Controllability of nonlinear fractional Langevin delay systems

open access: yes, 2019
In this paper, we discuss the controllability of fractional Langevin delay dynamical systems represented by the fractional delay differential equations of order 0 < α,β ≤ 1.

The Evolutionary Properties on Solitary Solutions of Nonlinear Evolution Equations

open access: yesAdvances in Mathematical Physics, 2017
The evolution process of four class soliton solutions is investigated by basic calculus theory. For any given x, we describe the special curvature evolution following time t for the curve of soliton solution and also study the fluctuation of solution ...

Nonlinear DNA dynamics: Nonlinearity versus dispersion [PDF]

open access: yesApplied Mathematics and Computation, 2013
In the present paper we study the impact of dispersion and nonlinearity on DNA dynamics. We rely on the helicoidal Peyrard-Bishop model and use the fact that nonlinear DNA dynamics represents an interplay between nonlinearity and dispersion. We state that a dispersion coefficient and a coefficient of nonlinearity, existing in nonlinear Schrödinger ...

Bell Polynomials Approach Applied to (2 + 1)-Dimensional Variable-Coefficient Caudrey-Dodd-Gibbon-Kotera-Sawada Equation

open access: yesAbstract and Applied Analysis, 2014
The bilinear form, bilinear Bäcklund transformation, and Lax pair of a (2 + 1)-dimensional variable-coefficient Caudrey-Dodd-Gibbon-Kotera-Sawada equation are derived through Bell polynomials. The integrable constraint conditions on variable coefficients

A Review on a Class of Second Order Nonlinear Singular BVPs

open access: yesMathematics, 2020
Several real-life problems are modeled by nonlinear singular differential equations. In this article, we study a class of nonlinear singular differential equations, explore its various aspects, and provide a detailed literature survey. Nonlinear singular

Nonlinear spillover effect of us monetary policy uncertainty on China’s systematic financial risks

open access: yesJournal of Business Economics and Management, 2022
Monetary policy uncertainty (MPU) not only imposes a great impact on the systematic financial risks of a country but also generates a significant spillover effect on countries having close economic exchanges with the former under the background of global

Behavior of strengthened concrete beams damaged by thermal shock [PDF]

open access: yesИнженерно-строительный журнал, 2020
In the last two decades, using of Carbon Fiber Reinforced Polymers (CFRP) in strengthening of deficient reinforced concrete structural elements has been increased due to their ease of installation, low invasiveness, high corrosion resistance, and high ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Gender Matters: Nonlinear Relationships Between Heart Rate Variability and Depression and Positive Affect

open access: yesFrontiers in Neuroscience, 2021
Vagally mediated heart rate variability (vmHRV), a measure of the parasympathetic nervous system’s control over the heart, is often negatively related to maladaptive emotional outcomes.
