The aim of this paper was to identify the nature of hybrid threats posed by Russia in Bosnia and Herzegovina and, subsequently, to identify to what extent the Kremlin is successful in destabilising the political situation in this country. For this pu

The recognition of the autocephaly of the Ukrainian Orthodox Church (UOC) by the Ecumenical Patriarchate in 2019 sparked a debate in the Orthodox world about the legitimacy of such an act. In the present study, we aim to explain, through the concept

Role of Electron Inertia and Reconnection Dynamics in a Stressed X-point Collapse with a Guide-Field

In previous simulations of collisionless 2D magnetic reconnection it was consistently found that the term in the generalised Ohm's law that breaks the frozen-in condition is the divergence of the electron pressure tensor's non-gyrotropic components.

J. Graf von der Pahlen and D. Tsiklauri, Phys. Plas. 21, 060705 (2014), established that the generation of octupolar out-of-plane magnetic field structure in a stressed $X$-point collapse is due to ion currents. The field has a central region, compri

Magnetic X-point collapse is investigated using a 2.5D fully relativistic particle-in-cell simulation, with varying strengths of guide-field as well as open and closed boundary conditions. In the zero guide-field case we discover a new signature of H

Abstract The geometric series or niche preemption model is an elementary ecological model in biodiversity studies. The preemption parameter of this model is usually estimated by regression or iteratively by using May's equation. This article proposes

Catchments are complex systems, which require regular monitoring of hydro-chemical parameters in space and time to provide comprehensive datasets. These are needed to characterize catchment behavior on a local level, make future projections based on
