"刻奇现象"是指人为地过多赋予事情或物件某种特殊意义的行为。随着数字化信息传播技术的日益发展,"刻奇现象"在体育新闻中时常发生。通过观察法、文献资料法对"刻奇现象"进行研究,指出"刻奇现象"在体育新闻中的三点表现,一是体育明星被媒体和公众过度关注,常被赋予过多意义;二是媒体肆意发布、公众热衷转发带有夸张、煽情等标题的文章;三是该现象可能以网络暴力及道德绑架的形式呈现。还从媒体、受众、社会三个层面对体育新闻中"刻奇现象"的成因进行分析,并归纳出体育新闻中"刻奇现象"的四点影响,即"刻奇现象"能在一定程度上丰富人们的精神生活;对体育运动的发展具有推动作用;常导致体育新闻事件出现误读情况,与媒体的宣传初衷相违背;容易加重网络暴力及道德绑架行为,从而破坏互联网舆论环境。这旨在引发人们对存在于社会方方面面的"刻奇现象"的关注与思考。

In recent years, thermochromic smart windows have played an important role in enhancing energy efficiency and contributing to carbon neutrality in building energy consumption. However, thermal-shielding smart windows with high visible light modulation and structural colors are rarely reported. This study focuses on the development of thermochromic smart windows utilizing poly（N-isopropylacrylamide）(PNIPAm)-based nanogels, which exhibit dynamic solar modulation and high visible light transmission without additional energy input. Unlike traditional electrochromic materials such as tungsten trioxide, these smart windows achieve structural color states through the self-assembly of nanogels, eliminating the need for inorganic materials. The fabricated hydrogel contains thermo-responsive poly（N-isopropylacrylamide-random-acrylic acid-random-N-tert-butyl acrylamide）P（NIPAm-r-AA-r-TBA）(PNTA) nanogels with tunable phase transition temperatures（Tp） that align with ambient *** smart windows demonstrate excellent stability over 100 heating-cooling cycles and significant temperature regulation,achieving an indoor temperature modulation of 10 °C and energy savings of 14.24 KJ m-3compared with normal windows. The production process is simple and scalable, making it feasible for industrial applications. Furthermore, these smart windows offer additional functionalities such as information encryption, adding value to their practical application.

软件缺陷预测研究中,研究人员通常使用有标记的数据进行预测模型的构建。但是在实际应用中往往会存在有标记样本不足的情况,为了应对这种状况,专家学者引入了半监督学习。尽管近年来不断有学者提出项目内的半监督缺陷预测方法,这些方法的预测准确度还有很大的提升空间。该文提出了一种新的半监督极限学习机软件缺陷预测方法,即基于改进SMOTE的半监督极限学习机方法。首先提出了一个改进的SMOTE采样方法来缓解类不平衡问题,其次使用了栈式去噪自动编码器来保留和获得更好的特征表示,最后为了提高模型的学习速率,获得更好的泛化性能,引入了极限学习机。通过在NASA和AEEEM数据集上的大量实验,结果表明该方法与基线方法相比获得了更好的预测性能。

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.
