The species of the genera Nipponoserica Nomura, 1973 and Paraserica Reitter, 1896 from China are revised. The following eight new species are described from China: Paraserica camillerii Ahrens, Fabrizi, & Liu, sp. n., P. mupuensis Ahrens, Fabrizi, & Liu, sp. n., P. wangi Ahrens, Fabrizi, & Liu, sp. n., Nipponoserica alloshanghaiensis Ahrens, Fabrizi, & Liu, sp. n., N. anjiensis Ahrens, Fabrizi,...
The lacteus-, mycetophilus- and laspeyresiella-groups of the genus Apanteles Foerster (Hymenoptera, Braconidae, Microgastrinae) are newly recorded from China with eight new species being described, namely A. basicavus Liu & Chen, sp. n. of the lacteus-group; A. brevivena Liu & Chen, sp. n. and A. parapholetesor Liu & Chen, sp. n. of the mycetophilus-group; A. artustigma Liu & Chen, sp. n., A. h...
The following new taxa of Meconematini from Guangxi province were described: Sinothaumaspis damingshanicus Wang, Liu, Li gen. & sp. nov., Aphlugiolopsis punctipennis Wang, Liu, Li gen. & sp. nov., Eoxizicus (Eoxizicus) curvicercus Wang, Liu, Li sp. nov., Meconemopsis paraquadrinotata Wang, Liu, Li sp. nov., Neocrytopsis? unicolor Wang, Liu, Li sp. nov., Xiphidiopsis (Dinoxiphidiopsis) expressa ...
This article gives an introduction to arithmetic motivic integration in the context of p-adic integrals that arise in representation theory. A special case of the fundamental lemma is interpreted as an identity of Chow motives.
In this paper the exact determination of the distribution of stopping variable, the moment and risk of sequential estimator of the failure rate of exponential distribution, under convex boundary is obtained. The corresponding Poisson Process is used to derive the exact distribution of stopping variable of sequential estimator of the failure rate. In the end the exact values of mean and risk ...
Several sampling distribution properties of the estimator for Cpk are presented under the assumption that the data are normal, independent and identically distributed. In this paper using these assumptions, the expectation, variance and skewness are calculated by statistical methods, since the sampling distribution is weakly skewed, it is concluded that a symmetric interval estimator for Cpk mi...
the aim of this paper is to study distribution of ratios of generalized order statistics from pareto distribution. parameter estimation of pareto distribution based on generalized order statistics and ratios of them have been obtained. inferences using method of moments and unbiased estimator have been obtained to develop point estimations. consistency of unbiased estimator has been illustrate...
A review of the genus Pteranabropsis Gorochov is presented. Five new species are described, namely Pteranabropsis tenchongensis Wang, Liu, Li sp. nov., Pteranabropsis infuscatus Wang, Liu, Li sp. nov., Pteranabropsis karnyi Wang, Liu, Li sp. nov., Pteranabropsis parallelus Wang, Liu, Li sp. nov. and Pteranabropsis tibenensis Wang, Liu, Li sp. nov.. A key to the species of Pteranabropsis is prov...
