A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

open access: yesFEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

On a new class of operators from the Bloch-type space into H ∞ ( B X ) $H^{\infty}(\mathbb{B}_{X})$ of infinite dimensional bounded symmetric domains

open access: yesJournal of Inequalities and Applications
Under certain assumptions on the symbols, we give a necessary and sufficient condition for the boundedness of a new class of operators, T ψ 1 , ψ 2 , ψ 3 , φ $T_{\psi _{1}, \psi _{2}, \psi _{3}, \varphi}$ , mapping from the Bloch-type space B ( B X ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Multiple solutions for Kirchhoff type systems involving singular and critical nonlinearities

open access: yesElectronic Journal of Differential Equations
This article investigates the fractional singular Kirchhoff system $$\displaylines{ m(\mathcal{N}(\phi,\psi))\mathcal{L}_\mathcal{K}^p(\phi) =\lambda a(x)\phi^{-\gamma_1}+\frac{\theta_1}{p^\star_{N,s}}\phi^{\theta_1-1} \psi^{\theta_2} \quad \text{in ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Impulsive psi-Caputo fractional equations involving operator pairs in Banach spaces

open access: yesElectronic Journal of Differential Equations
This article studies two classes of \(\psi\)-Caputo fractional equations with impulsive conditions and operator pairs in Banach spaces: one is the impulsive Sobolev-type integro-differential equations with operator pairs on bounded intervals, the other ...

dynoGP: Deep Gaussian Processes for Dynamic System Identification

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

Bitlyan-Gol'dberg type inequality for entire functions and diagonal maximal term

open access: yesМатематичні Студії, 2020
In the article is obtained an analogue of Wiman-Bitlyan-Gol'dberg type inequality for entire $f\colon\mathbb{C}^p\to \mathbb{C}$ from the class $\mathcal{E}^{p}(\lambda)$ of functions represented by gap power series of the form $$ f(z)=\sum\limits_{k=0}^{

Density Measurement of Irradiated and Nonirradiated Zirconium Oxide by Ptychographic X‐Ray Computed Tomography (PXCT)

open access: yesAdvanced Engineering Materials, EarlyView.
Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.
