Abstract null null This work proposed an approach to test the efficient market hypothesis (EMH) based on the singular value decomposition (SVD) entropy. The entropy is computed from the singular value distribution of a matrix formed by lagged returns up to a scale null null null n null null . To decide whether a time series is predictable, the estimated SVD entropy was compared with a reference entropy obtained from uncorrelated (white noise) time series of the same size. The application of the ...

Abstract null null Affected by geographical or social factors, human communities are organized with changeless groups for teamwork. Within groups, defection dominates because the payoffs of defectors are often higher than those of cooperators; among groups, higher cooperation level makes individuals wealthier. For the previous mechanism of evolutionary dynamics leading individuals to imitate the rich in their groups, defective strategy evolves. However, individuals who belong to different groups...

Abstract null null In the study of pedestrian evacuation dynamics, pedestrian aggressiveness is important to consider as it potentially impacts evacuation efficiency. A representative example is the ‘faster-is-slower’ phenomenon. In reality, a crowd is a mixture of patient and impatient pedestrians, rather than a collection of like individuals. The impact of such heterogeneity has been reported in previous studies; however, these studies are all based on handcrafted solutions. In this study, we ...

Abstract null null We studied dynamic magnetic properties and compensation behaviors of a mixed spin (1/2, 1) Ising ferrimagnetic system on a hexagonal lattice within the path probability method that contains more than one rate constants and the average dynamic order parameters were coupled. We found the phases in the system by solving the average dynamic magnetizations. We examined the thermal features of dynamic magnetizations to characterize the nature of the dynamic phase transitions (DPTs) ...

Abstract null null With the rapid development of social economy, the traffic volume of urban roads has raised significantly, which has led to increasingly serious urban traffic congestion problems, and has caused much inconvenience to people’s travel. By focusing on the complexity and long-term dependence of traffic flow sequences on urban road, this paper considered the traffic flow data and weather conditions of the road section comprehensively, and proposed a short-term traffic flow predictio...

Abstract null null Fractal networks are a special class of self-organized networks in the real world. Several network models have been proposed to explain fractality, but most of them are intentionally designed to generate self-similar structures. However, considering that most real-world networks appear to be self-organized by random and local events, random phenomena occurring in networks are expected to be more relevant for explaining fractality than intentional design. In this study, we focu...

Abstract null null It is known that the vaccination is essential for suppressing the periodic prevalence of an infectious disease, while the vaccination decision is influenced by external factors. Whether or not to take vaccination depends not only on the expected benefit of individual, but also on the behavior of others. Nowadays, the speed of information transmission on the social media is fast with wide range, which extremely expands the scope of imitation, but it is unknown whether it is ben...

Abstract null null A minimalistic multi-agent Parrondo’s game structure with network evolution (Game A) and branching dependent on the number of wins and losses of neighbors (Game B) was previously introduced, indicating that Parrondo’s paradox occurs, in which a losing strategy and a neutral strategy combine to yield a winning one. Using a similar Game B’s structure and introducing a new Game A’s structure with competition and cooperation behaviors, we further analyze the influences of network ...
