    • Reeb’s theorem and periodic orbits for a rotating Hénon–Heiles potential 

      Lanchares, Víctor; Pascual, Ana Isabel; Iñarrea, Manuel; Salas, José Pablo; Palacián Subiela, Jesús Francisco Upna; Yanguas Sayas, Patricia Upna (Springer, 2019)   Artículo / Artikulua  OpenAccess
      We apply Reeb’s theorem to prove the existence of periodic orbits in the rotating Hénon– Heiles system. To this end, a sort of detuned normal form is calculated that yields a reduced system with at most four non degenerate ...
    • Sliding window averaging in normal and pathological motor unit action potential trains 

      Malanda Trigueros, Armando Upna; Navallas Irujo, Javier Upna; Rodríguez Falces, Javier Upna; Porta Cuéllar, Sonia Upna; Fernández Martínez, Miguel (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      Objective: To evaluate the performance of a recently proposed motor unit action potential (MUAP) averaging method based on a sliding window, and compare it with relevant published methods in normal and pathological muscles. ...
