摘要
A common feature of 生物 網絡s is the geometrical property of self-similarity. Molecular regulatory 網絡s through to circulatory systems, nervous systems, 社會 systems and ecological 營養級 網絡s show self-similar connectivity at multiple scales. We analyse the relationship between topology and signalling in contrasting classes of such topologies. We find that 網絡s differ in their ability to contain or propagate signals between arbitrary nodes in a 網絡 depending on whether they possess branching or loop-like features. 網絡s also differ in how they respond to noise, such that one allows for greater integration at high noise, and this performance is reversed at low noise. Surprisingly, small-world topologies, with diameters logarithmic in system size, have slower dynamical time scales, and may be less integr
