Parameter that can induce the change of Hcp and Mcp (I, heuristic approach I; II, heuristic approach II; see text).
Fold change of the parameters. Change of all parameters but two parameters (Ka, KfNcp) are increase.
Hcp fell down to less than a fourth of the oscillating one; Mcp increased to more than one-third of the differentiated one.
Input Delta is constant (“C”) or pulsating (“P,” period is 124 min).
