Summary: This review highlights the inadequacy of traditional data in measuring poverty and achieving sustainable development goals, proposing satellite earth observation data as a potential supplement for sustainable rural development. The research found that most existing methods operate at a single spatial scale, for a single point in time, and proxy only one socioeconomic metric. It also notes an underutilization of fusion capabilities with disparate datasets.

Summary: This study conducted a systematic literature review and found that only 10 indicators (belonging to SDGs 6, 11, and 15) are currently calculated using satellite Earth observation data, while other satellite data present research opportunities. Therefore, there is a need to update indicators to make use of this valuable source of information and enable worldwide indicator comparison. Additionally, this review is relevant for scientists and policymakers for future actions and policies to better integrate satellite Earth observation data into the Agenda 2030.

Summary: The approach combines the Brunone unsteady friction model with Godunov-type scheme to simulate transient pipe flow. The second-order GTS numerical model is more accurate, stable, and efficient, even for Courant numbers less than one, which is particularly important for unsteady-friction simulations. Even with coarse discretization, the new second-order GTS Brunone model accurately reproduces experimental pressure oscillations in transient flows.

Summary: Lockdown measures due to COVID-19 substantially affected air quality in many cities, with a 58% reduction in traffic volume but only a 4% decrease in PM2.5 relative to baselines. Major chemical components of PM2.5 showed seasonal changes, and reductions were observed in cooking emissions and non-tailpipe emissions. Tailpipe emissions dropped by approximately 54% and were associated with a reduced number of trucks.

Summary: This paper investigates the controller design for a nonlinear model of a water distribution network (WDN). Compared to existing methods, the paper shows that modeling the pumps as port-Hamiltonian systems leads to stability, and local PI controllers can maintain system stability. These controllers are robust and do not require specific knowledge of the equilibrium input. The study also finds that controllers based on physical feedback are valuable in WDN operations. These controllers are useful in mitigating disturbances and tracking setpoints corresponding to assignable equilibria.

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: 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.
