Leloup and Goldbeter, 1998 This model was created after the article by Leloup and Goldbeter, J Biol Rhythms 1998, Vol:13(1),pp70-87, pubmedID: 9486845 A Model for Circadian Rhythms in Drosophila Incorporating the Formation of a Complex between the PER and TIM Proteins The parameters and initial concentrations are taken to reproduce figs. 4 D,E,F in the publication. For a simulation without light dependent degradation of TIM_pp, change the the parameter v_dT_fac to 1. The light/dark phases length can be set using the parameter l_d .
