Researchers at the HSE University AI Research Centre and Faculty of Computer Science have proposed a novel algorithm for detecting structural changes in time series. The method uses a neural network to compare various segments of a series, enabling rapid detection of changes in its behaviour. The results of their work have been presented at the 26th International Conference on Artificial Intelligence and Statistics— AISTATS (A*).

Researchers at the HSE Faculty of Economic Sciences have studied the relationship between the changes in the bitcoin prices and the media attention to this cryptocurrency. The researchers examined the mentions of bitcoin in the media between 2017 and 2021 and built a mathematical model that revealed the strong relationship between media attention and bitcoin prices. The study was published in the Applied Stochastic Models in Business and Industry journal.

A group of scientists from the HSE Faculty of Computer Science has conducted a study on the ability of neural networks to detect humour. It turns out that for more reliable recognition, it’s necessary to change the approach to creating datasets on which neural networks are trained. The scientists presented these results at one of the world's most important conferences on natural language processing — EMNLP 2023. 

Experts at HSE University and Lomonosov Moscow State University examined the available data on Moscow's walkability and found the central and south-western parts of the city to be more walkable than others. However, the eastern and south-eastern areas are in need of improvements to make them more pedestrian-friendly. The study has been published in Cities.

In a ground-breaking experiment, HSE MIEM researchers subjected Lavsan (polyethylene terepfthalate, polyester) and Kapton (polypiromellitimide, polyimide) polymers, commonly used in space technology, to ionising radiation for durations ranging from microseconds to several hours at temperatures of -170°C and +20°C, while comparing their electrical conductivity under extreme conditions. The study reveals that at -170°C, Kapton's conductivity is ten times lower than at +20°C. These findings can assist engineers in developing more effective protection for spacecraft against static discharges induced by ionising radiation. The study has been published in Journal of Applied Physics.

Across the globe, countries are witnessing dramatic shifts in the relative proportions of younger and older generations in their demographic makeup. Even in African states, signs of an emerging demographic decline are becoming evident. By 2050, two thirds of people aged 65 and over will be living in low- and middle-income countries. While an ageing population poses a significant challenge to national economies, it can also serve as an impetus for development, especially in the realm of technology. What is the extent of global population ageing, what challenges arise in this context, and whether humanity is capable of addressing them are some of the key questions, explored by IQ.HSE, based on a paper published in Sociological Journal by Leonid Grinin, Anton Grinin, and Andrey Korotayev at the HSE Centre for Stability and Risk Analysis.

The history of the invention of telephony reads like a captivating detective novel, but even more intriguing are the events that contributed to the worldwide adoption of this technology. In this series of columns on IQ.HSE, Anton Basov, HSE Faculty of Computer Science editor, discusses how telephones have become an integral part of our everyday life. The final episode of the series recounts how men were unable to cope with telephone operator jobs and were replaced by tall and polite young women. However, as telephone networks expanded, the role of the intermediary became unproductive, eventually rendering the switchboard operator profession obsolete due to automation—not the first nor the last time such a thing has happened. As for Alexander Graham Bell, he used the earnings from inventing the telephone to promote science, educate people about the world around us, and pursue new inventions.

Researchers at HSE University and George Mason University have investigated the sustainability of prospective international agreements on solar geoengineering. The authors have proposed a scheme in which payments flow from affluent nations to less wealthy ones; an arrangement which sets their proposal apart from traditional systems. The proposed model aims to dissuade more vulnerable countries from excessive use of the prevalent geoengineering method by providing compensation for the potential damage they may incur and supporting their adaptation to climate change. The paper has been published in Environmental and Resource Economics.

The history of the invention of telephony reads like a captivating detective novel, but even more intriguing are the events that contributed to the worldwide adoption of this technology. In this series of columns on IQ.HSE, Anton Basov, HSE Faculty of Computer Science editor, discusses how telephones have become an integral part of our everyday life. The ninth episode of the series explores the development of the first long-distance, interstate, and transatlantic telephone lines, which suddenly made people thousands of kilometres away feel as close as if they were in the same room together.

A team of researchers, including scientists from HSE University, have investigated the influence of human movement on the propagation of 6G signals. Within a range of up to 10 metres, the signal attenuation is comparatively minor, yet brief connection failures may still occur. Based on the study findings, a blockage detection algorithm has been developed to account for both signal attenuation and interruptions. The gaming industry is likely to derive the greatest benefits from this discovery. A paper with the study findings has been published in Computer Communications.
