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.
Vorgehen
Spectral-centroid analysis of the public PhysioNet EEGBCI and LEMON datasets, with null-model comparisons, replication and sensitivity checks.
Geltungsbereich und offene Fragen
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
Ein Vergleich von Operatorabschätzungen zur Riemannschen Vermutung und zum SU(2)-Gittermodell. Der Preprint stellt ein Zertifikat für die regularisierte arithmetische Form und eine Gitterabschätzung vor und benennt die offenen Bedingungen.
Vorgehen
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.
Geltungsbereich und offene Fragen
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
Ein lokales Positivitätszertifikat und vorzeichenbehaftete arithmetische Kriterien zur Riemannschen Vermutung, mit ausdrücklich benannter offener Bedingung über alle Skalen.
Vorgehen
Computer-assisted control of a complete infinite-dimensional complement, signed prime-power deficits and an explicit formula retaining all zeros.
Geltungsbereich und offene Fragen
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
Spektrallücken-Zertifikate für endliche Parameter und vorzeichenbehaftete Antwort im zweidimensionalen O(3)-Modell, mit expliziten Voraussetzungen und offenen Fragen für die nächste Phase.
Vorgehen
Finite-purity estimates, relative-rotor and graph-determinant analysis, and spherical elimination under stated comparison and arithmetic premises.
Geltungsbereich und offene Fragen
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.
Vorgehen
An ordered fixed-m re-expansion is compared with a finite Richardson grid of gravitational modes.
Geltungsbereich und offene Fragen
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.
Vorgehen
Participant-level signed-error contrasts, cleaning checks, bootstrap intervals and sign-flip comparisons.
Geltungsbereich und offene Fragen
A secondary-data reanalysis of an interaction already reported by the source investigators, with its own cleaning and analysis choices.
Preprint · Zenodo ·
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.
Vorgehen
Analytic calculations and synthetic spectra compare ordinary rhythm peaks, aperiodic backgrounds and detector behaviour.
Geltungsbereich und offene Fragen
Ordinary spectra can reproduce parts of the detector signature. Anchor selection alone does not identify a generating mechanism.

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.
Vorgehen
Regularized logistic comparisons on 1,731 omission trials from an existing 34-person archive, with participant-held-out labels.
Geltungsbereich und offene Fragen
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.
Vorgehen
Qualifier-preserving parsing, row-level sign comparisons and comparison with a separately downloaded versioned artifact.
Geltungsbereich und offene Fragen
The issue concerns the inspected export and helper field. It is not a general conclusion about the underlying experiments.
Preprint · Zenodo ·
Auditory distraction and report dynamics in two behavioral archives
Examines whether group auditory-distraction effects also support stable individual differences across tasks.
Vorgehen
Separate reanalyses of two behavioural archives, with cross-task rank comparisons and an explicitly retrospective analysis.
Geltungsbereich und offene Fragen
The primary cross-task rank test did not pass. Group effects and individual-difference claims remain distinct.
Preprint · Zenodo ·
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.
Vorgehen
Finite synthetic benchmarks compare a planted persistent state against five specified alternatives and test retention recovery.
Geltungsbereich und offene Fragen
One initial retention-recovery gate failed. A synthetic discrimination result does not establish a physical or biological shared state.
Preprint · Zenodo ·
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.
Vorgehen
Exact arithmetic on a finite four-value symmetry example compares a permutation orbit with uniform relation sampling.
Geltungsbereich und offene Fragen
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.
Vorgehen
A sector- and overtone-dependent sign threshold is checked against a finite collection of computed modes.
Geltungsbereich und offene Fragen
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.
Vorgehen
A fully specified finite Bayesian model compares a greedy conditional-information policy with an optimized static pair.
Geltungsbereich und offene Fragen
Results depend on the constructed worlds, observation budget and diagnostic model; they are not a universal advantage for adaptivity.
Preprint · Zenodo ·
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.
Vorgehen
An executable source audit and fixed-parameter CNN comparisons separate algebraic normalization from trained accuracy.
Geltungsbereich und offene Fragen
The identity reduces to normalized accuracy for every width schedule. It does not establish a sequence-specific conservation law.
Preprint · Zenodo ·
Reassessing copper binding in lignin inspired cluster models
Reassesses copper–lignin cluster calculations and the source lineage of earlier multivalency interpretations.
Vorgehen
Repository and original ORCA output checks reproduce selected electronic binding-energy calculations and compare their consistency.
Geltungsbereich und offene Fragen
Electronic cluster energies, solution association constants and wash retention are different observables. The calculation does not establish practical retention performance.
Preprint · Zenodo ·
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.
Vorgehen
A reproducible finite-spin model compares signed odd-period and Fourier diagnostics under specified perturbations and noise.
Geltungsbereich und offene Fragen
Finite-window stability labels are diagnostic-dependent; the model benchmark does not establish a universal dynamical phase.
Preprint · Zenodo ·
Reassessing constant claims in EEG band boundaries and their source provenance
Audits claims connecting EEG band-boundary estimates to selected mathematical constants.
Vorgehen
Published numerical summaries, estimator eligibility and code provenance are checked without reprocessing raw EEG.
Geltungsbereich und offene Fragen
Different estimators retained different participant subsets. The nearest-constant comparison depends on the estimator and aggregation.
Preprint · Zenodo ·
Ratio dependent response curves and the limits of quantum biological transduction claims
Reassesses whether ratio-dependent response curves identify a quantum-biological transduction mechanism.
Vorgehen
Nondimensionalization, explicit error bounds and classical comparisons separate curve shape from absolute rate dependence.
Geltungsbereich und offene Fragen
A broad response peak is not mechanism-specific, and a fixed rate ratio need not preserve the absolute response.
Preprint · Zenodo ·
A descriptive reanalysis of prompt context differences in the Trinity score corpus
Describes prompt-context score differences in the deposited Trinity corpus.
Vorgehen
A numerical audit compares the finite score table, model-label weighting and shared-label subsets.
Geltungsbereich und offene Fragen
The deposited scores are not independent trials. Context-associated differences do not by themselves establish a general property of models.
Preprint · Zenodo ·
Measurement and source limitations in shared constraint embedding experiments
Reassesses evidence previously described as co-reactivity to shared constraints.
Vorgehen
Pinned sources, synthetic generators, historical outputs and diagnostic definitions are reconciled.
Geltungsbereich und offene Fragen
Planted lattice structure, deterministic replay and changing multiple factors together limit the original emergence interpretation.
Preprint · Zenodo ·
Model and readout dependence of radical pair yield anisotropy
Studies how radical-pair yield anisotropy depends on model conventions, reaction operators and readout.
Vorgehen
Historical one-nucleus conventions are separated from a newly frozen finite computational benchmark.
Geltungsbereich und offene Fragen
A finite observation-window maximum can be absent from the complete-yield scan. Directional contrast depends on the specified reference and noise model.
Preprint · Zenodo ·
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.
Vorgehen
Weighted-Hilbert-space approximants retain the infinite tail through scaling, projection, transport and Mellin representations.
Geltungsbereich und offene Fragen
The reported computational campaigns are finite. An all-scale approximation or positivity obligation remains necessary.

Provides a computational audit pipeline for CuI anchoring on lignin-inspired molecular interfaces.
Vorgehen
DFT cluster calculations compare selected copper environments and molecular proxies for lignin and related interfaces.
Geltungsbereich und offene Fragen
Cluster-model energetics do not directly establish solution binding constants, wash durability or material performance.
