Editing Small-world network (section)

==Examples of small-world networks==
Small-world properties are found in many real-world phenomena, including websites with navigation menus, food webs, electric power grids, metabolite processing networks, [[biological neural network|networks of brain neurons]], 
voter networks, telephone call graphs, and airport networks.<ref>{{cite journal | vauthors = Yang YC |date=1972 |title=Terminal Road Bridges for San Francisco International Airport Airport |journal= ACI Journal Proceedings|volume=69 |issue=10 |doi=10.14359/7189 }}</ref>  Cultural networks<ref>{{cite journal | vauthors = Senekal BA | title = 'n Kwantifisering van kleinwêreldsheid in Afrikaanse kultuurnetwerke in vergelyking met ander komplekse netwerke: natuurwetenskappe. | trans-title = A quantification of small worlds in African cultural networks compared to other complex networks: natural sciences. | language = af | publisher = Litnet Akademies | journal ='n Joernaal vir die Geesteswetenskappe, Natuurwetenskappe, Regte en Godsdienswetenskappe | date = December 2015 | volume = 12 | issue = 3 | pages = 665–88 | url = http://www.litnet.co.za/n-kwantifisering-van-kleinwereldsheid-in-afrikaanse-kultuurnetwerke-in-vergelyking-met-ander-komplekse-netwerke/ }}</ref> and word [[co-occurrence network]]s<ref>{{cite journal | vauthors = Senekal B, Kotzé E | title = Die statistiese eienskappe van geskrewe Afrikaans as'n komplekse netwerk. | trans-title = The statistical properties of written Afrikaans as a complex network | language = af | publisher = Litnet Akademies | journal = 'n Joernaal vir die Geesteswetenskappe, Natuurwetenskappe, Regte en Godsdienswetenskappe | date = 2017 | volume = 14 | issue = 1 | pages = 27–59 | url = http://www.litnet.co.za/die-statistiese-eienskappe-van-geskrewe-afrikaans-n-komplekse-netwerk/ }}</ref> have also been shown to be small-world networks.

Networks of [[protein–protein interaction|connected proteins]] have small world properties such as power-law obeying degree distributions.<ref>{{cite journal | vauthors = Bork P, Jensen LJ, von Mering C, Ramani AK, Lee I, Marcotte EM | title = Protein interaction networks from yeast to human | journal = Current Opinion in Structural Biology | volume = 14 | issue = 3 | pages = 292–9 | date = June 2004 | pmid = 15193308 | doi = 10.1016/j.sbi.2004.05.003 | url = http://marcottelab.org/paper-pdfs/cosb-review.pdf }}</ref> Similarly [[transcriptional regulation|transcriptional network]]s, in which the nodes are [[gene]]s, and they are linked if one gene has an up or down-regulatory genetic influence on the other, have small world network properties.<ref>{{cite journal | vauthors = van Noort V, Snel B, Huynen MA | title = The yeast coexpression network has a small-world, scale-free architecture and can be explained by a simple model | journal = EMBO Reports | volume = 5 | issue = 3 | pages = 280–4 | date = March 2004 | pmid = 14968131 | pmc = 1299002 | doi = 10.1038/sj.embor.7400090 }}</ref>
