Recently, employing an in-network data aggregation forest has been proposed to achieve energy saving in wireless sensor networks with multiple sinks. The construction of an in-network maximum-lifetime data aggregation forest was shown NP-complete, and only one centralized algorithm in the literature was designed to solve it. The centralized algorithm(More)
Viral synergism is caused by co-infection of two unrelated viruses, leading to more severe symptoms or increased titres of one or both viruses. Synergistic infection of phloem-restricted poleroviruses and umbraviruses has destructive effects on crop plants. The mechanism underlying this synergy remains elusive. In our study, synergism was observed in(More)
