  4. This paper reviews trends in GeoAI research and discusses cutting-edge advances in GeoAI and its roles in accelerating environmental and social sciences. It addresses ongoing attempts to improve the predictability of GeoAI models and recent research aimed at increasing model explainability and reproducibility to ensure trustworthy geospatial findings. The paper also provides reflections on the importance of defining the science of GeoAI in terms of its fundamental principles, theories, and methods to ensure scientific rigor, social responsibility, and lasting impacts.

  6. Small particles fall through sheared beds of larger particles in settings ranging from geophysics to industry, but the study of large-to-small size ratios R , spanning the trapping threshold R t , has been neglected. In simulations of noncohesive spheres for R < R t , the small-sphere vertical velocity v p first increases with shear rate γ ̇ as trapping time decreases, but v p then decreases as velocity fluctuations frustrate downward mobility. For R > R t ,   v p is constant at low γ ̇ , but again decreases at high γ ̇ . We model these behaviors and discuss analogies with electron transport in solids.
