    • Vesicle motion during sustained exocytosis in chromaffin cells: numerical model based on amperometric measurements 

      Jarukanont, Daungruthai; Bonifas Arredondo, Imelda; Femat Flores, Alejandro Ricardo (2015)
      "Chromaffin cells release catecholamines by exocytosis, a process that includes vesicle docking, priming and fusion. Although all these steps have been intensively studied, some aspects of their mechanisms, particularly ...

    • A different three-port DC/DC converter for standalone PV system 

      Vázquez Nava, Nimrod; Sánchez, Carlos Manuel; Hernández Gutiérrez, Claudia Verónica; Vázquez Nava, Eslí; García, Luz del Carmen; Arau, Jaime (Hindawi, 2014)
      "A three-port converter suitable for standalone applications is proposed in this paper. Each port is used for specific input or output, and its functions depend on the port; they are the renewable source, the battery set, ...

    • Maximum power point tracking based on sliding mode control 

      Vázquez Nava, Nimrod; Azaf, Yuz; Cervantes Camacho, Ilse; Vázquez Nava, Eslí; Hernández Gutiérrez, Claudia Verónica (Hindawi, 2015)
      "Solar panels, which have become a good choice, are used to generate and supply electricity in commercial and residential applications. This generated power starts with the solar cells, which have a complex relationship ...

    • Stability of gain scheduling control for aircraft with highly nonlinear behavior
