The invention relates to phosphites comprising substituted or unsubstituted tricyclodecylmethyl groups. The method also includes using a parallel imaging technique to acquire gated MR data from the localized slice and reconstructing a prescribed fixed number of gated MR images of the localized slice. The Mobile Node first attempts to register with its primary Home Agent. Each of the virtual ROM modules is assigned a generated unique identifier, and a \u201cmessage digest\u201d is constructed for each module using an algorithm such as MD5 or SHA-1. The optimal ranking algorithm is defined by a plurality of parameters and a plurality of weights associated with the plurality of parameters.
