In fully developed turbulence, intermittency is classically characterized by ζE(q), the Eulerian scaling exponent of … intermittency of the velocity of a particle advected by a turbulent intermittent field. An interesting question is then to know how … to relate the scaling functions and explore the links between ζL(q) and ζE(q). We first provide different transformations …

The purpose of the present paper is to determine the probabilistic limit behaviour of the (multi …)power variations of Y, as a basis for studying properties of the intermittency process. Notably the processes Y are in general not of …

We consider symbolic sequences of copepod behavior, classified as “break” and “slow swimming” states. Successive residence times for each state have been recorded for 327 symbolic times series obtained from 52 different trajectories. We performed a symbolic dynamics analysis of the...

The two-dimensional motion behaviour of the common intertidal gastropod Littorina littorea is investigated as a function of the immersion time from three sampling sites on an exposed rocky shore. A total of 90 individuals have been individually marked and tracked over 14 consecutive daylight low...
