Prior-Data Fitted Networks for Causal Inference: a Simulation Study with Real-World Scenarios
Francisco Mourao, David Hajage, Daria Bystrova +4
Prior-Data Fitted Networks (PFNs) represent a paradigm shift in tabular data prediction. We present the principles of this new paradigm and evaluate two PFNs for estimating the ave…
Time Partitioning in Target Trial Emulation
Harold Tankpinou Zoumenou, Simon Ferreira, Charles Assaad +7
In target trial emulation, the treatment strategies that patients follow are inferred from the treatments they actually receive in routine care. However, in most settings, the outc…
One pathogen does not an epidemic make: A review of interacting contagions, diseases, beliefs, and stories
Laurent Hébert-Dufresne, Yong-Yeol Ahn, Antoine Allard +15
From pathogens and computer viruses to genes and memes, contagion models have found widespread utility across the natural and social sciences. Despite their success and breadth of…
Estimates of the reproduction ratio from epidemic surveillance may be biased in spatially structured populations
Piero Birello, Michele Re Fiorentin, Boxuan Wang +2
Accurate estimates of the reproduction ratio are crucial to project infectious disease epidemic evolution and guide public health response. Here, we prove that estimates of the rep…
Causal Discovery from Time Series with Hybrids of Constraint-Based and Noise-Based Algorithms
Daria Bystrova, Charles K. Assaad, Julyan Arbel +3
Constraint-based methods and noise-based methods are two distinct families of methods proposed for uncovering causal graphs from observational data. However, both operate under str…
The effect of delayed awareness and fatigue on the efficacy of self-isolation in epidemic control
Giulia de Meijere, Vittoria Colizza, Eugenio Valdano +1
The isolation of infectious individuals is a key measure of public health for the control of communicable diseases. However, involving a strong perturbation of daily life, it often…
Impact of urban structure on infectious disease spreading
Javier Aguilar, Aleix Bassolas, Gourab Ghoshal +8
The ongoing SARS-CoV-2 pandemic has been holding the world hostage for more than a year now. Mobility is key to viral spreading and its restriction is the main non-pharmaceutical i…
Partner support during pregnancy mediates social inequalities in maternal postpartum depression for non-migrant and first generation migrant women
Aurelie Nakamura, Fabienne El-Khoury, Anne-Laure Sutter-Dallay +4
Background An advantaged socioeconomic position (SEP) and satisfying social support during pregnancy (SSP) have been found to be protective factors of maternal postpartum depressio…
Maternal education and offspring birthweight for gestational age: the mediating effect of smoking during pregnancy
Aurelie Nakamura, Laura Pryor, Morgane Ballon +5
Background Small for gestational age (SGA) birthweight, a risk factor of infant mortality and delayed child development, is associated with maternal educational attainment. Materna…
Active and inactive quarantine in epidemic spreading on adaptive activity-driven networks
Marco Mancastroppa, Raffaella Burioni, Vittoria Colizza +1
We consider an epidemic process on adaptive activity-driven temporal networks, with adaptive behaviour modelled as a change in activity and attractiveness due to infection. By usin…
Interplay between competitive and cooperative interactions in a three-player pathogen system
Francesco Pinotti, Fakhteh Ghanbarnejad, Philipp Hövel +1
In ecological systems heterogeneous interactions between pathogens take place simultaneously. This occurs, for instance, when two pathogens cooperate, while at the same time multip…
Randomized reference models for temporal networks
Laetitia Gauvin, Mathieu Génois, Márton Karsai +4
Many dynamical systems can be successfully analyzed by representing them as networks. Empirically measured networks and dynamic processes that take place in these situations show h…
The Link Stream of Contacts in a Whole Hospital
Lucie Martinet, Christophe Crespelle, Eric Fleury +2
We analyse a huge and very precise trace of contact data collected by a network of sensors during 6 months on the entire population of a rehabilitation hospital. We investigate bot…
Dynamics of new strain emergence on a temporal network
Sukankana Chakraborty, Xavier R. Hoffmann, Marc G. Leguia +6
Multi-strain competition on networks is observed in many contexts, including infectious disease ecology, information dissemination or behavioral adaptation to epidemics. Despite a…
Spatial heterogeneity analyses identify limitations of epidemic alert systems: Monitoring influenza-like illness in France
Pavel Polyakov, Cécile Souty, Pierre-Yves Böelle +1
Surveillance data serving for epidemic alert systems are typically fully aggregated in space. However, epidemics may be spatially heterogeneous, undergoing distinct dynamics in dis…
Epidemic Threshold in Continuous-Time Evolving Networks
Eugenio Valdano, Michele Re Fiorentin, Chiara Poletto +1
Current understanding of the critical outbreak condition on temporal networks relies on approximations (time scale separation, discretization) that may bias the results. We propose…
Human mobility networks and persistence of rapidly mutating pathogens
Alberto Aleta, Andreia N. S. Hisi, Sandro Meloni +3
Rapidly mutating pathogens may be able to persist in the population and reach an endemic equilibrium by escaping hosts' acquired immunity. For such diseases, multiple biological, e…
Impact of spatially constrained sampling of temporal contact networks on the evaluation of the epidemic risk
Christian L. Vestergaard, Eugenio Valdano, Mathieu Génois +3
The ability to directly record human face-to-face interactions increasingly enables the development of detailed data-driven models for the spread of directly transmitted infectious…
Infection propagator approach to compute epidemic thresholds on temporal networks: impact of immunity and of limited temporal resolution
Eugenio Valdano, Chiara Poletto, Vittoria Colizza
The epidemic threshold of a spreading process indicates the condition for the occurrence of the wide spreading regime, thus representing a predictor of the network vulnerability to…
Characterising two-pathogen competition in spatially structured environments
Chiara Poletto, Sandro Meloni, Ashleigh Van Metre +3
Different pathogens spreading in the same host population often generate complex co-circulation dynamics because of the many possible interactions between the pathogens and the hos…
Analytical computation of the epidemic threshold on temporal networks
Eugenio Valdano, Luca Ferreri, Chiara Poletto +1
The time variation of contacts in a networked system may fundamentally alter the properties of spreading processes and affect the condition for large-scale propagation, as encoded…
Predicting epidemic risk from past temporal contact data
Eugenio Valdano, Chiara Poletto, Armando Giovannini +3
Understanding how epidemics spread in a system is a crucial step to prevent and control outbreaks, with broad implications on the system's functioning, health, and associated costs…
The diffusion dynamics of choice: From durable goods markets to fashion first names
Baptiste Coulmont, Virginie Supervie, Romulus Breban
Goods, styles, ideologies are adopted by society through various mechanisms. In particular, adoption driven by innovation is extensively studied by marketing economics. Mathematica…
Metapopulation epidemic models with heterogeneous mixing and travel behaviour
Andrea Apolloni, Chiara Poletto, Jose' J. Ramasco +2
The complex interplay between population movements in space and non-homogeneous mixing patterns have so far hindered the fundamental understanding of the conditions for spatial inv…
