Pedigree transmission disequilibrium test for quantitative traits in farm animals

General pedigrees are very common in farm animals,and the recent availability of large panels of SNPs in domestic species has given new momentum to the search for the mutations underlying variation in quantitative traits.In this paper,we proposed a new transmission disequilibrium test approach,called the pedigree transmission disequilibrium test,which deals with general pedigrees and quantitative traits in farm animals.Compared with the existing pedigree disequilibrium test (PDT) and general linear model-based method QTDT,our approach performed better with higher power and lower type I error,especially in scenarios where the quantitative trait locus (QTL) effect was small.We also investigated the application of our approach in selective genotyping design.Our simulation studies indicated that it was plausible to implement a selective genotyping strategy in the proposed pedigree transmission disequilibrium test.We found that our approach performed equally well or better when only some proportion of the individuals in the two tails were genotyped compared with its performance when all the individuals in the pedigree were genotyped.     

变异理论与概念教学中正反例的开发策略

概念的例子分正例和反例两种,正例具有概念所有的相关属性,反例减少或增加了一条或多条概念的相关属性。以变异理论提出的几种变与不变的范式为方法论基础,提出概念正反例的三条开发策略:正例开发的策略是相关属性不变,无关属性要变化;反例的开发策略是相关属性要变化,无关属性不变;相互匹配的正反例的开发可以互为线索,相互启发。     

Spiritual Enlightenment From Language on English Learners

Language could be performed well with people who are familiar with the background and other factors of this language. As foreign language learners, performing well depends on knowledge of the attribute property of language and the post-natal education which plays a major role in language learning. Compared with the former one, post-natal education could be concerned by more and more learners. It is also an approach for English learners to know more about English and some relevant points.

XXXIX.—The Hippoboscidæ (Diptera) recorded from Ceylon

Summary

The most profitable ways of collecting chalcids are discussed, namely by sweeping, suction sampler, beating, pyrethrum spray, rearing, Malaise traps, yellow pan traps, suction traps, pitfall traps and extraction from leaf litter or grass tussocks. Methods of preserving chalcids are also outlined, with particular emphasis on storing all unmounted material dry rather than in alcohol. The techniques of sweeping, card mounting specimens and slide preparation are described in detail.

论证券自律规则的法律属性

证券自律规则法律属性的判断取决于证券自律管理权系公权力抑或私权利的认识。证券监管部门的审批不会使得自律规则成为规章,但经证券监管部门审批的规则具有了准行政规范性文件的属性,应经证券监管部门审批而未审批的证券自律规则不具有法律效力。无需审批的证券自律规则具有民事规则的属性,但实践中哪些自律规则需经审批还需进一步界定。

具有模糊联想神经网络的自组织模糊控制器

在分析了几种用神经网络实现的模糊控制器不足的基础上，提出一种用模糊联想记忆神经网络实现的自组织模糊控制器；该控制器由２个模糊联想记忆神经网络分别记忆校正规则表和修正控制规则表，并通过网络权值矩阵的在线修正完成控制规则的实时修正。模糊推理则由网络的自联想功能完成。
