  • Spatial Filters on Demand Based on Aperiodic Photonic Crystals 

    Gailevicius, Darius; Purlys, Vytautas; Peckus, Martynas; Gadonas, Roaldas; Staliunas, Kestutis (2017-08-01)
    Article
    Accés restringit per política de l'editorial
    Photonic Crystal spatial filters, apart from stand-alone spatial filtering function, can also suppress multi-transverse-mode operation in laser resonators. Here it is shown that such photonic crystals can be designed by ...
  • Self-organized kilometer-scale shoreline sand wave generation: sensitivity to model and physical parameters 

    Idier, Déborah; Falqués Serra, Albert; Rohmer, Jérémy; Arriaga García, Jaime Alonso (2017-09-19)
    Article
    Accés obert
    The instability mechanisms for self-organized kilometer-scale shoreline sand waves have been extensively explored by modeling. However, while the assumed bathymetric perturbation associated with the sand wave controls the ...
  • An indium tin oxide-free polymer solar cell on flexible glass 

    Formica, Nadia; Mantilla Perez, Paola; Ghosh, Dhriti Sundar; Janner, Davide; Chen, T. L.; Huang, Minghuang; Garner, Sean; Martorell Pena, Jordi; Pruneri, Valerio (2015-02-05)
    Article
    Accés obert
    Future optoelectronic devices and their low-cost roll-to-roll production require mechanically flexible transparent electrodes (TEs) and substrate materials. Indium tin oxide (ITO) is the most widely used TE because of its ...
  • Monitoring degradation mechanisms in PTB7:PC71BM photovoltaic cells by means of impedance spectroscopy 

    Arredondo, Belen; Martin Lopez, Maria B.; Romero, Beatriz; Vergaz, Ricardo; Romero Gómez, Pablo; Martorell Pena, Jordi (2015-10-23)
    Article
    Accés restringit per política de l'editorial
    We have used impedance spectroscopy technique to monitor degradation mechanisms in organic solar cells based on a blend of PTB7:PC71BM. We have measured the impedance of the cell on a periodical basis for almost four months, ...
  • Slow ß relaxation in La-based metallic glasses based on mechanical spectroscopy measurements 

    Qiao, Jichao; Pelletier, J. M.; Li, Ning; Crespo Artiaga, Daniel; Yao, Yao (2017-04-01)
    Article
    Accés restringit per política de l'editorial
    Dynamic mechanical relaxations of La-based metallic glasses were investigated by mechanical spectroscopy. In the framework of the mixing enthalpy of constituent atoms, it was found that ß relaxation was less evident by the ...
  • Updated evolutionary sequences for hydrogen-deficient white dwarfs 

    Camisassa, Maria E; Althaus, Leandro G.; Rohrmann, René D.; García-Berro Montilla, Enrique; Torres Gil, Santiago; Corsico, Alejandro H.; Wachlin, Felipe C. (Institute of Physics (IOP), 2017-04-10)
    Article
    Accés obert
    We present a set of full evolutionary sequences for white dwarfs with hydrogen-deficient atmospheres. We take into account the evolutionary history of the progenitor stars, all the relevant energy sources involved in the ...
  • Minimal model for calcium alternans due to SR release refractoriness 

    Rodríguez Cantalapiedra, Inma; Álvarez Lacalle, Enrique; Peñaranda Ayllón, Angelina; Echebarría Domínguez, Blas (Institute of Physics (IOP), 2017-09-07)
    Article
    Accés obert
    In the heart, rapid pacing rates may induce alternations in the strength of cardiac contraction, termed pulsus alternans. Often, this is due to an instability in the dynamics of the intracellular calcium concentration, ...
  • The malaria system microApp: A new, mobile device-based tool for malaria diagnosis 

    Oliveira, Alisson Dantas; Prats Soler, Clara; Espasa, Mateu; Zarzuela, Francesc; Montañola Sales, Cristina; Silgado, Aroa; López Codina, Daniel; Arruda, Mercia Eliane; Gómez, Jordi; Albuquerque, Jones O. (2017-04-25)
    Article
    Accés obert
    Background: Malaria is a public health problem that affects remote areas worldwide. Climate change has contributed to the problem by allowing for the survival of Anopheles in previously uninhabited areas. As such, several ...
  • Modeling the long-term diffusion and feeding capability of a mega-nourishment 

    Arriaga García, Jaime Alonso; Rutten, Jantien; Ribas Prats, Francesca; Falqués Serra, Albert; Ruessink, Gerben (2017-03-01)
    Article
    Accés restringit per política de l'editorial
    A morphodynamic model based on the wave-driven alongshore sediment transport, including cross-shore transport in a simplified way and neglecting tides, is presented and applied to the Zandniotor mega-nourishment on the ...
  • Lepton flavor changing Higgs decays in the littlest Higgs model with T-parity 

    del Aguila Jiménez, Francisco; Ametller Congost, Lluís; Illana, José Ignacio; Santiago, Jose; Talavera, Pere; Vega-Morales, Roberto (2017-08-08)
    Article
    Accés obert
    We calculate loop induced lepton flavor violating Higgs decays in the Littlest Higgs model with T-parity. We find that a finite amplitude is obtained only when all contributions from the T-odd lepton sector are included. ...
