A Corrected Open Boundary Framework for Lattice Boltzmann Immiscible Pseudopotential Models

This paper proposes a corrected open boundary framework based on the Multiple-relaxation-time (MRT) lattice Boltzmann method for immiscible pseudopotential models, which significantly reduces spurious currents and ensures global mass conservation through improved inlet reconstruction, dynamic outlet velocity adjustment, and viscosity-based stability tuning, as validated by four benchmark simulations showing high accuracy in droplet morphology and flow behavior.

Ceci n'est pas un committor, yet it samples like one: efficient sampling via approximated committor functions

This paper proposes a computationally efficient enhanced sampling method that approximates the machine-learned committor function entirely within descriptor space to bypass costly coordinate gradients, thereby retaining robust sampling performance while enabling the study of rare events previously infeasible with the original formulation.

Hyper-reduction methods for accelerating nonlinear finite element simulations: open source implementation and reproducible benchmarks

This paper presents an open-source implementation and reproducible benchmarks using libROM, Laghos, and MFEM to evaluate the trade-offs between accuracy and computational efficiency of various hyper-reduction methods, such as gappy POD interpolation and the empirical quadrature procedure, across nonlinear diffusion, elasticity, and Lagrangian hydrodynamics problems, ultimately demonstrating that optimal method selection depends on the specific physics and time integration scheme employed.
