The Impact of the Lunar Cycle and Season on Small Mammal Communities Near a Large Metropolitan Area. [PDF]

Ecol Evol
Our study is one of the first studies to investigate the influences of the lunar cycle on African small mammals. Their abundance and composition decreased during a full moon night, which suggests a strong and universal response to increased illumination.

Inversion of thermal properties of lunar soil from penetration heat of projectile using a 2D axisymmetric model and optimized PSO algorithm

Frontiers in Materials, 2022
The thermophysical parameters of lunar soil can be inferred from the temperature field during the invasion process of reconnaissance projectile. This paper adopts a two-dimensional axisymmetric model to reconstruct the projectile invasion process.
