Dynamic interaction between lakes, climate, and vegetation across northern Africa during the mid-Holocene
Authors: Specht Nora Farina , Claussen Martin , Kleinen Thomas 
Published: July 2024

Abstract. During the early Holocene to mid-Holocene, about 11 500 to 5500 years ago, lakes expanded across the Sahel and Sahara in response to enhanced summer monsoon precipitation. To investigate the effect of these lakes on the West African summer monsoon, previous simulation studies prescribed mid-Holocene lakes from reconstructions. By prescribing mid-Holocene lakes, however, the terrestrial water balance is inconsistent with the size of the lakes. In order to close the terrestrial water cycle, we construct a dynamic endorheic lake (DEL) model and implement it into the atmosphere–land model ICON-JSBACH4. For the first time, this allows us to investigate the dynamic interaction between climate, lakes, and vegetation across northern Africa. Additionally, we investigate the effect of lake depth changes on mid-Holocene precipitation, a neglected aspect in previous simulation studies. A pre-industrial control simulation shows that the DEL model realistically simulates the lake extent across northern Africa. Only in the Ahnet and Chotts basins is the lake area slightly overestimated, which is likely related to the coarse resolution of the simulations. The mid-Holocene simulations reveal that both the lake expansion and the vegetation expansion cause a precipitation increase over northern Africa. The sum of these individual contributions to the precipitation is, however, larger than the combined effect that is generated when lake and vegetation dynamics interact. Thus, the lake–vegetation interaction causes a relative drying response across the entire Sahel. The main reason for this drying response is that the simulated vegetation expansion cools the land surface more strongly than the lake expansion, which is dominated by the expansion of Lake Chad. Accordingly, the surface temperature increases over the region of Lake Chad and causes local changes in the meridional surface-temperature gradient. These changes in the meridional surface-temperature gradient are associated with reduced inland moisture transport from the tropical Atlantic into the Sahel, which causes a drying response in the Sahel. An idealized mid-Holocene experiment shows that a similar drying response is induced when the depth of Lake Chad is decreased by about 1–5 m, without changing the horizontal lake area. By reducing the depth of Lake Chad, the heat storage capacity of the lake decreases, and the lake warms faster during the summer months. Thus, in the ICON-JSBACH4 model, the lake depth significantly influences the simulated surface temperature and the simulated meridional surface-temperature gradient between the simulated lakes and vegetation, thereby affecting mid-Holocene precipitation over northern Africa.

Analysis Of Deep Learning-Based Anti-Jamming Method for UAV Communication
Authors: Yang Shuhan 
Published: July 2024

With the increasing popularity of Unmanned Aerial Vehicle(UAV) in both military and civilian applications , it is crucial to ensure the reliability and safety of their signals. In recent years, deep reinforcement learning has proven to be a powerful tool for meeting this challenge. This paper aims to analyze the potential of deep learning in signal jamming countermeasures for UAV communication systems. Traditional jamming countermeasures, such as frequency hopping and Direct Sequence Spread Spectrum (DSSS), are effective to a certain extent. Still, it is difficult to cope with dynamically changing jamming environments due to single mode and low spectrum utilization. On the other hand, deep learning has powerful automatic feature extraction and pattern recognition capabilities, especially the reinforcement learning method based on deep learning, which can realize real-time adaptation of UAVs to environmental changes and automatic optimization of communication strategies. The article focuses on anti-jamming methods based on reinforcement learning and deep reinforcement learning algorithms and proposes a new anti-jamming strategy for UAV communication based on generative adversarial networks (GANs). Although the deep learning method opens up a new way for anti-jamming of UAV communication signals, it still faces the challenges of high demand for computational resources and complex model training in practical applications.

Urban outdoor environment (UOE) is considered an important environmental setting for children’s physical activity (PA) which is recognized as a promising non-pharmacological approach to improve children’s health, particularly in addressing issues like obesity and over-weight. With a substantial increase in the volume of publications on the topics of UOE and PA, the study aims to understand the research advancements by exploring the publication pattern, knowledge foundation, hotspots, and trends. A total of 1203 publications (2000-2023) were re-trieved and processed by the scientometric analysis. Results show the growth of publications in an accelerating speed. The topics covered in the publications are becoming more diversified and interdisciplinary with an emphasis on the public health and environmental study. The hotspots within the domain include: (1) UOE’s influence on children’s health outcomes by PA; (2) the UOE and children’s PA in the neighborhood setting; (3) UOE’s characteristics associated with chil-dren’s travel and recreational behaviors. The research frontiers are gradually moving towards: (1) multi-health benefits from UOE by encouraging PA; (2) UOE and children’s PA in different en-vironmental settings; (3) UOE and children’s PA in the less-developing countries and district, (4) perceptions of UOE and children’s PA. Our findings highlight the importance of fostering the collaborations between different disciplines and districts to advance knowledge and promote evidence-based interventions aimed at improving children's PA through UOE.

A Psicologia Social, apoiada nas epistemes feministas decoloniais e antirracistas e em diálogo com a teoria da bolsa de ficção proposta pela escritora de Ficção científica Ursula Le Guin, convida a narrativas desprovidas do heroísmo humano, desarraigando-nos da ideia de autonomia e a uma aposta radical na imaginação. Neste artigo, buscamos contribuir para uma releitura do gesto da coleta na pesquisa em Psicologia Social, desvencilhando-o de um viés positivista e o atrelando a uma imaginação política feminista. Se prestarmos atenção é inequívoco que, enquanto coletamos, sempre nos escapa algo que cai ao solo como semente, adubo, rastro. Coletar é, também, semear, fertilizar.

Published: July 2024

This study looks at factors influencing the growth of the gross domestic product (GDP) in the United States from 1973 to 2022. Using a multiple regression model, the effects of FDI, rural population growth, and imports of Goods and services were examined about GDP growth. The study found that imports of goods and services, with their value having a positive impact on the dependent variable, are a significant factor in determining the economic growth of the United States. The positive relation of the Imports of goods and services and GDP, growth was attributed to be a measure to control the rising of FDI. It was also discovered that the FDI, Population growth, and rural population are not significant variables in determining economic growth. The study therefore recommends that the United States government and economists prioritize policies and strategies that promote sustainable economic growth, job creation, and innovation. This may involve measures such as investing in education and research, promoting entrepreneurship and small businesses, improving infrastructure, and maintaining a stable and predictable regulatory environment. Additionally, the United States can encourage foreign direct investment (FDI) as a way to attract capital and expertise to the country, but this would depend on the specific circumstances and potential risks and benefits of each investment.
