Using a new and elegant reduction approach we derive a lower bound of quantum complexity for the approximation of imbeddings from anisotropic Sobolev classes B(W([0,l])) to anisotropic Sobolev space W([0,1.) for all 1.p,q≤∞. When p≥q this bound is *** this case the quantum algorithms are not significantly better than the classical deterministic or randomized *** p≥q we conjecture that quantum algorithms bring speed-up over the classical deterministic and randomized *** conjecture was confirmed in the situation s=0.

以71.名流动和城市儿童为被试,采用问卷调查法,考察了流动儿童的幸福感、安全感特点及其与社会排斥的关系。结果发现:(1.幸福感方面,五年级流动儿童得分显著低于城市儿童,初中二年级两类被试没有显著差异;(2)安全感方面,五年级和初中二年级流动儿童得分均显著低于城市被试;(3)流动儿童知觉到的学校社会关系排斥与其幸福感、安全感得分均存在显著相关;(4)安全感在社会排斥与幸福感的关系中起着完全中介作用,即社会排斥通过安全感对流动儿童的幸福感产生影响。

Based on the theory of non-convex interval goal programming and the discrete resources ideology,this paper constructs three basic storage resources allocation models,to illustrate the relationship between the aggregate requirement and the gross capability of storage in a group *** results for the oil country tubular goods(OCTG) of 1. subcompanies of a group oil enterprise, verified the scientificity and feasibility of the *** three models include:under the established demand,the problem-solving model of the best capability utilization,the decreased sensitivity analysis interval model of the best aggregate capability,and the interval optimization model of the external utilization efficiency of remaining capability.

In view of some current self-help websites system have fixed template. Users have little independent selective in the process of building web site. This paper puts forward customizable dynamic web site management system which adopts Browser/Server structure model. Using the JSP technology, make all parts of the website division independent. In addition, we also use AJAX technology to make each module of website in drag, thus enhancing the template can be customized greatly.

浅沟侵蚀是东北漫岗黑土区农耕地上常见的水蚀类型,往往对坡耕地造成严重的破坏。2005年春季,通过对两个小流域浅沟侵蚀的调查测量,发现该区浅沟侵蚀相当严重,两流域分别形成浅沟1.条、1.条,浅沟总长度分别达3 269 m、2 1.6 m,浅沟密度分别为908 m/km2、766 m/km2,侵蚀深度分别为0.1. mm、0.1. mm,侵蚀模数分别达1.1.8 t/km2、1.3.6 t/km2。2005年春季两流域浅沟侵蚀期的径流深分别是6.8 mm、7.7 mm。分析表明,研究区在春季表层土壤解冻、地表裸露和存在季节性冻土层的条件下,春季融雪及强降水易造成强烈的浅沟侵蚀。在分布上,浅沟一般位于坡面的中下部,而且多发育在瓦背状坡面的集流水路上。另外,耕作措施对浅沟的形成和发展也有重要影响。

In our previous study,menstrual-like changes in mouse were provoked through the pharmacologic withdrawal of progesterone with mifepristone following induction of decidualization. However,mouse is not a natural menstruation animal,and the menstruation model using external stimuli may not truly reflect the occurrence and development of the human menstrual ***,we established a model of menstruation based on human endometrial *** this model, human endometrial tissues were transplanted subcutaneously into SCID mice that were ovarectomized and supplemented with estrogen and progestogen by silastic implants with a scheme imitating the endocrinological milieu of human menstrual ***,hormone levels,and expression of vimentin and cytokeratin markers were evaluated to confirm the menstrual-like changes in this *** 28 days of hormone treatment,transplanted human endometrium survived and underwent proliferation, differentiation and disintegration,similar to human endometrium in *** CD45+ cells showed a peak of increase 28 days *** days after progesterone withdrawal,mouse CD45+ cells increased rapidly in number and were significantly greater than human CD45+ cell *** CD31. blood vascular-like structures were detected in both transplanted and host *** progesterone withdrawal,the expression levels of matrix metalloproteinases(MMP) 1.2,and 9 were *** summary,we successfully established a human endometrial xenotransplantation model in SCID mice,based on the results of menstrual-like changes in which MMP-1.2 and 9 are *** showed that leukocytes are originated from in situ proliferation in human xenografts and involved in the occurrence of *** model will help to further understand the occurrence,growth,and differentiation of the endometrium and the underlying mechanisms of menstruation.
