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...

To scientifically judge the structural abrupt transition characteristics of the carbon market price is an important means to comprehensively analyze its fluctuation law and effectively prevent carbon market risks. We propose a framework to identify abrupt transitions in the carbon market from...

In real world, most systems show significant clustering, and it is more practical to investigate the behaviors of clustered network. Previous studies are mostly focused on single clustered network and coupled clustered networks with dependency links. Here we study two clustered networks coupled...

Robustness of network of networks (NON) has been studied only for dependency coupling (Gao et al., 2012) and only for connectivity coupling (Leicht and Souza, arxiv:0907.0894). The case of network of networks with both interdependent and interconnected links is more complicated, and also more...
