Cover image by Peng Xu on pages 182-196. The image illustrates the microstructure of multi-phase rocks, wherein interconnected pore networks and mineral grains collectively govern fluid transport behavior. The water phase highlights coupling between pore geometry and multiphase flow. The multi-gate mixture-of-different-experts model integrates features to simultaneously predict key petrophysical properties. The model improves accuracy while maintaining physical consistency, providing a robust tool for multi-phase rock characterization with implications for the geological energy sector.
