the modeling investigation in this paper discusses the system level effects of a toxicant on a three species food chain system. in the models, we have assumed that the presence of top predator reduces the predatory ability of the intermediate predator. the stability analysis of the models is carried out and the sufficient conditions for the existence and extinction of the populations under the ...

background and aims: inhibition of viral growth in coinfected cells with two different viruses has been described. this phenomenon known as viral interference can occur in several virus host systems such as interference of enterovirus infection on poliovirus vaccine strains. in this study we superinfected reovirus infected hela cells with poliovirus to determine if poliovirus can replicate in s...

In this paper we investigate the performance of MIMO systems in co-channel interference. We present a way of explicitly examining the effect of interference on the MIMO sub-channel gains. Using this, we derive upper and lower asymptotic bounds on capacity with many interferers and in high interference-to-noise ratio. Simulation results are presented for these bounds and for the performance of M...
