A NEW CHARACTERIZATION OF 𝑞-CHEBYSHEV POLYNOMIALS OF THE SECOND KIND

open access: yesПроблемы анализа
In this work, we introduce the notion of $\cal{U}_{(q, \mu)}$-classical orthogonal polynomials, where $\cal{U}_{(q, \mu)}$ is the degree raising shift operator defined by $\cal{U}_{(q, \mu)}$ $:= x(xH_q + q^{-1}I_{\cal{P}}) + \mu H_q$, where $\mu$ is a

Phase‐Retrieved High‐Throughput Multi‐Channel Simultaneous Surface Plasmon Resonance Detection

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a new phase‐retrieval high‐throughput multi‐channel simultaneous SPR detection framework. By integrating an objective lens‐based coupling system with a rotation‐based ePIE (r‐ePIE) phase retrieval on the back focal planes, this framework significantly reduces the minimum required detection area to reveal localized information.

Korobov’s controllability function method via orthogonal polynomials on [0,∞)

open access: yesVisnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i Mehanika
Given a controllable system described by ordinary or partial differential equations and an initial state, the problem of finding a set of bounded positional controls that transfer the initial state to another state, not necessarily an equilibrium point ...

Biaxial Gay‐Berne Liquid Crystal Elastomer

open access: yesMacromolecular Chemistry and Physics, EarlyView.
Large‐scale Monte Carlo molecular simulations show that long‐range biaxial orientational order can exist in swollen thermotropic main‐chain liquid crystal elastomers, and that it is accompanied by a spontaneous biaxial elastic deformation. Biaxial ordering is also reflected in deuterium magnetic resonance spectra and scattered X‐ray intensity patterns ...

Exploring Thermal and Mechanical Strains During Laying Down Process in Fused Filament Fabrication

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study analyzes strain evolution and thermal behavior during FFF of PLA using strain gauges and infrared imaging. Microstrain levels depend on printing conditions, with adhesion‐induced compression during cooling and peak strains in early layers. Microtomography shows minimal porosity, while thermal imaging reveals rapid heat penetration, strong ...

On the Limit from q-Racah Polynomials to Big q-Jacobi Polynomials

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
A limit formula from q-Racah polynomials to big q-Jacobi polynomials is given which can be considered as a limit formula for orthogonal polynomials.
