in this study the operations of melting of au15ag40 nanoalloy have been studied using the molecular dynamic simulations through the gupta multiparticle potential and the nonergodicity of simulations is eliminated by the multiple histogram method. the melting characteristics are determined by the analysis of variations in the potential energy. the calculations indicate that the melting of au15ag...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

We present a fully analytical description of many-body localization (MBL) transition in microscopically defined model. Its Hamiltonian is the sum one- and two-body operators, where both contributions obey maximum-entropy principle have no symmetries except Hermiticity (not even particle number conservation). These two criteria paraphrase that our system variant Sachdev-Ye-Kitaev will demonstrat...

Heat transfer by electromagnetic radiation is one of the common methods of energy transfer between objects. Using the fluctuation-dissipation theorem, we have studied the effect of particle arrangement in the transmission of radiative heat in many-body systems. In order to show the effect of the structure morphology on the collective properties, the radiative heat transfer is studied and the re...
