Coevolution of epidemic dynamics and network topology driven by disease fatality and waning immunity
ThankGod I. S. Ikpe, Takayuki Hiraoka, Naoya Fujiwara
Epidemics on complex networks have been shown to exhibit dynamics that are strongly influenced by the topology of the network. However, it remains unclear how the topology of the n…
Message passing and cyclicity transition
Takayuki Hiraoka
Message passing, also known as belief propagation, is a versatile framework for analyzing models defined on graphs. Its most prototypical application is percolation; yet, the inter…
Epidemic reproduction numbers in spatial networks
Zahra Ghadiri, Jari Saramäki, Takayuki Hiraoka
The basic and effective reproduction numbers are widely used metrics for characterizing the dynamics of infectious disease epidemics. However, the interpretation of these numbers i…
Hierarchical organization of bursty trains in event sequences
Takayuki Hiraoka, Hang-Hyun Jo
Temporal sequences of discrete events that describe natural and social processes are often driven by non-Poisson dynamics. In addition to a heavy-tailed interevent time distributio…
Block-corrected Modularity for Community Detection
Hasti Narimanzadeh, Takayuki Hiraoka, Mikko Kivelä
Unknown node attributes in complex networks may introduce community structures that are important to distinguish from those driven by known attributes. We propose a block-corrected…
Geospatial analysis of toponyms in geotagged social media posts
Takayuki Hiraoka, Takashi Kirimura, Naoya Fujiwara
Place names, or toponyms, play an integral role in human representation and communication of geographic space. In particular, how people relate each toponym with particular locatio…
