abstract = {The dynamical behavior of vesicles is investigated in
simple shear flow. A simulation technique is presented that
combines a three-dimensional particle-based mesoscopic model
(multiparticle collision dynamics) for the solvent with a
dynamically triangulated surface model for the membrane. In
this model, thermal fluctuations of the solvent and of the
membrane are consistently taken into account. The membrane
viscosity can be varied by changing the bond-flip rate of
the dynamically triangulated surface. Vesicles are found to
transit from steady tank-treading to unsteady tumbling
motion with increasing membrane viscosity. At small reduced
volumes, the shear induces a transformation from a discocyte
to a prolate shape at low membrane viscosity. On the other
hand, at high membrane viscosity, the shear induces a
transformation from prolate to discocyte, or tumbling motion
accompanied by shape oscillations between these two states.
Thermal fluctuations induce intermittent tumbling and smooth
out the transitions. This effect can be understood from a
simplified stochastic model.},
