Systems and methods for improving the heart rate coherence andor heart rate variability of a subject use a respiratory therapy device to provide breathing cues that prompt a subject to breathe such that various respiratory and coronary parameters are aligned, for example in phase. The plurality of transport media define at least two groups of transport media, where each group of transport media has substantially identical transverse dimensions with respect to one another within one group of transport media, while having substantially different transverse dimensions with respect to another group of transport media. A migration manager can migrate the service between servers in the migratable target, and can activate an instance of the service on the selected host server. The CRC logic calculates possible CRC values for the packet using combinations of the selected symbols.

The method further comprises converting the second markup representation of the external document into a first markup representation of the external document, and incorporating the first markup representation of the external document into the first document.
