We propose a model for cyclically competing species on continuous space and investigate the effect of the interplay between the interaction range and mobility on coexistence. A transition from coexistence to extinction is uncovered with a strikingly nonmonotonic behavior in the coexistence probability. About the minimum in the probability, switches between spiral and plane-wave patterns arise. ...

Until the year 2000, there was no specific statute enacted in Jordan that regulates unfair competition. In the year 2000, the Jordanian Unfair Competition Law No. 15 of 2000 was enacted. The Law deals with the issue of unfair competition in a very generic way. In addition to the Jordanian Unfair Competition Law, the principal statutory source of protection is implemented through the general rul...

The regulatory subunit (R) of CAMP-dependent protein kinase from bovine heart contains two intrachain CAMP binding sites which differ in their rate of cyclic nucleotide dissociation and specificity of cyclic nucleotide analog binding. Competition studies indicate that different Site 1-directed cyclic nucleotide analogs with 8-position modifications markedly inhibit each other for binding to R b...

Defining the role of T-cell avidity and killing efficacy in forming immunological response(s), leading to relapse-remission and autoantibody release in autoimmune type 1 diabetes (T1D), remains incompletely understood. Using competition-based population models of T- and B-cells, we provide a predictive tool to determine how these two parametric quantities, namely, avidity and killing efficacy, ...

We introduce a population model for species under cyclic competition. This model allows individuals to coexist and interact on single cells while migration takes place between adjacent cells. In contrast to the model introduced by Reichenbach, Mobilia, and Frey [Reichenbach, Mobilia, and Frey, Nature (London) 448, 1046 (2007)], we find that the emergence of spirals results in an ambiguous behav...
