- Notes: When the system moves from time point t − 1 to t, it is approaching the critical point
- 1. “↗” represents the increase of variables; “↘” represents the decrease of variables; “→” represents that there is no significant change in the variables;
- 2. “D” represents the DNM members; “N” represents the non-DNM members;
- 3. SDt is the average standard deviation at time point t; PCCt(in) is the average Pearson’s correlation coefficient between two nodes within the local network; PCCt(out) is the average Pearson’s correlation coefficient between a node inside the local network and a node outside
