We,in this paper,investigate two-sample quantile difference by empirical likelihood method when the responses with high-dimensional covariates of the two populations are missing at random.In particular,based on sufficient dimension reduction technique,we
小牛壮壮最近在家闲着没事干,听说狐狸老板想种一批树苗,正在四处找人承包这项工程,壮壮得知后,便去把活儿揽了下来.rn壮壮和狐狸老板约定,壮壮每栽一棵树苗,狐狸老板就要付给他5元的工钱.壮壮心想:人家都说你是狡猾的老板,我可不怕,只要记住我栽一棵树苗得5元钱就行了.于是,壮壮使出浑身力气,拼命地干活,经过一天的辛勤劳动,壮壮终于按狐狸老板的要求栽完了树苗.
今天是雏鹰假日小队的活动日,实验小学的队员们准备走上街为民服务.rn第一小队的队长要求本队队员戴袖章,男生和女生还要区分开,男生都戴黄色的,女生都戴红色的.rn整队出发前要清点人数,这时出现了一组有趣的数.rn在每个男孩看来,不算自己的袖章,黄色袖章和红色袖章一样多.
This paper is concerned with the following Chern Simons Schr(o)dinger equation-Δu + V(|x|)u +(∫∞|x|h(s)/su2(s)ds + h2(|x|)/|x|2)u=a(|x|)f(u) in R2,where h(s) =∫e0l/2u2(l)dl,V,a :R+ → R are radially symmetric potentials and the nonlinearity f :R → R is of
有的小朋友在解决关于等号问题的时候,经常出错,到底是怎么回事呢?今天,我们就一起走进数学“小诊所”,看看都有哪些“病人”!
The purpose of the present paper is to deliberate *-conformal Yamabe soliton,whose potential vector field is torse-forming on Kenmotsu manifold.Here,we have shown the nature of the soliton and find the scalar curvature when the manifold admitting *-confor
Let T be a strongly singular Calderón Zygmund operator and b ∈ Lloc(Rn).This article finds out a class of non-trivial subspaces BMOω,p,u(Rn) of BMO(Rn) for certain ω ∈ A1,0 ＜ p ≤ 1 and 1 ＜ u ≤ ∞,such that the commutator[b,T]is bounded from weighted Hardy
Let K be a genus g alternating knot with Alexander polynomial ΔK(T) =Σgi=-gaiTi.We show that if |ag| =|ag-1|,then K is the torus knot T2g+1,±2.This is a special case of the Fox Trapezoidal Conjecture.The proof uses Ozsváth and Szab(o)\'s work on alterna
