Immunity to Chaos: How Personal Resources Help Us Cope with the Challenges of a Turbulent World
International conflicts, crises and digital overload—the modern world puts our minds to the test every day. Traditional psychology often focuses on the consequences: anxiety, depression, and psychosomatic disorders. But what if we looked at the problem differently—through the lens of the resources that prevent us from breaking down? Psychological immunity is precisely this set of resources. Alena Zolotareva and her group, Psychological Immunity as a Resource for Positive Functioning, are developing an integrative model of this phenomenon, adapting diagnostic tools and preparing for large-scale empirical research. Why do psychologists need to collaborate with medical professionals, and how could their research transform preventive care in clinics and corporations?

How to Assess Students Knowledge in the Age of AI
A researcher at HSE University has proposed a flowchart to help lecturers decide how to assess students who use artificial intelligence. It shows where the use of AI should be restricted and where it can be incorporated into the learning process. The article has been published in IT Professional.

‘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.

Joint Usage of Dynamic Sensitivity Control and Time Division Multiple Access in Dense 802.11ax Networks

P. 57–71.
Evgeny Khorov, Anton Kiryanov, Alexander Krotov, Gallo P., Garlisi D., Tinnirello I.

It is well known that in case of high density deployments, Wi-Fi networks suffer from serious performance impairments due to hidden and exposed nodes. The problem is explicitly considered by the IEEE 802.11ax developers in order to improve spectrum efficiency. In this paper, we propose and evaluate the joint usage of dynamic sensitivity control (DSC) and time division multiple access (TDMA) for improving the spectrum allocation among overlapping 802.11ax BSSs. To validate the solution, apart from simulation, we used a testbed based on the Wireless MAC Processor (WMP), a prototype of a programmable wireless card.

© 2020 IEEE.Non-orthogonal multiple access (NOMA) is a key technology for future wireless systems. Keeping the number of antennas on the devices unchanged, NOMA increases the spectral efficiency of the wireless system and raises the aggregated system throughput. For this reason, NOMA is a very attractive technology for implementation in future Wi-Fi standards that will ...

О выборе параметров окна ограниченного доступа в сенсорной сети IEEE 802.11ah
Юсупов Р., Krotov A., Khorov E., В кн.: Сборник статей конференции "Информационные технологии и системы" (ИТиС'15).: М.: ИППИ РАН, 2015. С. 8–25.
Изначально сети Wi-Fi были созданы для обеспечения беспроводного доступа к сети Интернет небольшому количеству устройств. Однако быстрый рост числа устройств, использующих сети Wi-Fi, привёл к возникновению сценариев, когда к одной беспроводной сети Wi-Fi может быть подключено большое число устройств. Для снижения конкуренции при доступе к каналу между этими устройствами, в стандарте IEEE 802.11ah предусмотрено несколько ...

Алгоритм динамического управления мощностью передачи и порогом определения занятости среды в плотных сетях Wi-Fi
Krotov A., Kiryanov A., В кн.: 40-я междисциплинарная школа-конференция "Информационные технологии и системы".: [б.и.], 2016. С. 1–13.
Разрабатываемый в настоящее время стандарт IEEE 802.11ax призван адаптировать Wi-Fi для обеспечения требований плотных сетей. Одной из ключевых компонент данного стандарта является механизм динамического управления мощностью передачи и порогом чувствительности приемника. Его использование позволяет существенно увеличить пропускную способность сети, но в то же время может привести к несправедливому разделению канальных ресурсов между устройствами. В данной ...
