Human hypoxia models in aerospace medicine: Potential applications for human pharmacological research

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aerospace medicine required controlled terrestrial models to investigate influences of altered atmosphere conditions, such as hypoxia, on human health and performance. These models could potentially be expanded to encompass disease conditions or treatment targets regulated through hypoxia or hypercapnia.

Physically Based Real‐Time Rendering of Eclipses

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present a novel approach for simulating eclipses, incorporating effects of light scattering and refraction in the occluder's atmosphere. Our approach not only simulates the eclipse shadow, but also allows for watching the Sun being eclipsed by the occluder.

Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog

open access: yesComputer Graphics Forum, EarlyView.
Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

Synthesis of hafnium carbide (HfC) via one‐step selective laser reaction pyrolysis from liquid polymer precursor

open access: yesJournal of the American Ceramic Society, EarlyView.
➢ A one‐step selective laser reaction pyrolysis (SLRP) technique was developed to rapidly synthesize hafnium carbide (HfC) from liquid polymer precursors. ➢ XRD and TEM confirmed the nanocrystalline structure of the HfC. ➢ The SLRP‐based process achieved up to 54% ceramic yield, 18% higher than furnace‐based methods.

Religious Ethics and AI: Introduction to the Focus Issue

open access: yesJournal of Religious Ethics, EarlyView.
ABSTRACT Does religious ethics have anything meaningful to say about the many difficult metaphysical, ethical, and theological questions surrounding artificial intelligence (AI)? The four articles featured in this Focus Issue suggest that it does. Mariele Courtois's essay focuses on the cultivation of prudence as a necessary virtue for the moral life ...

Insights on the volcanic and impact histories of the lunar nearside from the petrology, geochemistry, and geochronology of the Calcalong Creek lunar regolith breccia meteorite

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 392-421, March 2025.
Abstract The Calcalong Creek lunar meteorite is a regolith breccia with a lithologically diverse array of clasts set in a glassy, highly vesicular matrix. Here, we present a comprehensive new analysis of the meteorite. Comparisons to remote sensing data, lunar sample lithologies, and lunar sample ages indicate that it was likely sourced from regolith ...
