Figure 3: Characterization of the pair class.
From: Structure–dynamics relationship in coherent transport through disordered systems
(a) The most efficient structure: pair and backbone sites are shown in dark and light grey, respectively. (b) Efficiency loss upon pair removal as a function of the original efficiency ε. Error bars are calculated according to the standard deviation. (c,d) Comparison of the typical dynamics with and without the pairs. The coherent signal does not focus in the output site in the absence of the pair sites, resulting in an efficiency loss 
of up to 0.32 (in the plot the dynamics of the most efficient structure is shown, where 
).
