Acceleration Technique for the Augmented IIM for 3D Elliptic Interface Problems
NUMERICAL MATHEMATICS-THEORY METHODS AND APPLICATIONS, 14(3), 773–796.
author keywords: 3D elliptic interface problem; augmented IIM; fast Poisson solver; directional least squares interpolation

Integration of neural networks with numerical solution of PDEs for closure models development
PHYSICS LETTERS A, 406.
Contributors: A. Iskhakov n , N. Dinh n & E. Chen n
author keywords: Physics-informed machine learning; PDE-integrated neural network; Closure model
TL;DR:
Despite its complexity and computational cost, the proposed physics-integrated ML shows a potential to develop a "PDE-Integrated" closure relations for turbulent models and offers principal advantages, namely: the target outputs for a DFNN might be unknown and can be recovered using the knowledge base (PDEs).

Geometric singular perturbation theory analysis of an epidemic model with spontaneous human behavioral change
JOURNAL OF MATHEMATICAL BIOLOGY, 82(6).
author keywords: Epidemiological modeling; Entry-exit function; Geometric singular perturbation theory; Imitation dynamics; Evolutionary game theory
MeSH headings : Behavior; Biological Evolution; Epidemics; Game Theory; Humans; Models, Biological
TL;DR:
It is shown that the entry–exit function of geometric singular perturbation theory can be used to analyze the Poletti model in the limit in which behavior changes on a much faster time scale than that of the epidemic.

Uncertainty Quantification and Sensitivity Analysis of Partial Charges on Macroscopic Solvent Properties in Molecular Dynamics Simulations with a Machine Learning Model
JOURNAL OF CHEMICAL INFORMATION AND MODELING, 61(4), 1745–1761.
MeSH headings : Machine Learning; Molecular Dynamics Simulation; Solvents; Static Electricity; Uncertainty
TL;DR:
The results indicate that the effect of partial charge variance on bulk properties, such as solubility parameters, diffusivity, dipole moment, and density, measured from MD simulations is significant; however, measured properties are observed to be less sensitive to partial charges of less accessible atoms.
