The games of three-dimensional life are the extension models of Conway’s Game of Life. Under the framework of symbolic dynamics, we undertake an analysis of the complexity of gliders in games of threedimensional life rules by the directed graph representation and transition matrix. More specifically, the gliders here are topologically mixing and possess positive topological entropy on their con...

Introduction: The heavyweight concretes have been widely used for constructing medical or industrial radiation facilities with photon sources. Materials and Methods: In this study, heavy concretes containing galena (PbS) and several borated minerals are proposed as suitable materials against photons. The shielding properties of 21 galena concretes containing seven borated minerals with three m...

In recent years, with the rapid development of coal-mining industry, output gangue has increased at a faster pace, while its utilization remains relatively low. The accumulation large amount brought about environmental problem. order to improve rate waste gangue, and solve secondary problems caused by pollution, this paper conducted research on an economic environmentally friendly gangue-based ...

A new and inexpensive technique for detecting self interacting dark matter in the form of small grains in bulk matter is proposed. Depending on the interactions with ordinary matter, dark matter grains in bulk matter may be isolated by using a centrifuge and using ordinary matter as a filter. The case of mirror matter interacting with ordinary matter via photon-mirror photon kinetic mixing prov...
