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?

  • Owing to interactions expressed in Schrödinger's equation among many degrees of freedom, the amount of y-disjointness in supports of Φ and Ψ⊥ will typically tend to increase dramatically as time goes on, with more and more degrees of freedom participating.

    “In fact, owing to the interactions-expressed in Schr¨ odinger's equation-among the many degrees of freedom, the amount of y-disjointness in the supports of Φ and Ψ ⊥ will typically tend to increase dramatically as time goes on, with, as in a chain reaction, more and more degrees of freedom participating in this disjointness (see [13,42,64,38]; see also [ 12 ])).”

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.
