Quasi-compactness of transfer operators for topological Markov shifts with holes
Haruyoshi Tanaka
We consider transfer operators for topological Markov shift (TMS) with countable states and with holes which are -cylinders. As main results, if the closed system of the shift h…
Detrended fluctuation analysis of earthquake data
Takumi Kataoka, Tomoshige Miyaguchi, Takuma Akimoto
The detrended fluctuation analysis (DFA) is extensively useful in stochastic processes to unveil the long-term correlation. Here, we apply the DFA to point processes that mimick ea…
A piecewise linear model of self-organized hierarchy formation
Tomoshige Miyaguchi, Takamasa Miki, Ryota Hamada
The Bonabeau model of self-organized hierarchy formation is studied by using a piecewise linear approximation to the sigmoid function. Simulations of the piecewise-linear agent mod…
Brownian motion with alternately fluctuating diffusivity: Stretched-exponential and power-law relaxation
Tomoshige Miyaguchi, Takashi Uneyama, Takuma Akimoto
We investigate Brownian motion with diffusivity alternately fluctuating between fast and slow states. We assume that sojourn-time distributions of these two states are given by exp…
Relaxation Functions of Ornstein-Uhlenbeck Process with Fluctuating Diffusivity
Takashi Uneyama, Tomoshige Miyaguchi, Takuma Akimoto
We study a relaxation behavior of an Ornstein-Uhlenbeck (OU) process with a time-dependent and fluctuating diffusivity. In this process, the dynamics of a position vector is modele…
Electron paramagnetic resonance enhanced crystal field analysis for low point-group symmetry systems: C sites in Sm:CaF/SrF
Sebastian P Horvath, Jon-Paul R Wells, Michael F Reid +2
We present a comprehensive spectroscopic study of C point-group symmetry sites in Sm:CaF/SrF codoped with either NaF or LiF. Data includes electron paramagnet…
