Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

The Employment of Mothers: Recent Developments and their Determinants in East and West Germany [PDF]
We apply German Mikrozensus data for the period 1996 to 2004 to investigate the employment status of mothers. Specifically, we ask whether there are behavioral differences between mothers in East and West Germany, whether these differences disappear over

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Near‐Field Electrospinning Micro‐Printhead Achieves Precise Control of Nanofiber Deposition
Advanced Engineering Materials, EarlyView.A micro‐printhead for near‐field electrospinning enables reproducible deposition of polymer nanofibers with diameters below 50 nm. Systematic parameter studies uncover the mechanisms linking operating conditions to fiber morphology, paving the way for precise and low‐cost nanoscale 3D manufacturing.As a high‐resolution, cost‐effective, and rapid ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Wage Convergence and Inequality after Unification: (East) Germany in Transition [PDF]
This paper investigates the wage convergence between East German workers and their West German counterparts after reunification. Our research is based on a comparison of three groups of workers defined as stayers, migrants and commuters to West Germany ...

East Germany overtakes West Germany: recent trends in order-specific fertility dynamics [PDF]
Some 20 years after unification, the contrast between East and West Germany provides a unique natural experiment for studying the persistence of communist-era family patterns, the effects of economic change, and the complexities of the process of ...

Raumforschung und Raumordnung, 2009 This article analyses internal labour mobility within Germany, distinguishing between migration and commuting and between different educational levels. Our results show that mobility flows in Germany are influenced mostly by differences in labour market
