    • IconComputing with Spiking Neural P Systems: Traces and Small Universal Systems  [Chapter of Book]

      Ionescu, Mihai; Paun, Andrei; Paun, Gheorghe; Pérez Jiménez, Mario de Jesús (Springer, 2006)
      Recently, the idea of spiking neurons and thus of computing by spiking was incorporated into membrane computing, and so-called spiking neural P systems (abbreviated SN P systems) were introduced. Very shortly, in these ...
    • IconFurther Remarks on Trace Languages in P Systems with Symport/Antiport  [Presentation]

      Liu, Guangwu; Ionescu, Mihai (Fénix Editora, 2006)
      P systems are parallel molecular computing models which process multisets of objects in cell-like membrane structures. In this paper we consider the trace languages of a special symbol, the traveler, in symport/antiport ...
    • IconNotes About Spiking Neural P Systems  [Presentation]

      Ionescu, Mihai; Paun, Gheorghe (Fénix Editora, 2011)
      Spiking neural P systems (SN P systems, for short) are much investigated in the last years in membrane computing, but still many open problems and research topics are open in this area. Here, we first recall two such ...
    • IconOn P Systems with Promoters/Inhibitors  [Presentation]

      Ionescu, Mihai; Sburlan, Dragos (Fénix Editora, 2004)
      This article shows how the computational universality can be reached by using P systems with object rewriting context-free rules, promot- ers/inhibitors and one catalyst. Both generative and accepting cases are stud- ied. ...
    • IconOn String Languages Generated by Spiking Neural P Systems  [Presentation]

      Chen, Haiming; Freund, Rudolf; Ionescu, Mihai; Paun, Gheorghe; Pérez Jiménez, Mario de Jesús (Fénix Editora, 2006)
      We continue the study of spiking neural P systems by considering these computing devices as binary string generators: the set of spike trains of halting computations of a given system constitutes the language generated ...
    • IconOn the Efficiency of Spiking Neural P Systems  [Presentation]

      Chen, Haiming; Ionescu, Mihai; Ishdorj, Tseren-Onolt (2006)
      Spiking neural P systems were recently introduced in and proved to be Turing complete as number computing devices. In this paper we show that these systems are also computationally efficient. Specifically, we present a ...
    • IconOn Trace Languages Generated by Spiking Neural P Systems  [Presentation]

      Chen, Haiming; Ionescu, Mihai; Paun, Andrei; Paun, Gheorghe; Popa, Bianca (Fénix Editora, 2006)
      We extend to spiking neural P systems a notion investigated in the “stan- dard” membrane systems: the language of the traces of a distinguished object. In our case, we distinguish a spike by “marking” it and we follow ...
    • IconP Systems with Adjoining Controlled Communication Rules  [Presentation]

      Ionescu, Mihai; Sburlan, Dragos (Fénix Editora, 2007)
      This paper proposes a new model of P systems where the rules are activated by objects present in the neighboring regions. We obtain the computational completeness considering only two membranes, external inhibitors and ...
    • IconSeveral Applications of Spiking Neural P Systems  [Presentation]

      Ionescu, Mihai; Sburlan, Dragos (Fénix Editora, 2007)
      In this paper we investigate some applications of Spiking Neural P Systems regarding their capability to solve some classical computer science problems. In this respect it is studied the versatility of such systems to ...
    • IconSpiking Neural dP Systems  [Presentation]

      Ionescu, Mihai; Paun, Gheorghe; Pérez Jiménez, Mario de Jesús; Yokomori, Takashi (Fénix Editora, 2011)
      We bring together two topics recently introduced in membrane computing, the much investigated spiking neural P systems (in short, SN P systems), inspired from the way the neurons communicate through spikes, and the dP ...
    • IconSpiking neural P systems with extended rules: universality and languages  [Article]

      Chen, Haiming; Ionescu, Mihai; Ishdorj, Tseren-Onolt; Paun, Andrei; Paun, Gheorghe; Pérez Jiménez, Mario de Jesús (Springer, 2008)
      We consider spiking neural P systems with rules allowed to introduce zero, one, or more spikes at the same time. The motivation comes both from constructing small universal systems and from generating strings; previous ...
    • IconSpiking Neural P systems with several types of spikes  [Article]

      Ionescu, Mihai; Paun, Gheorghe; Pérez Jiménez, Mario de Jesús; Rodríguez Patón, Alfonso (Agora University of Oradea, 2011)
      With a motivation related to gene expression, where enzymes act in series, somewhat similar to the train spikes traveling along the axons of neurons, we consider an extension of spiking neural P systems, where several ...
