Only three biological pathways are known to produce oxygen: photosynthesis, chlorate respiration and the detoxification of reactive oxygen species. Here we present evidence for a fourth pathway, possibly of considerable geochemical and evolutionary importance. The pathway was discovered after metagenomic sequencing of an enrichment culture that couples(More)
— In this paper the feed-forward control structure is introduced for a manipulator joint driven by a set of symmetrical antagonistic muscles. The setup allows the specification of the desired joint angle, as well as the single muscle forces and produces the pressure signal for the muscles' supplying valves based upon the manipulator kinematic and the(More)
An important aim of the current research effort in artificial intelligence and robotics is to achieve cooperative agent behavior for teams of robots in real-world scenarios. Especially in the RoboCup scenario , but also in other projects like Nexus, agents have to cooperate efficiently to reach certain goals. In the RoboCup project, cooperative team-play(More)
BACKGROUND Microbial denitrification is not considered important in human-associated microbial communities. Accordingly, metabolic investigations of the microbial biofilm communities of human dental plaque have focused on aerobic respiration and acid fermentation of carbohydrates, even though it is known that the oral habitat is constantly exposed to(More)
BACKGROUND Bacillus subtilis 3610 displays multicellular traits as it forms structurally complex biofilms and swarms on solid surfaces. In addition, B. subtilis encodes and expresses nitric oxide synthase (NOS), an enzyme that is known to enable NO-mediated intercellular signalling in multicellular eukaryotes. In this study, we tested the hypothesis that(More)
