The objective of this work is a study of the structural properties (lattice parameters, total energy, bulk modulus) and electronic properties (band structure, density of states) of rare earth monochalcogenides LaX (X=Se, ...

The mechanical properties of materials are determined by the interactions between defects found in the crystal. In a bicrystal of bimaterials, the result forces exercising on the matrix dislocation near and parallel to an ...

Recent developments in radiotherapy techniques, particularly VMAT technique is a tool of choice in the treatment of tumors with complex shapes such as head and neck cancers. Patients with head and neck cancer are prone ...

The analytical methods based on X-ray fluorescence have a great importance for a number of practical applications in a variety of fields including atomic physics, X-ray fluorescence surface chemical analysis, medical ...

One of the most fundamental questions we can ask about a given gauge theory is its phase diagram. We present Monte Carlo simulations, for a simple three matrix model that exhibits an exotic phase transition. we focus on ...

In this work we calculate photoionization X-ray cross-sections of K-shell vacancies in S at incident photon energy of 59.6 keV using the Dirac-Fock method and the MCDFGME (Multi Configuration Dirac Fock and General Matrix ...

The origin of ultra-high-energy cosmic rays is one of the most enigmatic questions in modern physics. The study of a such high-energy particles is a new and active research area where scientists wish to find the still-unknown ...
