Acoustic radiation of thermodiffusively unstable turbulent lean premixed hydrogen-air flames

This study utilizes Direct Numerical Simulations to demonstrate that thermodiffusive instabilities in turbulent lean premixed hydrogen-air flames significantly enhance low-frequency combustion noise by altering heat release fluctuations and flame surface dynamics through the coupled action of turbulence and flame stretch, distinguishing their acoustic behavior from stable methane flames.

A quantitative analysis of semantic information in deep representations of text and images

This paper employs Information Imbalance to demonstrate that semantic information converges across languages, modalities, and architectures in deep models, revealing that predictability is strongest in specific central or final layers and that larger, independently trained models can outperform jointly trained multimodal models in cross-modal alignment.

Analysis of molecular dynamics simulation data via statistical distances between covariance matrices

This paper proposes a data-efficient statistical framework that quantifies discrepancies in molecular dynamics simulations by measuring distances between covariance matrices, enabling the extraction of low-dimensional features that effectively correlate with global physical properties like diffusion coefficients and distinguish between different phases such as ice and liquid water.
