Human activities widely exhibit a power-law distribution. Considering stock trading as a typical human activity in the financial domain, the first aim of this paper is to validate whether the well-known power-law distribution can be observed in this activity. Interestingly, this paper determines...

The addition of nanoparticles to molten salt can enhance its utility as a thermal energy storage material for concentrating solar power plants. The heat transfer property of solar salt loaded with Al2O3 nanoparticle is investigated by molecular dynamics simulations. The results show that the...

Transition metal compounds are considered to be the most promising non-precious metal-based materials for hydrogen evolution reaction (HER), however metal particles are prone to agglomeration. It is challenging to achieve the ultra-dispersion of transition metal catalysts with nanostructure,...

In this paper, a fault repair and service restoration framework in response to extreme disasters is proposed from the perspective of combined data-driven and knowledge-driven. Firstly, theoretical analysis on the process of fault information acquisition is conducted and an emergency...
