A new polar motion prediction method combined with the difference between polar motion series
Geodesy and Geodynamics, 2022 After the first Earth Orientation Parameters Prediction Comparison Campaign (1st EOP PCC), the traditional method using least-squares extrapolation and autoregressive (LS + AR) models was considered as one of the polar motion prediction methods with ...

Controlled motion of polar vortex boundary in oxide heterostructures [PDF]
Nature CommunicationsPolar vortices in ferroelectric heterostructures hold promise for high-density, energy-efficient nanoelectronics, but their controlled motion remains elusive due to strong pinning and lattice-coupled dynamics.

Climate‐Induced Polar Motion: 1900–2100
Geophysical Research LettersIt has been demonstrated that the motion of the Earth's rotational pole with respect to the crust—termed polar motion—is increasingly influenced by barystatic processes, that is, continental‐ocean mass redistribution due to melting of polar ice sheets ...

Kimura’s contributions on Earth polar motion studies [PDF]
Proceedings of the Japan Academy. Series B, Physical and Biological SciencesKimura’s discovery of z-term in the polar motion (Astron. J. 22, 107 (1902) and Astron. Nachr. 158, 233 (1902)) was recognized as an epoch-making scientific achievement for modern Japan, opening its doors to the world in 1868.

Analysis and prediction of polar motion using MSSA method
Earth, Planets and Space, 2021 Polar motion is the movement of the Earth's rotational axis relative to its crust, reflecting the influence of the material exchange and mass redistribution of each layer of the Earth on the Earth's rotation axis. To better analyze the temporally varying

Short periodic variations of polar motion and hemispheric atmospheric angular momentum excitation functions in the period 1984-1992 [PDF]
Annales Geophysicae, 1995 Short periodic oscillations with the periods from 10 up to 110 days of the hemispheric components of effective atmospheric angular momentum (EAAM) excitation function and their correlation with polar motion excitation function have been analyzed.
