The invention relates to compositions and methods for inhibiting sphingosine kinase and for treating hyperproliferative disease. The VoIP femtocell generally includes at least one Radio Frequency transceiver; and program logic that, at least in part, performs a broadcast channel selection protocol and a handheld reselection protocol, so as to enable one or more mobile handheld devices to select the VoIP femtocell for in-service use. The security monitoring device and the security processing system device are configured to arm and disarm based on geolocation data associated with at least one of the mobile user devices. An optical film is produced by transferring the die film. This completing may include either continuing the original link negotiation stage or restarting it.
