基金Improved family statistics were obtained for the Viviane model by P.M.C.de Oliveira,D.Stauffer,S.Wichmann,S.Moss de Oliveira,submitted,e-print 0709.0868 on arXiv.org,and for the Tuncay model by C.Tuncay,submitted to Int.J.Mod.Phys.C 19 in press(2008).Endangered languages were modelled by J.W.Minett,W.S.Y.Wang,Lingua,in press(2007).
