• Efficiently mining rich subgraphs from vertex-attributed graphs

    March 9, 2023 by

    Riyad Hakim, Saeed Salem Abstract With the rapid collection of large network data such as biological networks and social networks, it has become very important to develop efficient techniques for network analysis. In many domains, additional attribute data can be associated with entities and relationships in the network, where the network data represents relationships among… Read more

  • Evolutionary dynamics of piRNA clusters in Drosophila

    February 27, 2023 by

    Filip Wierzbick, Robert Kofler, Sarah Signor Abstract Small RNAs produced from transposable element (TE)-rich sections of the genome, termed piRNA clusters, are a crucial component in the genomic defence against selfish DNA. In animals, it is thought the invasion of a TE is stopped when a copy of the TE inserts into a piRNA cluster,… Read more

  • Size constrains oxygen delivery capacity within but not between bumble bee castes in Bombus impatiens

    Rikki Walter, Joseph. P. Rinehart, Michael E. Dillon, and Kendra. J. Greenlee Abstract Bumble bees are eusocial, with distinct worker and queen castes that vary strikingly in size and life-history. The smaller workers rely on energetically-demanding foraging flights to collect resources for rearing brood. Queens can be 3 to 4 times larger than workers, flying… Read more
