Diffusion damping thus damps temperature and density anisotropies in the early universe. Four- or five-octave models usually have a damper pedal that sustains or damps the sound. This design cushions the impacts of landing and damps out vertical oscillations. When the key is released, the yarn damps the vibration of the string. The system as described damps out fluctuations in temperature. The wave is transient (quickly damps out). NLRP3 is activated by cellular events induced by different PAMPs and DAMPs stimuli. Other important DAMPs, characteristic for ICD are secreted HMGB1 and ATP. Many receptors for MAMPs (and DAMPs) have been discovered. Nearly 640,000 tons of plastic gears damps the oceans every year. At the beginning, there is a binding of collectin to PAMPs or DAMPs. In the canonical inflammasome pathway, PAMPs and DAMPs are recognised by certain endogenous PRRs. Examples of non-protein DAMPs include ATP, uric acid, heparin sulfate and DNA. They describe these ancient signals as danger-associated molecular patterns, or DAMPs. For instance, necroptotic cells release highly immunogenic DAMPs, initiating adaptive immunity.
