First principles density functional theory based calculations have been performed to investigate the strain and temperature induced tunability of thermoelectric properties monolayer (ML) MoS2. Modifications in electronic phononic transport properties, under two anisotropic uniaxial strains along armchair (AC) zigzag (ZZ) directions, explored detail. Considering intrinsic carrier-phonon scatteri...

is known as Hutchinson’s equation, if r and K are positive constants and h(t) = t− τ for a positive constant τ. Hutchinson’s equation has been investigated by several authors (see, e.g., [13, 14, 18, 23]). Delay logistic equation (1.1) was studied by Gopalsamy and Zhang [7, 25] who gave sufficient conditions for the oscillation and the nonoscillation of (1.1). Publications [1, 2, 3, 4, 5, 6, 10...

The existence of positive heteroclinic solutions is proven for a class of scalar population models with one discrete delay. Traveling wave solutions for scalar delayed reaction-diffusion equations are also obtained, as perturbations of heteroclinic solutions of the associated equation without diffusion. As an illustration, the results are applied to the Nicholson’s blowflies equation with diffu...

By means of Riccati transformation technique, we establish some new oscillation criteria for the second-order Emden-Fowler delay dynamic equations rxΔ Δ t p t x τ t 0 on a time scale T; here γ is a quotient of odd positive integers with r and p as real-valued positive rd-continuous functions defined on T. Our results in this paper not only extend the results given in Agarwal et al. 2005 , Akin-...

We present an approach for the analytical treatment of excitable systems with noise-induced dynamics in the presence of time delay. An excitable system is modeled as a bistable system with a time delay, while another delay enters as a control term taken after [Pyragas 1992] as a difference between the current system state and its state τ time units before. This approach combines the elements of...

By means of Riccati transformation technique, we establish some new oscillation criteria for the second-order nonlinear delay dynamic equations r t xΔ t γ Δ p t f x τ t 0 on a time scale T; here γ > 0 is a quotient of odd positive integers with r and p real-valued positive rdcontinuous functions defined on T. Our results not only extend some results established by Hassan in 2008 but also unify ...

Oscillatory and asymptotic behaviour of the solutions of a class of nonlinear first order neutral delay differential equations with positive and negative coefficients of the form (E 1) d dt [y(t) + p(t)y(t − τ)] + f 1 (t)G 1 (y(t − σ 1)) − f 2 (t)G 2 (y(t − σ 2)) = g(t) and (E 2) d dt [y(t) + p(t)y(t − τ)] + f 1 (t)G 1 (y(t − σ 1)) − f 2 (t)G 2 (y(t − σ 2)) = 0 are studied under various ranges ...

A modified Leslie-Gower predator-prey system with two delays is investigated. By choosing τ 1 and τ 2 as bifurcation parameters, we show that the Hopf bifurcations occur when time delay crosses some critical values. Moreover, we derive the equation describing the flow on the center manifold; then we give the formula for determining the direction of the Hopf bifurcation and the stability of bifu...
