Koncepcja rozwiązania modelowego dla systemu bezpieczeństwa publicznego dużej aglomeracji miejskiej

The subject of this study is to present the concept of a model solution for the public security system of monocentric and polycentric agglomeration. Taking into account the security conditions of a large urban agglomeration, one universal scheme of police organization has been adopted. Its func-tioning on the basis of specific forms and methods to some extent limits the autonomy of police chiefs in shaping safety in accordance with the specificity and internal social and organizational conditions of the agglomeration. Among the available research methods, the participatory observation method was used in particular. Nevertheless, the basic scientific method for obtaining empirical data was a diagnostic survey. Furthermore, the article presents the opinion of police officers on the transfer of solutions from the Warsaw agglomeration to other agglomerations in Poland. The author’s conceptual proposal of a model solution for the public safety system of a large urban agglomeration was presented.

A universal scheme for the application of hazard protection measures, which can be comprehensive, has been developed. Praemonitus praemunitus – precautions should be taken.

The elusive promise of universal social protection: the case of the Greek general minimum income (GMI)

PurposeThe need to alleviate poverty and achieve the United Nations (UN) 2030 Sustainable Development Goals (SDGs) through Universal Social Protection (USP) mechanisms is a high priority for governments and international organisations (IOs). This paper focuses on the recent introduction of a general minimum income (GMI) in Greece, in the context of the international diffusion of governing expertise. It examines whether the “universal” scheme being implemented constitutes a paradigm shift likely to offer solutions to the country's previous fragmented and unjust welfare system, and to problems the society has faced since the 2010s depression.Design/methodology/approachThe paper uses critical grounded theory, with data gathering through iterative field observations and semi-structured interviews.FindingsResults highlight the elusiveness of USP normative promises: rather than enhancing people's effective freedoms to act as self-determining agents, USP pushes the poor to adapt to current degraded socio-economic conditions. Participation in the shadow economy is a structural feature of USP; it is implicitly tolerated insofar as it is regarded, in the words of the World Bank (WB), an “engine for growth”. This constitutes an institutional and governance challenge for the implementation and expansion of social welfare programmes and could compromise the 2030 SDGs Agenda.Originality/valueWhile research to date has examined the “modernisation” of the Greek welfare system in a national or comparative perspective, it adds to the literature by framing the study in the field of global social policy, shedding light on the discrepancies between internationally designed mechanisms and the normative aims of USP.

Engineering single-molecule fluorescence with asymmetric nano-antennas

As a powerful tool for studying molecular dynamics in bioscience, single-molecule fluorescence detection provides dynamical information buried in ensemble experiments. Fluorescence in the near-infrared (NIR) is particularly useful because it offers higher signal-to-noise ratio and increased penetration depth in tissue compared with visible fluorescence. The low quantum yield of most NIR fluorophores, however, makes the detection of single-molecule fluorescence difficult. Here, we use asymmetric plasmonic nano-antenna to enhance the fluorescence intensity of AIEE1000, a typical NIR dye, by a factor up to 405. The asymmetric nano-antenna achieve such an enhancement mainly by increasing the quantum yield (to ~80%) rather than the local field, which degrades the molecules’ photostability. Our coupled-mode-theory analysis reveals that the enhancements stem from resonance-matching between antenna and molecule and, more importantly, from optimizing the coupling between the near- and far-field modes with designer asymmetric structures. Our work provides a universal scheme for engineering single-molecule fluorescence in the near-infrared regime.

A universal scheme for robust self-testing in the prepare-and-measure scenario

We consider the problem of certification of arbitrary ensembles of pure states and projective measurements solely from the experimental statistics in the prepare-and-measure scenario assuming the upper bound on the dimension of the Hilbert space. To this aim, we propose a universal and intuitive scheme based on establishing perfect correlations between target states and suitably-chosen projective measurements. The method works in all finite dimensions and allows for robust certification of the overlaps between arbitrary preparation states and between the corresponding measurement operators. Finally, we prove that for qubits, our technique can be used to robustly self-test arbitrary configurations of pure quantum states and projective measurements. These results pave the way towards the practical application of the prepare-and-measure paradigm to certification of quantum devices.

PROSPECTS FOR THE DEPOSITS DEVELOPMENT IN OSSETIA

Goal. Substantiation of the ecological and economic efficiency of innovative technologies for the development of deposits of the Sadonsky ore cluster during the period of restoration of the lost industrial potential of the depressed region. Methods. Analysis of the theory and practice of mining, with priority given to the experience in the development of North Caucasian deposits. Laboratory experiment in the study of the properties of filling mixtures and options with different activation methods, including reagent leaching in a disintegrator. Mathematical and economic modeling of the efficiency of recycling tailings utilization at the cost of commercial products, taking into account the prevented environmental damage. Results. The information on the dynamics of mining and processing of ores from the Sadonsky deposits is presented. The results of studies of the properties of base concrete mixtures based on ore dressing tailings and local available components are systematized and generalized. The results of changes in the properties of hardening mixtures are given depending on the presence of metals in the tailings of enrichment with various activation options by alternative methods, including an innovative method of mechanochemical leaching in a disintegrator with electrochemically activated water. The equivalent of 1 kg of cement using binders from processing tailings has been determined. The advantages of mechanochemical activation of tailings in a disintegrator in comparison with the option of irrigation by irrigation using various reagents have been experimentally determined. A quantitative indicator of an increase in the strength of the compositions of hardening mixtures under equal conditions has been established. The efficiency of utilization of tailings and metallurgy has been determined as a set of effects of reducing the amount of environmental damage from storage of tailings, the cost of metals obtained during processing, raw materials for the construction industry and associated marketable products. The nomenclature of tailings processing products has been detailed. A model for determining the profit from processing tailings and metallurgy is recommended. A forecast is given at the level of engineering expertise of the prospects for tailings processing. The hardware diagram of the tailings disposal section is detailed. A universal scheme for the disposal of mining and processing waste was recommended. Conclusion. The prospects for the development of the deposits of the Sadonsky ore cluster depend on conversion to technologies with filling voids with solidifying mixtures and leaching of metals at the processing stages. The combined mining technology will reduce the output of tailings, strengthen the base of the construction industry, eliminate the need to build a second stage of tailings and improve the environment.

Immune-like procedure for functionality of the system of information security in automated data processing systems in the context of countering internal threats

The subject of this research is the system of creating mechanisms of information from internal threats in automated data processing systems similar to the mechanism of human immunity. The object of this research is the mechanism of human immunity and systems of ensuring information security in automated data processing systems. The goal of this work lies in the development of the universal scheme of functionality of the mechanism of human immunity against internal threats in form of the procedure, and develop on its basis the immune-like scheme for countering internal threats applicable to the systems of ensuring information security. Methodological research on the development of procedure for detecting internal threats in the mechanism of human immunity is carried out via the methods of systemic analysis in area of ensuring information security. Special attention is given to such aspects as consistency and adaptability of the mechanisms of human immunity applicable to the systems of ensuring information security. This article introduces the new solution to the task of adapting the universal scheme of functionality of the immune system in countering internal threats in the systems of ensuring information security based on the principle of demarcation of the elements to “known/alien” and implementation of the procedure to “destroy” threat, the so-called “Trogotcytosis” (“gnaw”). The developed procedures may serve as the basic schemes in further practical studies of the immune-like systems of ensuring informations security.

Measurement of the isobar heat capacity of fluids in the critical area by the method of flowing adiabatic calorimeter

With regard to the problem of refining the fundamental equations of state of hydrocarbons, the methodological and design features of the experimental measurement of the isobaric heat capacity in the critical region by the method of a flow adiabatic calorimeter are considered. The pressure measurement system has been improved by introducing a differential manometer into the measuring circuit, which made it possible not only to increase the accuracy of pressure determination, but also to implement a universal scheme of calorimetric experiment. The use of a universal scheme of the calorimetric experiment allows one to determine two values of the isobaric heat capacity at pressures that differ by the value of the pressure loss in the calorimeter. Such an approach in the critical region is relevant, since it makes it possible to quite simply and reliably determine the value of the derivative of the heat capacity with respect to pressure, which is used to estimate not only the error in assigning the value of heat capacity to pressure, but also the equilibrium conditions of the experiment in a flow-through calorimeter. The technique of determining and making a correction for the inhomogeneity of the supply wires of the differential thermocouple, for the throttling of the flow of matter in the calorimeter is considered. Correct relations are obtained for determining the average temperature of the measurement experiment for various methods of measuring the temperature and temperature difference in a flow-through calorimeter. The results of experimental measurements of the isobaric heat capacity of n-pentane in the critical region, obtained using the universal scheme of the calorimetric experiment, for n-pentane were measured on an isobar of 3.400 MPa (critical pressure 3.355 MPa), which is the closest to the critical point at practice of flow calorimetry

Shortcuts to Adiabaticity in Driven Open Quantum Systems: Balanced Gain and Loss and Non-Markovian Evolution

A universal scheme is introduced to speed up the dynamics of a driven open quantum system along a prescribed trajectory of interest. This framework generalizes counterdiabatic driving to open quantum processes. Shortcuts to adiabaticity designed in this fashion can be implemented in two alternative physical scenarios: one characterized by the presence of balanced gain and loss, the other involves non-Markovian dynamics with time-dependent Lindblad operators. As an illustration, we engineer superadiabatic cooling, heating, and isothermal strokes for a two-level system, and provide a protocol for the fast thermalization of a quantum oscillator.

ИСПОВЕДАЛЬНОСТЬ В ПОЭЗИИ ВЯЧЕСЛАВА ИВАНОВА: ПРЕДВАРИТЕЛЬНЫЕ ЗАМЕЧАНИЯ

The article traces parallels between some confessional situations in the poetry of Vyacheslav Ivanov and the Confessions of St. Augustine. The question is raised about the ability of Ivanov`s symbolism to reproduce the existential uncertainty (ignorance of the further path, the actual rejection of its foreshadowing by culture and intellectual experience), to which the confession should lead the subject, if s/he follows the principle of Augustine`s „transcende te ipsum”. When the state of confession is pre-established by a system of symbols with a „ready” meaning, it risks losing its uniqueness: the confession can be replaced by some universal „scheme” of confessionality, which happens in a number of the Ivanov`s poems. Thus, the article delineates one of the possible perspectives of the further study of the claimed topic.
