This paper proposes that the Sun's interior organizes into a hierarchy of turbulence 'closure regimes' — zones where plasma behaves differently depending on how well energy cascades are constrained. For fusion, the interest is indirect: the same mathematical classification of partial-closure turbulence could inform how we model turbulent transport in magnetically confined plasmas, where similar regime boundaries exist. The work is purely theoretical and unreviewed, so claims should be treated as exploratory rather than validated.

Physics-Informed Neural Networks (PINNs) struggle to resolve sharp boundaries — like the interfaces between phases or the steep gradients at plasma-facing surfaces — because standard sampling misses these narrow regions. This paper introduces an adaptive sampling strategy that directs training attention to the most numerically difficult zones using the network's own gradient information, outperforming residual-based methods. If generalized, this technique could improve PINN-based solvers for fusion plasma turbulence simulations, where sharp gradient layers are a persistent challenge.

Using high-speed laser imaging in a combustion engine, this study finds that the spatial position of a large-scale vortex at ignition time — not just turbulent flame speed — most strongly determines combustion timing variation cycle-to-cycle. The relevance to fusion is methodological: time-resolved PIV and LIF diagnostics for turbulent flow validation are also used to benchmark plasma turbulence codes, and the finding that large-scale flow structures dominate over local turbulence intensity echoes debates in tokamak transport modeling. The combustion context limits direct applicability.

This paper claims to derive gravity, the strong nuclear force, and electromagnetism from a single rule — nearest-neighbor attraction between discrete 'field quanta' on a lattice — validated through 225 numerical simulations. Deep analysis flags the methodology as qualitative rather than quantitatively predictive, with no benchmarking against established physics, no code or data deposited, and low reproducibility. Its relevance to fusion is negligible; it is included only because the pipeline scored it against turbulence-modeling and plasma-disruption roadblocks at low confidence.

This mathematics paper applies bifurcation theory to a variant of the nonlinear Schrödinger equation with fractional (M-truncated) derivatives, identifying classes of wave solutions and their sensitivity to parameter changes. Nonlinear Schrödinger-type equations appear in plasma physics to model wave propagation and instabilities, making the mathematical tools here of potential indirect use. The paper's connection to fusion is weak and speculative — no plasma application is made explicit by the authors.

This paper proposes a semi-empirical formula to predict atomic radii (Z=1 to 95) and X-ray spectra to within roughly 0.6–2% accuracy using a fitted equilibrium condition. Accurate atomic data underpins plasma spectroscopy used to diagnose impurity content in fusion devices, but this work is unreviewed, lacks reproducible code or data, and uses unresolved reference citations. Its relevance to plasma-wall interactions is at most peripheral.

Using density functional theory, this study characterizes CsLi2Bi as a topological material with band inversion and Dirac-like electronic features, reporting its optical and thermodynamic properties. The pipeline flagged this against tritium-breeding at low confidence (0.30), possibly because lithium compounds are candidate tritium-breeding blanket materials. However, CsLi2Bi's topological electronic properties are not directly relevant to tritium production or retention; the connection is tenuous.

This paper validates a Lattice Boltzmann Method (LBM) solver for conjugate heat transfer — simultaneously modeling fluid cooling and solid conduction — against experimental benchmarks for forced and natural convection. Divertor components in fusion reactors face extreme combined heat loads where such multi-physics thermal solvers are needed for engineering design. The benchmarking results are promising for industrial applications, though the paper does not address fusion-relevant conditions (e.g., plasma heat fluxes of 10–20 MW/m²).

This is a minor software release record for TaylorSeries.jl, a Julia package for Taylor polynomial arithmetic, adding an allocation-free matrix multiplication function. Fusion relevance is minimal; the pipeline scored it against turbulence-modeling at 0.30 because Taylor series methods appear in some plasma simulation codes. This is a routine software maintenance update, not a research paper.

This preprint applies an alternative gravity theory (CCEGA) to predict a maximum neutron star mass of 4.26 solar masses, substantially higher than General Relativity's prediction of 1.52–2.26 solar masses, arguing recent pulsar observations favor CCEGA. The pipeline scored this against first-wall-materials at 0.20, which appears to be a spurious connection — neutron star equations of state are not relevant to fusion wall material selection. Included here only to complete the required 10 entries; its fusion relevance is effectively zero.
