The present invention concerns compositions and methods for the treatment of disorders characterized by the over-expression of an LIV-1. Thus, a communication with the IPv4 terminal can be executed without preliminarily fixedly allocating the IPv4 address to the IPv6 terminal. In an embodiment, the two models correspond to black box and interface timing models. The UE also determines to use multiple groups of one or more cells. Rotation of the test mass about its center of mass during freefall changes the path length of the oppositely reflected light beams by equal amounts, thereby achieving common mode cancellation of the effects of test mass rotation when the two reflected light beams are interferometrically combined.
