Research & Expertise news at HSE University

Four-year, instead of five-year, degree programmes shave off a year of study, thus saving considerable time and money, and allowing graduates to find employment and build work experience earlier, which eventually translates into a higher salary. This raises the question of whether a fifth year of undergraduate studies brings any returns at all.

Moscow has kept its leading position on the Russian Innovational Scoreboard. The city demonstrates the highest level of economic, educational, and digital development. Second place goes to Saint Petersburg, and third place goes to the Republic of Tatarstan. The leaders also include the Tomsk Region, the Nizhny Novgorod Region, and the Moscow Region. These are the main results of the seventh issue of the Russian Innovational Scoreboard prepared by the Institute for Statistical Studies and Economics of Knowledge (ISSEK), HSE University.

Psycholinguists from the HSE Center for Language and Brain, in collaboration with researchers from the City University of New York and the University of Stuttgart, investigated how reading in Russian varies among different groups of readers. The authors used a novel method in bilingualism research — comparison of the eye-movement sequences (scanpaths) in adult native speakers of Russian, Russian-speaking children, and adult bilinguals with different levels of Russian proficiency. The results of the study were published in Reading Research Quarterly.

According to experts of the Digital Environment Law Institute of HSE University, Artificial Intelligence (AI) may soon become a participant of the legal decision-making process, and the AI system will be entrusted with authority. Therefore, the issue of liability for ‘automated decision making’ should be addressed. HSE experts presented a special report that evaluates whether AI designers should be liable for the automated systems they create and what actions the government can take to develop AI investment projects.

Professor Alexey Tameev of HSE MIEM, along with a team of colleagues, has proposed a calculation method to determine the optimal photoactive layer thickness which can maximize the power conversion efficiency of solar cells. Applicable for both polymer andperovskite solar cells, the method can become a milestone on the path from laboratory samples to solar cells made from new generation materials. The results of the research are covered in ‘A common optical approach to thickness optimization in polymer and perovskite solar cells’, an article published in Scientific Reports.

Professor Konstantin Arutyunov of the HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE), together with Chinese researchers, has developed a graphene-based mechanical resonator, in which coherent emission of sound energy quanta, or phonons, has been induced. Such devices, called phonon lasers, have wide potential for application in information processing, as well as classical and quantum sensing of materials. The study is published in the journal Optics express.

On Friday, June 11, UNESCO held a ceremony to launch its new UNESCO Science Report, which arrives at a crucial moment as countries reach the halfway mark of meeting the UN’s Sustainable Development Goals by 2030. The Report shows that, over the past five years, countries of all income levels have begun efforts to transition to economies that are both digital and green. At the ceremony, six of the Report’s authors provided overviews of trends in their regions. Representing the East European region was Professor Leonid Gokhberg, First Vice Rector of the HSE University and Director of the HSE Institute for Statistical Studies and Economics of Knowledge (ISSEK).

‘Another City: Mystical Stories of Perm’ — this is the title of a work by Nikita Matkin, a first-year student in the Master's programme ‘Digital Humanities’. It received an honourable mention in the Best Russian-Language Scientific and Popular Science Works Competition for HSE University employees in the ‘History of Art’ track. Nikita spoke with the News Service about the idea for the project, his studies at HSE University, and his love for his hometown.
