This paper proposes an active noise control algorithm for periodic disturbances of unknown frequency. The algorithm is appropriate for the feedback case in which a single error microphone is used. A previously proposed algorithm for the rejection of sinusoidal noise sources is extended for the cancellation of multiple harmonics. Unlike many other(More)
Macrocyclic bisbibenzyls are a class of characteristic compounds, exclusively produced by liverworts. They are attracting increasing attention due to their wide range of biological activities, including antibacterial, antifungal, and antioxidative properties as well as cytotoxicity. Marchantin A is a cyclic bisbibenzyl that has previously been isolated from(More)
