We have previously developed a combined signal/variance distribution model that accounts for the particular statistical properties of datasets generated on the Applied Biosystems AB1700 transcriptome system. Here we show that this model can be efficiently used to generate synthetic datasets with statistical properties virtually identical to those of the actual data by aid of the JAVA application *** creator 1.0 that we have developed. The fundamentally different structure of AB1700 transcriptome profiles requires re-evaluation, adaptation, or even redevelopment of many of the standard microarray analysis methods in order to avoid misinterpretation of the data on the one hand, and to draw full benefit from their increased specificity and sensitivity on the other hand. Our composite data model and the *** creator 1.0 application thereby not only present proof of the correctness of our parameter estimation, but also provide a tool for the generation of synthetic test data that will be useful for further development and testing of analysis methods.

欧盟不是一个像联合国一样的国际组织,也不是一个为了取代国家政府的“政府”。欧盟对于“组织”更为强势而在“政府”面前却有无法弥补的劣势。它的作用体现在支撑欧盟成员国之间的共同行动比各自为战的单独行动更为高效。可以说欧盟是独一无二的。欧盟是一个由各国政府共同建立,在某些特定领域达成共识并共同行动的国际组织。在这些特定领域中,最好的政治理念是欧盟成员国之间合作共赢,而非单干。中国外交政策的原则是致力于促进世界和平与发展、国际合作。欧盟一直是中国在各领域良好的合作伙伴:如政治领域、经济领域、文化领域。中欧双方共同努力构建起来的联系与合作日益亲密,迅猛的发展势头令人无法想象。中国、欧盟两大经济体经济增长举世瞩目。中国正史无前例的在欧洲布局投资,同时欧洲各国也在紧密规划与中国的合作。本文论点是阐述欧盟中国之间合作潜力巨大。本文着力分析了 21世纪全球政治、经济格局之现状,并预测了未来战略合作伙伴关系。我们看到越来越多的项目如雨后春笋般在两个合作伙伴之间生根发芽,这种基于政治、经济、文化构建起的友谊牢不可破。对于中欧伙伴关系中出现的一般问题,处理方法是改变视角、审视范围与合作规模。中国与欧盟的战略伙伴关系的观点存在不同:中国强调的是综合、整体和长远的发展构架才能维持稳定和健康的双边关系,而欧盟则更看重的实质性的进展与具体的结果。其结论是:一种伙伴关系,两种处理方法。

Studies on high-throughput global gene expression using microarray technology have generated ever larger amounts of systematic transcriptome data. A major challenge in exploiting these heterogeneous datasets is how to normalize the expression profiles by inter-assay methods. Different non-linear and linear normalization methods have been developed, which essentially rely on the hypothesis that the true or perceived logarithmic fold-change distributions between two different assays are symmetric in nature. However, asymmetric gene expression changes are frequently observed, leading to suboptimal normalization results and in consequence potentially to thousands of false calls. Therefore, we have specifically investigated asymmetric comparative transcriptome profiles and developed the normalization using weighted negative second order exponential error functions （NeONORM） for robust and global inter-assay normalization. NeONORM efficiently damps true gene regulatory events in order to minimize their misleading impact on the norrealization process. We evaluated NeONORM＇s applicability using artificial and true experimental datasets, both of which demonstrated that NeONORM could be systematically applied to inter-assay and inter-condition comparisons.
