The present invention provides a novel compound that is structurally similar to curcumin and has a suppressive effect on A\u03b2 aggregation, a degradative effect on A\u03b2 aggregates, an inhibitory effect on \u03b2-secretase, and a protective effect on neurons. The serial data bits are divided by a predetermined pattern among the frequency bands providing frequency diversity. Efficient and reliable data transfer is provided by a system incorporating broadcast and point-to-point communication topologies. Each rotating wheel includes a body and a rod extending through the body. The interactive assistant provides feedback analytics via the set-top box based on the communications between the subscriber and the interactive assistant, the diagnostic data log and the diagnostic report.
