Almost all regions of the oceans are heavily influenced by the effects of physical processes such as turbulence which in turn influence the distribution and ecology of organisms that occupy these regions. There is a real need for additional focus placed on the precise knowledge of both physical...

The probability distributions of several avalanche quantities of the Bak–Tang–Wiesenfeld sandpile in two dimensions display multifractal scaling. This explains why this prototype model remained extremely problematic and controversial for such a long time after its introduction. Other models,...

The influence of the1998 Russian financial crisis on the statistical properties of currencies in transition economies has been studied. Essential changes before and after crisis were discovered. All effects are essentially nonlinear and differ from the ones in advanced economies.

We describe the statistical properties of two large river systems: the Danube and the Mississippi. The properties of the two rivers are compared qualitatively to the general properties of a critical steady-state system. Specifically, we test the recent suggestion by Bramwell et al. (Europhys....
