简介：Paradox(悖论）一词来自希腊语“Para-dokein”，意思是“多想一想”，现在paradox可指导致矛盾的命题，如果承认此命题为真，经过一系列正确的推理，却又得出它是假的，如果承认它是假的，经过一系列正确的推理，却又得出它是真的，古今中外有不少著名的悖论，

简介：为了解决用户体验中的“过度包装”问题，亚马逊引进一款新纸箱制造机。它不仅可以根据货品大小的容量来制定纸箱的最小尺寸，还可以开启自己的生产线进行匹配生产。虽然这个项目暂时处在试验阶段，但其可为公司节省40％的成本。这就意味着如果试验项目顺利的话，对原有纸箱市场的供应链条将会带来巨大的冲击。

简介：根据拟南芥的MIKC型MADS—box蛋白序列构建HMM（hiddenmarkovmodel）模型，在大豆基因组中确定了57个MIKC型MADS-box同源基因。分子进化树分析表明，57个大豆MIKC型MADS-box基因分为14个亚类，而MIKC^＋型基因又分为两个进化支。控制花形态建成的ABCDE同源异型基因（如AP1，AG，AP3和PI等）和重要的控制开花时间的基因（如SVP和SOCl）在大豆基因组中表现出多拷贝的特征。MEME和SMART分析表明，大豆和拟南芥MIKC型MADS—box基因具有保守的MADS和K-box基序，还有一些亚类具有特异的基序。MIKC型MADS—box基因结构较为保守，多数基因具有7～8个外显子。本研究得到的MIKC型MADS—box基因为下一步研究大豆花形态建成和开花时间调控的分子机制提供了重要参考依据。
