High-Dimensional Contact Network Epidemiology [PDF]
Epidemiologia, 2023 Contact network models are recent alternatives to equation-based models in epidemiology. In this paper, the spread of disease is modeled on contact networks using bond percolation. The weight of the edges in the contact graphs is determined as a function

Contact network analysis of COVID-19 Delta variant outbreak in urban China —based on 2,050 confirmed cases in Xi’an, China [PDF]
BMC Public Health, 2022 Background The purpose of this paper is to study how the Delta variant spread in a China city, and to what extent the non-pharmaceutical prevention measures of local government be effective by reviewing the contact network of COVID-19 cases in Xi’an ...

NiemaGraphGen: A memory-efficient global-scale contact network simulation toolkit [PDF]
GigaByte, 2022 Epidemic simulations require the ability to sample contact networks from various random graph models. Existing methods can simulate city-scale or even country-scale contact networks, but they are unable to feasibly simulate global-scale ...

Indirect interactions influence contact network structure and diffusion dynamics [PDF]
Royal Society Open Science, 2019 Interaction patterns at the individual level influence the behaviour of diffusion over contact networks. Most of the current diffusion models only consider direct interactions, capable of transferring infectious items among individuals, to build ...

Approximate inference for longitudinal mechanistic HIV contact network [PDF]
Applied Network ScienceNetwork models are increasingly used to study infectious disease spread. Exponential Random Graph models have a history in this area, with scalable inference methods now available. An alternative approach uses mechanistic network models.

ENDOGENOUS JOB CONTACT NETWORKS [PDF]
International Economic Review (forthcoming), 2010 We develop a model where workers, anticipating the risk of becoming unemployed, invest in connections in order to access information about available jobs that other workers may have. The investment in connections is high when the job separation rate in the labor market is moderate, whereas it is low for either low or high levels of job separation rate.

Two-Way Contact Network Modeling for Identifying the Route of COVID-19 Community Transmission
Informatics, 2021 In this study, we address the problem originated from the fact that “The Corona 19 Epidemiological Research Support System,” developed by the Korea Centers for Disease Control and Prevention, is limited to analyzing the Global Positioning System (GPS ...
