    Descriptive info: › Research.. What have the neurons in our brain in common with roads, internet servers and airline flights? They form complex networks.. Networks are everywhere.. In particular in biology networks appear on many different scales and in many different contexts, ranging from the pattern of interaction between genes to networks of social contacts that form the backbone of our society; and even further to ecological interactions between species.. The structure and dynamics of complex networks is linked to many central questions of theoretical biology such as the stability of ecosystems, the spreading of diseases and the functioning of our bodies.. Insights in the dynamics of biological networks can help us to combat diseases and protect the environment.. Moreover, they can reveal important design patterns that lend natural systems their ability to self-organize robustly.. Once such patterns have been discovered  ...   on the developement and application of new powerful theoretical tools for the study of complex biological networks.. We collaborate closely with experts from various fields to apply our methods to a wide range of applications.. While our approaches are based on fundamental insights in theoretical physics and mathematics, our work is driven by important actual questions from the applied research.. Research Topics.. Opinion Formation.. 7 publications.. (more).. Adaptive Networks.. 16 publications.. Evolution and failure of cooperation.. 8 publications..

That keeping the people informed of a complex world empowers each individual, and helps people make the best choices for the whole of society.. According to a new study published in the journal Science, however, we've got it all backwards.. The conclusion of the study is that the health of a democracy is dependent on keeping people UN-informed.. Or some of them, anyway.. Ignorance can promote democracy: study.. PTI,.. Firstpost..

  • Title: Amplitude death in networks of delay-coupled delay oscillators | Biond Group Homepage
    Descriptive info: ›.. › Amplitude death in networks of delay-coupled delay oscillators.. Johannes Höfener, Gautam Sethia, and Thilo Gross.. Philosophical Transactions of the Royal Society A.. 371, 20120462, 2013.. arXiv:1210.. 2002.. Abstract.. Amplitude death is a dynamical phenomenon in which a network of oscillators settles to a stable state as a result of coupling.. Here, we study amplitude death in a generalized model of delay-coupled delay oscillators.. We derive analytical results for degree homogeneous networks that show that amplitude death is governed by certain eigenvalues of the network's adjacency matrix.. In particular these results demonstrate that in delay-coupled delay oscillators amplitude death can occur for arbitrarily large coupling strength k.. In this limit we find a region of amplitude death, which occurs already at small coupling delays that scale with 1/k.. We show numerically that these results remain valid in random networks with heterogeneous degree distribution.. Links.. This paper in Philosophical Transactions of the Royal Society A..
