Biomedical Open Source Software: Crucial Packages and Hidden Heroes
Eva Maxfield Brown, Stephan Druskat, Laurent Hébert-Dufresne +5
Despite the importance of scientific software for research, it is often not formally recognized and rewarded. This is especially true for foundational libraries, which are hidden b…
Temporal and probabilistic comparisons of epidemic interventions
Mariah C. Boudreau, Andrea J. Allen, Nicholas J. Roberts +2
Forecasting disease spread is a critical tool to help public health officials design and plan public health interventions. However, the expected future state of an epidemic is not…
Source-sink cooperation dynamics constrain institutional evolution in a group-structured society
Laurent Hébert-Dufresne, Timothy M. Waring, Guillaume St-Onge +6
Societies change through time, entailing changes in behaviors and institutions. We ask how social change occurs when behaviors and institutions are interdependent. We model a group…
When the Echo Chamber Shatters: Examining the Use of Community-Specific Language Post-Subreddit Ban
Milo Z. Trujillo, Samuel F. Rosenblatt, Guillermo de Anda Jáuregui +4
Community-level bans are a common tool against groups that enable online harassment and harmful speech. Unfortunately, the efficacy of community bans has only been partially studie…
Impact and dynamics of hate and counter speech online
Joshua Garland, Keyan Ghazi-Zahedi, Jean-Gabriel Young +2
Citizen-generated counter speech is a promising way to fight hate speech and promote peaceful, non-polarized discourse. However, there is a lack of large-scale longitudinal studies…
Network comparison and the within-ensemble graph distance
Harrison Hartle, Brennan Klein, Stefan McCabe +4
Quantifying the differences between networks is a challenging and ever-present problem in network science. In recent years a multitude of diverse, ad hoc solutions to this problem…
The unintended consequences of inconsistent pandemic control policies
Benjamin M. Althouse, Brendan Wallace, Brendan Case +4
Controlling the spread of COVID-19 - even after a licensed vaccine is available - requires the effective use of non-pharmaceutical interventions: physical distancing, limits on gro…
Localization, epidemic transitions, and unpredictability of multistrain epidemics with an underlying genotype network
Blake J. M. Williams, Guillaume St-Onge, Laurent Hébert-Dufresne
Mathematical disease modelling has long operated under the assumption that any one infectious disease is caused by one transmissible pathogen spreading among a population. This par…
Countering hate on social media: Large scale classification of hate and counter speech
Joshua Garland, Keyan Ghazi-Zahedi, Jean-Gabriel Young +2
Hateful rhetoric is plaguing online discourse, fostering extreme societal movements and possibly giving rise to real-world violence. A potential solution to this growing global pro…
Limits of Individual Consent and Models of Distributed Consent in Online Social Networks
Juniper Lovato, Antoine Allard, Randall Harp +2
Personal data are not discrete in socially-networked digital environments. A user who consents to allow access to their profile can expose the personal data of their network connec…
Immunization Strategies in Networks with Missing Data
Samuel F. Rosenblatt, Jeffrey A. Smith, G. Robin Gauthier +1
Network-based intervention strategies can be effective and cost-efficient approaches to curtailing harmful contagions in myriad settings. As studied, these strategies are often imp…
Master equation analysis of mesoscopic localization in contagion dynamics on higher-order networks
Guillaume St-Onge, Vincent Thibeault, Antoine Allard +2
Simple models of infectious diseases tend to assume random mixing of individuals, but real interactions are not random pairwise encounters: they occur within various types of gathe…
Efficient sampling of spreading processes on complex networks using a composition and rejection algorithm
Guillaume St-Onge, Jean-Gabriel Young, Laurent Hébert-Dufresne +1
Efficient stochastic simulation algorithms are of paramount importance to the study of spreading phenomena on complex networks. Using insights and analytical results from network s…
Edge fires drive the shape and stability of tropical forests
Laurent Hébert-Dufresne, Adam F. A. Pellegrini, Uttam Bhat +3
In tropical regions, fires propagate readily in grasslands but typically consume only edges of forest patches. Thus forest patches grow due to tree propagation and shrink by fires…
Asymmetric percolation drives a double transition in sexual contact networks
Antoine Allard, Benjamin M. Althouse, Samuel V. Scarpino +1
Zika virus (ZIKV) exhibits unique transmission dynamics in that it is concurrently spread by a mosquito vector and through sexual contact. We show that this sexual component of ZIK…
Finite size analysis of the detectability limit of the stochastic block model
Jean-Gabriel Young, Patrick Desrosiers, Laurent Hébert-Dufresne +2
It has been shown in recent years that the stochastic block model (SBM) is sometimes undetectable in the sparse limit, i.e., that no algorithm can identify a partition correlated w…
Exotic phase transitions of k-cores in clustered networks
Uttam Bhat, Munik Shrestha, Laurent Hébert-Dufresne
The giant -core --- maximal connected subgraph of a network where each node has at least neighbors --- is important in the study of phase transitions and in applications of…
Strategic tradeoffs in competitor dynamics on adaptive networks
Laurent Hébert-Dufresne, Antoine Allard, Pierre-André Noël +2
Recent empirical work highlights the heterogeneity of social competitions such as political campaigns: proponents of some ideologies seek debate and conversation, others create ech…
Dynamics of beneficial epidemics
Andrew Berdahl, Christa Brelsford, Caterina De Bacco +12
Pathogens can spread epidemically through populations. Beneficial contagions, such as viruses that enhance host survival or technological innovations that improve quality of life,…
Growing networks of overlapping communities with internal structure
Jean-Gabriel Young, Laurent Hébert-Dufresne, Antoine Allard +1
We introduce an intuitive model that describes both the emergence of community structure and the evolution of the internal structure of communities in growing social networks. The…
Multi-scale structure and topological anomaly detection via a new network statistic: The onion decomposition
Laurent Hébert-Dufresne, Joshua A. Grochow, Antoine Allard
We introduce a new network statistic that measures diverse structural properties at the micro-, meso-, and macroscopic scales, while still being easy to compute and easy to interpr…
General and exact approach to percolation on random graphs
Antoine Allard, Laurent Hébert-Dufresne, Jean-Gabriel Young +1
We present a comprehensive and versatile theoretical framework to study site and bond percolation on clustered and correlated random graphs. Our contribution can be summarized in t…
Prudent behaviour accelerates disease transmission
Samuel V. Scarpino, Antoine Allard, Laurent Hebert-Dufresne
Infectious diseases often spread faster near their peak than would be predicted given early data on transmission. Despite the commonality of this phenomena, there are no known gene…
Complex networks as an emerging property of hierarchical preferential attachment
Laurent Hébert-Dufresne, Edward Laurence, Antoine Allard +2
Real complex systems are not rigidly structured; no clear rules or blueprints exist for their construction. Yet, amidst their apparent randomness, complex structural properties uni…
