The finding and researching algorithm for potentially oscillating enzymatic systems

open access: yesВавиловский журнал генетики и селекции, 2021
Many processes in living organisms are subject to periodic oscillations at different hierarchical levels of their organization: from molecular-genetic to population and ecological. Oscillatory processes are responsible for cell cycles in both prokaryotes

A Chimera Oscillatory State in a Globally Delay-Coupled Oscillator Network

open access: yesComplexity, 2020
Oscillatory behavior is absolutely necessary for the normal functioning of various organisms and their performance. Therefore, it is necessary to protect the oscillatory behavior in an aging network which consists of oscillatory and nonoscillatory nodes.

Oscillatory behavior of even-order nonlinear differential equations with a sublinear neutral term [PDF]

open access: yesOpuscula Mathematica, 2019
The authors present a new technique for the linearization of even-order nonlinear differential equations with a sublinear neutral term. They establish some new oscillation criteria via comparison with higher-order linear delay differential inequalities ...

On the Positive Decreasing Solutions of Half-Linear Delay Differential Equations of Even Order

open access: yesMathematics, 2023
In this paper, we derive new properties for the decreasing positive solutions of half-linear delay differential equations of even order. The positive-decreasing solutions have a great influence on the study of qualitative properties, which include ...

On the Oscillatory Behavior of a Class of Fourth-Order Nonlinear Differential Equation

open access: yesSymmetry, 2020
In this work, we study the oscillatory behavior of a class of fourth-order differential equations. New oscillation criteria were obtained by employing a refinement of the Riccati transformations.

Variability and stability of large-scale cortical oscillation patterns [PDF]

open access: yesNetwork Neuroscience, 2018
Individual differences in brain organization exist at many spatiotemporal scales and underlie the diversity of human thought and behavior. Oscillatory neural activity is crucial for these processes, but how such rhythms are expressed across the cortex ...

New Results for the Investigation of the Asymptotic Behavior of Solutions of Nonlinear Perturbed Differential Equations

open access: yesAxioms, 2023
This study focuses on investigating the oscillatory properties of a particular class of perturbed differential equations in the noncanonical case. Our research aims to establish more effective criteria for evaluating the absence of positive solutions to ...

Oscillatory behavior of light in the composite Goos-Hänchen shift [PDF]

open access: yes, 2017
For incidence in the critical region, the propagation of gaussian lasers through triangular dielectric blocks is characterized by the joint action of angular deviations and lateral displacements. This mixed effect, known as composite Goos-Haenchen shift,

Creep and Large-amplitude Oscillatory Shear Behavior of Whey Protein Isolate/κ-carrageenan Gels

open access: yesApplied Rheology, 2012
Dynamic oscillatory and creep tests are two common rheological methods used to determine viscoelastic properties. In the food industry, these tests are generally performed in the linear viscoelastic region, providing information on food structure and ...
