The mean value of first avalanche event strain. (A) $\mathrm{\Gamma }\left(\gamma \right)$ versus $\gamma$ for $N=\mathrm{10,000}$ in a 3D system. (A, Inset) Zooming in $\mathrm{\Gamma }\left(\gamma \right)$ vs. $\gamma$ curve for different thermal histories, the vertical line shows the mean value of first avalanche event strain $<{ϵ}_{\gamma }>{|}_{\gamma =0}$; from left to right is $T_{\text{ini}}=0.87,0.61,0.479$, respectively. (B) $<{ϵ}_{\gamma }>{|}_{\gamma =0}$ versus system size $N$ for different thermal histories in the 3D system. The dashed line is $N^{-0.66\pm 0.02}$ where the exponent is fitted to the data. (C) Evolution of $\theta$ with the strain window $\gamma$ for different thermal histories. The dashed line is the mean value of $\theta$ over the interval $\gamma \in \left[0.005,0.015\right]$. We define this value as the plateau value, from top to bottom, ${\theta }_{\text{Plateau}}=0.26\pm 0.01,0.21\pm 0.01,0.11\pm 0.01$ for $T_{\text{ini}}=0.87,0.61,0.479$, respectively. (D) Correlation between finite-size scaling exponents $\alpha$, $d_f/d$ and the exponent $\theta /\left(1+\theta \right){|}_{\text{Plateau}}$ in the 3D system.
