InSAR-Derived Surface-Deformation-Constrained Machine Learning for Permafrost Occurrence Probability Mapping in the Eastern Kunlun Mountains

Accurate characterization of permafrost distribution on the Qinghai–Tibet Plateau is crucial for assessing permafrost degradation under climate warming and engineering disturbances, as well as its potential implications for cold-region infrastructure stability. However, statistic...

The Adaptive Solution of High-Frequency Helmholtz Equations via Multi-Grade Deep Learning

Abstract The Helmholtz equation is fundamental for modeling wave propagation in acoustics, electromagnetics, and geophysics; however, high-frequency regimes remain notoriously difficult due to the severe numerical “pollution effect.” We propose FD-MGDL, an adaptive framework that...
