A Phasefield Model for Combined Brittle and Ductile Fracture in a Heterogeneous Domain
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT This contribution presents a phasefield approach to simulating combined brittle and ductile fracture in a materially heterogeneous domain consisting of a ductile 100Cr6 steel matrix and various non‐metallic, brittle inclusions. The matrix subdomain is modeled with von Mises plasticity with linear isotropic hardening, while the inclusions are ...

A Mixed Discrete Cosserat Rod Formulation
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT In this communication we propose a discrete Cosserat rod formulation in which a slender elastic rod is represented as a chain of rigid bodies (nodes) coupled by compliant elastic forces and moments acting between adjacent node pairs. Discrete dilatation, shear, torsion and curvature strain measures are evaluated from the relative kinematics of

Sodium Ions Affect GPR17 Conformational States and Functionality
Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 12, Page 1949-1964, December 2026.ABSTRACT Sodium is an allosteric modulator of several class‐A GPCR regulating active versus inactive conformation state and may be a critical issue for the optimization of crystallization procedures. Herein, the role of Na+ in the regulation of GPR17 conformational states was studied through MD simulations of GPR17 wild‐type and mutated on two ...

Nonparametric Conditional Copula Density Estimation With Applications to the Body Mass Index
Stat, Volume 15, Issue 4, December 2026.ABSTRACT This study develops a nonparametric conditional copula density estimator that features a parametric carrier copula refined by an exponential series adjustment. We adopt the local likelihood approach for conditional distribution estimation and incorporate the influence of covariates via kernel smoothing.

A Geometric Multigrid Preconditioner for Discontinuous Galerkin Shifted Boundary Method
International Journal for Numerical Methods in Engineering, Volume 127, Issue 21, 15 November 2026.ABSTRACT I introduce a geometric multigrid preconditioner for the Shifted Boundary Method (SBM) designed to solve PDEs on complex geometries. While the SBM simplifies mesh generation by using a nonconforming background grid, it often results in nonsymmetric linear systems, a complete analysis of which is missing from the literature, especially with ...

Accelerated Newton-Raphson power flow
, 2011 This paper introduces the Newton-like method of modifying the right-hand-side vector into the power flow solution. Based on this method, the accelerated Newton–Raphson (ANR) power flow algorithm is proposed. In the proposed algorithm, a constant Jacobian
