean precipitation to restructure a semiarid grassland communityNARA Subscribed
Climate forecasts project change not only in the mean of climate variables but also in their variance. If these dual changes interact, then future ecological dynamics will be difficult to predict using current experimental approaches, which typically change the mean or impose a single extreme event, such as drought. We designed a new field experiment to factorially reduce mean precipitation and increase its interannual variabi...
We announce the U.S. Geological Survey (USGS) Rotating X-ray Computed Tomography (RXCT) Coral-Core Archive, a digital resource derived from ~360 coral reef cores curated at the USGS Pacific and St. Petersburg Coastal and Marine Science Centers. The archive delivers calibrated 3-dimensional image volumes that enable reproducible values of skeletal density, linear extension, and calcification from decadal- to centennial-scale re...
Navigating Through the Noise: A Roadmap for Combining Interdisciplinary High Dimensional Data in Biological SystemsNARA Subscribed
The explosion of different “omic” technologies and methods has led to many advances in ecology, evolution, and developmental biology, identifying countless novel phenotypes and molecular variants of interest as well as establishing new biological principals. The logical next step is to integrate these methods to deepen our understanding of these phenotypes and uncover biologically meaningful relationships, yet the pace of this...
