Summary: Smart cities strive to enhance sustainability by utilizing advanced technologies and resources in an intelligent way, but the recipe for implementing a sustainable smart urban ecosystem is not fully understood. Research findings suggest that the viability of smart urban ecosystems relies on the implementation of a technobureaucratic governance model, citizen-centeredness, community engagement, and the development of datafication and computerization technologies.

Summary: Groundwater quality assessment is crucial for understanding the suitability of groundwater resources. This study proposed a method combining self-organizing map and entropy-based weight determining method to assess groundwater quality. The study classified sampling points into five clusters, indicating different sources of contamination. The results showed that groundwater affected by domestic sewage discharge sources had better quality compared to other sources in the study area.

Summary: There is no one-size-fits-all solution for global energy sustainability. This paper assessed a country's energy sustainability using 28 indicators and presented the results on a 2D map using Kohonen's self-organizing maps. Eight clusters of countries were found based on the analysis, with green being the most sustainable and red being the least sustainable. This method can visualize a country's distance to the best achievers and identify areas for improvement.

Summary: This study investigated the influence of land use types on nitrate-nitrogen contamination in groundwater in a typical rural area in South Korea. The findings showed that nitrate-nitrogen mainly originated from public facilities and livestock areas, with different land use types having distinct recharge routes for nitrate-nitrogen into the groundwater system. The shallow groundwaters in the study area were classified into three clusters based on their chemical constituents and land-use properties using SOM, PCA, and HCA.

Summary: This study presents two models of self-organizing map (SOM) formulated as an optimal control problem. The first model focuses on the weight updating equation of the best matching units in each iteration, while the second model considers the weight updating equation of all nodes in the SOM. The SOMOC2 model performs better by considering all nodes in the Hamiltonian equation and produces a greater improvement in terms of mean quantization error.

Summary: The study shows that human activities intensification has a negative effect on biodiversity in pond ecosystems, impacting density and richness across all trophic levels. Direct effects primarily affect primary producers, while indirect effects mediated through water nutrients influence the diversity of invertebrate communities. Indirect effects through trophic network cascades are mainly observed within the fish community.

Summary: Lake Balaton, the largest shallow lake in Central Europe, is affected by the Zala River. The Kis-Balaton Water Protection System (KBWPS) was constructed to improve water quality, but toxic cyanobacterial blooms were still observed. The KBWPS acts as a significant buffering zone, protecting the water quality of Lake Balaton. Regular monitoring of cyanobacteria and cyanotoxins in this ecosystem is crucial.

Summary: Plankton communities in shallow lentic ecosystems show contrasting responses to human pressure and environmental changes. Phytoplankton abundance is negatively correlated with human impact, while zooplankton abundance and species richness increase with increasing human impact. Hydrological connectivity is an important predictor of both phytoplankton and zooplankton diversity and composition.

Summary: This paper provides a comprehensive overview of the threats, risks, and integrated water management elements in freshwater ecosystems. It discusses the impacts of human activities and conservation issues related to freshwater systems. The complex matrix of stressors, including pollution, habitat fragmentation, and unsustainable exploitation, significantly affects the qualitative and quantitative changes in freshwater ecosystems and their ability to sustainably provide products and services to human societies. Only internationally integrated policies, strategies, assessment, monitoring, management, protection, and conservation initiatives can prevent the long-term deterioration of Earth's freshwater resources.

Summary: The red alga Bangia atropurpurea was first observed in Serbia in 1991, with sporadic sightings in various locations over the years. More intensive research from 2017 to 2020 revealed its preference for habitats with running water, high oxygen levels, slightly alkaline conditions, low inorganic nutrients, and a wide range of temperature and conductivity values. Due to its limited distribution, low abundance, and threats from anthropogenic impacts and small hydropower plants, the species is considered endangered and strictly protected in Serbia.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
