An axiomatisation for the multi-modal logic of knowledge and linear time LTK
No full textThe paper aims at providing the multi-modal propositional logic LTK with a sound and complete axiomatisation. This logic combines temporal and epistemic operators and focuses on m odeling the behaviour of a set of agents operating in a system on the background of a temporal framework. Time is represented as linear and discrete, whereas knowledge is modeled as an S5-like modality. A further modal operator intended to represent environment knowledge is added to the system in order to achieve the expressive power sufficient to describe the piece of information available to the agents at each moment in the flow of time

The functional state of athletes who have undergone coronavirus infection (COVID-19)
No full textThis study aimed to investigate the energy supply of athletes, who had a mild form of coronavirus infection (COVID-19) under cycling ergometric load (CEL) to substantiate the timing of recovery, as well as to determine the volume and intensity of physical activity. Eighty-seven athletes aged from 18 to 28 years old, involved in cyclic sports, were examined. Group I consisted of 52 athletes with COVID-19, and group II consisted of 37 healthy self-isolating athletes. In addition to the comprehensive examination, the tested athletes underwent special examinations: the study of diagnostic material using methods of nucleic acid amplification, spirography and spiroergometry, electrocardiography (ECG), and CEL. The results of athletes from both groups did not differ significantly (p > 0.5) in the 1st, 2nd, and 3rd examinations. The second examination revealed a discrepancy between functional reserves and the load performed, as evidenced by the difference in the recovery rate of most indicators, the results of the third examination in the long-term period (6 months) showed that the athletes of the first group did not have any violations of the parameters of the respiratory function (RF) and cardiovascular system at rest, after performing CEL, as well as in the recovery period. The results suggest that the full resumption of training loads and participation in competitions are possible only with the complete normalization of the functional state of the cardiorespiratory system. The most informative indicators are: minute ventilation (V ̇E), heart rate (HR), oxygen pulse (OP), and coefficient of oxygen utilization (COU)
Variational principles of micromagnetics revisited
No full textWe revisit the basic variational formulation of the minimization problem associated with the micromagnetic energy, with an emphasis on the treatment of the stray field contribution to the energy, which is intrinsically nonlocal. Under minimal assumptions, we establish three distinct variational principles for the stray field energy: a minimax principle involving magnetic scalar potential and two minimization principles involving magnetic vector potential. We then apply our formulations to the dimension reduction problem for thin ferromagnetic shells of arbitrary shapes

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Specifics of functioning of the market socialism in Belarus
No full textBělorusko je zemí, která má současně nejdéle úřadujícího prezidenta v Evropě a jako jediná v Evropě otevřeně buduje pro 21. století nestandardní ekonomický model tržního socialismu. Proto cílem této práce je zjistit, zda v Bělorusku opravdu tento model v současnosti převládá a zda je efektivní. Pokud ano/ne, proč? První kapitola se zabývá rešerší literatury, vysvětlením pojmu tržního socialismu a metodologií. Druhá kapitola je věnována analýze specifik fungování běloruské ekonomiky – vývoje základních makroekonomických ukazatelů, určitých sektorů hospodářství a zhodnocení mezinárodního obchodního postavení Běloruska. Třetí kapitola se zabývá posouzením efektivity tržního socialismu v Bělorusku z ekonomického a sociálního hledisek a analyzuje závislost běloruské ekonomiky na ruské. Tato práce rozšiřuje stav poznání o běloruském tržním socialismu.Belarus is the country that has the longest serving president in Europe and is the only one in Europe that is openly building a non-standard 21st century economic model of market socialism. Therefore, the aim of this thesis is to find out whether this model really prevails in Belarus now and whether it is effective. If yes/no, why? The first chapter deals with literature research, explanation of the concept of market socialism and methodology. The second chapter is devoted to the analysis of the specifics of the functioning of the Belarusian economy – the development of basic macroeconomic indicators, certain sectors of the economy and the evaluation of the international trade position of Belarus. The third chapter deals with the assessment of the effectiveness of market socialism in Belarus from economic and social points of view and analyzes the dependence of the Belarusian economy on the Russian one. This thesis expands the state of knowledge about Belarusian market socialism
