      Extended Spiking Neural P systems with Excitatory and Inhibitory Astrocytes  [Presentation]

      Binder, Aneta; Freund, Rudolf; Oswald, Marion; Vock, Lorenz (Fénix Editora, 2007)
      We investigate an extended model of spiking neural P systems incorporating astrocytes and their excitatory or inhibitory influence on axons between neurons. Using very restricted variants of extended spiking neural P ...

      Extended Spiking Neural P Systems with White Hole Rules  [Presentation]

      Alhazov, Artiom; Freund, Rudolf; Ivanov, Sergiu; Oswald, Marion; Verlan, Sergey (Fénix Editora, 2015)
      We consider extended spiking neural P systems with the additional possibility of so-called \white hole rules", which send the complete contents of a neuron to other neurons, and we show how this extension of the original ...

      Input-Driven Tissue P Automata  [Presentation]

      Alhazov, Artiom; Freund, Rudolf; Ivanov, Sergiu; Oswald, Marion; Verlan, Sergey (Universidad de Sevilla, Escuela Técnica Superior de Ingeniería Informática, 2018)
      We introduce several variants of input-driven tissue P automata where the rules to be applied only depend on the input symbol. Both strings and multisets are considered as input objects; the strings are either read from ...

      Multiset Random Context Grammars, Checkers, and Transducers  [Presentation]

      Cavaliere, Matteo; Freund, Rudolf; Oswald, Marion; Sburlan, Dragos (Fénix Editora, 2006)
      We introduce a general model of random context multiset grammars as well as the concept of multiset random context checkers and transducers. Our main results show how recursively enumerable sets of finite multisets can ...

      P Systems for Social Networks  [Presentation]

      Csuhaj Varjú, Erzsébet; Gheorgue, Marian; Vaszil, György; Oswald, Marion (Fénix Editora, 2011)
      We introduce some variants of P systems that mimic the behaviour of social networks and illustrate some of the characteristics of them. Other concepts related to social networks are discussed and suitable classes of P ...

      P Systems with Antiport Rules for Evolution Rules  [Presentation]

      Freund, Rudolf; Oswald, Marion (Fénix Editora, 2004)
      We investigate a variant of evolution-communication P systems where the computation is performed in two substeps. First, all possible an- tiport rules are applied in a non-deterministic, maximally parallel way, ...

      Partial Versus Total Halting in P Systems  [Presentation]

      Alhazov, Artiom; Freund, Rudolf; Oswald, Marion; Verlan, Sergey (Fénix Editora, 2007)
      We consider a new variant of the halting condition in P systems, i.e., a computation in a P system is already called halting if not for all membranes a rule is applicable anymore at the same time, whereas usually a ...

      Sequential P Systems with Unit Rules and Energy Assigned to Membranes  [Presentation]

      Freund, Rudolf; Leporati, Alberto; Oswald, Marion; Zandron, Claudio (Fénix Editora, 2004)
      We introduce a new variant of membrane systems where the rules are directly assigned to membranes (and not to the regions as this is usually observed in the area of membrane systems) and, moreover, every membrane carries ...

      Small Universal Antiport P Systems and Universal Multiset Grammars  [Presentation]

      Freund, Rudolf; Oswald, Marion (Fénix Editora, 2006)
      Based on the construction of a universal register machine we construct a universal antiport P system working with 31 rules in the maximally parallel mode in one membrane, and a universal antiport P system with forbidden ...
