there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
We investigate one-dimensional three-body systems composed of two identical bosons and one imbalanced atom (impurity) with two-body zero-range interactions. For the case in absence interaction, we give a complete phase diagram number bound states whole region mass ratio via direct calculation Skornyakov-Ter-Martirosyan equations. demonstrate that other low-lying emerge when impurity particle is...
Multi-component coupling reaction (MCR) is a powerful synthetic tool for the synthesis of biologically active compounds. Development of such multi-component coupling reaction strategies in visible light has been of considerable interest, as they provide simple and rapid access to a large number of organic molecules through a sustainable path. An efficient and green protocol for the synthesis of...
