$\sigma_{F, xy}=\gamma_2 \sigma_{F, xx}/\gamma_1$ are obtained as the low $T$ limit of the renormalized Aslamasov-Larkin (AL) fluctuation conductivities \[38\], where $R_q$ is the resistance quantum $\pi \hbar/2 e^2$. According to eq.(4.1) of ref.6, the corresponding diagonal AL conductivity parallel to ${\bf B}$ has the following low $T$ form obeying the LLL scaling $$\sigma_{F, zz} \simeq \sigma_{F, xx} \biggl(-{{2 \pi \xi_0^2 \, r_B \,
\mu_0}
\over {b k_{\rm B} T \Gamma}} \biggr)^2 \propto {{(T_c(B) - T)^3} \over
{(B
k_{\rm B} T \Gamma)^2}}. \eqno(2.20)$$ The same relation was derived later in ref.39 in terms of the phase-only model. It suggests that the behavior (2.20) of $\rho_{zz}$ is also valid in the liquid regime in lower fields.

Below, we focus on the glass fluctuation term $\sigma_{G, xx}$. The Feynman diagrams expressing $\sigma_{G, xx}$ are illustrated in Fig.2. In weak enough pinning case, the resistive vanishing can be described just by Fig.2 (a), while Fig.2 (b) becomes necessary in order to derive the universal VG scaling.

Actually, assuming the glass transition to be continuous, Fig.2 (a) gives \[17\] $$\sigma_{G, xx}^{(a)} \sim (T-T_{\rm VG})^{(3-z)\nu}, \eqno(2.21)$$ while the diagrams such as Fig.2 (b) result in the scaling behavior \[20\]
