This model generates the results inFigure 1&4. Notably, the contribution of push feedback varies with19 the parameters. Fig. S2 are the cases where the contribution of20 push feedback isminor. Thus, the role of feedback is very important.27 Actually, we are now working on applying the push-pull feedback to practical applications and have obtained en-45 couraging preliminary results. Here, we introduce the basic idea.
