Some hyperstability results of a p-radical functional equation related to quartic mappings in non-archimedean Banach spaces

open access: yes, 2021
The aim of this paper is to introduce and solve the following p-radical functional equation related to quartic mappings where f is a mapping from R into a vector space X and p ≥ 3 is an odd natural number.

A Hyperstability/Multiobjective Optimization Approach for Active Flexible Structures

open access: yes, 1991
A controller design method is proposed as a combination of the so-called hyperstability theory and the multiobjective optimization approach. In this combination the hyperstability theory serves to specify a computationally tractable controller stucture ...

Hyperstability in Electrofishing Catch Rates of Common Carp and Bigmouth Buffalo [PDF]

open access: yes, 2022
Electrofishing catch per unit effort (CPUE) can be an effective index of relative abundance when CPUE is proportional to population density. However, the relationship between fish catch rates and density can be variable and not proportional because ...

Orthogonally Fixed Points and (m, m)-Hom-Derivation Equations

open access: yesJournal of Mathematics, 2022
In this paper, we introduce the concept of m-Hom-m-derivation (briefly (m, m)-Hom-derivation) equations in orthogonally Banach algebras. We use the orthogonally fixed point to investigate the hyperstability of (m, m)-Hom-derivation equations.

Orthogonally C∗-Ternary Jordan Homomorphisms and Jordan Derivations: Solution and Stability

open access: yesJournal of Mathematics, 2022
In this work, by using some orthogonally fixed point theorem, we prove the stability and hyperstability of orthogonally C∗-ternary Jordan homomorphisms between C∗-ternary Banach algebras and orthogonally C∗-ternary Jordan derivations of some functional ...

About a Class of Positive Hybrid Dynamic Linear Systems and an Associate Extended Kalman-Yakubovich-Popov Lemma

open access: yesDiscrete Dynamics in Nature and Society, 2017
This paper formulates an “ad hoc” robust version under parametrical disturbances of the discrete version of the Kalman-Yakubovich-Popov Lemma for a class of positive hybrid dynamic linear systems which consist of a continuous-time system coupled with a ...

A Space Function Approach to the Hyperstability and the Average Hyperstability of Distributed Systems With Space-Varying Linear Parts and Time-Varying Gains

open access: yes, 1975
We propose an extension of the Popov’s hyperstability theory which applies to a class of single-control distributed systems in which the linear part depends explicitely upon the distributed parameter, z. The nonlinearness of these systems is expressed by

Generalized Hyers–Ulam Stability of the Additive Functional Equation

open access: yesAxioms, 2019
We will prove the generalized Hyers–Ulam stability and the hyperstability of the additive functional equation f(x1 + y1, x2 + y2, …, xn + yn) = f(x1, x2, … xn) + f(y1, y2, …, yn).

Visualizing Specific Tubulin Isotypes and Pathogenic Variants in Cellular Microtubule Arrays

open access: yesCytoskeleton, EarlyView.
ABSTRACT Eukaryotic cells depend on dynamic microtubule arrays to execute a wide range of functions vital for life. These microtubule filaments are formed through the polymerization of α/β‐tubulin proteins, which can be generated from numerous tubulin genes, or isotypes.
