Summary: Various quasi-zero stiffness (QZS) vibration isolators have been successfully applied in low-frequency vibration isolation in recent years. However, the current approach is limited to compensating the negative stiffness of bistable structures using linear springs. This study proposes a nonlinear compensation method and verifies its effectiveness through a confirmatory system.

Summary: This study proposes a method based on spectral coherence to identify bearing faults. By displaying the energy flow of vibration signal in a two-dimensional plane, the periodic faults of the bearings can be accurately identified. To address the interference and noise issues, an adaptive method is introduced to determine the informative spectral frequency band.

Summary: This study optimized the conditions for ultrasound-assisted extraction of bioactive compounds with antioxidant activity from makiang seeds using response surface methodology. The antimicrobial activity and application potential of the optimized extract were also evaluated. The results showed that the optimized extraction conditions were a temperature of 51.82℃, an extraction time of 31.87 minutes, and an amplitude of 40.51%. Gallic acid was identified as the major phenolic compound in the optimized extract, which exhibited low minimum inhibitory and bactericidal concentrations. Additionally, the addition of the optimized extract improved the stability and extended the shelf life of orange juice.

Summary: The impact of urban noise on residents' physical health and mental condition has become a popular topic of discussion. Social perception data can indirectly reflect the public's perception of noise. This study collected and analyzed public noise complaint data, and found that there were more complaints at night compared to daytime. Different types of noise complaints showed distinct spatial aggregation characteristics, with construction noise complaints being more concentrated. There was a specific correlation between noise complaints and the distribution of different types of POIs, particularly with living commercial and residential locations. This study provides insights for addressing urban noise problems.

Summary: This article comprehensively studies the free vibration analysis of rotating truncated conical shells reinforced with functionally graded agglomerated carbon nanotubes. The shell is modeled based on the first-order shear deformation theory, and effective mechanical properties are calculated using the Eshelby-Mori-Tanaka scheme. The governing equations are derived and numerically solved, confirming the convergence and accuracy of the model while investigating the effects of different parameters on the frequencies.

Summary: This study compares pregnancy outcomes of unvaccinated women infected with SARS-CoV-2 during the Delta and Omicron waves. The study found that infection during the Delta wave was associated with increased need for oxygen support and higher maternal mortality. Disease severity and pregnancy complications were similar between the Omicron wave and the pre-Delta period.

Summary: A highly sensitive and integrated near-infrared CO2 sensor based on quartz enhanced photoacoustic spectroscopy (QEPAS) was developed. The system utilized a novel quartz tuning fork (QTF) and a near-infrared DFB laser diode to achieve a compact acoustic detection module. The minimum detection limit (MDL) of the sensor system was improved to 0.7 ppm, allowing for 24-hour continuous monitoring of CO2 concentration in a greenhouse.

Summary: Response surface methodology was used to optimize the extraction conditions of Ginkgo biloba leaves polysaccharide (GBLP) assisted by ultrasound. The optimum conditions were determined as 30 mL/g liquid to material ratio, 340 W ultrasonic power, and 50 min extraction time, resulting in a GBLP yield of 5.37%. Two chemically modified polysaccharides, CM-GBLP and Ac-GBLP, were obtained from GBLP and their physicochemical properties and in vitro antioxidant activities were compared. The results showed improved solubility and antioxidant activity for the chemically modified polysaccharides, indicating the effectiveness of carboxymethylation and acetylation methods in enhancing polysaccharide properties.
