Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Similar or slightly better tensile properties can be expected when printing PEEK in a vacuum compared to results obtained with a 150°C ambient air temperature.

    “Liu et al. [197] showed that similar or slightly better tensile properties can be expected when printing PEEK in a vacuum, compared to the results obtained with a 150 ◦ C ambient air temperature by Yang et al. [201].”
  • The rise in crystallinity shifted fracture behavior from ductile failure to brittle failure.

    “This rise in crystallinity resulted in a shift in fracture behavior, transitioning from ductile failure to brittle failure, as anticipated.”
  • Printing PEEK is challenging due to its semicrystalline nature, high melting point, and high melt viscosity.

    “However, printing PEEK can be challenging due to its semicrystalline nature, high melting point, and high melt viscosity.”
  • PEEK parts printed in the vacuum environment achieved a relative density of 99.37%.

    “The parts printed in the vacuum environment achieved a relative density of 99.37%.”
  • PEEK samples printed in a 100 MPa vacuum environment showed an improvement in crystallinity from 14.9% to 27.8%, an 86.6% increase.

    “They observed an improvement in the crystallinity of the samples, increasing from 14.9% to 27.8%, representing an 86.6% increase.”

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.
