What is the interpretation of negative nonlinear Duffing stiffness (-x^3) in limit-cycle models of biologic rhythmic actions?

In modeling biologic rhythmic actions as limit-cycles, it has been reported that a negative Duffing term (i.e. -x^3) represents decreasing of variability near reversal points (or softening...
