Randomness

  1. Integrated ACD models can imply infinite-mean durations
    Asymptotic theory for integrated autoregressive conditional duration models reveals infinite-mean trading intervals in cryptocurrency ETFs, requiring new inference methods.
  2. Bio-inspired Voronoi tubes improved energy absorption
    Bio-inspired Voronoi tubular structures replicate luffa sponge architecture for enhanced energy absorption. Parametric design optimization increases specific energy absorption by up to 78%.
