26 November 2021, Discharge of treated Fukushima nuclear accident contaminated water: macroscopic and microscopic simulations has been published on National Science Review, which is a full affirmation of the students and teachers of the subject group who are generous and rigorous in their learning! NSR officer micro-push high-quality and efficient, reflecting China's outstanding leading journals of the super-class level! Thanks to the director of singhua University's Institute for Ocean Engineering (IOE), Zhang Jianmin's guidance and support, thanks to the editorial department and reviewers for their high evaluation!

The results of this study are of great significance for the prediction of long-term spread of pollutants, the rational response of nuclear wastewater discharge plans and the monitoring of subsequent radioactive material concentrations. In the future, we will continue to deepen our research, Further explore the long-term impact of the discharge of nuclear waste water on the whole ocean and mankind, and provide important decision support for the country and the world to deal with the nuclear wastewater crisis!

Note: National Science Review , whose impact factor in 2021 is 17.275, is the top journal in the multi-discipline domain. For more information, please see the introduction video.

Recently, the "Atoms, Elements and Us" science enlightenment dual picture book, which I participated in compiling, won the first prize of the 36th Excellent Science and Technology Books of the Ten Northern Provinces (Autonomous Regions and Municipalities). 

This set of educational picture books, published by Beijing Science and Technology Press, is specially designed for children aged 3 to 8. It consists of two volumes: "Atomic Transformation: The Power of Nuclear Energy" and "Where Are the Elements: I Come from the Stars". In terms of design, it features hardcover binding, large illustrations, and matte coated paper, ensuring both comfort and durability during reading, while also stimulating children's curiosity through visually striking images. In terms of content, the books adopt an innovative "microscopic-macroscopic" dual perspective narrative structure, transforming abstract scientific concepts into concrete expressions that children can understand. 

The awarding of this book is an important recognition of popular science creation and science communication work. We look forward to sowing the seeds of scientific exploration in children's hearts through this entertaining and educational approach, laying a foundation for their future interdisciplinary learning and improvement of scientific literacy.

The update of the Essential Science Indicators (ESI) database in November 2025 shows that in the internationally renowned Journal IEEE Internet of Things Journal (ranked in the 1st zone of the Chinese Academy of Sciences), The paper "Geometrized task scheduling and adaptive resource allocation for large-scale edge computing in smart cities" published in IF=8.9 cities has been selected as an ESI highly cited paper.

Edge computing is vital in developing smart cities by providing on-site computational resources to support the surging Internet of Things demands. However, the distributed nature of edge nodes and large scale of tasks distributed in expansive urban spaces challenge task scheduling and resource allocation. In this article, a novel framework is developed to achieve efficient task scheduling (assignment and offloading) and resource allocation for large-scale edge computing in both wired and wireless smart-city applications. To overcome overparameterization in existing optimization-based heuristic algorithms, the geometrized task scheduling problem is addressed by transforming the assignment of clustered tasks into a regional partition problem in a 2-D graph and applying a Tetris-like task offloading strategy for edge-cloud cooperation. These approaches avoid combinatorial explosion and NP-hardness, and the regional partition problem is solved by multiplicative weighted Voronoi diagrams with polynomial computational complexity. Furthermore, an adaptive resource allocation algorithm is proposed to overcome the dynamic, uncertain, and highly concurrent task requests. An online learning algorithm is adopted to adjust the sliding window length according to the evolving conditions. Comparison results show that the proposed framework significantly reduces the average task deadline violation rate, i.e., up to 4.72% of (more than 20 times better than) those using the other schemes, especially when handling large-scale workloads.

Note: ESI highly cited papers refer to academic papers published in the past ten years and ranked in the top 1% of global citations in the same discipline. They can provide references for cutting-edge research in the discipline and can be used in the scientific research evaluation system.

On the afternoon of November 14th, Professor Mao Liang, the dean of the School of Environmental and Biological Engineering at Nanjing University of Science and Technology and a recipient of the National Science Fund for Distinguished Young Scholars, was invited by me to give an academic report titled "Ecological Risks, Mechanisms of Effects and Pollution Control of Typical Radionuclides in the Ocean" in our college. 

With the global application of nuclear energy and the influence of historical nuclear activities, the discharge of radionuclides into the sea and their ecological risks have increasingly drawn attention. The incident of Japan's discharge of nuclear wastewater from Fukushima has made this issue a global focus. Professor Mao Liang systematically introduced the tracking of the distribution, migration, and transformation of radionuclides in multi-phase environments such as seawater and sediments based on a radionuclide analysis platform. He also delved into the kinetics of radionuclide absorption, enrichment, distribution, and excretion in marine organisms (from primary producers to top consumers), revealing the toxic effects at the cellular and molecular levels. Additionally, he combined his team's research achievements in enzyme catalysis (such as lignin peroxidase and laccase) for degrading organic pollutants and the transformation of nanomaterials through Fenton reactions to explore new pathways for controlling and remediating marine radionuclide pollution based on biocatalysis and advanced oxidation technologies, providing scientific basis and forward-looking ideas for the management of marine radioactive risks. 

Note: Professor Mao Liang has long been engaged in research in the field of environmental chemistry. He has published over a hundred papers in journals such as Nature Sustainability, Angewandte Chemie International Edition, National Science Review, National Science Open, ACS Nano, and Environmental Science & Technology. He has received numerous awards including the First Prize of Natural Science of Jiangsu Province and the Second Prize of Natural Science of the Ministry of Education. He also serves as an expert reviewer for multiple national research projects and as an editorial board member for several academic journals.
