A 5D Horndeski braneworld produces Friedmann equations with Cardassian rho^(+/-1/2) terms (strong L5 coupling) and rho^3 plus dark-radiation-matter terms (weak coupling), with a cosmological constant from the bulk scalar and no brane tension.

Nonlinear matter terms in general scalar-tensor braneworld cosmology
A 5D Horndeski braneworld produces Friedmann equations with Cardassian rho^(+/-1/2) terms (strong L5 coupling) and rho^3 plus dark-radiation-matter terms (weak coupling), with a cosmological constant from the bulk scalar and no brane tension.
