In this research, we take into account the functional variety, topological complexity, and disturbance randomness of UDSs and define a new formula of resilience based on three parts of system severity, i.e. social severity affected by urban flooding, environmental severity caused by sewer overflow, and technological severity considering the safe operation of downstream facilities.
Many co-expression patterns are conserved across species, suggesting the patterns are under selection pressure and therefore functional; a variety of studies have confirmed this premise [ 3- 7].
