RUDN University professor spoke at a workshop on mathematical modeling in biology and medicine in Italy
Professor Volpert spoke on the topic “Mathematical modeling of respiratory viral infections”.
“The report is devoted to recent work on mathematical modeling of viral infections from the point of view of their spread through cell culture and body tissues. It has been shown that the infection spreads in cell culture as a reaction-diffusion wave, for which the spread rate and viral load can be determined both analytically and numerically,” Vitaly Volpert, Director of the Interdisciplinary Scientific Center for Mathematical Modeling in Biomedicine, RUDN.
Professor Wolpert studied the competition of two variants of the virus in the same cell culture and showed that the variant with a higher individual wave speed outperforms the other and destroys it. This approach is applied to the Delta and Omicron variants of SARS-CoV-2 infection in human epithelial and lung cell cultures, allowing the infectivity and virulence of each variant to be characterized and compared.
Other presentations include:
- Adelia Sequeira (Portugal) reviewed mathematical models and methods for studying blood flow in blood vessels;
- Raluk Eftimie (France) studied the influence of the immune response on the growth of a cancerous tumor. Particular attention has been paid to the role of different types of macrophages;
- Malay Banerjee and Samiran Ghosh (India) spoke about the mathematical modeling of epidemics in the application to COVID-19. They introduced a new class of distributed or point delay models;
- Leon Tinet (France) discussed the influence of inflammation on the development of Alzheimer’s disease.
At the workshop, the Beltrami Prize was awarded for outstanding achievements in scientific, pedagogical and organizational work. The winners were Honorary Doctor of RUDN University Willy Jaeger from Germany and Luigi Preziosi from Italy. Willy Jaeger gave an overview report on COVID-19. Luigi Preziosi’s lecture was devoted to the influence of mechanical stresses on the behavior of biological cells.
How to improve the environment in big cities? This question is asked by experts from different parts of the world. 130 ecologists from RUDN University and Bogor Agricultural University (Indonesia) discussed the sustainable development of megacities at the international scientific seminar “Urban Ecology”.
The XX International Congress “Blishchenkov Readings” was held at RUDN University. This year it was dedicated to the topic of international law in the context of global civilizational confrontation. The current state of the legal system was discussed by 355 scientists from 28 countries.
The conference “Political Science in a Changing World: New Practices and Theoretical Search”* started out at RUDN University. More than 600 political scientists from Venezuela, Egypt, Finland, Chad, Sweden and 20 other countries present scientific solutions to the challenges a globalizing society is facing. There are more than 70 events on the agenda of the conference organized by the Russian Political Science Association (RPSA).
