Summary: Silicon has been found to enhance the growth and biomass of giant reed plants under antimony toxicity, alleviate the negative effects of antimony on photosynthesis and photosynthetic pigments, and enhance root lignification to restrict antimony translocation. These findings suggest that silicon treatment promotes overall plant growth by improving photosynthetic parameters and decreasing antimony translocation from root to shoot in giant reed.

Summary: This study evaluated the behavior of four Mediterranean clones of Arundo donax L. (giant reed), and found that there were no significant differences in most physiological and biomass parameters among the clones. However, significant differences were observed in chromosome count, with each clone having a different number of chromosomes (ranging from 98 to 122). Surprisingly, there was no correlation between chromosome numbers and physiological or biomass responses.

Summary: This study found that Arundo donax (A. donax) has the potential for phytoremediation of combined mercury (Hg) and cadmium (Cd) pollution under neutral conditions, but the combined Hg-Cd stress negatively affects the growth and physiological properties of A. donax and aggravate oxidative stress in the plant. It is also observed that A. donax can transform a portion of Hg2+ into Hg-0, and phytovolatilization and phytostabilization are the main mechanisms for the remediation of Hg and Cd by A. donax.

Summary: In this study, bisphenol A aniline based benzoxazine was reinforced with natural Arundo donax L. fibers treated in different ways at various loadings to investigate the dynamic mechanical properties, morphological stability, and thermal stability of the composites. The results showed that composites reinforced by alkali- or combined-treated fibers exhibited higher storage and loss moduli, indicating great enhancement in properties, likely due to improved fiber-matrix adhesion and compatibility. Additionally, the thermal behavior and char yield of the composites were significantly influenced by the nature of the chemical treatment used on the natural reinforcements.

Summary: In distributed key-value stores, the selection of replica servers is crucial for reducing response time. However, existing replica selection algorithms suffer from poor timeliness of feedback information. To address this issue, this paper proposes an Accelerated Information Dissemination (AID) mechanism that allows both client and replica server to store records about the status of replica servers and piggyback multiple records in the key-value pairs. The results show that AID significantly improves the timeliness of feedback information, especially in large-scale deployments.

Summary: Constructed wetlands (CWs) with biochar addition showed enhanced removal rates for NH4+-N, total nitrogen, and chemical oxygen demand, while reducing N2O emissions. Nitrous oxide (N2O) emission was mainly contributed by nitrification, denitrification, and simultaneous nitrification and denitrification processes. Adding biochar resulted in significant reduction rates for these processes. The relative abundance of nitrogen-transforming microbes increased after biochar addition, promoting nitrogen removal and reducing N2O emissions. Functional gene copy number and enzyme activity responsible for nitrogen conversion were increased with biochar addition, facilitating efficient NH4+-N oxidation and nitrite elimination, thus reducing N2O emissions.

Summary: The COVID-19 pandemic in northern Taiwan resulted in the implementation of Level 3 alert measures, significantly impacting air quality and providing an unprecedented opportunity to understand future control strategies for air pollutants. This study comprehensively investigated the variations in sources, chemical characteristics, and human health risks of PM2.5. The study found that PM2.5 mass concentrations and inorganic ions were greatly reduced during the alert period, while organic matter and elemental carbon decreased to a lesser extent, causing a shift in the chemical composition of PM2.5. The study also identified the primary sources of PM2.5 and highlighted the need for continued efforts in reducing carbonaceous matter emissions.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
