Modeling the Searching Behavior of Social Monkeys
, 2003 We discuss various features of the trajectories of spider monkeys looking for food in a tropical forest, as observed recently in an extensive {\it in situ} study. Some of the features observed can be interpreted as the result of social interactions.

Understanding Anomalous Transport in Intermittent Maps: From Continuous Time Random Walks to Fractals [PDF]
, 2004 We show that the generalized diffusion coefficient of a subdiffusive intermittent map is a fractal function of control parameters. A modified continuous time random walk theory yields its coarse functional form and correctly describes a dynamical phase ...

Asymptotic function for multi-growth surfaces using power-law noise
, 2002 Numerical simulations are used to investigate the multiaffine exponent $\alpha_q$ and multi-growth exponent $\beta_q$ of ballistic deposition growth for noise obeying a power-law distribution.

Recurrence and Polya number of general one-dimensional random walks
, 2010 The recurrence properties of random walks can be characterized by P\'{o}lya number, i.e., the probability that the walker has returned to the origin at least once.

Leapover lengths and first passage time statistics for L\'evy flights
, 2007 Exact results for the first passage time and leapover statistics of symmetric and one-sided Levy flights (LFs) are derived. LFs with stable index alpha are shown to have leapover lengths, that are asymptotically power-law distributed with index alpha for

Application of nonextensive statistics to particle and nuclear physics
, 2001 We present an overview of possible imprints of non-extensitivity in particle and nucler physics. Special emphasis is put on the intrinsic fluctuations present in the system under consideration as the possible source of nonextensivity.

A fluctuating environment as a source of periodic modulation
, 2007 We study the intermittent fluorescence of a single molecule, jumping from the "light on" to the "light off" state, as a Poisson process modulated by a fluctuating environment.

A prognosis oriented microscopic stock market model
, 1999 We present a new microscopic stochastic model for an ensemble of interacting investors that buy and sell stocks in discrete time steps via limit orders based on individual forecasts about the price of the stock.

Operator solutions for fractional Fokker-Planck equations
, 2012 We obtain exact results for fractional equations of Fokker-Planck type using evolution operator method. We employ exact forms of one-sided Levy stable distributions to generate a set of self-reproducing solutions.

Perpetual American options within CTRW's
, 2007 Continuous-time random walks are a well suited tool for the description of market behaviour at the smallest scale: the tick-to-tick evolution. We will apply this kind of market model to the valuation of perpetual American options: derivatives with no ...
