Power Law versus Exponential State Transition Dynamics: Application to Sleep-Wake Architecture
BACKGROUND Despite the common experience that interrupted sleep has a negative impact on waking function, the features of human sleep-wake architecture that best distinguish sleep continuity versus fragmentation remain elusive. In this regard, there is growing interest in characterizing sleep architecture using models of the temporal dynamics of sleep-wake stage transitions. In humans and other...
متن کاملPower-law versus exponential distributions of animal group sizes.
There has been some confusion concerning the animal group size: an exponential distribution was deduced by maximizing the entropy; lognormal distributions were practically used; as power-law decay with exponent 3/2 was proposed in physical analogy to aerosol condensation. Here I show that the animal group-size distribution follows a power-law decay with exponent 1, and is truncated at a cut-off...
متن کاملTransition from Exponential to Power Law Income Distributions in a Chaotic Market
Economy is demanding new models, able to understand and predict the evolution of markets. To this respect, Econophysics offers models of markets as complex systems, that try to comprehend macro-, system-wide states of the economy from the interaction of many agents at micro-level. One of these models is the gas-like model for trading markets. This tries to predict money distributions in closed ...
متن کاملEffects of Sleep-Wake State on the Genioglossus Versus Diaphragm Muscle Responses to CO2 in Rats
The effects of sleep on the ventilatory responses to hypercapnia have been well described in animals and humans. In contrast, there is little information for genioglossus (GG) responses to a range of CO2 stimuli across all sleep-wake states. Given the notion that sleep, especially rapid-eye-movement (REM) sleep, may cause greater suppression of muscles with both respiratory and non-respiratory ...
متن کاملSlow synaptic dynamics in a network: from exponential to power-law forgetting.
We investigate a mean-field model of interacting synapses on a directed neural network. Our interest lies in the slow adaptive dynamics of synapses, which are driven by the fast dynamics of the neurons they connect. Cooperation is modeled from the usual Hebbian perspective, while competition is modeled by an original polarity-driven rule. The emergence of a critical manifold culminating in a tr...
