The Black Array of Broadband Absolute Radiometers Earth Radiation Imager (BABAR-ERI) is a small, adaptable nadir-pointed pushbroom imager to measure Earth-leaving broadband radiance from 0.3 µm to 100 µm with higher information content than is currently measured by reducing radiometric uncertainty and enabling cloud-resolving spatial resolution. The three-instrument BABAR-ERI suite fits a 12U CubeSat form factor and contains c...
Hypothalamus Amyloid Levels Are Associated with Early Sex-Dependent Alterations in Peripheral Energy Homeostasis in TgF344-AD RatsNARA Subscribed
We reported previously that diet-induced obesity exacerbates early-stage Alzheimer’s disease (AD)–like pathology in TgF344-AD rats. Those findings also suggested that they may be prone to weight gain during early AD development, raising the possibility of early hypothalamic dysfunction. In this study, we investigate this by determining whether hypothalamic soluble amyloid-β 40 (Aβ 40 ) and amyloid-β 42 (Aβ 42 ) are detectable...
The Toxicology Investigators Consortium 2024 Annual ReportNARA Subscribed
In late June 2021, multiple days of record‐breaking heat caused an unprecedented amount of foliage death in the forests of the Pacific Northwest, USA. Portions of tree canopies with healthy green foliage prior to the heat changed to red or orange shortly after the event. The change in foliage color could be readily seen in satellite imagery and was corroborated as foliar death (heat scorch) by aerial surveys and extensive obse...
Naturally derived, fine-grained olivine ceramics were synthesized by an evacuated hot-pressing method that yielded samples with porosities of < 0.1%, a marked reduction compared to samples fabricated by conventional hot pressing with porosities of ≳1%. Evacuated hot pressing yields bright-green olivine samples that are transparent at the mm-scale, resembling the appearance of the single crystals from which they were synthesize...
Optimising Instrumented Mouthguard Data Analysis: Video Synchronisation Using a Cross-correlation ApproachNARA Subscribed
Purpose Head acceleration events (HAEs) are a growing concern in contact sports, prompting two rugby governing bodies to mandate instrumented mouthguards (iMGs). This has resulted in an influx of data imposing financial and time constraints. This study presents two computational methods that leverage a dataset of video-coded match events: cross-correlation synchronisation aligns iMG data to a video recording, by providing play...
Ontogenetic change in body shape for white sharks, Carcharodon carcharias , in Australian watersNARA Subscribed
The analysis of how biological shape changes across ontogeny can provide us with valuable information on how species adapt behaviorally, physiologically, and ecologically. The white shark Carcharodon carcharias is one of the largest and most widely distributed apex predators globally, yet an understanding of ontogenetic changes in body shape and relative scaling of length and weight measures is limited, especially in relation...
