Due to these characteristics, self-organized criticality is intuitively attractive as a model for brain functions such as perception and action, because it would allow us to switch quickly between mental states in order to respond to changing environmental conditions," said co-author Manfred Kitzbichler.
Shepherding his authence through a thicket of terminology such as nonbolametric photon absorption, diamagnetic properties, and self-organized criticality, Sines explained that in a "solar vortex cylinder" - a glass or ceramic tube overlaid by a thin superconductive alloy film, cooled by liquid nitrogen, and coupled to a permanent magnet - impinging sunlight causes "photon modulation of magnetic flux" that generates a voltage.
It would seem that a complexity theory formalism can accurately describe both ambiguity and vagueness: Language can be construed as a self-organizing network, replete with self-organized criticality.
Bak uses the universality of these properties to argue that some general, underlying theory must be applicable to all the systems that display them: Self-organized criticality as seen in a sandpile must also be responsible for earthquakes, solar flares, river branching structures, urban population distributions, biological extinction waves, macroeconomic fluctuations, and a whole lot more.
Physicists have explored the possibility that self-organized criticality occurs when sand grains are added to sandpiles, creating avalanches ranging in size from just a few grains to entire slopes (SN: 7/15/89, p.
Power laws, regime shifts, self-organized criticality, phase transitions, network dynamics, econophysics, algorithmic trading and other ideas from the science of complexity are examined.
