Query: From the Kuramoto-Sakaguchi model to the Kuramoto-Sivashinsky equation   We derive the Kuramoto-Sivashinsky-type phase equation from the
Kuramoto-Sakaguchi-type phase model via the Ott-Antonsen-type complex amplitude
equation and demonstrate heterogeneity-induced collective-phase turbulence in
nonlocally coupled individual-phase oscillators.
