The National University of Management participated in the Beijing-Moscow teleconference on the topic "New Drivers and New Opportunities: Chinese and Russian Experts' Views on the Chinese Economy."

The event was timed to coincide with the meetings of the Chinese People's Political Consultative Conference (CPPCC) and the National People's Congress (NPC), which took place on March 4 and 5, respectively.

Fanis Sharipov, Director of the Center for Socioeconomic and Political Research at the State University of Management, spoke among the invited experts. In the audience were students from the State University of Management, who will be studying in China for two years in September as part of the dual-degree program "International Manufacturing Business."

The participants discussed the results of the past five-year period and forecasts for the implementation of China's 15th Five-Year Plan for Socioeconomic Development (2026-2030). They also examined in detail the logic of China's economic policy and development to facilitate the formation of an objective understanding of the Chinese economy by the international community.

In his speech, GUU representative Fanis Sharipov emphasized our university's long-standing cooperation with China in the fields of education and science.

"The first cooperation agreement between the National University of Management and the Harbin Institute of Technology, a prestigious institution not only in China but also globally, was signed back in 1986. Since 2014, our university has been implementing a dual-degree program for undergraduate and graduate students in International Manufacturing Business with the rapidly developing Ningbo University. In 2023, the Center for Socioeconomic and Political Research at the National University of Management was established to develop scientific and technical cooperation with universities and research organizations in China," noted Fanis Falikhovich.

In addition, the director of the Center for Socioeconomic and Political Research at the State University of Management praised the achievements of Chinese companies in the field of AI.

"The State Council of the People's Republic of China formulated a detailed plan for the modern development of next-generation AI back in July 2017. It explicitly stated its intention to make AI the primary driving force of industrial modernization and economic transformation, strengthening national defense, internal and external security, education, and medicine by 2025. And here we recall how, on January 27, 2025, a Chinese startup triggered a collapse in the stock prices of American IT companies. By early February of last year, the NASDAQ high-tech index had lost 3.5%, representing a loss of almost a trillion US dollars. For experts, the successes of Chinese research in artificial intelligence (AI) are the result of China's systematic, long-term efforts in this field, which we have repeatedly noted in our research papers and conference abstracts," concluded Fanis Sharipov.

Novosibirsk State University has launched a service for automatically creating audio versions of books from the digitized collection of the University's Scientific Library. The project is based on developments by the NSU Research Center for Artificial Intelligence (AI Center) and is currently undergoing testing. Following the successful completion of the pilot project, the technology is planned to be rolled out to other libraries.

At this stage, we are talking about converting books from the university press and materials posted in the electronic library into audio format, with the permission of the copyright holders—a total of about seven thousand titles.

The audio is generated by a neural network: the text is extracted from a PDF, pre-processed, and then an audio version is created. "In the future, we plan to convert all books available in the NSU e-library into audio format. Currently, this number is around 7,000," said Evgeny Pavlovsky, a leading researcher at the NSU Center for Artificial Intelligence and a PhD candidate in physics and mathematics. According to him, the service is not intended to completely replace traditional reading, but is being created as an alternative form of access to text.

"We don't create a voiceover that completely replicates the original. It's an additional way to work with the book. For mass use, it's important that the solution isn't resource-intensive: one book takes about half an hour of processor time, and we're talking about a 16-core processor, even without a graphics card," he explained.

The service is based on the Kappa framework, developed at the NSU AI Center. It is designed for managing datasets and artificial intelligence models, testing them, and evaluating them before implementing them in workflows. The framework allows for checking the correctness of models and reducing the risk of errors or so-called AI "hallucinations." In the new project, Kappa is used to prepare training data for voiceover and collect feedback on the quality of the results.

The first hundred books have already been read in pilot mode, and the team is now awaiting feedback from the library and users. Here's one of them. examples of the service's operationNSU emphasizes that the project is being considered a technological test. Once the technology itself and the mechanisms for interacting with the library have been refined, the service may be offered to other universities and public libraries through a partner platform or in other formats. According to the developers, in terms of computing resources, audio recording of the entire collection is possible within a month, but organizational preparation and verification of the audio recording results may take up to a year.

Alexander Dmitriev

The Saint Petersburg State University of Architecture and Civil Engineering has a new candidate of technical sciences. The degree was awarded to Alexander Dmitriev, Director of the Smart Labor Test Site and Assistant Professor in the Department of Technosphere Safety at the Faculty of Civil Engineering.

The defense took place on November 26, 2025, at the Volga Region State Technological University (Yoshkar-Ola). The dissertation council reviewed the work on the topic "Justification of the Parameters of Tractors with Wheeled and Tracked Drive for Low-Volume Logging."

The Path to Defense

According to Alexander Dmitriev, preparing for the defense was an important and challenging stage in his professional development: "It's impossible to prepare perfectly for such work—every dissertation committee member has their own opinions and questions. But I consider the defense a success: the questions were interesting, and I was able to answer them well."

Work on this topic took approximately five years—from the initial scientific ideas to the completed study and thesis defense. During this time, scientific articles were published, calculations were conducted, and experimental studies were conducted.

Relevance of the study

This dissertation addresses the pressing issue of the impact of logging equipment on soil cover. Today, approximately 85% of logging companies in Russia are small and medium-sized companies that lack the means to purchase expensive specialized equipment and primarily use agricultural tractors.

Such equipment, particularly those from the Minsk Tractor Plant, is widely used due to its affordability and ease of maintenance. However, in forested conditions—stumps, fallen trees, and deep snow—its maneuverability is reduced and the load on the soil increases, damaging the ecosystem.

Alexander Dmitriev developed a mathematical model of a wheeled-tracked propulsion system, which retains wheels at the front and installs a track module at the rear. Increasing the ground contact area allows for:

Reduce specific soil pressure; reduce environmental damage; improve equipment cross-country ability; and increase traction characteristics.

The theoretical calculations were confirmed by laboratory experiments using soil stamping tests. The study also provides a business case for the system's implementation: modernization requires minimal investment but can significantly improve the efficiency of small logging operations.

Prospects for implementation

The concept of a wheeled-tracked propulsion system is well-known worldwide, but its application in low-volume logging and comprehensive mathematical justification of its parameters have not previously been conducted. The developed model can serve as a basis for further research and practical implementation at enterprises in the industry.

The results of the dissertation are publicly available and can be used by companies for independent calculations and equipment modernization.

On the scientific path and mentorship

Alexander Dmitriev emphasizes that a supervisor plays a key role in scientific development. He expressed gratitude to his mentor, Doctor of Engineering Sciences Olga Kunitskaya, noting that the combination of professional support and personal motivation serves as the foundation for a successful defense.

Speaking about students and young researchers, he advises treating a dissertation as a long-term project that requires systematic work and patience: "The main thing is not to give up when you feel like putting it all off. It's part of the journey. It takes time, planning, and an understanding that it's a long process."

New professional opportunities

Alexander Dmitriev currently works as an assistant in the Department of Technosphere Safety at the Faculty of Construction at St. Petersburg State University of Architecture and Civil Engineering and heads the "Smart Labor" testing site. Earning his academic degree opens up new professional prospects and the opportunity to compete for higher positions.

The university staff congratulates Alexander Dmitriev on the successful defense of his dissertation and wishes him continued scientific achievements, the implementation of research projects, and new professional heights!

The 14th season of the CASE-IN International Engineering Championship, which is held with the support of the Presidential Platform, has begun. "Russia is a land of opportunity"This was announced on March 3 at a press conference at TASS. Schoolchildren, students, and young professionals will develop effective projects to ensure the full digitalization of leading industries, implement artificial intelligence, and digital twins. The best of them will receive preferential admissions to master's and doctoral programs, additional points on the Unified State Exam (USE), paid internships, and opportunities to launch and develop their careers.

This season of the championship is dedicated to the theme "Technologies of the Future." Artem Korolev, founder and co-chair of the CASE-IN organizing committee, notes: "The CASE-IN Championship today is more than just a competition, but an international ecosystem for the early identification of talent and the training of professionals ready for practical work. In the new season, participants will work on solutions focused on the digitalization of key industries, the implementation of artificial intelligence, and digital twins."

The competition will be held in three leagues: school, student, and young professionals. The Student League, which has the largest number of participants, will start first. The championship opening ceremony will take place simultaneously at several universities in different cities.

In the 14th season, the Student League includes 12 industry areas: architecture, design, construction and housing and public utilities; biotechnology; geological exploration; mining; mining machinery and equipment; metallurgy; petrochemistry; oil and gas; project engineering; thermal power engineering; digital automation; electric power engineering.

In-person selection rounds will be held at more than 60 universities, with students from over 200 participating. The in-person selection round at the Saint Petersburg State University of Architecture and Civil Engineering will take place on March 26.

Olga Petrova, Deputy Minister of Science and Higher Education of Russia, noted: "Educational institutions not only facilitate the competition but also provide participants with opportunities for further education and professional development. This season, 161 universities are providing prize winners and champions of the School League with extra points towards their Unified State Exam scores, and 36 universities are offering the best participants of the Student League preferential admission to master's and doctoral programs."

At SPbGASU, being a winner of the School League of the International Engineering Championship "CASE-IN" gives 5 additional points towards the results of the Unified State Exam.

Winners from previous years shared their experiences of participating in the championship. For example, Lyudmila Morshchakova, the 2022 champion in the Architecture, Design, Construction, and Housing and Utilities category, works as a leading process engineer at Metropolis in St. Petersburg. "Thanks to the case, participants develop skills essential for real-world project work: the ability to work in a team, publicly defend their decisions, and withstand a high pace and stress. These are the qualities that enable them to effectively solve problems when designing complex, unique projects," the young specialist admitted. "Participating in the championship was one of the key career decisions of my life. My advice to students is this: don't try to guess what answer the company wants to hear. There is no single right solution. Independent, well-reasoned ideas and genuine engagement are valued."

The championship is organized by the Nadezhnaya Smena Foundation, the "Russia – Land of Opportunities" Presidential Platform, the "Youth Forum of Mining Leaders" non-profit partnership, and AstraLogika LLC. The championship has been held since 2013 and brings together schoolchildren, students, and young professionals from Russia, the CIS, and BRICS countries. The project is part of the "Science of Winning" initiative and the plan for the Decade of Science and Technology in Russia (2022–2031).

Experience, friendship, adaptation: the student association "Tutor Force" turns 10 years old

Translation. Region: Russian Federation –

Source: Peter the Great St. Petersburg Polytechnic University –

An important disclaimer is at the bottom of this article.

For several years, the student activist team "Tutor Force" has been successfully and diligently assisting international students, immersing them in the Russian environment and facilitating their adaptation. In 2026, the group will celebrate its 10th anniversary. To celebrate this anniversary, a new inter-university project has been launched: "10th Anniversary of the Tutor Faculty."

The project focuses on mentoring and tutoring international students. It's a comprehensive initiative with multi-level activities and stages that will be implemented during the spring semester with the support of the Department of Youth Policy and the Graduate School of International Educational Programs (HSIEEP).

Project objectives:

Developing a mentoring system; creating a sustainable system for transferring experience and knowledge; enhancing the skills of activists necessary for working with foreign contingents; and ensuring long-term and stable adaptation work.

At the beginning of the new semester, the team announced the launch of the "Tutor School." During the recruitment process, international students from the Preparatory Faculty of the Higher School of International Education, the Humanities Institute (HI), and the Institute of Industrial Management, Economics, and Trade (IPMEIT) were briefed on the opportunities offered by the association.

The candidates completed interviews and attended introductory lectures, where they were able to get to know the team better and gain a practical understanding of how the group works. The final stage will involve developing and defending a team project.

As part of the "Tutor School," activists were assigned to academic groups of international students. Throughout February, introductory and organizational meetings were held between international students and their tutors, where they met and interacted with each other to establish a strong relationship throughout the semester. Each academic group will be offered informal meetings, excursions to the Polytechnic Museum, where they will learn about the university's history and traditions, and career-oriented campus tours to help them successfully build their future careers.

During the first stage, to boost motivation, support team spirit, and give association members the opportunity to develop, a joint training session was organized with the Youth Policy Department. Participants included Maxim Pasholikov, Vice Rector for Information, Youth Policy, and Security; Ivan Khlamov, Head of the Youth Policy Department; Pavel Nedelko, Assistant Vice Rector for International Affairs; Andrey Dolgirev, Director of the Center for Youth Trajectories; and Vladimir Migunov, Administrator of the Center for Youth Trajectories.

Everyone was delighted to see the leadership among their friends, get to know each other better, and simply have a pleasant and engaging evening. Participants discussed the community's development trajectories, the team's growth areas, shared the association's proudest moments, and reminisced about its major achievements over the past ten years.

"The strategic sessions format for working with communities was recently introduced, but it's already bearing fruit," emphasized Maxim Pasholikov. "This helps the students view their activities from the perspective of the community's leadership, as well as the university's perspective. Based on the sessions' results, it's important to establish the community's development vector and ambitions for the near future. The university creates an environment for the students' development and doesn't manage the communities; rather, it creates mechanisms for fostering mutually beneficial partnerships."

"For the tutor community, which is celebrating its tenth anniversary this year, it's crucial to align ourselves, building on our many years of experience, and identify new challenges and goals," noted Ivan Khlamov. "I'd like to point out that the community includes new members who have recently joined and offer ideas for development, as well as those who have already gone some distance and understand the importance of establishing a mission for sustainability in the future. The session's results showed a very strong engagement from the members—this means the community has a bright future."

"The strategy session for Tutor Force marks a new level," says Pavel Nedelko. "The session was attended by key university youth policy leaders, with whom the tutors were able to discuss their concerns in an open dialogue. The tutors were promised support, which should undoubtedly boost the students' ambitions."

"It's great that the student association leaders are open to us, and we have the opportunity to see how active our students are," shared Andrey Dolgirev. "The students care about how Polytechnic University is developing, and they do a lot to make us a better university. It's great that we can work on great projects together, offering advice, and sometimes adopting best practices from students. Yes, we have a lot to learn from them too! That's what meetings like these are for."

"I'm delighted by the genuine interest and commitment to growth not only among new and existing members of the association, but also among the university department heads, who not only provide us with key methodological support throughout the year but also actively participate in the community's life in a friendly manner. This inspires the activists themselves and helps us gain an outside perspective on our successes and shortcomings," added Gupta Vedant, a student from India and president of the Tutor Force association. "A strategy session can be considered successful if its participants draw at least one conclusion to reflect on, and if they know what to strive for. Reflection, along with team discussion, is essential—this is the key to success."

In February, tutors also held several events: a Russian conversation club, a Chinese New Year celebration, and Maslenitsa.

A whole semester lies ahead, during which activists will attend training sessions, participate in an inter-university conference, and travel to Kholomki.

The NSU Mountain Tourism Section built an igloo at the Eskimo City festival.

Mountain Tourism Section of Novosibirsk State University took part in the annual winter festival "Igloo-2026. Eskimo City," which took place in February on the beach "By the Sea of Ob." This year's event attracted a record number of participants—over 600 teams, including the NSU team.

Team leader and NSU graduate student Vsevolod Efremenko explained that participation in the festival has already become a tradition for the section:

"Firstly, because it's a wonderful way to relax outdoors, and we love that (even at -20°C). Secondly, you never know when you'll have to build an igloo. It's best not to lose that skill. Thirdly, it's already a tradition; it would be strange not to attend the festival when you participate every year," he explained.

According to Vsevolod, the 2026 festival featured particularly comfortable conditions and was likely the largest-scale event ever held:

"This year, the amount of snow allowed us to build an igloo right on the ice of the Ob Sea. We were also lucky with sunny, warm weather, so there were a lot of people, and they even built igloos in unmarked areas. The snow was perfect for igloo construction, both in terms of structure and thickness."

This year, the NSU team deliberately chose the format of a compact, yet high-quality snow house:

"This year we built a small igloo because we wanted to do everything properly and according to the rules. Next year we want to build a larger one, one that will accommodate overnight stays. I hope the weather will be just as favorable," Vsevolod Efremenko shared his plans.

He added that the team hopes to build a large igloo "for many people" if snow conditions are favorable again:

“Unfortunately, there are years when there is little of it and it is difficult to build something large,” he explained.

Team member Nika Kovaleva described the construction process in detail. First, the team determined the diameter of the future dwelling based on the height of the tallest member. Then, the children split into two groups: one cut snow bricks, the other erected the walls, fitting the blocks together. In the final stage, everyone worked together again, sealing cracks with snow debris and adding additional snow. The construction took about 3.5 hours.

According to Nika, the most difficult thing was to maintain the correct shape of the igloo – dome-shaped or spherical.

“We ended up with a shape that resembled an egg,” the participant said.

Despite this, the team successfully completed the project and was able to not only test the snow house's durability but also create a cozy atmosphere within it.

After completing the construction, the participants enjoyed tea and pancakes right inside the igloo, then went for a stroll through "Eskimo Town," checking out the other teams' homes. Nika notes that it was especially rewarding to see how creatively many of the participants decorated their snow homes:

"It was wonderful to see so many people interested in this event, and it's always a joy to see them put so much effort into decorating their igloos. The festival leaves a lasting impression, and even the fatigue from the strenuous physical work disappears."

The NSU Mountain Tourism Section plans to continue the tradition of participating in the Igloo Festival, combining practical skills development with active winter recreation and informal networking for students and alumni.

Scientists have obtained unique data on the behavior of plasma at the periphery of a thermonuclear facility.

Translation. Region: Russian Federation –

An important disclaimer is at the bottom of this article.

Scientists from Peter the Great St. Petersburg Polytechnic University and the A.F. Ioffe Physicotechnical Institute have conducted the world's first study of the electric field behavior and plasma rotation velocity during edge localized modes (ELMs)—fast, short bursts of activity that inevitably occur during the operation of fusion reactors. The researchers experimentally determined the nature of the redistribution of energy, current, and electric field in the edge plasma, which, in the worst case, can damage the reactor walls. Investigating the mechanisms of these processes is essential for the development of reliable fusion energy. The results were published in the prestigious journal Physics of Plasmas, the research was supported by a grant from the Russian Science Foundation.

In a tokamak, the plasma is confined by a magnetic field and resembles a very hot medium, constantly experiencing oscillations, flows, and instabilities. One of the most important instabilities is edge localized modes, or ELMs. For efficient fusion, the plasma in a tokamak must be in the so-called H-mode (enhanced confinement mode). In this state, an invisible barrier forms at the edge of the plasma, acting like a wall to trap the heat inside. However, due to the enormous pressure difference across this barrier, disruptions—edge localized modes—occur periodically. These can be compared to a safety valve: they periodically release excess energy and impurities, preventing the plasma from escalating out of control. However, if this valve is triggered too forcefully, the impact on the chamber walls can be devastating to the entire facility.

Modern approaches to plasma physics considered only large ELMs dangerous, while small ones were considered not only safe but also almost ideal for fusion plant operation: plasma confinement was good, and there were no destructive large bursts. Scientists from St. Petersburg Polytechnic University and the Ioffe Institute conducted experiments on the Globus-M2 spherical tokamak and, for the first time in the world, determined how peripheral localized modes profoundly restructure the entire peripheral plasma region.

Experiments have shown that during an ELM, the plasma temperature and density in the near-plasma region increase sharply, currents outside the plasma change noticeably, fast ions are transported and accelerated, suprathermal electrons are lost, and plasma filaments are formed. It has been shown that the plasma rotation velocity increases during an ELM, with the effect extending several centimeters into the plasma rather than being limited to a narrow layer where the ELM develops, as previously thought. And all of this occurs in microseconds, meaning it's extremely fast. Individually, small ELMs appear harmless, but together they create intense and complex dynamics at the plasma periphery. "Small ELMs are not simply weakened bursts, but an independent dynamic regime in which the plasma periphery operates according to its own rapid and complex laws," noted Arseny Tokarev, a research assistant at the Scientific Laboratory of Advanced Methods for Studying Spherical Tokamak Plasma at the Institute of Physics and Mechanics at St. Petersburg Polytechnic University.

The results of the measurements showed that the electron temperature in the boundary region during ELM increases up to 5 times, the concentration increases approximately 2 times, the plasma rotation speed increases by approximately 50% at a depth of up to several centimeters, fast ions are registered with an energy 6 keV higher than the injection energy, and filaments move at a speed of 3–10 km/s.

The practical significance of these results for the future of global fusion energy is enormous, as they provide a more realistic understanding of the stresses on the walls of fusion reactors. Future fusion reactors must operate continuously for long periods, rather than in short experimental pulses. Modes with small ELMs are considered prime candidates. Furthermore, unique data were obtained on the behavior of plasma parameters during ELMs, in particular, the rotation speed, which was measured for the first time in the world. This facilitates the transition from empirical selection of operating modes to deliberate control and reduces the risk of unexpected effects when scaling from experimental setups to reactors. The results will help make future fusion reactors not just operational, but reliable, predictable, and economically feasible, noted Alexander Yashin, head of the High-Temperature Plasma Diagnostics research laboratory at the Institute of Physics and Mechanics at St. Petersburg Polytechnic University.

The research was supported by grant No. 23-72-00024 from the Russian Science Foundation using the Federal Center for Collective Use "Materials Science and Diagnostics in Advanced Technologies" at the A.F. Ioffe Physical-Technical Institute, which includes the unique scientific facility "Spherical Tokamak Globus-M."
