1肺栓塞的超声心动图诊断显示文摘目的探讨经胸彩色多普勒超声心动图肺栓塞的诊断价值。方法利用二维超声(2DE)、脉冲多普勒(PW)和彩色多普勒血流显像(CDFI)检测肺动脉、心脏和下腔静脉等。结果超声心动图肺栓塞的直接征象可做诊断,间接征象可做提示。结论超声心动图简便易行、费用低,可筛检、重复检测肺动脉压。宋钧 袁静 杨文鹏 许惠敏 Henryk Siniawski 2007中国心血管病研究2007,5,6:7
2Approximative compactness and continuity of metric projector in Banach spaces and applications显示文摘First we prove that the approximative compactness of a nonempty set C in a normed linear space can be reformulated equivalently in another way.It is known that if C is a semi-Chebyshev closed and approximately compact set in a Banach space X,then the metric projectorπC from X onto C is continuous.Under the assumption that X is midpoint locally uniformly rotund,we prove that the approximative compactness of C is also necessary for the continuity of the projectorπC by the method of geometry of Banach spaces.Using this general result we find some necessary and sufficient conditions for T to have a continuous Moore-Penrose metric generalized inverse T^+,where T is a bounded linear operator from an approximative compact and a rotund Banach space X into a midpoint locally uniformly rotund Banach space Y.HUDZIK Henryk KOWALEWSKI Wojciech WISLA Marek 2008Science China Mathematics2008,51,2:5
3Back to Basics:Are Begomoviruses Whitefly Pathogens?显示文摘Begomoviruses and whiteflies have interacted for geological times.An assumed long-lasting virus-vector intimate relationship of this magnitude implies that the partners have developed co-evolutionary mechanisms that insure on one hand the survival and the efficient transmission of the virus,and on the other hand the safeguard of the insect host from possible deleterious effects of the virus.Several studies have indicated that viruses belonging to the Tomato yellow leaf curl virus(TYLCVs)family from China,Israel and Italy are reminiscent of insect pathogens.TYLCVs like all begomoviruses are transmitted in a circulative manner by the whitefly Bemisia tabaci.The survival of the virus in the haemolymph of B.tabaci is ensured by a GroEL homologue produced by a whitefly secondary endosymbiont.Following acquisition and transfer to non-host plants,the virus may remain associated with the insect for its entire 4-5 wk-long adult life.During this period,the ability of the insects to inoculate plants steadily decreased,but did not disappear.The long-term presence of TYLCVs in B.tabaci was associated with a decrease in the insect longevity and fertility.Viral DNA was transmitted to progeny,but seldom infectivity.TYLCV transcripts were found associated with the insects,raising the possibility of replication and expression in the vector.TYLCVs may spread amidst whiteflies during copulation.Functional genomics tools such as microarrays,deep sequencing,quantitative PCR and gene silencing allow revisiting the proposition that TYLCVs have retained,or acquired,some characteristics of an insect pathogen.Henryk Czosnek Murad Ghanim 2012Journal of Integrative Agriculture2012,11,2:2
4利用化学键方法寻找新型光学晶体(英文)显示文摘利用化学键的观点定量地研究了一些具有各种晶体结构实用材料的介电性质。采用已建立的化学键方法 ,分析了这些晶体的介电性质与其组成化学键之间的关系。更进一步 ,基于晶体的化学键方法提出了一个组合方法用于定量确定具有相似晶体结构材料的介电性质。从目前的工作中可以推导出光学晶体非线性起源的结构信息 ,因此可以在一定程度上帮助人们开展非线性光学晶体工程的研究工作。薛冬峰 Betzler Klaus Hesse Hartmut Kitamura Kenji Ratajczak Henryk 王继扬 2004人工晶体学报2004,33,4:2

6Bemisia tabaci Biotype Dynamics and Resistance to Insecticides in Israel During the Years 2008-2010显示文摘The sweetpotato whitefly Bemisia tabaci(Hemiptera:Aleyrodidae)is an extremely polyphagous insect pest that causes significant crop losses in Israel and worldwide.B.tabaci is a species complex of which the B and Q biotypes are the most widespread and damaging worldwide.The change in biotype composition and resistance to insecticide in Israel was monitored during the years 2008-2010 to identify patterns in population dynamics that can be correlated with resistance outbreaks.The results show that B biotype populations dominate crops grown in open fields,while Q biotype populations gradually dominate crops grown in protected conditions such as greenhouses and nethouses,where resistance outbreaks usually develop after several insecticide applications.While in previous years,Q biotype populations were widely detected in many regions in Israel,significant domination of the B biotype across populations collected was observed during the year 2010,indicating the instability of the B.tabaci population from one year to another.Reasons for the changing dynamics and the shift in the relative abundance of B.tabaci biotype,and their resistance status,are discussed.Svetlana Kontsedalov Fauzi Abu-Moch Galina Lebedev Henryk Czosnek A Rami Horowitz Murad Ghanim 2012Journal of Integrative Agriculture2012,11,2:2

8Continuous Homogeneous Selections of Set-Valued Metric Generalized Inverses of Linear Operators in Banach Spaces显示文摘In this paper,continuous homogeneous selections for the set-valued metric generalized inverses T of linear operators T in Banach spaces are investigated by means of the methods of geometry of Banach spaces.Necessary and sufficient conditions for bounded linear operators T to have continuous homogeneous selections for the set-valued metric generalized inverses T are given.The results are an answer to the problem posed by Nashed and Votruba.Hai Feng MA Henryk HUDZIK Wen WANG 2012Acta Mathematica Sinica,English Series2012,28,1:2
