The combination of spectroscopic and diffraction methods to study chemical transformations is fundamental for the understanding of reaction mechanisms. The identification of short-lived species, likely active species, is often hindered by the contribution of spectator s...

a b s t r a c t Several multi-year biodiversity experiments have shown positive species richness-productivity rela- tionships which strengthen over time, but the mechanisms which control productivity are not well understood. We used experimental grasslands (Jena Experim...

This working papers provides a collection of the questionnaires as well as other forms used for the conduct of the Mobidrive travel survey. The documents are given in their original version complemented by a brief English translation.

This paper discusses a computational method for optimally allocating dimensional tolerances for an automotive pneumatic control valve. Due to the large production volume, costly tight tolerances should be allocated only to the dimensions that have high influence to the ...

HD 219134 is a K-dwarf star at a distance of 6.5 parsecs around which several low-mass planets were recently discovered. The Spitzer space telescope detected a transit of the innermost of these planets, HD 219134 b, whose mass and radius (4.5 MEarth and 1.6 REarth respe...

SummaryChemokines orchestrate immune cell trafficking by eliciting either directed or random migration and by activating integrins in order to induce cell adhesion. Analyzing dendritic cell (DC) migration, we showed that these distinct cellular responses depended on the...

Human voices are individual and humans have elaborate skills in recognizing speakers by their voice, phenomena that are deeply rooted in the evolution of human behavior. To date, the mechanisms of speaker recognition are not well understood because of the high variabili...
