Human CRB genes are identified as modulators of branching morphogenesis, and thus are therapeutic targets for disorders associated with defective branching morphogenesis function. This invention, consists of recording thin film of ternary elements, for example, containing Ge, Te, Sbor Bi or quaternary elements containing the fourth element of Se with which a part of Te is replaced, which is established on such surface\u2014flat substrates as glass or plastics. A write signal generation circuit generates a first write signal, which is written to the CD, from the first modulated data, and a second write signal, which is written to the DVD, from the second modulated data. A high frequency ballast is integral to the outer glass tube and configured to provide a high frequency AC waveform for driving electrodes configured for energizing the plasma-forming gas within the inner glass tube to form plasma paths therein. The controller elements may be thumb-sticks.
