The Riemann Hypothesis and Yang–Mills Theory: Shared Operator Methods and Open Bridges
Una comparación de estimaciones de operadores para la hipótesis de Riemann y el modelo SU(2) en red. El preprint presenta un certificado para la forma aritmética regularizada y una estimación en red, y precisa las condiciones que siguen abiertas.
Enfoque
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.
Alcance y preguntas abiertas
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 certificado local de positividad y criterios aritméticos con signo para investigar la hipótesis de Riemann, con la condición pendiente para todas las escalas formulada explícitamente.
Enfoque
Computer-assisted control of a complete infinite-dimensional complement, signed prime-power deficits and an explicit formula retaining all zeros.
Alcance y preguntas abiertas
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.
Enfoque
Analytic calculations and synthetic spectra compare ordinary rhythm peaks, aperiodic backgrounds and detector behaviour.
Alcance y preguntas abiertas
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.
Enfoque
Regularized logistic comparisons on 1,731 omission trials from an existing 34-person archive, with participant-held-out labels.
Alcance y preguntas abiertas
Outcome-blind calibration used full participant waveforms, so the reported evaluation is offline rather than a deployment simulation.

Audits the consistency of signed zeta-potential text and a numeric helper in a pinned LNP Atlas export.
Enfoque
Qualifier-preserving parsing, row-level sign comparisons and comparison with a separately downloaded versioned artifact.
Alcance y preguntas abiertas
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.
Enfoque
Separate reanalyses of two behavioural archives, with cross-task rank comparisons and an explicitly retrospective analysis.
Alcance y preguntas abiertas
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.
Enfoque
Finite synthetic benchmarks compare a planted persistent state against five specified alternatives and test retention recovery.
Alcance y preguntas abiertas
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.
Enfoque
Exact arithmetic on a finite four-value symmetry example compares a permutation orbit with uniform relation sampling.
Alcance y preguntas abiertas
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.
Enfoque
A sector- and overtone-dependent sign threshold is checked against a finite collection of computed modes.
Alcance y preguntas abiertas
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.
Enfoque
A fully specified finite Bayesian model compares a greedy conditional-information policy with an optimized static pair.
Alcance y preguntas abiertas
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.
Enfoque
An executable source audit and fixed-parameter CNN comparisons separate algebraic normalization from trained accuracy.
Alcance y preguntas abiertas
The identity reduces to normalized accuracy for every width schedule. It does not establish a sequence-specific conservation law.

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.
Enfoque
A reproducible finite-spin model compares signed odd-period and Fourier diagnostics under specified perturbations and noise.
Alcance y preguntas abiertas
Finite-window stability labels are diagnostic-dependent; the model benchmark does not establish a universal dynamical phase.

Ratio dependent response curves and the limits of quantum biological transduction claims
Reassesses whether ratio-dependent response curves identify a quantum-biological transduction mechanism.
Enfoque
Nondimensionalization, explicit error bounds and classical comparisons separate curve shape from absolute rate dependence.
Alcance y preguntas abiertas
A broad response peak is not mechanism-specific, and a fixed rate ratio need not preserve the absolute response.
