    Studies involving Monte Carlo simulations are common in both diagnostic and therapy medical phy- sics research, as well as other fields of basic and applied science. As with all experimental studies , the conditions and ...

  • Influence of extrinsic contribution on the macroscopic properties of hard and soft lead zirconate titanate ceramics 

    Ochoa Guerrero, Diego A.; García García, José Eduardo; Pérez Pérez, Rafael; Albareda Tiana, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2008-12)
    Article
    Accés obert
    In this work, the contribution of the extrinsic effect to the macroscopic properties in soft and hard lead zirconate titanate ceramics is directly evaluated. Close to the room temperature, poled hard ceramics show an ...

  • Nonlinear behavior in a piezoelectric resonator: a method of analysis 

    García García, José Eduardo; Pérez Pérez, Rafael; Albareda Tiana, Alfonso; Minguella Blasco, Enric (Institute of Electrical and Electronics Engineers (IEEE), 2000-07)
    Article
    Accés obert
    Theories used for understanding nonlinear behavior of piezoelectric resonators are usually only valid for a given range of amplitudes. Thus, important discrepancies can sometimes be observed between theory and experiment. ...

  • Unexpected dielectric response in lead zirconate titanate ceramics: The role of ferroelectric domain wall pinning effects 

    García García, José Eduardo; Gomis Arbonès, Vicente; Pérez Pérez, Rafael; Albareda Tiana, Alfonso; Eiras, Jose A. (2007-07)
    Article
    Accés obert
    Temperature dependent dielectric response has been measured in Pb(Zr1-xTix)O-3 ceramics. Samples of different compositions (x=0.40, 0.47, and 0.60), pure and doped with Nb-or Fe, were studied at temperatures between 15 and ...

  • Optimization of elastic nonlinear behavior measurements of ceramic piezoelectric resonators with burst excitation

    A system of nonlinear measurement and nonlinear elastic characterization of resonators is presented, which increases the possibilities and characteristics of the other classic nonlinear characterization methods. This ...

  • Modeling random crawling, membrane deformation and intracellular polarity of motile amoeboid cells 

    Alonso Muñoz, Sergio; Stange, Maike; Beta, Carsten (Public Library of Science (PLOS), 2018-08-01)
    Article
    Accés obert
    Amoeboid movement is one of the most widespread forms of cell motility that plays a key role in numerous biological contexts. While many aspects of this process are well investigated, the large cell-to-cell variability ...

  • Reevaluation of radiation reaction and consequences for light-matter interactions at the nanoscale 

    Escalora, M.; Vinceti, Maria Antonietta; Ceglia, Domenico de; Trullàs Simó, Joaquim; Cojocaru, Crina (2018-06-27)
    Article
    Accés obert
    In the context of electromagnetism and nonlinear optical interactions, damping is generally introduced as a phenomenological, viscous term that dissipates energy, proportional to the temporal derivative of the polarization. ...
