a Average strength s(k) as a function of degree k in logarithmic coordinates. The data points are fitted to a straight line, showing the relation s(k) ∼ kβ.b Node strengths of the PPI network sorted in descending order. c Disparity Y(k) in the edge weight decays as a function of k. The data points are well approximated by the curve Y(k) = 1/k
