Examining the importance of existing relationships for co-offending: a temporal network analysis in Bogotá, Colombia (2005–2018)
Applied Network Science - Tập 8 - Trang 1-31 - 2023
This study aims to improve our understanding of criminal accomplice selection by studying the evolution of co-offending networks—i.e., networks that connect those who commit crimes together. To this end, we tested four growth mechanisms (popularity, reinforcement, reciprocity, and triadic closure) on three components observed in a network connecting criminal investigations (

Incorporating dynamic flight network in SEIR to model mobility between populations
Applied Network Science - Tập 6 - Trang 1-24 - 2021
Current efforts of modelling COVID-19 are often based on the standard compartmental models such as SEIR and their variations. As pre-symptomatic and asymptomatic cases can spread the disease between populations through travel, it is important to incorporate mobility between populations into the epidemiological modelling. In this work, we propose to modify the commonly-used SEIR model to account fo......

Modeling algorithmic bias: simplicial complexes and evolving network topologies
Applied Network Science - - 2022
Every day, people inform themselves and create their opinions on social networks. Although these platforms have promoted the access and dissemination of information, they may expose readers to manipulative, biased, and disinformative content—co-causes of polarization/radicalization. Moreover, recommendation algorithms, intended initially to enhance platform usage, are likely to augment such phenom......
Penalized inference of the hematopoietic cell differentiation network via high-dimensional clonal tracking
Applied Network Science - Tập 4 - Trang 1-26 - 2019
During their lifespan, stem- or progenitor cells have the ability to differentiate into more committed cell lineages. Understanding this process can be key in treating certain diseases. However, up until now only limited information about the cell differentiation process is known. The goal of this paper is to present a statistical framework able to describe the cell differentiation process at the ......
Fact-checking strategies to limit urban legends spreading in a segregated society
Applied Network Science - Tập 4 - Trang 1-19 - 2019
We propose a framework to study the spreading of urban legends, i.e., false stories that become persistent in a local popular culture, where social groups are naturally segregated by virtue of many (both mutable and immutable) attributes. The goal of this work is identifying and testing new strategies to restrain the dissemination of false information, focusing on the role of network polarization.......
Geometrical inspired pre-weighting enhances Markov clustering community detection in complex networks
Applied Network Science - Tập 6 - Trang 1-16 - 2021
Markov clustering is an effective unsupervised pattern recognition algorithm for data clustering in high-dimensional feature space. However, its community detection performance in complex networks has been demonstrating results far from the state of the art methods such as Infomap and Louvain. The crucial issue is to convert the unweighted network topology in a ‘smart-enough’ pre-weighted connecti......
Multilayer approach reveals organizational principles disrupted in breast cancer co-expression networks
Applied Network Science - Tập 5 - Trang 1-23 - 2020
The study of co-expression programs in the context of cancer can help to elucidate the genetic mechanisms that are altered and lead to the disease. The identification of gene co-expression patterns, unique to healthy profiles (and absent in cancer) is an important step in this direction. Networks are a good tool for achieving this as they allow to model local and global structural properties of th......
Organization and evolution of the UK far-right network on Telegram
Applied Network Science - Tập 7 - Trang 1-27 - 2022
The instant messaging platform Telegram has become popular among the far-right movements in the US and UK in recent years. These groups use public Telegram channels and group chats to disseminate hate speech, disinformation, and conspiracy theories. Recent works revealed that the far-right Telegram network structure is decentralized and formed of several communities divided mostly along ideologica......
Evolution of topics and hate speech in retweet network communities
Applied Network Science - Tập 6 - Trang 1-20 - 2021
Twitter data exhibits several dimensions worth exploring: a network dimension in the form of links between the users, textual content of the tweets posted, and a temporal dimension as the time-stamped sequence of tweets and their retweets. In the paper, we combine analyses along all three dimensions: temporal evolution of retweet networks and communities, contents in terms of hate speech, and disc......
