Novel CaV1-xWxO3 (0.1 < x < 0.33) oxides with an orthorhombically distorted perovskite structure of GdFeO3 type have been synthesized. These compounds contain in B-position W+6 and V cations in an oxidation state between +4 (CaVO3) and +3 (x=0.33). C

A detailed study of the refraction of an ordinary wave in the magnetosphere of radio pulsars was carried out. For this, a consistent theory of the generation of secondary particles was constructed, which essentially takes into account the dependence

The 2010s witnessed intensified debates in international academia on the relationship between theory and forecast, but Russian scholarship remained detached from these discussions. This article intends to examine the contribution of theory to forecas

The rise of China constitutes a challenge for the U.S. hegemonic aspirations. However, Washington reacts to it rather belatedly and with restrain. Up until the mid-2020s, the United States did not consider the preventive use of force as a means to de

In the aftermath of the Cold War, both scholars and experts frequently questioned the political relevance of security alliances, given the declining intensity of armed conflicts and the decreasing probability of major interstate wars. However, the po

This paper describes the acceleration of high energies protons captured by electrostatic waves in the frame of jet arising in the area of instability of relativistic jet, where spiral structures are excited. The wave has a spatially heterogeneous str

In this paper, which is the second in a series of papers, we analyse what parameters can determine the width of the radio pulsar 'death valley' in the $P$-${\dot P}$ diagram. Using exact expression for the maximum potential drop, which can be realise

We propose the model of the global structure of the electromagnetic fields in the Fermi bubbles (FBs), which makes possible the proton regular acceleration up to ultra-high energies. The poloidal and the toroidal magnetic fields, as well as the radia
