Tail risk measures with application for mixtures of elliptical distributions

Autor: Pingyun Li, Chuancun Yin

Publikováno v: AIMS Mathematics, Vol 7, Iss 5, Pp 8802-8821 (2022)

In this paper we derive explicit formulas of tail conditional expectation (TCE) and tail variance (TV) for the class of location-scale mixtures of elliptical distributions, which includes the generalized hyper-elliptical (GHE) distribution. We also d

Sol–gel preparation of crystalline Ni12P5/N-doped carbon and amorphous Ni–P–C catalysts and their high catalytic performances toward hydrogenation reduction reaction of 4-nitrophenol

Autor: Han Wang, Haitao Ni, Pingyun Li, Shengxiang Jiang

Publikováno v: New Journal of Chemistry. 45:15801-15807

Sol–gel method was used to prepare Ni12P5/N-doped carbon and amorphous Ni–P–C materials where the dried gel precursors were heated under N2 atmosphere in a tube furnace. By using ethylene diamine tetraacetic acid (EDTA) as the chelating agent,
