  • Unstable state decay in non-Markovian heat baths and weak signals detection 

    Jiménez Aquino, José Inés; Sánchez Salas, Norma; Ramírez de la Piscina Millán, Laureano; Romero Bastida, M. (2019-09-01)
    Article
    Open Access
    The statistics of the first passage and nonlinear relaxation times are used to characterize the decay process of an unstable state for an electrically charged Brownian particle embedded in non-Markovian heat baths under ...
  • Identification of yeast isolated from laboratory sourdoughs prepared with grape, apple, and yogurt

  • Effects of gravity level on bubble detachment, rise, and bouncing with a free surface 

    Suñol Galofre, Francesc Xavier; González Cinca, Ricardo (2019-02-05)
    Article
    Open Access
    Bubble detachment, rise, and bouncing upon impact with a free surface is studied experimentally in variable gravity conditions. Previous investigations focused on the effects of fluid properties such as ...
  • Stochastic coupled map model of subcellular calcium cycling in cardiac cells 

    Romero Castañeda, Luis; Álvarez Lacalle, Enrique; Shiferaw, Yohannes (Institute of Physics (IOP), 2019-02-01)
    Article
    Restricted access - publisher's policy
    In this study, we analyze a nonlinear map model of intracellular calcium (Ca) and voltage in cardiac cells. In this model, Ca release from the sarcoplasmic reticulum (SR) occurs at spatially distributed dyadic junctions ...
  • Stability of oscillating hexagons in rotating convection 

    Echebarría Domínguez, Blas; Riecke, Hermann (2000)
    Article
    Open Access
    Breaking the chiral symmetry, rotation induces a secondary Hopf bifurcation in weakly nonlinear hexagon patterns which gives rise to oscillating hexagons. We study the stability of the oscillating hexagons using three ...
  • Sideband instabilities and defects of quasipatterns 

    Echebarría Domínguez, Blas; Riecke, Hermann (2001)
    Article
    Open Access
    Quasipatterns have been found in dissipative systems ranging from Faraday waves in vertically vibrated fluid layers to nonlinear optics. We describe the dynamics of octagonal, decagonal and dodecagonal quasipatterns by ...
  • Spatiotemporal control of cardiac alternans 

    Echebarría Domínguez, Blas; Karma, Alain (Institute of Physics (IOP), 2002)
    Article
    Restricted access - publisher's policy
    Electrical alternans are believed to be linked to the onset of life-threatening ventricular arrhythmias and sudden cardiac death. Recent studies have shown that alternans can be suppressed temporally by dynamic feedback ...
  • Computational Model of Calcium Signaling in Cardiac Atrial Cells at the Submicron Scale 

    Marchena Angos, Miquel; Echebarría Domínguez, Blas (2018-12-10)
    Article
    Open Access
    In cardiac cells, calcium is the mediator of excitation-contraction coupling. Dysfunctions in calcium handling have been identified as the origin of some cardiac arrhythmias. In the particular case of atrial myocytes, ...
  • Analyzing policymaking for tuberculosis control in Nigeria 

    Ahmad, Nura MR; Montañola Sales, Cristina; Prats Soler, Clara; Musa, Mustapha; López Codina, Daniel; Casanovas Garcia, Josep (2018-11-07)
    Article
    Open Access
    Today, tuberculosis (TB) is still one of the major threats to humankind, being the first cause of death by an infectious disease worldwide. TB is a communicable chronic disease that every year affects 10 million people ...
  • Congenital and blood transfusion transmission of chagas disease: A framework using mathematical modeling 

    Ramalho, Edneide; Albuquerque, Jones O.; Cristino, Cláudio; Lorena, Virginia; Gómez i Prat, Jordi; Prats Soler, Clara; López Codina, Daniel (2018-11-01)
    Article
    Open Access
    Chagas disease or American trypanosomiasis is an important health problem in Latin America. Due to the mobility of Latin American population around the world, countries without vector presence started to report disease ...
  • A sounding rocket experiment to control boiling by means of acoustic waves 

    Quintana Buil, Guillem; Garcia Sabaté, Anna; Batlle, Sergi; López, Gabriel; Sierra, Víctor; Casas, O.; González Cinca, Ricardo (2018-01-01)
    Article
    Open Access
    One of the most critical issues when considering long-term space exploration missions is the management and storage of cryogenic propellants. The exposure of storage tanks to radiation and extreme temperatures implies the ...
  • Can systems immunology lead tuberculosis eradication? 

    Cardona Iglesias, Pere Joan; Català, Martí; Arch, Marta; Arias, Lilibeth; Alonso Muñoz, Sergio; Cardona, Paula; López Codina, Daniel; Vilaplana, Cristina; Prats Soler, Clara (Elsevier, 2018-10-30)
    Article
    Open Access
    25 years after the declaration of a Global Emergency by the World Health Organization, tuberculosis (TB) remains a major enemy to the humankind. During this period, much progress has been done to better understand its ...
