The purpose of the invention is to bridge the gap between parametric multi-channel audio coding and matrixed-surround multi-channel coding by gradually improving the sound of an up-mix signal while raising the bit-rate consumed by the side-information starting from 0 up to the bit-rates of the parametric methods. An aspect includes receiving a search request to locate branch prediction information associated with a branch instruction. A bumper may be integrally mounted to the hood release for resiliently contacting the grille and preventing slamming of the grille when the vehicle hood is moved from an open to a closed position. The systems and methods also enable development of relatively milder WBC reagent, suitable for assays of samples containing fragile WBCs. The estimated spatial distribution of the particles is provided in that the locations of the individual particles in a spatial distribution approximated for one other point in time are shifted dependently on how the locations of the individual particles have changed between at least two spatial distributions approximated for at least two other points in time. More particularly, it relates to devices and methods that are compliant with an inter-enterprise conversation process standard for routing electronic commerce documents between enterprises.
