We consider growing random networks {Gn}n≥1 where, at each time, a new vertex attaches itself to collection of existing vertices via fixed number m≥1 edges, with probability proportional function f (called attachment function) their degree. It was shown in [BB21] that such network models exhibit two distinct regimes: (i) the persistent regime, corresponding ∑i=1∞f(i)−2<∞, where top K maximal de...

in order to determine the critical period of weed control (cpwc) in corn (zea mays l.), an experiment was carried out in a randomized complete blocks design with 14 treatments and three replications during 2013 growing season in the nahavand climatic conditions. two series of the treatments including weed-free and weed-infested were applied in the regular time distances of 10, 20, 30, 40, 50 an...
