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.

Advanced Functional Materials, EarlyView.Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Advanced Functional Materials, EarlyView.Photoaligned and photopatterned liquid crystal platforms provide programmable control of optical phase, polarization, and spin‐orbit interactions, enabling compact generation of structured light and complex wavefronts. This review highlights how tailored molecular orientations transform simple beams into designed optical fields, opening versatile ...

Web matrices : structural properties and generating combinatorial identities [PDF]
, 2016 In this paper we present new results for the combinatorics of web diagrams and web worlds. These are discrete objects that arise in the physics of calculating scattering amplitudes in non-abelian gauge theories.

Advanced Functional Materials, EarlyView.Electroforming‐free TiN/SiOx/Cu/SiOx/TiN memristive devices exploit pancake‐like Cu nanoparticles embedded in a SiOx double layer to create a heterogeneous Schottky‐barrier landscape. Under bias, oxygen‐vacancy redistribution progressively lowers local barriers and recruits initially inactive Cu‐PC pathways into a parallel conduction ensemble, enabling

Factoring Pattern-Free Permutations into Separable ones [PDF]
International audienceWe show that for any permutation π there exists an integer k π such that every permutation avoiding π as a pattern is a product of at most k π separable permutations. In other words, every strict class C of permutations is contained

Positroid Links and Braid varieties [PDF]
, 2022 57 PagesWe study braid varieties and their relation to open positroid varieties. First, we construct a DG-algebra associated to certain braid words, possibly admitting negative crossings, show that its zeroth cohomology is an invariant under braid ...

Chemically Fueled Systems Chemistry Across Length Scales
Advanced Functional Materials, EarlyView.Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

A decomposition of Solomon's descent algebra [PDF]
, 1989 A descent class, in the symmetric group Sn, is the collection of permutations with a given descent set. It was shown by L. Solomon (J. Algebra41 (1976), 255–264) that the product (in the group algebra Q(Sn)) of two descent classes is a linear combination

Advanced Healthcare Materials, EarlyView.A biocompatible sodium alginate‐based hydrogel is developed as a next‐generation submucosal lifting agent intended for EMR and ESD. The optimized formulation exhibits a composition devoid of endotoxins, high viscosity, demonstrates reliable injectability, and ensures prolonged mucosal elevation.
