      Approximate Best Proximity Points of Cyclic Self-maps in Metric Spaces and Cyclic Asymptotic Regularity 

      De la Sen Parte, Manuel ORCID (IOP Publishing, 2015)
      This manuscript investigates some relations and properties between 2-cyclic self-mappings. In particular, a formal development is given to link some concepts and their basic related properties like those of approximate ...

      Defects structure characterization of NiMnGa alloys by PALS 

      Mérida Sanz, David; García Martínez, José Angel; Plazaola Muguruza, Fernando ORCID; Sánchez Alarcos, Vicente; Pérez Landazbal, Jose Ignacio; Recarte, Vicente (IOP Publishing, 2013)
      We have studied the behaviour of defects in off-stoichiometric Ni-Mn-Ga ferromagnetic shape memory alloys by means of positron lifetime spectroscopy. The measurements presented in this work have been performed in six ternary ...

      Is General Relativity a simplified theory? 

      Rivas Pérez, Martín (IOP Publishing, 2013)
      Gravity is understood as a geometrization of spacetime. But spacetime is also the manifold of the boundary values of the spinless point particle in a variational approach. Since all known matter, baryons, leptons and gauge ...
