A semiconductor structure includes a first substrate portion having a surface and a first active region disposed in the first substrate portion. The first member defines a receptacle for receiving teeth located on either of the user’s upper or lower jaw, and a first plurality of fasteners on an opposite side and extending outwardly therefrom. The method takes advantage of the non-stationary Point Spread Function of a non-parallel hole collimator to determine depth information of gamma events emitted from the ROI. The post, the inner body, and the compression sleeve are movable with respect to the outer body between a first position in which the connector is not mounted to an equipment port and a second position when the connector is mounted to the equipment port. One useful application of the present invention is in Internet FTP servers to log and track utilization of the server resources by the IP address of the computing device that initiates each FTP session. In the case where an erasing power when erasing a record mark at a linear velocity v1 is Pe1, a recording power when forming the record mark at the linear velocity v1 is Pw1, an erasing power when erasing the record mark at a linear velocity v2 faster than v1 is Pe2, and a power when forming the record mark at the linear velocity v2 is Pw2, a relationship of Pw1Pe1>Pw2Pe2 is satisfied.
