A DETERMINISTIC APPROACH TO THE SYNCHRONIZATION OF NONLINEAR CELLULAR AUTOMATA
De Abreu J., García P., García J. Advances in Complex Systems; 20 (4-5, 1750006) 2017. 10.1142/S0219525917500060.
In this work, we introduce a deterministic scheme of synchronization of nonlinear cellular automata with chaotic behavior, connected through a master-slave coupling. By using a definition of Boolean derivative, we utilize the linear approximation of the cellular automata rules to design a deterministic and simple coupling function that ensures synchronization. Our results show that it is possible to synchronize nonlinear chaotic cellular automata using a deterministic coupling function that does not introduce into the slave all the information about the state of the master. © 2017 World Scientific Publishing Company.

Microstructure and ionic conductivity of LLTO thin films: Influence of different substrates and excess lithium in the target
Aguesse F., Roddatis V., Roqueta J., Garcia P., Pergolesi D., Santiso J., Kilner J.A. Solid State Ionics; 272: 1 - 8. 2015. 10.1016/j.ssi.2014.12.005. IF: 2.561
The deposition of single phase Li3xLa2/3 - xTiO3 (LLTO) thin films remains very challenging. The growth of the perovskite phase is in competition with the insulating La2Ti2O7 phase when prepared at high oxygen pressure by PLD. Nevertheless, we have achieved epitaxial growth of LLTO on different (001) oriented substrates such as LaAlO3, SrTiO3 and MgO despite a large lattice mismatch of up to + 8.8%. We also determined the percentage of lithium excess in the target necessary to reach a maximum ionic conductivity. However, the presence of the blocking La2Ti2O7 phase strongly hinders the lithium ion migration and reduces the total conductivity compared to bulk properties. © 2014 Elsevier B.V.
