The steeper the slope of $c_i(t)$ around the threshold +crossings, the less $T_1$ changes with scale variations. +In a sense, $f_i(t)$ resembles a duty +cycle of some sort, as it quantifies purely temporal relations in the structure +of $c_i(t)$ with no regard for precise amplitude values apart from their +relation to $\thr$. This near-complete loss of amplitude information is the key +to the intensity invariance of $f_i(t)$: For a given $\thr$, different scales +of $c_i(t)$ can still result in similar $T_1$ segments depending on the +magnitude of the derivative of $c_i(t)$ in temporal proximity to time points at +which $c_i(t)$ crosses $\thr$.
