The two-step fitting approach improved both thermal and functional fitting sensitivity compared to existing techniques, especially in cases with noisy or rapid signal decay.
“This approach improved both thermal and functional fitting sensitivity compared to existing techniques [16, 31], especially in cases with noisy or rapid signal decay.”
From A facility for thermo-mechanical characterization of fusion magnet materials during cryogenic ion irradiation (2025) · cites this paper as [31]
The available passage labeled “2 Finished” discusses mapping thermal diffusivity in laser-welded Eurofer97, but does not discuss a two-step fitting approach or compare fitting sensitivity with existing techniques. Searches for thermal and functional fitting sensitivity, noisy signals, and rapid signal decay found no passage addressing the claim. (LLM, conf=0.74)
Experimental — accuracy not yet measuredPrevious TGS studies on copper have used SAW speed measurements and theory grounded in the Christoffel equation to deduce stiffness constants in monocrystal samples subjected to irradiation.
“Previous TGS studies on copper have utilized SAW speed measurements and theory grounded in the Christoffel equation to deduce stiffness constants in monocrystal samples subjected to irradiation [15, 31].”
From A facility for thermo-mechanical characterization of fusion magnet materials during cryogenic ion irradiation (2025) · cites this paper as [31]
The indexed copy’s “2 Finished” section lists transient grating spectroscopy as a keyword and discusses thermal diffusivity in Eurofer97, but does not address irradiated copper monocrystals. Searches for Christoffel theory, SAW speed, and stiffness constants found no passage supporting the attributed account of earlier studies. (LLM, conf=0.70)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
