BACKGROUND: Apis mellifera stings are a problem for public health worldwide, particularly in Latin America due to the aggressiveness of its Africanized honeybees. Massive poisoning by A. mellifera venom (AmV) affects mainly the cardiovascular system, and several works have...

Two-dimensional Ising transition through a technique from two-state opinion-dynamics models.

Physical review. E, Statistical, nonlinear, and soft matter physics

Galam S, Martins AC.
PMID: 25679571
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Jan;91(1):012108. doi: 10.1103/PhysRevE.91.012108. Epub 2015 Jan 06.

The Ising ferromagnetic model on a square lattice is revisited using the Galam unifying frame (GUF), set to investigate two-state opinion-dynamics models. When combined with Metropolis dynamics, an unexpected intermediate "dis/order" regime is found with the coexistence of two...
