Room‐temperature dislocation plasticity in ceramics: Methods, materials, and mechanisms

Journal of the American Ceramic Society, Volume 108, Issue 9, September 2025.
Abstract Dislocation‐mediated plastic deformation in ceramic materials has sparked renewed research interest due to the technological potential of dislocations. Despite the long research history of dislocations as one‐dimensional lattice defects in crystalline solids, the understanding of plastically deformable ceramics at room temperature seems ...

Hybrid Modeling of the Reversed‐Phase Chromatographic Purification of an Oligonucleotide: Few‐Shot Learning From Differentiable Physics Solver‐in‐the‐Loop

Biotechnology and Bioengineering, Volume 122, Issue 8, Page 2179-2192, August 2025.
The DP‐SOL hybrid modeling framework was employed to model the reversed‐phase chromatographic purification of oligonucleotides. By combining differentiable physics and neural networks at the solver level, DP‐SOL outperforms traditional mechanistic models in prediction accuracy, captures complex process dynamics and offers a robust approach for ...

Application of the Finite Element Method to Rotary Wing Aeroelasticity [PDF]

A finite element method for the spatial discretization of the dynamic equations of equilibrium governing rotary-wing aeroelastic problems is presented. Formulation of the finite element equations is based on weighted Galerkin residuals.

Non‐Hydrostatic Model for Simulating Moving Bottom‐Generated Waves: A Shallow Water Extension With Quadratic Vertical Pressure Profile

International Journal for Numerical Methods in Fluids, Volume 97, Issue 8, Page 1093-1103, August 2025.
In this article, we derive a non‐hydrostatic extension to the SWE to solve bottom‐generated waves along with its pressure relation. This relation is built on a linear vertical velocity assumption, leading us to a quadratic pressure profile, where we alternatively write it so that we can solve it by a projection method without ambiguity due to the ...

Spatially Periodic Solutions for Evolution Anisotropic Variable‐Coefficient Navier–Stokes Equations: II. Serrin‐Type Solutions

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 11592-11619, August 2025.
ABSTRACT We consider evolution (nonstationary) space‐periodic solutions to the n$$ n $$‐dimensional nonlinear Navier–Stokes equations of anisotropic fluids with the viscosity coefficient tensor variable in space and time and satisfying the relaxed ellipticity condition.

A Stable Hybridized Discontinuous Galerkin Method for Solving Some Nonlinear m‐Component Reaction–Diffusion Systems

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12405-12420, August 2025.
ABSTRACT In this paper, we present a stable numerical scheme for solving two‐dimensional m$$ m $$‐component reaction–diffusion systems. The proposed approach utilizes the backward Euler method for temporal discretization and the hybridized discontinuous Galerkin (HDG) method for spatial discretization.

Difference interior penalty discontinuous Galerkin method for the 3D elliptic equation

Results in Applied Mathematics
This paper presents a difference interior penalty discontinuous Galerkin method for the 3D elliptic boundary-value problem. The main idea of this method is to combine the finite difference discretization in the z-direction with the interior penalty ...

Onshore Entrapment of Seawater in Coastal Aquifers by Rapid Coastline Progradation

Water Resources Research, Volume 61, Issue 8, August 2025.
Abstract We hypothesize that brackish groundwater within unconfined aquifers located in active river deltas may have resulted from rapid shoreline progradation during the Holocene. To explore this hypothesis, we develop a coupled model of variable‐density groundwater flow and solute transport within a prograding sedimentary delta.
