Dear Editor,industrial Internet of things(IIoT) is a typical application of cyberphysical system(CPS). In the IIoT, wireless communication is an inevitable trend to replace the deployment-limited wired transmission for cases with large-scale and mobile devices. However, wireless communication gives rise to critical issues related to physical security, such as malicious detections and attacks [1].

Insights from untargeted metabolomics: revealing potential marker compounds into the maturation of fermented chili

引用

Food Science and Human Wellness 2025年

作者： Shiyu Liu Mingyuan Yang Jianhua Zhao Meijuan Lei Jinlin Han Min Xu Ping Liu Jie Tang Hongbin Lin School of Food and Bio-engineering， Xihua University China Agricultural University-Sichuan Advanced Agricultural & industrial Institute Chongqing Key laboratory of Speciality Food Co-Built by Sichuan and Chongqing Food microbiology Key laboratory of Sichuan Province

Chili fermentation is one of the most important processes in the production of Pixian Douban (PXDB)， which determines the flavor and product quality of PXDB. However， the maturity of fermented chili mainly depends on empirical judgment， which can not satisfy the need for standardized production of PXDB. Therefore， this study aimed to investigate volatile and non-volatile substances during the maturation process and to find markers related to the maturity of fermented chili. GC×GC-MS combined with multivariate statistical analysis revealed that 2-methoxy-3-isobutyl pyrazine， linalool， 3-(methylthio)propionaldehyde， myrcene， and decanal (ROAV ≥ 1， VIP > 1， P < 0.05) were regarded as potentially active aromatic markers for differentiating fermentation time. Additionally， UPLC-QTOF-MS combined with multivariate statistical analysis resulted that 14 compounds can serve as differentiated non-volatile compounds. The correlation of maturity-related physico-chemical indicators with volatile and non-volatile compounds revealed that three volatile compounds (2-methoxy-3-isobutylpyrazine， linalool， and decanal) along with fructose and adenosine could serve as markers for evaluating the maturity of chili. This study is expected to establish a standard for the determination of maturity the fermented chili and lay the foundation for intelligent production of PXDB.

From Static and Dynamic Perspectives:A Survey on Historical Data Benchmarks of Control Performance Monitoring

引用

IEEE/CAA Journal of Automatica Sinica 2025年第2期12卷 300-316页

作者： Pengyu Song Jie Wang Chunhui Zhao Biao Huang the State Key laboratory of industrial Control Technology College of Control Science and Engineering Zhejiang University IEEE the Department of Chemical and Materials Engineering University of Alberta

In recent decades, control performance monitoring(CPM) has experienced remarkable progress in research and industrial applications. While CPM research has been investigated using various benchmarks, the historical data benchmark(HIS) has garnered the most attention due to its practicality and effectiveness. However, existing CPM reviews usually focus on the theoretical benchmark, and there is a lack of an in-depth review that thoroughly explores HIS-based methods. In this article, a comprehensive overview of HIS-based CPM is provided. First, we provide a novel static-dynamic perspective on data-level manifestations of control performance underlying typical controller capacities including regulation and servo: static and dynamic properties. The static property portrays time-independent variability in system output, and the dynamic property describes temporal behavior driven by closed-loop feedback. Accordingly,existing HIS-based CPM approaches and their intrinsic motivations are classified and analyzed from these two ***, two mainstream solutions for CPM methods are summarized, including static analysis and dynamic analysis,which match data-driven techniques with actual controlling behavior. Furthermore, this paper also points out various opportunities and challenges faced in CPM for modern industry and provides promising directions in the context of artificial intelligence for inspiring future research.
