Polynomial‐shaped electrodes for adaptive X‐ray optics

Journal of Synchrotron Radiation, EarlyView.
A shaped electrode design for lithium niobate adaptive X‐ray mirrors connects actuator degrees of freedom to specific polynomial orders, enabling general shape control and the correction of defocus, coma and fourth‐order aberrations with a limited number of inputs.For adaptive mirrors on X‐ray beamlines and optical systems, we describe a strategy for ...

From analytical to data‐driven: multi‐method optimization of a bendable mirror system for dynamic focusing

Journal of Synchrotron Radiation, EarlyView.
A small‐radius‐of‐curvature bendable mirror system is developed for dynamic focusing in X‐ray free‐electron laser and synchrotron radiation beamlines, and a transfer‐learning neural‐network and differential‐evolution framework is used for force‐to‐shape modeling and inverse optimization.

Embedding wellformed Euler diagrams [PDF]

, 2008
Euler diagrams are collections of labelled closed curves. They are often used to represent information about the relationship between sets and, as such, they have numerous applications including: visualizing biological data, diagrammatic logics, and ...

Multiscale Modelling of Frame Structures With Lattice‐Like Mesostructures Using Finite Beam Elements at the Macro and Meso Level

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT In this contribution, we present a FE2${\rm FE}^2$ model for shear‐flexible beams with a lattice‐like meso structure. The meso structure consists of a network of beams. The meso ‐ and macroscale are coupled by means of the Hill–Mandel condition.

Global Graph Surrogates and Neural Graph Elements for Computational Mechanics

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Machine learning surrogates are increasingly used to accelerate physics‐based simulations by predicting full‐field responses at a fraction of the computational cost. In this contribution, we present two complementary graph‐based approaches for surrogate modelling in computational mechanics.

Drawing Euler Diagrams with Circles and Ellipses [PDF]

, 2011
The use of Euler diagrams as a basis for visual languages is commonplace and they are often used for visualizing information. The ability to automatically draw these diagrams is, therefore, likely to be of widespread practical use.

A Spike‐Based Graph Surrogate for Modeling Finite Element Structures

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The use of Artificial Intelligence (AI) in structural mechanics has grown substantially in the recent years, with diverse applications ranging from constitutive laws and Gauss‐point‐level enhancements to the complete replacement of classical Finite Element Methods (FEM) with surrogate models.

Capability and Limitations of a Tuned Mass Damper for a 15‐MW Semisubmersible Floating Wind Turbine

Wind Energy, Volume 29, Issue 11, November 2026.
ABSTRACT Large floating offshore wind turbines (FOWTs) under coupled aerodynamic and hydrodynamic loading exhibit broadband low‐frequency response in addition to the platform‐pitch resonance. Tuned mass dampers (TMDs) have been studied for a range of applications, but their net benefit under fully coupled operational conditions has not been quantified.

Elastomeric 3D‐Printed Microenvironments Enable Nanonewton Force Measurements in Healthy and Diseased Human Pluripotent Stem Cell‐Derived Neuroepithelial Cells

Advanced Materials, Volume 38, Issue 56, 8 October 2026.
We present elastomeric three‐dimensional (3D) microstructures fabricated via two‐photon polymerization (2PP) and post‐processed through wet etching, for quantifying nanonewton (nN)‐scale forces applied by healthy and diseased neural cells. The mechanically characterized free‐standing beam architectures enable measurement of traction forces of ...
