For a random walk on finitely generated group G we obtain generalization of classical inequality Ancona. We deduce as corollary that the identity map extends to continuous equivariant surjection from Martin boundary Floyd boundary, with preimages conical points being singletons. This provides new results for compactifications relatively hyperbolic groups.

Expressed sequence tags (ESTs) from the Antarctic green algae Pyramimonas gelidicola were analyzed to obtain molecular information on cold acclimation of psychrophilic microorganisms. A total of 2,112 EST clones were sequenced, generating 222 contigs and 219 singletons, and 200 contigs and 391 singletons from control (4 degrees C) and cold-shock conditions (-2 degrees C), respectively. The comp...

The family of rational subsets of a direct product of free monoids Σ∗ 1×. . .×Σ ∗ n (the rational relations) is not closed under Boolean operations, except when n = 1 or when all Σi’s are empty or singletons. In this paper we introduce the family of generalized rational subsets of an arbitrary monoid as the closure of the singletons under the Boolean operations, concatenation and Kleene star (j...

Twin pregnancies demonstrate a 2–3-fold higher chance of developing PE compared to singletons, and recent evidence has demonstrated that the sFLT1/PIGF ratio is strongly associated with PE, adverse pregnancy outcomes, as well imminent deliveries due complications. The primary objective this systematic review was summarise available data on levels sFLT1, PlGF their ratios in twin investigate ass...

Abstract Passive acoustic monitoring is a promising method for surveying wildlife populations that are easier to detect acoustically than visually. When animal vocalisations can be uniquely identified on an array of sensors, the potential exists estimate population density through spatial capture–recapture (ASCR). However, sound classification imperfect, and in some situations, high proportion ...

In this paper we prove that a recent Bayesian approximation of belief functions, the relative belief of singletons, meets a number of properties with respect to Dempster’s rule of combination which mirrors those satisfied by the relative plausibility of singletons. In particular, the related operator commutes with Dempster’s sum of plausibility functions, while the relative belief perfectly rep...
