Schrödinger–Navier–Stokes–π Unified Computational Framework : A Unified Theoretical and Numerical Architecture for Quantum-Coherent Fluid Dynamics Across Physical and Biological Scales
(Publisher, 2025-12-05) Barack Ndenga
The coexistence of quantum coherence, nonlinear fluid dynamics, and biomolecular π-fields within biological and nanoscale systems requires a unified mathematical description. Classical hydrodynamics alone fails to capture coherence propagation, while the linear Schrödinger equation cannot model dissipation, viscosity, or turbulence. Here, I introduce the Schrödinger–Navier–Stokes–π Unified Computational Framework, a novel equation set combining: the quantum phase field of the Schrödinger equation, the viscous and nonlinear transport of Navier–Stokes dynamics, the curvature-driven quantum π-potential, and a hybrid Hamiltonian–dissipative evolution capturing both coherence and irreversible flow. This framework predicts quantum-fluid transitions, π-induced tunneling acceleration, coherence-enhanced mixing, nanoscale turbulence, and dynamic switching between classical and quantum transport regimes. It provides a general model applicable to biology, nanotechnology, photonics, and quantum materials.

Quantum-Fluid Interpretation of Enzymatic Tunnels and Energy Transport
(Publisher, 2025-12-04) Barack Ndenga
Enzymatic tunnels—internal channels guiding substrates, protons, electrons, or conformational energy—are traditionally described using classical diffusion, transition state theory, or vibrational coupling. Here, I propose a novel framework: the Quantum-Fluid Interpretation, where enzymatic tunnels behave as coherent nano-fluids governed by π-field dynamics, enabling long-range energy transport, ultrafast communication, and directionality without significant energy loss. This model integrates quantum hydrodynamics, π-coherence fields, and nonlinear curvature-driven flows to describe tunneling, proton transfers, allosteric propagation, and catalytic acceleration. To my knowledge, this is the first article to formalize enzymatic tunnels as quantum fluid conduits, establishing a new branch of bio-quantum dynamics.

2D Fracture Network Mathematics
(SCIRP, 2025-12-03) Daniel Brox
2D elastostatic displacement solutions for the Yoffe Mode I and Rice Mode II crack models are reviewed. These solutions are used to introduce the elastostatic displacement solution for a 2D Mode I/II multi-crack configuration in terms of meromorphic differential forms on a hyperelliptic curve. Using the multi-crack solution, a picture of crack growth as motion of a point in a moduli space of Riemann surfaces is presented, whereby the the final rupture configuration of the crack may be associated with a singular Riemann surface such as a Riemann sphere with a pair of points identified.

Nano-Turbulence in Biological Systems: A New Paradigm
(Publisher, 2025-12-03) Barack Ndenga
Turbulence has traditionally been considered impossible in nanoscale biological environments due to strong viscous damping and low Reynolds numbers. Here I introduce the concept of nano-turbulence: a novel, coherence-driven, hydrodynamic-like regime emerging from quantum π-field dynamics within biomolecules, particularly proteins. Building on the bio-quantum framework of Quantum π in Biomolecular Dynamics, I show that proteins behave as nano-quantum fluids, supporting internal vortices, coherence eddies, and structured π-flow cascades. This article develops the mathematical foundations of nano-turbulence, characterizes its structural origins (aromatic networks, hydrogen bonds, curvature funnels), and discusses its functional consequences for allostery, mutation sensitivity, catalytic efficiency, and quantum energy transport. To the best of my knowledge, this is the first formal scientific proposal of nano-turbulence as a biological phenomenon, establishing a new paradigm in quantum biophysics.

What are the basic substances of the universe? Current research and future predictions
(2025) Y Liu
Exploring the fundamental components of the universe remains one of the most profound challenges in science. Although significant progress has been made in terms of particles and forces, the composition of the universe is far from being solved. This article explores the hypothesis that the most basic matter in the universe is composed of four interrelated elements: matter, energy, time and space. We believe that these components are not only the basis of physical phenomena, but also the basic components of atoms and the universe. This article describes the advantages and limitations of established theories such as Standard Model and General Relativity, and draws evidence from cosmology, quantum mechanics, and particle physics, and conducts in-depth research on the complex relationships of matter, energy, time and space on different scales. By proposing the overall framework for the interaction of these four elements, we raise the need for future physics research to unify the microscopic and macroscopic worlds and explore other long-standing major issues in physics.
