Asymptotic behaviour of neutral differential equations of third-order with negative term
Electronic Journal of Qualitative Theory of Differential Equations, 2016 We derive new comparison theorems and oscillation criteria for neutral differential equations of third order with negative term. We show that one can deduce oscillation criteria for the equation with negative term from those for the equation with ...

Electronic Journal of Differential Equations, 2020 We consider a class of nonlinear time-varying delay systems of neutral type differential equations with periodic coefficients in the linear terms, $$\begin{aligned} \frac{d}{dt} y(t) &= A(t) y(t) + B(t) y(t-\tau(t)) + C(t) \frac{d}{dt} y(t-\tau(t ...

Positive Periodic Solution for Neutral-Type Integral Differential Equation Arising in Epidemic Model
Mathematics, 2023 This paper is devoted to investigating a class of neutral-type integral differential equations arising in an epidemic model. By using Mawhin’s continuation theorem and the properties of neutral-type operators, we obtain the existence conditions for ...

Ulam–Hyers Stability of Fractional Difference Equations with Hilfer Derivatives
Fractal and FractionalThis paper investigates the Ulam–Hyers stability of both linear and nonlinear delayed neutral Hilfer fractional difference equations. We utilize the nabla Laplace transform, known as the N-transform, along with a generalized discrete Gronwall inequality ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Oscillation Conditions for Third-Order Delay Differential Equations with Neutral-Type Term
MathematicsIn this work, we adopted an approach similar to that of Chatzarakis’, by transforming the oscillation analysis of third-order differential equations into an equivalent first-order problem.

Attractivity for neutral functional differential equations
Discrete & Continuous Dynamical Systems - B, 2013 We study the long term dynamics of non-autonomous functional di fferential equations. Namely, we establish existence results on pullback attractors for non-linear neutral functional di erential equations with time varying delays. The two main results di er in smoothness properties of delay functions.
