We measure the network robustness (functioning) with four indicators. The node attack strategies and the network robustness indicators consider both the binary-topological and the weighted structure of the network. First, we find that the well-known node betweenness centrality attack, which has proven highly effective in dismantling most real-world networks\u2019 topological connectivity, is ineffective over the PSI network. Second, the degeneracy of the node properties caused by the PSI\u2019s higher network connectivity level induces a random-like node removal even when nodes are removed according to a specific node centrality measure. This phenomenon triggers a very low decrease of the PSI network functioning even when subjected to node attack. Such an outcome would indicate that the node attack strategies based on classic node properties, such as the degree or the betweenness centrality, may show low efficacy in dismantling real-world networks with very high connectivity levels.<\/jats:p>\n               <jats:p>Last, the PSI network can be built by tuning a cut-off distance (CD) that defines the viable energy transfers among nodes\/chromophores and progressively discards the lower energy transfer links among distant nodes\/chromophores. This represents a \u2018weight thresholding\u2019 procedure allowing us to investigate the efficacy of the node attack strategies when links of lower weight are progressively pruned from the PSI network. We find that the best node attack strategies change by decreasing the CD, showing that the weight thresholding procedure affects the network response to node removal. This last outcome outlines the importance of investigating the stability of the system response for real-world weighted complex networks subjected to the weight thresholding procedure.<\/jats:p>","DOI":"10.1093\/comnet\/cnab050","type":"journal-article","created":{"date-parts":[[2021,12,7]],"date-time":"2021-12-07T13:52:02Z","timestamp":1638885122000},"source":"Crossref","is-referenced-by-count":6,"title":["The robustness of the photosynthetic system I energy transfer complex network to targeted node attack and random node failure"],"prefix":"10.1093","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5729-1123","authenticated-orcid":false,"given":"M","family":"Bellingeri","sequence":"first","affiliation":[{"name":"Dipartimento di Scienze Matematiche, Fisiche e Informatiche, Universit\u00e0 di Parma, via G.P.
