Multi-hit errors in a processor cache are detected by a multi-hit detection circuit coupled to the hit lines of the cache. The distortion generator comprises an instant controlled non-linear attenuator which utilizes the non-linear current flowing through a pair of diodes to provide the proper amount of signal attenuation over the entire frequency bandwidth. In another embodiment a bra is provided with cups that are stable in both the folded and unfolded positions wherein the cups are not self supporting. A planarization process may follow to form the final interconnect structure. In some arrangements a third checking module is provided, which checking module may be physically separated from each of said first and second checking modules. More specifically, it relates to non-steroidal monocyclic compounds, capable of rescuing the brassinosteroid receptor null mutation bri1-116.
