英文摘要：

Recommendations around epidemics tend to focus on individual behaviors, with much less efforts attempting to guide event cancellations and other collective behaviors since most models lack the higher-order structure necessary to describe large gatherings. Through a higher-order description of contagions on networks, we model the impact of a blanket cancellation of events larger than a critical size and find that epidemics can suddenly collapse when interventions operate over groups of individuals rather than at the level of individuals. We relate this phenomenon to the onset of mesoscopic localization, where contagions concentrate around dominant groups.

Confinement strategies in a simple SIR model

We propose a simple SIR model in order to investigate the impact of various confinement strategies on a most virulent epidemic. Our approach is motivated by the current COVID-19 pandemic. The main hypothesis is the existence of two populations of susceptible persons, one which obeys confinement and for which the infection rate does not exceed 1, and a population which, being non confined for various imperatives, can be substantially more infective. The model, initially formulated as a differential system, is discretised following a specific procedure, the discrete system serving as an integrat…

揭示流行病传播中尺度干预的时间网络潜在因素

Revealing latent factors of temporal networks for mesoscale intervention in epidemic spread

在时间网络中，流行病缓解的传统观点取决于识别具有特定特征或网络角色的节点。然而，随之而来的基于个人的控制策略，很难在实践中进行，并忽略了重要的拓扑和时间模式之间的相关性。在这里，我们采用中观的视角，并提出了一个原则性的框架，以确定在多个尺度的集体特征，并排名其重要性的流行病传播。我们使用张量分解技术来建立一个时间网络的附加表示的介观结构，如凝聚力集群和时间本地化的混合模式。这种表示允许确定单个介观结构对流行病传播的影响，并评估去除所选结构的有针对性的干预措施的效果。我们说明了这种方法使用高分辨率的社交网络数据在学校面对面的互动，并表明我们的方法提供了有效的中尺度干预措施的设计。

Smart Testing and Selective Quarantine for the Control of Epidemics

This paper is based on the observation that, during Covid-19 epidemic, the choice of which individuals should be tested has an important impact on the effectiveness of selective confinement measures. This decision problem is closely related to the problem of optimal sensor selection, which is a very active research subject in control engineering. The goal of this paper is to propose a policy to smartly select the individuals to be tested. The main idea is to model the epidemics as a stochastic dynamic system and to select the individual to be tested accordingly to some optimality criteria, e.g…

社区结构复杂网络上的传染病传播

Epidemic spreading on complex networks with community structures

许多现实世界的网络都显示出社区结构。我们研究了两种随机图模型，它们创建了一个与给定网络具有相似社区结构的网络。一个模型保留了原始网络的精确社区结构，而另一个模型只保留了社区集合和顶点度。这些模型表明，社区结构是网络上的渗流过程，如信息扩散或病毒传播的行为的一个重要决定因素：社区结构既可以是\textit{enforce}，也可以是\textit{inhibit}扩散过程。我们的模型进一步表明，重要的是介观社区集。社区的确切内部结构几乎不影响网络中的渗流过程。这种不敏感性可能是由于社区的相对密集。

通过在中观层面瞄准集体影响者来分割网络

Fragmenting networks by targeting collective influencers at a mesoscopic level

保护网络免受传染病、恶意软件和有害病毒信息传播等流行过程的一种实用方法是预先删除一些有影响的节点，将网络分割成小的组件。由于确定删除节点的最佳顺序是一个计算困难的问题，已经提出了各种近似算法，以有效地通过顺序删除节点来分割网络。Morone和Makse提出了一种利用给定网络的非回溯矩阵的算法，该算法优于现有的各种算法。事实上，许多经验网络具有社区结构，这与原始算法所基于的局部树状结构假设相矛盾。我们开发了一种免疫算法，通过协同结合Morone-Makse算法和粗粒化的网络中，我们把一个社区作为一个超级节点。通过这种方式，我们的目标是以合理的计算成本确定连接不同社区的节点。该算法比Morone-Makse算法和其他算法在具有社团结构的网络上更有效。

A viral load-based model for epidemic spread on spatial networks

In this paper, we propose a Boltzmann-type kinetic model of the spreading of an infectious disease on a network. The latter describes the connections among countries, cities or districts depending on the spatial scale of interest. The disease transmission is represented in terms of the viral load of the individuals and is mediated by social contacts among them, taking into account their displacements across the nodes of the network. We formally derive the hydrodynamic equations for the density and the mean viral load of the individuals on the network and we analyse the large-time trends of the…

复杂网络局部免疫的全局有效性

Global efficiency of local immunization on complex networks

流行病以各种形式出现：传染病在我们稀疏的性网络中传播，谣言和疾病在我们密集得多的社会交往中传播，或者病毒在互联网上传播。随着大型数据库和高效分析算法的出现，这些过程可以更好地预测和控制。在这项研究中，我们使用不同的网络组织的特点，以确定有影响力的传播者在17个不同性质的经验网络使用2个流行病模型。我们发现，一个明智的选择的本地措施，无论是在微观尺度上的网络的连通性或在中观尺度上的社区结构的基础上，相比有利的全球措施，如介数中心，在效率，实用性和鲁棒性。我们还开发了一个分析框架，突出了不同的流行病制度的特征规模的过渡。这就可以决定在特定情况下应采取哪种地方措施来管理免疫接种。

Predictability: Can the turning point and end of an expanding epidemic be precisely forecast?

No, they can't. Epidemic spread is characterized by exponentially growing dynamics, which are intrinsically unpredictable. The time at which the growth in the number of infected individuals halts and starts decreasing cannot be calculated with certainty before the turning point is actually attained; neither can the end of the epidemic after the turning point. An SIR model with confinement (SCIR) illustrates how lockdown measures inhibit infection spread only above a threshold that we calculate. The existence of that threshold has major effects in predictability: A Bayesian fit to the COVID-19 …

Network structured kinetic models of social interactions

The aim of this paper is to study the derivation of appropriate meso- and macroscopic models for interactions as appearing in social processes. There are two main characteristics the models take into account, namely a network structure of interactions, which we treat by an appropriate mesoscopic description, and a different role of interacting agents. The latter differs from interactions treated in classical statistical mechanics in the sense that the agents do not have symmetric roles, but there is rather an active and a passive agent. We will demonstrate how a certain form of kinetic equatio…

Two-level modeling of quarantine

Continuum models of epidemics do not take into account the underlying microscopic network structure of social connections. This drawback becomes extreme during quarantine when most people dramatically decrease their number of social interactions, while others (like cashiers in grocery stores) continue maintaining hundreds of contacts per day. We formulate a two-level model of quarantine. On a microscopic level, we model a single neighborhood assuming a star-network structure. On a mesoscopic level, the neighborhoods are placed on a two-dimensional lattice with nearest neighbors interactions. T…

COVID-19 spreading under containment actions

We propose an epidemiological model that includes the mobility patterns of the individuals, in the spirit to those considered in (Barmak, 2011, 2016) and (Medus, 2011). We assume that people move around in a city of 120x120 blocks with 300 inhabitants in each block. The mobility pattern is associated to a complex network in which nodes represent blocks while the links represent the traveling path of the individuals. We implemented three confinement strategies in order to mitigate the disease spreading: 1) global confinement, 2) partial restriction to mobility, and 3) localized confinement. In …
