Entropy is an important but largely misunderstood quantity. A lot of this confusion arise from its original formulation within the framework of Thermodynamics. Looking at it from a microscopic point of view (i.e. approaching it as a Statistical Mechanics problem) makes it a lot more digestible, but its ties to Thermodynamics still creates a lot of unnecessary complications.
In this paper the authors suggest that by removing the forced connection between entropy and the Kelvin temperature scale, one can rethink entropy purely in terms of information capacity of a Physical system, which takes away a lot of the difficulties usually plaguing the understanding of what entropy is actually about.
I don't think the SI will ever consider their suggestion to remove Kelvins as a fundamental unit and include bits, but this paper will be a great boon to any student banging their head against the idea of entropy for the first (or second, or third) time.

Our article on the #mechanics of "active" entropic biopolymer networks [possibly including #actomyosin, this is debated experimentally] is now published in J Elas.

Compared to enthalpic models, we're able to go right from the #thermodynamics of an unbiased #molecularMotor activity (in the spirit of the model by #JacquesProst for #myosin) at the molecular scale to a network-scale model in a closed form.

And we derive a method for solving quite easily the (usually tough) #viscoelastic #liquid model that we obtain, using #deformationGradientDecomposition.
