An electromechanical engine valve actuation system 10 is provided including a control element 16, a first actuator 18, a second actuator 20, an armature element 26 and a motion detector 32. At least one embodiment detects a conflict among a number of data received by the router, assigns a speculative priority to one of the data in a first clock portion and sends the speculatively prioritized data to a receiving agent in a subsequent clock portion. The tile of data is then divided into quads of data that are converted into a representative element, a first delta element, a second delta element, a third delta element, and a control word. The invention further relates to screening methods for identifying agonists and antagonists of S. The solder resist protrudes outward from within the product region. Associated systems, methods, and apparatuses also are disclosed herein.
