Diffusion-corrected Autoregressive Fourier Neural Operator for Droplet Evolution Prediction

This paper introduces DiffARFNO, a two-stage framework combining an autoregressive Fourier-MIONet for coarse long-horizon forecasting with a conditional DDIM corrector for fine-detail refinement, which significantly improves the accuracy of droplet evolution predictions in inkjet printing compared to existing state-of-the-art models.

Dynamics of phase space vortices in Vlasov plasmas with ion scale inhomogeneity : I Constant frequency drive study

This paper utilizes high-resolution Vlasov-Poisson simulations to investigate the formation dynamics, stability, and mode coupling of phase space vortices in a collisionless plasma, revealing how a quasi-stationary ion scale inhomogeneity influences electron acoustic wave evolution and triggers ion trapped particle instability.

Lattice initialisation and finite-size effects of non-equilibrium molecular dynamics simulations for heat transfer across graphene-copper interfaces

This study demonstrates that Kapitza resistance at graphene-copper interfaces in non-equilibrium molecular dynamics simulations is highly sensitive to lattice initialization and residual strain, which can cause a two-fold variation in thermal resistance through strain-dependent phonon spectral shifts and the formation of damping boundary layers, rather than being primarily determined by domain size or simple phonon spectral overlap.

Dynamics of phase space vortices in Vlasov plasmas with ion scale inhomogeneity : II Chirped frequency drive study

This study utilizes a Vlasov-Poisson solver to investigate how background quasi-stationary ion scale inhomogeneity, previously established in Part I, influences the formation and dynamics of phase space vortices under chirped frequency drives, revealing distinct behaviors such as early Langmuir mode onset, suppressed vortex sizes, and altered particle trapping fractions compared to homogeneous plasma cases.

Response-function-optimized phase field modeling of solute trapping and solute drag in rapid alloy solidification

This paper introduces an optimization-based calibration strategy for phase field modeling that embeds target sharp-interface response functions into dilute alloy simulations by treating interfacial diffusivity as a tunable parameter, thereby enabling accurate quantitative prediction of solute trapping, solute drag effects, and resulting microstructural transitions in rapidly solidified multicomponent alloys.

Grounded verification of chemical and materials reasoning: detection is the bottleneck

This paper demonstrates that for large language models reasoning about chemistry and materials, a tiered, database-grounded verification system that prioritizes detecting specific factual errors over blanket retrieval significantly reduces confabulation rates by enabling targeted repairs, thereby identifying error detection rather than correction as the primary bottleneck in improving model accuracy.

Modeling rare-earth and energy materials supply chains under theoretical China-outer-Mongolia political reunification scenarios

This paper employs a dynamic partial equilibrium Stackelberg model to simulate the 2026–2036 supply chains of critical minerals under three scenarios, including a theoretical political reunification of China and Outer Mongolia, to evaluate how deep resource integration and infrastructure development impact global supply security and China's social welfare.
