Onion structure and network robustness
In a recent work [Proc. Natl. Acad. Sci. USA 108, 3838 (2011)], Schneider et al. proposed a new measure for network robustness and investigated optimal networks with respect to this quantity. For networks with a power-law degree distribution, the optimized networks have an onion structure-high-degree vertices forming a core with radially decreasing degrees and an over-representation of edges wi...
متن کاملOnion-like network topology enhances robustness against malicious attacks
We develop a method to generate robust networks against malicious attacks, as well as to substantially improve the robustness of a given network by swapping edges and keeping the degree distribution fixed. The method, based on persistence of the size of the largest cluster during attacks, was applied to several types of networks with broad degree distributions, including a real network—the Inte...
متن کاملNetwork Structure and Robustness of Intracellular Oscillators
Sustained oscillations play a key role in many intracellular functions, such as circadian time keeping, cell cycle control and calcium signalling. The oscillations are in all cases driven by feedback interactions taking place in biochemical reaction networks. While a single feedback loop in principle is sufficient to generate such oscillations, experimental evidence reveal that more complex net...

متن کاملRobustness of onion-like correlated networks against targeted attacks
Recently, it was found by Schneider et al. [Proc. Natl. Acad. Sci. USA 108, 3838 (2011)], using simulations, that scale-free networks with "onion structure" are very robust against targeted high degree attacks. The onion structure is a network where nodes with almost the same degree are connected. Motivated by this work, we propose and analyze, based on analytical considerations, an onionlike c...
