Volcanological studies of Neogene flood basalt groups in eastern Iceland
Flood basalt groups in the Neogene lava piles of eastern Iceland are subject to investigation. The groups form the stratigraphic section above the Reyðarfjörður central volcano up to the Thingmuli central volcano, mapped by the British geologist G. P. L. Walker and his students in the 1950s and …

Constraint-based modeling of host-microbe and microbe-microbe metabolic interactions in the human gut
Humans harbor a complex microbial ecosystem in their intestines. This human gut microbiota performs essential functions for host health and wellbeing. Disruption, or dysbiosis, in gut microbiota composition has been directly linked to the pathogenesis of complex diseases. Understanding the …

Implementation and reassessment of the Perdew-Zunger self-interaction correction
Density functional theory (DFT) using semi-local functional approximations can describe many chemical properties to high accuracy, but in some cases large and even qualitative errors emerge. Some of these errors are ascribed to an unphysical interaction of each electron with itself, which is …

Simulation-Based General Game Playing
The aim of General Game Playing (GGP) is to create intelligent agents that automatically learn how to play many different games at an expert level without any human intervention. One of the main challenges such agents face is to automatically learn knowledge-based heuristics in real-time, whether …
