The present invention relates to a system and method for providing a communication network. Generally, the imprint compositions comprise a matrix material defining an imprint of a template molecule, and the template molecule typically corresponds to a portion of a macromolecule of interest. The saddle allows the towed truck to face forward during transport, thus allowing for the normal loads and stresses of movement on the towed truck. For each predictee field in the topological order, a transformed field is then computed via the relationship between predictor and predictee in the optimum relational dependency transform.
