The present invention relates to systems for communicating with synchronous devices, in particular, to automatic test equipment for memory device testing and, more specifically, to a test system for testing a high-speed synchronous memory device using DQS signals obtained from the memory device to achieve the precise fault strobe timing characteristics. The amorphous diamond material having a hardness that is at least 20 GPa and less than 45 GPa and a modulus that is at least 150 GPa and less than 400 GPa. In people with normal body weight, fnglyLTF stabilizes and protects leptin, a hormone with powerful effects on fat metabolism and body mass. A trial neurostimulation period is generally desired to evaluate the efficacy of the therapy.
