This paper introduces an alternative, deterministic paradigm for the micro-world by modeling the hydrogen atom as an open, non-linear dissipative system embedded within the hydrodynamic substratum of Wheeler’s quantum foam. By replacing the abstract complex-valued wave function of standard quantum mechanics with a modified three-dimensional Van der Pol system formulated via Hamilton’s quaternions (H), we resolve the fundamental paradoxes of stationarity, instantaneous quantum jumps, and wave-particle duality. In this framework, the stable ground state of the atom emerges naturally as a stable limit cycle (attractor), where the classical Coulomb potential acts as an active negative-friction energy pump that balances velocity-dependent radiative dissipation at the Bohr radius (a0). We present a non-quantum, electrodynamic derivation of the Bohr radius and link the emission frequency directly to radiation intensity via the characteristic impedance of free space (Z0) without invoking Planck’s constant (h). Furthermore, the four traditional quantum numbers (n, l, m, s), the Zeeman splitting, and the Pauli exclusion principle are decoded as explicit geometric and topological properties of a phase-locked spatial rotator, bypassing the necessity of both the Schrödinger probability density and the complex Dirac matrices.

For the majority of its existence, our species did not live in settlements, did not have agriculture, writing or metallurgy. These are all features of the Holocene Epoch, and the global human population during most of the time since the start of that epoch remained both low and relatively constant until the beginning of the 19th Century, accelerating through the 20th Century, following the Industrial and Agrarian Revolutions. The enormous population, and the complex, planet-wide capitalist technological civilisation on which they depend, but which also exploits them, are now faced with numerous dangers, which are likely to prove insuperable.

Graph theory plays a vital role in the study of mathematical structures and their applicationsin communication networks, optimization, and computer science. Among the variousdomination parameters, the Double Roman Domination Number has attracted significant attentiondue to its enhanced defensive strategy compared with classical domination concepts.This paper investigates the Double Roman Domination Number of Degree-Centric Graphsobtained from several standard graph families. The degree-centric transformation is firstconstructed for each graph, and the corresponding Double Roman Domination Numbers aredetermined. Based on these results, general observations and formulas are established fordifferent classes of graphs, illustrating the relationship between the degree-centric transformationand the domination parameter. The obtained results extend the study of dominationin transformed graphs and provide a foundation for future research in degree-centric graphtheory.

Discrete-valued neural networks have attracted increasing attention because they require less memory and lower computational cost than conventional floating-point neural networks. While discrete weights are often obtained by quantizing pretrained continuous-valued networks, such approaches are not applicable to reinforcement learning tasks that cannot be trained by gradient-based methods. This paper investigates the training of multilayer perceptrons (MLPs) with ternary connection weights {−1,0,1} using Genetic Algorithm (GA) for the Atari Space Invaders reinforcement learning task. The performance of ternary-weight networks is compared with that of binary-weight networks {−1,1} under identical network topologies and GA configurations. Experimental results show that GA configuration employing a smaller population size and a larger number of generations significantly outperforms a configuration with a larger population size and fewer generations when the total number of fitness evaluations is fixed. Furthermore, no statistically significant difference is observed between ternary and binary weight representations in terms of game performance. Although ternary weights exhibit slightly better median and worst-case performance, binary weights occasionally achieve higher best scores while requiring less memory. These findings suggest that binary-weight neural networks provide an attractive trade-off between performance and memory efficiency, making them an attractive representation for evolutionary reinforcement learning.

It is argued that the known physical fields themselves can be comprehended as extra dimensions attached to spacetime. This is achieved by copying the basic structure of Special Relativity related to objects, and pasting it at the level of fields. The role of the conversion factor played by the velocity of light there is played by Newtons constant here. This leads to a permutation of the roles of established concepts.

This paper is the presentation of the 2007-2026 Planck scale informational physical model, which is based on philosophical "The Information as Absolute" concept, which was formulated mainly in 2007. In the concept it is rigorously proven that nothing exists besides some informational patterns/systems of the patterns that are elements of the absolutely fundamental, and absolutely infinite, "Information" Set. Thus Matter for sure is nothing else than some informational system of informational patterns/sub-systems — particles, fields, bodies, etc. The other fundamental base of the model is the outstanding findings of von Weizsäcker and Fredkin-Toffli, who proved that Matter is based on some binary logics ("UR hypothesis"), and that if a system consists of reversible elements, then this system doesn’t dissipate energy outside, whereas the conception above makes these findings as completely natural. That allowed to define scientifically a number of fundamental phenomena/notions, first of all "Space", "Time", "Matter", "Energy", "Inertia", and so to solve, or essentially to clarify, a number of fundamental physical problems, considering everything in Matter as some specific disturbances in Matter’s ultimate base — dense lattice of fundamental logical elements (FLE) that is placed in real Matter’s (here utmost universal "kinematical") [5]4D spacetime) — what are particles and antiparticles, what are physical senses of basic equations ib kinematics, first of all of Lorents transformations and in dynamics., etc.

This note proposes a path toward knot-like organized structure in an Adaptive Medium (AM): a recursively adapting field whose local state responds to both external drive and its own neighbourhood. Within that Medium, microscopicvibrational degrees of freedom can phase-lock on steep density slopes into compact, particle-like cohorts. Cohort emission leaves a local vacancy; that vacancy is filled by vacancy backfillfrom the cell behind the shot (opposite the emission direction). Backfill steepens the upstream face, so emission regenerates andthe active lip retreats into remaining dense fuel—a kickback cascade—until a weaker valley brakes the process. Cohorts, wakes, and cascades are presented as the dynamical bridge from a continuous Adaptive Medium toward string- and knotlike organization. The account is conceptual and illustrated by interactive GPU simulations; it is not offered as a closed continuum theorem.

The Initial Entropy Problem asks why the early universe began in an exceptionally low gravitational entropy state despite matter and radiation being at thermal equilibrium. Standard cosmology accepts Penrose's Past Hypothesis as a brute empirical fact, without a dynamical mechanism that enforces it. This paper presents a candidate Center Origin White Hole Cyclic Cosmology, built from thirteen explicit axioms, offered as an axiomatic framework, not a resolution of the problem it addresses. The model proposes that the Big Bang is the time-reversed quantum-gravity bounce of a single, monolithic universal black hole. Three axioms carry the model's real explanatory weight and are flagged plainly rather than hidden in notation: Axiom 9 stipulates an explicit exception to the Second Law of Thermodynamics at the transition; Axiom 11 stipulates repulsive anti-gravity that cannot be derived from time-reversal of the Einstein field equations and is grounded only in current untestability; Axiom 13 stipulates that dark energy is dynamical rather than a true cosmological constant, an explicit, falsifiable bet on an open question in dark energy research that current measurements do not support under a constant &Lambda. The paper derives the model's recollapse dynamics as an exact consequence of the Friedmann equation for a dust-dominated closed universe and shows explicitly where this derivation fails to match a universe dominated by dark energy. The framework does not derive low initial entropy from more fundamental principles; it relocates the Past Hypothesis to a named, falsifiable transition.

Gravitational waves in the microhertz regime represent an unexplored window into slow dynamical processes in planetary interiors and the longu2011period tidal interactions within the Solar System. Jupiter, whose rotation period of 9.925 h is known with high precision, should generate a gravitational wave near 55.97 $mu$Hz if its mass distribution departs from perfect axial symmetry. Such a signal is far below the sensitivity of existing gravitationalu2011wave detectors and is strongly Doppleru2011shifted by the synodic Earth—Jupiter motion, making direct detection challenging.Using 20 years of barometric pressure data from DWD stations, we extract Jupiter’s gravitational wave through coherent demodulation of the phase modulations induced by Earth’s orbit and by the four Galilean moons. The recovered carrier frequency exhibits SNR $approx100$ and reveals a previously unknown longu2011term frequency drift associated with Jupiter’s deep interior. The modulation indices and phases of Io, Europa, Ganymede, and Callisto are stable across 752 independent realizations, demonstrating that Earth’s atmosphere responds coherently to microhertz gravitational forcing.The measured modulation indices exceed linearized Doppler predictions by a factor of 12.7, implying a propagation speed of $vapprox 0.08 c$ for the wave along the Jupiter—Earth path. Because this path lies entirely within the Sun’s gravitational potential, our results suggest that microhertz gravitational waves may experience dispersive propagation in strongly curved spacetime. No additional longu2011term phase modulations were detected. These findings open a new observational channel for studying gravitational phenomena in the Solar System at ultrau2011low frequencies.

The Cosmological Special Theory of Relativity (CSTR) re-derives the Lorentz transformation, relativistic quantum mechanics, quantumfield theory, and general relativity within a cosmological inertial frame, in which a local, unexpanded spatial coordinate is related to thephysically expanded coordinate of a Robertson-Walker universe through a cosmological expansion function τ (t0) (Yi, 2020, 2025). Fivecompanion reviews have each examined a different sector of this program — special-relativistic kinematics, relativistic quantum mechanics andfield quantization, the Cosmological General Theory of Relativity’s black-hole solutions, the group-theoretic structure of the transformationitself, and the theory’s observational status — and each has found that CSTR’s predictions reduce, in a precise and recurring sense, tothose of the corresponding standard theory. This paper collects that recurring correspondence into a single, systematic set of comparisontables, juxtaposing every principal CSTR equation against its special-relativistic, quantum-mechanical, quantum-field-theoretic, or generalrelativisticcounterpart, and identifies the single limit — evaluation at a fixed cosmological epoch, equivalently τ (t0) → const — responsiblefor every instance of correspondence. We further collect, in a final comparison, the specific respects in which CSTR is not merely a relabelingof standard theory: the multi-epoch groupoid structure and the associated open questions identified in a companion review. The result isintended as a single reference synthesizing the correspondence structure of the entire CSTR program.

Galactic rotation-curves shows in many spiral- and dwarfgalaxies deviations in movement from the expectation of baryonic matter alone. Usually these deviations are explained by supposing a domination of a "dark-matter" halo. Here, in this treatise an alternative scenario is discussed in the sense of Ockams Razor: not to speculate new things to safe the phenomena but to try an explanation of observed phenomena by very well-known contributions. Therefore a global galactic magnetic plasma-halo is able by supposing a magnetic pressure and stress-term to deliver an additional dynamical term to movement of stars. This model doesn’t substitute gravity but elaborates the eeffective dynamics by magnetohydrodynmical effects (MHD).

By interpreting inertia and gravity in terms of both classical electrodynamics and hydrodynamics, novel and accurate formulae for inertia, gravity and the gravitational constant can be derived from a Higgs field with precise geometric properties. Extending these formulae to general relativity, it is shown that the speed of light, the vacuum energy density, the cosmological constant, and 4-dimensional space-time curvature can also be derived from the same assumptions. A new model of general relativity and universal expansion based on a dynamically oscillating space-time is proposed.

A long-standing puzzle in plasma physics is the universally fast rate of magnetic reconnection, observed to be of order 0.1 across diverse environments yet unexplained by classical resistive magnetohydrodynamics (MHD). We propose a new analytical model for two-dimensional steady-state reconnection based on two concepts: the magnetic moment force as the gyro-averaged Lorentz force, and the semi-free electron constraint arising from quasi-neutrality. We show that the inflow is driven by the magnetic moment force rather than resistive diffusion, while the outflow is governed by the ion pressure gradient. The model yields a closed-form reconnection rate that depends only on the electron-to-ion temperature ratio and ion charge state, independent of system size, field strength, density, and resistivity. For a thermal equilibrium hydrogen plasma, the rate is approximately 0.2, consistent with satellite observations and simulations. The model also reproduces the bipolar electrostatic field at the current sheet center. Compared with Sweet-Parker, Petschek, and Hall-MHD models, our framework offers a first-principles kinetic explanation for the universal reconnection rate. Finally, we propose a corresponding modification to the two-fluid MHD equations, removing the electron pressure gradient and replacing the Lorentz force with the magnetic moment force.

An axiomatic framework for the temporal structure of quantum pure states is formulated. In addition to time-reversal symmetry, two ontological postulates are introduced: binary reality and coherent composition. A physically complete pure state is required to contain two distinct time-reversal-related branches with a definite relative phase. We prove that, for a time-reversal-covariant Hamiltonian, the reversed branch obtained by applying the antiunitary time-reversal operator to the time-reflected forward solution satisfies the same Schrödinger equation. Linearity and coherent composition then imply a coherent superposition of the two partners. The theorem does not require different energy eigenvalues: the partners may lie in the same degenerate eigenspace. The result is therefore a conditional theorem of the enlarged axiomatic framework rather than a derivation of quantum superposition from standard time-reversal symmetry alone.

For centuries, the existence of a Perfect Cuboid—an Euler Perfect Box where the three edges, three face diagonals, and the internal space diagonal are all positive integers—has remained one of the most resilient open challenges in number theory. This manuscript delivers a definitive proof establishing the absolute non-existence of such a system. By decomposing the structural framework into three exhaustive geometric classes (scaloid, isosceles, and equilateral), we implement an original polynomial transformation to isolate unbreakable irrationality barriers. We demonstrate that the arithmetic parameters governing the system are mutually exclusive across all integer domains, proving that an Euler Perfect Box is structurally impossible.

Person Re-Identification (ReID) under severe occlusion remains a formidable challenge, primarily because existing discriminative models lack the capacity to infer missing topological structures, inevitably leading to fragmented feature representations and compromised metric spaces. To break this perceptual limitation, we propose a novel end-to-end Diffusion-Driven Dual-stream Framework ($text{D}^3text{F}$), which seamlessly integrates generative structural priors from Diffusion Transformers (DiT) into vision-language ReID. To overcome the high computational overhead and semantic gaps inherent in diffusion models, we first design a truncated prior extraction mechanism alongside a Cascaded Inverted Modality Shuffle Network (CIMSN) to achieve lightweight and deep cross-modal interaction. Furthermore, recognizing that divergent generative features can severely contaminate the strict distance metric space, we propose an Asymmetric Decoupled Feature Guidance (ADFG) strategy. ADFG strictly utilizes the fused generative prior as a contextual lens to update text prompts, while reverting to pure discriminative features for mask localization and final metric pooling. This restrained decoupling strategy strikes an optimal balance between occlusion-resistant inference and metric space purity. Extensive experiments demonstrate that the proposed $text{D}^3text{F}$ significantly outperforms existing methods, achieving state-of-the-art (SOTA) performance on both occluded and holistic ReID benchmark datasets.

This work presents the first application of the Dark Matter by Quantum Gravitation (DMbQG) theory to the study of dark matter (DM) at cosmological scales. In Section 2.1, the first Friedmann equation is introduced within the DMbQG framework. A key feature of this approach is the explicit separation between baryonic matter density and dark matter density. It is shown that, in this theory, the dark matter density evolves with the cosmological scale factor, a, following a power-law exponent of −2.5, in contrast to the ΛCDM model, where total matter density is not differentiated and scales as a with exponent -3.In Section 2.2, the second Friedmann equation and the cosmological conservation equation are presented. From the latter, the equation-of-state parameter w is derived for baryonic matter, dark matter, and dark energy. A novel result of this work is that, for dark matter, w = −1/6, which implies that its effective density is one-half of its physical density.In Section 3, the age of the Universe is calculated first within the standard ΛCDM model and subsequently using the DMbQG framework. A central result is that the age integral obtained with DMbQG is approximately 11.5% larger than that derived from ΛCDM. This difference allows for consistency with the Hubble constant measured by the SHOES project, based on Type Ia supernovae in the local Universe, with Hu2080 = 73 km/s /Mpc, yielding an age of 14.7 Gyr. In contrast, applying this same value within ΛCDM leads to an age of 12.8 Gyr, in tension with the oldest known astrophysical objects. Consequently, ΛCDM relies on the Planck Collaboration value, Hu2080 = 67.4 km/ s/Mpc, which gives an age of 13.85 Gyr.Given that the SHOES method provides a more direct measurement of the present-day expansion rate, while the Planck value is inferred from early-Universe data (cosmic microwave background), the former may better represent the current Hubble parameter. The Hubble tension remains one of the major open problems in cosmology, and this work suggests that the DMbQG framework may offer a partial resolution by reconciling a higher Hu2080 value with a consistent estimate of the Universe’s age.

This paper proposes a deterministic macroscopic model of thermal radiation from condensed matter, offering an alternative to stochastic noise approaches of fluctuational electrodynamics. Based on the concept of a continuous cascade buildup of intermittent self-oscillations of the electron subsystem during slow heating (the Bolero principle) and first-order linearized Maxwell equations, a rigorous analytical derivation of Wien’s spectral law is obtained. The thermal response parameter of a substance is expressed for the first time in terms of its fundamental macroscopic properties: the dynamic stiffness of the electron shell of the emitting center, the volumetric heat capacity of the lattice, and the unit cell volume. Numerical verification of the model using the high-temperature parameters of tungsten (W) is performed, demonstrating the exact convergence of the equations. An analytical relationship is established between the macroscopic rate of change of the medium’s temperature and the baseline amplitude of the radiation current.

The Gamma function diverges at negative integer and half-integer arguments, posing a fundamental obstacle for both perturbative and non-perturbative theories. Analytic continuation, while guaranteeing uniqueness, does not preserve the Euler integral representation in the left half-plane, as noted by Hardy and Titchmarsh. We present a continuous regularization technique - the Dual Architecture - that addresses this limitation through a complementary function F(z) with directional vector opposite to that of the Gamma function. The phase function C(z)=cosu2061(πz)-sinu2061(πz) is uniquely determined by the boundary conditions F(0)=1 and F(1/2)=-√π, and its periodicity is established by Lemma 2.1. The regularized function RΓ(z)=1/[C(z)Γ(1-z)] for R(z)≤0 is finite by construction at all points where the classical Gamma function diverges, unifying regulation and subtraction within a single definition. We demonstrate the physical applicability of the technique across six systems: the cosmological constant, the Higgs boson mass, the strong CP problem, the Casimir effect, dimensional regularization in d=3, and a divergent Gaussian integral. In each case, the algebraic development is presented in full, yielding analytical results consistent with experimental values. The technique offers a unified framework for treating Gamma-function divergences across perturbative and non-perturbative regimes.Keywords: Continuous regularization, Gamma function, uniqueness theorem, Casimir effect, Standard Model.

The field of real numbers is essential to many scientific disciplines. The first formal constructions—which appeared long after the field's initial discovery—involve properties crucial to its modern application, most notably the property of completeness. One of the most famous of these constructions implicitly relies on the Cantor-Dedekind axiom, a concept that has often sparked controversy within the mathematical community. This work aims to demonstrate the validity of the Riemann hypothesis within the axiomatic framework of ZF plus the Cantor-Dedekind axiom, utilizing a result concerning Euler's totient function derived from the study of cyclotomic polynomials.

The Cosmological Special Theory of Relativity (CSTR) relates a local, unexpanded spatial coordinate to the physically expanded coordinate of a Robertson-Walker universe through a cosmological expansion function τ (t0), and re-derives relativistic wave equations, electrodynamics, and general relativity within the resulting cosmological inertial frame (Yi, 2020, 2025). Companion reviews of this program have each found, for the specific quantities they consider — Yukawa interaction ranges and cross sections, Coulomb and hydrogen-like binding energies,Schwarzschild and Kerr-Newman horizon radii, parametrized post-Newtonian coefficients, and the fixed-epoch Lorentz transformation itself— that every physically measured quantity, once expressed in the physically expanded coordinate, recovers its ordinary, epoch-independentvalue, with the cosmological expansion function appearing only in the corresponding local-coordinate expression. This paper draws togetherthat recurring finding into an explicit observational assessment: because CSTR predicts no departure from ordinary physics for any process confined to a single cosmological epoch, the theory is not constrained, but also not yet tested, by existing single-epoch observations, including present bounds on the time-variation of the fine-structure constant and the proton-to-electron mass ratio from quasar absorption spectroscopy. We argue that a genuine test of CSTR requires a process that spans a cosmologically significant interval of time within a single observation — such as the redshift-drift (Sandage-Loeb) test, multi-epoch photon propagation, or cosmological particle creation — precisely the regime in which a companion review has shown that CSTR’s transformation law departs from a simple group structure. We summarize current observational bounds relevant to each sector of the theory and identify the redshift-drift test as the most concrete near-term observational program capable of constraining CSTR’s genuinely multi-epoch predictions.
