Summary: Estimating dynamic changes in gross primary productivity (GPP) of terrestrial ecosystems has always been challenging. Improved big-leaf and two-leaf light use efficiency (LUE) models have been developed to address the effects of diffuse radiation on GPP. However, their global performance has not been comprehensively evaluated.

Summary: This study explores the impacts of diffuse fraction (DF) on gross primary productivity (GPP) and light use efficiency (LUE) based on a 6-year dataset of carbon flux in a warm-temperate mixed plantation site in North China. The results show that canopy photosynthesis and the apparent quantum yield (alpha) are significantly higher on cloudy days compared to clear days. Increasing DF enhances GPP and LUE, and both variables are mainly controlled by DF and photosynthetically active radiation (PAR). Incorporating DF into the Michaelis-Menten model improves GPP estimation. The findings emphasize the importance of considering DF in carbon sequestration estimation.

Summary: The diffuse radiation fertilization effect, an understudied aspect of atmosphere-biosphere interactions, can have important implications for our understanding of the Earth system and future climate projections. However, limited observational data make it difficult to globally constrain this mechanism. Simulations show that uncertainties in the diffuse fraction of sunlight significantly affect simulated gross primary productivity and terrestrial evapotranspiration.

Summary: The study found that the PAR(dif) fraction and aerosol optical depth have significant impacts on the accuracy of vegetation GPP estimation. In months with high PAR(dif) fractions, both models showed substantial underestimation of GPP; while at sites with high aerosol optical depth, the underestimation of GPP estimation by both models was more pronounced. The TL-LUE model demonstrated better performance in reducing underestimation and root-mean-square error (RMSE) values when the PAR(dif) fraction was above a certain threshold, indicating the sensitivity of GPP estimation models to environmental factors.

Summary: Vegetation phenology, crucial in regulating the terrestrial carbon cycle and climate, has often been studied using inadequate traditional vegetation indices. In this study, we used the latest gross primary productivity product based on solar-induced chlorophyll fluorescence (GOSIF-GPP) to create an annual vegetation photosynthetic phenology dataset from 2001 to 2020 at a spatial resolution of 0.05 degrees. We employed smoothing splines and multiple change-point detection to retrieve phenology metrics for terrestrial ecosystems above 30 degrees N latitude (Northern Biomes), including the start of the growing season (SOS), end of the growing season (EOS), and length of growing season (LOS). Our phenology product can be valuable for validating and developing phenology or carbon cycle models, as well as monitoring climate change impacts on terrestrial ecosystems.

Summary: A study finds discrepancies in historical estimates of global gross primary productivity (GPP) and respiration (RS), highlighting the uncertainty in the terrestrial carbon cycle. Estimating GPP based on RS measurements shows significantly higher GPP values compared to literature estimates, while global RS:GPP ratios are inconsistent with individual site calculations and model results. These discrepancies have implications for our understanding of carbon turnover times and terrestrial sensitivity to climate change.

Summary: In this study, three machine learning models (Support vector regression (SVR), artificial neural network (ANN), and long short-term memory networks (LSTM)) were investigated for predicting GPP in northwest China and compared them with the traditional physical models. The analysis showed that machine learning models performed better than traditional physical models, with SVR model performing the best. When the training data was sufficient, SVR, ANN, and LSTM achieved similar prediction accuracy, but SVR was slightly higher. When the training data was small, the simulation accuracy of SVR was better than ANN and LSTM.

Summary: Mobile reading is seen as a promising method for achieving sustainable education goals. While there have been numerous studies on the mobile reading habits of young readers and their comprehension, there is little focus on college students in China and the factors affecting their engagement in mobile reading. This study aimed to investigate these factors, using interviews and qualitative content analysis. The participants were thirty college students from three universities in Shanghai, China. The results identified various factors influencing college students' engagement in mobile reading, including motivational needs, reading experience, efficacy, and strategies. The intention to be entertained was found to be the most common factor leading to engagement. However, students' difficulties in engaging stemmed from an imbalance between their needs and their engagement. Understanding these factors is crucial for improving mobile reading engagement and assisting college students' independent learning and sustainable development.

Summary: Rice in Northeast China has been positively affected by climate warming, leading to a 10% increase in yield since 1980. Currently, the decrease in chilling and increase in growing degree-day contribute to higher yields, while high-temperature extremes have a limited negative impact. However, as warming continues, the harmful effects of high-temperature extremes will outweigh other positive climate effects. Therefore, climate change mitigation and heat tolerance breeding measures are necessary for rice production in Northeast China.

Summary: This paper proposes a path planning algorithm based on the Theta* algorithm and Timed Elastic Band (TEB) algorithm to solve the difficulty of path planning resulting from the variable configuration of the wheel-legged robot for future deep space explorations. The proposed algorithm divides the path planning of the wheel-legged robot into the planning of the body path and the planning of the wheel path, by simplifying the body as a point using virtual obstacles. Hierarchical planning and multiple optimization algorithms are used to optimize and smooth the path. The simulations show that the proposed algorithm effectively plans the path of the wheel-legged robot by using variable configurations for different types of obstacles.

Summary: Crop-specific, high-resolution phosphorus rate information is crucial for sustainable agricultural fertilizer management in China. The current phosphorus fertilizer dataset based on coarse national statistics lacks accuracy and crop-specific information. This study utilized provincial and county-level data to generate detailed maps of phosphorus rate for rice, wheat, and maize from 2004 to 2016 (CN-P). CN-P provides improved spatial heterogeneity and more accurate estimates of phosphorus rate for each crop compared to the existing dataset. The CN-P dataset has great potential for modeling sustainable agricultural fertilizer management strategies and addressing phosphorus pollution.

The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
