A Possible Origin of the Mass-Metallicity Relation of Galaxies

J. Koeppen, C. Weidner, P. Kroupa

Observations show that galaxies follow a mass-metallicity relation over a wide range of masses. One currently favoured explanation is that less massive galaxies are less able to re…

Intra-cellular transport by single-headed kinesin KIF1A: effects of single-motor mechano-chemistry and steric interactions

Philip Greulich, Ashok Garai, Katsuhiro Nishinari +2

In eukaryotic cells, many motor proteins can move simultaneously on a single microtubule track. This leads to interesting collective phenomena like jamming. Recently we reported ({…
