Consequences of Social Network Structure for Epidemic Interventions

Abbas K. Rizi (Aalto University)

Abstract:
The COVID-19 pandemic has highlighted gaps in our understanding of how epidemics spread and the limitations of simple models in real-world scenarios, particularly when it comes to understanding herd immunity. In this presentation, we will focus on how the structure of contact networks affects the spread of disease and the effectiveness of interventions. We will explore the impact of pharmaceutical interventions, such as vaccination, and non-pharmaceutical measures, like contact tracing, on the trajectory of epidemics. We will consider factors such as behavior-based homophily, group structures, spatial characteristics, and the heterogeneities of contact networks. Additionally, we will introduce an advanced theoretical framework for analyzing temporal dynamics in networks, which is crucial for understanding how diseases spread, how information is disseminated, and how public transportation systems are accessed over time. Finally, we will connect the concept of temporal network reachability with percolation theory, a significant concept in studying complex systems.

Configuration models for random directed hypergraphs
Yanna J. Kraakman, Clara Stegehuis

Many complex systems show non-pairwise interactions, which can be captured by hypergraphs. In this work, we establish configuration models in which both the vertex and the hyperarc degrees are preserved for different classes of directed hypergraphs (containing self-loops, degenerate hyperarcs and/or multiple hyperarcs). We propose an edge-swapping method to uniformly sample from these configuration models and prove that this method indeed samples uniformly from the classes with self-loops and multiple hyperarcs, and that the method does not sample uniformly from classes without self-loops, or with self-loops and degenerate hyperarcs but without multiple hyperarcs. We present a partial result on the class with self-loops, but without degenerate hyperarcs or multiple hyperarcs.

قوس داستانی و خم‌های عاطفی در قصه‌ها

کِرْت وانه‌گت، نویسنده فقید آمریکایی، معتقد بود که تمام داستان‌ها را می‌توان بر اساس شکل روایی و قوس داستانی آن‌ها به دسته‌های انگشت‌شماری طبقه‌بندی کرد. این ادعا سال‌ها بعد به صورت کمی راستی‌آزمایی شد. در این ارائه ابتدا ادبیات داستان‌پردازی محاسباتی را مرور می‌کنیم. سپس نشان می‌دهیم که سریال‌های ترکی در سال‌های گذشته عمدتا چه نوع قوس داستانی داشته‌اند و کم و کیف موفقیتشان در گیشه چگونه بوده است.

Wastewater-based Epidemiology for COVID-19 Surveillance: A Survey

https://arxiv.org/abs/2403.15291

The pandemic of COVID-19 has imposed tremendous pressure on public health systems and social economic ecosystems over the past years. To alleviate its social impact, it is important to proactively track the prevalence of COVID-19 within communities. The traditional way to estimate the disease prevalence is to estimate from reported clinical test data or surveys. However, the coverage of clinical tests is often limited and the tests can be labor-intensive, requires reliable and timely results, and consistent diagnostic and reporting criteria. Recent studies revealed that patients who are diagnosed with COVID-19 often undergo fecal shedding of SARS-CoV-2 virus into wastewater, which makes wastewater-based epidemiology (WBE) for COVID-19 surveillance a promising approach to complement traditional clinical testing. In this paper, we survey the existing literature regarding WBE for COVID-19 surveillance and summarize the current advances in the area. Specifically, we have covered the key aspects of wastewater sampling, sample testing, and presented a comprehensive and organized summary of wastewater data analytical methods. Finally, we provide the open challenges on current wastewater-based COVID-19 surveillance studies, aiming to encourage new ideas to advance the development of effective wastewater-based surveillance systems for general infectious diseases.

علم شبکه و مدل‌سازی پخش بیماری‌ در حضور مداخله‌‌ها

در دو دهه گذشته، مدل‌سازی پخش بیماری‌های عفونی در جوامع به کمک ابزارهای فیزیک آماری و علم شبکه گسترش فراوانی داشته. در این ارائه، به اثرات ویژگی‌های شبکه‌‌های اجتماعی بر اثربخشی مداخله‌های دارویی و غیر دارویی همچون واکسیناسیون و رهگیری تماس می‌پردازیم. به طور خاص نشان می‌دهیم ویژگی‌هایی مانند ناهمگنی‌های ارتباطی، هوموفیلی رفتاری، اندازه گروه‌های اجتماعی و تحولات زمانی شبکه‌‌ها چگونه می‌توانند در بهبودبخشی اثرات مداخله‌ها نقش داشته باشند.
