description: Parametric and structural uncertainties complicate the project management processes. The critical path is one of the pivotal parameters, which helps to control the project schedule and is used to determine the criticality of the tasks and activities that are the most decisive and should be treated during a project expediting or controlling. There may be a set of the critical paths in uncertain environment. Therefore, the main question is which of the critical paths to select. The aim of this paper is to answer to this question. We used Monte Carlo simulation to investigate the multiple critical paths. We revealed and explained several paradoxes that emerged as results of the multiple critical paths occurrence. They are inevitable late bias of the project duration under uncertainty, the tasks probability and their correlation effects, the impact of concurrent chains of the tasks on their criticality, multiplicity of the critical paths and especially multi-chain critical paths. We demonstrated that multiple critical paths are not negative effect. On the contrary, they play extraordinary useful role and are the reliable criterion of the project robustness and stability.

description: Information warfare is an integral part of the struggle between contemporary nations and alliances, making use of a variety of instruments of asymmetric warfare. The Russian Federation employs this type of approach very effectively to influence the minds of foreign decision-makers and populations in targeted countries. The information domain is equally important for Russia’s own domestic objectives of restoring national pride and integrity, as well as preserving trust in national leadership. Military manoeuvres play an important role in information warfare, provoking fear and uncertainty in other countries, while aiming to convince the Russian population to have faith in the special role their nation holds in the global order.

description: Solar power is currently a widely recognized energy source that has gained significant attention from numerous countries. Over time, two predominant solar technologies have emerged internationally: solar photovoltaics and solar thermal power. In the case of solar photovoltaics, sunlight is directly converted into electricity. However, despite advancements in thin-film solar photovoltaics, they still exhibit lower electricity output due to the uncontrollable and highly variable nature of rapidly changing weather conditions. Solar thermal power, on the other hand, harnesses solar heat in power plants to generate electricity. However, this type of power generation faces similar challenges. The lack of high-capacity thermal storage contributes to its inherent unpredictability and variability. In the coming years, the solar thermal power industry in Uzbekistan should prioritize harnessing the unique advantages offered by the combination of hybridization and thermal energy storage. With decreasing costs and the increasing adoption of renewable energies, solar thermal power plants have the capability to provide dispatchable power, making them highly suitable for a pivotal role in a future energy grid primarily powered by renewable sources.

description: Nuclear factor of activated T-cells 5 (NFAT5) is a transcription factor known for its role in osmotic stress adaptation in the renal inner medulla, due to the osmotic gradient that is generated between the renal cortex and renal inner medulla. However, its broader implications in kidney injury and chronic kidney disease (CKD) are less understood. Here we used two different Cre deleter mice (Ksp1.3-Cre and Aqp2-Cre) to generate tubule segment and even cell type-specific NFAT5-deficient mice and performed extensive gene expression profiling. In both Nfat5 knockout models, we observed massive changes in gene expression pattern, with heightened inflammatory responses and renal injury, culminating in renal fibrosis. Interestingly, inflammatory responses were much more prominent in the Aqp2Cre+/−Nfat5fl/fl mice that lack NFAT5 only in the collecting duct. By analyzing gene expression in the medullary and cortical regions of the kidney separately, we confirmed that the loss of NFAT5 results in kidney injury that extends beyond hypertonic areas. Renal injury correlates with the expression level of genes involved in inflammatory response, injury severity, and cytokine signaling. Thus, NFAT5 is essential not only for adapting to osmotic stress but also for its loss of function, which induces activation of inflammatory response and cytokine signaling that might affect regions with functional NFAT5 expression.

description: This study presents a robust approach to predicting solar irradiation in the challenging climatic conditions of Tomsk using LASSO regression, with a particular emphasis on interpretability and climatic variability. Two distinct models were developed: Model 1, integrating specific humidity at 2 meters, and Model 2, excluding this variable to assess the impact of a wider range of meteorological factors. The comprehensive meteorological dataset from NASA’s POWER database underpinned the analysis. The models' efficacy was demonstrated by impressive R-squared values: 0.843 for Model 1 and 0.813 for Model 2, indicating a substantial proportion of variance in solar irradiation was captured. Notably, Model 1's RMSE of 0.0353 and Model 2's RMSE of 0.0386 affirm the precision of the predictions. The study advances the predictive modeling of solar power output, offering valuable contributions to renewable energy forecasting literature and operational practices by providing a methodological framework that is both accurate and comprehensible, even amidst the complexities of extreme weather patterns.

description: Research has shown that the current entrepreneurial environment promotes the formation and growth of integrated interaction forms. These integrated relationships foster alignment among key stakeholders, including partners, consumers, employees, society, and government authorities, emphasizing the importance of social responsibility. A particularly pressing issue is the implementation of social responsibility through integrated forms as a community, necessitating further research to evaluate their impact on regional socio-economic development. Using statistical data and regression analysis, researchers developed a model to assess how regional employment and unemployment rates, alongside the inflation index, influence the effect of integration forms on socio-economic development. Normative fluctuations for unemployment (2%) and employment (7,5%) in the region were identified. The regression analysis resulted in the calculation of an indicator (IF_avg) - to measure the contribution of integrated forms to socio-economic development. This indicator enables the assessment of whether such forms positively impact regional development. Testing this approach on the construction company "Gefest" in the Odessa region demonstrated a positive impact, with a calculated result of 1,26%. While these findings provide initial insights, they are not without limitations. Future improvements could incorporate additional indicators such as investment volume, innovative activity levels, and labor productivity to refine the model and enhance its accuracy in evaluating the influence of integration forms.

description: The article considers the possibilities of solving interpolation and approximation problems using special types of functions, such as root polynomials and root fractional rational, and provides relevant examples. It is prove, that the use of root polynomial functions is especially effective for interpolation and approximation of numerical dependencies with a ravine data set, and the use of root fractional rational functions gives the best results for various data sets with a more rigid functional dependence. To solve the approximation problem, a new approximation by reference points is proposed and tested. With a small number of points in the data set for the approximation problem, equal to twenty or less, the convergence of the proposed method is usually guaranteed. In general, the proposed algorithms are very universal and can be easily adapted to any complex problems. All the proposed methods are implemented and tested in the newly developed computer software created in the Python programming language.

description: Following the collapse of the Soviet Union, Russia has been fuelling frozen conflicts in the South Caucasus region in order to promote instability and force security dilemmas as part of its geopolitical strategy in the former Soviet republics, geared towards maintaining its control over the post-Soviet space. Throughout the post-Cold War period, Russia has been actively involved in stirring up conflicts in the South Caucasus, sustaining interstate tensions and unsolvable security dilemmas by supporting Armenia against Azerbaijan, and the secessionist republics of Abkhazia and South Ossetia against Georgia, resulting in diminished regional cooperation and curtailing Euro-Atlantic integration. Russia’s geopolitical strategy often follows the principles of the Eurasianist ideology that has identified Russia as an alternative power to the West. Owing to that, Russia’s geostrategic ambitions in the South Caucasus regard the region as a critical battlefield in the status conflict between Russia and the West, with Russia actively pursuing these strategic ambitions by keeping the region in a constant state of destabilization through interstate security dilemmas and frozen conflicts.

description: The article investigates hot water production by cooling a photovoltaic panel in a PV device. For this purpose, a parallel-channel polycarbonate heat collector was installed on the back surface of the PVT. The results obtained based on mathematical modelling of PVT thermal parameters are presented in the article. Mathematical modelling was performed based on Comsol multiphysics 6.1 integrated software. In mathematical modelling, the dependence of thermal energy obtained from PVT on radiation intensity, temperature and speed of cooling water was studied. Mathematical modeling results were compared with experimental results. According to the results of mathematical modelling, the maximum value of PV surface temperature was 47.6oС in summer when the water speed was 0.001m/s. In the summer season, the results of the experiment conducted on the PVT device and mathematical modelling were compared. The results of experiments and mathematical modelling showed that the temperature of hot water difference by 2oС. It was determined that 41.4 liters of hot water per hour is obtained from the PVT device.

description: The active development of science and technology became the basis of significant changes, which provide for the rapid introduction of ICT in all spheres of economic relations and human life. Such innovations have led to a change in socio-economic activity, which today is defined by digital transformation. The development of the digital economy inevitably affects a person, the demands placed on his abilities, skills and knowledge. The hypothesis regarding the allocation of digital skills in the structure of human capital, the acquisition of which allows the effective use of new electronic services and ICT in work and everyday activities, is becoming dominant in the world. Therefore, we consider it relevant to study the essence and components of digital skills, which can become the basis for comparing their level in different countries. Accordingly, the purpose of this study was to reveal the theoretical and methodological foundations of digital skills and to find out the relationship between the level of digital skills of the population and the competitiveness of the country in the conditions of digitalization of its economy. To achieve the goal, several general scientific and specific methods of cognition were used, including analysis and synthesis, content analysis and the method of classification and analytical grouping, statistical method, economic forecasting. As a result of the study, it is proposed to distinguish the following components in the structure of digital skills: technical and computer skills, communication skills, security skills, media information and data analysis skills, and the ability to solve digital-based problems. It was revealed that the level of development of digital skills depends on the pace of development of the national economy, its competitiveness, the activity of implementation and dissemination of innovative activities. This assumption is confirmed by comparing DSGI (The Digital Skills Gap Index) and GCI (The Global Competitiveness Index).

description: The article considers the issues of IoT systems and networks privacy. The complex researches on general system theory state of the art has been surveyed, as well as cybersecurity aspects of IoT technologies and models analyzed over the past decades with respect to the Industry 4.0 concept and industrial IoT architecture. A comprehensive decomposition formalism proposed on the base of M. Mesarowic system theory for presenting the complex cybersecurity object of study as a set of its parts. An original context-defined model of open systems interaction S-CDM has been constructed for cybersecurity issues study with the use of J. Neumann classification and A. Uemov system triad. The S-CDM model is shaped in 3-layer hierarchical graph. The first S-CDM layer displays the cybersecurity problem as a set of relations between the key players of information market  resources, clients and agents. The second S-CDM layer adds the network technologies impact on the relations between the key market-players. The third S-CDM layer includes a “degree of trust” factor into the key market-player relationships. The introduced context-defined model enables to reduce the overall problem complexity of the IoT cybersecurity study to a number of less complex and easy-handled partial tasks. As an example, a particular local version of the S-CDM model is considered in the form of six independent tasks for AI-aided methods of cybersecurity provision. The results of the work intend to contribute general system researches in the sphere of network system modelling and IoT privacy.

description: Abstract: Although young adults are generally healthy, they often engage in risky behaviours and establish lifestyle patterns that have costly immediate and long-term health impacts (e.g. poor nutrition, inactivity, substance misuse). Many young people attend colleges and universities making campuses an ideal setting for interventions. Setting based health promotion approaches have been used to improve health of populations and communities, including campus communities, however, creating change that is meaningful to students and also organizational leaders (non-students) has been difficult. In 2006 at a rapidly growing campus in Canada, a program of research was started to increase knowledge about healthy campus development. The VOICE Study uses community based participatory action research methods in combination with setting based health promotion strategies. Students and organizational leaders (non-students) work as co-researchers and project partners to identify priority health issues and create health promoting change (individual and community levels). While the idea of campus community members working together on health related issues is appealing to many, diverse views exist about the responsibility of post-secondary institutions to promote health; some prefer an individual responsibility or consumer model. An ecosystem model of health and community informs this study. Photographic, quantitative and qualitative research methods have been used according to questions of interest. Action groups have been formed around diverse topics, for example, drinking water, “real” food, natural environment, physical activity, transportation and student space. Results indicate that the process of creating change through use of a methodological framework combining action research, setting based health promotion and youth/adult partnerships, is highly effective. Diverse students (youth) and organizational leaders (adults must be full partners throughout the process. Patience, persistence and a sense of humor are basic requirements. The results appear to be transferable to other settings when the egalitarian values embedded in the methodological framework are explicit, and the community designs the specifics (e.g. issues, actions) to fit their context. Study processes, outcomes, challenges and successes are discussed, followed by a case study on campus food to illustrate more specifically the use of the methodological framework and results.

description: Distillers Dried Grains with Solubles (DDGS), a co-product of the bioethanol industry, is emerging as a highly valuable feed ingredient for livestock in India. With increasing bioethanol production, DDGS provides a sustainable and cost-effective alternative to traditional feed components, particularly in dairy, poultry and aquaculture diets. This article explores the chemical composition and physical attributes of DDGS, detailing its advantages in improving growth rates, feed conversion ratios, and overall health parameters across animal sectors. Key challenges, including quality variability, handling, and nutritional balancing, were also addressed. Optimized use of DDGS through enzymatic treatments and proper dietary formulation can offer an economically and nutritionally efficient solution, enhancing India’s agricultural sustainability and livestock productivity.

Application of an inverse method to interpret 231Pa/230Th observations from marine sediments
Creators: name: François, Roger
Publisher: name: American Geophysical Union
Year: 2017

description: Records of 231Pa/230Th from Atlantic sediments have been interpreted to reflect changes in ocean circulation during the geologic past. Such interpretations should be tested with due regard to the limited spatial coverage of 231Pa/230Th data and the uncertainties in our current understanding of the behavior of both nuclides in the ocean. Here an inverse method is used to evaluate the information contained in 231Pa/230Th compilations for the Holocene, Last Glacial Maximum (LGM), and Heinrich Event 1 (H1). An estimate of the abyssal circulation in the modern Atlantic Ocean is obtained by combining hydrographic observations and dynamical constraints. Then sediment 231Pa/230Th data for each time interval are combined with an advection-scavenging model in order to determine their (in)consistency with the modern circulation estimate. We find that the majority of sediment 231Pa/>230Th data for the Holocene, LGM, or H1 can be brought into consistency with the modern circulation if plausible assumptions are made about the large-scale distribution of 231Pa and about model uncertainties. Moreover, the adjustments in the data needed to reach compatibility with a hypothetical state of no flow (no advection) are positively biased for each time interval, suggesting that the 231Pa/230Th data (including that for H1) are more consistent with a persistence of some circulation than with no circulation. Our study does not imply that earlier claims of a circulation change during the LGM or H1 are inaccurate, but that these claims cannot be given a rigorous basis given the current uncertainties involved in the analysis of the 231Pa/230Th data.

description: The global rise in crime rates is a result of the ineffectiveness of the traditional punishment system and the need to develop new approaches to applying relevant punitive measures to criminals, taking into account their level of danger to society. This paper presents a classification Decision Trees model to identify significant factors influencing the objective level of danger a convicted person poses to society. Applied research was conducted based on real data (individual characteristics and criminal history records) of 2,052 convicts serving sentences in correctional facilities in Ukraine. It was found that the most significant predictors for determining the level of danger to society were the number of previous incarcerations and the number of suspended sentences. Assessing the level of societal danger posed by convicts is one of the key aspects of upholding the principles of fair justice. The obtained results can serve as informational support for judicial decisions, ensuring a balance between societal protection and successful offender reintegration.

RUSSIAN AMBITIONS AND HYBRID MODES OF WARFARE

Publisher: name: The Estonian Journal of Military Studies
Year: 2024

description: The security policy of the Russian Federation has long involved elements of threat to neighbouring countries and forcing the hand of its political partners. In the last decade, Russia has used hybrid modes of warfare to instigate conflicts and instability in its neighbouring countries, while remaining below a certain threshold of violence, allowing it to dodge retaliatory consequences. The authors of the article indicate that the objective of the use of hybrid modes of warfare in Ukraine consists in blurring motives and actors in order to obfuscate a decisive and efficient response. This article argues further that these tactics, if used against a member of the Atlantic Alliance, would effectively allow such an attack to remain below the Article 5 applicability threshold, thereby making it difficult for alliance members to reach consensus on the characterisation of the attack. Even though the member states of NATO and the EU have not been direct targets of Russian actions, former republics of the Soviet Union can be considered to be in the danger zone, based on Russian political statements and its hybrid activities in these countries.

description: The term “hybrid war” is not particularly novel – it was first used by Frank Hoffman in 2007 in his presentation “Conflict in the 21st Century: The Rise of Hybrid Wars” at the Potomac Institute for Policy Studies. Hybrid war is often considered as a precursor to large-scale military operations and irregular war. However, that is not an entirely accurate description because hybrid war entails the use of military resources in combination with other means of influence, such as clandestine operations, political activities, cyber operations, information operations, economic activities, and diplomacy. Russia has been using hybrid warfare for a long time, but in 2013 it was finally introduced as an official doctrine by Valery Gerasimov, Chief of the General Staff of the Russian Armed Forces. The focal point of the doctrine was the concept of influence, which is based on the idea that the main battlefield resides in the minds of the people, and consequently, in the future, information and psychological operations will take precedence in waging war and will be aimed at undermining the morale of the adversary’s military and its civilian population. Russia usually engages in this kind of behaviour in order to win time before the international community comes to the realisation that it is Russian aggression they are dealing with. The Russian minorities in its near abroad play an important role in hybrid warfare because Russia can always appeal to be “acting in defence” of their interests. In the Georgian case, those minorities were in Abkhazia and South Ossetia. After President Saakashvili assumed power in Georgia and began steering the country towards joining NATO, Russia felt the urge to interfere in order to keep Georgia within its sphere of influence, especially considering its importance as a transit route for Azerbaijan’s oil and gas. Therefore, the outbreak of war in August 2008 was not decided by the presidents of Russia or Georgia, the decision was made much earlier. During NATO’s 2008 Bucharest summit, Georgia was given hope with regard to becoming a full member of NATO, and that served as the main catalyst behind the hybrid war launched against it by Russia. Thus, the so-called August War of 2008 constitutes just one small battle in the ongoing longterm conflict between the two countries, while secessionist Abkhazia and South Ossetia are just pawns used by Russia to influence Georgia.

description: In this research, we analyse how Long Short-Term Memory (LSTM) models can predict photovoltaic (PV) power output, in Abuja, Nigeria by selecting specific climate features and model configurations. The rising energy needs due to population growth and urbanisation emphasise the importance of sustainable energy sources. This study aims to improve the accuracy of PV power forecasts for integrating power into the current electrical grid and enhancing energy management strategies. By analysing data from the ERA5 dataset that includes various climatic features, we rigorously trained and assessed the LSTM models. Our results indicate that specific window sizes and combinations of features notably enhance forecasting accuracy with a window size of 6 and a mix of meteorological and solar radiation features showing the performance metrics (MAE, RMSE, R²). The study also underscores the significance of autocorrelation and cross-correlation analyses in optimizing model setups. Our findings suggest that LSTM models can accurately predict PV power output offering insights for maximizing energy usage in urban areas with similar climates. This research contributes to efforts aimed at reducing reliance on fossil fuels and promoting sustainable energy solutions. Future endeavours will explore integrating real-time data and incorporating additional climatic features to further refine forecasting models.

description: In this paper, we present the implementation of the Quantum Approximate Optimization Algorithm (QAOA) for the Max-Cut problem using the JavaScript programming language. The Max-Cut issue, which involves partitioning the vertices of a graph into two subsets such that the number of edges between the subsets is maximized, is a well-known NP-hard difficulty with numerous practical applications, including network design and resource allocation. The implementation of QAOA in JavaScript is a significant step towards integrating quantum computing with modern web technologies, thus broadening access to quantum algorithms among software developers. Quantum algorithm implementation leverages the principles of quantum mechanics, such as superposition and entanglement, to approximate solutions to combinatorial optimization issues. The quantum.js framework, developed in the context of this research, facilitates the construction and manipulation of quantum circuits in a web environment. The framework includes functions for building quantum circuits, optimizing the parameters of the QAOA algorithm, and visualizing the resulting quantum states. By enabling the execution of quantum algorithms in a web-based setting, this work demonstrates the potential for utilizing quantum computing capabilities within popular web development environments. The results highlight the efficiency of QAOA in providing approximate solutions to the Max-Cut, offering a promising alternative to classical optimization methods. Future work will focus on enhancing the framework by adding cloud-based quantum computing capabilities, expanding the documentation, incorporating additional quantum-hybrid algorithms, and improving the user interface of the associated web application.

description: This article reviews a large body of research on optimizing the ElGamal cryptosystem for increased hardware and software efficiency. Areas of effort identified in the research include, hardware acceleration, hybrid systems combining ElGamal with symmetric cryptosystems, software advancements through adjustments to mathematical difficulties, and hybrids with other asymmetric cryptosystems. There is a clear demonstration that hybrid systems that combine ElGamal with symmetric encryption and software improvement through adjustments to the mathematical difficulties are highly impactful with about 95% score based on the amount of research done in the area. This indicates the significance of these domains for the further evolution of the ElGamal cryptosystem. Hybrid systems which seek to combine Elgamal with symmetric cryptosystems, such as AES, has become a very crucial area that needs a high level of concentration. This ensures both high level of security and greater enhancement to the time complexity. Through these changes, performances were improved and computational overhead were decreased by optimizing the underlying mathematical operations and combining Elgamal with other symmetric algorithms. The article proposes ChaCha20-Poly1305 as a potential for further improvement in hybrid encryption.

description: Der kurze Krieg um Südossetien und Abchasien zwischen Georgien und Rußland Anfang August 2008 hat erneut die Kriegsträchtigkeit und die internationale Brisanz lokaler „eingefrorener Konflikte“ demonstriert. Er hat die politische Lage im Kaukasus drastisch verändert, erneut ethnische Vertreibungen ausgelöst und zeitweilig die Beziehungen zwischen Rußland und dem Westen erheblich getrübt, so daß von einem neuen „kalten Krieg“ geredet wurde. Nach der russischen Annexion der Krim und der Einrichtung eines Separatistenregimes im Donbass im Frühjahr 2014 hat sich diese Sorge nochmals verschärft. Nachdem Rußland im Verlaufe des Krieges in Georgien die territoriale Einheit der beiden De-facto-Staaten in den Grenzen, die von der frühen Sowjetmacht in den 1920er Jahren festgelegt worden waren, wieder hergestellt und die Unabhängigkeit der beiden Staaten anerkannt hatte, entstand eine neue Frontlinie zwischen dem Westen und Rußland. Allerdings wurden dann doch die Pläne, Georgien in die NATO aufzunehmen, vertagt. Sonst wären Truppen des Westens und Rußlands auch in dieser Region in unmittelbarer Nachbarschaft stationiert gewesen. Die neue Grenzlinie ist besonders prekär, da der Westen auf der territorialen Integrität Georgiens beharrt, die Unabhängigkeit Südossetiens und Abchasiens nicht anerkennt und somit von einer rechtswidrigen Präsenz rußländischer Truppen auf NATO-Gebiet hätte sprechen müssen, hätte er Georgien in die NATO aufgenommen. Rußland hatte schon lange vor der absehbaren Anerkennung der Unabhängigkeit Kosovos durch die meisten westlichen Staaten, die sogleich nach der förmlichen Unabhängigkeitserklärung des kosovarischen Parlaments am 17. Februar 2008 erfolgte, gewarnt, daß es seinerseits mit einer Anerkennung Südossetiens und Abchasiens reagieren könne. Während die westliche Anerkennung der Separation Kosovos völkerrechtswidrig sei, sei hingegen eine Anerkennung Südossetiens und Abchasiens mit dem Völkerrecht vereinbar. Dennoch zögerte Rußland in den folgenden Monaten, diesen Schritt zu gehen. Erst nach dem Angriff Georgiens auf Südossetien am 7. August ging Rußland zum militärischen Gegenangriff über, erkannte die Unabhängigkeit Südossetiens und Abchasiens an und ließ sich von beiden zu einer stärkeren Truppenpräsenz in beiden Gebieten einladen, nachdem die EU einen Waffenstillstand zwischen Rußland und Georgien vermittelt hatte. Nunmehr stellten sich folgende Fragen. Werden der Westen und Rußland längerfristig bereit sein, wechselseitig die Unabhängigkeit „ihrer“ De-facto-Staaten Kosovo, Südossetien und Abchasien anzuerkennen? Werden beide Seiten willens sein zu verhindern, daß diese drei Anerkennungsakte zu Präzedenzfällen für die anderen De-facto-Staaten in Europa und in der Welt werden? Sind beide Seiten fähig, Kompromisse für diese anderen Fälle zu entwickeln? Und welche Folgen hat die neue Lage für das nunmehr endgültig geopolitisch isolierte Armenien?
