Finite-Speed Thermal Relaxation in Strain-Gradient Thermoelastic Rods: Spectral Computation of Dispersion, Wavefronts, and Thermomechanical Coupling

This paper presents a reproducible spectral computation method for a one-dimensional strain-gradient thermoelastic rod with Cattaneo-type thermal relaxation, demonstrating how internal length scales induce short-wave dispersion and thermal relaxation times dampen temperature peaks while providing a high-precision benchmark for generalized thermoelasticity.

Theoretical upper bounds on gold production by mercury nuclear transmutation in a compact confinement apparatus

This paper establishes that while a theoretical material ceiling of nearly 700 kg of gold exists for mercury transmutation in a compact apparatus, practical constraints imposed by a 24-hour electrical budget and the lack of a fast-neutron source limit realistic yields to approximately 2 grams or less, rendering kilogram-scale production infeasible without unproven metric-enhancement factors.

Saturation-induced adaptive attractor in open non-equilibrium systems

This paper establishes a universal physical framework demonstrating that deep saturation in open non-equilibrium systems induces a derivative collapse onto stable, low-dimensional adaptive attractors, enabling autonomous state tracking and enhanced resilience across diverse fields without the need for active feedback.

Thermodynamic cost of inference and learning in physical neural networks

This paper demonstrates that while quasi-static inference in physical neural networks incurs no thermodynamic cost, learning parameters carries an irreducible energy expense, establishing that the fundamental thermodynamic price of neural computation is determined by memory storage rather than arithmetic processing.

Cauchy problem for the localized wave propagation in continuous model of the one-dimensional diatomic crystal

This paper constructs asymptotic solutions for the Cauchy problem of localized wave propagation in a continuous one-dimensional diatomic crystal model, deriving analytical formulas via Airy functions that depend on the ratio between the lattice step and the initial perturbation size.

Quantization-locked attractors and deterministic stabilization of localized wave packets in discrete nonlinear systems

This paper introduces the concept of quantization-locked equilibria, demonstrating how resonant alignment between discrete control lattices and nonlinear invariants in digitized systems can fracture continuous existence curves into stable fixed points, thereby suppressing drift and enabling the deterministic stabilization of localized wave packets over extended propagation distances.

Nonlinear oscillatory flow regimes with mixing in a two-layer fluid under a rigid lid

This paper presents a nonlinear long-wave model for internal waves and turbulent mixing in a two-layer fluid under a rigid lid, which incorporates non-hydrostatic effects and vorticity to construct stationary oscillatory solutions and develop an efficient numerical algorithm for simulating their unsteady evolution driven by fluid inflow.

DFT insights into structural, electronic and optical characteristics of undoped and Sc-doped GeO2 rutile

This study employs density functional theory to demonstrate that scandium doping stabilizes the rutile phase of GeO₂, reduces its bandgap to induce p-type conductivity, and enhances its optical properties, making it a promising candidate for advanced optoelectronic devices and UV detection.
