<p style='text-indent:20px;'>In this study, we consider a Lotka–Volterra reaction–diffusion–advection model for two competing species under homogeneous Dirichlet boundary conditions, describing hostile environment at the boundary. In particular, deal with case in which one diffuses constant rate, whereas other has rate diffusion directed movement toward better habitat heterogeneous lethal...

This study focuses on the quasisynchronization problem for reaction–diffusion neural networks (RDNNs) in presence of deception attacks. Under attacks, a time–space sampled-data (TSSD) control mechanism is proposed RDNNs. Compared with traditional strategies, can not only save network bandwidth but also improve cybersecurity communications. Inspired by Halanay’s inequality, new inequality propos...

the synthesis of functionalized 2-oxo-2h-coumarin derivatives has been studied by a one-pot reaction of o-hydroxybenzaldehyde, ethyl 2-bromoacetate and triphenylphosphine in the presence of catalytic amount of triethyl amine in etoac, water or under solvent free conditions. we have found the best results obtained under solvent free condition.
