In science:

Such an applicative relevance appears to be further justified by the historically significant work of Van der Pol and Van der Mark who used coupled oscillators discovered by them to make the first model for an artificial pacemaker.

We analyze the mechanism, describe the oscillating states, identify the pacemaker loops and explain key features of their distribution.

Their number also grows roughly exponentially with L up to a maximum at a length Lm ∼ N . In this letter we show that random excitable networks readily self-organize into a CO state following a transient phase during which one or a few loops are dynamically selected as driving (or pacemaker) loops.

DPAD) links, which then leads to identifying the pacemaker or driving loops (DL).
Self-Sustaining Oscillations in Complex Networks of Excitable Elements
During this transient phase, many pulses are propagating in an unsynchronized manner through the network, and a number of potential pacemakers are competing. A large gap between circulating pulses is therefore likely to be filled in.
