Arithmetic methods for exploring archaeological source provenance using geochemistry – a short reply

In this reply, we respond to the comment by Pearce and colleagues regarding our recently proposed arithmetic method for assessing geochemical similarity between lithic artefacts and potential source outcrops. We thank the authors for their critique, which highlights several impor...

Epistemic Payoff Dependence: Roko's Basilisk and the Structure of Self-Referential Threats

Roko's Basilisk is a thought experiment about a future superintelligent Artificial Intelligence (AI) that punishes those who were aware of its possible creation but did not contribute to building it. Most existing analyses interpret it as a problem of decision theory or rationali...

Time Field Theory (TFT): Axiomatic Foundation, Dynamics and Classical Gravitational Tests — Version 2.0 (Perfect Circle Postulate and Periodic Self-Consistency Ontology)

This paper presents Version 2.0 of Time Field Theory (TFT), which reconstructs the entire axiomatic foundation from the kinematic level to the ontological level of periodic self-consistency and the perfect circle postulate. Starting from three core axioms of stable periodic oscil...

The MOND Acceleration Scale as a de Sitter Curvature Scale: Gauged SO(4,1) Gravity Reduces a0 = c^2 sqrt(Lambda/32pi) to a Single Free Number

Galaxy dynamics organize around an acceleration scale a0 ~ 1e-10 m/s^2 that numerically coincides with c*sqrt(Lambda) and cH0. This paper develops the hypothesis that the coincidence is structural -- that a0 is a de Sitter curvature scale, a0 = c^2*sqrt(Lambda/32pi) = (c/2)*sqrt(...

Quantitative verification of treatment delivery accuracy utilizing deep inspiration breath hold (DIBH) for left-sided breast irradiation

Abstract Purpose: To assess the treatment delivery accuracy of left-sided breast irradiation using the deep inspiration breath hold (DIBH) technique via Gamma passing rate (GPR) analysis. Methods: Thirteen patients with left-sided breast cancer who had previously undergone volume...

Comparison of TG-43 and advanced collapsed cone engine dose calculations in cervical HDR brachytherapy with plastic and metallic applicators

Abstract Purpose: Conventional brachytherapy treatment planning based on the TG-43 formalism assumes a homogeneous water medium and neglects the effects of applicator materials and tissue heterogeneities. This study aimed to investigate the clinical impact of Model-Based Dose Cal...

Comparison and Reliability of Inertial Sensor-Based Gait Data Acquisition Across Three Shank-Mounted Smartphone Configurations in Older Adults

About the Project This dataset was collected within the Spine Interactive project. The aim was to examine whether IMU time series recorded with three different smartphones are comparable during 2-minute treadmill walking trials in older adults. The devices were an iPhone 15 Pro,...

Recombination drives genome evolution in outbreak-related Legionella pneumophila isolate

Legionella pneumophila is a strictly environmental pathogen and the etiological agent of legionellosis. It is known that non-vertical processes have a major role in the short-term evolution of pathogens, but little is known about the relevance of these and other processes in envi...

Negative Dwell Times as Resolvent Derivatives: A Structural Operator-Theoretic Explanation of 𝑻𝑻=𝒕𝒈

A structural operator-theoretic account of negative group delays and post-selected excitation times in resonant atomic media. Within a scalar Lorentzian propagation model, the excitation time and the optical delay are shown to be parameter derivatives of the same frequency-resolv...

Quantum Error-Correcting Structure of Topological Vortex Logic: The [[13,7,3]]_3 CSS Family and its Algebraic Geometry

This paper establishes the algebraic and geometric structure of the [[13,7,3]]₃ ternary CSS quantum stabilizer code and its dimension-indexed family, arising from the Topological Vortex Logic (TVL) framework, developed in "Topological Vortex Logic: Stability, Root Systems, and Mo...

Mpemba Possibility Region

Uppdate: The Mpemba effect refers to the counterintuitive observation that, under certain conditions, an initially hotter water sample may freeze earlier than a colder comparison sample. Although the phenomenon has commonly been discussed in terms of evaporation, convection, diss...

[SMT-VOL10 & STCT-VOL6] THE SPECTRAL RESOLUTION OF THE BIRCH AND SWINNERTON-DYER CONJECTURE VIA SEONGGIL OPERATOR ALGEBRA

This paper completes the decalogy of the Seonggil Matrix Theory (SMT) and the hexalogy of the Seonggil Tensor Calculus Theory (STCT). We provide a rigorous resolution of the Birch and Swinnerton-Dyer (BSD) Conjecture by mapping the analytic rank of the Hasse-Weil L-function to th...

[SMT-VOL8 & STCT-VOL4] HODGE THEORETIC PHASE TRANSITIONS VIA ROUGH OPERATOR ALGEBRA: TOPOLOGICAL CONFINEMENT AND ALGEBRAIC CYCLES

The Hodge Conjecture seeks to identify the algebraic structure within the topological framework of complex projective manifolds. Traditional approaches have failed to construct algebraic cycles directly from harmonic forms due to the limitations of absolute smooth analysis. In th...

The Geometric Mechanics of 3D Space: The origin of physical motion and its mechanical proof / 3D-rymdens geometriska mekanik.

0 free parameters, 22 CODATA/PDG matches THE PROBLEM Everything humanity has ever observed exists in three dimensions (3D), yet our entire mathematical foundation rests upon a one-dimensional (1D) number line. This paper explores the hypothesis that the remaining discrepancies in...

Two Maintenance Strategies for the Human Electrochemical System: The Physical Basis of Diagnostic and Therapeutic Concepts in Traditional Chinese Medicine

The human body is a body-wide electrochemical system: cell membranes serve as capacitive units, mitochondria as energy conversion engines, autonomic nerves as regulatory wiring, and the brain as the control center with the densest low-resistance pathways carved by the history of...

Hydra-Flux — Master Compendium (Integrated Architecture)

Conventional offshore production tests of methane hydrates in unconsolidated sediments repeatedly fail due to geomechanical collapse, sand production, and unstable two-phase flow behavior during dissociation. This master compendium introduces Hydra-Flux, a conceptual modular arch...

Market opacity and fragility: Why liquidity evaporates when it is most needed

Lack of market transparency can impair the liquidity provision of non-standard liquidity suppliers and make liquidity demand increasing in illiquidity. This can yield strategic complementarities and induce multiple equilibria. Then an initial dearth of liquidity may degenerate in...

Time Field Theory (TFT) Series: Axiomatic Foundation, Physical Conceptual Structure, Classical Gravitational Tests, Black Hole Physics, Canonical Quantization, Gravitational Waves, Velocity Composition, Exact Solutions, Cosmology, Hubble Tension and Unification of Gravitation and Optics

This upload contains the complete series of academic papers on Time Field Theory (TFT), which systematically establishes a self-consistent scalar gravitational theory on flat three-dimensional Euclidean spacetime with the conservation of local intrinsic total speed as the core fi...

Time integrals under the Black-Scholes-Merton and Margrabe economies

The problem of integrating the Black, Scholes, and Merton (BSM) formula with respect to the time variable is paramount for an economist. Inspired by the real options literature, Shackleton and Wojakowski offer analytic formulae for valuing finite maturity (profit) caps and floors...
