Twist dynamics of semiflexible polymer
A. C. Maggs
A number of strange results have been reported for the twist elasticity of a semiflexible filament, actin. In particular dynamic and static methods for determining the torsional tw…
Dispersion Relation of a Ferrofluid Layer of Any Thickness and Viscosity in a Normal Magnetic Field; Asymptotic Regimes
Berengere Abou, Gilles Neron de Surgy, Jose-Eduardo Wesfreid
We have calculated the general dispersion relationship for surface waves on a ferrofluid layer of any thickness and viscosity, under the influence of a uniform vertical magnetic fi…
On micro-bead mechanics with actin filaments
A. C. Maggs
Experiments have been performed using microscopic beads to probe the small scale mechanics of actin solutions. We show that that there are a number of regimes possible as a functio…
Two plateau moduli for actin gels
A. C. Maggs
Conflicting experimental results have been reported for the plateau modulus in actin solutions: Analogies are often made with the viscoelastic behaviour of flexible polymers making…
