A method and apparatus for indexing and locating key frames in streaming frame data and variable-frame-length data is described. The polymer scaffold embodies macropores having a diameter in a range of 0. Then, the medicine can be capped off with a stopper and the nipple attached to a standard baby bottle with milk or formula mixture within it. The memory is accessed with the plurality of threads to concurrently process a plurality of the messages. Circuit macros placed within the voltage island are modeled as current sources. A method for operating a current source arrangement is also specified.
