The recently proposed discrete scale invariance and its associated log-periodicity are an elaboration of the concept of scale invariance in which the system is scale invariant only under powers of specific values of the magnification factor. We report on the discovery of a novel mechanism for such log-periodicity relying solely on the manipulation of data. This “synthetic” scenario for log-periodicity relies on two steps: (1) the fact that approximately logarithmic sampling in time corresponds… CONTINUE READING
