Summary: This study uses satellite data to analyze the spatial and temporal variations of East Asian dust storms and investigate their relationship with vegetation coverage, soil properties, and climatic factors. The results show that improvements in vegetation coverage and favorable climatic factors lead to a decrease in the dust storm index, while increases in surface wind speed, decreases in temperature, and low soil moisture result in an increase in the index.

Summary: According to SDG 15.3, frequent sand and dust storms on the Mongolian plateau pose a long-term challenge in preventing and controlling land degradation. This study utilized MODIS remote sensing data to monitor and analyze these events. Results show a decrease in the overall frequency of sand and dust storms, with the highest occurrence in the first decade. The cross-border regions between China and Mongolia, particularly in southern Mongolia, are identified as centers of high intensity. Precipitation exhibits a strong negative correlation with the affected area, and efforts by the Mongolian and Chinese governments in wind prevention and sand control contribute to regional restoration. Recommendations for policies regarding cross-border sandstorm responses are proposed.

Summary: Despite improvements in climate modeling, global predictions of the terrestrial water cycle remain uncertain. A study using observed data on temperature and humidity suggests that projections are more accurate when both factors are considered, and highlights the urgent need for mitigation policies. The study also identifies a drying trend in the future, particularly in the northern midlatitudes, and emphasizes the importance of adapting to these changes.

Summary: We aimed to improve and evaluate the dust devil parameterization scheme using intensive observations of meteorological and dust devil data in the desert-oasis ecotone of the Xiaotang region in the northern margin of the Taklimakan Desert in combination with GPS sounding in the hinterland of the desert. The results indicated that the temperature difference between the surface and air at a height of 2 m above the ground suitable for dust devil formation was 16℃. In addition, the suitable wind speed (2 m height above ground surface) was 3.2-3.6 m/s. The thermodynamic efficiency of dust devils after improvement was significantly higher than that before improvement. The values were improved by 84.7%, 63.9%, 25.6%, 13.3%, 12.5%, 22.7%, 26.6%, 26.9%, and 21.4% for every hour from 09:00 to 17:00, respectively. The annual number of dust devil occurrences after improvement was 431, which was 55.2% higher than that before improvement. The total annual duration of dust emission after improvement was 181.3 h, which was 95.9% lower than that calculated using day length before improvement and 31.8% higher than that calculated using sunshine time before improvement. The average vertical dust flux of a single dust devil event after improvement was 0.25 g/(m(2)middots), which was 68.8% lower than that before improvement. The average annual dust emission from dust devils per square kilometer was 320.5 t/km(2) and 15.3 t/km(2) before and after improvement, respectively, indicating that the value after improvement was significantly lower (approximately one-twentieth) than that before improvement.

Summary: This study investigated how spatial heterogeneity of vegetation influences saltation occurrence, and found that the spatial distribution of shrubs can affect the relationships among roughness, saltation flux, and vegetation cover. When vegetation is distributed heterogeneously, saltation flux increases, while in homogeneously distributed vegetation, even small cover can suppress saltation flux.

Summary: The response characteristics of soil moisture to rainfall were studied in upland field, paddy field, and forest land in the Chinese red soil region. The results showed that paddy field had the highest average soil moisture, while forest land had the longest lag time and required the highest amount of rainfall to trigger a response. The maximum increment of soil moisture was significantly correlated with rainfall amount. The land use conversion from forest land to upland field and paddy field may decrease rainfall infiltration capacity and increase runoff potential.

Summary: Numerical simulations of soot particle formation and growth in combustion processes are crucial for assessing environmental pollution and predicting industrial particle characteristics. The Soot Aerosol Moment Model (SAMM) has been developed to predict the changes in particle size distribution and morphology, offering comparable information with significantly reduced computation time compared to previous models. SAMM can effectively contribute to the study of chemical mechanisms for soot formation.

Summary: Selecting an appropriate filler is crucial for manufacturing composites with desired properties. Carbon-based nano materials, such as carbon black, graphene, and carbon nanotubes (CNTs), have been extensively studied as reinforcing and conducting fillers. In this study, the piezo-resistive and mechanical properties of composites containing different types of CNTs (multi-walled CNTs and single-walled CNTs) were investigated. The results provide valuable guidelines for the wider application of CNT composites.

Summary: Tomatoes with high levels of lycopene have antioxidative, hypolipidemic, and antidiabetic properties. This study investigated the effects of tomato ketchup and tomato paste on hepatic lipid metabolism and adipogenesis. The results showed that tomato ketchup and tomato paste reduced lipid accumulation and gluconeogenesis markers, and increased fatty acid oxidation in hepatocytes. They also increased adipogenesis and glucose uptake in adipocytes. In addition, a single oral dose of tomato ketchup and tomato paste improved glucose and insulin tolerance in mice. These findings suggest that lycopene-containing tomato ketchup and tomato paste may have beneficial effects on energy metabolism and blood glucose regulation.

Summary: Transition-metal dichalcogenides (TMDCs), a class of versatile two-dimensional materials, have attracted attention due to their properties ranging from metals and semiconductors to insulators. Among them, NbSe2 is a metallic TMDC with substantial potential in energy and electronics fields. In this study, we employed lithium (Li)-ion intercalation-assisted exfoliation to obtain mono layers of NbSe2, by dramatically expanding the interlayer spacing. We propose our own strategy for the high-yield production of NbSe2 monolayers, as there have been limited studies on the optimized intercalation conditions. The highest electromagnetic interference shielding effectiveness (SE) of 20 dB was measured at low amounts (approximately 1.65 mg), based on the electrical conducting nature of NbSe2.

Summary: We examine how the observability of contracts between a plaintiff and attorney affects the efficiency and fairness of environmental conflicts. Using two game-theoretic models (an observable-contract game and an unobservable-contract game), we find two main results: (i) Unobservability of a contract may lead to inefficiency in legal efforts during environmental conflicts; however, (ii) Unobservability of a contract may increase the fairness of the outcome, specifically the plaintiff's probability of winning.
