Formulation of testing gravitational redshift based on Laser Time link between China Space Station and a ground station
Rui Xu, Wenbin Shen, Hok Sum Fok +11
This paper presents a high-precision gravitational redshift test using the China Space Station (CSS) Laser Time Transfer (CLT) system. We develop a comprehensive observation equati…
Accelerating the Simulation of Ordinary Differential Equations Through Physics-Preserving Neural Networks
Andrew Tagg, Andrew Frandsen, Andrew Ning
Numerical simulation of ordinary differential equations (ODEs) can be challenging when the system exhibits high accelerations and rapidly changing dynamics. Under these conditions…
