Evaluating the impact of incomplete contact tracing data on urban epidemic dynamics
Min-Kyung Chae, Woo-Sik Son, Sang Hoon Lee
Contact tracing (CT) is a frontline measure against emerging epidemics, yet in practice it is never complete. The quantitative impact of missing information -- such as untraced cas…
Global decomposition of networks into multiple cores formed by local hubs
Wonhee Jeong, Unjong Yu, Sang Hoon Lee
Networks are ubiquitous in various fields, representing systems where nodes and their interconnections constitute their intricate structures. We introduce a network decomposition s…
Revisiting small-world network models: Exploring technical realizations and the equivalence of the Newman-Watts and Harary models
Seora Son, Eun Ji Choi, Sang Hoon Lee
We address the relatively less known facts on the equivalence and technical realizations surrounding two network models showing the "small-world" property, namely the Newman-Watts…
Exploring 3D community inconsistency in human chromosome contact networks
Dolores Bernenko, Sang Hoon Lee, Ludvig Lizana
Researchers developed chromosome capture methods such as Hi-C to better understand DNA's 3D folding in nuclei. The Hi-C method captures contact frequencies between DNA segment pair…
Degree distributions under general node removal: Power-law or Poisson?
Mi Jin Lee, Jung-Ho Kim, Kwang-Il Goh +3
Perturbations made to networked systems may result in partial structural loss, such as a blackout in a power-grid system. Investigating the resultant disturbance in network propert…
Refinement for community structures of bipartite networks
Sang Hoon Lee
Bipartite networks composed of dichotomous node sets are ubiquitous in nature and society. Partly for simplicity's sake, many studies have focused on their projection onto their un…
Mesoscale properties of mutualistic networks in ecosystems
Sang Hoon Lee
Uncovering structural properties of ecological networks is a crucial starting point of studying the system's stability in response to various types of perturbations. We analyze pol…
Uncovering hidden dependency in weighted networks via information entropy
Mi Jin Lee, Eun Lee, Byunghwee Lee +3
Interactions between elements, which are usually represented by networks, have to delineate potentially unequal relationships in terms of their relative importance or direction. Th…
Early onset of structural inequality in the formation of collaborative knowledge, Wikipedia
Jinhyuk Yun, Sang Hoon Lee, Hawoong Jeong
We perform an in-depth analysis on the inequality in 863 Wikimedia projects. We take the complete editing history of 267,304,095 Wikimedia items until 2016, which not only covers e…
Intellectual interchanges in the history of the massive online open-editing encyclopedia, Wikipedia
Jinhyuk Yun, Sang Hoon Lee, Hawoong Jeong
Wikipedia is a free Internet encyclopedia with an enormous amount of content. This encyclopedia is written by volunteers with various backgrounds in a collective fashion; anyone ca…
Time-dependent community structure in legislation cosponsorship networks in the Congress of the Republic of Peru
Sang Hoon Lee, José Manuel Magallanes, Mason A. Porter
We study community structure in time-dependent legislation cosponsorship networks in the Peruvian Congress, and we compare them briefly to legislation cosponsorship networks in the…
Density-based and transport-based core-periphery structures in networks
Sang Hoon Lee, Mihai Cucuringu, Mason A. Porter
Networks often possess mesoscale structures, and studying them can yield insights into both structure and function. It is most common to study community structure, but numerous oth…
Matchmaker, Matchmaker, Make Me a Match: Migration of Populations via Marriages in the Past
Sang Hoon Lee, Robyn Ffrancon, Daniel M. Abrams +2
The study of human mobility is both of fundamental importance and of great potential value. For example, it can be leveraged to facilitate efficient city planning and improve preve…
