In this paper, we numerically study energy dissipation per unit time per car Ed in the Nagel–Schreckenberg (NS) model. Numerical results show that there is a critical density over which energy dissipation occurs, but below which no energy loss happens in the deterministic NS model. Energy...

We suggest that there exists a critical point H=0.70 of the local Hölder exponent H(t) for describing the weak stationary (stationary for short) property of the modified multifractional Gaussian noise (mmGn) from the point of view of engineering. More precisely, when H(t)0.70 for t∈[0,∞],...

The contributions of this short paper are two-fold. We shall show two interesting properties of fractional Gaussian noise (fGn), namely, its bandlimitedness and lag-limitedness. The computation formulas for the maximum frequency of bandlimited fGn and the maximum lag of lag-limited fGn are...

Traders develop and adopt different trading strategies attempting to maximize their profits in financial markets. These trading strategies not only result in specific topological structures in trading networks, which connect the traders with the pairwise buy–sell relationships, but also have...

This article employs the number of news appeared in Baidu News as a novel proxy for information arrival and investigates the validation of the Mixture of Distribution Hypothesis (MDH) using a sample of SME PRICE INDEX in China. The empirical results reveal a positive impact of internet...

In this paper, we build undirected weighted networks to study herding behavior among analysts and to analyze the characteristics and the structure of these networks. We then construct a new indicator based on the average degree of nodes and the average weighted clustering coefficient to research...

In this paper we numerically study the probability Pac of the occurrence of traffic accidents in the Nagel–Schreckenberg (NS) model with velocity-dependent randomization (VDR). Numerical results show that there is a critical density over which car accidents occur, but below which no car...

The compressibility isotherms of three samples of He-N2 mixtures containing, respectively, 25,50 and 75 mol% helium have been measured at 298.15 K and at pressures between 2 and 10 kbar using a modified stepwise expansion method. The accuracy of the measurements is estimated to be better than...

In this article, the effects of irreversible detachments of particles in totally asymmetric simple exclusion processes (TASEPs) with extended particles which occupy more than one lattice site, are investigated. First, an approximate mean-field theory is used to calculate phase diagrams and...

This paper studies the switching of trading strategies and its effect on the market volatility in a continuous double auction market. We describe the behavior when some uninformed agents, who we call switchers, decide whether or not to pay for information before they trade. By paying for the...
