3Piperazine:Its role in the discovery of pesticides显示文摘Derivatives of piperazine,which is one of the most important heterocycles,are often used as linkers to connect active substructures that show promising bioactivities,especially in the field of agrochemicals.From 2000 to 2022,many piperazine-containing compounds were found to exhibit excellent activities against fungi,bacteria,insects,plant viruses,and weeds and have also been used as plant growth regulators.Currently,the development of novel pesticides to prevent the invasion of crop pathogens and ensure the quality and yields of crops is still needed.We herein investigated and summarized the role that piperazine plays in the discovery of pesticides to provide a comprehensive summary of the broad activities of piperazine derivatives in agricultural applications and offer a potential reference for novel pesticide design using piperazine-containing compounds.Moreover,structure–activity relationships(SARs)analyses of bioactive piperazine-containing compounds are also discussed for a deeper understanding.Wei Zhang Shengxin Guo Lijiao Yu Ya Wang Yonggui Robin Chi Jian Wu 2023Chinese Chemical Letters2023,34,8:0
4Green Multicast Grooming Based on Cross-Shared Protection in Optical WDM Networks显示文摘Currently,multicast survivability in optical network obtains more attention.This paper focuses on the field of multicast grooming shared protection in green optical network and designs a novel auxiliary graph and a shared matrix to address the survivable multicast resource consumption.This paper also proposes a new heuristic called Green Multicast Grooming algorithm based on spanning path Cross-Shared protection(GMGCSP),in which network reliability,energy efficiency and resource utilization are jointly considered.Simulation results testify that,compared to other algorithms,the proposed GMG-CSP not only has lower blocking probability and higher bandwidth utilization ratio,but also saves more energy.YU Cunqian LIU Yejun JIANG Peipei ZHU Lijiao GOU Lei HAO Liyuan 2014China Communications2014,11,5:0
5Unexpected phenotypes of malformations induced in Xenopus tropicalis embryos by combined exposure to triphenyltin and 9-cis-retinoic acid显示文摘Xenopus tropicalis embryos were exposed for 48 hr to the mixtures of 5 g Sn/L triphenyltin(TPT), which is a well-known endocrine disruptor, and 0.25–5 g/L 9-cis retinoic acid(9c-RA), which is the natural ligand of retinoid X receptor. The phenotypes induced by combined exposure were more variable than those resulting from single exposure to either TPT or 9c-RA. The prominent phenotypes included underdeveloped head structures, abnormal eyes, narrow fins, enlarged proctodaeum, etc. Especially, combined exposure induced unexpected notochord malformations, which ranged from small swellings of the surface of the tails to the extension and extrusion of notochord out of the posterior tails. Compared with the 5 g Sn/L TPT-treated group, the index of fin deficiency was not affected, and the index of axis deficiency was significantly increased with increasing RA concentrations in the mixtures. Our results suggest that combined exposure to TPT and 9c-RA induced not only more variable phenotypes of malformations than exposure to single compound but also some new and unexpected phenotypes.Jingmin Zhu Lin Yu Lijiao Wu Lingling Hu Huahong Shi 2014Journal of Environmental Sciences2014,26,3:0
6Hydrazone derivatives in agrochemical discovery and development显示文摘As a common active substructure,hydrazone has attracted increasing attention and is considered essential for pesticide discovery.It has been widely regarded as a potential insecticidal,antibacterial,antifungal,antiviral,and herbicidal agent.In this review,we highlight the pesticide versatility of hydrazone fragments and provide a comprehensive summary of the biological activity,structure-activity relationship analysis(SARs),and primary mechanism of their analogs.This profile is expected to give valuable information for discovering new pesticides.Ya Wang Shengxin Guo Lijiao Yu Wei Zhang Zhenchao Wang Yonggui Robin Chi Jian Wu 2024Chinese Chemical Letters2024,35,3:0
7Multistate Models for the Recovery Process in the Covid-19 Context:An Empirical Study of Chinese Enterprises显示文摘The Covid-19 pandemic has severely affected enterprises worldwide.It is thus of practical significance to study the process of enterprise recovery from Covid-19.However,the research on the effects of relevant determinants of business recovery is limited.This article presents a multistate modeling framework that considers the determinants,recovery time,and transition likelihood of Chinese enterprises by the state of those enterprises as a result of the pandemic(recovery state),with the help of an accelerated failure time model.Empirical data from 750 enterprises were used to evaluate the recovery process.The results indicate that the main problems facing non-manufacturing industries are supply shortages and order cancellations.With the increase of supplies and orders,the probability of transition between different recovery states gradually increases,and the recovery time of enterprises becomes shorter.For manufacturing industries,the factors that hinder recovery are more complex.The main problems are employee panic and order cancellations in the initial stage,employee shortages in the middle stage,and raw material shortages in the full recovery stage.This study can provide a reference for enterprise recovery in the current pandemic context and help policymakers and business managers take necessary measures to accelerate recovery.Lijiao Yang Yu Chen Xinyu Jiang Hirokazu Tatano 2022International Journal of Disaster Risk Science2022,13,3:0
