A unified gas-kinetic wave-particle method for multiscale binary-species gas mixtures

This paper presents a unified gas-kinetic wave-particle (UGKWP) method for simulating multiscale binary-species gas mixtures that accurately captures species-specific velocity and temperature differences across continuum to rarefied regimes by integrating a corrected equilibrium model, Shakhov-based Prandtl number correction, and improved particle transport mechanisms, while demonstrating strong agreement with DSMC results for hypersonic flows.

Limited Diffusion of Silicon in GaN: A DFT Study Supported by Experimental Evidence

This study combines first-principles DFT calculations with ultra-high-pressure annealing experiments to demonstrate that silicon diffusion in gallium nitride is extremely limited due to prohibitively high activation barriers, thereby confirming the material's stability for precise doping in advanced electronic applications.

Machine-Learned Force Fields for Lattice Dynamics at Coupled-Cluster Level Accuracy

This study demonstrates that machine-learned force fields trained on coupled-cluster data, enhanced by delta-learning and charge-aware approaches to address long-range effects and data limitations, achieve superior accuracy in predicting phonon dispersions and anharmonic vibrational properties for diamond and lithium hydride compared to traditional density functional theory.

Smart strategies to navigate turbulent odor plumes reorienting to local wind

This paper introduces a wind-relative reinforcement-learning framework for olfactory navigation in turbulent environments, demonstrating that an agent using only the time since the last odor detection and a locally estimated wind direction can outperform traditional strategies and adapt its behavior based on wind estimation quality in both mean wind and isotropic turbulence.
