A method and apparatus are provided for transmitting a sounding reference signal in a communication system. A system compensates for respiratory motion induced tissue displacement in cardiac wall motion determination. The nitrogen is subsequently thermally annealed within the layer to bond at least some of the nitrogen to silicon within the layer. Also disclosed are photoresists formulations containing the functionalized polycarbosilanes that are suitable for use in lithography, e. Methane and carbon dioxide are passed through a carbon-containing granular material and reacted in a high-temperature zone. In this way, throughput degradation of the NoC system can be prevented.
