Entrainment ranges as a function of the forcing position for varying intersegmental connections. Uniform coupling asymmetry is illustrated in A with \(A_{a}=0.0004\), \(A_{d}=0.0002\), and \(\lambda_{a}=\lambda_{d}=4\). All of the ascending coupling strengths are stronger than descending for all connection lengths. This coupling scheme is used to produce monotonic entrainment ranges as a function of the forcing position, seen in C. Nonuniform coupling asymmetry is depicted in B with \(A_{a}=0.006\), \(A_{d}=0.0004\), \(\lambda_{a}=0.75\), and \(\lambda_{d}=4\). For our choice of parameters, ascending connections become stronger at connections of length 3. Nonuniform coupling is used to compute the entrainment range in D, where see non-monotonic entrainment ranges
