Para quien usa esos instrumentos en la industria o en la salud, eso significa menos dependencia de la confianza ciega en el fabricante. Los autores detallan además cuándo el método falla, y ese límite no es un detalle menor para quien vaya a aplicarlo.","quienFirma":"Preprint enviado a Metrologia (2026); autor institucional no identificado en la fuente","confianza":"preprint","consulta":null},"sello":{"hash":"b8f3c2d6d7b881903e0c49444e19b0304026e9ebdce8a7bb1cdbb42d8b649bdd","sello":"58b5d2318bb5e564c02fe20f1d666661870ea9a33baab3615ef88760bbb67527","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6575910,"aleatorio":"ad632c470ba8c968ea920b116993e6a501688139a43318de64f5a7ea72e81de2","tiempo":"2026-10-22T22:32:00.000Z"},"nist":{"cadena":2,"pulso":1995154,"salida":"A32727015042185E787530FED53F828C26131B55C644F3F364155FFBAB02AAA2930B78FFEE6913417A86FA34480E1F05FB9B4984B59D1A0E007BB8E6E3A95F8F","tiempo":"2026-10-22T22:31:00.000Z"},"noAntes":"2026-10-22T22:32:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 22:32:22 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Companion simulation code and outputs for \"Certified de-mixing for direction-locked paired measurements: a metrological statistic with an uncertainty budget, with a ferroelectric domain-wall instantiation\"","descripcion":"<p>Reproduction package for the manuscript of the same name (submitted to Metrologia, 2026).</p> <p>Every number, table and figure in the paper is regenerated by the five self-contained Python scripts (numpy/scipy/matplotlib, seeds 20261016&ndash;20261018):</p> <p>- sim_single.py &mdash; sealing certificates, NAS identity check (10^6 draws), dictionary-misspecification leaks, single-pair suite with oracle-GLS and plug-in comparison<br>- sim_ensemble.py &mdash; full-GUM-budget coverage (68%/95%), false lock-claim rates at s=0, naive-slope dispersion statistics<br>- sim_ens3.py &mdash; the registered ensemble run quoted in Sec. 6 and Fig. 4b (best-subset load selection, BIC penalty, zero-mean and systematic load regimes, K = 2/4/8)<br>- sim_ens4.py &mdash; the unstable estimator variant documented in Appendix B (coordinate-descent limit cycles, variance inflation up to 10x)<br>- k2_figs.py","pubDate":"2026-10-20T01:44:50Z","url":"https://doi.org/10.5281/zenodo.23463157"},"indexado":"2026-10-22T22:31:26.228Z"}}
