    Wilmoth, Jared L.; Doak, Peter W.; Timm, Andrea; Halsted, Michelle; Anderson, John D.; Ginovart Gisbert, Marta; Prats Soler, Clara; Portell Canal, Xavier; Retterer, Scott T.; Fuentes-Cabrera, Miguel (2018-02-06)
    Article
    Open Access
    The factors leading to changes in the organization of microbial assemblages at fine spatial scales are not well characterized or understood. However, they are expected to guide the succession of community development and ...
  • Low Weber number jet collision regimes in microgravity 

    Suñol Galofre, Francesc Xavier; González Cinca, Ricardo (2017-11-01)
    Article
    Restricted access - publisher's policy
    The outcome of the collision between two liquid jets depends on the liquid properties, jet velocity, and impact angle. So far studies on liquid jet impingement have been carried out in normal gravity conditions. In ...
  • Mechanochemical pattern formation in simple models of active viscoelastic fluids and solids 

    Alonso Muñoz, Sergio; Radszuweit, Markus; Engel, Harald; Baer, Markus (Institute of Physics (IOP), 2017-11-01)
    Article
    Open Access
    The cytoskeleton of the organism Physarum polycephalum is a prominent example of a complex active viscoelastic material wherein stresses induce flows along the organism as a result of the action of molecular motors and ...
  • From genes to ecosystems in microbiology: modeling approaches and the importance of individuality 

    Kreft, Jan-Ulrich; Plugge, Caroline M.; Prats Soler, Clara; Leveau, Johan H. J.; Zhang, Weiwen; Hellweger, Ferdi L. (2017-11-27)
    Article
    Open Access
    Models are important tools in microbial ecology. They can be used to advance understanding by helping to interpret observations and test hypotheses, and to predict the effects of ecosystem management actions or a different ...
  • Modeling calcium dynamics in human atria 

    Rodríguez Cantalapiedra, Inma; Lugo Vélez, Carlos Antonio; Peñaranda Ayllón, Angelina; Hove-Madsen, Leif; Echebarría Domínguez, Blas (2014-01-02)
    Article

    Mathematical models of cardiac electrophysiology are an important tool to investigate the underlying mecha- nisms responsible of arrhythmias. In particular, an im- portant question is the origin of atrial fibrillation ...
  • Control of electrical turbulence by periodic excitation of cardiac tissue 

    Buran, Pavel; Bär, Markus; Alonso Muñoz, Sergio; Niedermayer, Thomas (Institute of Physics (IOP), 2017-11-01)
    Article
    Open Access
    Electrical turbulence in cardiac tissue is associated with arrhythmias such as life-threatening ventricular fibrillation. Recent experimental studies have shown that a sequence of low-energy electrical far-field pulses is ...
  • 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
    Open Access
    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
    Open Access
    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 ...
  • Nonlinear signaling on biological networks: The role of stochasticity and spectral clustering 

    Hernadez-Hernandez, Gonzalo; Myers, Jesse; Álvarez Lacalle, Enrique; Shiferaw, Yohannes (American Chemical Society (ACS), 2017-03-13)
    Article
    Open Access
    Signal transduction within biological cells is governed by networks of interacting proteins. Communication between these proteins is mediated by signaling molecules which bind to receptors and induce stochastic transitions ...
  • An experimental study of ultrasonic vibration and the penetration of granular material 

    Firstbrook, David; Worrall, Kevin; Timoney, Ryan; Suñol Galofre, Francesc Xavier; Gao, Yang; Harkness, Patrick (2017-02-01)
    Article
    Open Access
    This work investigates the potential use of direct ultrasonic vibration as an aid to penetration of granular material. Compared with non-ultrasonic penetration, required forces have been observed to reduce by an order of ...
  • Analysis of the characteristic lengths in the bubble and slug flow regimes generated in a capillary T-junction 

    Arias Calderón, Santiago; González Cinca, Ricardo (2016-09-20)
    Article
    Open Access
    We present an analysis of the geometry of the continuous and disperse phases in the bubble and slug flow regimes in air–water mixtures generated in a capillary T-junction of 1 mm internal diameter. Bubble size dispersion ...
