Perturbation studies of excitable media
… Belousov-Zhabotinsky (BZ) reaction. One is self-organized criticality and the other is periodic forcing and how they can be studied with the BZ reaction. Self-organized criticality is the ability of a system to organize itself into a critical state as a response to random perturbations. …

Spatial competition and nonlinear responses in marketing
… and robust stochastic steady state known as self-organized criticality (SOC). One characteristic of the SOC state is that it allows small exogenous shocks to produce large responses at a rate greater than would be expected if the law of large numbers applied. This work represents the first …

Shared memory parallelization for large scale 3D polyhedral particle simulations
… simulations demonstrated the ability to capture self-organized criticality related to natural complex system by showing the distribution of sliding mass that followed a power law relationship. The parallelized particle-based simulation extends the limits of application size by reducing …

Interfacial Fluid Dynamics in Porous Media
… Finally, we explore intriguing features of self-organized criticality during fluid-fluid displacement in disordered porous media. In Part II, we examine fluid displacement at a scale of a single capillary. We use lubrication theory to produce precise predictions of film evolution during …

Criticality control of insulin release: a novel alternative for detailed modelling of insulin secretion
… of a set of sixteen coupled oscillators organized into four clusters. It successfully incorporates characteristics that have been observed in the glucose-insulin system, such as nonlinear dynamics, coupling, and response to external influences. In order to tune the system and achieve …

A new triggering mechanism of the boiling crisis based on the percolation theory and its implication
… Inspired by the concurrence of scale-free criticality and complexity in many of the aforementioned physical systems, we analyze the fractal behavior of the bubble interaction process and show that the critical phase transition in this phenomenon (i.e., the boiling crisis), coincides with a …

Autonomous Experimentation to Accelerate Boiling Heat Transfer Research
… were utilized to demonstrate the presence of self-organized criticality (SOC) in nucleate boiling. SOC was observed to emerge from bubble interactions near the wall and was characterized by nucleation site density, average bubble footprint radius, and the product of average bubble growth time …

Self-organization in continuous adaptive networks
Komplexe Systeme können oftmals durch adaptive Netzwerke beschrieben werden. Diese zeichnen sich dadurch aus, dass lokale und topologische Freiheitsgrade dynamisch gekoppelt sind, was zu einer Fülle von Selbstorganisationsphänomenen führt. Analytische Studien können zum Verständnis der Mechanismen …

Física y fisicoquímica de espumas líquidas : espumas inteligentes
… que exhiben criticalidad auto- organizada (Self-organized Criticality, SOC). Por otro lado, hemos logrado formular espumas inteligentes cuya estabilidad puede ser modulada, de forma reversible, por cambios de temperatura y pH. Estos sistemas están basados en complejos mezcla de …

Complexity in physical, living and mathematical systems
… on a simple algorithm whose dynamics evidence Self-Organized Criticality (SOC). We prove that this dynamical behavior is directly related to the underlying network of interactions of the system. Specifically, we find that that the underlying network's scale free topology induces criticality in …

Avalanche dynamics of structural phase transitions in shape memory alloys by acoustic emission spectroscopy
… reveals a close relation to the concept of self organized criticality. In this work it has been shown for the first time by the evaluation of power law exponents how an applied magnetic field alters energy barriers during structural transitions of magnetic shape memory alloys. Depending on …
