In recent years, the convergence of computational methods and artificial intelligence (AI) has revolutionized various domains across science, engineering, and industry. This special issue aims to explore the exciting advancements, potential, and challenges in the field of computational methods enhanced by artificial intelligence. By harnessing the power of intelligent algorithms, researchers have unlocked new frontiers in problem-solving and decision-making, enabling innovative solutions for complex and large-scale problems. Computational methods have long been used to model and analyze real-world phenomena, ranging from physical processes to social dynamics. However, the advent of AI techniques, such as machine learning, deep learning, and natural language processing, has introduced a new paradigm, empowering computational methods with enhanced problem-solving capabilities. These intelligent algorithms can process vast amounts of data, extract meaningful patterns, and make accurate predictions, thus augmenting the traditional computational methods with unprecedented efficiency and accuracy.
Ultrafast electron microscopy (UEM) combines modern electron microscopy with pump-probe technique, which enables ultrafast imaging, diffraction and electron-spectroscopy with nanometer-femtosecond spatiotemporal resolution. The unique advantages of UEM enable powerful capabilities in the study of dynamic phenomena in materials, nano-systems and biology. In the last decades, the application of UEM in the research of non-equilibrium state including structural dynamics, magnetic dynamics, and other light-matter interaction phenomena brings new vision to the nature of multi-body interaction in materials and nano-systems. In addition, UEM has exhibited great application in the field of nano-photonics and electron optics based on the photon-induced near field microscopy (PINEM) effect, a phenomenon of quantum interaction between free electrons and optical field mediated by medium. The imaging of surface plasma polariton, band structure measurement of optical microcavities, electron acceleration, electron pulse compression and many other fascinating researches have been realized in UEM. Furthermore, with the great progresses in generation of attosecond optical pulses in the past decade (awarded the Nobel Prize in Physics in 2023), several strategies for achieving attosecond electron microscopy have been proposed and some of them have even been successfully demonstrated recently, providing an unprecedented powerful tool for study light-matter interactions on the nanometer or sub-nanometer spatial scale within a single or few optical circles.
The development and application of UEM are still fast expanding. The scope of this focus issue in Frontiers of Physics would cover the recent development of UEM and the novel applications in many scopes. We do hope that the issue will form a broad overview of the current state of this cutting edge field.
We are looking for high profile scientists from China and overseas to contribute Review, Topical Review, View & Perspective, or Research Article in the foresaid areas. Please feel free to choose a striking topic that best fits the issue. Co-authorship is welcome. There is no strict length limit for each article, and for each review at least 15 pages length is highly expected.
The sample article (TEX template) can be downloaded via http://journal.hep.com.cn/fop/EN/column/column15258.shtml and the new manuscript can be submitted online through http://mc.manuscriptcentral.com/fop. A copy of the volume will be mailed to all participants.

The 10th International Bridge and Tunnel Technology Conference & “Belt and Road Initiative” Transport Infrastructure Forum was held in Shanghai, China on 13-14, September 2022. With the theme of Promoting Innovative Development and Building High-quality Projects, the conference focused on the development of China’s infrastructure construction since the 18th CPC Congress and the construction and management experience of Belt and Road Initiative transportation infrastructure. The conference contains quality academic reporting, strategic frontiers and topics discussion, excellent report collecting, tech innovation exhibition and major engineering tours, which make a thorough summary on the major achievement and experience of bridges, tunnels and other basic infrastructure in domestic transport, hydraulic engineering, municipal engineering, and national defense construction. More than 30 domestic and foreign academicians, 80 scholars attended the meeting online and offline and gave presentations.
In view of a number of high-quality presentations delivered at the conference, the suggestion of organizing a special issue on “Technology Developments in Bridge and Tunnel Technology” in Frontiers of Structural and Civil Engineering (FSCE) was proposed by both the organizer and participants, and was positively responded by Prof. Junzhi Cui, Editor-in-Chief of FSCE. This special issue features a total of 5 interesting and good quality papers. They papers are “Full-scale site evaluation of ventilation expressway embankments underlain by warm permafrost along the Gonghe−Yushu Expressway” by Wang et al., “Preparation, with graphene, of novel biomimetic self-healing microcapsules with high thermal stability and conductivity” by Wang et al., “An innovative structure of open ribbed steel-UHPC composite deck” by Sun et al., “Technology for tunnel construction through high-pressure and deeply buried super-high-temperature fault zones with large water surges” by Li et al., “Eigenfrequency analysis of bridges using a smartphone and a novel low-cost accelerometer prototype” by Xia et al. All papers were selected, revised, and eventually accepted for publication in this international journal by rigorous peer review. The Guest Editors of this special issue are grateful to the authors for their contributed papers and to the reviewers for providing good-quality and timely reviews.
