Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids
Advanced Functional Materials, EarlyView.This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Structural Breaks and Convergence in Output Growth in the EU [PDF]
Convergence is defined for a multivariate time-series model of output with breaks in intercepts and in time trends. Using OECD quarterly data on output from 1980, the convergence hypothesis is tested across seven European economies, Belgium, Finland ...

core
Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Maximal uniform convergence rates in parametric estimation problems [PDF]
This paper considers parametric estimation problems with i.i.d. data. It focusses on rate-effciency, in the sense of maximal possible convergence rates of stochastically bounded estimators, as an optimality criterion, largely unexplored in parametric ...

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry
Advanced Functional Materials, EarlyView.In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

A new Concept of Convergence Space
, 2008 The notion of b-convergence is presented for studying preuniform convergence spaces in the sense of Preuß (1993) and set-convergence spaces introduced by Wyler in 1989 from a common point of view. The well-known supertopologies as defined by Doitchinov in 1964 and also the filtermerotopies in the sense of Kat´etov (1965) can be integrated as well. Even

Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells
Advanced Functional Materials, EarlyView.Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

On SI2-convergence in T0-spaces
Open MathematicsRecently, Shen et al. showed that the SI2-topology on a T0{T}_{0}-space can be described completely in terms of SI2-convergence, and the SI2-convergence is topological whenever the given space is SI2-continuous.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides
Advanced Functional Materials, EarlyView.We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and
