Advances in observation and theory of interplanetary dust

地球与行星物理论评, 2021
Interplanetary dust is solid ejecta from various celestial bodies (e.g., comets and asteroids). They are ubiquitous in the solar system, and serve as one of the main constituents of the solar system.

The Eons of Chaos and Hades [PDF]

Solid Earth, 2010
We propose the <i>Chaotian Eon</i> to demarcate geologic time from the origin of the Solar System to the Moon-forming impact on Earth. This separates the solar system wide processes of planet formation from the subsequent divergent evolution ...

Transmission Expansion Planning using Binary Differential Evolution considering forecasted solar Photovoltaic generation

Energy Reports, 2023
Transmission Expansion Planning (TEP) can be essentially affected by solar Photovoltaic (PV) penetration because its generation is uncertain depending on weather and the environment at a specific time.
