“…Yochelis et al [ 151 ] showed that the minimal IAW model in one space dimension, in the setting of Equations (5), may indeed support rich and robust spatiotemporal dynamics following pulse collisions, in contrast to IAW models which do not contain explicit mass conservation [ 28 , 55 , 81 , 163 , 164 ]: Annihilation, reflection, and “birth” of new pulses after reflection, as shown in Figure 3 . In a broader RD context, where similar aspects have been also observed, these dynamics do not require special properties, such as non-locality [ 165 , 166 , 167 , 168 ], cross-diffusion [ 169 ], and heterogeneity [ 170 , 171 , 172 ].…”
