بررسی تحریک جمعی نورون ها تحت اثر نوفه در حالت برانگیخته در شبکه های جهان کوچک و تصادفی
Synchrony is significant in brain neural network. In this study we investigate the collective firing in an excitable media and modeling the brain network by an small-world one. The Gaussian white noise is taken to the system of phase oscillators, and then to the frequency distribution. An order parameter in non stationary situation and other usefull statistical parameters such as firing are co...
متن کاملDerivation of the probability distribution function for the local density of states of a disordered quantum wire via the replica trick and supersymmetry
We consider the statistical properties of the local density of states of a one-dimensional Dirac equation in the presence of various types of disorder with Gaussian white-noise distribution. It is shown how either the replica trick or supersymmetry can be used to calculate exactly all the moments of the local density of states. Careful attention is paid to how the results change if the local de...
متن کامل“One-Sided” Log-Normal Distribution of Conductances for a Disordered Quantum Wire
We develop a simple systematic method, valid for all strengths of disorder, to obtain analytically the full distribution of the conductance P g for a quasi-one-dimensional wire in the absence of electronelectron interactions. We show that in the crossover region between the metallic and insulating regimes P g is highly asymmetric, given by an essentially “one-sided” log-normal distribution. For...
متن کاملEvaluation and Application of the Gaussian-Log Gaussian Spatial Model for Robust Bayesian Prediction of Tehran Air Pollution Data
Air pollution is one of the major problems of Tehran metropolis. Regarding the fact that Tehran is surrounded by Alborz Mountains from three sides, the pollution due to the cars traffic and other polluting means causes the pollutants to be trapped in the city and have no exit without appropriate wind guff. Carbon monoxide (CO) is one of the most important sources of pollution in Tehran air. The...
متن کامل‘One Sided’ Log-normal Distribution of Conductances of a Disordered Quantum Wire
We develop a simple systematic method, valid for all strengths of disorder, to obtain analytically for the first time the full distribution of conductance P (g) for a quasi one dimensional wire in the absence of electron-electron interaction. We show that in the crossover region between the metallic and insulating regimes, P (g) is highly asymmetric, given by an essentially ‘one sided’ log-norm...
