Rev. Lett. 82, 867 (1999)]. Here we show that taking proper care of the effect of the time delay on the reactive process yields a different evolution equation and, therefore, an alternate equation for the front speed. We apply the new equation to the Neolithic transition. For this application the new equation yields speeds about 10% slower than the previous one" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "American Physical Society" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://link.aps.org/doi/10.1103/PhysRevE.80.057103" , "dc.relation.ispartof": "© Physical Review E, 2009, vol. 80, núm. 5, p. 057103" , "dc.relation.ispartofseries": "Articles publicats (D-F)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Equacions de reacció-difusió" , "dc.subject": "Reaction-diffusion equations" , "dc.subject": "Neolític -- Models matemàtics" , "dc.subject": "Neolithic period -- Mathematical models" , "dc.title": "Time-delayed reaction-diffusion fronts" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.embargo.terms": "Cap" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.doi": "http://dx.doi.org/10.1103/PhysRevE.80.057103" , "dc.identifier.idgrec": "011811" }
