Si p^+n junction diodes operating in the mode of avalanche breakdown are capable of emitting light in the visible range of 400-900 nm. In this study, to realize the switching speed in the GHz range, we present a transient model to shorten the carrier lifetime in the high electric field region by accumulating carriers in both p and n type regions. We also verify the optoelectronic characteristics by disclosing the related physical mechanisms behind the light emission phenomena. The emission of visible light by a monolithically integrated Si diode under the reverse bias is also discussed. The light is emitted as spatial sources by the defects located at the p-n junction of the reverse-biased diode. The influence of the defects on the electrical behavior is manifested as a current-dependent electroluminescence.

Objective： To investigate the expressions and correlations of Pin1, β-catenin and cyclin D1 in elderly lung carcinomas. Methods： The expressions of Pin1, β-catenin and cyclin D1 were examined in the specimens of 92 elderly lung carcinomas and 10 normal lung tissues by immunohistochemistry and explored the relationship between the expression levels and clinicopathological factors. Results：（1） The overexpression of Pin1 and cyclin D1 in lung carcinomas was 46 （50%） cases and 60 （65.22%） cases respectively and 56 （60.82%） cases showed positive immunoreactivity for 13-catenin in the nuclear and （or） cytoplasmic fraction in tumor tissues. In normal tissue, the expressions of Pin1 and cyclin D1 were negative, the expression of β-catenin was lied in cell membrane. （2） In lung carcinomas the expressions of Pin1, β-catenin and cyclin D1 correlated with tumor differentiation （P 〈 0.05）. The pesitive expression rate and intensity of Pin1 correlated with tumor stage （P = 0.032） and lymph node positive disease （P = 0.041）. The expression of β-catenin correlated with lymph node positive disease （P = 0.012）. （3） High expression levels of Pin1 correlated with aberrant I]-catenin expression （P = 0.000） but did not show a correlation with cyclin D1 （P = 0.157）. Conclusion： In elderly lung carcinomas, the positive expression of Pin1 causes abnormal accumulation of β-catenin and actives its target gene, however, this target gene was not cyclin DI. The detection of Pin1 expression had some clinical significance in estimating prognosis of elderly patient with lung carcinomas.

巴列维王朝是现代伊朗的起点。为抵御外敌和实现富国强兵,国王礼萨·汗开启了伊朗的现代化进程,并将波斯化运动作为现代民族国家构建的手段,系统改造阿塞拜疆等少数民族。但是礼萨·汗推行的波斯化运动造成了伊朗国内波斯民族同阿塞拜疆等民族的对立,激发了伊朗的阿塞拜疆民族主义。由于这一时期伊朗仍然积贫积弱,在国家主权甚至内政上并不能完全独立自主。在民族政策上,伊朗国王也不是伊朗现代民族国家建构的唯一决定性因素。随着第二次世界大战的爆发,苏联为攫取利益,选择支持伊朗的阿塞拜疆人对抗中央政府,这让伊朗的阿塞拜疆民族主义得以在苏联保护下兴起,并进而建立阿塞拜疆民主共和国。尽管这一尝试最终因苏联的政策变化归于失败,但它为伊朗的阿塞拜疆民族主义复兴埋下了种子,民族利益受到严重侵害的伊朗阿塞拜疆成了伊斯兰革命的先驱,并最终推翻了巴列维王朝。

伊拉克库尔德人寻求自治甚至独立的渴望从未泯灭。2014年,极端恐怖组织“伊斯兰国”的兴起给伊拉克库尔德人寻求独立提供了机会。库尔德人依赖海湾战争后同美国建立起的特殊关系,借助高级官员访问等机会发起对美国的游说,试图说服美国支持库尔德的独立公投。库尔德游说在美国国会引起很大反响,激发了库尔德、伊拉克政府、美国国会与包括白宫、国务院和国防部在内的美国行政部门之间的多重博弈。由于库尔德的独立公投严重违背美国的反恐优先和一个伊拉克的政策,且库尔德独立远未提到美国中东政策的议程上来,库尔德独立公投在美伊的联合反对下归于失败。在打击“伊斯兰国”取得胜利后,库尔德地区政府和伊拉克直接对话的结果,以及美国对时局的评估将决定伊拉克库尔德人的未来。
