Radius of gyration as a function of the distance from the wall, 𝑧[𝜎], for 𝑁_𝑝=10: (a) parallel component 𝑅_‖[𝜎] and (b) perpendicular component 𝑅_⟂[𝜎] for (■) 𝜀^𝑝_𝑏=𝜀^𝑝_𝑤=0, (●) 𝜀^𝑝_𝑏=𝜀^𝑝_𝑤=𝜀, and (▼) 𝜀^𝑝_𝑏=𝜀^𝑝_𝑤=2𝜀. Error bars indicate one-half of the standard deviation and are shown only for 𝜀^𝑝_𝑏=𝜀^𝑝_𝑤=𝜀.
