Erbium-YAG laser therapy – analysis of more than 1,200 treatments

Background: Ablative laser treatment is widely used in dermatology. Different laser types are available. In contrast to that, the medical publication on erbium-YAG laser in dermatology often include small samples only. Objective: We want to demonstrate the versatility of classical erbium-YAG laser for medical conditions in dermatology in a single-center study. Materials and methods: This is a r...

Switching with more than two colours

The operation of switching a finite graph was introduced by Seidel, in the study of strongly regular graphs. We may conveniently regard a graph as being a 2-colouring of a complete graph; then the extension to switching of an m-coloured complete graph is easy to define. However, the situation is very different. For m > 2, all m-coloured graphs lie in the same switching class. However, there are...

Turbulence in more than two and less than three dimensions.

We investigate the behavior of turbulent systems in geometries with one compactified dimension. A novel phenomenological scenario dominated by the splitting of the turbulent cascade emerges both from the theoretical analysis of passive scalar turbulence and from direct numerical simulations of Navier-Stokes turbulence.
