Predicting spacecraft surface degradation under atomic oxygen in Low Earth Orbit

This paper presents a first-principles multiscale framework that successfully predicts both the erosion yields and evolving surface microstructures of spacecraft materials exposed to atomic oxygen in Low Earth Orbit by linking atomic-scale reactive molecular dynamics simulations with a macro-scale statistical surface model.

Integration of a Structural Coherence Model with a Semi-Universal Machine Learning Interatomic Potential to Predict Molten Salt Thermal Conductivity

This paper presents an integrated methodology combining SuperSalt machine-learning interatomic potentials with a structural coherence model to rapidly predict the thermal conductivity of molten salts with experimental-level accuracy at a fraction of the computational cost of traditional molecular dynamics simulations.

Demonstration of Continuous Net-Energy Production in Tomoiu Internal Confinement Fusion (TICF) Reactors

This paper reports the development and experimental validation of the Tomoiu Internal Confinement Fusion (TICF) process, a hybrid chemical-thermonuclear system that allegedly achieved continuous net-positive energy production (Q-values of 2–8) through aneutronic fusion reactions without measurable neutron or gamma radiation. A TICF demonstration reactor has been assembled at the Tomoiu Advanced Fusion Energy (TAFE) laboratory and is available for direct observation of continuous net-positive thermal energy production. The reported performance exceeds an 800% thermal energy gain under the demonstrated operating conditions, providing an opportunity for researchers, engineers, investors, and energy stakeholders to independently evaluate this emerging technology.

Spacetime Emergence from Flux-Tube Connectivity: A Flux-First Framework, Renormalization-Group Analysis, String-Theoretic Embedding, and First Numerical Tests

This paper proposes a "flux-first" framework where classical spacetime, gravity, and black hole thermodynamics emerge from the coarse-grained connectivity of a quantized flux-tube network, demonstrating through renormalization-group analysis, string-theoretic embedding, and numerical Monte Carlo tests that this approach naturally yields an induced Einstein–Hilbert action, the Bekenstein–Hawking area law, and a resolution of the gravity–QCD hierarchy.

The Indispensable Present: reactive reading, dissipative writing, and the structural coherence of the dark sectors

This paper proposes a formal framework for "Time Cosmology" that distinguishes itself from standard interacting dark energy models by positing that the present (visible/acoustic sector) is physically indispensable as a dissipative mediator for irreversible "writing" of the dark matter record, while the dark sectors engage only in non-dissipative "reading," thereby establishing a unique structural coherence and a measurable arrow of time without invoking new fifth forces.

High-Entropy Oxide (HEO) and Multi-Metallic Core-hell Nanocomposite for Multi- shielding Application (Gamma and Thermal Neutron)

This study demonstrates that high-entropy oxide polymer nanocomposites and borate glass systems featuring specialized core-shell architectures offer a lightweight, non-toxic, and highly efficient solution for simultaneous gamma-ray and thermal neutron shielding, achieving superior attenuation performance with less than 1% deviation from Geant4 simulations.
