The striation pattern of heat loads on the divertor targets is determined by the plasma response to external resonant magnetic perturbations (RMPs) applied for suppression of edge localized modes (ELMs). Ideal and kinetic plasma response analysis wit

In the last experimental campaign (OP1.2b) of the stellarator Wendelstein 7-X (W7-X), boronisation as a mean for first wall conditioning was applied for the first time which led to strongly reduced impurity fluxes from plasma-facing components. Therm

Data on the distributed dynamics of water table elevation (WTE) and on the variation of water discharge are needed for calculation of the carbon balances of entire mire complexes. Here we describe the development of a high-resolution transient hydrol

As a tradeoff between efficiency and costs mbox{modern} communication systems contain a variety of components that can at least be considered weakly nonlinear. A critical element in evaluating the degree of nonlinearity of any underlying nonlinear sy
