Published in 2017 at "Quarterly Journal of the Royal Meteorological Society"

DOI: 10.1002/qj.2989

Abstract: Extratropical cyclones experience vastly different genesis conditions at the first point of their tracks. A novel method is introduced to characterize this variability and classify genesis events by computing 30 diagnostic variables that describe the… read more here.

Published in 2018 at "Multivariate Behavioral Research"

DOI: 10.1080/00273171.2018.1471975

Abstract: ABSTRACT In the study, extending from the cross-lagged panel model (CLPM) and the 2-2-1 cross-sectional multilevel mediation model, we proposed a three-level longitudinal mediation model to evaluate the causal process among variables at different levels… read more here.

Published in 2022 at "Connection Science"

DOI: 10.1080/09540091.2022.2077312

Abstract: In multi-objective bilevel optimisation problems, the upper-level performance of different lower-level optimal solutions may be very different, even though they belong to the same lower-level problem. It may lead to poor optimisation results. Therefore, the… read more here.
