To develop new energy enhancement energetic materials with great combustion performance and thermal stability, two kinds of ternary thermite, Al/Fe2O3/CuO and Al/Fe2O3/Bi2O3, were prepared and analyzed via mechanical ball milling. The samples were ch

We study the gap sequence of totally disconnected McMullen sets. Our result shows that if every horizontal line in the McMullen set is nonempty, then the gap sequence is unrelated to the box dimension. This implies that in such situations, the separa

We obtain the Assouad dimensions of Moran sets under suitable condition. Using the homogeneous set introduced in [J. Math. Anal. Appl., 2015, 432: 888–917], we also study the Assouad dimensions of Cantor-like sets.

This paper studies the self-similar fractals with overlaps from an algorithmic point of view. A decidable problem is a question such that there is an algorithm to answer “yes” or “no” to the question for every possible input. For a classical

We study the boundary properties of u ( x , y ) = K y ∗ μ ( x ) , defined on the half-space R ∗ + × R N by the convolution of an approximate identity K y ( ⋅ ) ( y > 0 ) and the Ahlfors–David singular s -measure μ on R N . The Poisson and

Hierarchical massive quadruple systems are ideal laboratories for examining the theories of star formation, dynamical evolution, and stellar evolution. The successive mergers of hierarchical quadruple systems might explain the mass gap between neutro

Suppose compact sets E and F are quasi uniformly disconnected and quasi Ahlfors-David regular. This paper proves that E and F are quasi-Lipschitz equivalent if and only if they have the same Hausdorff dimension.
