‘This Format Turned Each Presentation Into a Collaborative Effort to Assess the Robustness of the Study
On October 16, 2026, HSE ICEF hosted the Eighth International Conference on Applied Economics. Held fully on-site, the conference brought researchers from HSE University, the New Economic School, Wuhan University, and Shandong University together in Moscow. The programme was organised around three overarching themes— ‘Environment, Resources and Policy,’ ‘Migration, Labour, and Communication,’ and ‘Consumption, Behaviour, and Climate—offering an opportunity to see how similar economic mechanisms operate in China, Pakistan, the United States, and Russia.

‘I Always Conduct Research on Topics That Genuinely Matter to Me
Anastasiia Deeva studies the socio-economic consequences of excess weight in Russia. In an interview for the Young Scientists of HSE University project, she spoke about why beauty cannot be measured, her desire to write a novel, ‘Dostoevskian’ burnout, and working at the hotel where The Shining was filmed.

'Cultural Studies Seeks to Understand What Lies Beneath the Surface of Everyday Things'
Maxim Zhiganov has been exploring different aspects of sound for many years—first in relation to his native Perm and then on a broader, global scale. In this interview for the HSE Young Scientists project, he talks about sound maps, the special issue of the journal Logos, and why it is important to make the familiar less clear and obvious.

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) ...

А. Г. Малашина, Доклады Российской академии наук. Математика, информатика, процессы управления (ранее - Доклады Академии Наук. Математика) 2023 Т. 514 № 2 С. 138–149
В целях обеспечения защищенного информационного обмена в каналах связи необходимо предварительное исследование корректности работы соответствующих систем защиты информации. Несмотря на то что используемые в таких системах математические алгоритмы корректны и теоретически обеспечивают правильные статистические свойства выходного потока по сравнению с входным, на этапе реализации (программирования) данных алгоритмов защиты или на этапах сборки конечного оборудования (использования ...

Mathematical model for recovering discrete parts of a text message
Kulikova (Malashina) A., / Series rs.3.rs-595013 "Research Square". 2021.
The paper studies the procedure for restoring discreet segments of an unknown source message based on information about possible variants of each sign. An algorithm is proposed based on compiling dictionaries of appropriate lengths, searching for text sections with a total number of character variants that do not exceed a given boundary, and then iterating ...
