    "abstract": "It was first suggested by Englander et al to model the nonlinear dynamics of\nDNA relevant to the transcription process in terms of a chain of coupled\npendulums. In a related paper [q-bio.BM/0604014] we argued for the advantages\nof an extension of this approach based on considering a chain of double\npendulums with certain characteristics. Here we study a simplified model of\nthis kind, focusing on its general features and nonlinear travelling wave\nexcitations; in particular, we show that some of the degrees of freedom are\nactually slaved to others, allowing for an effective reduction of the relevant\nequations.",
