WebThe frog model on trees with drift Döbler and Pfeifroth showed that the frog model is recurrent on Zd for d 2 so long as Elog(d+1)=2 + = 1[DP14]. It was open for some time … WebWe provide a uniform upper bound on the minimal drift so that the one-per-site frog model on a d d -ary tree is recurrent. To do this, we introduce a subprocess that couples across …

Web14 Apr 2024 · Artificial light at night (ALAN) and noise pollution have been shown to affect urban wildlife everywhere, but little is known about the effects of these variables on urban frogs. Our objective was to model the effects of ALAN and noise pollution (as well as a suite of other habitat variables) on site occupancy of gray treefrogs (Hyla versicolor) and green … WebKeywords: Frog model; transience; drift; coupling 2010 Mathematics Subject Classification: Primary 60J80 Secondary 60K35 1. Introduction The frog model is a system of interacting random walks on a rooted graph. It begins with a single 'active' frog at the root and some distribution of sleeping frogs (either random or deterministic) at the ... Web1 Aug 2024 · In this model, active frogs move toward the root with probability p or otherwise move to a uniformly chosen child vertex. Whenever a site is visited for the first time, a new active frog is introduced at the site. We are interested in the minimal drift pd p d so that the frog model is recurrent. is dramamine safe in pregnancy
