(Top) Example of a SF network with the fixed absorbing node xa marked by black circle. (Bottom) FPT densities on SF network G(N; m; m0) N = 100, m = 1, m0 = 6 for different starting points x0 and a fixed absorbing node xa such that: ∣x0 − xa∣ = 1 (black), ∣x0 − xa∣ = 2 (blue), ∣x0 − xa∣ = 3 (red) (FPT densities with ∣x0 − xa∣ > 3 are shown in grey). The travel time distribution is \( {\tilde{\psi}}_{x{x}^{\prime }}(s)=1/{\left({s}^a{\tau}^a+1\right)}^2 \); a = 1, τ = 1, except in a fixed trap node at which α = 0.5
