About

Lu Kou is an Assistant Professor and the Director of Undergraduate Studies in the Department of East Asian Languages and Cultures at Columbia University. He holds a BA from Peking University (2010), an MA from Harvard University (2012), and a PhD from Harvard University (2018). His research focuses on medieval Chinese literature and culture, poetry and poetics, historiography, and comparative studies of China’s Middle Period and medieval Europe. As a medievalist, he is engaged in projects examining the discursive battles among rival states in early medieval China and how rhetoric constructed and contested political legitimacy during this period. Additionally, he studies the dialectic between poetry and bureaucratic systems, exploring how themes of work and quotidian life are represented in medieval Chinese poetry from 400 to 900 CE. Prior to his current position, he served as an Assistant Professor of Chinese at Bard College from 2019 to 2022 and as a Visiting Assistant Professor at Williams College from 2018 to 2019.

  BACKGROUND: Okra (Abelmoschus esculentus L. Moench) is an economically important crop and is known for its slimy juice, which has significant scientific research value. The A. esculentus chloroplast genome has been reported; however, the sequence of its mitochondrial genome is still lacking. RESULTS: We sequenced the plastid and mitochondrial genomes of okra based on Illumina short reads and Nanopore long reads and conducted a comparative study between the two organelle genomes. The plastid genome of okra is highly structurally conserved, but the mitochondrial genome of okra has been confirmed to have abundant subgenomic configurations. The assembly results showed that okra's mitochondrial genome existed mainly in the form of two independent molecules, which could be divided into four independent molecules through two pairs of long repeats. In addition, we found that four pairs of short repeats could mediate the integration of the two independent molecules into one complete molecule at a low frequency. Subsequently, we also found extensive sequence transfer between the two organelles of okra, where three plastid-derived genes (psaA, rps7 and psbJ) remained intact in the mitochondrial genome. Furthermore, psbJ, psbF, psbE and psbL were integrated into the mitochondrial genome as a conserved gene cluster and underwent pseudogenization as nonfunctional genes. Only psbJ retained a relatively complete sequence, but its expression was not detected in the transcriptome data, and we speculate that it is still nonfunctional. Finally, we characterized the RNA editing events of protein-coding genes located in the organelle genomes of okra. CONCLUSIONS: In the current study, our results not only provide high-quality organelle genomes for okra but also advance our understanding of the gene dialogue between organelle genomes and provide information to breed okra cultivars efficiently.

  Importance measure is an important method in the field of reliability, which can evaluate the impact of components on the system. The accurate measurement results of the importance of anti-lock system (ABS) can effectively identify the key components and repair them in time, so as to avoid the occurrence of traffic accidents. At first, this paper described the mechanism of ABS. Through the analysis of the wheel movement state by the speed sensor, it is found that the speed change of each tire can reflect the state of ABS to a certain extent, so as to determine that the sensors and regulators of each tire are components of ABS in this paper. Then, according to twenty groups of ABS braking curves on single adhesion coefficient road surface, determined the failure probability and life of each component. The Griffith importance measures (GIM) and Integrated importance measures (IIM) are used to calculate the importance of each component to ABS. Finally, an example is given to illustrate the effectiveness of the method. Based on the IIM value and the maintenance cost of each component, optimization strategies were provided under different conditions with total cost as independent variable.
