The ageing behaviour is not necessarily of linear nature and can form non-linear ageing trajectories. This non-linear behaviour translates to a S O H dependency of the degradation rate, which has to be considered as another degradation rate influence additional to the stress factors. Hence, depending on the actual S O H, the cell''s loss of S O H (Δ S O H) …
