32. ⊥ denote the polarizabilty along directions parallel (∥) and perpendicular (⊥) to the tube backbone.
33. The cartoon depicted in Fig. 1 suggests how the semiflexible nature of the tube shape might translate into an effectively larger tube width, or radius of gyration, which for the sake of simplicity we have crudely described here with a 2D model of high-aspect-ratio rectangles in the x-z plane.
