1. Modelling Biological and Ecological Systems with the Calculus of Wrapped Compartments

Abstract

The modelling and analysis of biological systems has deep roots in Mathematics, specifically in the field of Ordinary Differential Equations. Alternative approaches based on formal calculi, often derived from process algebras or term rewriting systems, provide a quite complementary way to analyse the behaviour of biological systems. These calculi allow to cope in a natural way with notions like compartments and membranes, which are not easy (sometimes impossible) to handle with purely numerical approaches, and are often based on stochastic simulation methods. The Calculus of Wrapped Compartments is a framework based on stochastic multiset rewriting in a compartmentalised setting used for the description of biological and ecological systems. We provide an extended presentation of the Calculus of Wrapped Compartments, sketch a few modelling guidelines to encode biological and ecological interactions, show how spatial properties can be handled within the framework and define a hybrid simulation algorithm. Several applications in Biology and Ecology are proposed as modelling case studies., Comment: arXiv admin note: text overlap with arXiv:1505.01985

4. A Social Network Simulation Game to Raise Awareness of Privacy among School Children

Author

Bioglio, Livio, Capecchi, Sara, Peiretti, Federico, Sayed, Dennis, Torasso, Antonella, and Pensa, Ruggero G.

Abstract

In this paper, we address the problem of enhancing young people's awareness of the mechanisms involving privacy in online social networks by presenting an innovative approach based on gamification. In particular, we propose a web application that allows kids and teenagers to experience the typical dynamics of information spread through a realistic interactive simulation. Under the supervision of the teacher, the students are inserted in a small artificial social graph, and through the different stages of game, they can post sentences with different levels of sensitivity, and "like" or share messages published by friends. At the end of game session, the application calculate multiple behavioral scores that can be used by the teacher to raise the curiosity of the students and stimulate discussions. Moreover, a complete interactive report is generated to analyze every individual action of the terminated game sessions. Our educational tool has been employed within an extensive experimental study involving more than 450 kids and 22 teachers in seven Italian primary school institutes. The results show that our approach is stimulating and supports teachers in helping kids discover and recognize potential privacy risks in social network activities.

21. Anatomy of digital contact tracing: Role of age, transmission setting, adoption and case detection

Author

Arregui García, Beatriz, Moreno López, Jesús A., Bentkowski, Piotr, Bioglio, Livio, Pinotti, Francesco, Boëlle, Pierre-Yves, Barrat, Alain, Colizza, Vittoria, Poletto, Chiara, Arregui García, Beatriz, Moreno López, Jesús A., Bentkowski, Piotr, Bioglio, Livio, Pinotti, Francesco, Boëlle, Pierre-Yves, Barrat, Alain, Colizza, Vittoria, and Poletto, Chiara

Abstract

The efficacy of digital contact tracing against coronavirus disease 2019 (COVID-19) epidemic is debated: Smartphone penetration is limited in many countries, with low coverage among the elderly, the most vulnerable to COVID-19. We developed an agent-based model to precise the impact of digital contact tracing and household isolation on COVID-19 transmission [1]. The model, calibrated on French population, integrates demographic, contact and epidemiological information to describe exposure and transmission of COVID- 19. We explored realistic levels of case detection, app adoption, population immunity, and transmissibility. Assuming a reproductive ratio R = 2.6 and 50% detection of clinical cases, a ~20% app adoption reduces peak incidence by ~35%. With R = 1.7, >30% app adoption lowers the epidemic to manageable levels. Higher coverage among adults, playing a central role in COVID-19 transmission, yields an indirect benefit for the elderly. These results may inform the inclusion of digital contact tracing within a response plan against COVID-19 and future emerging disease epidemics.

Abstract

The article presents a study of the role of age, transmission setting, adoption and case detection in France in the efficacy of digital contract tracing against the coronavirus disease 2019 (COVID-19) pandemic. Topics discussed include the use of epidemiological and viral shedding studies in order to parametrize the natural history of the infection, reduction in peak incidence in household isolation, and the importance of app adoption in determining the efficacy of digital contract tracing.
