      Background: Gene co-expression evidenced as a response to environmental changes has shown that transcriptional activity is coordinated, which pinpoints the role of transcriptional regulatory networks (TRNs). Nevertheless, ...
    • Cabezas, Christopher; Donoso, Sebastián; Maass Sepúlveda, Alejandro (Cambridge University Press, 2020)
      We introduce the notions of directional dynamical cubes and directional regionally proximal relation defined via these cubes for a minimal Z(d)-system. X; T-1, ...,T-d). We study the structural properties of systems that ...
    • Durand, Fabien; Frank, Alexander; Maass Sepúlveda, Alejandro (European Mathematical Society Publishing House, 2019)
