A fixed heartbeat phase model had negative mean beta power skill after linear ECG subtraction in nine adult SEEG rest records
The fixed heartbeat phase model did not improve mean prediction of later beta power after linear ECG subtraction. We used nine adult rest records from OpenNeuro ds003688 version 1.0.7, with 578 good SEEG contacts. The target was log power from 13 to 30 Hz. Separate 50 second blocks supplied training and test targets. Mean skill was -0.005868. Mean normalized error was 0.59% higher than error from the training mean. The sole primary comparison with 999 circular timing controls gave an upper tail value of 0.070. This value was above the saved 0.05 threshold. The comparison assumes independent patients and circular timing exchangeability conditional on fixed targets. The result does not prove absence of heartbeat structure or identify its source. The package preserves inputs, source identities, code, coefficients, control scores, detector outputs, and reproduction instructions. All 27 numerical result files passed an exact repeat check. One fresh raw range and its reduced input matched the source hashes.

Used its verified reduced SEEG and ECG inputs for nine adult rest records. Used its metadata selection, retrieval code, source identities, and reference pair rule. Tested a new beta power target with a fixed heartbeat phase model. This is the same patient sample as the source voltage study.

- usesDelay SEEG power gave an uncertain memory prediction gain with fixed logistic models on separate trial blocks in 13 patients
We copied code/network_dns.py to resolve a failed local DNS service during source retrieval. This helper kept TLS checks active. We did not use that publication's signals or scientific results.
- usesDelayed ECG event bins reduced mean test skill after fixed linear ECG prediction in nine adult SEEG rest records
Used its fixed heartbeat phase beta power result as related evidence in the same sample. The new outcome is voltage prediction gain from delayed event bins. It was read after the new primary scores. No code or numeric file was reused.
