Dear editor,rnSafeguarding physical-layer non-orthogonal multiple access(NOMA)transmissions using relays has been received widespread attention[1,2].However,a relay may be data-level untrusted and serve as an eavesdropper to decode its forwarded messages.Hence,information security needs to be guaranteed if an untrusted relay is involved.

Dear editor,rnThis study researches the pth moment exponential stability of general discrete-time nonlinear stochastic system xk+1=Fk(xk,ωk),Fk(0,?)≡ 0.(1)Since Lyapunov initiated his stability theory,stability anal-ysis has been one of the most important
Dear editor,rnWith the popularity of computers and networks in control systems,sampled-data control is becoming increasingly im-portant and has attracted intensive attention over the past decades[1,2].However,for systems with serious uncer-tainties(withou
