    • Multiplex model of mental lexicon reveals explosive learning in humans 

      Stella, Massimo; Beckage, Nicole M.; Brede, Markus; De Domenico, Manlio (Nature Publishing Group, 2018-02-02)
      Word similarities affect language acquisition and use in a multi-relational way barely accounted for in the literature. We propose a multiplex network representation of this mental lexicon of word similarities as a natural ...

    • Extended bioreactor conditioning of mononuclear cell–seeded heart valve scaffolds 

      VeDepo, Mitchell; Buse, Eric; Quinn, Rachael; Hopkins, Richard; Converse, Gabriel (SAGE Publications, 2018-01)
