A service is configured on a network device. The detector detects an illuminance of ambient light received by the photoreceptor unit, on the basis of the electric signal. The projection extends between the end portions of the connection portions located at the opposite ends of the wave crest portion and the wave trough portion. The invention also provides pharmaceutically acceptable compositions comprising said compounds and methods of using the compositions in the treatment of various disease, conditions, or disorders.
