A new two-party quantum key agreement (QKA) protocol is proposed based on four-qubit
cluster states. Encoded four-qubit cluster states can be transmitted directly by means of …

We investigate the dynamics of a nonautonomous stochastic SIS epidemic model with
nonlinear incidence rate and double epidemic hypothesis. By constructing suitable …

This paper proposes two new stochastic non-autonomous SEIS epidemic dynamical models
with latent and active patients. For the non-autonomous periodic system, we first obtain the …

This paper proposes a new delayed stochastic epidemic model with double epidemic
hypothesis and a general nonlinear response function. The main purpose is to explore the …

This paper considers a high‐dimensional stochastic SEIQR (susceptible‐exposed‐infected‐
quarantined‐recovered) epidemic model with quarantine‐adjusted incidence and the …

This paper is concerned with the stability problem for a class of neutral type singular systems
with time-varying delay. The considered systems contain delays both in their state and in …

This paper proposes two stochastic SIQS epidemic models with periodic parameters and
Markov switching. We first prove that the stochastic non-autonomous periodic system has a …

This paper is concerned with the dynamic characteristics of the SIQR model with media
coverage and regime switching. Firstly, the existence of the unique positive solution of the …

This paper proposes a novel impulsive stochastic nonautonomous chemostat model with the
saturated and bilinear growth rates in a polluted environment. Using the theory of impulsive …

We develop an adaptive dynamic programming (ADP) approach to deal with the linear-
quadratic (LQ) optimal control problem with unknown discrete-time mean-field stochastic …
