The invention provides methods for increasing resting metabolic rate, reducing waist circumference, and weight control by administering a composition comprising dietary fiber, phenylalanine, tyrosine, tea blend, caffeine, and Lycium plants or Lycium plant extract preparations to the subject. Electrodes are disposed near a semiconductor quantum dot coupled to a semiconductor optical cavity such that varying an applied bias at the electrodes alters an electric field at the quantum dot. First and second coupling portions are formed on the base frame and the mirror support frame to couple together. Upon receiving the wireless network information via its secondary communication interface, the first device may use it to acquire a communication service from the wireless network over a primary communication interface.
