HSE Researchers Show How Congenital Motor Disorders Affect Brain Development
Researchers from HSE University’s Institute for Cognitive Neuroscience have synthesised the findings of their previous studies on brain development in children with obstetric brachial plexus palsy and arthrogryposis. Their analysis shows that impaired motor function in early childhood not only limits children’s motor experience but also affects memory, categorical thinking, and information processing. The study has been published in Frontiers in Psychology.

Window into the Body: Scientists Develop Neural Network to Detect Risk of 15 Diseases from Retinal Images
Russian universities, with the participation of HSE University, Sber, and Z-union, have developed a neural network that can simultaneously assess the risk of 15 types of pathology from retinal photographs, including not only eye diseases but also cardiovascular conditions. The AI system can help clinicians detect potentially concerning changes at an early stage, identify signs reflecting the condition of retinal blood vessels, and determine whether a patient may need further examination. The paper has been published in Frontiers in Medicine.

'We Did Not Limit the Time for Questions'
The International Laboratory for Supercomputer Atomistic Modelling and Multi-Scale Analysis at HSE University held a major conference on molecular dynamics. Participants had the opportunity to attend all the presentations, while speakers were given as much time as they needed to answer questions. The HSE News Service interviewed Grigory Smirnov, Head of the Laboratory, and Genri Norman, Chief Research Fellow, about the conference preparations and the discussions it generated.

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) ...

О возможности восстановления отрезков сообщения по информации о значениях исходных символов
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 ...
