Modeling domain formation of MARCKS and protein kinase C at cellular membranes
(EDP Sciences, 2014-01-30)
Article
Open AccessPhosphorylation and dephosphorylation of proteins are mechanisms of activation and deactivation which regulate many cellular processes. Both mechanisms have been usually described in well mixed environments. MARCKS is a ... -
Surfactant-induced gradients in the three-dimensional Belousov-Zhabotinsky reaction
(2011-11-10)
Article
Open AccessScroll waves are prominent patterns formed in three-dimensional excitable media, and they are frequently considered highly relevant for some types of cardiac arrhythmias. Experimentally, scroll wave dynamics is often studied ... -
Effects of reduced discrete coupling on filament tension in excitable media
(Institute of Physics (IOP), 2011-03-29)
Article
Open AccessWave propagation in the heart has a discrete nature, because it is mediated by discrete intercellular connections via gap junctions. Although effects of discreteness on wave propagation have been studied for planar traveling ... -
Experimental evidence of localized oscillations in the photosensitive chlorine dioxide-iodine-malonic acid reaction
(American Institute of Physics (AIP), 2006-10-24)
Article
Open AccessThe interaction between Hopf and Turing modes has been the subject of active research in recent years. We present here experimental evidence of the existence of mixed Turing-Hopf modes in a two-dimensional system. Using ... -
Intracellular mechanochemical waves in an active poroelastic model
(American Institute of Physics (AIP), 2013-04-25)
Article
Open AccessMany processes in living cells are controlled by biochemical substances regulating active stresses. The cytoplasm is an active material with both viscoelastic and liquid properties. We incorporate the active stress into a ... -
Twists of opposite handedness on a scroll wave
(American Institute of Physics (AIP), 2013-06-05)
Article
Open AccessThe dynamic interaction of scroll waves in the Belousov-Zhabotinsky reaction with a vertically orientated gradient of excitability is studied by optical tomography. This study focuses on scroll waves, whose filaments were ... -
Reentry near the percolation threshold in a heterogeneous discrete model for cardiac tissue
(American Institute of Physics (AIP), 2013-04-09)
Article
Open AccessArrhythmias in cardiac tissue are related to irregular electrical wave propagation in the heart. Cardiac tissue is formed by a discrete cell network, which is often heterogeneous. A localized region with a fraction of ... -
Negative filament tension at high excitability in a model of cardiac tissue
(American Institute of Physics (AIP), 2008-05-28)
Article
Open AccessOne of the fundamental mechanisms for the onset of turbulence in 3D excitable media is negative filament tension. Thus far, negative tension has always been obtained in media under low excitability. For this reason, its ... -
Negative filament tension in the Luo-Rudy model of cardiac tissue
(Institute of Physics (IOP), 2007-03-03)
Article
Open AccessScroll waves are vortices that occur in three-dimensional excitable media. Scroll waves have been observed in a variety of systems including cardiac tissue, where they are associated with cardiac arrhythmias. The disorganization ... -
Complex wave patterns in an effective reaction–diffusion model for chemical reactions in microemulsions
(American Institute of Physics (AIP), 2011-03-07)
Article
Open AccessAn effective medium theory is employed to derive a simple qualitative model of a pattern forming chemical reaction in a microemulsion. This spatially heterogeneous system is composed of water nanodroplets randomly distributed ... -
Effective medium approach for heterogeneous reaction-diffusion media
(American Institute of Physics (AIP), 2009-12-01)
Article
Open AccessAn effective medium theory that can be used to calculate effective diffusion and reaction rate coefficients in random heterogeneous reaction-diffusion systems is described. The predictions of the theory are compared with ... -
Development of canopy vigour maps using UAV for site-specific management during vineyard spraying process
(2019-01-01)
Article
Restricted access - publisher's policySite-specific management of crops represents an important improvement in terms of efficiency and efficacy of the different labours, and its implementation has experienced a large development in the last decades, especially ...
