The present invention provides systems and methods for extending media retention. The gate electrode extends from within the second opening to above the first compound semiconductor layer. Micro-reflectors 19 in each of areas ARA to ARC are orientated as to be directed to each of LEDs 14A to 14C correspondingly, effecting an effective direction conversion. The high-level object-oriented specification language supports class definitions that model hardware and virtual resources as well as software roles and service roles served by software applications and services in a cloud-based deployment.
