China organic-rich shale geologic features and special shale gas production issues
Journal of Rock Mechanics and Geotechnical Engineering, 2014 The depositional environment of organic-rich shale and the related tectonic evolution in China are rather different from those in North America. In China, organic-rich shale is not only deposited in marine environment, but also in non-marine environment:

4C 02.27: what is inside a double-double radio quasar? [PDF]
, 2010 Recently Jamrozy et al. (2009) identified 4C 02.27 (J0935+0204) as the first possible example of a double-double radio source which is optically identified with a quasar (i.e. not a galaxy), at the redshift of z=0.649.

The Ability of Significant Tidal Stress to Initiate Plate Tectonics [PDF]
, 2019 Plate tectonics is a geophysical process currently unique to Earth, has an important role in regulating the Earth's climate, and may be better understood by identifying rocky planets outside our solar system with tectonic activity.

Exploring and Summarizing Ensemble Solutions to Geophysical Inverse Problems
Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.Abstract Posterior sampling algorithms have been applied to many geophysical inverse problems, including electrical resistivity sounding, seismic tomography, and gravity and geodetic inversions. Unlike optimization‐based approaches that yield a single best‐fit solution, these algorithms produce an ensemble of solutions that sample the posterior ...
