A novel method of hit time and hit position reconstruction in scintillator detectors is described. The method is based on comparison of detector signals with results stored in a library of ...synchronized model signals registered for a set of well-defined positions of scintillation points. The hit position is reconstructed as the one corresponding to the signal from the library which is most similar to the measurement signal. The time of the interaction is determined as a relative time between the measured signal and the most similar one in the library. A degree of similarity of measured and model signals is defined as the distance between points representing the measurement- and model-signal in the multi-dimensional measurement space. Novelty of the method lies also in the proposed way of synchronization of model signals enabling direct determination of the difference between time-of-flights (TOF) of annihilation quanta from the annihilation point to the detectors. The introduced method was validated using experimental data obtained by means of the double strip prototype of the J-PET detector and 22Na sodium isotope as a source of annihilation gamma quanta. The detector was built out from plastic scintillator strips with dimensions of 5mm×19mm×300mm, optically connected at both sides to photomultipliers, from which signals were sampled by means of the Serial Data Analyzer. Using the introduced method, the spatial and TOF resolution of about 1.3cm (σ) and 125ps (σ) were established, respectively.
This article presents the results of research, which set out to clarify the importance and role played by the concept of using A2/AD capabilities in the military strategy of the Russian Federation. ...Analysis and criticism of the literature were used to solve the research problems. In order to guide the research process, a hypothesis was formulated, assuming that the Russian concept of using A2/AD capabilities is an operationalisation of a broader military strategy for defeating the adversary, as well as an effective deterrence mechanism. The research process established that the Russian concept of using A2/AD capabilities is a theory and operational practice, a broader military strategy of achieving multi-domain superiority over the adversary by conducting strategic offensive operations. Integrating offensive and defensive operational capabilities plays a key role in this concept, which guarantees possession of the strategic initiative and maintenance of dominance in the international security environment and supports the idea of creating Russian spheres of influence. It also prompts NATO states to counter the supremacy of the Russian Federation.
This study focuses on the identification and explanation of the threats that the Russian Federation is creating against the Baltic States and their security implications. The research process ...established that the Russian Federation will destabilize the Baltic States and the regional security environment. Threats to the security of the Baltic States are a consequence of Russi an strategic thinking on the offensive use of military force. Serious military challenges to the Baltic States are posed by the Russian Federation's A2/AD multi-domain capabilities located in the Kaliningrad Oblast. The Russian Federation will also try to regain its influence by influencing below the measure short of war through political, economic and informational instruments.
This article presents the research results, which set out to explain the mechanisms leading to the achievement of dominance by the Russian Federation in the international security environment. In the ...research process, the systemic approach was applied. Analysis and criticism of the literature, non-participatory observation and case study elements were used to solve the research problems. As a result, it was determined that the theoretical basis for the Russian Federation's achievement of international dominance is the concept of new generation war. The model of the strategic influence of the Russian Federation is directed at the shaping of the security environment and includes the synchronisation of kinetic and non-kinetic measures, indirect and direct effects, the blurring of the boundaries between war and peace and the application of pressure and aggression. The Russian Federation achieves strategic dominance through asymmetry, chaos, reflexive control, and strategic deterrence. Armed forces provide a key role in asserting dominance, focused on conducting offensive activities and inflicting losses with conventional and nuclear weapons.
Public opinion was outraged by information that Pegasus technology, intended to combat terrorism and organized crime, was also used to combat the opposition, surveil political opponents, and ...influence the outcome of elections in some member states of the Council of Europe and the European Union. These organizations have undertaken studies of these situations and have formulated a number of recommendations to Member States, including Poland. The author analyzed these documents and suggests that even if they are only the so-called “soft law”, the dispositions contained therein should be consistently implemented in accordance with the values of democracy, the rule of law and the protection of human rights. Full implementation of these recommendations by Poland is necessary to improve its image among democratic European countries.
The Council of Europe plays a special role in promoting democracy, the rule of law and the protection of human rights. The events of recent years, and especially Russia’s aggression against Ukraine, ...have significantly changed the conditions for the implementation of the Council of Europe’s mission. The author analyzed, based on the resolution of the Parliamentary Assembly of the Council of Europe 2473 (2022) “Strengthening the role of the Council of Europe as a cornestone of the European political architecture”, the activities of the Council of Europe aimed at seeking its role in the emerging new political architecture of Europe. Russia’s aggression against Ukraine may create conditions for a new look at the opportunities offered by the Council of Europe for European development and create a climate for intensifying forms of cooperation between European international organizations in the event of new threats to European development.
The material independence of judges is one of the essential guarantees of their independence and, at the same time, the proper functioning of the judiciary. Of course, one should not conclude from ...this that there is a simple relationship between independence and the material status of judges, nor should one presume a general prohibition on reducing judicial salaries. Undoubtedly, however, commensurate remuneration is permanently linked to the question of judicial independence. The aim of this article is to analyze premises of the permissibility of “freezing” adjustment of judges’ salaries in the light of international legal standards. The article is based on a specific factual situation, as in 2023, that basic salary adjustment for judges of common courts in Poland was “frozen” for the third year in a row.
