According to the latest data released by Clarivate’s Essential Science Indicators (ESI) database in September this year, the paper entitled "Digital disaster prevention for ocean engineering: Current progress and future directions", published in *Ocean Engineering* (a Q1 Top journal, IF = 6.3), has been selected as an ESI Highly Cited Paper.

This study addresses the risks of natural hazard-triggered technological accidents (Natech) intensified by the increasing frequency of typhoons and other extreme climate events, and systematically synthesizes recent progress in digital disaster prevention for ocean engineering under climate extremes. Focusing on three core areas—disaster-inducing factor identification, disaster mechanism modeling, and structural safety assessment—the paper summarizes the integration of physics-based numerical modeling, data-driven simulation, and system dynamics, and reviews the applications of digital twins, machine learning, and deep learning in scenario-based risk analysis, safety evaluation, and early-warning systems, with particular emphasis on offshore wind farms. Building upon this framework, the study proposes a forward-looking digital technology system that integrates environmental sensing, interpretable modeling, intelligent prediction and warning, and resilience-oriented decision support, paving the way toward more adaptive, predictive, and resilient safety management in ocean engineering.

Note: ESI Highly Cited Papers refer to papers published within the last ten years that rank in the top 1% globally by citation frequency within their respective subject fields. ESI Highly Cited Papers have now become one of the important indicators for measuring the academic influence of a university.

The paper "Fine-tuning vision foundation model for crack segmentation in civil infrastructures" has received over 100 citations on Google Scholar. It was published in May 2024 and achieved over 100 citations within just over two year, which is the fastest rate of citation breakthrough to date.

The rapid growth in citations closely reflects the broader trend of intelligent transformation in civil engineering. Traditional vision-based detection models trained on small datasets commonly suffer from limited generalization and poor adaptability to complex working conditions, which has constrained the large-scale application of intelligent inspection technologies in engineering practice. This study introduced a vision foundation model for crack segmentation and adapted it through parameter-efficient fine-tuning, effectively addressing these bottlenecks and providing a technical paradigm that can be directly adopted by related research.

The techniques adopted in the paper can also be extended to segment other types of structural defects, such as earthquake damage segmentation, rebar corrosion segmentation, and structural water seepage identification, gradually covering various inspection needs in structural health monitoring (SHM). Building on this technical framework, the team will carry out further exploration to advance the deployment of AI technologies in front-line engineering inspection and maintenance, providing strong support for the intelligent management of civil infrastructure.

The paper "Beyond annual dose: Assessing lifetime cancer risk from dietary radiocesium exposure and public risk-perception gaps in Japan" has been published in Environment International.

Radiocesium in food poses an ongoing challenge in environmental health risk assessment. Annual dose compliance (1 mSv/year) is essential for radiological protection but may not reflect cumulative lifetime cancer risk (LCR) under chronic exposure or corresponding public risk perceptions. This study developed an integrated radiological risk assessment framework. Using a nationwide survey in Japan together with food-monitoring data on radiocesium concentrations, prefecture-level LCR and risk-perception gaps were estimated through multilevel regression with poststratification. The annual dietary radiation dose was well below the 1 mSv/year benchmark, while modeled mortality and morbidity LCRs remained above 10⁻⁵, ranging from 1.84×10⁻⁵ to 1.37×10⁻⁴ and from 2.70×10⁻⁵ to 2.02×10⁻⁴, respectively. The high-risk prefectures identified in spatial analyses, particularly in Tohoku, warrant prioritized monitoring. Agricultural products were the dominant exposure pathway, accounting for approximately 55.0–64.5% of the estimated LCR. Estimated risk tended to exceed perceived risk in northern Japan, indicating a need for proactive risk control, whereas perceived risk tended to exceed estimated risk in central Japan, suggesting a greater need for targeted communication. By considering the LCR alongside annual dose metrics, this framework supports region-specific monitoring and risk communication.

On September 1, Dr. Lin Jiarui, Associate Researcher and Director of the Digital Construction Teaching Laboratory at Tsinghua University, was invited to our institute to deliver an academic lecture titled "Key Technologies for Intelligent Engineering Design Based on BIM and Development of Independent Software."

Engineering design is a critical stage that significantly influences construction quality and performance. Enhancing design quality has long been a focal point in the engineering field. In his talk, Dr. Lin shared his team's latest research advances in intelligent BIM-based design, including modular BIM generation, AI-enhanced design simulation, the QwenBIM large model, intelligent BIM review, and defect repair technologies, along with their practical applications. Additionally, he discussed progress in developing independent BIM software through case studies on three-dimensional structural design for offshore fixed platforms, exploring integrated solutions for intelligent engineering design. The presentation, both cutting-edge and practical, featured rich real-world examples and sparked enthusiastic discussions and in-depth exchanges among faculty and students.

Note: Dr. Lin Jiarui has long been engaged in research on intelligent drawing review, intelligent inspection, digital twins, and large-scale engineering models. He has led and participated in multiple national-level projects, including those funded by the National Natural Science Foundation of China and the Key R&D Program. He has published over 150 academic papers, co-authored nine industry and local standards, and holds more than 30 authorized patents and software copyrights. He has been selected for the China Association for Science and Technology’s “Young Talent Support Program,” and has received numerous awards, including a Gold Medal at the Geneva International Invention Exhibition, the Champion Award at the bSI openBIM Competition, the First Prize of Huaxia Construction Science and Technology, the Special Award for Scientific and Technological Progress from the Yellow River Conservancy Commission, the First Prize for Teaching Achievements at Tsinghua University, and Tsinghua University’s “Outstanding Teacher and Friend” Award.
