Emerging principles of primary cilia dynamics in controlling tissue organization and function.

Primary cilia project from the surface of most vertebrate cells and are key in sensing extracellular signals and locally transducing this information into a cellular response. Recent findings show that primary cilia are not merely static organelles with a distinct lipid and protein composition. Instead, the function of primary cilia relies on the dynamic composition of molecules within the cilium, the context-dependent sensing and processing of extracellular stimuli, and cycles of assembly and disassembly in a cell- and tissue-specific manner. Thereby, primary cilia dynamically integrate different cellular inputs and control cell fate and function during tissue development. Here, we review the recently emerging concept of primary cilia dynamics in tissue development, organization, remodeling, and function.

Effectiveness of Tornado Physics Enrichment Book to Increase Science Literacy of High School Students

Scientific literacy is a need and learning goal in the industrial era 4.0. Indonesia's low scientific literacy is an urgent problem. There are many ways that can be used in learning to hone scientific literacy, including choosing sources and teaching materials that are integrated with natural disaster environmental. In this research, scientific literacy was sharpened in physics learning through the use of a knowledge enrichment book entitled Tornado. In this enrichment book, the discussion of tornadoes is presented from a physics perspective including the concepts of energy, heat, fluid dynamics and global warming. The aim of this research is to increase students' scientific literacy by using physics enrichment books on the theme of the tornado disaster. This research uses an experimental research method in the form of a quasi-experimental design with a one-group pretest-posttest design. The results of the trial of 60 students from SMAN 13 Padang and SMAN 2 Padang Panjang showed that the use of enrichment books was able to increase students' scientific literacy, with an average pretest scientific literacy of 46 and an average posttest of 87, and an N-gain of 0.76. These results indicate that the use of tornado physics enrichment books is effective in increasing students' scientific literacy.

The objective of this study is to provide a comprehensive, up-to-date overview of leadership and EI research in terms of publication activity, top journals, top articles, and top countries. A total of 184 documents were extracted from the Scopus database and included in the VOS viewer software for bibliometric analysis such as keyword co-occurrence analysis and co-authorship analysis. EI began to emerge at the end of the 20th century. The field witnessed its most productive phase from 2006 to 2014. Furthermore, the analysis revealed that after 2020, the field once again gained popularity and emerged as a high-potential research domain. "Leadership and Organizational Development Journal" and "Journal of Management Development" rank as the most productive journals; Ashkanasy, N.M., and Humphrey, R.H., have the highest number of publications; and the US (n = 81) is the most prominent country in producing articles in this domain. Overall, this research provides a comprehensive understanding of the dynamical concepts of EI and leadership. Corporations can employ a range of ways to increase leadership skills by harnessing EI. To begin, incorporating EI assessments into leadership development programs can aid in the identification of potential leaders with high EI skills. Consequently, providing personalized training and mentorship can increase leaders' reflection, empathy, and communication skills.

Bodily-Affective Aspects of Phenomen in Malevich’s Suprematism

The study addresses some aspects of Suprematist theory of perception, allowing to investigate the structure of Suprematist phenomenon in the context of ontology, socio-political and religious-mystical works of K. Malevich. The aim of the paper is to present Malevich’s theory of perception in the framework of enactivism. Namely, the article focuses on the theory of social affordances, which today is widely used in design, game development and other everyday practices. The author refers to Malevich’s theoretical and sociopolitical essays, as well as to the commentary literature. Although Suprematism represents a well-researched tradition in art theory, the author stress the need for a follow-up study of Malevich’s theoretical essays in the contemporary context of philosophy of consciousness. The author also emphasizes the relevance of Suprematist philosophy for today’s way of thinking. For the most authentic presentation of Malevich’s ideas I use the phenomenological and hermeneutical method on a par with elements of the ecological approach in psychology and enactivism in the philosophy of consciousness. Consequently, the theory of affordances an effective and natural unification of all the aspects discussed above. The study shows the affinity of Malevich’s ideas to this theory. The author focused on the thesis of feeling as the goal of the expressive act of art. As one could see, Kazemir Malevich always emphasized the bodily-affective dimension of art, and in this sense he participated in a global cultural-historical shift in our conception of the essence of art. Since then, art has ceased to be elitist, but has instead inherited everyday practices. Thus, Malevich speaks of a new art that suits the man of the new world, the Soviet citizen. In this context, I relate the idea of affordance, which means the creation of a feeling-opportunity for subjective action (agency), to the artistic act whose goal, according to Malevich, is the creation of an emotional body-affective feeling. I defend the theory of social affordances, explaining the mechanism of social interaction, as the most adequate model for explaining Suprematism. As a result, based on the already developed concept of bodily-affective dynamics, I show how visionary and creative Malevich was, and how his ideas contribute to the development of a theory of social, emotional affordances.

Receptions of Kant’s Philosophy in Russian Empiriocriticism

The article analyzes the influence of Kantian philosophy on the problems and development of Russian empiriocriticism. It is shown that the critical pathos of Kant’s philosophy, as well as his call for intellectual honesty in philosophy, was appreciated first of all. Relying on Kant, Russian empiriocritics proved the inconsistency of metaphysics in both its religious and materialistic forms. In addition, the teachings of the founders of empiriocriticism, E. Mach and R. Avenarius, were also criticized because some dogmatic assumptions were found in them. Attempts to eliminate these assumptions resulted in a dynamic concept of experience, based on which the concepts of empiriomonism (A. Bogdanov), empiriosymbolism (P. Yushkevich), scientific philosophy (V. Lesevich), positive philosophy of life (S. Suvorov), positive aesthetics (A. Lunacharsky), ethics of mutual joy (A. Bogdanov) and many others were developed. Special attention was paid to the analysis of the “thing-in-itself” since this very concept of Kantian philosophy was used by G. Plekhanov to justify “orthodox” Marxism. Russian empiriocritics opposed Plekhanov’s identification of the “thing in itself” and the material object, arguing that the concept of matter is a metaphysical assumption and, for this reason, cannot contribute to refuting dualism and Kantian “agnosticism.” From the monistic point of view, the “thing-in-itself” should be understood on the basis of experience as a necessary form of its organization. According to Bogdanov, there is nothing a priori in the “thing-in-itself”; this idea appeared as a result of substituting the known for the unknown and expressed a process rather than essence. Kant’s aesthetics and moral philosophy were also actively discussed in Russian empiriocriticism. The interpretation of beauty as “expediency without purpose” was extended to the fundamental principle of the “aesthetic worldview,” which gave credibility to the doctrine of the ideal, the practice of social construction, etc. As a result of the polemic with the ethics of compassion, of which Kant was considered the most authoritative defender, an alternative ethic of mutual joy was created. Thus, the influence of Kantian philosophy on Russian empiriocritics was complex and contributed to the development of new ideas.

Student Engagement

Increasing numbers of international students bring their different cultures, languages, and educational backgrounds to higher education, and they expect their experiences and interactions with higher education institutions to be rewarding journeys. A key issue - the dynamic and multifaceted concept of student engagement as an important indicator of the quality of the student experience - has yet to be thoroughly addressed in conceptual discussions and empirical studies with international students, and thus deserves more attention. This paper aims to conceptualise this buzzword, i.e., 'student engagement', in higher education, by embracing the complexity and diversity of international students' experiences to enable a deeper understanding of international students' experiences and needs, and to inform research and practice that considers all stakeholders through questions and suggestions.

AdaDeepStream: streaming adaptation to concept evolution in deep neural networks

Typically, Deep Neural Networks (DNNs) are not responsive to changing data. Novel classes will be incorrectly labelled as a class on which the network was previously trained to recognise. Ideally, a DNN would be able to detect changing data and adapt rapidly with minimal true-labelled samples and without catastrophically forgetting previous classes. In the Online Class Incremental (OCI) field, research focuses on remembering all previously known classes. However, real-world systems are dynamic, and it is not essential to recall all classes forever. The Concept Evolution field studies the emergence of novel classes within a data stream. This paper aims to bring together these fields by analysing OCI Convolutional Neural Network (CNN) adaptation systems in a concept evolution setting by applying novel classes in patterns. Our system, termed AdaDeepStream, offers a dynamic concept evolution detection and CNN adaptation system using minimal true-labelled samples. We apply activations from within the CNN to fast streaming machine learning techniques. We compare two activation reduction techniques. We conduct a comprehensive experimental study and compare our novel adaptation method with four other state-of-the-art CNN adaptation methods. Our entire system is also compared to two other novel class detection and CNN adaptation methods. The results of the experiments are analysed based on accuracy, speed of inference and speed of adaptation. On accuracy, AdaDeepStream outperforms the next best adaptation method by 27% and the next best combined novel class detection/CNN adaptation method by 24%. On speed, AdaDeepStream is among the fastest to process instances and adapt.

Understanding character naming in Khaketla’s Mosali a Nkhola: a literary onomastic analysis

This article aims to understand Khaketla’s intent in naming the characters in Mosali a Nkhola. As one of its key features, a novel has characters whose main purpose is to carry readers through the journey the author proposes for them. Characters, like people in real life, bear names that not only help identify them, but also play a vital role in the development of the theme in a literary text. The author makes assumptions about certain things and relies on them when selecting names for the characters. Through character naming, the author blends reality and artistic features to attain credibility. This, therefore, indicates that in literature, as in real-life contexts, names are not just tags, but they carry particular meanings. Using literary onomastics as an analytical tool, the article explores the names of the characters in Mosali a Nkhola to find out their meanings and significance in the development of the theme of the novel. The findings reveal Khaketla’s creative skill in naming in that the names are symbolic of Basotho history, culture and tradition. They also represent the traditional and modern philosophies, bringing out the concept of cultural dynamism in the text.

Mitigation of deceleration-phase Rayleigh–Taylor instability growth in inertial confinement fusion implosions

Rayleigh–Taylor growth during shell deceleration is one of the main limiting factors for target performance in inertial confinement fusion implosions. Using analytical scaling laws and hydrodynamic simulations, we show that such amplification can be mitigated by reducing the initial mass density in the central target region. The perturbation growth reduction is caused by a smaller hot-spot convergence ratio during deceleration, increased density scale length, and enhanced ablation stabilization. The required central density reduction can be achieved using the dynamic shell formation concept.

Quality is a dynamic concept, due to the demands of consumers in relationto the development of areas of activity and technical-scientific progress.

Fractal concepts and recognition: Hegelian intersectional feminism

ABSTRACT Feminists have long been aware that the notion of women is problematic and using it uncritically without further qualifications leads to exclusions. In the article, I argue that the source of these problems lies in the understanding of concepts as static and clearly defined. I deploy Hegel’s idea of syllogism to define dynamic concepts, which I term ‘fractal concepts’ because of their complexity and constant development. In such structures the balance between the universal, the particular and the individual is maintained and, consequently, every woman is essential for the definition of such a non-essentialist notion of women. I propose that an epistemological interpretation of the Hegelian idea of recognition can be used to describe the development of fractal concepts in the confrontation of different perspectives. It also explains the obstruction of this process by the desire for domination and control, which results in the appropriation of group identities by their privileged members. I situate the logical and political framework developed in the paper in the context of feminist controversies around the concept of woman and argue that it provides us with a comprehensive account of intersectionality as well as an explicative solution to the regress problem.

THE DYNAMIC CONCEPTION OF THE SOCIAL IN THE PHILOSOPHY OF CORNELIUS CASTORIADIS

The article presents a reconstruction of the dynamic conception of the social in the philosophy of Cornelius Castoriadis. A meticulous study of the philosopher’s most important works reveals, on the basis of various ideas about society and politics, the original version of his integral conception of the social. The reconstruction of this conception required a four-step study: (1) an analysis of his critique of “naïve realism” in the perception of social life; (2) an analysis of the method of revealing a symbolic component of social “things” in the interpretation of social institutions as functional-symbolic networks; (3) a study of the thematization of the virtual dimension of social life (Castoriadis’s construction of the metaphoric ontology of the “magma” of social imaginary significations, his perception of society as a dynamic (“social-historic”) formation, an elucidation of the duality of establishing and established); (4) an analysis of the way of a justification of a political project of autonomy. Our reconstruction demonstrates that the idea of autonomy is not a consequence but a cause of Castoriadis’s dynamic conception of the social. Nevertheless, in the context of the notion of “multiple modernities”, the idea of autonomy, being a key characteristic of “modernity”, can be understood not as universal content but as a universal form. The regulatory horizon of “politics” (of the project of autonomy) is determined from the reverse — depending on what is identified as heteronomy in a given set of concrete circumstances. The interpretation we propose will allow us to proceed more consistently from the principle of the diversity of “modernities”. It seems, also, that Castoriadis’s position itself is characterized by two “defects”: first, his conception of the social-historical world is based on the metaphoric ontology of the “magma”, and, second, the “philosophy of autonomy” is dualistic.

Enabling Protection Against Data Exfiltration by Implementing ISO 27001:2022 Update

The risk of data theft has increased significantly over the past years. As a consequence, overwhelming damage is caused to institutions and private persons, respectively. Even the widespread ISO standard 27001 was updated recently in October 2022 to integrate data exfiltration aspects. Corresponding new security controls have been introduced. In this paper we review the ISO 27001:2022 with respect to data exfiltration and come up with recommendations on how recently integrated ISO 27001:2022 controls can be used in an operational environment. Based on that, we introduce and demonstrate the effectiveness of a proactive and dynamic concept by integrating a simulation cycle into the Information Security Management System (ISMS) and using cyber threat intelligence to provide us with information about current threats. We provide a prototype for the threat simulation cycle based on a smart combination of established and widely accepted cyber defence tools. Within our evaluation we show the feasibility of our targeted and dynamically configurable simulation of data exfiltration threats and thus support to thwart the actual cyber-attacks in advance. In all we contribute to prevent (or at least make it significantly more difficult) the threat of data exfiltration. Dynamic, threat aware and preventive cyber-defence is our objective, and we provide an updated concept which integrates conclusively into an ISO 27001:2022 compliant ISMS.

Lift and Drag Analysis of NACA 1412 Airfoil Using Unstructured Mesh

Abstract: This research paper gives insight to the analysis of NACA 1412 airfoil. The airfoil is the two-dimensional cross section of the aircraft’s wing. The aircraft flies due to generation of the lift, this lift is caused by the pressure difference on the upper and lower surface of the airfoil. The pressure on the lower surface is greater than the pressure on upper surface which provides a lift to the airfoil. We are going to see the airfoil’s behaviour in incompressible flow at different angles of attack with constant velocity. In this research, we are going to use the Ansys software to do the analysis. This research is based on the computational fluid dynamics concepts. At the end, we will see how the lift and drag changes at different angles of attack and some graphical results from the research.

Perceived self-care ability among patients with stroke: Concept analysis

Purpose: PSCA (Perceived Self-Care Ability) is an important factor in the management of chronic diseases. However, there is no clear consensus over the definition of this concept among patients with stroke. The aim of this study was to analyze the concept of PSCA among patients with stroke and provide a clear definition for it. Methods: This concept analysis was conducted using Walker and Avant’s eight-step approach. Relevant articles, theses, and books published in English or Persian between 1987 and 2021 were reviewed. Findings: PSCA is a subjective and dynamic multidimensional concept with self-care agency, self-care ability, self-management, and fluctuating over time. Attributes which is affected by Perceptual and cognitive stability, psychosocial factors, health literacy, and sociocultural and economic contexts. The consequences include effective coping, satisfaction with life, prevention of adverse complications, continuity of care, and reduced healthcare costs. Conclusions: Defining the PSCA in stroke survivors makes them more likely to live a better and more independent life. With an increasing prevalence of chronic diseases worldwide, defining the concept of PSCA in stroke patients is essential to design appropriate interventions aimed to promote patients’ active role in managing chronic diseases. Nurses’ adequate knowledge about PSCA helps them develop more effective nursing interventions, discharge plans, and rehabilitation programs. The results of this concept analysis can be a basis for designing a tool to measure perceived self-care ability of stroke patients in the chronic stage of the disease.

Temporal Dynamic Concept Modeling Network for Explainable Video Event Recognition

Recently, with the vigorous development of deep learning and multimedia technology, intelligent urban computing has received more and more extensive attention from academia and industry. Unfortunately, most of the related technologies are black-box paradigms that lack interpretability. Among them, video event recognition is a basic technology. Event contains multiple concepts and their rich interactions, which can assist us to construct explainable event recognition methods. However, the crucial concepts needed to recognize events have various temporal existing patterns, and the relationship between events and the temporal characteristics of concepts has not been fully exploited. This brings great challenges for concept-based event categorization. To address the above issues, we introduce the temporal concept receptive field, which is the length of the temporal window size required to capture key concepts for concept-based event recognition methods. Accordingly, we introduce the temporal dynamic convolution (TDC) to model the temporal concept receptive field dynamically according to different events. Its core idea is to combine the results of multiple convolution layers with the learned coefficients from two complementary perspectives. These convolution layers contain a variety of kernel sizes, which can provide temporal concept receptive fields of different lengths. Similarly, we also propose the cross-domain temporal dynamic convolution (CrTDC) with the help of the rich relationship between different concepts. Different coefficients can help us to capture suitable temporal concept receptive field sizes and highlight crucial concepts to obtain accurate and complete concept representations for event analysis. Based on the TDC and CrTDC, we introduce the temporal dynamic concept modeling network (TDCMN) for explainable video event recognition. We evaluate TDCMN on large-scale and challenging datasets FCVID, ActivityNet, and CCV. Experimental results show that TDCMN significantly improves the event recognition performance of concept-based methods, and the explainability of our method inspires us to construct more explainable models from the perspective of the temporal concept receptive field.

Interpreting the Galway Hooker: Ecomuseology, Living heritage and sustainable heritage Management

ABSTRACT This article explores the Galway Hooker’s history, cultural heritage, and interpretive potential as an iconic workboat and fishing vessel rooted in Claddagh, a historical fishing village in Galway City. It examines the work of the Galway Hooker Sailing Club and their restoration of one boat, known as Loveen. By contextualizing the Club’s work within a living heritage framework, it advocates for an ecomuseum as an interpretative approach. Ecomuseology, a dynamic concept, focuses on preserving local cultural heritage and promoting sustainable development across social, environmental, and economic dimensions. This study combines desk research with fieldwork, including interviews with Sailing Club members.

The Entanglements of Matter, Mind, and Meaning: Novalis’s “Elastic Mode of Thinking”

This article explores the methodological, aesthetic, and ecological implications of Novalis’s dynamic conception of matter, called “original elastic fluid.” By elucidating a set of this fluid’s generative and performative capacities, Novalis explains the non-teleological and contingent emergence of natural objects and organic forms as well as mental figures and poetic genres. This article argues that Novalis’s model of a “dynamic materialism” resonates with recent new materialist discourses that emphasize the agency of inorganic matter. More specifically, Karen Barad’s “material-discursive” approach, derived from quantum phenomena that suggest the inseparability of meaning and matter, is comparable to the ways in which Novalis draws on dynamic laws of fluidity to develop an “elastic mode of thinking” and a Romantic conception of prose with a characteristically loose rhythmic structure. A reading of Die Lehrlinge zu Sais as an example of this prose form sheds new light on the entangled relationship between mind and nature and “ecopoetic” approaches to nature.

Analysis of dynamic methods for calculating NPP building structures

Introduction. The present article concerns the seismic performance of various building structures, including NPP objects. The provided materials generalize the results of the author’s longstanding work connected with the dynamics of building structures.Aim. To analyze the seismic performance of various building structures, including NPP objects, and represent the author’s material on the dynamics of building structures.Materials and methods. The presented materials include a definition of the dynamics concept, computational modeling of dynamic processes, main correlations of dynamic analysis methods, and a description of impacts (accelerograms). In addition, the concepts of resonance and vibration diagnostics in the dynamic analysis, assessment of the building strength and stability, as well as the description of applied software systems are provided. Some of the presented materials are characterized by the scientific novelty. The following methods were used in the study. The method of nonclassical modal superposition for determining the response of a structure under dynamic impacts together with floor response spectra were presented by the author at the ABAQUS (SIMULIA) International Conference in Barcelona, 2011. The essence of the method consists in the reliable account for a “soil” damper, modeling the energy outflow into the soil during the vibrations of a building, which ensures reliable results. A fundamental solution for accounting the ductility of the foundation slab under seismic impacts was applied. This method ensures the seismic response of the structure to be reliably determined, as well as the floor response spectra to be obtained in the conditions of the aircraft crashing for buildings, whose impact on the equipment is transmitted through the foundation slab. Additionally, the method of accounting the dynamic characteristics of building fragments (floor/ wall), obtained using the vibration diagnostic results, was applied to verify computational models, as well as to analyze the strength and floor response spectra. The appendix includes the realistic test problem of the seismic analysis, developed by the author.Results. The provided materials generalize the results of the author’s longstanding work in the field of NPP building structures. In addition to the scientific novelty, the materials are widely applied in the development of NPP designs both in the Russian Federation and abroad.Conclusion. The materials, presented in the article, can be used to prepare the “Introduction to Dynamics” lecture course, including, for newcomer countries that are at the beginning of the nuclear facility (NF) construction.

STUDY OF WIND RATE MEASUREMENT IN A VENTURI TUBE SYSTEM EQUIPPED WITH TWO WATER FILLED OPEN MANOMETERS

Various types of physical phenomena are experienced by the wind when it passes through a venturi tube system equipped with two open manometers filled with water. Its theoretical studies lead to 3 equation types of theoretical wind speeds that are unique. Experimental testing of each type of equation as a measurement method is significant to see the suitability level with the concept of fluid dynamics, the precision level, and the accuracy level. The research aims to determine the level of suitability with the fluid dynamics concept, the precision level, and the accuracy level. The research method is an experiment using equipment at the Bandung State Polytechnic Physics Laboratory. The research shows that: The suitability level of the three method measurement results is consistent with the concept of fluid dynamics; The highest level of precision and accuracy is produced by measurement method A, followed by method B, and the lowest by method C; All slopes of the linear curve mean wind speed ( ) is negative, 83.3 % of absolute uncertainty (AU) < 0 (negative), and 83.3 % of relative uncertainty (RU) > 0 (positive); The determination level of va by the diameter variable (d) and the electrical resistance (R) is in a strong category, the determination level of AU by the variable d is in the moderate category but with the variable R is in the weak category and then the weak category for the determination level of RU by the variable d and with the variable R.
