Summary: Marine and estuarine environments are often contaminated by microbiological factors, which have negative effects on their use and human health. This study compared fecal indicator bacteria (FIB) and bacterial pathogen profiles in two ecosystems in Agadir Bay over a two-year period, to investigate the impact of human activities. The study found that Vibrio target pathogens were frequently detected, while Salmonella was less prevalent. In addition, other pathogenic bacteria such as Cronobacter sakzakii, Pseudomonas fluorescens, and Aeromonas hydrophila were also identified.

Summary: The research demonstrates that the survival of fecal indicator bacteria, pathogenic microorganisms, and other bacterial and viral surrogates in freshwater differs by sample type (sediment/water) and season. There is a greater microbial persistence in sediments than in water over time, with differences in survival among microorganisms in relation to the fecal indicator bacteria E. coli and enterococci. Further investigation is needed to determine the best surrogates to assess pathogen survival in agricultural water for fresh produce.

Summary: This study compared the responses of bacterial community, human pathogenic bacteria (HPB), and fecal indicator bacteria (FIB) to sludge pretreatment-anaerobic digestion (AD). The results showed that AD drove the variation of bacterial community and led to the convergence of HPB communities in pretreated sludge. FIB was found to be suitable for characterizing general pathogen removal rather than showing the real pattern of HPB. AD-related parameters played an important role in assessing pathogen inactivation.

Summary: This study investigated the microbial risks associated with mechanical berry harvesters used in commercial blueberry production. The results showed significant differences in microbial loads among harvester surfaces, with high levels of total aerobes and total yeasts and molds recorded on horizontal surfaces and those located at the bottom of the harvester. There was evidence that passage through the harvester may increase the levels of environmental microorganisms on fruit in the field. Fecal indicator organisms were detected only sporadically and at very low densities on harvester surfaces and blueberry fruit.

Summary: In this study, magnetic graphene oxide was used to immobilize diamine oxidase for the development of a colorimetric biosensor to detect histamine in fish. The biosensor showed a strong response to histamine and had negligible interference from other compounds. The etching induced multicolor change of the gold nanorods indicated the presence of varying levels of histamine in the fish, which was consistent with the overall change in the content of total volatile basic nitrogen. This colorimetric biosensor has great potential in evaluating the freshness of red-fleshed fish high in histamine.

Summary: In current industrial production, defective products have become a bottleneck for enterprises to improve product quality. Artificial detection is inferior to machine vision based detection in terms of speed, accuracy, and stability. However, data-driven based supervised recognition algorithms often fail in the presence of unknown defects. This paper proposes a detection model, called Zero-DD, for surface defects of industrial products with zero samples, which achieves high-precision detection by being sensitive to unknown defects.

Summary: In this paper, a new method is proposed to quantitatively evaluate the quality of carrier phase observation signals of the BeiDou Navigation Satellite System (BDS) during weak and moderate geomagnetic storms. The newly defined PAS (Percentage of Affected Satellites) index shows significant anomaly changes during moderate geomagnetic storms and has good correlations with the geomagnetic storm Kp index and Dst index. The proposed PAS index has a good indication for both BDS2 and BDS3 satellites and can be validated by calculating the Precise Point Positioning (PPP) positioning error.

Summary: Two finite element models were established to analyze and evaluate the stability of lumbar spine and the risk of cage subsidence after different minimally invasive fusion operations. The results showed that PE-PLIF had better segmental stability, lower pedicle screw rod system stress, and lower risk of cage subsidence compared to MIS-TLIF. The findings suggest selecting a cage with appropriate height to ensure segmental stability and avoid the risk of subsidence caused by a cage with large height.

Summary: The present study investigates the phenomenon of reduced malonaldehyde (MDA) content in muscle foods after plasma-activated water (PAW) treatment. The study determines the main reactive components in PAW and analyzes the changes in fatty acid composition in tuna muscle after PAW treatment. The results suggest that the reduction in MDA content is not due to the inhibition of lipid oxidation, but rather a reaction between nitrite in PAW and MDA.

Summary: This study used electrodialysis (ED) to control the histamine in fish sauce and investigated the effects of input current, pH, and flow velocity. A statistical model was derived using a Box-Behnken design and response surface methodology, and it identified the optimal operating conditions as 5.1 A input current, pH 3.8, and 40 L·h(-1) flow velocity. Under these conditions, the histamine removal rate reached 53.41% and the histamine content met the allowable limit in fish sauce, while the loss rate of amino nitrogen was only 15.46%. Additionally, the changes in amino acids and volatile compounds differed during ED. The study's findings have positive implications for promoting the safety of aquatic products.

Summary: Spaceborne interferometric synthetic aperture radar (InSAR) techniques are important for landslide detection and monitoring, but they have limitations in detecting high and steep slope landslides. This study proposes sensitivity indices and conducts experimental and statistical analysis to evaluate the feasibility of time-series InSAR monitoring for steep slopes. The results show that the defined indices can quantitatively evaluate the feasibility of InSAR observations with GNSS data and qualitatively evaluate the feasibility of InSAR monitoring without GNSS data. The study demonstrates the generalizability and wide applicability of these indices for landslide monitoring.
