Query: Coupling from the past for exponentially ergodic one-dimensional
  probabilistic cellular automata   We prove that, for every one-dimendional exponentially ergodic probabilistic
cellular automaton with positive rates, there exists a locally defined
coupling-from-the-past flow whose coalescence time has a finite exponential
moment.
