Semi-parametric regression estimation of the tail index [PDF]
, 2018 Consider a distribution F with regularly varying tails of index −α. An estimation strategy for α, exploiting the relation between the behavior of the tail at infinity and of the characteristic function at the origin, is proposed.

Plant Secondary Metabolites as Defense Tools against Herbivores for Sustainable Crop Protection
International Journal of Molecular Sciences, 2022 Plants have evolved several adaptive strategies through physiological changes in response to herbivore attacks. Plant secondary metabolites (PSMs) are synthesized to provide defensive functions and regulate defense signaling pathways to safeguard plants ...
