A reliable functioning of technical infrastructure networks is essential for our modern, high-tech society. Cascading failures, i.e. chain reactions of failures of different infrastructures, are the cause of many failures of entire networks, e.g. large parts of the European power grids. Although cascading failures are usually influenced by network-wide nonlinear dynamics between the individual failures, their modelling has so far concentrated primarily on the analysis of sequences of failure events of individual infrastructures - however, the dynamics between these events have not been taken into account.
In an article now published by Nature Communications, an analysis scheme is presented which takes into account the event-based character of the chain reaction as well as the specific network dynamic influences.

We are happy to announce that the construction of our new building is almost finished. cfaed scientists from the Chair for Compiler Construction are the first ones who moved to a new office. So please note the new visiting address of the Chair.
We are happy to congratulate cfaed Research Group Leader Thorsten-Lars Schmidt, who was honored with the “Outstanding Mentor Award" of the Dresden International PhD Program (DIPP). The award is given by a PhD student committee to the outstanding mentors of the Dresden International PhD Program and the International Max Planck Research School. The committee is responsible for the nomination as well as for the assigment of ratings.

On the 26th of April, cfaed was part of the nationwide action day “Girls’ Day” and welcomed 13 participants between the ages of 10 and 13 (grades 5-7). The girls came from Dresden, the surrounding area of Dresden but also the long way from Görlitz! In terms of content, we demonstrated the whole range of cfaed, from basic research to applications, on the basis of such well experiencable examples as "The World of Colors" by Eleonore-Trefftz Visiting Professor Dr. Selina Olthof (Physics) and cfaed PhD student Luisa Sonntag (Chemistry), or with the lecture of doctoral student Nick Schwarzenberg (electrical engineering) "What's in the iPhone?".

Press release from TU Dresden (B CUBE - Center for Molecular Bioengineering) and Julius-Maximilians-Universität WürzburgPhysicists from Dresden and Würzburg have developed a novel method for optical microscopy. Using biological motors and single quantum dots, they acquire ultra-high-resolution images.
The resolution of conventional optical microscopy is limited by the fundamental physical principle of diffraction to about one half of the wavelength of the light: If the distance between two objects is smaller than this so-called "diffraction limit", they can no longer be visually separated - their image appears "blurred ". To acquire optical images at the scale of few nanometers, this is clearly not sufficient.
