With an increase in China's oil imports, China's oil supply will also continue to be effected by the socio-economic stability of oil-exporting countries and the safety of oil transport routes. This paper introduces a systematic and quantitative method to evaluate the influence of China's oil...

Considering that memory and conformity could affect the agent’s decision, in this paper, we propose a novel model to describe the vaccination dilemma by entangling the spreading dynamics with an evolutionary framework. Our results indicate that if the individuals make decision mostly depending...

A universal bipartite model is proposed based on an energy supply–demand network. The analytical expression of SPL distribution of the node weight, the “shifting coefficient” α and the scaling exponent γ are presented without edge weight growth by using the mean-field theory approach....

Purpose: This paper aims to study the oscillation phenomenon before chaos as well as its mechanism of occurrence in the energy-saving and emission-reduction system. Design/methodology/approach: The system dynamics analysis, phase portrait analyses, equilibrium point analysis and bifurcation...

This paper proposed a pretreatment technique for waste activated sludge (WAS) anaerobic fermentation by employing environmentally-friendly ferrous-activated-sulfite to advance the production of short-chain fatty acids (SCFAs). Experimental analysis illustrated that maximal SCFAs yield ascended...
