Herd Immunity and Epidemic Size in Networks with Vaccination Homophily
Takayuki Hiraoka, Abbas K. Rizi, Mikko Kivelä +1
We study how the herd immunity threshold and the expected epidemic size depend on homophily with respect to vaccine adoption. We find that the presence of homophily considerably in…
Limits of Multilayer Diffusion Network Inference in Social Media Research
Yan Xia, Ted Hsuan Yun Chen, Mikko Kivelä
Information on social media spreads through an underlying diffusion network that connects people of common interests and opinions. This diffusion network often comprises multiple l…
Directed Percolation in Random Temporal Network Models with Heterogeneities
Arash Badie-Modiri, Abbas K. Rizi, Márton Karsai +1
The event graph representation of temporal networks suggests that the connectivity of temporal structures can be mapped to a directed percolation problem. However, similar to perco…
Directed Percolation in Temporal Networks
Arash Badie-Modiri, Abbas K. Rizi, Márton Karsai +1
Connectivity and reachability on temporal networks, which can describe the spreading of a disease, decimation of information or the accessibility of a public transport system over…
Graphlets in multilayer networks
Sallamari Sallmen, Tarmo Nurmi, Mikko Kivelä
Representing various networked data as multiplex networks, networks of networks and other multilayer networks can reveal completely new types of structures in these system. We intr…
Adaptive and optimized COVID-19 vaccination strategies across geographical regions and age groups
Jeta Molla, Alejandro Ponce de León Chávez, Takayuki Hiraoka +3
We evaluate the efficiency of various heuristic strategies for allocating vaccines against COVID-19 and compare them to strategies found using optimal control theory. Our approach…
