“…In particular, long-term integration was addressed by Gerritsma et al [10], Heuveline, Schick and Song [19,34,36], Wilkins [38], Özen nad Bal [29,30], and most recently by Esquivel et al [9], among others. Methods for flows exhibiting uncertain periodic dynamics were proposed, e.g., by Bonnaire et al [2], Lacour et al [22] and Schick et al [33]. These methods typically entail time-dependent or other variants of gPC expansions that are tailored to the changing character of the solution.…”
