abstract = {Shear-induced flow instabilities is the instability of the
shear-gradient concentration coupling (SCC)-instability due
to coupling of shear-gradient induced mass transport and
concentration [1, 2]. This leads to a self-amplifying
increase of spatial gradients of the shear rate, provided
that the viscosity is sufficiently strong depending on the
concentration. The origin of the shear-gradient induced mass
flux will be discussed, as well as the stationary flow- and
concentration-profiles for the systems of yield stress
(glassy) hard-spheres [3].[1] J.K.G. Dhont, K. Kang, M.P.
