Small-scale dynamo with finite correlation times

Fluctuation dynamos occur in most turbulent plasmas in astrophysics and are the prime candidates for amplifying and maintaining cosmic magnetic fields. A few analytical models exist to describe their behavior, but they are based on simplifying assumptions. ...

The accreted nuclear clusters of the Milky Way

Carmela Lardo

A number of the massive clusters in the halo, bulge, and disc of the Galaxy are not genuine globular clusters (GCs) but instead are different beasts altogether. They are the remnant nuclear star clusters (NSCs) of ancient galaxies since accreted by the Mil ...

Chromate tolerance and removal of bacterial strains isolated from uncontaminated and chromium-polluted environments

Rizlan Bernier-Latmani, Imrich Barak, Zuzana Chromiková

Investigation of bacterial chromate tolerance has mostly focused on strains originating from polluted sites. In the present study, we isolated 33 chromate tolerant strains from diverse environments harbouring varying concentrations of chromium (Cr). All of ...

High-temperature copolyamides obtained by the efficient transamidation of crystalline-crystalline polyamide blends

Véronique Michaud, John Christopher Plummer, Holger Frauenrath, Sylvain Cyril Claude Galland

High-performance thermoplastic composites based on semiaromatic polyamides are prime candidates for metal replacement in lightweight structural applications. However, the low ductility and toughness of semiaromatic polyamides remain major obstacles to thei ...

Metal-organic coordination interactions in Fe-Terephthalic acid networks on Cu(100)

Klaus Kern, Giovanni Costantini

Metal-organic coordination interactions are prime candidates for the formation of self-assembled, nanometer-scale periodic networks with room-temperature structural stability. We present X-ray photoelectron spectroscopy measurements of such networks at the ...

Delta-like 4 is the essential, nonredundant ligand for Notch1 during thymic T cell lineage commitment

Freddy Radtke, Ute Koch, Alexandre José Pessanha De Oliveira Caimoto Duarte

Thymic T cell lineage commitment is dependent on Notch1 (N1) receptor-mediated signaling. Although the physiological ligands that interact with N1 expressed on thymic precursors are currently unknown, in vitro culture systems point to Delta-like 1 (DL1) an ...
