The reciprocity of skeletal muscle and bone: an evolving view from mechanical coupling, secretory crosstalk to stem cell exchange.

Introduction: Muscle and bone constitute the two main parts of the musculoskeletal system and generate an intricately coordinated motion system. The crosstalk between muscle and bone has been under investigation, leading to revolutionary perspectives in recent years. Method and results: In this review, the evolving concept of muscle-bone interaction from mechanical coupling, secretory crosstalk to stem cell exchange was explained in sequence. The theory of mechanical coupling stems from the observation that the development and maintenance of bone mass are largely dependent on muscle-derived mechanical loads, which was later proved by Wolff's law, Utah paradigm and Mechanostat hypothesis. Then bone and muscle are gradually recognized as endocrine organs, which can secrete various cytokines to modulate the tissue homeostasis and remodeling to each other. The latest view presented muscle-bone interaction in a more direct way: the resident mesenchymal stromal cell in the skeletal muscle, i.e., fibro-adipogenic progenitors (FAPs), could migrate to the bone injury site and contribute to bone regeneration. Emerging evidence even reveals the ectopic source of FAPs from tissue outside the musculoskeletal system, highlighting its dynamic property. Conclusion: FAPs have been established as the critical cell connecting muscle and bone, which provides a new modality to study inter-tissue communication. A comprehensive and integrated perspective of muscle and bone will facilitate in-depth research in the musculoskeletal system and promote novel therapeutic avenues in treating musculoskeletal disorders.

Participatory ex-ante impact assessment for interactive research and development in agriculture and food systems

ABSTRACT Drawing upon literature from both impact assessment of development projects and agricultural research, the aim of this article is to analyse the pilot testing of a new multi-dimensional assessment framework for defining and evaluating the societal impact of agricultural research and corresponding education. The research approach involves an action research effort of pilot testing in three case studies from three different countries. The framework assumes a systems view, understands impact as socially embedded, and adopts the concepts of contribution and productive interactions rather than cause-and-effect attribution. The emerging experiences include developing both project-specific and universal indicators; gauging impacts at different levels and sustainability dimensions; handling the issues of attribution and time frame; and the role of stakeholder involvement. The results have the potential to support the development of a new role for impact assessment, by enabling principal actors in research and higher education institutions to take responsibility for contributing to concrete and demonstrable sustainability changes in society.

Voltage-controlled finger friction behavior for immersive tactile experience in aqueous environment

To mimicking fingers perceiving the physical world, researchers developed tactile devices to establish a correlation between real and virtual world. This study proposed a new finger friction modulation method based on voltage-controlled technique in aqueous environment. Under continuous or alternate voltages applied to TC4 plate, the effects of NaCl, KCl and CaCl2 on finger friction were characterized with different concentrations. The finger friction was reversibly modulated by the voltages with the maximum friction variation of 110%. This modulation is attributed to the adsorption of OH-, bubbles effect and formation of passive film which affected the boundary lubrication performance of finger-TC4 interface. This study provides a new surface haptics concept for the underwater human-computer interaction or immersive virtual reality haptic technology.

Role of social media influencers on marketing of sustainable hotels: gratification and the parasocial interaction perspective

ABSTRACT Based on the concepts of gratification and parasocial interaction (PSI), we explore the effect of social media influencers on consumer behaviors in the marketing of sustainable hotels on Instagram (IG). We derive insights from 792 valid responses of consumers residing in the U.S. and analyze their behaviors and perceptions as related to both sustainable hotels and the leveraging of Instagram as a marketing tool. Through structural equation modeling, the findings of this study show that gratification increases consumer community commitment to IG through PSI. Moreover, PSIs positively influence consumer behaviors, such as booking intention, word of mouth (WOM) and electronic word of mouth (eWOM), through IG community commitment. Finally, the expertise of social media influencers strengthens consumer commitment to the IG community. The trustworthiness of social media influencers also strengthens consumer booking intentions.

Interaction between Pipe Rotation and Cuttings Transport in Extended-Reach Drilling: Mechanism, Model, and Applications

Summary High drag and torque on drillstring and difficulty in hole cleaning are two major challenges in extended-reach drilling, and these two challenges are usually coupled with each other. However, previous studies considered the drillstring mechanics and hole cleaning as two relatively independent issues and studied them separately, which cannot fully reveal the complex mechanisms of pipe sticking and obtain proper drilling parameters to ensure hole cleaning and reduce drag and torque. To solve this problem, in this paper we present the concept of pipe-cuttings interaction and elaborate on the two interaction mechanisms, which are the effect of pipe rotation on cuttings transport and the effect of cuttings distribution on pipe load. Second, we introduce the stirring diffusion factor and pipe-cuttings contact stress to quantify the pipe-cuttings interaction, and we obtain their mathematical expressions through nonlinear regression of numerical simulation results. Third, we establish the mechanical pipe-cuttings interaction model by modifying and combining the tubular mechanical model and the cuttings transport model. Finally, we validate the interaction model and apply it to a case study of extended-reach drilling in the South China Sea. The results show that the interaction model is of high prediction accuracy and is superior to the conventional tubular mechanical and cuttings transport models because the interaction between pipe rotation and cuttings transport is sufficiently considered. The problem of poor hole cleaning for a 12¼-in. section is serious, and pipe sticking occurs frequently for the extended-reach well in the case study because the stationary bed height is more than 10% in actual drilling. It is usually difficult to ensure hole cleaning of a 12¼-in. section by only optimizing a single parameter of rate of penetration (ROP), flow rate, or rotational speed, but optimizing two of the parameters at the same time can achieve better results. Lastly, we establish a recommended chart of drilling parameters, which can aid engineers in making comprehensive recommendations on drilling parameters.

Making sense of doing science: on some pragmatic motifs guiding the enactive approach to science

AbstractIn this article, I will explore the enactive approach to science and the pragmatic motifs that guide it. In particular, in the first half of the article, I will discuss to what extent enactivism can be seen as a philosophy of nature, and by comparing it with Sellars’s interpretation of the conflict between the manifest and the scientific image of humans in the world, I will focus on the view of nature that enactivism defends. In the second part, I will compare the enactive approach with Dewey’s conception of the organism-environment interaction by focusing on the underlying similarities between their views of evolution and their way of seeing science as the most sophisticated expression of an organism’s sense-making.

Disrupted inter-brain synchronization in the prefrontal cortex between adolescents and young adults with gaming disorders during the real-world cooperating video games

BackgroundGaming disorder (GD) and hazardous gaming (HG) have a high incidence among adolescents and young adults and have caused various negative consequences. Interpersonal interaction deficits are closely related to GD and HG, however, the underlying brain mechanisms are still unclear. MethodsThe current study recruited 46 healthy subjects and 32 subjects with GD/HG. Gaming time and frequency, gaming disorder risks, life events, strengths, and difficulties were measured with scales. Subjects were randomly paired into 12 HC-HC dyads, 15 GD/HG-HC dyads, and 7 GD/HG-GD/HG dyads and in pairs completed a real-world cooperating video game — “Tied Together” with functional near-infrared spectroscopy hyperscanning recording in the prefrontal cortex. The inter-brain synchronization in each region of the PFC between dyads was calculated by wavelet to transform coherence to measure brain-to-brain synchronization. ResultsWe found subjects with GD/HG reported higher risks of gaming. The highest IBS in the left dorsolateral prefrontal cortex significantly decreased in the GD/HG-HC and GD/HG-GD/HG dyads compared with healthy controls. A decreasing highest IBS of the left dlPFC was related to a decreasing level of peer problems. LimitationsWe declare limitations of age gaps of samples, undistinguishing GD from HG, use of sub-samples, and the broad concept of interpersonal interaction. ConclusionsThe current study found a decreased highest IBS in the left dlPFC among adolescents and young adults with gaming diseases. It may provide new prevention and treatment insights into gaming disorders targeting disrupted interpersonal interaction.

Evaluation of the Development Level of Integration of Culture and Tourism in China’s Provinces under the Perspective of Spatial Interaction and Study of Influence Paths

In the new stage of the deep integration of culture and tourism, fully exploring its mechanism of action, spatial connection, and path of influence will be of great significance to the sustainable development of the integration of culture and tourism. In this paper, we analysed the mechanism of integration of culture and tourism with the help of systems theory, introduced the concept of spatial interaction to construct a new measurement model of integration of culture and tourism, and conducted empirical analyses with Chinese provinces as the target. We found that in the last decade, the tourism industry has been dominant, and most of the industrial elements have been clustered towards it. The centre of the spatial interaction network of culture and tourism is located in the area of the “North China Plain—Middle and Lower Yangtze River Plain” and moves towards the southwest over time. The northwestern and northeastern zones have become “desert zones” in the spatial interaction network of culture and tourism. The level of integration of culture and tourism peaked in 2018, with East China having a chronically higher level of integration. In addition, the deep integration of culture and tourism can be promoted through the combination of new development philosophies.

Mimicking the Shape and Function of the ClC Chloride Channel Selective Pore by Combining a Molecular Hourglass Shape with Anion-π Interactions.

ClC is the main family of natural chloride channel proteins that transport Cl- across the cell membrane with high selectivity. The chloride transport and selectivity are determined by the hourglass-shaped pore and the filter located in the central and narrow region of the pore. Artificial unimolecular channel that mimics both the shape and function of the ClC selective pore is attractive, because it could provide simple molecular model to probe the intriguing mechanism and structure-function relevance of ClC. Here we elaborated upon the concept of molecular hourglass plus anion-π interactions for this purpose. The concept was validated by experimental results of molecular hourglasses using shape-persistent 1,3-alternate tetraoxacalix[2]arene[2]triazine as the central macrocyclic skeleton to control the conductance and selectivity, and anion-π interactions as the driving force to facilitate the chloride dehydration and movement along the channel.

TÜRKİYE’DE AFET YÖNETİMİ VE YENİ BİR MODEL ÖNERİSİ: KARDEŞ ŞEHİR AFET YÖNETİM MODELİ

The concept of interaction, which has found more space in international relations with globalization, has also expanded the field of action of local governments. Sister city relations are among the international collaborations of local governments representing cities, regions and states. Managers of Washington-Hyogo, California-Osaka and Hawaii-Hiroshima sister cities in the USA and Japan and managers various regional non-governmental organizations made some recommendations at the end of the three-day conference process where lessons learned and best practices on planning, preparation and response to natural disasters were shared. Taking these recommendations into consideration, sister city relations were considered as a disaster management model in the context of local governments at national level. In the model, city pairings were made by taking into consideration factors such as fault line, population, cities not being close to each other, geographical location, etc. The main purpose of these pairings is to prevent managerial uncertainty and other weaknesses that may arise in the event of a possible disaster and to take action quickly. With the sister city disaster management model, it is thought that sharing the knowledge and experiences of sister cities regarding past disasters among themselves will provide significant contributions to the cities.

A Mathematical Model to Assess the Impact of Tourism Activities on the Economy of Vendors at Bukit Maras, Terengganu, Malaysia

Bukit Maras is one of the recreational spots that has been identified as having great potential to be promoted as a tourist destination in Terengganu. In this study, it is intriguing to see the whether the tourism activities that occurred at Bukit Maras have a positive impact on the economic activity of the local vendors from the point of view of mathematical modelling. The objective of this paper is to formulate a mathematical model in the form of ordinary differential equations (ODEs), inspired by the concept of symbiosis interaction in ecology. Further, some mathematical analyses of this model such as finding the steady states and their stability, were also proved. In addition, some numerical simulations are performed using Maple software to produce the plots of time series as well as phase portraits. To prove the positive impact of the presence of tourists on the economics of vendors, a parameter called the spending rate by the tourists was varied. The results showed that as the spending rate increased, it was expected that the number of vendors would increase too. This indicated that the economics of the vendors have improved. Moreover, it is also predicted that the number of tourists will continuously increase in the future, provided that the attractiveness factors of the Bukit Maras are well preserved. These results are significant for the local government to provide more funding for the development of Bukit Maras so that both tourists and vendors can be sustained in the future.

Unique Possibilities of Dynamic Metal–Polymer Interactions in Selective Hydrogenation

AbstractRationally designed polymers can function as supports or promoters for metal catalysts, imparting distinct catalytic properties in selective hydrogenation. With strongly metal–ligating functional groups, mobile polymer chains can spontaneously decorate the metal catalyst surfaces under mild conditions, forming stable metal–polymer interfaces. We have termed this phenomenon ‘dynamic metal–polymer interaction (DMPI),’ which can be roughly considered as an organic version of the strong metal–support interaction (SMSI) concept. The polymer chains that dynamically interact with the metal surface can control the adsorption of reactants and products through competitive adsorption, significantly improving selectivity and catalyst stability. One of the remarkable advantages of using polymers as catalytic materials is that their molecular structures, such as molecular weight, crystallinity, and chemical functionality, can be tailored using rich organic chemistry. This, in turn, allows us to precisely tune the metal–polymer interactions and catalytic properties. In this Concept, we will discuss how metal–polymer interfaces can be designed and utilized for selective hydrogenation, with a particular emphasis on the industrially relevant acetylene partial hydrogenation reaction.

Технологии взаимодействия государства с молодёжью в 2000–2020-е

The relevance of this article is related to the development of interaction between the state and youth in 2000–2020s and is determined by the development of patriotic state youth policy implemented in the conditions of a special military operation. Until the end of the 2010s the communication of state bodies with youth was much less active, and the interaction was more hierarchical. The author of the article examines the evolution of com-munication technologies of public authorities with young people in the 2000s and 2020s. This article is both theoretical and applied in nature. That is, the theoretical aspect consists in analyzing the concepts of interaction between the state and youth. The applied aspect consists in a brief analysis of the activities of public opinion leaders and youth social movements that disseminate pro-state information agenda.

Temporal Interactions between Maintenance of Cerebral Cortex Thickness and Physical Activity from an Individual Person Micro-Longitudinal Perspective and Implications for Precision Medicine.

Maintenance of brain structure is essential for neurocognitive health. Precision medicine has interests in understanding how maintenance of an individual person's brain, including cerebral cortical structure, interacts with lifestyle factors like physical activity. Cortical structure, including cortical thickness, has recognized relationships with physical activity, but concepts of these relationships come from group, not individual, focused findings. Whether or how group-focused concepts apply to an individual person is fundamental to precision medicine interests but remains unclear. This issue was studied in a healthy man using concurrent micro-longitudinal tracking of magnetic resonance imaging-defined cortical thickness and accelerometer-defined steps/day over six months. These data permitted detailed examination of temporal relationships between thickness maintenance and physical activity at an individual level. Regression analyses revealed graded significant and trend-level temporal interactions between preceding activity vs. subsequent thickness maintenance and between preceding thickness maintenance vs. subsequent activity. Interactions were bidirectional, delayed/prolonged over days/weeks, positive, bilateral, directionally asymmetric, and limited in strength. These novel individual-focused findings in some ways are predicted, but in other ways remain unaddressed or undetected, by group-focused work. We suggest that individual-focused concepts of temporal interactions between maintenance of cortical structure and activity can provide needed new insight for personalized tailoring of physical activity, cortical, and neurocognitive health.

Meanings and implications of love: review of the scholarship of love with a sub-Saharan focus

Love, as an emotion, binds people together in social practices that are contingent on culture, historical processes, and social trends. As such, love is a perfect site to study how people interact and to understand how power, equality, and sustainability play out in human relations. Despite its importance and much attention, love as a concept and form of interaction is not fully understood, especially not across cultures. In our research, mainly in sub-Saharan Africa, we show that alongside other emotions, love matters not only for passion in life or for wellbeing but also for improved resource use, increased gender equality, and, subsequently, higher food security and sovereignty – all signs of sustainability. While love is understood as a universal human phenomenon, definitions and expressions of love vary across time and cultures. Since love drives human interaction in many intertwined ways there is no single best way to define it. Yet, scholars have advanced the theory of love by identifying at least 40 major distinct but interdependent ‘love constructs’ fitting into the four main dimensions of affection, closeness, compassion, and commitment (Karandashev et al. 2022). In parallel to this and based on our review of the scholarship of love in a subset of 45 relevant academic articles from an 80-article systematic literature search of ‘love’ we find four core (and partly overlapping) types of how to speak about love as an expression and experience. These include: 1/ contextual love influenced by culture, space, and time; 2/ romantic and compassionate love; 3/ transactional love; 4/ post-humanist perspectives and ‘harmony love’. Finally, we examine love in relation to power; love-related emotions; and how understandings of love and culture impact gender relations.

Weak determinism and the computational consequences of interaction

Recent work has claimed that (non-tonal) phonological patterns are subregular (Heinz 2011a,b, 2018; Heinz and Idsardi 2013), occupying a delimited proper subregion of the regular functions—the weakly deterministic (WD) functions (Heinz and Lai 2013; Jardine 2016). Whether or not it is correct (McCollum et al. 2020a), this claim can only be properly assessed given a complete and accurate definition of WD functions. We propose such a definition in this article, patching unintended holes in Heinz and Lai’s (2013) original definition that we argue have led to the incorrect classification of some phonological patterns as WD. We start from the observation that WD patterns share a property that we call unbounded semiambience, modeled after the analogous observation by Jardine (2016) about non-deterministic (ND) patterns and their unbounded circumambience. Both ND and WD functions can be broken down into compositions of deterministic (subsequential) functions (Elgot and Mezei 1965; Heinz and Lai 2013) that read an input string from opposite directions; we show that WD functions are those for which these deterministic composands do not interact in a way that is familiar from the theoretical phonology literature. To underscore how this concept of interaction neatly separates the WD class of functions from the strictly more expressive ND class, we provide analyses of the vowel harmony patterns of two Eastern Nilotic languages, Maasai and Turkana, using bimachines, an automaton type that represents unbounded bidirectional dependencies explicitly. These analyses make clear that there is interaction between deterministic composands when (and only when) the output of a given input element of a string is simultaneously dependent on information from both the left and the right: ND functions are those that involve interaction, while WD functions are those that do not.

ESG: Transformation of interpretations

Purpose: to identify directions of transformation in the ESG interpretations in the system of interrelated scientific conceptions. Methodology: the study is based on the interpretation of the abbreviation ESG as a term element that forms ESG issues acting as specific ESG factors. The consideration of these factors meaningfully transforms the conceptions that explain the interaction between business, society and nature. Findings: acknowledging ESG factors fills new meanings in the content of the following conceptions: responsible investment, risk management and business responsibility in general. Also, it stimulates the reinterpretation of the “umbrella” conception of interaction between business, society and nature including the conception which exists in the form of ideological preference. Originality and contribution: the work identifies the directions and presents an original model for transforming the interpretations of ESG in the relevant interrelated scientific conceptions that explain the interaction between business, society and nature. The incorrectness of using the term “ESG conception” in scientific research is substantiated.

The Interaction between Dramatic Writing and the Construction of National Identity in the Southern National Society Period

Abstract Starting from the background of the development of Chinese and Western cultures, this paper analyzes the textual themes and interprets the ideas of the dramas created during the period of the Nanguosha. Taking into account the specificity of the era and the national perception of Nanguosha’s theatrical works, the concept of theatrical cultural interaction is put forward to analyze the basis of cultural interaction in the cultural acceptance behavior of drama. Audience interaction behavior and audience emotional intelligence are chosen as intermediary and moderating variables respectively, and a four-variable research model is constructed for the creation of Nanguosha’s dramas, the construction of national identity, audience interaction behavior and audience emotional intelligence. Introduce the causal mediation effect model based on Nanguosha theater culture, explain the symbolic variables, and discuss the estimation method for the causal mediation effect. Combine the empirical data with the descriptive analysis and correlation analysis of the variables, and carry out the main effect test, mediation effect test, moderating effect test, and moderated mediation effect test of the research hypotheses in order to verify the interaction of the variables. After introducing the mediator variable of audience interaction behavior, the regression coefficient of Nanguosha’s drama creation on national identity construction is β =0.198, P<0.01, which confirms that there is a relationship of positive influence of Nanguosha’s drama creation on national identity construction, and that the audience interaction behavior plays a partly mediating role in the process of Nanguosha’s drama creation’s role in national identity construction.

Blockchain-based key-value store to support dynamic smart contract interaction in the agricultural sector

<span>In the era of supply chain digitalization, adaptability and transparency are key to enhancing efficiency and trust. Although blockchain technology and smart contract offer innovative solutions, the limitations of static smart contract hinder their full potential. This article introduces a new approach using dynamic smart contract capable of managing various commodities in the supply chain with a key-value store. While this advantage provides flexibility, it still poses challenges in managing increasingly complex interactions among various actors, especially when the number of commodities increases. To address these challenges, this study introduces the concept of smart contract interaction that facilitates the automation and management of interactions with high efficiency. The implementation results show that smart contract interaction outperforms conventional approaches in terms of speed, resilience, and ease of management. Through the combination of dynamic smart contract and smart contract interaction, demonstrating how efficiency, transparency, adaptability, and scalability can be achieved in the supply chain, providing new insights into the utilization of blockchain technology for the modern industry.</span>
