Analysis of danger source of mine gas explosion based on Petri nets
Gong-kuang zidonghua, 2015 By analyzing danger source associated with mine gas explosion, the evolution model GEFRPN of gas explosion based on Petri nets was constructed combining Petri nets theory and the evolution of gas explosion, and the conclusion was obtained: from reasoning

Explosions and Outflows during Galaxy Formation [PDF]
, 2001 We consider an explosion at the center of a halo which forms at the intersection of filaments inside a cosmological pancake, a convenient test-bed model for galaxy formation. ASPH/P3M simulations reveal that such explosions are anisotropic.

Ultrafaint Dwarfs - Star Formation and Chemical Evolution in the Smallest Galaxies [PDF]
, 2014 In earlier work we showed that a dark matter halo with a virial mass of $10^7$ M$_\odot$ can retain a large percentage of its baryons in the face of the pre-ionization phase and supernova explosion from a 25$M_\odot$ star.
