| 1 | Damping forced oscillations in power system via interline power flow controller with additional repetitive control显示文摘With the continuous expansion of power systems and the application of power electronic equipment, forced oscillation has become one of the key problems in terms of system safety and stability. In this paper, an interline power flow controller (IPFC) is used as a power suppression carrier and its mechanism is analyzed using the linearized state-space method to improve the system damping ratio. It is shown that although the IPFC can suppress forced oscillation with well-designed parameters, its capability of improving the system damping ratio is limited. Thus, combined with the repetitive control method, an additional repetitive controller (ARC) is proposed to further dampen the forced power oscillation. The ARC control scheme is characterized by outstanding tracking performance to a system steady reference value, and the main IPFC controller with the ARC can provide higher damping, and further reduce the amplitude of oscillations to zero compared with a supplementary damping controller (SDC). Simulation results show that the IPFC with an ARC can not only greatly reduce the oscillation amplitude, but also actively output the compensation power according to the reference value of the ARC tracking system. | Shirui Feng Xi Wu Zhenquan Wang Tao Niu Qiong Chen | 2021 | Protection and Control of Modern Power Systems2021，6，1： | 1 |
| 2 | The construction and optimization of engineered yeast chassis for efficient biosynthesis of 8-hydroxygeraniol显示文摘Microbial production of monoterpenoid indole alkaloids(MIAs)provides a sustainable and eco-friendly means to obtain compounds with high pharmaceutical values.However,efficient biosynthesis of MIAs in heterologous microorganisms is hindered due to low supply of key precursors such as geraniol and its derivative 8-hydroxygeraniol catalyzed by geraniol 8-hydroxylase(G8H).In this study,we developed a facile evolution platform to screen strains with improved yield of geraniol by using the SCRaMbLE system embedded in the Sc2.0 synthetic yeast and confirmed the causal role of relevant genomic targets.Through genome mining,we identified several G8H enzymes that perform much better than the commonly used CrG8H for 8-hydroxygeraniol production in vivo.We further showed that the N-terminus of these G8H enzymes plays an important role in cellular activity by swapping experiments.Finally,the combination of the engineered chassis,optimized biosynthesis pathway,and utilization of G8H led to the final strain with more than 30-fold improvement in producing 8-hydroxygeraniol compared with the starting strain.Overall,this study will provide insights into the construction and optimization of yeast cells for efficient biosynthesis of 8-hydroxygeraniol and its derivatives. | Yu Zhang Mengdi Yuan Xinxin Wu Qiuhui Zhang Yuzhu Wang Liming Zheng Tsan-Yu Chiu Huiming Zhang Lei Lan Feng Wang Ying Liao Xuemei Gong Shirui Yan Yun Wang Yue Shen Xian Fu | 2023 | mLife2023，2，4： | 0 |
| 3 | Current strategies for improving limitations of proteolysis targeting chimeras显示文摘Proteolysis targeting chimeras(PROTACs)are bifunctional degrader molecules via hijacking the ubiquitinproteasome system(UPS)to specifically eliminate targeted proteins.PROTACs have gained momentum as a new modality of attractive technologies in the drug discovery landscape,since it allows to degrade disease-related proteins effectively.Although some PROTACs drugs reached the clinical research,they are still facing some bottlenecks and challenges that should not be neglected,such as poor oral bioavailability and potential toxic side effects.To overcome these limitations,herein,we provide an overview of recent strategies for improving the durability of PROTACs by enhancing cell permeability and reducing toxic side effects.Meanwhile,the impact of these strategies on improving oral bioavailability as well as their advantages and drawbacks will also be discussed.This review will give a useful reference toolbox for PROTACs design and further promote its clinical application. | Chunlan Pu Shirui Wang Lei Liu Zhonghui Feng Hongjia Zhang Qianyuan Gong Yueshan Sun Yuanbiao Guo Rui Li | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
