  • 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 ...
  • Ectopic beats arise from micro-reentries near infarct regions in simulations of a patient-specific heart model 

    sachetto Oliveira, Rafael; Alonso Muñoz, Sergio; Otaviano Campos, Fernando; Martins Rocha, Bernardo; Filipe Fernandes, João; Kuehne, Titus; Weber dos Santos, Rodrigo (Nature, 2018-12-01)
    Article
    Open Access
    Ectopic beats are known to be involved in the initiation of a variety of cardiac arrhythmias. Although their location may vary, ectopic excitations have been found to originate from infarct areas, regions of micro-fibrosis ...
  • Histidine decarboxylase-positive lactic acid bacteria strains and the formation of histamine in ripened cheeses 

    Valle Mendoza, Luis Javier del; Ginovart Gisbert, Marta; Gordún Quiles, Elena; Carbó Moliner, Rosa (2018-09-14)
    Article
    Open Access
    The relationship between histidine decarboxylase-positive (hdc+) lactic acid bacteria (LAB) counts and the amounts of biogenic amines, particularly histamine, in cheeses made with and without LAB starter were investigated. ...
  • Killing many birds with two stones: hypoxia and fibrosis can generate ectopic beats in a human ventricular model 

    sachetto Oliveira, Rafael; Alonso Muñoz, Sergio; Weber dos Santos, Rodrigo (2018-06-22)
    Article
    Open Access
    During cardiac diseases many types of anatomical and functional remodeling of cardiac tissue can occur. In this work, we focus on two conditions: hypoxia and fibrosis, which are part of complex pathological modifications ...
  • Development of a computational model of abscess formation 

    Pigozzo, Alexandre B.; Missiakas, Dominique; Alonso Muñoz, Sergio; Weber dos Santos, Rodrigo; Lobosco, Marcelo (2018-06-26)
    Article
    Open Access
    In some bacterial infections, the immune system cannot eliminate the invading pathogen. In these cases, the invading pathogen is successful in establishing a favorable environment to survive and persist in the host organism. ...
