The Riemann Hypothesis and Yang–Mills Theory: Shared Operator Methods and Open Bridges
O comparație între estimări cu operatori pentru ipoteza Riemann și modelul Yang–Mills SU(2) pe rețea. Preprintul prezintă un certificat pentru forma aritmetică regularizată și o estimare pe rețea, apoi precizează condițiile care rămân deschise.
Abordare
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.
Domeniu și întrebări deschise
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 certificat local de pozitivitate și criterii aritmetice cu semn pentru cercetarea ipotezei Riemann, cu condiția rămasă pentru toate scările formulată explicit.
Abordare
Computer-assisted control of a complete infinite-dimensional complement, signed prime-power deficits and an explicit formula retaining all zeros.
Domeniu și întrebări deschise
The remaining all-scale condition is explicit and open. The local certificate and finite computations do not constitute a proof of the Riemann hypothesis.

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.
Abordare
Analytic calculations and synthetic spectra compare ordinary rhythm peaks, aperiodic backgrounds and detector behaviour.
Domeniu și întrebări deschise
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.
Abordare
Regularized logistic comparisons on 1,731 omission trials from an existing 34-person archive, with participant-held-out labels.
Domeniu și întrebări deschise
Outcome-blind calibration used full participant waveforms, so the reported evaluation is offline rather than a deployment simulation.

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.
Abordare
Qualifier-preserving parsing, row-level sign comparisons and comparison with a separately downloaded versioned artifact.
Domeniu și întrebări deschise
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.
Abordare
Separate reanalyses of two behavioural archives, with cross-task rank comparisons and an explicitly retrospective analysis.
Domeniu și întrebări deschise
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.
Abordare
Finite synthetic benchmarks compare a planted persistent state against five specified alternatives and test retention recovery.
Domeniu și întrebări deschise
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.
Abordare
Exact arithmetic on a finite four-value symmetry example compares a permutation orbit with uniform relation sampling.
Domeniu și întrebări deschise
The conclusions are exact for the stated finite constructions; equal density and overlap do not make the probability laws identical.

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.
Abordare
A sector- and overtone-dependent sign threshold is checked against a finite collection of computed modes.
Domeniu și întrebări deschise
The endpoint conclusion applies within windows satisfying the specified order; finite confirmation is not a result for every multipole.

Adaptive feature acquisition under diagnostic misspecification
Examines when adaptive feature acquisition helps under complementarity, redundancy and diagnostic misspecification.
Abordare
A fully specified finite Bayesian model compares a greedy conditional-information policy with an optimized static pair.
Domeniu și întrebări deschise
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.
Abordare
An executable source audit and fixed-parameter CNN comparisons separate algebraic normalization from trained accuracy.
Domeniu și întrebări deschise
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.
Abordare
Repository and original ORCA output checks reproduce selected electronic binding-energy calculations and compare their consistency.
Domeniu și întrebări deschise
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.
Abordare
A reproducible finite-spin model compares signed odd-period and Fourier diagnostics under specified perturbations and noise.
Domeniu și întrebări deschise
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.
Abordare
Published numerical summaries, estimator eligibility and code provenance are checked without reprocessing raw EEG.
Domeniu și întrebări deschise
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.
Abordare
Nondimensionalization, explicit error bounds and classical comparisons separate curve shape from absolute rate dependence.
Domeniu și întrebări deschise
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.
Abordare
A numerical audit compares the finite score table, model-label weighting and shared-label subsets.
Domeniu și întrebări deschise
The deposited scores are not independent trials. Context-associated differences do not by themselves establish a general property of models.

Model and readout dependence of radical pair yield anisotropy
Studies how radical-pair yield anisotropy depends on model conventions, reaction operators and readout.
Abordare
Historical one-nucleus conventions are separated from a newly frozen finite computational benchmark.
Domeniu și întrebări deschise
A finite observation-window maximum can be absent from the complete-yield scan. Directional contrast depends on the specified reference and noise model.
