Structure of a Media Co-occurrence Network [PDF]
CoRR, 2016 Social networks have been of much interest in recent years. We here focus on a network structure derived from co-occurrences of people in traditional newspaper media. We find three clear deviations from what can be expected in a random graph. First, the average degree in the empirical network is much lower than expected, and the average weight of a ...

Network Inference From Co-Occurrences [PDF]
IEEE Transactions on Information Theory, 2008 The recovery of network structure from experimental data is a basic and fundamental problem. Unfortunately, experimental data often do not directly reveal structure due to inherent limitations such as imprecision in timing or other observation mechanisms.

CO-OCCURRENCE NETWORK OF REUTERS NEWS [PDF]
International Journal of Modern Physics C, 2008 Networks describe various complex natural systems including social systems. We investigate the social network of co-occurrence in Reuters-21578 corpus, which consists of news articles that appeared in the Reuters newswire in 1987. People are represented as vertices and two persons are connected if they co-occur in the same article.

A guide for comparing microbial co‐occurrence networks
iMeta, 2023 The article provides a pipeline for comparing microbial co-occurrence networks based on the R microeco package and meconetcomp package. It has high flexibility and expansibility and can help users efficiently compare networks built from different groups of samples or different construction approaches.

Topological Properties of Co-Occurrence Networks in Published Gene Expression Signatures
Bioinformatics and Biology Insights, 2008 Meta-analysis of high-throughput gene expression data is often used for the interpretation of proprietary gene expression data sets. We have recently shown that co-occurrence patterns of gene expression in published cancer-related gene expression ...

Evolutionary cores of domain co-occurrence networks [PDF]
BMC Evolutionary Biology, 2005 Abstract Background The modeling of complex systems, as disparate as the World Wide Web and the cellular metabolism, as networks has recently uncovered a set of generic organizing principles: Most of these systems are scale-free while at the same time modular, resulting in a hierarchical architecture. The

Co‐occurrence of browning and oligotrophication in a boreal stream network [PDF]
Limnology and Oceanography, 2022 AbstractThe relative supply of carbon (C), nitrogen (N), and phosphorus (P) to freshwater ecosystems is of fundamental importance to aquatic productivity, nutrient cycling, and food web dynamics. In northern landscapes, ongoing climate change, as well as legacies from atmospheric deposition, have the potential to drive changes in how these elements are

Earth microbial co-occurrence network reveals interconnection pattern across microbiomes
Microbiome, 2020 Background Microbial interactions shape the structure and function of microbial communities; microbial co-occurrence networks in specific environments have been widely developed to explore these complex systems, but their interconnection pattern across ...

Anaerobe-enriched gut microbiota predicts pro-inflammatory responses in pulmonary tuberculosis
EBioMedicine, 2021 Background: The relationship between tuberculosis (TB), one of the leading infectious causes of death worldwide, and the microbiome, which is critical for health, is poorly understood.
