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?

‘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.

Experimental Analysis of the Electrodynamic Characteristics of the Coaxial-Radial Line Type Slow-Wave Structures and Its Modifications

P. 1–4.
Presnyakov S., Kasatkin A., Kravchenko N., Mukhin S.

In this paper, we experimentally analyze the electrodynamic characteristics of a slow-wave structure (SWS) of the coaxial-radial line (CRL) type. Such SWSs are widely used in high-power traveling-wave tubes (TWTs) provide high output powers due to good heat removal, but have the limited amplified frequency band. For analysis, the resonance method and the electron probe method are used. Based on the results of the study, the possibility of using SRL to build a multibeam broadband TWT is evaluated. The assumption that the dispersion characteristic of the zero harmonic of the fundamental passband of the CRL is practically parallel to the wavelength axis in a wide range was experimentally confirmed.
