Before revision:  Here, we develop the BP approach for a particular bipartite Boolean network , composed of logic OR and AND gates, which is motivated to understand the avalanche dynamics in metabolic networks .
After revision:  Here, motivated by a need to understand avalanche dynamics in metabolic networks, we extend the BP approach for a particular bipartite Boolean network , composed of logic OR and AND gates, which is motivated to understand the avalanche dynamics in metabolic networks .
