Paclitaxel(taxol)stands out as a tetracyclic diterpenoid natural product derived from the endangered plant *** as a pivotal broad-spectrum anticancer drug,it has garnered widespread attention due to its low yield,intricate structure,unique anticancer mechanism,and remarkable efficacy(tong et al.,2021).Although chemists achieved the total synthesis of paclitaxel 30 years ago,after decades of research,the natural biosynthetic pathway for its production remains an enigma(Ajikumar et al.,2010;Malci et al.,2023).A recent breakthrough,published in Molecular Plant by Alisdair ***'s team,unveils a minimal gene set of 18 genes required for paclitaxel biosynthesis(Zhang et al.,2023),representing a significant mark toward unraveling the entire biosynthetic pathway and enhancing paclitaxel production efficiency.

the use of lead, some of which is characterized by a highly radiogenic signature, sharply distinguishes Bronze Age China from the rest of Eurasia. Scholars have long hypothesized that silver can offer an independent proxy to characterize lead minerals. the summary of silver distribution associated with Shang and Western Zhou bronzes in this paper reveals an important difference between the south(Sanxingdui, Hanzhong, Jinsha, Panlongcheng, Xin’gan) and the Central Plains. Correlating silver with lead content as well as with the isotopic signature indicates that south China and the Central Plains had different lead sources during the late Shang period, and also that the highly radiogenic and common lead used at Anyang come from geochemical environments which cannot be distinguished by the level of silver.

本文利用2000~2013年中国工业企业数据库与海关贸易数据库的合并数据测度了企业出口国内增加值率,在此基础上研究双边外交关系发展对中国企业出口国内增加值率的影响。研究发现,双边外交关系发展会提高企业出口国内增加值率,该结果经过变量替换、更换回归方法等稳健性检验后依旧成立。机制检验表明,双边外交关系发展对企业出口国内增加值率的影响主要通过降低国内外中间品相对价格和提高企业加成率两条途径实现。异质性分析发现,双边外交关系发展会显著提高低技术企业出口国内增加值率,但对高技术企业出口国内增加值率却表现为抑制作用;与“一带一路”沿线国家相比,双边外交关系发展对企业出口国内增加值率的提升作用在非“一带一路”沿线国家更大。进一步分析表明,金融危机、加征关税和经济政策不确定性会削弱双边外交关系发展对企业出口国内增加值率的提升作用。

Vigorous particle collisions and mechanical processes occurring during high-velocity pneumatic con- veying often lead to particle degradation. the resulting particle size reduction and particle number increase will impact on the flow characteristics, and subsequently affect the electrostatic type of flow measurements. this study investigates this phenomenon using both experimental and numerical meth- ods. Particle degradation was induced experimentally by recursively conveying the fillite material within a pneumatic pipeline. the associated particle size reduction was monitored. three electrostatic sensors were embedded along the pipeline to monitor the flow. the results indicated a decreasing trend in the electrostatic sensor outputs with decreasing particle size, which suggested the attenuation of the flow velocity fluctuation. this trend was more apparent at higher conveying velocities, which suggested that more severe particle degradation occurred under these conditions. Coupled computational fluid dynamics and discrete element methods （CFD-DEM） analysis was used to qualitatively validate these experimental results. the numerical results suggested that smaller particles exhibited lower flow velocity fluctua- tions, which was consistent with the observed experimental results. these findings provide important information for the accurate aoolication of electrostatic measurement devices in oneumatic conveyors.
