9. As discussed in the following sections, the polymer chains undergo a conformational transition, from a "confined" state to an "escaped" state, under compression. Although this transition is referred to as a "phase" transition in earlier papers, we shall use the term "conformational" transition to avoid confusion.

19. This comment also applies to lattice-based computer simulations. That is, even though we observe a transition region between the two states, the details of how the force changes within the transition region as a function of H are difficult to determine with lattice-based models. Off-lattice simulations, which permit finer intervals in H, are required for this particular task.
