Golden ratio organization in human EEG is associated with theta-alpha frequency convergence: a multi-dataset validation study

Studies the association between theta–alpha frequency organization and convergence near the 8 Hz boundary in resting-state human EEG.

Approccio

Spectral-centroid analysis of the public PhysioNet EEGBCI and LEMON datasets, with null-model comparisons, replication and sensitivity checks.

Ambito e domande aperte

An observational association in the analysed datasets. It does not establish a causal mechanism or a universal organizing law.

The Riemann Hypothesis and Yang–Mills Theory: Shared Operator Methods and Open Bridges

Un confronto tra stime di operatori per l’ipotesi di Riemann e il modello SU(2) su reticolo. Il preprint presenta un certificato per la forma aritmetica regolarizzata e una stima su reticolo, e indica le condizioni ancora aperte.

Approccio

The manuscript keeps equality modes, signed responses and complete tails in their respective operator formulations. The latest revision treats a regularized arithmetic form at a specified cutoff and a family of SU(2) lattice parameters.

Ambito e domande aperte

A zero-tolerance sign bound along an unbounded sequence of cutoffs remains open. The lattice analysis leaves a conditional comparison to prove and a separate passage to the continuum with uniform decay in physical time. The paper is a preprint.

Local Weil Positivity and Signed Prime-Deficit Criteria

Un certificato locale di positività e criteri aritmetici con segno per studiare l’ipotesi di Riemann, con la condizione ancora aperta su tutte le scale indicata esplicitamente.

Approccio

Computer-assisted control of a complete infinite-dimensional complement, signed prime-power deficits and an explicit formula retaining all zeros.

Ambito e domande aperte

The remaining all-scale condition is explicit and open. The local certificate and finite computations do not constitute a proof of the Riemann hypothesis.

Spectral-gap certificates and signed response for the two-dimensional O(3) model

Certificati di gap spettrale a parametri finiti e risposta con segno nel modello O(3) bidimensionale, con premesse esplicite e domande aperte per la fase successiva.

Approccio

Finite-purity estimates, relative-rotor and graph-determinant analysis, and spherical elimination under stated comparison and arithmetic premises.

Ambito e domande aperte

Results concern this two-dimensional model and the stated regimes. They do not establish a four-dimensional Yang–Mills mass gap.

Azimuthal finite-difference identities for the slow-spin leading-eikonal Kerr damping rate

Derives azimuthal finite-difference identities for slow-spin Kerr quasinormal-mode damping within the leading-eikonal expansion.

Approccio

An ordered fixed-m re-expansion is compared with a finite Richardson grid of gravitational modes.

Ambito e domande aperte

The identities retain their specified spin and eikonal order; numerical agreement is a finite-regime diagnostic.

Sound timing and visual reports in a public behavioral dataset

Reanalyses whether sound timing changes visual reports in an existing public behavioural dataset.

Approccio

Participant-level signed-error contrasts, cleaning checks, bootstrap intervals and sign-flip comparisons.

Ambito e domande aperte

A secondary-data reanalysis of an interaction already reported by the source investigators, with its own cleaning and analysis choices.

Ordinary spectra can mimic a Schumann anchored golden ratio enrichment pattern

Tests whether a preferred frequency anchor uniquely identifies golden-ratio organization in EEG-like spectra.

Approccio

Analytic calculations and synthetic spectra compare ordinary rhythm peaks, aperiodic backgrounds and detector behaviour.

Ambito e domande aperte

Ordinary spectra can reproduce parts of the detector signature. Anchor selection alone does not identify a generating mechanism.

Preprint · Zenodo ·

Limited incremental prediction of cardiac synchrony judgments from heartbeat locked scalp activity

Asks whether heartbeat-locked scalp features improve prediction of later cardiac synchrony judgments beyond other covariates.

Approccio

Regularized logistic comparisons on 1,731 omission trials from an existing 34-person archive, with participant-held-out labels.

Ambito e domande aperte

Outcome-blind calibration used full participant waveforms, so the reported evaluation is offline rather than a deployment simulation.

Preprint · Zenodo ·

Signed zeta potential in the LNP Atlas website export

Audits the consistency of signed zeta-potential text and a numeric helper in a pinned LNP Atlas export.

Approccio

Qualifier-preserving parsing, row-level sign comparisons and comparison with a separately downloaded versioned artifact.

Ambito e domande aperte

The issue concerns the inspected export and helper field. It is not a general conclusion about the underlying experiments.

Auditory distraction and report dynamics in two behavioral archives

Examines whether group auditory-distraction effects also support stable individual differences across tasks.

Approccio

Separate reanalyses of two behavioural archives, with cross-task rank comparisons and an explicitly retrospective analysis.

Ambito e domande aperte

The primary cross-task rank test did not pass. Group effects and individual-difference claims remain distinct.

Identifying a persistent shared state in a synthetic intervention benchmark

Defines an operational signature for a persistent shared state using delayed influence, erasure and address specificity.

Approccio

Finite synthetic benchmarks compare a planted persistent state against five specified alternatives and test retention recovery.

Ambito e domande aperte

One initial retention-recovery gate failed. A synthetic discrimination result does not establish a physical or biological shared state.

Exact finite comparisons of a symmetry orbit and uniform binary constraint relations

Tests how the sampling law of a random constraint relation affects joint inclusion and second moments.

Approccio

Exact arithmetic on a finite four-value symmetry example compares a permutation orbit with uniform relation sampling.

Ambito e domande aperte

The conclusions are exact for the stated finite constructions; equal density and overlap do not make the probability laws identical.

Preprint · Zenodo ·

Finite-multipole damping order and endpoint selection in Schwarzschild quasinormal-mode pairs

Studies how finite-multipole Schwarzschild damping approaches its leading-eikonal limit and selects pairwise endpoints.

Approccio

A sector- and overtone-dependent sign threshold is checked against a finite collection of computed modes.

Ambito e domande aperte

The endpoint conclusion applies within windows satisfying the specified order; finite confirmation is not a result for every multipole.

Preprint · Zenodo ·

Adaptive feature acquisition under diagnostic misspecification

Examines when adaptive feature acquisition helps under complementarity, redundancy and diagnostic misspecification.

Approccio

A fully specified finite Bayesian model compares a greedy conditional-information policy with an optimized static pair.

Ambito e domande aperte

Results depend on the constructed worlds, observation budget and diagnostic model; they are not a universal advantage for adaptivity.

Accuracy retention and width allocation at fixed parameter count: A reproducibility correction to The φ-Compression Law

Corrects the interpretation of an efficiency-retention identity previously attributed to golden-ratio network widths.

Approccio

An executable source audit and fixed-parameter CNN comparisons separate algebraic normalization from trained accuracy.

Ambito e domande aperte

The identity reduces to normalized accuracy for every width schedule. It does not establish a sequence-specific conservation law.

Reassessing copper binding in lignin inspired cluster models

Reassesses copper–lignin cluster calculations and the source lineage of earlier multivalency interpretations.

Approccio

Repository and original ORCA output checks reproduce selected electronic binding-energy calculations and compare their consistency.

Ambito e domande aperte

Electronic cluster energies, solution association constants and wash retention are different observables. The calculation does not establish practical retention performance.

Finite window diagnostics and noise channels in a kicked Ising chain

Distinguishes dynamical responses that receive the same finite-time return label in a kicked Ising chain.

Approccio

A reproducible finite-spin model compares signed odd-period and Fourier diagnostics under specified perturbations and noise.

Ambito e domande aperte

Finite-window stability labels are diagnostic-dependent; the model benchmark does not establish a universal dynamical phase.

Reassessing constant claims in EEG band boundaries and their source provenance

Audits claims connecting EEG band-boundary estimates to selected mathematical constants.

Approccio

Published numerical summaries, estimator eligibility and code provenance are checked without reprocessing raw EEG.

Ambito e domande aperte

Different estimators retained different participant subsets. The nearest-constant comparison depends on the estimator and aggregation.

Ratio dependent response curves and the limits of quantum biological transduction claims

Reassesses whether ratio-dependent response curves identify a quantum-biological transduction mechanism.

Approccio

Nondimensionalization, explicit error bounds and classical comparisons separate curve shape from absolute rate dependence.

Ambito e domande aperte

A broad response peak is not mechanism-specific, and a fixed rate ratio need not preserve the absolute response.

A descriptive reanalysis of prompt context differences in the Trinity score corpus

Describes prompt-context score differences in the deposited Trinity corpus.

Approccio

A numerical audit compares the finite score table, model-label weighting and shared-label subsets.

Ambito e domande aperte

The deposited scores are not independent trials. Context-associated differences do not by themselves establish a general property of models.

Measurement and source limitations in shared constraint embedding experiments

Reassesses evidence previously described as co-reactivity to shared constraints.

Approccio

Pinned sources, synthetic generators, historical outputs and diagnostic definitions are reconciled.

Ambito e domande aperte

Planted lattice structure, deterministic replay and changing multiple factors together limit the original emergence interpretation.

Model and readout dependence of radical pair yield anisotropy

Studies how radical-pair yield anisotropy depends on model conventions, reaction operators and readout.

Approccio

Historical one-nucleus conventions are separated from a newly frozen finite computational benchmark.

Ambito e domande aperte

A finite observation-window maximum can be absent from the complete-yield scan. Directional contrast depends on the specified reference and noise model.

Complete-tail projections and finite multiscale experiments for a discrete Riemann hypothesis criterion

Develops complete-tail projection identities and finite multiscale diagnostics for a discrete Riemann-hypothesis criterion.

Approccio

Weighted-Hilbert-space approximants retain the infinite tail through scaling, projection, transport and Mellin representations.

Ambito e domande aperte

The reported computational campaigns are finite. An all-scale approximation or positivity obligation remains necessary.
