Abstract:

Brachial plexopathy is a type of peripheral neuropathy. Injuries to the brachial plexus can be classified according to their severity, ranging from neuropraxia, the mildest form, to axonotmesis and neurotmesis, the most severe forms. The causes of brachial plexopathy include traumatic and non-traumatic injuries. Because the brachial plexus can sustain various types of injuries, different imaging modalities are required. Recent advances in diagnostic imaging have enabled better investigation of brachial plexopathy. This article reviews the major and most widely used imaging methods used for investigating brachial plexopathy along with newer modalities. The indications, advantages, and disadvantages of each modality are examined. The major factor in realizing the full potential of any imaging method is the knowledge of the requesting physician about the capabilities and limitations of each method. Magnetic resonance imaging (MRI) is the standard imaging modality for evaluating non-traumatic injury to the brachial plexus; however, there are several limitations to its use and, therefore, other modalities should be pursued. MR myelography should be used for traumatic meningoceles and root avulsions. MR neurography is a relatively new technique with massive potential. It is a tissue-specific modality with the ability to elicit morphological as well as pathological features of nerves. CT myelography is the gold standard for evaluating traumatic injury of the brachial plexus. Other potential uses are with tumors of the brachial plexus as well as obstetric brachial plexus palsies. Finally, sonography is addressed. With its ability to detect almost all plexopathies and the fact that it does not employ radiation and can be done in virtually every patient, it should be the baseline or, at least, the screening method for plexopathies.

Abstract:

Russia is currently at a fork in its economic trajectory. In this regard, issues of territorial development are particularly relevant in the country’s transition to investment-type economic growth. The investment process is the main subject of technical analysis, quality control and regulation at the state and regional levels of management. The purpose of the article is to identify the relationship between such regional characteristics as the state of the investment climate, investment attractiveness, socio-economic situation, index of physical volume of investment in fixed assets based on the analysis of state policy in the field of territorial development. The research used methods of comparative, statistical and system analysis, deduction and induction, generalization, and theoretical modeling. As a result of the study, it was revealed that the state actively supports regions – growth points where special economic zones and territories of advanced development are created, but at the same time, there is an active state support for regions with a low level of socio-economic development. A study of the basic characteristics of the investment development of the Russian regions showed that those regions in which there is a favorable investment climate tend to have high investment attractiveness. However, there is no direct correlation between the level of socio-economic development of the region and the state of its investment climate. Therefore, in order to increase the investment attractiveness of Russian regions, it is necessary to create such macroeconomic goals for Sevastopol that will help to intensify the results of investment processes, remove various bureaucratic barriers for investors in the region, develop tools for the coordinated use of territories, and actively develop interregional cooperation.

Abstract:

In the interaction of cosmic rays (CRs) with Earth’s atmosphere, neutrons are formed in a wide range of energies: from thermal (E≈0.025 eV) to ultrarelativistic (E>1 GeV). To detect and study CRs, Polar Geophysical Institute (PGI) uses a complex monitoring system containing detectors of various configurations. The standard neutron monitor (NM) 18-NM-64 is sensitive to neutrons with energies E>50 MeV. The lead-free section of the neutron monitor (BSRM) detects neutrons with energies E≈(0.1÷1) MeV. Also, for sharing with standard detectors, the Apatity NM station has developed and installed a neutron spectrometer with three energy channels and a particle reception angle of 15 degrees. The configuration of the device makes it possible to study the degree of anisotropy of the particle flux from different directions. We have obtained characteristics of the detector (response function and particle reception angle), as well as geometric dimensions through numerical simulation using the GEANT4 toolkit [Agostinelli et al., 2003]. During operation of the device, we collected database of observations and received preliminary results.

Abstract:

To date, taking into account the strategies for the development of control systems and the active introduction of distributed generation sources into various spheres of the world economy, including those based on renewable sources of electrical energy, hybrid systems of artificial outdoor lighting controlled by intelligent control systems are being developed. The paper proposes an approach to the construction of an external lighting control system on city highways and public places. Regulation of external lighting is carried out by adjusting the luminous flux of lamps, and the sources of luminous flux are the lamps with which they are equipped. But not all types of lamps are suitable for adjusting the smooth change of light flux. If there is a communication channel between the network of lamps equipped with EIDs and the dispatching service, it is possible to transmit information about the state of operation of EIDs and the performance of lamps in order to detect deviations in the operation of EIDs and lamps that need to be replaced. In accordance with the given schedule for changing the level of external lighting, the KD software sends a command to change the level of light flux on specific lamps. The control unit transmits incoming information (a command) to the control unit, which, together with the lamp control channel connected to it, forms a local lighting control network. The decentralized outdoor lighting control system provides for the absence of a control room, server, server access devices, as well as the Internet as a means of communication, executive equipment of the substation and replacement of the PUS with the APUS, as well as the presence of service personnel who will service the equipment of the APUS substation, KOP and SC, as a result of the lack of feedback from the APUS to the OP, i.e. the maintenance of the PS is carried out directly by maintenance and programming specialists Thus, a scheme for decentralized management of outdoor lighting on city highways and public places was proposed.

Abstract:

Currently, Korea is achieving cultural, economic, and social growth as a member of the international community along with its social growth. In the 2000s, local communities and local governments made multidimensional efforts with historical and cultural interests. And as part of that, historical museums were built or expanded to increase the quantity in anticipation of citizens' satisfaction and attracting visitors. However, the qualitative effect of the exhibition space is not achieved. Therefore, in this study, the analysis according to the complex system theory on the interrelationship between exhibition planning, space, and spectators was carried out based on the case of domestic historical museums, and future exhibition space planning or movement lines according to the mutual relationship between the exhibition space and the spectators were conducted. The purpose of this study is to conduct research on specific visualization and data derivation regarding spatial density and spatial perception information.

Abstract:

Complex systems theory is concerned with identifying and characterizing common design elements that are observed across diverse natural, technological and social complex systems. Systems biology, a more holistic approach to study molecules and cells in biology, has advanced rapidly in the past two decades. However, not much appreciation has been granted to the realization that the human cell is an exemplary complex system. Here, I outline general design principles identified in many complex systems, and then describe the human cell as a prototypical complex system. Considering concepts of complex systems theory in systems biology can illuminate our overall understanding of normal cell physiology and the alterations that lead to human disease.

Abstract:

Another chaotic nonlinear Lü model with complex factors is covered here. We can build this riotous complex system when we add a complex nonlinear term to the third condition of the complex Lü system and think of it as if every one of the factors is mind boggling or complex. This system in real adaptation is a 6-dimensional continuous autonomous chaotic system. Different types of chaotic complex Lü system are developed. Also, another sort of synchronization is presented by us which is simple for anybody to ponder for the chaotic complex nonlinear system. This sort might be called a complex antilag synchronization (CALS). There are irregular properties for CALS and they do not exist in the literature; for example, (i) the CALS contains or fused two sorts of synchronizations (antilag synchronization ALS and lag synchronization LS); (ii) in CALS the attractors of the main and slave systems are moving opposite or similar to each other with time lag; (iii) the state variable of the main system synchronizes with a different state variable of the slave system. A scheme is intended to accomplish CALS of chaotic complex systems in light of Lyapunov function. The acquired outcomes and effectiveness can be represented by a simulation case for our new model.

Abstract:

Some of agriculture-food sector information systems are characterised by a high complexity and a large size. There are often many alternative solutions or technologies (implementation methods) and more then one possible way or approach to an information system design. Individual alternatives could considerably differ by their properties, e.g. costs of design of initial functionality, development and operational costs, run-time costs and technical parameters of the resulting information system (e.g. the access time). Unfortunately, existing metrics for quantification of this task usually do not deliver precise results but a rough estimate depending on many variable conditions. The paper will outline typical implementation methods and show approaches to assessment and comparison of certain types of properties of information systems for a computer support for management of large data systems, which use relational database. Authors presented part of these results also at the Agrarian Perspectives conference 2004 in the Applied Informatics session (Vrana I., Vrána J. 2004).

Abstract:

Considering a synergistic approach to the development of complex technologies for the production of the agro-industrial complex is considered. An analysis of the prospects for the unification of manufacturing and processing industries is given. The features of the structure of simple, small, large and complex technological systems are described. The influence of the stages of digitalization in the new synergetic picture of the agricultural complex is revealed. To effectively use the existing capacities of agrarian and food technologies and predict their further development, a qualitative change in the state of the entire complex system of the complex is considered, to identify control parameters and the least stable modes. The development of technological processes is considered taking into account the synergistic effects of interaction. Bifurcation transitions on the way of obtaining products and system-forming factors of the organization of complex technological production systems are described. The influence of internal and external relations on the structure of small and large systems of processing and food industries is analyzed.

Abstract:

Introducción Un sistema complejo, debe abordarse desde la interdisciplina, en la que confluyen múltiples procesos en un sistema de red organizada (García, 1986). En el pensamiento complejo es en donde se hace posible el surgir de nuevos conocimientos, en los niveles de lo cuantificable, a través del método científico, para descubrir distintas formas de representar una realidad. A partir de esto surge la interdisciplina desde la acción social, política, económica, entre otras, las mismas que pueden generar cambios de una realidad no deseable (López Quintás, 2001). Objetivos Brindar una comprensión acerca de los sistemas complejos y cómo la interdisciplina juega un papel fundamental en la misma. Método Se realiza una revisión bibliográfica, empleando palabras clave como interdisciplina, pensamiento complejo, sistema complejo, con operadores boleanos and y or; los criterios de inclusión considerados son, artículos de revisión, y libros clásicos y contemporáneos, en un total de 80 revisiones. Principales resultados Se realiza una revisión, de cómo el concepto “sistema complejo” ha ido evolucionando en el tiempo, y la importancia de que sea abordado desde la interdisciplina, así: Herbert and Simon (1962), señalan que un sistema complejo está formado por un gran número de partes que interactúan entre sí, pero a la vez actúan con autonomía. Bertalanffy (1968), lo interpreta como un todo, que conduce a una mejor comprensión de las ciencias biológicas, las del comportamiento y las sociales. Morin (1993), lo presenta como un tejido de componentes heterogéneos inseparablemente asociados. Nicholis and Prigogine (1994), habla de sistemas que aprenden y se adaptan. Murray (1995) articula diferentes ciencias en una única estructura conexa. De Sousa Santos (2009), propende un conocimiento total; pero que siendo total, es también local. Holland (2012), indica que en un sistema complejo no hay un elemento superior a los demás, hay una mutua dependencia entre todos. Para Maldonado (2014), la complejidad consiste en asociaciones, o complementariedades, entre escalas y densidades temporales diferentes. Repko (2016), se basa en conocimientos disciplinarios para un enfoque en la integración interdisciplinaria. Conclusiones La interdisciplina permite buscar canales y redes de conexión para una mayor comprensión de un problema existente. Se concluye que la visión disciplinaria debe cambiar a un enfoque más amplio que debe adecuarse a la comprensión de la realidad en el contexto en el que se encuentra. Los procesos metodológicos en investigación se encuentran en constante mutación; dando paso a nuevas concepciones que lleven a un entendimiento de una realidad compleja.

Abstract:

The correct determination of the energy efficiency (EE) of a complex system is a problematic task that requires the use of specialized methods and approaches. Most often, EE is considered as an indicator of the quality-of-service provision, which most fully corresponds to the technical and economic essence of this indicator. The structural and functional organization of the system of such indicators is carried out either on a bottom-up approach or a top-down approach, gradually deploying macroeconomic indicators defined at the system levels. This paper considers the tensor form of organization of the system of such indicators, which allows combining within a single model not only their organizational levels (economy as a whole, economic sectors, enterprises, technologies and equipment), but also the types of activities that reflect these indicators (energy, financial, economic, institutional, environmental, social, etc.), and the factors of changes in energy use (structural, technological, resource, managerial, regulatory, etc.). The paper presents the mapping of this model on the plane of structural and functional factors in the form of classification tables (matrices) of these factors (system elements). The paper describes the procedure for optimizing indicators, which can be carried out for each of these factors separately, their aggregate at each level and for the system as a whole, taking into account the need to implement iterative procedures for coordinating the global (system-wide) goal and local objective functions. Given the use of optimization variables measured in energy and monetary units, this problem is formalized within the framework of the set-theoretic approach. For the purpose of comparing the results, the paper examines the relevant provisions of the International Energy Agency methodology, which uses the direct method of three-factor Laspeyres decomposition analysis, and the Sectoral Methodology for Calculating Harmful Emissions of the Ministry for Communities and Territories Development of Ukraine. Keywords: Energy efficiency, energy efficiency indicators, system analysis, tensor approach.

Abstract:

This article explores the role of the United Nations (UN) within the complex interdependence system of regional security. In an era marked by global interconnectedness and interdependence, regional security challenges necessitate a multilateral approach. The UN, as a global organization, assumes a critical role in addressing these challenges due to its mandate, resources, and convening power. The article begins by elucidating the concept of complex interdependence, emphasizing the intricate web of relationships and interconnections among states and non-state actors in the realm of regional security. It underscores the significance of comprehending the multifaceted nature of contemporary security concerns and the imperative of collaboration and cooperation among nations. Subsequently, the article investigates the UN's role in the complex interdependence system. It examines the UN's mandate, which encompasses the promotion of peace, security, and stability at both regional and global levels. The institutional framework of the UN, including the Security Council, General Assembly, and specialized agencies, provides platforms for dialogue, negotiation, and coordination among member states. Moreover, the article explores the UN's resources and capabilities in addressing regional security issues. It highlights the UN's peacekeeping operations, conflict prevention and mediation efforts, and humanitarian assistance initiatives as crucial tools for fostering regional security. Additionally, it underscores the UN's normative framework, encompassing international law and human rights, as essential components in the pursuit of regional security. Furthermore, the article analyzes the UN's convening power and its ability to bring together diverse actors to collectively address regional security challenges. It discusses the UN's role as a platform for dialogue, diplomacy, and consensus-building, facilitating regional cooperation and fostering trust among states. Lastly, the article acknowledges the limitations and challenges faced by the UN within the complex interdependence system of regional security. It recognizes the need for ongoing efforts to enhance the UN's effectiveness, responsiveness, and adaptability to evolving security dynamics. In conclusion, this article underscores the indispensable role of the UN within the complex interdependence system of regional security. By leveraging its mandate, resources, and convening power, the UN significantly contributes to the cultivation of peaceful and stable regional environments in an era characterized by interconnectedness and interdependence.

Abstract:

National infrastructure systems spanning energy, transport, digital, waste, and water are well recognised as complex and interdependent. While some policy makers have been keen to adopt the narrative of complexity, the application of complexity-based methods in public policy decision-making has been restricted by the lack of innovation in associated methodologies and tools. In this paper we firstly evaluate the application of complex adaptive systems theory to infrastructure systems, comparing and contrasting this approach with traditional systems theory. We secondly identify five key theoretical properties of complex adaptive systems including adaptive agents, diverse agents, dynamics, irreversibility, and emergence, which are exhibited across three hierarchical levels ranging from agents, to networks, to systems. With these properties in mind, we then present a case study on the development of a system-of-systems modelling approach based on complex adaptive systems theory capable of modelling an emergent national infrastructure system, driven by agent-level decisions with explicitly modelled interdependencies between energy, transport, digital, waste, and water. Indeed, the novel contribution of the paper is the articulation of the case study describing a decade of research which applies complex adaptive systems properties to the development of a national infrastructure system-of-systems model. This approach has been used by the UK National Infrastructure Commission to produce a National Infrastructure Assessment which is capable of coordinating infrastructure policy across a historically fragmented governance landscape spanning eight government departments. The application will continue to be pertinent moving forward due to the continuing complexity of interdependent infrastructure systems, particularly the challenges of increased electrification and the proliferation of the Internet of Things.
