Before revision:  By coupling "Markov-chain layers" versus "network layers", we identify novel multiplexity-induced phenomena includingmultiplex imbalance (whereby the multiplex coupling of reversible Markov chains yields an irreversible one) andmultiplex convection ( whereby a stationary distribution exhibits circulating flows that involve multiple layers ).
After revision:  By coupling "Markov-chain layers" versus "network layers", we identify novel multiplexity-induced phenomena includingmultiplex imbalance (whereby the multiplex coupling of reversible Markov chains yields an irreversible one) andmultiplex convection interlayer Markov chains. One main finding is the identification of multiplex convection, whereby a stationary distribution exhibits circulating flows that involve multiple layers ).
