‘Balkan Hospitality Opens Doors: Studying Dialects on the Verge of Extinction
You cannot study spoken dialects from books. Instead, you need to go to a village, seek out its elders, and earn the trust of local residents before you can record hours of spontaneous stories. This is how Natalia Muravleva, Associate Professor at the Faculty of Humanities, conducts her research. Her internship in Serbia continued her long-standing study of dialects spoken by Macedonian settlers. In this interview, she discusses how diaspora cultural centres help researchers reach informants, why native speakers need to be interviewed only in their own language (otherwise, as she puts it, they may 'break'), and how a single field season helped her finalise her monograph. She also shares warm memories of autumn in Belgrade and of colleagues with whom grammar can be discussed in three languages at once.

Scientists Train Neural Network to Generate Process Plans from 3D Models
Researchers at the HSE FCS AI and Digital Science Institute have developed CAD2TechSpec, a framework that converts 3D models of mechanical parts into machining process plans—step-by-step instructions for machine tools. The solution aims to reduce the time required for the design and preparation of technical process documentation in mechanical engineering, aircraft manufacturing, and other high-tech industries. The study findings have been published in PeerJ Computer Science.

Biologists Discover 'Molecular Fingerprint' of Preeclampsia
Researchers at HSE University employed a new method to model hypoxia in placental cells during pregnancies complicated by preeclampsia and identified molecular markers of tissue hypoxia. Since hypoxia is one of the key mechanisms underlying preeclampsia, these findings are important for a more accurate and timely diagnosis of the disease and for the development of effective treatment methods. The paper has been published in Placenta.

The difference relations and impossible differentials construction for the KB-256 algorithm

Прикладная дискретная математика. Приложение. 2022. Т. 15. С. 73–77.
Chukhno A., Курочкин А. В., Фомичев В. М.

In this paper, new results of the analysis of the KB 256-3 block cipher algorithm are outlined. We set up a difference relation with probability 1 for the six-round algorithm under study and propose a key recovery method using this difference relation for the nine-round KB 256-3 algorithm. We construct an impossible differential for the full-round algorithm.

In this paper differences with probability 1 were found for 6 and 7 rounds of KB-256 block cipher. Also using Biham’s et al. shrinking technique we find more than 1700 impossible differentials for the KB-256 cipher with number of rounds from 8 up to 18 (2 rounds more than in the original KB-256) ...

Зачастую, при оценке  надежности  алгоритмов блочного шифрования, возникают задачи, связанные с исследованием свойств и характеристик множеств подстановок.  Подстановки зачастую являются самостоятельными элементами итерационных преобразований соответствующих механизмов защиты. В этой связи изучение свойств подстановок, максимально усложняющих проведение процедуры дешифрования, приобретают особую практическую и теоретическую значимость.  С другой стороны, сам алгоритм блочного шифрования можно рассматривать как случайную ...

Possibility of Recovering Message Segments Based on Side Information about Original Characters
Malashina A., Doklady Mathematics 2024 Vol. 108 No. 2 P. S282–S292
To provide secure information exchange in communication channels, the correctness of the operation of the relevant information protection systems must be preliminary studied. The mathematical algorithms used in such systems are correct and can theoretically provide the correct statistical properties of the output stream compared to the input. However, at the stage of implementation (programming) ...

The statistical analysis of iterative block ciphers is carried out for detection of dependences of statistical properties of output sequence depending on number of rounds. It is reasonable to utilize source codes available in the Internet, but their integration into own programs is impeded by at least the following reasons. Firstly, different implementations have different ...
