Query: On the relationship between the plateau modulus and the threshold
  frequency in peptide gels   Relations between static and dynamic viscoelastic responses in gels can be
very elucidating and may provide useful tools to study the behavior of
bio-materials such as protein hydrogels. An important example comes from the
viscoelasticity of semisolid gel-like materials, which is characterized by two
regimes: a low-frequency regime where the storage modulus $G^{\prime}(\omega)$
displays a constant value $G_{\text{eq}}$, and a high-frequency power-law
stiffening regime, where $G^{\prime}(\omega) \sim \omega^{n}$. Recently, by
considering Monte Carlo simulations to study the formation of peptides
networks, we found an intriguing and somewhat related power-law relationship
between the plateau modulus and the threshold frequency, i.e. $G_{\text{eq}}
\sim ( \omega^{*} )^{\Delta}$ with $\Delta = 2/3$. Here we present a simple
theoretical approach to describe that relationship and test its validity by
using experimental data from a $\beta$-lactoglobulin gel. We show that our
approach can be used even in the coarsening regime where the fractal model
fails. Remarkably, the very same exponent $\Delta$ is found to describe the
experimental data.
