Effective viscosity of non-gravitactic Chlamydomonas Reinhardtii microswimmer suspensions
Matthias Mussler, Salima Rafai, Philippe Peyla +1
Active microswimmers are known to affect the macroscopic viscosity of suspensions in a more complex manner than passive particles. For puller-like microswimmers an increase in the…
Elastic models of the fast traps of carnivorous Dionaea and Aldrovanda
Marc Joyeux
The carnivorous aquatic Waterwheel Plant (Aldrovanda vesiculosa L.) and the closely related terrestrial Venus Flytrap (Dionaea muscipula SOL. EX J. ELLIS) both feature elaborate sn…
The remarkable discreteness of being
Bahram Houchmandzadeh
Life is a discrete, stochastic phenomena : for a biological organism, the time of the two most important events of its life (reproduction and death) is random and these events chan…
A model of H-NS mediated compaction of bacterial DNA
Marc Joyeux, Jocelyne Vreede
The Histone-like Nucleoid Structuring protein (H-NS) is a nucleoid-associated protein, which is involved in both gene regulation and DNA compaction. H-NS can bind to DNA in two dif…
Lift and down-gradient shear-induced diffusion in Red Blood Cell suspensions
Xavier Grandchamp, Gwennou Coupier, Aparna Srivastav +2
The distribution of Red Blood Cells in a confined channel flow is inhomogeneous and shows a marked depletion near the walls due to a competition between migration away from the wal…
