In this paper, we propose a token-based fully distributed algorithm with token-asking method for

Distributed Mutual Exclusion (DME) in a computer network composed of N nodes that communicate by

message exchanges. The main goal...

Mutualistic interaction between aphids and ants is one of the classical examples of mutualism. The current study was carried out during 2013-2014 in Golestan province, North-eastern Iran, to investigate the myrmecophilous aphids...

Food webs centered on aphids contain networks of species, some directly related to prey characteristics, others mediated via the characteristics of the host plant. These tritrophic interactions can be even more extensive ...

In this paper, by using the notion of negativity, we study the degree of entanglement of a two-level atom interacting with a quantized radiation field, described by the Jaynes–Cummings model (JCM). We suppose that initially ...

Ant-aphid mutualism may increase or decrease plant yield. This depends on the relative cost of damage by ant-tended aphids versus the relative benefit of ant suppression of other (non-aphid) herbivores and associated yield losses. To evaluate...

Let Pr_nCom(G) denotes the probability that a randomly ordered

n-tuples of elements in a finite group G be a mutually

commuting n-tuples. We aim to generalize the above concept to a

compact topological group which generally...
