Copyright in the age of artificial intelligence: Navigating access to algorithmic training materials and the three‐step test for text and data mining in Nigeria

The Journal of World Intellectual Property, EarlyView.
Abstract Over the past decade, the Nigerian government has sought to leverage Artificial Intelligence (AI) to drive socio‐economic transformation and improve the welfare of its citizenry. Recent initiatives, such as the establishment of the National Centre for AI and Robotics (NCAIR) and the development of several strategic AI policies, highlight the ...

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

Meteoritics &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 ...

The solar system Fe/Mg ratio

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 529-543, March 2025.
Abstract Solar wind Fe and Mg fluences (atoms/cm2) were measured from Genesis collectors. Fe and Mg have similar first ionization potentials and solar wind Fe/Mg should equal the solar ratio. Solar wind Fe/Mg is a more valid measure of solar composition than CI chondrites and can be measured more accurately than spectroscopic photospheric abundances ...

Impact crater lake evolution and concomitant hydrothermal mineralization recorded by the Wörnitzostheim drill core at the Ries impact structure, Germany

Meteoritics &Planetary Science, Volume 60, Issue 4, Page 795-822, April 2025.
Abstract Impact‐generated hydrothermal systems and postimpact crater lake systems are well‐documented geological phenomena; however, evidence of hydrothermal venting into impact crater lake systems has rarely been reported. We investigated the well‐preserved contact between hydrothermally altered impact melt‐bearing breccia (outer/surficial suevite ...

Three‐dimensional morphological analysis of Chang'e‐5 lunar soil using deep learning‐automated segmentation on computed tomography scans

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Grain morphology is a fundamental characteristic of lunar soil that influences its mechanical properties, sintering behavior, and in situ resource utilization. However, traditional two‐dimensional imaging methods are time‐consuming and lack full three‐dimensional (3D) structural information. This study presents an automated deep learning‐based
