(A) Approximation of the repulsive part of the first peak of $g\left(r\right)$ using two different values for the steepness λ. An increase in λ is linked to a steeper slope of $g\left(r\right)$. (B) In the high-frequency regime the affine shear modulus represents a good approximation to the actual behavior of the shear modulus $G=G_{\text{A}}-G_{\text{NA}}$.
