Analysis of anomaly characteristics in mineralized segments using core drilling and geophysical logging

Reliable recognition of mineralized intervals from borehole logging data remains difficult because weak mineralization, thin layers, borehole disturbance, and lithological changes may produce similar curve responses. This study develops a multi-parameter coupled anomaly identific...

The Yuanxian Unified Equation: A Complete Mathematical Framework Based on the T⁶⁴ Topological Ontology — On the 35-Step Dimensional-Reduction Chain, the Observer Self-Reference Term and the Physical Meaning of Five-Domain Commensuration

This paper constructs a complete mathematical framework for the Yuanxian Unified Equation, based on the core axiomatic system of Yuanxian Theory: the 64-dimensional compact torus \(T^{64}\) as topological ontology, the 35-step dimensional-reduction chain as projection mechanism,...

Exploratory Sweep Report on Jₑff: Exclusion of Spectral-Geometric Candidate Paths for the Translation Factor in the Lepton Mass Formula and a Test of the Primitivity Hypothesis — A Stage Report on the Origin of Jₑff within the 𝒯⁶⁴ Framework of Yuanxian Theory

Yuanxian Theory Core Paper No. 7, “Reading Paths of the 24 Fundamental Physical Constants” (10.5281/zenodo.22239740), has completed the structural writing of the lepton mass formula\[m_\ell = m_0 \cdot F(k) \cdot J_{\mathrm{eff}},\]where \(J_{\mathrm{eff}}\) is the translation fa...

Six Ways of Reading the Cosmic Living Organism — The Six-Consciousness Collaborative Reading Protocol for the 24 Fundamental Physical Constants

Yuanxian Theory Core Paper No. 7, “Reading Paths of the 24 Fundamental Physical Constants” (10.5281/zenodo.22239740), has recorded one by one the reading paths of the 24 constants—from the locking of the principal value of \(\alpha^{-1}\), through the still-to-be-proved status of...

Calibration of the Topological Reading Path for the Strong Coupling Constant αₛ(M_Z) — Elimination of the "Open Failure" Mark in Yuanxian Theory Core Paper No. 7 and the QCD Cross-Section Reading Protocol

In Yuanxian Theory Core Paper No. 7, “Reading Paths of the 24 Fundamental Physical Constants” (10.5281/zenodo.22239740), the entry for the strong coupling constant \(\alpha_s(M_Z)\) was the only reading path among the 24 entries that had not yet closed. This paper proposes a cali...

Topological Origin of 𝐽ₑff: From Spectral Determinant to Exploratory Closed Form

This paper demonstrates that \(J_{\mathrm{eff}}\) is not a free parameter requiring “fitting”, but a rigid reading of the \(\mathcal{T}^{64}\) topological structure on the lepton-mass cross-section. \(J_{\mathrm{eff}}\) is defined via the regularised spectral determinant of the L...

Mathematical Construction of the Normalization Factor in Yuanxian Theory and the Topologically Isomorphic Schrödinger Equation

In conventional quantum mechanics the normalization of the wave function relies on a probability interpretation imposed by an external observer. This external constraint leaves an unbridgeable logical fissure at the meta-theoretical level of modern physics. Based on the \(\mathca...

Root-style Unification: Ultimate Suture of the Six Cognitive Fault Lines by the 𝒯⁶⁴ Self-Referential Mind Field

While modern science has achieved unprecedented successes, it faces an unprecedented fragmentation: the ontological separation of mathematics and physics, the blurred boundary between quantum and classical, physical constants that depend on experimental fitting, and consciousness...

Meta-Theoretical Reconstruction of the Physics Paradigm: Ontological Demarcation and Three Explorations under the 𝒯⁶⁴ Topological Self-Referential Framework

Modern fundamental physics faces a triple meta-theoretical crisis: the “landscape problem” of string theory leads to a loss of predictivity; the quantum measurement problem leaves the identity of the “observer” unresolved; and the Gödelian limit of formal systems threatens the on...

0.618, 0.382 and −1.618: Number-Theoretic Origins, Topological Significance and Vital Pulsation of the Golden-Section Ternary Anchors — Core Foundations of the Cosmic-Vital Ontology in Yuanxian Theory

The three core constants of the equation $x^{2}+x-1=0$ — the positive root $\delta=(\sqrt{5}-1)/2\approx 0.618$, $\delta^{2}\approx 0.382$, and the negative root $-\varphi=-(1+\sqrt{5})/2\approx -1.618$ — constitute, within Yuanxian Theory, a golden-section system that unifies ma...

Electrical conductivity models for bubble-bearing marine fine-grained sediments

Abstract Large sediment-displacing bubbles are widespread in seafloors and typically found in shallow and fine-grained sediments. These bubbles have significant environmental and engineering impacts. Acoustic methods are the most widely used geophysical investigation method for b...
