Uniform Stability of Discrete Delay Systems and Synchronization of Discrete Delay Dynamical Networks via Razumikhin Technique

IEEE Transactions on Circuits and Systems I: Regular Papers, 2008
In this paper, we consider discrete delay systems and obtain conditions for global uniform exponential stability. Our approach is based on the use of the Razumikhin technique and the Lyapunov function method. In the second part of the paper, we use our stability results to derive exponential synchronization criteria for discrete dynamical networks with

Stabilizing effect of delay distribution for a class of second-order systems without instantaneous feedback [PDF]

, 2009
In many situations in physics, engineering and biology time delays arise naturally due to the time needed to transport information from one part of the system to another and/or to react to incoming information. When differential equations are used in the

Generalized Ulam’s Stability of Delayed Discrete System With Second-Order Differences

Discrete Dynamics in Nature and Society
This work explores generalized Ulam-type stability for a family of time-lag discrete systems governed by two-order difference operators. First and foremost, we put forward strict mathematical formulations of Hyers–Ulam-based generalized stability adapted

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...
