Distance Dependence of Electron-Transfer Reactions in Organized Systems:The Role of Superexchange and Non-Condon Effects in Photosynthetic Reaction Centers
Distance Dependence Electron-Transfer Reactions Organized Systems Superexchange Non-Condon Photosynthetic Reaction Centers
2016/5/23
Extremely long distance electron transfer is observed in some photosynthetic reaction centers. For several charge recombination reactions, the rate appears to fall off much more slowly with distance t...
Neuronal avalanches of a self-organized neural network with active-neuron-dominant structure
Neuronal avalanches self-organized neural network active-neuron-dominant structure Neurons and Cognition
2012/5/3
Neuronal avalanche is a spontaneous neuronal activity which obeys a power-law distribution of population event sizes with an exponent of -3/2. It has been observed in the superficial layers of cortex ...
Can Self Organized Critical Accretion Disks Generate a Log-normal Emission Variability in AGN?
Accretion accretion disks
2011/9/29
Active Galactic Nuclei (AGN), such as Seyfert galaxies, quasars, etc., show light variations in all wavelength bands, with various amplitude and in many time scales. The variations usually look errati...
Corporate competition: A self-organized network
Corporate competition self-organized network Adaptation and Self-Organizing Systems
2011/8/2
Abstract: A substantial number of studies have extended the work on universal properties in physical systems to complex networks in social, biological, and technological systems. In this paper, we pre...
An Agent-Based Approach to Self-Organized Production
Agent-Based Approach Self-Organized Production
2010/12/28
The chapter describes the modeling of a material handling system with the production of individual units in a scheduled order. The units represent the agents in the model and are transported in the sy...
Replicating financial market dynamics with a simple self-organized critical lattice model
Computational Finance (q-fin.CP) Adaptation and Self-Organizing Systems (nlin.AO)
2010/11/11
We explore a simple lattice field model intended to describe statistical properties of high frequency financial markets. The model is relevant in the cross-disciplinary area of econophysics. Its signa...
Self-organized criticality as a precursor of fatigue: application to shape memory alloys
Adaptation and Self-Organizing Systems (nlin.AO)
2010/11/10
Fatigue failure can be thought by studying the collective motions of defects inside materials instead of focusing on the growth of a pre-existing micro-crack. An experimental study of the statistical ...
Universal fractal scaling of self-organized networks
Universal fractal scaling self-organized networks
2010/11/10
There is an abundance of literature on complex networks describing a variety of relationships among units in social, biological, and technological systems. Such networks, consisting of interconnected ...
Emergence of cooperation with self-organized criticality
self-organized criticality Physics
2010/11/16
Cooperation and self-organized criticality are two main keywords in current studies of evolution. We propose a generalized Bak-Sneppen model and provide a natural mechanism which accounts for both ph...
Self-Organized Criticality in Proteins: Hydropathic Roughening Profiles of G-Protein Coupled Receptors
Proteins: Hydropathic Roughening Profiles G-Protein Coupled Receptors
2010/11/24
Proteins appear to be the most dramatic natural example of self-organized criticality (SOC), a concept that explains many otherwise apparently unlikely phenomena. Protein conformational functionality ...
The State of Self-Organized Criticality of the Sun During the Last Three Solar Cycles. II. Theoretical Model
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
The observed powerlaw distributions of solar flare parameters can be interpreted in terms of a nonlinear dissipative system in the state of self-organized criticality (SOC).
Landslides, sandpiles, and self-organized criticality
Landslides sandpiles self-organized criticality
2009/12/10
Power-law distributions of landslides and rockfalls observed under various conditions suggest a relationship of mass movements to self-organized criticality (SOC). The exponents of the distributions s...
Mulifractal phase transitions:the origin of self-organized criticality in earthquakes
Mulifractal phase transitions self-organized criticality in earthquakes
2009/11/16
Fractal and occasionally multifractal behaviour has been invoked to characterize (independently of their magnitude) the spatial distribution of seismic epicenters, whereas more recently, the frequency...
Faults self-organized by repeated earthquakes in a quasi-static antiplane crack model
Faults self-organized by repeated earthquakes quasi-static antiplane crack model
2009/11/13
We study a 2D quasi-static discrete crack anti-plane model of a tectonic plate with long range elastic forces and quenched disorder. The plate is driven at its border and the load is transferred to al...
Size-frequency distribution of earthquakes in hierarchically organized load-transfer models
Size-frequency distribution of earthquakes hierarchically organized load-transfer models
2009/11/13
Large hierarchically organized sets of elements (simulating asperities in a fault) are loaded to the point of complete failure. The fracture thresholds of individual elements are stochastically distri...
