    "abstract": "Within a case study on the protein-protein interaction network (PIN) of\nDrosophila melanogaster we investigate the relation between the network\u0027s\nspectral properties and its structural features such as the prevalence of\nspecific subgraphs or duplicate nodes as a result of its evolutionary history.\nThe discrete part of the spectral density shows fingerprints of the PIN\u0027s\ntopological features including a preference for loop structures. Duplicate\nnodes are another prominent feature of PINs and we discuss their representation\nin the PIN\u0027s spectrum as well as their biological implications.",
