A method, simulation, and apparatus are provided that are highly suitable for treatment of benign prostatic hyperplasia. The method of nano-patterning block copolymers includes coating block copolymers on a lower substrate to a predetermined thickness, forming a thickness gradient by patterning the block copolymers to have a predetermined aspect ratio, and aligning self-assembled block copolymers in a direction of the thickness gradient by heat-treating the block copolymers having the thickness gradient. In one embodiment, the tube surface is bare. When the user turns on the antenna function of the laptop to receive RF signals, the antenna unit and the light-emitting unit can respectively receive RF signals and DC. In the second position, the portion of the second section is exposed to the players, and influences the outcome of at least a portion of the game.
