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 ...

A Distribution Dynamics Approach to Regional GDP Convergence in Unified Germany [PDF]
This paper uses nonparametric techniques to study GDP convergence across German labor market regions and counties during the period 1992-2004. The main result is that regional convergence in unified Germany has been substantial.

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.

Convergence en loi de Dirichlet de certaines intégrales stochastiques [PDF]
Récemment, Bouleau a proposé une extension du principe d'invariance fonctionnelle de Donsker qui met en évidence la convergence en loi de Dirichlet d'une marche aléatoire erronée vers la structure d'Ornstein-Uhlenbeck sur l'espace de Wiener.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Advanced Functional Materials, EarlyView.Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Evaluating the Temporal and the Spatial Heterogeneity of the European Convergence Process, 1980-1999 [PDF]
In this paper, we suggest a general framework that allows testing simultaneously for temporal heterogeneity, spatial heterogeneity and spatial autocorrelation in b-convergence models.

Regional Disparities in the European Union: Convergence and Agglomeration [PDF]
Economic disparities between the regions of the European Union are of constant concern both for policy and economic research. In this paper we examine whether there are overlapping trends of regional development in the EU: overall convergence on the one ...

Advanced Functional Materials, EarlyView.A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

A STATISTICAL APPROACH OF THE SPATIAL-TEMPORAL VARIABILITY OF A PHENOMENON USING A RO-EU COMPOSITE INDEX [PDF]
This study aims at presenting a new computation index, which simultaneously measures the time and space variation of the various economic indices. The elaboration method of the space-time index is based on a matrix construct, the time and space variation
