Stationary Probability and First-Passage Time of Biased Random Walk
《Communications in Theoretical Physics》2016年第9期330-334,共5页李井文 唐沈立 徐新平 
Supported by the National Natural Science Foundation of China under Grant No.11205110;Shanghai Key Laboratory of Intelligent Information Processing(IIPL-2011-009);Innovative Training Program for College Students under Grant No.2015xj070
In this paper, we consider the stationary probability and first-passage time of biased random walk on 1D chain, where at each step the walker moves to the left and right with probabilities p and q respectively(0 p, q ...

Recurrence and Polya Number of General One-Dimensional Random Walks
《Communications in Theoretical Physics》2011年第8期293-296,共4页张晓琨 万晶 陆静菊 徐新平 
Supported by National Natural Science Foundation of China under Grant No. 10975057;Doctor Fund Project of Ministry of Education under Contract 20103201120003;the New Teacher Foundation of Soochow University under Contracts Q3108908, Q4108910;the Extracurricular Pesearch Foundation of Undergraduates under Grant No. KY2010056A
The recurrence properties of random walks can be characterized by P61ya number, i.e., the probability that the walker has returned to the origin at least once. In this paper, we consider recurrence properties for a ge...

Velocity and Dispersion for a Two-Dimensional Random Walk
《Communications in Theoretical Physics》2009年第10期627-630,共4页LI Jing-Hui 
Supported by National Natural Science Foundation of China under Grant No.10975079;by K.C.Wong Magna Fund in Ningbo University in China,and the Natural Science Foundation of Ningbo in China under Grant No.2008A61003
In the paper,we consider the transport of a two-dimensional random walk.The velocity and the dispersionof this two-dimensional random walk are derived.It mainly show that:(i)by controlling the values of the transition...

Continuous-Time Classical and Quantum Random Walk on Direct Product of Cayley Graphs
《Communications in Theoretical Physics》2009年第6期1003-1009,共7页S. Salimi M.A. Jafarizadeh 
In this paper we define direct product of graphs and give a recipe for obtaining probability of observing particle on vertices in the continuous-time classical and quantum random walk. In the recipe, the probability o...

On Origin of Power-Law Distributions in Self-Organized Criticality from Random Walk Treatment
《Communications in Theoretical Physics》2008年第1期249-251,共3页CAO Xiao-Feng DENG Zong-Wei YANG Chun-Bin 
The project supported in part by National Natural Science Foundation of China under Grant Nos.10635020 and 10475032;the Major Project of the Ministry of Education of China under Grant No.306022.
The origin of power-law distributions in self-organized criticality is investigated by treating the variation of the number of active sites in the system as a stochastic process. An avalanche is then regarded as a fir...

Scaling Argument of Anisotropic Random Walk
《Communications in Theoretical Physics》2005年第3期449-454,共6页XUBing-Zhen JINGuo-Jun WANGFei-Feng 
国家自然科学基金，浙江省自然科学基金
In this paper, we analytically discuss the scaling properties of the average square end-to-end distance < R-2 > for anisotropic random walk in D-dimensional space (D >= 2), and the returning probability P-n(r(0)) for ...

A General Random Walk Model of Molecular Motor
《Communications in Theoretical Physics》2003年第2X期237-240,共4页WANGXian-Ju AIBao-Quan LIUGuo-Tao LIULiang-Gang 
A general random walk model framework is presented which can be used to statistically describe the internal dynamics and external mechanical movement of molecular motors along filament track. The motion of molecular m...
