An Augmented Lagrangian Preconditioner for Navier–Stokes Equations With Runge–Kutta in Time

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 3, June 2026.
ABSTRACT We consider an implicit Runge–Kutta method for the numerical time integration of the nonstationary incompressible Navier–Stokes equations. This yields a sequence of nonlinear problems to be solved for the stages of the Runge–Kutta method. The resulting nonlinear system of differential equations is discretized using a finite element method.

On the Performance and Convergence of PINNs for Problems in Linear Elasticity

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Physics‐informed neural networks (PINNs) have emerged as a promising approach for solving partial differential equations by embedding physical laws directly into the loss function. However, their performance characteristics for problems in computational mechanics remain insufficiently understood.

On MAP Estimates and Source Conditions for Drift Identification in SDEs

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT We consider the inverse problem of identifying the drift in an stochastic differential equation (SDE) from n$n$ observations of its solution at M+1$M+1$ distinct time points. We derive a corresponding maximum a posteriori (MAP) estimate, we prove differentiability properties as well as a so‐called tangential cone condition for the forward ...

Emerging Treatments for Erectile Dysfunction

open access: yesTrends in Urology &Men's Health, Volume 17, Issue 3, June 2026.
ABSTRACT Erectile dysfunction (ED) is a prevalent condition that can significantly affect men's sexual health and quality of life, and for which there are many well‐studied effective treatments. In spite of this, many individuals still seek out alternative therapies.
