Microbial colonization and biofilm formation associated with microplastics (MPs) have recently attracted wide attention. However, little is known about the effect of MP shapes, aging states, and different exposed habitats on biofilm formation and associated microbial community characteristics....

Anerobic co-digestion of food waste (FW) and sewage sludge (SS), thermal hydrolyzed sludge (THS), or the filtrate of THS (THF) were conducted to study their methane potential. In comparison to the co-digestion of SS with FW, the methane yield increased 9.7%~69.7% in the co-digestion of THS and...

Constant factor loadings is a standard assumption in the analysis of large dimensional factor models. Yet, this assumption may be restrictive unless parameter shifts are mild. In this paper we develop a new testing procedure to detect big breaks in factor loadings at either known or unknown...
