Ti3C2Tx MXene/Silver Composite Foams For Lightweight, High‐Performance Electromagnetic Interference Shielding and Joule Heating

Advanced Materials Interfaces, EarlyView.
Ultrathin MXene/EMF composite foams achieve a specific shielding efficiency of 749.6 dB.dB·cm3$\mathrm{dB}\cdot {\mathrm{cm}}^{3}$/g, while the silver‐enhanced MXene/Ag/EMF reaches 81.4 dB shielding effectiveness at just 1.0 mm thickness. Both composites exhibit rapid Joule heating, retain stability up to 250∘C$^\circ{\rm C}$, and withstand 1000 ...

On the global attractivity controversy for a delay model of hematopoiesis [PDF]

Applied Mathematics and Computation, 2007
In this short paper it is shown, with the help of the general theory of monotone systems, and under some specific hypotheses for function \(f\) that the trivial equilibrium of the delayed differential equation \[ x'(t)= -\mu x(t) +f(x(t-r)) \] is stable and attracts a large subset of positive solutions, for all the values of the delay \(r\).

Global attractivity in a recursive sequence [PDF]

Applied Mathematics and Computation, 2004
The authors consider the rational difference equation \[ x_n = (ax_{n-1} - bx_{n-2})/(c+x_{n-2}) \] with \(a\), \(b\), \(c>0\). The following subjects are addressed: local asymptotic stability of the two equilibria (stability by the first approximation); invariant intervals (``manifolds''); global attractivity of the equilibria.

Global attractivity in a rational recursive sequence

Applied Mathematics and Computation, 2003
The authors investigate the periodic character, invariant intervals and the global attractivity of all positive solutions of the nonlinear difference equation \[ x_{n+1}=\frac{\alpha+\beta x_{n}}{\gamma-x_{n-1}}, \quad n=0,1,\dots, \] where \(\alpha\geq 0\) and \(\beta,\gamma>0.\) It is shown that the positive equilibrium of the equation is a global ...

Global attractivity in nicholson's blowflies

Applicable Analysis, 1992
We established sufficient conditions for the global attractivity of the positive equilibrium of the delay differential equation [Ndot](t) ≡ −δN(t) + PN(t–τ)e−aN(t–τ) which was used by Gurney, Blythe and Nisbet [1] in describing the dynamics of Nicholson's ...

Global attractivity of Cohen–Grossberg model with finite and infinite delays [PDF]

Journal of Mathematical Analysis and Applications, 2006
In this paper, we have studied the global attractivity of the equilibrium of Cohen–Grossberg model with both finite and infinite delays. Criteria for global attractivity are also derived by means of Lyapunov functionals.
