Figure three is a schematic diagram of a helium atom in its lowest energy state. Two protons are present in the nucleus of all helium atoms. In the most common variety of helium, the nucleus also contains two neutrons, which have nearly the same mass as the proton but carry no charge. ...

Atomic Structure refers to the fundamental components of matter, namely atoms, which consist of a nucleus and orbiting electrons. The nucleus, acting as the center of an atom, is positively charged and has a much greater mass than the negatively charged electrons. Atoms are electrically neutral ...
Physical boundaries are provided by the maximum values of Al and Td (blue boundaries in Fig. 6b, c). Td is limited by the temper diagram of cold work steel AISI 420 (X42Cr13, 1.2083). To avoid tempering of the substrate, the maximum Td should be lower than 450 °C. Al is ...

Section “Whale Optimization Algorithm based on atom-like structure differential evolution” presents the content of the WOAAD algorithm. Section “Time complexity analysis of WOAAD” analyzes the time complexity of the WOAAD algorithm. Section "Convergence analysis of WOAAD" discusses the convergence ...
The connection to the theory of particle self-assembly is discussed. We apply the results to several physical systems. We present the phase diagram for patchy particles described by the Kern-Frenkel potential. We show that the Curie-Weiss model with molecule structures exhibits a first-order ...
