      A Biological Perspective on Sorting with P Systems  [Presentation]

      Ardelean, Ioan I.; Ceterchi, Rodica; Tomescu, Alexandru Ioan (Fénix Editora, 2008)
      The aim of this contribution is to argue that the processes occurring in biological membranes in bacteria are also important as natural examples of communication between membranes, which, in the formal framework of P ...

      Communication and Stochastic Processes in Some Bacterial Populations: Significance for Membrane Computing  [Presentation]

      Ardelean, Ioan I. (Fénix Editora, 2009)
      Intercellular communication between bacterial cells belonging to the same population is well documented in Microbiology, sporulation and cannibalism in B. Subtilis and genetic competence and fratricide in S. pneumoniae ...

      Computing Using Signals: From Cells to P Systems  [Presentation]

      Ardelean, Ioan I.; Cavaliere, Matteo; Sburlan, Dragos (Fénix Editora, 2004)
      In cell biology one of the fundamental topic is the study of how biological signals are managed by cells. Signals can arise from inside the cell or from the external environment and the correct answer to certain signals ...

      Counting Cells with Tissue-like P Systems  [Presentation]

      Ardelean, Ioan I.; Díaz Pernil, Daniel; Gutiérrez Naranjo, Miguel Ángel; Peña Cantillana, Francisco; Reina Molina, Raúl; Sarchizian, Iris (Fénix Editora, 2012)
      Counting the number of cells obtained in an experiment is crucial in many areas in Biology. Nonetheless, this is usually performed by hand by the researcher due the intrinsic difficulty of the task. In this paper, we ...

      Magnetotactic Bacteria and Their Significance for P Systems and Nanoactuators  [Presentation]

      Ardelean, Ioan I.; Ignat, Mircea; Moisescu, Cristina (Fénix Editora, 2007)
      In the framework of the dialog between P systems and Microbiology, in this paper we focus on the magnetotactic behavior of magnetotactic bacteria, namely the orientation along the Earth’s geomagnetic field lines. Magnetic ...

      Membrane Proteins as Maxwell’s Demons and Their Significance for P Systems  [Presentation]

      Ardelean, Ioan I.; Moisescu, Cristina; Lazaroaie, Mihaela Marilena (Fénix Editora, 2008)
      The aim of these notes is to contribute to the dialog between P systems and Biological Sciences focussing on membrane proteins involved either in iron transport inside the bacterial cells or in elimination outside the ...

      New Proposals for the Formalization of Membrane Proteins  [Presentation]

      Ardelean, Ioan I.; Besozzi, Daniela (Fénix Editora, 2004)
      This paper presents three new proposals to take advantage, in the framework of P systems, from proteins acting in bacteria. One attempt aims to focus on the transport protein that act as a logic AND gate at the cell membrane. ...

      On Modelling Ion Fluxes Across Biological Membranes with P Systems  [Presentation]

      Ardelean, Ioan I.; Besozzi, Daniela (Fénix Editora, 2005)
      In this report we address the challenge of using P systems to integrate at the whole cell level both active and passive transport of different ions, done by different types of membrane transport proteins which work ...

      Some Notes on the Interplay Between P Systems and Chemotaxis in Bacteria  [Presentation]

      Ardelean, Ioan I.; Besozzi, Daniela (Fénix Editora, 2006)
      We describe some chemotactic behaviors of bacteria, that is, their movement response to changes in the environment, and the underlying molecular mechanisms. We outline how such processes could be linked to membrane ...

      Studying the Chlorophyll Fluorescence in Cyanobacteria with Membrane Computing Techniques  [Presentation]

      Ardelean, Ioan I.; Díaz Pernil, Daniel; Gutiérrez Naranjo, Miguel Ángel; Peña Cantillana, Francisco; Sarchizian, Iris (Fénix Editora, 2013)
      In this paper, we report a pioneer study of the decrease in chlorophyll uorescence produced by the reduction of MTT (a dimethyl thiazolyl diphenyl tetrazolium salt) monitored using an epi uorescence microscope coupled ...
