We present HeAT, a scientific big data librarysupporting transparent computation on HPC systems. HeATbuilds on top of PyTorch, which already provides many requiredfeatures like automatic differentiation, CPU and GPU support,linear algebra operations and basic MPI functionality as well asan imperative programming paradigm allowing fast prototypingessential in scientific research.

This manuscript to the proceedings of the ExtremeData – Demands, Technologies, and Services – Workshop1,gives an overview on the characteristics, components, steps andmethods of a complex data flow path around a fully coupledregional Earth system model and highlights the challenges weface working with very large data, as well as the concepts andstrategies towards a big data-enabled modeling chain..

The atmospheric oxidation of aromatic compounds leads to highly oxidized intermediates with oxygenation ratios O:C nearing or exceeding unity, and contributes efficiently to the formation of secondary organic aerosols and ozone. The intermediates in the mechanism differ strongly from those in aliphatic or unsaturated compounds oxidation, with multifunctionalization showing cyclic peroxides, epoxides, hydroperoxides, resonance-stabilized alkyl radicals, peroxy- and alkoxy radicals, and other functionalities.

Emergency exits as bottlenecks in escape routes are important for designing traffic facilities. Especially the fundamental diagram is a crucial performance criterion for assessment of pedestrians' safety in facilities and an important basis for calculation methods. [...]

For a proper understanding and modeling of pedestrian dynamics reliable empirical data are needed. Often the level of heterogeneity of pedestrians in laboratory experiments does not correspond with the level in the field. [...]

Über die Medien veröffentlichte Bilder von Unfällen mit zahlreichen Toten und Verletzten im Rahmen von Großveranstaltungen haben sich – spätestens seit den Ereignissen bei der Loveparade 2010 in Duisburg – in unser kollektives Gedächtnis eingeprägt. Welche Mängel oder Fehlentscheidungen sind aber ursächlich für diese Unfälle? Bei einer genaueren Analyse zeigt sich oft wie schwierig es ist zu ermitteln, welche Ursachen zu welchen Wirkungen und letztlich zum Schaden geführt haben. [...]
