Hartwig Anzt, UT/KITFaster algorithms through multiprecision format

Multiprecision algorithms mix different precision formats to get faster computation run-time – currently saving up to 20%. While preserving double-precision quality in the output, intermediate calculations can run on a lower precision format. In memory bound algorithms, where the data transfer volume slows down the computation, more-compact precision formats can reduce the pressure on the memory bandwidth. Hence, decoupling of the arithmetic from the memory format is essential, says Hartwig Anzt in a Let’s Talk Exascale podcast. As multiprecision algorithms are not limited to special-function units, a strong focus lies on interoperability.

KATRIN SpectrometerPhys.Rev.Lett. cover: new limit for neutrino mass

The international Karlsruhe Tritium Neutrino Experiment (KATRIN) has improved the upper limit of the neutrino mass almost by the factor of 2 and made it on the cover of the Physical Review Letters. Based on a purely kinematic method, KATRIN has narrowed down the absolute mass of neutrinos to less than 1.1 electron-volt (eV) at 90% confidence within only four weeks. After 1000 days of data taking, an even higher sensitivity of 0.2 eV will be reached. YIN speaker Kathrin Valerius coordinates the analysis activities at KIT. Overall 20 institutions from 7 countries are part of the KATRIN collaboration.

Geometry-optimized DFT model of the ground-state of CB8⊃MPCP featuring an ideal packing coefficient (PC) of 57%.Smart sensors for personalized medication

Swiftly measuring and adapting the concentration of active medical substances within the body – Frank Biedermann and his team present a simple, inexpensive method for the Alzheimer medication Memantin in the journal Chemical Science. There, a molecule serves as synthetic receptor dye and “hides” in a second, barrel-shaped molecule. When the active agent displaces the dye, the latter can be determined in medically relevant concentrations in the blood serum outside the barrel molecule. The scientists also issued a guideline on how to transfer the method to other medications and dyes.

Blog_GinkgoWorkingTeamsoftware contributions counting towards h-index

Offering full reproducibility and open source code, software contributions can be more beneficial to the scientific community than classical publications. However, they do not count towards impact metrics like the H-index. To instigate a change, software contributions could become acceptable as a full-value conference submission to be included in the proceedings after an additional independent review. In the blog Better Scientific Software, Hartwig Anzt argues that a community-based assessment would reduce the workload of the independent reviewer and ensure a very high quality.

Photoelektronenspektroskopiencomms: Charakterisierung von Elektrolytlösungen

Reaktionen an den Grenzflächen zwischen Elektrolytflüssigkeit und Elektroden entscheiden mit über Kapazität und Lebensdauer von Lithium-Ionen-Batterien. Hier bildet sich eine Schicht, die als Elektrodenschutz wirken kann, aber auch Ladung verbraucht und zu Kapazitätsverlusten führt. "Mit schwedischen Kollegen haben wir erstmals Lösemittel und Elektrolytlösung mittels Photoelektronen-Spektroskopie untersucht und dabei die flüssige Phase über längere Zeit aufrechterhalten", so Julia Maibach. Maßgebend war der stabilisierende Umgebungsdruck des Lösemittels in Gasform.

doi: 10.1029/2018MS001592Wolken beeinflussen Jet-Streams im Klimawandel

Jet-Streams geben die Zugbahnen außertropischer Stürme vor und bestimmen damit das regionale Klima und Wettergeschehen maßgeblich. Der Klimawandel wird die Position und Intensität der Jet-Streams verändern und so auch die Häufigkeit starker Stürme außertropischen Ursprungs. Wie die BMBF-Nachwuchsgruppe „Wolken und Sturmzugbahnen“ um Aiko Voigt nun herausfand, hängt die Reaktion der Jet-Streams auf den Klimawandel zu einem Großteil von Wolken ab: Ein bis zwei Drittel der polwärtigen Verschiebung sowie die Verstärkung im Nordatlantik und im südlichen Ozean gehen auf Wolken zurück.

Weltweit fallen die Grundwasserpegel und die Qualität verschlechtert sich. Um Grundwasserressourcen kostengünstig und flächen- deckend zu untersuchen, hat Gabriel Rau gemeinsam mit australischen Kollegen eine neue Methode entwickelt: Ein Drucksensor erfasst gezeiten- abhängigen Schwankungen des Grundwasserpegels, denn die sich ändernde Gravitation wirkt auch im Boden. Anhand der Messungen berechnen die Forscher etwa Porösität, hydraulische Leitfähigkeit und Kompressibilität des Untergrunds. Auf klassische Pumpversuche und angelegte Brunnen können sie verzichten.
