Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

Advanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

Practical identification of NARMAX models using radial basis functions [PDF]

, 1990
A wide class of discrete time non-linear systems can be represented by the non-linear autoregressive moving average model with exogenous inputs or NARMAX model. This paper develops a practical algorithm for identifying NARMAX models based on radial basis

Oligoethylene Glycol Side‐Chain Engineering of Y6‐Derived Nonfullerene Acceptors for Thermally Induced Spontaneous Pseudo‐Planar Heterojunction Organic Photodetectors

Advanced Functional Materials, EarlyView.
OEG‐functionalized Y6‐derived acceptors induce thermally driven vertical phase separation, enabling pseudo‐planar heterojunction organic photodetectors. The resulting PM6:YTEG‐4F and PM6:YTEG‐4Cl organic photodetectors suppress dark current density by approximately 260‐fold and 210‐fold, respectively, while maintaining efficient photoresponse ...

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Characteristic polynomials of complex random matrix models [PDF]

, 2002
We calculate the expectation value of an arbitrary product of characteristic polynomials of complex random matrices and their hermitian conjugates. Using the technique of orthogonal polynomials in the complex plane our result can be written in terms of

Analytical formulas for polynomial coefficients in radial basis function interpolation

Mathematical Modelling and Analysis
Radial basis functions (RBF) are used in many areas, including interpolation and approximation, solution of partial differential equations, neural networks, and machine learning. RBFs are based on the sum of weighted kernel functions.

In Situ Magnetic Ordering and Microfabrication of Liquid Crystal Networks with Discretized Alignment

Advanced Functional Materials, EarlyView.
Miniaturizing liquid crystal network actuators typically demands costly laser writing or digital light processing. A low‐cost photolithography platform couples rotating photomasks with a Halbach magnetic array to discretize in‐plane molecular alignment down to 50 µm, producing programmable, light‐responsive grippers, checkerboards, and origami‐inspired

NARX-based nonlinear system identification using orthogonal least squares basis hunting [PDF]

, 2008
An orthogonal least squares technique for basis hunting (OLS-BH) is proposed to construct sparse radial basis function (RBF) models for NARX-type nonlinear systems.

Accelerated Discovery of Topological Spin Phase Diagrams in CrSBr Magnets Via High‐Throughput Optimization

Advanced Functional Materials, EarlyView.
Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

Going Next after “A Guide to Special Functions in Fractional Calculus”: A Discussion Survey

Mathematics
In the survey Kiryakova: “A Guide to Special Functions in Fractional Calculus” (published in this same journal in 2021) we proposed an overview of this huge class of special functions, including the Fox H-functions, the Fox–Wright generalized ...
