Advanced Functional Materials, EarlyView.Schematic illustration of ferroelectric‐intercalation‐driven transitions in magnetic configurations and magnonic topological phases, together with the symmetry relations of magnonic Berry curvature. ABSTRACT Magnons in collinear magnets with vanishing net magnetization offer unique advantages for spin transport, including ultrafast dynamics and ...

Geophysical Research LettersThe doldrums are regions of low wind speeds and variable wind directions in the deep tropics that have been known for centuries. Although the doldrums are often associated with the Intertropical Convergence Zone (ITCZ), the exact relationship remains ...

Spatial and non spatial approaches to agricultural convergence in Europe
The paper starts from the critiques to the Barro-style methodology for convergence analysis with the aim of reviewing the econometric approaches for testing spatial effects in convergence process related to both cross sectional and panel data regressions,

Is dualism still a source of convergence in Europe? [PDF]
This paper aims at assessing whether dualistic mechanisms represent a significant component of the aggregate labour productivity convergence observed across the European regions in the 1980s. The potential of an explanation of convergence based - in part,

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Regional Convergence in Germany. A Geographically Weighted Regression Approach [PDF]
Regional convergence of German labour markets represents a politically important question. Different studies have examined convergence processes in Germany. We derive equations to estimate the speed of convergence on the basis of an extended Solow model.

Spatial dependence and regional convergence in Brazil
Investigaciones Regionales - Journal of Regional Research, 2005 The present paper introduces some spatial econometric techniques to the convergence issue among Brazilian states. State data over the 1970-95 period are considered to explore previous results that suggested convergence. As in the US case, strong patterns of spatial correlation are found during the period.

Convergence research for sustainable regional systems
iScienceConvergence research addresses societal and environmental challenges by co-creating knowledge across disciplinary boundaries, often in deep collaboration with extra-academic parties to ensure that the research process is solution-focused, actionable, and just. As part of National Science Foundation (NSF)-funded research projects on sustainable regional

Advanced Functional Materials, EarlyView.A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Is East Germany Catching Up? A Time Series Perspective [PDF]
This paper assesses whether the economy of East Germany is catching up with the West German region in terms of welfare. While the primary measure for convergence and catching up is per capita output, we also look at other macroeconomic indicators such as
