Apart from some misunderstandings of this summer, recent developments have led to considerable progress in this controversial but challenging eld. Intermittency is now established as an eeect in at least two dimensions, where it has turned out to be stronger and cleaner than in one. The eeect is strongest in e + e ? collisions at LEP energies. At these energies parton showering has become a goo...

Recently, the fluctuation-spectrum theory has been developed in order to characterize the fluctuation of stochastic time series [ 11. Some scaling properties of fluctuation spectra have been found near the intermittent transition point [2]. In experiment Fukushima et al. also showed scaling laws for an intermittency in a coupled chaos system [ 3 1. It is important to investigate the scaling pro...

We consider the turbulent energy dissipation from one-dimensional records in experiments using air and gaseous helium at cryogenic temperatures, and obtain the intermittency exponent via the two-point correlation function of the energy dissipation. The air data are obtained in a number of flows in a wind tunnel and the atmospheric boundary layer at a height of about 35 m above the ground. The h...

The role of Bose-Einstein correlations in a widely discussed intermittency phenomenon is reviewed. In particular, it is shown that particle correlations of different origin are better displayed when analysed as functions of appropriately chosen variables. Correspondingly, if the shape of Bose-Einstein contribution is chosen to be Gaussian in 3momentum transferred, it provides the power-like law...

We study a mathematical model for the dynamics of patterned dryland vegetation in the presence of rainfall intermittency, adopting a spatially explicit approach. We find that most results found for constant precipitation carry over to the case of intermittent rainfall, with a few important novelties. For intermittent precipitation, the functional forms of the water uptake and consequently of th...

The phenomenon of intermittency has been widely discussed in physics literature. This paper provides a model of intermittency based on Lévy driven Ornstein-Uhlenbeck (OU) type processes. Discrete superpositions of these processes can be constructed to incorporate non-Gaussian marginal distributions and long or short range dependence. While the partial sums of finite superpositions of OU type pr...

In this Letter, an electrical circuit is built for realizing the multi-state intermittency generated by a simple force-driven chaotic system. The intermittency phenomenon and its underlaying mechanism are analyzed, and the experimental results are discussed. It is shown that, with two classes of invariant subspaces, the number of the laminar states and the distance between the adjacent laminar ...

Event-by-event intermittency analysis of Toy Monte Carlo events is performed in the scenario high multiplicity as case at recent colliders RHIC and LHC for AA collisions. A power law behaviour Normalized Factorial Moments (NFM), F_{q} Fq function number bin...

Consideration is given to methods for the evaluation of surface wear from fretted electrical contact surfaces. The surfaces under consideration are selected for in-vivo applications, they are testing using purpose built fretting apparatus to investigate intermittency. The intermittency is associated with high frequency transients in the contact resistance between the two interfaces. These event...

A three-wave model of auroral radio emissions near the electron plasma frequency was proposed by Chian et al. (1994) involving resonant interactions of Langmuir, whistler and Alfvén waves. Chaos can occur in the nonlinear evolution of this three-wave process in the magnetosphere. In particular, two types of intermittency, due to either local or global bifurcations, can be observed. We analyze t...
