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.

Effect of Mg-treatment on transformation of oxide inclusions in X80 pipeline steel

引用

Journal of Iron and Steel Research International 2024年第11期31卷 2802-2814页

作者： Ping Shen hao Zhang Kang Xu shuai Liu jin-xing Jiang Jian-xun Fu Center for Advanced Solidification Technology(CAST) State Key Laboratory of Advanced Special SteelShanghai UniversityShanghai200444China Nanjing Iron and Steel Co. Ltd.Nanjing210000JiangsuChina

In order to investigate the modification behavior and regularity of inclusions in X80 pipeline steel by Mg-treatment, the comparative industrial experiments of Mg-treatment and Ca-treatment in X80 pipeline steel were carried out. Mg and Ca were added to the steel in the form of cored wire after RH (Ruhrstahl-Hereaeus vacuum degassing) process. After adding Ca-containing cored wire, the inclusions were transformed into CaO–Al_(2)O_(3) in the steel. With the progress of smelting, the cleanliness of molten steel became worse, and the equivalent diameter of inclusions was at a higher level. Mg-treatment had a good effect on the modification of inclusions. After Mg-containing cored wire was added to the steel, Al_(2)O_(3) and CaO–Al_(2)O_(3) in the steel were transformed into MgO, MgO·Al_(2)O_(3), and CaO–MgO–Al_(2)O_(3) inclusions, which were basically spherical. The initial precipitated MgO became the core of other inclusions in the steel, which promotes the precipitation of MgO·Al_(2)O_(3). After Mg-treatment, almost no unmodified calcium aluminate inclusions existed in the hot rolled plate, and the cleanliness of the steel was improved. The effect of Ca and Mg on the transformation of inclusions in pipeline steel was studied by thermodynamic calculation, the result of which is consistent with the experimental results.

Robust detection algorithm with triple constraints for cooperative target based on spectral residual

引用

Journal of Systems Engineering and Electronics 2017年第4期28卷 654-660页

作者： shuai hao Yongmei Cheng Xu Ma School of Electrical and Control Engineering Xi'an University of Science and Technology College of Automation Northwestern Polytechnical University

The accurate detection of cooperative targets plays a key and foundational role in unmanned aerial vehicle (UAV) landing autonomously. The standard method based on fixed threshold is too susceptible to both illumination variations and interference. To overcome issues above, a robust detection algorithm with triple constraints for cooperative targets based on spectral residual (TCSR) is proposed. Firstly, by designing an asymmetric cooperative target, which comprises red background, green H and triangle target, the captured original image is converted into a Lab color space, whose saliency map is yielded by constructing the spectral residual. Then, the triple constraints are developed according to the prior knowledge of the cooperative target. Finally, the salient region in saliency map is considered as the cooperative target, and it meets the triple constraints. Experimental results in complex environments show that the proposed TCSR outperforms the standard methods in higher detection accuracy and lower false alarm rate.

采用基于密度泛函理论的第一性原理,计算了本征CsPbI_(3)和Mn、Zn、Sn掺杂体系的形成能、电子结构和光学性质.研究结果表明:Mn、Zn、Sn的掺入减小了材料晶格常数,Mn原子掺入CsPbI_(3)晶体结构使得体系的磁矩由0变为5.00μ_(B),丰富了材料磁性.与Zn掺杂体系相比,Mn、Sn掺杂体系更为稳定.Mn掺杂体系增大了材料带隙,Zn、Sn的掺入使材料带隙分别减小了30.2%和16.2%,有利于电子极化跃迁,但Zn掺入使CsPbI_(3)材料转变为间接带隙半导体.在可见光区域中Mn、Zn、Sn掺杂体均表现出优异的光学性能,Sn掺杂体系效果最佳.这些研究结果为实验方面CsPbI_(3)材料的掺杂改性提供了数据支持,有利于CsPbI_(3)钙钛矿在光电领域的应用.
