Продемонстрована проблема параметричної невизначеності газових ректифікаційних колон,  зміна параметрів в термінах моделі в вигляді інерційної ланки з запізненням проходить синхронно й в робочому режимі така зміна може бути троєкратною. У результаті сформовані вимоги до розробки сучасних систем керування газофракційними установками, дотримання яких дозволяє підвищити ефективність та надійність їх роботи та рівень дотримання регламентних норм.
APPLICATION OF AGILE PRINCIPLES IN THE ORGANIZATION OF SERVICE UNITS OF HIGHER EDUCATION INSTITUTIONS. PART 1
Authors: Olshevska Olga , Zinchenko Iryna , Sakaliuk Oleksii , Kozub Oksana , Kolesnyk Valery
Published: September 2023

The publication deals with the application of Agile principles in organizing the work of service units of higher education. The first part of the publication deals with theoretical aspects of the methodology. Agile does not exist by itself, but is structured and carries out all processes with the so-called Agile Manifesto, consisting of 12 principles. It is found out, to what extent it will be correct to transfer the principles of Agile-manifesto to the system of higher educational institutions. The basic principles, which can guide the administration of the service units of the HEIs, are defined. Agile's definition is articulated in the Agile manifesto of software development, which emphasizes that people and communication take precedence over processes and tools. A functioning product is more important than extensive documentation, and collaborating with customers is more important than negotiating contractual terms. Additionally, being willing to adapt and change is more important than sticking to the original plan. Numerous project management approaches exist to apply the Agile philosophy, with Scrum, Extreme Programming, and Kanban being among the most prevalent. Among project managers, Scrum project management is widely used as one of the most popular Agile methodologies. The second part of the publication identifies the differences and similarities between Agile and Scrum. The third part of the publication examines the application of the methodology in practice. It is important to focus on constantly changing external and internal environment and take into account the feedback from customers and users. This encourages developers and engineers to experiment and look for new solutions without being constrained by rigid frameworks and standards.
LICENSE PLATE RECOGNITION SYSTEM BASED ON MASK R-CNN
Authors: Onishchenko D. , Liubchenko N. , Podorozhniak A.
Published: September 2023

Automatic license plate recognition (ALPR) systems can be found in many different applications. If a person has a driving license, the person probably had already seen smart road camera after a speed limit sign or on a crossroad. Every year number of cars on roads growth very fast. It is also obvious that such systems can be used out-of-road situations. For instance, this type of systems can be used for automatic access control on private property or smart parking, or even log system that are being used literally everywhere. Because of popularity of ALPR systems, there are two main goals, which are being pursued by researches: speed and accuracy of recognition. Speed of the detection is important for real-time systems. Accuracy is important for every system. The more accurate a system is, the more reliable it is. For example, car accident detection systems should be as accurate as possible in order to be used, because no one wants to get billed with the wrongdoing, that wasn’t committed by them.
The purpose of the study is to develop high precision automatic license plate detection system with number extraction possibilities. In order to achieve the goal many different modern solutions and technologies were studied and solution is presented. The main technology of the project is artificial intelligence system and, more specifically, convolutional neural network. As the main algorithm Mask R-CNN is used for license plate detection. To present reasonable research, the system was tested on different hardware (CPU, GPU, Raspberry PI 4) and on different datasets.
NUMERICAL SOLUTION OF COUPLED HEAT TRANSFER WITH PHASE CHANGE AND THERMITE REACTION
Authors: Pena Fabrício J.C. , de Lemos Marcelo J.S.
Published: September 2023

The thermite reaction is a self-sustained exothermic reaction commonly employed in welding processes
of railway tracks, material synthesis, pyrotechnics, etc. More recently, this reaction has been assessed
to plug depleted oil wells. The investigated geometry is modeled as a two-dimensional axisymmetric
domain with a thermite mixture compressed between a polymethylmethacrylate (PMMA) lid and
a stainless steel disk. First-order kinetic is assumed for the chemical kinetics model. The governing
equations are discretized with the finite-volume approach. Experimental validation is performed by
comparing numerical combustion velocities and peak temperatures with the experimental data in the
literature. The results demonstrate a remarkable thermal gradient through the longitudinal direction,
displaying higher thermal losses next to the thermite-steel interface. These heat losses also affect the
melting of species, as a small portion of alumina remains entirely solid during the reaction.

Authors: Wang Wei , Sun Min , Yu Jinyan , Ma Xumin , Han Chunchao
Published: September 2023

Coprinus comatus is rich in a variety of nutrients, which has been reported to display a good hypoglycemic effect. However, there is no consensus on the hypoglycemic mechanism of this mushroom. Intestinal microbiota, a complex and intrinsic system, is closely related to metabolism. In this review, we discussed the potential relationship between certain components of C. comatus and intestinal microbiota to illustrate the possible hypoglycemic mechanism of C. comatus through intestinal microbiota. It will provide a new perspective for the study of hypoglycemic mechanism of C. comatus and promote the development and utilization of this mushroom.

Authors: Chaudhuri Alok Ghosh , Samanta Saptadip , Dey Monalisha , Raviraja N. S. , Dey Souvik
Published: September 2023

Alpha-fetoprotein (AFP) belongs to the albuminoid protein family and is considered as the fetal analog of serum albumin. This plasma protein is initially synthesized in the fetal liver and yolk sac and shows a maximum peak near the end of the first trimester. Later, concentrations begin to decline prenatally and drop precipitously after birth. This protein has three key ligand-binding pockets for interactions with various biomolecules. It contains multiple phosphorylation and acetylation sites for the regulation of physiological and pathophysiological states. High serum AFP titer is an established biomarker for yolk sac, embryonal and hepatocellular carcinoma. The present review critically analyzes the chemical nature, receptors, clinical implications, and therapeutic aspects of AFP, underpinning the development of different types of cancer.
PHYSICS-INFORMED NEURAL NETWORKS BASED ON SEQUENTIAL TRAINING FOR CO2 UTILIZATION AND STORAGE IN SUBSURFACE RESERVOIR
Authors: Pour Kiarash Mansour , Voskov Denis
Published: September 2023

CO2 utilization and storage (CCUS) simulation in subsurface reservoirs with complex heterogeneous structures necessitates a model that can capture multiphase compositional flow and transport. The governing equations are highly nonlinear due to the complex thermodynamic behavior, which involves the appearance and disappearance of multiple phases. Accurate simulation of these processes necessitates the use of stable numerical methods. While machine learning (ML) approaches have been used to solve a variety of nonlinear computational problems, a new approach based on physics-informed neural networks (PINNs) has been proposed for solving partial differential equations (PDEs). Unlike typical ML algorithms that require a large dataset for training, PINNs can train the network with unlabeled data. The applicability of this method has been explored for multiphase flow and transport in porous media. However, for nonlinear hyperbolic transport equations, the solution degrades significantly. This work proposes sequential training PINNs to simulate two-phase transport in porous media. The main concept is to retrain the neural network to solve the PDE over successive time segments rather than train for the entire time domain simultaneously. We observe that sequential training can capture the solution more accurately concerning the standard training for conventional two-phase problems. Furthermore, we extend the sequential training approach for compositional problems in which nonlinearity is more significant due to the complex phase transition. Our approach was tested on miscible and immiscible test cases and showed higher accuracy than the standard training method.

Resistance to radiation remains a significant clinical challenge in non-small cell lung carcinoma (NSCLC). It is therefore important to identify the underlying molecular and cellular features that drive acquired resistance. We generated genetically matched NSCLC cell lines to investigate characteristics of acquired resistance. Murine Lewis lung carcinoma (LLC) and human A549 cells acquired an approximate 1.5–2.5-fold increase in radiation resistance as compared to their parental match, which each had unique intrinsic radio-sensitivities. The radiation resistance (RR) was reflected in higher levels of DNA damage and repair marker γH2AX and reduced apoptosis induction after radiation. Morphologically, we found that radiation resistance A549 (A549-RR) cells exhibited a greater nucleus-to-cytosol (N/C) ratio as compared to its parental counterpart. Since the N/C ratio is linked to the differentiation state, we next investigated the epithelial-to-mesenchymal transition (EMT) phenotype and cellular plasticity. We found that A549 cells had a greater radiation-induced plasticity, as measured by E-cadherin, vimentin and double-positive (DP) modulation, as compared to LLC. Additionally, migration was suppressed in A549-RR cells, as compared to A549 cells. Subsequently, we confirmed in vivo that the LLC-RR and A549-RR cells are also more resistance to radiation than their isogenic-matched counterpart. Moreover, we found that the acquired radiation resistance also induced resistance to cisplatin, but not carboplatin or oxaliplatin. This cross-resistance was attributed to induced elevation of thiol levels. Gamma-glutamylcysteine synthetase inhibitor buthionine sulfoximine (BSO) sensitized the resistant cells to cisplatin by decreasing the amount of thiols to levels prior to obtaining acquired radiation resistance. By generating radiation-resistance genetically matched NSCLC we were able to identify and overcome cisplatin cross-resistance. This is an important finding arguing for combinatorial treatment regimens including glutathione pathway disruptors in patients with the potential of improving clinical outcomes in the future.
"Feminine, Not Feminist": Trad Truth-making on Social Media
Authors: Deem Alexandra
Published: September 2023

This article investigates the truth-making practices of networks of antifeminist women on social media who identify as “traditional” or “trad” for short. Demonstrating how trad truth-making emerges in response both to the tensions inherent in right-wing nationalism and neoliberal postfeminism, it argues that the potential solution trad women pose depends on the ways they harness social media to limb public and private spaces and personal and political concerns. Paying particular attention to the entanglement of emotions and technical affordances, I use instances from my fieldwork in trad networks to frame their outreach as a form of truth management equally invested in carving out a space for their own (semi)public presence as in combatting the perceived dangers of feminism.
Determinants of CEO Investment Horizon. A Literature Review
Authors: Podukhovich Dmitry
Published: September 2023

This paper conducts a comprehensive literature review of the factors influencing the emergence of the CEO investment horizon problem – a preference for short-term investments over long-term ones. The root cause of this CEO issue, as in-dicated in existing literature, is often attributed to the CEO's personal risk attitude, shaped by factors like age, tenure, and cultural background.Numerous sources contributing to the short-term investment problem in public companies are described in the current academic literature. Prominent among these determinants are the challenges of quarterly reporting, the association of corporate performance with short-term metrics, market pressures, and the company's specific risk profile. A study by McKinsey & Company, focused on the short horizon problem, demonstrates that companies inclined toward short-term investments exhibit weaker fundamentals and performance. The consulting firm Ernst & Young has introduced the Long-term Orientation Index, offering a basis for cross-country comparison of decision horizons. In 2010, Antia and colleagues introduced a metric for measuring CEO decision horizons, which relies on CEO personal characteristics. Despite these efforts, a comprehensive literature review addressing the specificity of the CEO investment horizon problem and its dis-tinctions from the broader corporate investment horizon problem has been absent.This paper not only investigates the initial empirical exploration of the short investment horizon problem but also raises questions about its cross-country manifestations, its potential correlation with economic crises, and the relevant personal traits of CEOs for its study. Finally, the paper proposes various strategies to mitigate the CEO investment horizon problem within companies.
Locating Naturecultures

Published: September 2023

Building upon two collaborative exhibits created for the 4S (Society for Social Studies of Science) meetings in 2018 and 2019, this essay aims to question established modes of locating matters in STS and related fields. As these exhibits showed, Japan has been an active venue for anthropologists and STS scholars working with a diverse range of approaches and topics that may help us to rethink place and space beyond a humanist spatial politics of globalization. At the same time, science and technology in Japan has been a highly fruitful area for scholars located to understand the co-constitution of knowledges and worlds by tracing their multiple trajectories partly outside of English language research agendas. Using the online journal NatureCulture as a springboard for these explorations, we hope to contribute to the ongoing debates around situated methodological approaches. The journal is intended to be a medium that on the one hand brings young Japanese researchers into closer contact with related debates elsewhere, and on the other hand exhibits novel and challenging results of Japanese anthropology and science studies to a non-Japanese audience. A handful of themes (multiplicities, cosmopolitics, experimentation) from the journal will be reviewed here in order to further explore their potential in locating matters across, as well as beyond, physical and geographic boundaries.
Seabed in the Andes: Exploring “Splace” in Transnational STS
Authors: García-Deister Vivette
Published: September 2023

This commentary engages with the digital materials of STS in/through Turkey, Kenya, Japan, and Ecuador collected between 2018 and 2019, and with the collection of essays inspired by these materials. I use the notion of “splace” as an exploratory tool that challenges the division between space and place, and I also invite thinking about STS formations with geological formations I encountered on the Chilean Andes.

Transnational dialogues in STS matter and are at the heart of ESTS, exemplified by this issue. Two Original Research Articles, the first by Lucía Céspedes (2023) and the second co-authored by Gonçalo Santos, Naubahar Sharif, and Jack Linzhou Xing (2023) respectively, consider what is lost in translation—in the practice of astronomy in Argentina, and the translation of ‘STS’ in China’s academic institutions. The thematic collection, TRANSnationalizing STS, will take the reader through STS in Kenya (Okune and Mutuku 2023), Turkey (Alkan, Kaşdoğan, and Erol 2023), Japan (Mohácsi, Otsuki, and St. Pierre 2023), and Ecuador (Albornoz 2023), showcasing new modes and models of doing STS. The thematic collection brings these spaces and places together in enlightening ways, from the way in which the collection first emerged in the exhibitions of STS Across Borders, and Innovating STS through to a reflective interview published on STS-Infrastructures (Khandekar, Fortun, Kaşdoğan, and Okune 2023), and delightful engagements from Michael Fischer (2023a, 2023b, 2023c, 2023d, 2023e, 2023f) and Vivette García-Deister (2023). The latter two engagements provide the reader with insights into STS platforming and infrastructuring experiments. Venture into the STS-Infrastructures for another 73 pages of adjacent supplementary materials including archival writing, interviews, reflections and more. This issue also sees ESTS providing authors with multiple licensing options in our open access publishing model.

Stepped spillways have become increasingly popular due to their stability and ability to dissipate energy effectively. While previous studies have evaluated various aspects of stepped spillways, this paper specifically investigates the impact of step height on energy dissipation and flow characteristics. The study aims to analyze the flow and energy dissipation rates of stepped spillways with different step heights, providing valuable insights into the design and construction of such structures. To achieve this, a series of laboratory experiments were conducted using stepped spillway models of varying step heights. The models were subjected to various flow rates within a horizontal flume of 0.3 m width, with a non-dimensional discharge (yc/h) range of 0.14 to 3.5. The outcomes indicated that the model with a larger step height exhibited greater energy dissipation, up to approximately 28%, compared to the model with a smaller step height.

Tem-se por objetivo: analisar aspectos referentes a Síndrome de Burnout em professores da graduação em enfermagem e a sua relação com as Tecnologias de Informação (TICS).  A pesquisa é exploratória, descritiva, transversal e explicativa, de abordagem quantitativa, oriunda de uma tese de doutorado. A pesquisa foi realizada entre instituições de ensino superior pública e privada, ambas localizadas no município de João Pessoa-PB e Cabedelo-PB. Participaram da pesquisa 159 docentes de enfermagem, que responderam a um questionário sobre a Síndrome de Burnout e as TICS CAAE nº 50611115.1.0000.5188. Foi possível observar que os professores utilizam rotineiramente essas ferramentas em suas aulas, tal uso acaba por demandar mais tempo de planejamento e dedicação do trabalhador, uma vez que em sua grande maioria não se tem suporte adequado para a utilização dessas tecnologias no formato em que é exigido. Essa conjuntura acaba gerando cansaço, estresse, torna o trabalho mais difícil e acarreta em desmotivação do indivíduo pelo seu exercício profissional. Posto isso, é possível considerar que as TIC influenciam no adoecimento docente.

Published: September 2023

A pandemia da COVID-19 trouxe mudanças na rotina de todos, com a necessidade de adaptações para enfrentar os desafios tanto para clientes quanto para os profissionais da Medicina Veterinária. As medidas restritivas fizeram com que a produção, os investimentos e os consumos fossem abalados, havendo escassez de medicamentos e equipamentos. As restrições de circulação de pessoas e de isolamento social provocaram repercussões diretas no emprego e na renda da população, aumentando as desigualdades sociais. Objetivou-se em identificar o impacto para Médicos Veterinários no estado da Paraíba, durante a crise da saúde pública no período da pandemia da COVID-19. A pesquisa foi realizada a partir do direcionamento do questionário com os Médicos Veterinários que atuam em clínicas, consultórios, ambulatórios e afins, no estado da Paraíba-PB. Os dados coletados foram submetidos à análise, com a construção de gráficos e tabelas. O estudo foi aprovado pelo Comitê de Ética e Pesquisa (CEP). A maioria dos estabelecimentos veterinários se manteve aberto (83,8%); houve um aumento nos atendimentos em domicílio (44%) e principalmente nos atendimentos clínicos (66,2%). Um número significativo de médicos veterinários (85,3%) apresentou dificuldades em adquirir insumos. Observou-se que 66% dos participantes relataram melhorias no marketing nesse período e 44,1% necessitaram adquirir novos equipamentos; mesmo assim, 60,3% tiveram impacto financeiro para manter suas atividades. Em relação à presença da doença, 55,9% dos participantes tiveram COVID-19. Somente 2,9% dos médicos veterinários não tinham tomado vacina para o Coronavírus, e 82,4% afirmaram que se sentiram mais tranquilos para realizar suas atividades profissionais após a vacinação. Conclui-se que a pandemia da COVID-19 impactou negativamente a vida dos médicos veterinários da Paraíba em suas atividades profissionais e nos aspectos pessoais.

O preconceito relacionado ao peso e a autoimagem presente nos discursos dos estudantes e profissionais de saúde constitui-se como um grande entrave para as práticas de cuidado, uma vez que reflete em implicações negativas aos sujeitos. Desse modo, o presente estudo tem por objetivo analisar a autoimagem corporal e as atitudes negativas quanto a obesidade entre os universitários dos cursos de nutrição, enfermagem e farmácia de uma instituição pública. Trata-se de um estudo quantitativo, descritivo e transversal. Participaram 135 acadêmicos do Centro de Educação e Saúde, Cuité, Paraíba. Os principais instrumentos de coleta foram a Escala de Silhuetas Brasileira para adultos e a Escala de Atitudes Antiobesidade (AFAT). Dos entrevistados, 38,5% eram do curso nutrição, 32,6% de enfermagem e 28,9% de farmácia. Foram mais frequentes entre os estudantes nutrição, enfermagem e farmácia, nesta ordem, a insatisfação pela magreza e pelo excesso de peso. Quanto as atitudes negativas, entre todos os entrevistados, as médias mais altas foram sobre as crenças negativas e culpa ligadas aos sujeitos em condição de obesidade, principalmente entre os estudantes de enfermagem. As atitudes negativas na escala geral e nas dimensões ‘depreciação social e do caráter’ e ‘não atratividade física e romântica’ foram maiores entre os estudantes de nutrição.

Evaluating the Design of Service-Dominant Business Models: A Qualitative Method Rick Gilsing, Eindhoven University of TechnologyFollow Oktay Turetken, Eindhoven University of TechnologyFollow Baris Ozkan, Eindhoven University of TechnologyFollow Paul Grefen, Eindhoven University of TechnologyFollow Onat Ege Adali, Eindhoven University of TechnologyFollow Anna Wilbik, Maastricht UniversityFollow Frank Berkers, TNOFollow Abstract Background: Driven by factors such as digitization and rapid technological change, many contemporary organizations adopt a service orientation to sustain competitiveness and to improve their value propositions to customers. In doing so, organizations typically engage in collaborative service ecosystems to co-create value and exchange services, and conceptualize such collaborations using business models. The resulting models should be evaluated to support the development of service ecosystems and their long- term viability. Despite academic efforts on the evaluation of traditional, organization- centric business models, limited research is present supporting the evaluation of service- dominant business models, taking into account their key characteristics, such as service exchange and value co-creation in business networks. Method: Following a design science research methodology, we have iteratively designed a method addressing the qualitative evaluation of service-dominant business models, building on and integrating the theory on service-dominant logic, business model design and business model evaluation. To structure the steps of the design process, we leverage a situational method engineering approach, following a paradigm-based strategy. To evaluate the validity and utility our method, we have applied it to a real-life business case in the mobility domain, involving eight industry stakeholders in the process. Results: The method constitutes a set of guiding questions and a procedural description of their use, addressing the evaluation concerns of feasibility, viability, structural validity and robustness with respect to the service-dominant business model. The results of the evaluation demonstrate that the use of the method facilitates users to reflect qualitatively on design decision with respect the business model design and offers insights on its expected performance. Conclusions: This work contributes to extant research on service systems engineering and the instantiation of service-dominant logic, clarifying how service ecosystems can be evaluated through the business model concept and explicating how business models are impacted through service-dominant logic.

Abstract Background: Social media has grown into a prominent marketing and communication tool, and Instagram is a leader in this regard due to its distinctive supports for medial rich contents. Due to the challenges faced by Small-and-medium-enterprises (SMEs), they are suggested to embrace social media technology. Previous studies in Interactive value creation theory (IVF) indicated that SMEs-followers co-creation processes enable Instagram engagement. However, little is known of how to promote the value co-creation process via practical Instagram micro-practices that SMEs can employ regarding their constraints. This study is among the first to examine SMEs' practices for Instagram engagement via the process of value co-creation. Method: We collected data regarding Instagram engagements of 10 Australian SMEs in eight months period using Instagram API. Qualitative analysis is conducted based on 2110 contents in a Poisson regression model. Content analysis and time-series visualizations are employed to investigate the uniqueness of several outliners in the dataset. Results: Findings imply that SMEs should bank on @Tagging instead of #Hashtags to get more engagement as contents with @Tagging show higher levels of inclusiveness and trustworthiness. Also, customized postings for the loci-specific audience effectively encourage followers to participate in conversations, while commercial intensive posting style shows adverse effects due to its low level of credibility. Rich media contents would not necessarily reel in more engagement; the commitment and consistent postings amassed a considerable number of followers over time, leading to a higher engagement rate. Conclusions: This study confirmed the benefits of data scraping in building business intelligence and validate the IVF framework as the theoretical background to investigate the effectiveness of Instagram micro-practices. IVF should be considered in designing social media practices to enable SMEs and followers' collaborations for business value generation. This study provides extra interpretations of the interrelationships between IVF, visual-rich contents, and social media engagement.
An Explorative Dive into Decision Rights and Governance of Blockchain: A Literature Review and Empirical Study
Authors:   HU University of Applied Sciences Utrecht, Leewis Sam , Smit Koen ,   HU University of Applied Sciences Utrecht, Meerten John van ,   HU University of Applied Sciences Utrecht
Published: September 2023

Abstract Background: Blockchain technology and accompanying programmed protocols (smart contracts) offer disruptive opportunities for businesses, public institutions, society, and its citizens. However, blockchain is a relatively young research area: the number of publications available regarding blockchain did not begin to rise significantly until 2012, and certain fields of the blockchain domain remain to be explored. A similar situation exists with research into the governance of blockchain solutions focusing on decision rights: the limited number of theoretical and empirical contributions hinders the proper adoption of governance mechanisms in practice. Method: A mixed-method approach was conducted in which 1) a structured literature review, 2) semi-structured interviews, and 3) a focus group discussion were utilized to determine the current situation regarding decision rights in the context of blockchain governance. Results: The structured literature review resulted in a total of 23 relevant contributions. Those contributions were consolidated to serve as input for a total of twelve semi-structured interviews, and for a focus group session with five participants, who were not part of the interviewee pool. Using that approach, an overview of the concepts, relationships and mechanisms pertinent to decision rights was composed. Conclusions: Considered together, the results show that decision rights are often overlooked at the start of a blockchain project, where technical considerations are dominant in the discussion with stakeholders. However, research also points out that the longer it takes to address decision rights in a blockchain consortium, the more complex and costly it becomes to introduce governance mechanisms at a later stage. Another important conclusion is that consensus is currently lacking as to what constitutes blockchain governance and what part decision rights play in governance processes, in both theoretical and practical terms.

Abstract Background: The purpose of this paper is to explore the underlying challenges in the telehealth environment in India and Pakistan that impede the delivery of high-quality images between a patient and health care professional. Method: An exploratory study was conducted among healthcare professionals in India and Pakistan to assess their perceptions regarding image quality, which is used for the diagnosis and treatment decision making. This cross-sectional qualitative study used semi-structured interviews with healthcare professionals in both India and Pakistan. Results: The interviews were analyzed using a thematic analysis, which revealed three major themes. These themes being: ICT infrastructure and connectivity, expertise of persons taking images, and multiple transmission degrading image quality. Conclusions: Findings indicate that in both countries, the main underlying challenge is the lack of consistency in the network infrastructure between urban, rural and remote areas. Additionally, training patients to use hand-held devices to take high-quality images could hold the key to improving the reliability and, consequently, the quality of images transmitted between patients and health care professionals.

Published: September 2023

Abstract Background: In the current sensitive social environment, understanding why citizens voluntarily use social media to express their opinions, can be crucial in driving constructive social outcomes and avoiding perils like online disnformation and polarization. This study aims to identify the key technical affordances of social media that can potentially impact the political participation of its users. We then try to identify the dynamics of how these characteristics of social media influence different aspects of political participation activities taken up by citizens. Method: In phase one of the study, five focused group interviews were conducted among social media users to identify the affordances of social media at promote political participation. We use the results of this section to propose a research model based on Social Capital theory and Downs theory of political participation. We verify this model in the context of Facebook use by citizens of India. We collected the data using an online survey of 229 social media users and tested the model using the PLS-SEM technique. Results: The findings of content analysis of the interviews revealed the presence of four prominent affordances in the case of social media use for political participation: Association, Metavoicing, Visibility & Convenience. The result of model verification reveals that social capital created due to the technical affordances mentioned above effectively reduces the cost of participation, and more importantly, provides added benefits such as social recognition, expressive value, and other social rewards. Conclusions: The study concludes that specific affordances of social media significantly impact citizens’ social capital, perceived costs of participation, perceived benefits of participation, and in turn, impact their participation behavior. The role of social capital in online environment is analogous was crucial in leading to participation outcomes.

Nowadays, there are actual problems associated with destructive slope processes under the influence of gravity load. Indeed, gravitational slope processes, together with other erosion and tectonic processes, contribute a lot to the formation of the modern relief and at the same time very often complicate the rational using of the corresponding territory. Landslide processes can be distinguished among the most dangerous gravitational slope processes. These processes are characterized by widespread distribution and significant material losses and human casualties to which they lead. Due to its social importance and practical engineering significance, the problems of studying gravitational shear processes have a long history. Therefore, many works are devoted to these problems, but from another hand, the cases of strict mathematical and mechanical description and determination of certain quantitative mechanisms and criteria for the development of sliding gravitational processes have been considered in a rather limited way. In presented work on the base of variational finite-element method, we calculate the rotational deformation and failure criteria of a wide class of three-dimensional heterogeneous anticlinal geostructures under the gravity load conditions. The simulation results show that the shear deformation of anticlinal geostructures under the influence of gravity depends on the shape, size of the structure, and mechanical properties of the rocks that make up these geostructures. We have established that more compact geostructures are subjected to the smallest deformation. In the solid geostructures that retain elastic properties, the deformations are inversely proportional to the degree of rock stiffness, and a decreasing in the curvature radius of the geostructure leads to an inversely proportional increase in the deformation of the corresponding geostructure. We have shown that in order to maintain resistance to shear soil gravity failure, anticlinal geostructures cannot be completely composed of rocks softer than semi-solid dispersed soils. It was established that the resistance to shear gravity soil failure of heterogeneous anticlinal geostructures is mainly determined by the rigidity of the internal bearing rocks, while the influence of the stiffness of the external soft rocks is relatively insignificant and has a non-linear character.

Industrial computed tomography (CT) has seen widespread adoption as an inspection technique due to its ability to resolve small defects and perform high-resolution measurements on complex structures. The reconstruction of CT data is usually performed using filtered back-projection (FBP)
methods, such as the Feldkamp-Davis-Kress (FDK) method, and are selected as they offer a good compromise between reconstruction time and quality. More recently, iterative reconstruction algorithms have seen a resurgence in research interest as computing power has increased. Iterative reconstruction
algorithms, such as the algebraic reconstruction technique (ART), use a reconstruction approach based on linear algebra to determine voxel attenuation coefficients based on the measured attenuation of the sample at the detector and calculation of the ray paths traversing the voxel grid. This
offers a more precise model for CT reconstruction but at the cost of computational complexity and reconstruction time. Existing ART implementations are based on the 2D weighting models of the binary integral method (BIM), line integral method (LIM) and area integral method (AIM). For full
3D reconstruction, BIM and LIM only offer approximations leading to numerical inaccuracies. AIM for 2D reconstruction is mathematically exact but considers the divergent nature of a fan beam for 2D only. For a full 3D volumetric reconstruction, the X-ray cone beam is divergent in all directions
and therefore AIM cannot be applied in its current form. A novel voxel weighting method for 3D volumetric image reconstruction using ART and providing a mathematically exact fractional volume weighting is introduced in this paper and referred to as the volume integral method (VIM). A set of
algorithms is provided based on computer graphics techniques to determine ray/voxel intersections with volume reconstruction computed based on the divergence theorem. A set of experimental configurations is developed to provide a comparison against existing methods and conclusions are provided.
Optimisation is achieved through graphic acceleration.

Misclassified nonearthquake seismic events like quarry blasts can contaminate the earthquake catalog. The local earthquakes sometimes have similar features as the quarry blasts, which makes manual discrimination difficult and unreliable. Thus, we propose to use the compact convolutional transformer (CCT) and capsule neural network to discriminate between earthquakes and quarry blasts. First, we extract 60 s three-channel seismograms, that is, 10 and 50 s before and after the P-wave arrival time. Then, we transform the time-series data into a time–frequency domain (scalogram) using the continuous wavelet transform. Afterward, we utilize the CCT network to extract the most significant features from the input scalograms. The capsule neural network is utilized to extract the spatial relation between the extracted features using the routing-by-agreement approach (dynamic routing). The capsule neural network extracts different digit vectors for the earthquake and the quarry blast classes, allowing a robust classification accuracy. The proposed algorithm is evaluated using the seismic dataset recorded by the Egyptian Seismic Network. The dataset is divided into 80% for training and 20% for testing. Although the dataset is unbalanced, the proposed algorithm shows promising results. The testing accuracy of the proposed algorithm is 97.31%. The precision, recall, and F1-score are 97.23%, 98.83%, and 98.02%, respectively. In addition, the proposed algorithm outperforms the traditional deep learning models, for example, convolutional neural network, ResNet, Visual Geometry Group (VGG), and AlexNet networks. Finally, the proposed method is demonstrated to enjoy a high-generalization ability through a real-time monitoring experiment.
