series recordings for identification of such stability mechanisms in open systems,
building upon the initial work of [29, 30].
In conclusion, we have studied oscillatory systems that are explicitly driven by
time-variable external influences; such models aim at explicitly taking into account
the thermodynamic openness that is crucial for living systems to stay alive. Modelling
this openness deterministically and explicitly may be key to advancing our understanding of the underlying mechanisms at play in the stability of living systems, such
as the brain [6], and even beyond, e.g. in cosmology [36].
