In this paper, we propose an averaging method for expert segmentation proposals of microbial organisms, resulting in a smooth, naturally looking segmentation ground truth. The approach exploits a geometrical property of the majority of the organisms - star-shapedness - and is based on contour averaging in polar space. [...]

The combinatorial growth of the Hilbert space makes the many-electron problem one of thegrand challenges of theoretical physics. Progress relies on the development of non-perturbativemethods, based on either wavefunctions or self energies. [...]

This is the first time in the 51-year history of the IFF Spring School that the subject has been a “Technology”. Can there be two weeks of intensive lectures by top scientists on a mere technology? The decision just a few years ago, to designate $\textbf{Quantum Technology}$ as a coherent societal endeavour, was taken after much deliberation within a large circle of working scientists [...]

Topology and entanglement are key concepts in many-body physics. Understanding the as-sociated emergent phenomena beyond toy models – in the world of real strongly-correlatedmaterials – requires the mastery of a wealth of different methods. [...]

This paper addresses the issue of social inequality by comparing German household data (gross income, Food‐Energy‐(Watervirtual)‐Nexus expenditures) from2008 and 2013. The distribution of gross income and of the FE(Wvirtual)‐Nexus related consumption expenditures based on this income is analysed using a three stepapproach: First, the real distribution is determined, secondly, the dispersion (based on Rawls’ philosophical concept) is analysed, and finally, the normativedistribution according to the Atkinson index is calculated to reveal a view on social inequality.

On February 27 and 28, 2020 computational scientists will present their exciting research results at the 10$^{th}$ NIC symposium in Jülich. About 20 years after the first NIC symposium on December 5 and 6, 2001, this series of biannual meetings has established a valued tradition, highlighting a diverse range of some of the best, modern, computational science at the von Neumann Institute for Computing (NIC) [...]
