Magnetostructural stabilities, mechanical behaviors and electronic structures of various phases of manganese tetraboride (MnB4) have been investigated systematically by density functional theory (DFT) based first-principles methods.It is found that MnB4 undergoes temperature-induced phase transitions from the nonmagnetic (NM) monoclinic mP20 struct
Two types of variability are discernible in the ocean: a response to the atmospheric forcing and the so-called internal/intrinsic ocean variability, which is associated with internal instabilities, nonlinearities, and the interactions between processes at different scales.Producing an ensemble of 20 multiyear ocean simulations of the Mediterranean
Abstract Whiteboard animations have become very popular in recent years.They are mainly used in distance education, where learners can acquire knowledge individually and without the help of a teacher.However, there is little empirical evidence on how whiteboard animations should be designed to achieve learning-enhancing effects.Since the presentati

In this study, we investigate the possibility to trap an ion particle in a non-uniform electrostatic field generated by two ionic rings, with the aim to obtain and verify general results regarding our proposition.To develop the equation of motion, we first derive the electric field generated by each ring, based on the Backpacks multipole expansion
