Oscillation of odd order neutral delay differential equation [PDF]
The authors consider the odd-order neutral delay differential equation (1) \((x(t) - \alpha x(t - \tau))^{(n)} + p(t) f(x(t - \sigma)) = 0\), where \(0 \leq \alpha < 1\), \(\tau, \sigma \in (0, \infty)\), \(p \in C ([0, \infty), (0, \infty))\), \(f \in C^1 (\mathbb{R}, \mathbb{R})\) such that \(f\) is increasing, \(xf(x) > 0\) for \(x \neq 0\).

Oscillation criteria for second-order neutral delay differential equations
New sufficient conditions for oscillation of second-order neutral half-linear delay differential equations are given. Our results essentially improve, complement and simplify a number of related ones in the literature, especially those from a recent ...

Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Asymptotic properties of the spectrum of neutral delay differential equations
Spectral properties and transition to instability in neutral delay differential equations are investigated in the limit of large delay. An approximation of the upper boundary of stability is found and compared to an analytically derived exact stability ...

Neutral stochastic functional differential equations with Levy jumps under the local Lipschitz condition [PDF]
In this paper, a general neutral stochastic functional differential equations with infinite delay and Lévy jumps (NSFDEwLJs) is studied. We investigate the existence and uniqueness of solutions to NSFDEwLJs at the phase space Cg under the local ...
