In this year’s competition of the international scientific association, EUNITE, three teams have succeeded in predicting the temporal development of the five response signals in the process control of a glass melting tank (with 29 input parameters) over a period of two weeks. The – weighted – deviation of the modelled values from the real values was 0.3 per cent. The winners will present their results at the EUNITE Conference from 10th to 12th July in Oulu, Finland. As an expression of its gratitude, Schott Glas will award prizes in the amounts of 5000 € (1st place), 3000 € (2nd place), and 1000 € (3rd place). “We could not actually apply the concrete values from the prediction for plant control, perhaps because some decisive parameters had not yet been recorded, but the proposed model approaches are of great value to us”, said Dr. Katharina Lankers, who had arranged the competition on behalf of Schott Glas.
EUNITE is a European association of scientists at universities and in industry; it is supported by the European Union with the objective of forming a network for excellence. EUNITE is dedicated to improvements in so-called intelligent, adaptable systems. The modelling abilities of the scientists are tested in an annual competition. The competition is coordinated by Lecturer Dr. Jens Strackeljan at the Institute of Technical Mechanics at the Technical University of Clausthal.
The winners are Marcin Wojnarski at the University of Warsaw, Poland, first place; Dr. Bernhard Pfahringer at Waikato University in New Zeeland, second place; Dr. Dumitru-Iulian Nastac and Adrain Costea at the Computer Science Centre in Turku, Finland, third place. A total of twenty proposed solutions were received, some of them from the United States and Brazil, among other countries.

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
