Summary: Strategies based on virtual water have sparked controversy in alleviating water stress in regions with scarce water resources. While advocates emphasize the potential low cost and high efficiency, opponents criticize the oversimplification and neglect of important factors other than water. A detailed analysis of the strategy's effects on water use and socioeconomic development is crucial in order to comprehend its strengths and weaknesses and to ensure a reasonable and scientific implementation.

Summary: This study analyzed the interaction among watershed, food-producing, and food-demanding areas through the system of physical-virtual water flows and local food networks. The analysis focused on the transboundary water-food nexus, even if there was no geographical connection. Using the gravity model, the potential food network of local rice among 47 prefectures in Japan was analyzed, and the physical-virtual water flows were estimated. The study found that changes in self-supply ratios of local rice had varying influences on different prefectures based on the analysis of the food network.

Summary: This study uses complex network theory to investigate the structure and stability of China's virtual water trade network in major crop trade. The results show an overall increase of 23.6% in virtual water trade over time, with stable trade relations but changes in some regions. At the spatial scale, the virtual water trade network exhibits high variability and vulnerability. The trade of virtual water from water-poor areas to water-rich areas contradicts the distribution of water resources.

Summary: Virtual network embedding (VNE) is essential for deploying virtual networks (VNs) on shared substrate network (SN) resources. However, traditional VNE methods struggle to meet the scalability and diversity demands of multi-dimensional virtual networks (MD-VNs). This study proposes a repeatable MD-VNE problem and a heuristic embedding method (ReMiDvne) to address these challenges. Experimental results demonstrate the superior performance of ReMiDvne compared to baseline approaches, both in simulation and real-world experiments.

Summary: Food and water resources are closely interconnected through economic supply chains, with some critical sectors acting as transmission centers. Improving the production efficiency of these sectors could indirectly reduce water usage in the entire supply chain. The study identifies agricultural sectors in Shandong, Heilongjiang, and Hubei as the top three transmission sectors, emphasizing the importance of inter-regional and inter-sectoral cooperation.

Summary: In recent years, there have been continuous investments in new irrigation dams across Africa, resulting in the emergence of new irrigated areas. The ability to irrigate previously rainfed land increases crop production and agricultural value. This study uses crop water modeling to determine the economic benefits of irrigation in the command areas of major African dams built between 2000 and 2015, and evaluates the increase in agricultural revenues resulting from access to water for irrigation.

Summary: In this study, the transition to turbulence in a flat plate boundary layer was investigated using visibility analysis and network science metrics. The results showed the evolution of the flow from laminarity to turbulence and the effects of free-stream turbulence, and demonstrated the capability of the network-based approach to identify the onset markers for transition using only the streamwise velocity time-series.

Summary: Recent studies have mostly focused on the impact of large tropical cyclones on shorelines, disregarding the effects of less intense but more frequent events. This study analyzes the influence of offshore tropical storm Melissa on groundwater along the North America Atlantic coast. The findings show that Melissa led to a significant increase in groundwater level and specific conductivity, with a longer recovery time for conductivity. The study suggests that the increasing frequency of moderate storms will have a significant ecological impact on vegetated shorelines.

Summary: This study proposes a network-based approach to identify and characterize the large-scale coherent motion of blood in the healthy human aorta, reducing information loss. The anatomical length of persistence of large-scale coherent motion in the healthy thoracic aorta is influenced by the blood flow rate values rather than geometric attributes. Flow inertia plays a major role in the transport of coherent fluid structures.

Summary: Research and Development (R&D) is crucial for innovation, technological progress, sustainable development, and economic growth. In this study, a new perspective is introduced to analyze international trade by incorporating R&D and industrial activities. New indices, RDE and RDI, are proposed to summarize the R&D content of countries' export and import baskets, providing insights into the evolution of R&D choices and their impact on trade, innovation, and development. These indices offer complementary information to traditional measures of development and economic growth and can help explore the relationship between environmental performance and countries' role in international trade.

Summary: Using a multiscale approach, this study finds a connection between high time irreversibility levels and coherent motions in wall-bounded turbulence. Time irreversibility is a characteristic feature of non-equilibrium phenomena such as turbulent flows, and its connection with coherent motions in wall turbulence has not been investigated before. The outcomes reveal a strong correlation between irreversibility levels and coherent structures in both turbulent channel and boundary layer flows.

Summary: A modeling framework is proposed to assess the evolution of energy trade under current and future scenarios up to 2050. The projected energy trade network in 2050 varies under each shared socioeconomic pathway (SSP) of the future, with Canada, USA, Venezuela, and China projected to dominate the global trade network. The Canada-USA trade link is expected to remain the most dominant fossil fuel trade link up to 2050.

Summary: Transnational corporations play a significant role in reallocating global water resources, but their actions are not well-regulated. This study examines the virtual water trade of the top 9 transnational corporations involved in Brazilian soy trade and finds that the total virtual water flow increased from 43 billion m³ to 100 billion m³ between 2004 and 2018. The largest soy traders displace twice as much virtual water as top-importing countries, emphasizing the importance of corporate water stewardship and sustainable supply chains.

Summary: Mixing of inertial point particles in turbulent channel flow at Re-z = 950 is studied using direct numerical simulations. The study considers the release of inertial particles, with varying Stokes number, from different positions inside the channel and analyzes their rate of coming close to each other. A Lagrangian framework is employed to analyze trajectories and study mixing and dispersion problems. The research provides a comprehensive understanding of mixing in an anisotropic turbulent flow by varying the release position of particles along the wall-normal direction. Moreover, the effects of particle inertia are analyzed and found to depend on the position and alignment of the sources due to the dependence of the flow timescales on the distance from the wall.

Summary: Technical Summary
Intra-African environmental migration is a bleak reality, with warming trends, aridification, and extreme climate events driving millions of people to move within sub-Saharan Africa. This meta-analysis examines 87 case studies to investigate the relationship between environmental changes and migration in the region. The study uses a combination of quantitative and qualitative methods to analyze the data and offers insights into the complex web of environmental drivers and the role of non-environmental factors in vulnerability and resilience to environmental change.
