Summary: This study investigated the quality changes of thyme and black pepper after gamma irradiation under different packaging (modified atmosphere packaging and air packaging). The results showed that irradiation treatment under modified atmosphere packaging increased the essential oil yield and antioxidant activity of the samples, and 14 kGy irradiation enhanced the total phenolic content of black pepper and antimicrobial activity of thyme. During the 6-month storage period, the essential oil yield, antioxidant activity, and antimicrobial activity of thyme decreased, while the antioxidant activity of thyme increased and the antioxidant activity of black pepper in air packaging decreased.

Summary: This study investigates the responses of surface wind stress to mesoscale sea surface temperature anomalies in the northern South China Sea using satellite observations and reanalysis data. The results show that there is a linear relationship between the wind stress perturbation derivatives and the underlying SST gradient field. However, this linear relationship is noisier in satellite observations compared to reanalysis data. The study also finds that high wavenumber perturbations are observed in the satellite data but absent in the reanalysis data within 100 km in the northern South China Sea.

Summary: In this paper, a hybrid energy system based on a combination of hydrogen fueled compressed air energy storage system and water electrolysis hydrogen generator is proposed to improve the utilization efficiency of renewable energy power generation. The system stores excess renewable energy by compressing air and/or producing hydrogen through water electrolysis, and introduces a hydrogen combustor to increase the air temperature during the discharging process. A thermodynamic model is built and energy and exergy analysis show that the proposed system can achieve a round trip efficiency of 65.11%, an exergy efficiency of 79.23%, and an energy storage density of 5.85 kWh/m3. The water electrolysis hydrogen generator and hydrogen combustor have the highest exergy losses among all components, and sensitivity analysis identifies the outlet temperature of the hydrogen combustor and specific energy consumption of the water electrolysis hydrogen generator as crucial factors influencing system performance.

Summary: Arabidopsis NODULIN HOMEOBOX (NDX) is a key regulator of heterochromatin that controls siRNA production and non-CG DNA methylation at pericentromeric regions. Inactivation of NDX leads to differential siRNA accumulation and DNA methylation. Hi-C analysis shows significant chromatin structural changes in the ndx mutant, with decreased intrachromosomal interactions at pericentromeres and increased interchromosomal contacts between KNOT-forming regions.

Summary: This study aimed to compare the discrimination ability and detection limit of visible and short-wave near-infrared hyperspectral imaging features and spectral information on early implicit bruised pears. Physical characteristics were more sensitive than chemical parameters for bruised pears during postharvest storage. The changes in spectral variations at specific wavelengths could explain the bruising changes in pears. Discrimination models based on selected spectral variables could effectively identify bruised pear areas, and the combination of imaging features and spectral variables achieved higher discrimination rates.
