Comparing Models for Extracting the Backbone of Bipartite Projections

  title={Comparing Models for Extracting the Backbone of Bipartite Projections},
  author={Zachary P. Neal and R. Domagalski and Bruce Sahan},
Projections of bipartite or two-mode networks capture co-occurrences, and are used in diverse fields (e.g., ecology, economics, bibliometrics, politics) to represent unipartite networks that would otherwise be difficult or impossible to measure directly. A key challenge in analyzing such networks is determining whether an observed number of co-occurrences is significant. Several models now exist for doing so and thus for extracting the backbone of bipartite projections, but they have not been… Expand

Backbone: An R package for extracting the backbone of bipartite projections
The R package backbone for extracting the backbone of weighted bipartite projections is introduced, and bill sponsorship data from the 114th session of the United States Senate is used to demonstrate its functionality. Expand
GeneTonic: an R/Bioconductor package for streamlining the interpretation of RNA-seq data
Offering both bird’s-eye views of the components of transcriptome data analysis and the detailed inspection of single genes, individual signatures, and their relationships, GeneTonic aims at simplifying the process of interpretation of complex and compelling RNA-seq datasets for many researchers with different expertise profiles.

A sign of the times? Weak and strong polarization in the U.S. Congress, 1973-2016
It is found that both chambers exhibit both weak and strong polarization, that both forms are increasing, and that they are structured by political party affiliation, however, these trends are unrelated to which party holds the majority in a chamber. Expand

Gastrointestinal dysbiosis following diethylhexyl phthalate exposure in zebrafish (Danio rerio): Altered microbial diversity, functionality, and network connectivity.
Data suggest that the addition of DEHP in the diet may exacerbate microbial dysbiosis, a consequence that may explain in part its role as an obesogenic chemical. Expand
Legislators’ roll-call voting behavior increasingly corresponds to intervals in the political spectrum
An alternative, discrete, representation that replaces positions (points and distances) with niches (boxes and overlap) is proposed that is sufficient to represent the similarity of roll-call votes by U.S. senators in recent years. Expand
