FedSW-TSAD: SWGAN-Based Federated Time Series Anomaly Detection.

As distributed sensing technologies evolve, the collection of time series data is becoming increasingly decentralized, which introduces serious challenges for both model training and data privacy protection. In response to this trend, federated time series anomaly detection enables collaborative analysis across distributed sensing nodes without exposing raw data. However, federated anomaly detection experiences issues with unstable training and poor generalization due to client heterogeneity and the limited expressiveness of single-path detection methods.

The nitrate dynamics affected by land use and saltwater intrusion in the coastal hydrologic interaction systems.

Nitrate dynamics in the coastal hydrological system is concerned with the impact of nitrate levels on ecological stability and plays an important role in the global nitrogen cycle. However, the complex nitrate source and transport processes in the coastal area and the contribution of nitrogen cycle transformation processes make it a challenge to reveal the nitrate dynamics in the coastal hydrological system. In this study, we investigated the effects of land use types and hydrological interactions on nitrate dynamics in the coastal region using nitrogen composition combined with multi-isotope and Bayesian mixing modeling, focusing on the differences in paleo-saltwater intrusion area (PSIA) and modern seawater intrusion area (MSIA).

Interaction between 6PPD/6PPD-Q and natural Fe-Mn nodules: Performance and mechanism of adsorption and oxidative transformation.

The widely used rubber antioxidant N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its ozonated product, 6PPD-quinone (6PPD-Q), are highly toxic to aquatic life, yet understanding on their environmental behaviors is limited. This study comprehensively investigated their adsorption and transformation processes on natural Fe-Mn nodules (NFMN), which commonly exist in sediments and soils through a combination of diverse experimental and computational methods. The maximum adsorption capacity of 6PPD-Q (719.

Modeling the elongation of commingled BTEX and chlorinated ethene plumes undergoing biodegradation with a multi-level substrate interaction module.

Multi-solvent co-contamination is a common phenomenon found in organically contaminated groundwater. A mathematical approach based on multi-level substrate interactions was developed to describe the microbial growth and the corresponding biodegradation of highly chlorinated ethenes (CEs) in the presence of the co-contaminant BTEX. The Reactive Transport in 3 Dimensions (RT3D) model was applied to integrate proposed mathematical model into reactive transport framework.

Oxidative degradation of sulfamethazine by manganese oxide supported biochar activated periodate: Effect and mechanism.

In this study, manganese oxide supported biochar (MBC) was used as a catalyst of periodate (PI) for the oxidative degradation of sulfonamide antibiotic sulfamethazine (SMZ). The degradation rate of 10 mg/L SMZ reached 99 % in 60 min in the MBC/PI system, and the optimal condition was pH 3.5, 0.

Global research trends on biomarkers for cancer immunotherapy: Visualization and bibliometric analysis.

The global burden of cancer continues to grow, posing a significant public health challenge. Although cancer immunotherapy has shown significant efficacy, the response rate is not high. Therefore, the objective of our research was to identify the latest research trends and hotspots on biomarkers from 1993 to 2023.

An approach for estimating microbial growth and chlorinated ethenes biotransformation in groundwater based on discrete observations.

The bioremediation of chlorinated ethenes (CEs) contaminated groundwater is attracting increasingly attention in practical remediation projects. However, modelling of microbial metabolic processes under the constraints of substrate and environmental factors is inadequate. This study developed a new kinetic model, which incorporated the logistic model and Dual-Monod kinetic to represent the interaction between the controlled microbial growth and the bioavailable substrates in CE-contaminated groundwater.

Persulfate activation with biochar supported nanoscale zero- valent iron: Engineering application for effective degradation of NCB in soil.

Nitrochlorobenzene (NCB) is very common in pesticide and chemical industries, which has become a major problem in soil environment. However, the remediation of NCB contaminated soil is received finite concern. Using biochar as a substrate for nanoscale-zero valent iron (nZVI/p-BC) to activate peroxodisulfate (PDS), a novel heterogeneous oxidative system had been applied in the current study to remediate NCB contaminants in soil.

Adsorption Performance and Mechanisms of Tetracycline on Clay Minerals in Estuaries and Nearby Coastal Areas.

Clay minerals in sediments have strong adsorption capacities for pollutants, but their role in the distribution of antibiotics in estuaries and nearby coastal areas is unclear. We evaluated the clay mineral montmorillonite (SWy-2) adsorption capacity for tetracycline (TC). We assessed the adsorption capacity of SWy-2 for TC by measuring the removal percentage of 30 mg/L TC over time.

Effect of NaNO, NHCl and urea on the fate and transformation of various typical microplastics in porous media.

Understanding the transport behaviors of microplastics (MPs) in porous media is crucial in controlling MPs pollution. Given nitrogen is one of the most important nutrients in soil and groundwater systems, unclearness of the transport behaviors of microplastics (MPs) under various nitrogen conditions may inhibit the acknowledgment of MPs fate. For this reason, this study innovatively investigates the transport characteristics of four kinds of typical MPs (PVC MPs, PMMA MPs, PET MPs, and PP MPs) under various NaNO, NHCl and urea conditions via column experiments numerical models.

Bioremediation of chlorinated ethenes contaminated groundwater and the reactive transport modeling - A review.

Improper disposal of chlorinated ethenes (CEs), a class of widely used solvents in chemical manufacturing and cleaning industries, often leads to severe groundwater contamination. In situ bioremediation of CE-contaminated groundwater has received continuous attention in recent years. The reactive transport simulation is a valuable tool for planning and designing in situ bioremediation systems.

Degradation of Diclofenac by Loaded Solid Superbase-Activated Persulfate.

Alkali-activated persulfate (PS) is widely used in situ in chemical oxidation processes; however, studies on the innovation of the alkali activation process are very limited. Two supported solid superbases, namely KNO/γ-AlO (KAl) and KNO/SBA-15/MgO (KSM), respectively, were prepared and used to activate persulfate to degrade DCF in this work. The results showed that the superbases elevated the solution pH once added and thus could catalyze persulfate to degrade diclofenac efficiently above pH 10.

Optimization of water quality index models using machine learning approaches.

To optimize the water quality index (WQI) assessment model, this study upgraded the parameter weight values and aggregation functions. We determined the combined weights based on machine learning and game theory to improve the accuracy of the models, and proposed new aggregation functions to reduce the uncertainty of the model. A new water quality assessment system was established, and took the Chaobai River Basin as a case study.

Source apportionment and health risk assessment of chemicals of concern in soil, water and sediment at a large strontium slag pile area.

Strontium (Sr) is an alkaline earth metal that has adverse effects on bone tissue, but received little attention compared to other often-studied metals. This study analyzed the contents/concentrations of Sr, barium (Ba), sulfate (SO), sulfide (S), and six common metals in 209 multi-media samples, including slag, soil, groundwater, surface water, and sediment, collected at a large Sr slag pile area. Sr was the dominant chemical of concern (COC) in the soil and groundwater, with contents/concentrations being 35.

Case of catatonia misdiagnosed with coma.
