Table 1.

Default nondimensional parameter values used in simulations of the full model. These values produce a reflecting pulse. Bracketed values produce a wave train. The abbreviation NPF represents the regulatory protein. Values for most dimension-carrying NPF parameters are based on small GTPases in [32], and lead approximately to the above dimensionless values based on scaling discussed in Appendix B.
