Machine-to-machine (M2M) communication is a system that allows information interaction between machines independently and automatically through a network without human intervention.However, when massive M2M devices access the network, they can quickly scramble preambles, and induce significant network congestion.Specially, when the massive M2M devi
Sugarcane smut caused by Sporisorium scitamineum is one of the most severe fungal diseases worldwide.In this study, a cross was made between a smut-resistant variety YT93-159 and a smut-susceptible variety ROC22, and 312 progenies were obtained.Two bulks of progenies were then constructed, one consisted of 27 highly smut resistant progenies and the
