Neither has a standard test been established for evaluating the acoustics of the intact instrument.

متن کاملSelf-sustaining autocatalytic networks within open-ended reaction systems
Given any finite and closed chemical reaction system, it is possible to efficiently determine whether or not it contains a ‘self-sustaining and collectively autocatalytic’ subset of reactions, and to find such subsets when they exist. However, for systems that are potentially open-ended (for example, when no prescribed upper bound is placed on the complexity or size/length of molecules types), ...
