Modeling s-t Path Availability to Support Disaster Vulnerability Assessment of Network Infrastructure
The maintenance of system flow is critical for effective network operation. Any type of disruption to network facilities (arcs/nodes) potentially risks loss of service, leaving users without access…

Component Ratios of Independent and Herding Betters in a Racetrack Betting Market
We study the time series data of the racetrack betting market in the Japan Racing Association (JRA). As the number of votes t increases, the win bet fraction x(t) converges to the final win bet…

Spreading Dynamics Following Bursty Human Activity Patterns
We study the susceptible-infected model with power-law waiting time distributions P(τ) τ-α, as a model of spreading dynamics under heterogeneous human activity patterns. We found that the…

Differential influence of instruments in nuclear core activity evaluation by data assimilation
The global activity fields of a nuclear core can be reconstructed using data assimilation. Data assimilation allows to combine measurements from instruments, and information from a model, to evaluate…

Quantifying long-range correlations in complex networks beyond nearest neighbors
We propose a fluctuation analysis to quantify spatial correlations in complex networks. The approach considers the sequences of degrees along shortest paths in the networks and quantifies the…
