abstract = {Recent research has pointed out the importance of appearance similarity as a special instance of homophily. The current paper introduces body mass index (BMI) similarity as a convenient and powerful proxy of perceived appearance homophily in the context of female advertising models by showing process evidence and boundary conditions for the effect of BMI similarity on marketing-relevant downstream variables. Study 1 tests how BMI similarity relates to a traditional measure of appearance homophily and perceived reliability of a female advertising model. Study 2 shows that BMI similarity influences perceived product quality and purchase intention. Website vividness negatively moderates the relationship between BMI similarity and product quality. Study 3 tests for alternative explanations and provides support for the mediating effect of appearance homophily for the relationship between BMI similarity and perceived product quality. The findings provide marketing managers with important insights on how to increase their marketing effectiveness by integrating BMI similarity into their marketing communications. Additionally, using BMI similarity serves as an alternative way to promote diversity and inclusion of models with plus-size body type often sought by societal brands.},

If investors hold disproportionately high carbon emitters with the associated increased carbon risk stocks, the stock market reacts less positively (more negatively) to dividend increase (decrease) announcements.

abstract = {This paper explores the convergence of development economics, regulatory policies, and public health considerations within the field of Information Systems (IS) research, focusing specifically on 5G and 6G mobile technologies. Despite the widespread deployment of these technologies and their potential health implications, there is a limited understanding in IS literature on why countries adopt varying thresholds for radiation regulation. Our study, analyzing data from 124 countries, uncovered an inverted U-shaped relationship between digital literacy and the rigidity of radiation regulation. This finding reveals that nations with lower digital literacy levels tend to enforce stricter regulations, whereas those with higher literacy levels adopt more relaxed policies. By highlighting how digital literacy, a critical aspect of the digital divide, significantly influences regulatory frameworks in telecommunications, this study contributes to filling the gap in IS research. This under- scores the necessity of informed and transparent regulatory decision making, especially in countries with diverse levels of digital literacy. Calling for a multidisciplinary approach to policy formulation, our work enriches the broader discourse in IS research, underlining the pivotal role of digital literacy in shaping both the access and regulatory landscapes of emerging technologies.},

abstract = {The rapid growth of industrial digitalization in the Industry 4.0 era is fundamentally transforming the industrial
sector by connecting products, machines, and people, offering real-time digital models to allow self-diagnosis,
self-optimization and self-configuration. However, this uptake in such a digital transformation faces numerous
obstacles. For example, the lack of real-time data feeds to perform custom closed-loop control and realize
common, powerful industrial systems, the complexity of traditional tools and their inability in finding effective
solutions to industry problems, lack of capabilities to experiment rapidly on innovative ideas, and the absence
of continuous real-time interactions between physical objects and their simulation representations along with
reliable two-way communications, are key barriers towards the adoption of such a digital transformation.
Digital twins hold the promise of improving maintainability and deployability, enabling flexibility, auditability,
and responsiveness to changing conditions, allowing continuous learning, monitoring and actuation, and
allowing easy integration of new technologies in order to deploy open, scalable and reliable Industrial Internet
of Things (IIoT).
A critical understanding of this emerging paradigm is necessary to address the multiple dimensions of
challenges in realizing digital twins at scale and create new means to generate knowledge in the industrial
IoT. To address these requirements, this paper surveys existing digital twin along software technologies,
standardization efforts and the wide range of recent and state-of-the-art digital twin-based projects; presents
diverse use cases that can benefit from this emerging technology; followed by an in-depth discussion of the
major challenges in this area drawing upon the research status and key trends in Digital Twins.},

This setting allows the modeling of more realistic real-life scenarios in which agents not only will leave the domain at a certain point in time (like during the evacuation of pedestrians or in debt refinancing dynamics) but also act competitively to anticipate the strategies of the other agents. We shall establish the existence of Nash Equilibria for such class of mean-field game of controls systems under certain regularity assumptions on the dynamics and the Lagrangian cost. Much of the paper is devoted to establishing several a priori estimates which are needed to circumvent the fact that the mass is not conserved (as we are in a Dirichlet boundary condition setting). In the conclusive sections, we provide examples of systems falling into our framework as well as numerical implementations.},

abstract = {The irregularity of the time interval between observations in and across the stream is a key factor that leads to a drop in performance when classical machine learning or deep learning models are used for a downstream task requiring multivariate time series. Indeed, irregular multivariate time series not only increase the rate of missing values but also lead to data sparsity, which consequently makes the data almost unleverageable and/or ineffective for models. To tackle this scorching challenge, most of the pioneering approaches apply imputation or interpolation in their core, which might lead to embedding data with noise. To especially address this irregular multivariate time series issue, we introduce, in this paper, a new deep neural network model called ALignment-driven Neural Network. The innovative idea of our model is to transform the irregular multivariate time series into pseudo-aligned (or pseudo-regular) latent values. The latter are shown as a matrix, where the coefficients are the latent values of each feature at user-defined reference time points that are evenly spaced. They are obtained through a duplication process driven by an exponential decay mechanism. The obtained output is then passed to a Recurrent Neural Network model, which is undoubtedly the must-use model for regular time series data. To show that our model added value, we looked at the Intensive Care Unit mortality prediction task. In this unit, the physiological measurements used to make decisions have a problem with time irregularity. Leveraging the publicly available MIMIC-III, we compare the performance of our model to that of flagship models. In addition, we also performed extensive ablation studies to highlight the importance of specific components in our model. Interestingly enough, whenever data is collected 24 and 48 h after a patient's admission, we outperform our pioneering competitors, i.e., +1.1% and +1.5% for the AUC score, +2.3% and for the AUPRC score and +0.6% and +1.7%
for the F1-score.},

abstract = {The sociomaterial lens within IS research holds that agency should not be considered as a property
solely of humans, or of technology, but instead arises from an emergent interaction between
the two. This, emergent, account of agency deepens our understanding of unfolding IS practice,
but its largely cognitive orientation remains naïve towards affectively-sensed motivations that
also form part of this interaction. By implication, a sociomaterial perspective lacking an affective
dimension offers an incomplete conceptualisation of information systems. In response, an
affectively-informed negative ontology encourages IS researchers to extend their focus beyond the
visible, to encompass how actors' receptiveness towards material objects (discourses, technologies)
is shaped by deep, affectively-derived motivations of which they are not focally aware, but
which nonetheless acquire agency in contributing to a sociomaterial outcome. A central argument,
and illustrative empirical vignette, illustrate how the concepts of sociomateriality, affect,
and negative ontology combine to offer researchers an enhanced understanding of relational
agency. A discussion follows, exploring some initial ontological, epistemological and methodological
implications of an affectively-informed negative ontology for IS research.},

In the latter model, we show that a Hurst exponent close to 1/2 can lead to a very high informativeness of the time series, because of the stationarity mechanism extcolor{red}{induced by the Lamperti transform. This result contrasts with the zero information of the fractional Brownian motion for the same value of the Hurst exponent.} In addition, we introduce a multiscale method to get a deeper interpretation of the entropy and of the market information, depending on the size of the information set. Applications to Bitcoin, CAC 40 index, Nikkei 225 index, and EUR/USD FX rate, using daily or intraday data, illustrate the methodological content.},

We considered the overall satisfaction of employees as a moderator and empirically tested the relationships. The theoretical model was conceptualised by keeping the dynamic capability view in mind. The samples for the online survey were selected from food supply chain (FSC) firms. Hypothesis testing was performed and findings indicate that lower-order capabilities, such as adaptability, agility, and alignment capabilities, play a critical role in developing dynamic capability, that is, digital technology capability, which helps in achieving superior operational performance. However, innovative lean management capability plays a partial mediation role between digital technology capability and operational performance. A moderating role for continuous learning and overall satisfaction of employees was also supported. FSC firms should consider these factors to enhance operational performance in a dynamic business environment.},

abstract = {The Qinghai?Tibet Plateau (QTP) is highly susceptible to destructive rainstorm hazards and
related natural disasters. However, the lack of sub?daily precipitation observations in this region has hindered
our understanding of rainstorm?related hazards and their societal impacts. To address this data gap, a new
approach is devised to estimate sub?daily precipitation in QTP using daily precipitation data and geographical
information. The approach involves establishing a statistical relationship between daily and sub?daily
precipitation based on data from 102 observation sites. This process results in a set of functions with six
associated parameters. These parameters are then modeled using local geographical and climatic information
through a machine learning algorithm called support vector regression. The results indicated that the temporal
scaling characteristics of sub?daily precipitation can be accurately described using a logarithmic function. The
uncertainty of the estimates is quantified using the coefficient of variance and coefficient of skewness, which are
estimated using a logarithmic and linear curve, respectively. Additionally, the six parameters are found to be
closely linked to geographical conditions, enabling the creation of a 1?km parameters data set. This data set can
be utilized to quantitatively describe the probabilistic distribution and extract key information about maximum
precipitation duration (from 1 to 12 hr). Overall, the findings suggest that the generated parameters data set
holds significant potential for various applications, including risk analysis, forecasting, and early warning for
rainstorm?related natural disasters in QTP. The innovative method developed in this study proves to be an
effective approach for estimating sub?daily precipitation and assessing its uncertainty in ungauged regions},

abstract = {In a changing business environment, firms encounter significant challenges to fulfill sustainable development goals. However, firms can make substantial progress by adopting regenerative approaches grounded in circular economy principles, enabling them to effectively pursue sustainable development objectives such as responsible production and consumption (goal 12), climate action (goal 13), and the preservation of life on land (goal 15). However, there is a scarcity of research studies that offer guidance to top supply chain (SC) executives, aiming to enhance their environmental focus and enhance the SC viability through regenerative SC practices. This study employed the philosophical perspective of the natural resource-based view. Advancing the SC literature, it tested a theoretical model to investigate the relationship between the political skills and SC analytics skills of top SC executives and the environmental orientation of SCs. Additionally, it examined the direct and indirect (via regenerative SC) relationships between a firm's environmental orientation and SC viability. This study also tested the moderating role of a firm's artificial intelligence-driven big data analytics culture in these relationships. Applying a mixed-methods approach, the study derived a theoretical model to link the aforementioned constructs. Apart from a qualitative investigation, data were also collected through a questionnaire-based survey from 375 samples. The results indicated that the relationship between the political skills and SC analytics skills of top SC executives toward the environmental orientation of SCs is significant. Furthermore, they indicated that a firm's environmental orientation is positively related to a regenerative SC, which in turn enhances SC viability. The findings also provided evidence that a firm's AI-driven big data analytics culture enhances the strength of these relationships. The current study extends the knowledge base by integrating the two unique concepts of digitalization and circular economy.},

abstract = {Rapid industrialization and global supply chains have magnified industrial activities' carbon footprint, resulting in environmental hazards. Several countries have magnified their efforts to reach carbon neutrality goals. The increased attention to carbon-neutral goals has been enabled by United Nations (UN) calls for a carbon-neutral economy. In this context, supply chains will have greater responsibilities to reduce the network's carbon footprint. To achieve carbon neutrality goals, decision-makers must be well-informed and facilitated with suitable theoretical frameworks. In literature, the adoption of intelligent technologies is suggested to construct efficient and smart supply chains. However, there are uncertainties regarding the impact of this transformation on the carbon neutrality goal. The present study caters to the uncertainties by discussing its potential impact on carbon neutrality goals and how to use adopted technologies to achieve the same. A list of 11 potential strategies is identified and modelled to provide a strategic roadmap for smart supply chains' adoption. The proposed framework aims to facilitate carbon neutrality goals. The findings indicate that decision-makers must pay significant attention to circular economy practices. Additionally, green transportation is an impactful area with significant potential to support carbon neutrality goals. Critical insights have been extracted regarding stakeholders' training and process innovation. The study findings can help decision-makers achieve carbon neutrality goals.},

Furthermore, five research hypotheses are tested using samples from food manufacturers and other related supply chain partners. Covariance-based structural equation modelling technique is used in this study, and necessary tests were done to ensure the high quality of findings. Buyer-supplier partnerships demonstrate both direct and indirect effects on the CE performance in FSC. The findings supported the serial mediation effect wherein buyer-supplier partnerships are found to exert their impact on the CE in FSC through commitment contracts and innovation performance in a successive way. The uniqueness of this study lies in the use of behavioural economics concepts to enhance CE performance.

abstract = {Although the circular economy is commonly used among industries in developing countries to achieve carbon neutrality targets, its impact on social sustainability must be clarified. Stakeholders (for instance, community stakeholders) have been observed to be unaware of the focal firm's circular supply chain activities. Because this gap has not been generally reflected in the literature, it is critical to perform an empirical study to bridge the gap between theory and practice. The goal of this research was to determine whether new technologies such as big data and predictive analytics might influence an organization's propensity to share information related to circular economy practices with stakeholders as well as to increase connectivity with those stakeholders in the Industry 4.0 era. We also investigated whether these actions could increase stakeholder trust and engagement and social sustainability as a result. We tested our theoretical model using samples from food supply chain firms in South Africa. Confirmatory factor analysis was conducted using WarpPLS 7.0 software. The findings show that firms that deploy big data and predictive analytics are more likely to share information related to the circular economy with stakeholders and that these firms are also well-connected with those stakeholders, resulting in increased trust and engagement. This, in turn, contributes to the social sustainability of supply chains. Our research has made a significant contribution by encouraging a theoretical debate regarding the willingness to share information regarding the circular economy and the social sustainability of the supply chain.},

The method belongs to a class of viscosity-splitting procedures and it consists of separating the convection term and incompressibility constraint into two time steps. Unlike the conventional projection methods, the viscosity is not dropped in the last step allowing to enforce the full original boundary conditions on the end-of-step velocity which eliminates any concerns about the numerical boundary layers. We carry out a rigorous error analysis and provide a full first-order error estimate for both the velocity and pressure solutions in the relevant norms. Numerical results are presented for two test examples of non-
Newtonian fluid flows to demonstrate the theoretical analysis and confirm the reliability of this viscosity-splitting scheme.},

resulted in a decreased immune cell infiltration into the spheroids. Moreover, the presence of cortisol deregulated the normal levels of the pro- and anti-inflammatory cytokines IFN-?
and IL-10. We present an individual-based model to explore the interaction dynamics between tumour and immune cells under psychological stress conditions. With our model,
we explore the processes underlying the emergence of different levels of immune infiltration,
with particular focus on the biological mechanisms regulated by IFN-? and IL-10. The set-up of numerical simulations is defined to mimic the scenarios considered in the experimental
study. Similarly to the experimental quantitative analysis, we compute a score that quantifies the level of immune cell infiltration into the tumour. The results of numerical simulations indicate that the motility of immune cells, their capability to infiltrate through
tumour cells, their growth rate and the interplay between these cell parameters can affect the level of immune cell infiltration in different ways. Ultimately, numerical simulations
of this model support a deeper understanding of the impact of biological stress-induced mechanisms on immune infiltration.},

Business organizations function under social norms, and to establish an ethical identity, they must show corporate ethical responsibility, embrace ethical standards, and maintain open communication with suppliers. While an organization's reputation is impacted by the absence of an ethical identity, its financial success is unaffected. Extant literature has not thrown a spotlight on social and environmental performance which indicates that less focus has been given by academics than by practitioners. To fill the lacuna in the existing literature, this study examines the relationships between corporate ethical identity, corporate brand identity, social and environmental performance. The study uses a deductive research approach and develops hypotheses which are further tested using variance based structural equation modeling. The study offers a distinctive contribution to ethics theory and stakeholder theory by showing that developing an ethical identity requires more than just adhering to moral guidelines and upholding open communication. Companies must show that they are ethically responsible towards society. The study provides evidence of the influence corporate brand identity has on environmental and social performance.

abstract = {Purpose: In this study, we provide a better understanding of the role of leader humility in employee voice by
examining simultaneously the mediating role of intention to share knowledge and the moderating role of
organizational tenure.
Design/methodology: We developed and tested a mediated moderation model. The study hypotheses were tested
with partial least squares structural equation modeling techniques.
Findings: Results from 309 medical representatives supported the study hypotheses, indicating that leader humility
is related to employee voice via intention to share knowledge, and this relationship is stronger for shortertenured
employees than for longer-tenured ones. The study also provides implications for both theory and
practice.
Practical implications: The study provides empirical evidence in support of the positive effect of leader humility on
employee voice. Therefore, we suggest that executive administration should pay particular attention to promoting
humility in leadership to appropriately manage extra-role behavior such as employee voice.
Originality: Recently, leader humility has attracted scholarly attention in organization studies. It is considered a
key antecedent of employees' extra-role behavior and a contextual factor that is associated with many positive
employee and organizational outcomes.},

This study explores both the direct impact of economic policy uncertainty and coal price on carbon prices as well as the indirect impact of economic policy uncertainty on carbon prices through coal prices by utilizing the DCC-GARCH model and the NARDL model. The findings indicate that the dynamic correlations between coal prices and the CEPU are always negative and that those between the price of carbon and the CEPU vary by area. Meanwhile, the dynamic correlations between coal and carbon prices are only positive in Shenzhen and Beijing. Both coal prices and economic policy uncertainty produce asymmetrical impacts on carbon prices. Some policy implications are provided for developing the carbon markets in light of the results drawn from the study.},

abstract = {The irregularity of the time interval between observations in and across the stream is a key factor that leads
to a drop in performance when classical machine learning or deep learning models are used for a downstream
task requiring multivariate time series. Indeed, irregular multivariate time series not only increase the rate of
missing values but also lead to data sparsity, which consequently makes the data almost unleverageable and/or
ineffective for models. To tackle this scorching challenge, most of the pioneering approaches apply imputation
or interpolation in their core, which might lead to embedding data with noise. To especially address this
irregular multivariate time series issue, we introduce, in this paper, a new deep neural network model called
ALignment-driven Neural Network. The innovative idea of our model is to transform the irregular multivariate
time series into pseudo-aligned (or pseudo-regular) latent values. The latter are shown as a matrix, where the
coefficients are the latent values of each feature at user-defined reference time points that are evenly spaced.
They are obtained through a duplication process driven by an exponential decay mechanism. The obtained
output is then passed to a Recurrent Neural Network model, which is undoubtedly the must-use model for
regular time series data. To show that our model added value, we looked at the Intensive Care Unit mortality
prediction task. In this unit, the physiological measurements used to make decisions have a problem with
time irregularity. Leveraging the publicly available MIMIC-III, we compare the performance of our model to
that of flagship models. In addition, we also performed extensive ablation studies to highlight the importance
of specific components in our model. Interestingly enough, whenever data is collected 24 and 48 h after a
patient's admission, we outperform our pioneering competitors, i.e., +1.1% and +1.5% for the AUC score, +2.3%
and +2.4% for the AUPRC score and +0.6% and +1.7% for the F1-score.},

This theory is used as a driver for a 2-year action research project conducted at a French management consulting firm during the second attempt of its Business Intelligence (BI) tool baptized ?PMT.? While most MIS methods tend to manage conflicts within the boundaries of an IT project, we emphasize the need for a comprehensive understanding of past IT implementations and their impact on subsequent projects despite the different aims, designs, and functionalities of these IT systems. This research calls for IS researchers and practitioners to adopt a holistic conflict management perspective, considering the IT portfolio and the interplay between various IT systems to ensure successful IT implementation.},

This study involved the synthesis of 33 published articles and a total of 3421 social media documents, including tweets, posts, expert opinions, and industry reports on utilizing LLMs in supply chain management. By employing BERT models, four core themes were derived: Supply chain optimization, supply chain risk and security management, supply chain knowledge management, and automated contract intelligence, which provides the present status of LLM in the supply chain. The results of this study will empower managers to identify prospective applications and areas for improvement, affording them a comprehensive understanding of the antecedents, decisions, and outcomes detailed in the framework. The insights garnered from this study are highly valuable to both researchers and managers, equipping them to harness the latest advancements in LLM technology and its role within supply chain management.},

The theoretical framework is integrated with the institutional theory and the resource-based view (RBV). The empirical method is used for collecting data through surveys and further covariance-based structural equation modeling is used to test the hypotheses. Findings indicate that carbon-neutral-based government policies have a stronger influence on tangible resources and human skills than intangible resources related to Industry 4.0 driven smart manufacturing. Second, carbon-neutral policy alignment with the firm's sustainability objectives plays a moderating effect on the relationship between carbon-neutral-based government policies and resources (tangible, intangible resources and human skills) for Industry 4.0 driven smart manufacturing. Lastly, the three resources (tangible, intangible resources and human skills) for Industry 4.0 driven smart manufacturing play a critical role in developing firms' carbon-neutral capability and further enhancing operational performance. Managerial implications include investment in advanced digital technologies, developing a strong mindset among employees and supply chain stakeholders, and designing training programs for enhancing smart manufacturing performance to develop carbon-neutrality capability. This study proposes a hybrid theory in the context of carbon neutrality by integrating institutional theory and RBV. This is the first study that examines the effect of carbon neutrality-based government policies on vital Industry 4.0-driven smart manufacturing resources and the indirect effect on carbon neutrality capability and operational performance.},

abstract = {Purpose
?Born global firms? are those organizations which, from their inception and by nature, adopt an essentially global-scale entrepreneurial functional and attitudinal strategy for growth. They seek to gain significant competitive advantage by utilizing their internal resources while leveraging external environment potentialities, to sell their outputs internationally. The aim of this research is to investigate the influence of the external business environment and the dynamic capabilities of born global firms, on their strategic and operational performance, as well as the role of leadership vision on their internationalization performance.
Design/methodology/approach
Initially and resting on extant literature with pertinent foci, including the absorptive capacity and the dynamic capability view theories, a conceptual model is proposed. Subsequently, the model is validated through the partial least square structural equation modeling technique, based on 417 respondents from Indian firms.
Findings
The study concludes that the external business environment and internal dynamic capabilities of born global firms have a significant and positive impact on their strategic, as well as operational performance; with leadership vision playing a significant moderating role to this relationship. The study finally presents the executive implications of the findings and identifies the avenues for further scientific research.
Originality/value
This is a unique study on the topic, both in relation to resources/capabilities versus performance and with regards to the leadership vision's role. It moreover focuses on a primary business force, India, which comprises prime examples of global entrepreneurship. The research constituting a significant contribution to knowledge, as research on how small firms can strategically grow so rapidly and effectively, is still far from conclusive, particularly under the present evolutions that incessantly redefine the contextual business forces upon which strategy is drawn.},

It is an upcoming field of research and not many studies are available to understand the consequences of Industry 5.0 in the context of ambidexterity and absorptive capacity of the organization, especially from supply chain flow perspective in post COVID-19 period. Also, not many studies are available which have investigated the role of senior leadership support to facilitate adoption of industry 5.0 and sustainability of supply chain management process in the post COVID-19 period. With the support of absorptive capacity theory and existing literature, a conceptual model has been developed which was later validated using PLS-SEM technique considering 378 respondents from different industries. The study found that there is a significant impact of absorptive capacity of the organization towards successfully using industry 5.0 related technologies which in turn positively and significantly influence sustenance of supply chain flow in post COVID-19 period. The study also found that senior leadership support is necessary to successfully adopt and use industry 5.0 for sustaining supply chain flow in the post COVID-19 period.},

note = {The practice of planting vegetation at rooftops is ancient, but in the recent years it has gained a momentum in the context of rapid urbanization. At the same time, radiations from the mobile industry are most acute in rooftops in dense urban areas, where 5G is expected to be the highest in a context of incertitude on the health effects of this technology. There are regulations to limit the exposure of people to these radiations. However, there are no regulations to protect plants and animals even though there is scientific evidence that they are also affected by this radiation.
The exposure of green roofs to high telecom radiation prevalent in large cities remains unexplored. Green roofs can be considered as an opportunity to favour connectivity in large cities. They can protect people from radiation and hence favour network deployment while offering environmental benefits. Green roofs can be also considered as a challenge since plants are highly impacted by this radiation. Ultimately, it is key to grasp the point of view of the population on whether green roofs are an opportunity or a challenge for the deployment of technology.
This article provides evidence that people are willing to fund research on the effects of mobile radiation on green roofs because of the health benefits they may directly obtain, but also because of benefits that are linked to the wellbeing of plants. Mobile users are willing to pay between 70 to 96 euros per year for research on human health, and between 32 to 41 euros per year for research on plants health. While the population's cognitive perceptions apply both to exposed people and plants, affective and moral perceptions are only relevant in our sample when there are exposed plants. The affective reactions that people have towards nature are considered among the most important predictors of environmental risk perceptions and a key element to leverage action.},

UGC analysis reflects topics related to the NFT initiatives of luxury brands, including their collaborations with artists and celebrities, which are often influenced by the Asian cultures. The perceived value of NFTs in the luxury watch category appears to be primarily functional and utilitarian. In contrast, NFTs in the metaverse cloud and the fashion category are associated with more hedonic, experiential, and symbolic value. Through analyzing transactions on OpenSea, the study also provides evidence that NFTs in the luxury fashion sector are not predominantly viewed as speculative investments.},

This research focuses on efficiently managing the vast amounts of data generated by IoT devices and the continuous data streams they produce, employing an advanced replication and placement strategy for application components across distributed Fog Computing nodes. This approach enables scalable and parallel data processing to adapt to demand fluctuations, prevent over-provisioning, and maintain low response times, making it particularly effective for the dynamic nature of data stream processing in IoT applications.
In this paper, we propose an Optimal IoT Service Replication and Placement (SRP) model, formulated as a constraint satisfaction problem, that considers the diverse requirements of IoT applications and the available infrastructure resources. Our model is designed to be adaptive and extensible, addressing the challenge of workload variability through real-time optimization.
Numerical evaluations confirm the superior performance and scalability of our model over existing methods, while maintaining quality of service constraints. This highlights the potential of our approach to improve efficiency and resource management in Fog Computing environments.},
