We study numerically domain growth and interface fluctuations in oneand two-dimensional lattice systems composed of four species that interact in a cyclic way. Particle mobility is implemented through exchanges of particles located on neighboring lattice sites. For the chain we find that the details of the domain growth strongly depend on the mobility, with a higher mobility yielding a larger e...

We study, within the framework of game theory, the properties of a spatially distributed population of both predators and preys that may hunt or defend themselves either isolatedly or in group. Specifically, we show that the properties of the spatial Lett-Auger-Gaillard model, when different strategies coexist, can be understood through the geometric behavior of clusters involving four effectiv...

A class of cyclic balanced designs with ten test-hills is introduced; these designs can be repeated cyclically any number of times up to the requirement of the experimenter and subject to the availability of experimental material. The designs are balanced with respect to first order nearest neighbours and there are 26 isomorphism classes of such designs. The designs are suitable for de Wit repl...

In this talk, we present the role of a local effect in the coexistence of mobile populations whose interactions are governed by a rock-paper-scissors game in spatially extended ecosystems. With different values of relative parameter between migration and local habitat suitability on large sizes, we do some simulations and find that coexistence is broken near the critical mobility Mc, but is occ...

Previously designed cyclic peptide antagonist c[YYDEGLEE]-NH2 disrupts the interaction between vascular endothelial growth factor (VEGF) and its receptors (VEGFRs). It represents a promising tool in the fight against cancer and age-related macular degeneration. We described in this paper the optimization of the lead peptide by C-terminal modification. A new strategy for the synthesis of cyclic ...

We are becoming increasingly dependent on large interconnected networks for the control of our resources. One important issue is resource protection strategies in the event of failures and/or attacks. To address this issue we investigated the eeectiveness of evolving nite-state machine (FSM) strategies for winning against an adversary in a challenging Competition for Resources simulation. Altho...

This paper summarized our present view on the mechanism of cyclic electron flow in C3 plants. We propose that cyclic and linear pathways are in competition for the reoxidation of the soluble primary PSI acceptor, Ferredoxin (Fd), that freely diffuses in the stromal compartment. In the linear mode, Fd binds ferredoxin-NADP-reductase and electrons are transferred to NADP+ and then to the Benson a...

Competitive tournaments appear in sports, politics, population ecology, and animal behavior. All of these fields have developed methods for rating competitors ranking them accordingly. A tournament is intransitive if it not consistent with any ranking. Intransitive contain rock-paper-scissors type cycles. The discrete Helmholtz--Hodge decomposition (HHD) well adapted to describing tournaments. ...
