The Oxygen Isotope Identity of the Earth and Moon with Implications for the Formation of the Moon and Source of Volatiles Academic Background The isotopic similarity between Earth and Moon rocks has long been a significant puzzle in geochemistry and cosmochemistry, contradicting prevailing models of Moon formation, particularly the “Giant Impact Th...

Exploring, Sampling, and Interpreting Lunar Volatiles in Polar Cold Traps Academic Background The permanently shadowed regions (PSRs) at the lunar poles, along with other surface volatile deposits, are critical sampling targets for future human missions to the Moon. These volatiles hold significant scientific value and could potentially shift strat...

# Basis Restricted Elastic Shape Analysis on the Space of Unregistered Surfaces ## Introduction Analyzing three-dimensional (3D) surfaces has become increasingly important in computer vision, driven by the emergence of high-accuracy 3D scanning devices. These devices have significantly increased the availability of 3D data, enabling applications in...

Controlling the Spectral Persistence of a Random Laser Research Background Since their theoretical proposal by Letokhov in the 1960s, Random Lasers (hereinafter referred to as RLs) have gradually become a widely researched field. A significant feature of RLs is that they do not require precisely manufactured optical cavities, which gives them consi...
