GA-PE-VMD and MSE Methods for Milling Chatter Feature Extraction of Thin-walled Parts
Published 2023-04-01“… In the high-speed milling of aviation parts, due to the low stiffness of thin-walled structure, it is easy to produce chatter. Chatter leads to poor surface quality, dimensional error and reducing the service life of tools and machines.Therefore, a reliable detection method is needed to identify chatter.Aiming at the problem of chatter detection in the milling process of thin-walled structures, a chatter feature extraction method of thin-walled parts based on optimal variational mode decomposition and multi-scale sample entropy is proposed.Firstly, in order to solve the problem of parameter selection in variational modal decomposition, a parameter adaptive method based on genetic algorithm optimization and minimum permutation entropy is proposed. …”

Spatiotemporal Characteristics of Bacterial Communities in Estuarine Mangrove Sediments in Zhejiang Province, China
Published 2025-04-01“…Woeseiaceae, Desulfobulbaceae, Thermoanaerobaculaceae, and Sva1033 (family of Desulfobacterota) exhibited significantly higher relative abundance in the unvegetated area, whereas Bacillaceae and S085 (family of Chloroflexi) demonstrated greater abundance in the mangrove area. Seasonal variations in bacterial community structure are primarily attributed to changes in environmental factors, including temperature and salinity. …”

Reduced representation sequencing reveals genetic diversity and adaptive genetic divergence in Calamus rhabdocladus
Published 2025-07-01“…Redundancy analysis (RDA) identified the driest month (bio14) and the mean temperature of the wettest quarter (bio8) as the two most important environmental factors driving adaptive genetic variation. The Latent Factor Mixed Model (LFMM) identified 955 loci significantly associated with environmental adaptation and successfully aligned 469 genes from related species, which were enriched in functional categories involving cell structure, carbohydrate metabolism, and protein degradation. …”

A New Insight on El Niño Diversity: Decadal Variability in Westerly Wind Bursts
Published 2025-05-01“…ABSTRACT El Niño‐Southern Oscillation (ENSO) is the strongest mode of interannual climate variability, characterized by fluctuations in sea surface temperature (SST) with diverse spatial structures. Recent research has identified two main flavors of El Niño events: Eastern Pacific (EP) and Central Pacific (CP) types, each associated with different physical processes and climatic impacts. …”

Application of Prior-knowledge for Intelligent Gear Fault Diagnosis Under Variable Speed Condition
Published 2018-01-01“…The vibration mechanism analysis of gear transmission system shows that,the vibration response signal of a gear transmission system contains interference components that vary greatly with the speed and cannot reflect the fault information,the fault characteristics in amplitude spectrum of the vibration response signal have less sensitivity to the variation of running speed. These interference components can be removed with the help of prior-knowledge which is composed of structure parameters,operating parameters and the vibration mechanism of gear transmission system. …”
