Recalculating the Mass of Earth The Bipartite Nature of Mass and the Recovery of Atomic Mass from Dodecahedral Quanta

This paper proposes a bipartite ontology of mass within an Info-Magneto-Electrostatic framework, arguing that the Earth's catalogued mass conceals distinct inert (Mahatva) and interactive (Gurutva) components derived from a viscous celestial plenum and dodecahedral quanta, thereby reinterpreting gravity as a plenum vortex pressure gradient rather than an intrinsic property of matter.

A solution method for Doppler effects in a uniform flow

This paper presents a general integral solution for acoustic waves in a uniform flow to analyze Doppler effects from moving time-harmonic sources, specifically examining linear and circular motions while offering a unified numerical procedure for calculating frequency shifts.

Solitary waves for a higher-order Boussinesq system: Stability and numerical experiments

This paper establishes the orbital stability of solitary-wave solutions for a class of higher-order Boussinesq systems using variational methods and asymptotic connections to fifth-order KdV equations, while numerical experiments suggest that the stability range for wave velocities may be broader than theoretical predictions.

Predicting Proximity-Controlled Magnetism in Two-Dimensional van der Waals Heterostructures from First Principles

This paper establishes a first-principles workflow to predict proximity-controlled magnetism in 2D van der Waals heterostructures, demonstrating that a WTe2 substrate reorients CrI3 magnetization from out-of-plane to in-plane by inducing substrate-driven changes in symmetric anisotropic exchange.

Graphite Thermodynamic Properties: Hybrid Debye Model

This paper presents a hybrid 1D/2D Debye model incorporating a Fermi electron gas that accurately reproduces the thermodynamic properties of graphite and related carbon species from 300 K to 6000 K, demonstrating that accounting for anisotropic lattice vibrations is more critical than including anharmonicity.

On the possibility of using corundum to create sensitive VUV, UV and IR detectors

This study demonstrates that corundum crystals, when modified with specific activators and ion irradiation, can function as sensitive photoconverters and detectors across the VUV, UV, and IR spectral ranges.

From Geometric Perfection to Flight Stability: The Development and Empirical Validation of a 36-Hole Pickleball Based on Archimedean Solid Principles

This study empirically validates that a novel 36-hole pickleball, designed based on Archimedean solid principles, exhibits significantly superior flight stability and more compact landing dispersion compared to a standard 40-hole ball.

Gravity from Relative Entropy: Jackiw–Teitelboim Dynamics on the Nariai Horizon

By shifting the derivation of gravity from relative entropy from local Rindler horizons to the compact Nariai horizon, this paper demonstrates that the relative entropy of coherent s-wave excitations reproduces the Einstein coupling without infinite-area subtractions and reveals that the resulting backreaction is exactly linearized Jackiw–Teitelboim gravity.

Longitudinal dispersion in fluvial environments: new empirical formulations and applications to pollutant transport modeling

This paper proposes new empirical formulations for the longitudinal dispersion coefficient in narrow and wide fluvial channels based on channel aspect ratio and shear velocity, validates them against existing models and field data, and demonstrates their effectiveness in numerically simulating pollutant transport dynamics for both instantaneous and continuous release scenarios.

Multi-dimensional spatiotemporal patterns and transverse wave interactions of ideal detonations in small size rectangular channels

This study investigates how channel size and multi-dimensional transverse wave interactions, particularly the formation of rotating oblique triple lines and Mach transverse waves, govern the complex helical propagation patterns, overpressure dynamics, and hydrodynamic instability of ideal detonations in small rectangular channels.
