«It does not only govern the mass motions in the supernova core but it also imposes characteristic signatures on the neutrino and gravitational - wave emission, which will be measurable for a future Galactic supernova. (sciencedaily.com)
SM's chart grouping runs by model is pretty telling: each model produces a very characteristic signature, tightly clustered. (deepclimate.org)
The carbon contained in the zircon has a characteristic signature — a specific ratio of carbon - 12 to carbon - 13 — that indicates the presence of photosynthetic life. (sciencedaily.com)
