Published in 2020 at "Acta Geodaetica et Geophysica"

DOI: 10.1007/s40328-020-00304-6

Abstract: A model describing the frequency distribution of geomagnetic field fluctuations has been developed, allowing a better understanding of the influence of the solar magnetic field on the geomagnetic variations. The constructed model is analogous to… read more here.

Published in 2021 at "Chemical Engineering Science"

DOI: 10.1016/j.ces.2021.116945

Abstract: Abstract As a classical example of granular flow, gravity-driven hopper flow has been studied for decades, but an in-depth understanding of its fluctuation is still lacking, especially at small-scale and short-term. In this experimental and… read more here.
