On Compressible Fluid Flows of Forchheimer‐Type in Rotating Heterogeneous Porous Media

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 15010-15055, 15 September 2026.
ABSTRACT We study the dynamics of compressible fluids in rotating heterogeneous porous media. The fluid flow is of Forchheimer‐type and is subject to a mixed mass and volumetric flux boundary condition. The governing equations are reduced to a nonlinear partial differential equation for the pseudo‐pressure.

Maximum‐Entropy‐Based Meshless Modeling of Surface‐Tension‐Driven Large Deformation

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT Soft material modeling is challenging due, among others, to the substantial structural changes these materials undergo. In this context, meshless methods offer a promising alternative to overcome the limitations of established mesh‐based approximations such as finite elements. However, they introduce new challenges.

Hybrid Coupling With Operator Inference and the Overlapping Schwarz Alternating Method

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT This paper presents a hybrid approach for coupling subdomain‐local, nonintrusive Operator Inference (OpInf) reduced order models (ROMs) with each other and with subdomain‐local, high‐fidelity full order models (FOMs) using the overlapping Schwarz alternating method (O‐SAM).

Multiobjective integer and mixed-integer nonlinear programming: exact approaches and applications.

open access: yes
Multiobjective optimization comes into play in many real world problems, e.g. finance, production planning, biology, medical imaging, transportation. Some of these applications require to include integer variables in the optimization model, in order to give a proper description of the problem. Thus, multiobjective integer and mixed integer optimization

Toward Coherent Polaritonic Devices Operating at Room Temperature

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
Polariton condensate formation and long‐range coherent transport is demonstrated using molecular exciton polaritons at room temperature (left). Waveguides and related photonic structures, such as Y‐splitters and interferometers, are realized via a focused ion beam etching of the planar microcavity. Coherent propagation of the condensate is demonstrated
