The ballistic conduction through narrow constrictions connecting charge reservoirs exhibits conductance quantization effects. Since the quantum of G 0 = 2 e / h ${G_0} {\rm{\;}}2{{\rm{e}}^2}/h$ is only related to fundamental constants nature, these effects might allow implementation a standard resistance, fulfilling requirements 2019 revised International System Units. Moreover, this would be a...

so far the static properties of hadrons have been introduced in various models. the static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. in this work we have introduced the hypercentral constituent quark and isospin dependent potentials. here constituent quarks interact with each other via a potential in which we have ta...

the n-(2-benzoyl-phenyl) oxalyl derivatives are important models for studying of three-centered intramolecular hydrogen bonding in organic molecules. the quantum theoretical calculations for two crystal structures of n-(2-benzoyl-phenyl) oxalyl (compounds i and ii) were performed by density functional theory (b3lyp method and 6-311+g* basis set). from the optimized structures, geometric paramet...
