      A polynomial alternative to unbounded environment for tissue P systems with cell division  [Article]

      Pérez Jiménez, Mario de Jesús; Riscos Núñez, Agustín; Rius Font, Miquel; Romero Campero, Francisco José (Taylor and Francis, 2013)
      The standard definition of tissue P systems includes a special alphabet whose elements are assumed to appear in the initial configuration of the system in an arbitrarily large number of copies. These objects reside in ...

      A Study of the Robustness of the EGFR Signalling Cascade Using Continuous Membrane Systems  [Chapter of Book]

      Pérez Jiménez, Mario de Jesús; Romero Campero, Francisco José (Springer, 2005)
      Many approaches to anticancer treatment have had a limited success. A fundamental hurdle to cancer therapy is the robustness of the signalling networks involved in tumourgenesis. The complexity of net- works of biological ...

      A uniform solution to SAT using membrane creation  [Article]

      Gutiérrez Naranjo, Miguel Ángel; Pérez Jiménez, Mario de Jesús; Romero Campero, Francisco José (Elsevier, 2007)
      In living cells, new membranes are produced basically through two processes: mitosis and autopoiesis. These two processes have inspired two variants of cell-like membrane systems, namely P systems with active membranes ...
