Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Trust and Transformation: Institutional Complexity in Carbon Market Adoption in Emerging Economies' Land‐Based Private Sectors

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite global commitments under the Paris Agreement, empirical evidence on the involvement of the land‐based private sector of emerging economies in carbon trading remains limited. The study analyses how behavioural factors and institutional complexities influence the involvement of the land‐based private sector in carbon trading in Indonesia.

Top Management Environmental Concern, Eco‐Product Development Effectiveness and Firms' Environmental Performance: The Paradoxical Moderating Role of Environmental Information Sharing

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the combined effect of top management environmental concern and eco‐product development effectiveness on firms' environmental performance. The study also considers the moderating impact of environmental information sharing on this process.

Sustainable Innovation and Impact on Triple Bottom Line Performance: Are Innovation Types Simple Mediators?

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the way sustainable innovation, conceptualized as a second‐order construct integrating sustainable orientation and innovation culture, impacts triple bottom line (TBL) performance. It also examines the mediating roles of product, process, organizational, and marketing innovations.

Why Are Consumers Ambivalent About AI‐Generated Images? The Moderating Role of Commercial Versus Noncommercial Content Type

Journal of Consumer Behaviour, EarlyView.
ABSTRACT Grounded in ambivalence theories, this research examined factors shaping consumer ambivalence toward AI‐generated content and investigated differences between commercial and noncommercial contexts. As a preliminary study, sentiment analysis of Reddit data using a support vector machine (SVM) revealed that most consumer sentiment toward AI ...

Restricted Tweedie stochastic block models

Canadian Journal of Statistics, EarlyView.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

The Benjamin–Ono Equation in the Zero‐Dispersion Limit for Rational Initial Data: Generation of Dispersive Shock Waves

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

Comparative Assessment and Benchmarking of Metaheuristic Algorithms for Dynamic Photovoltaic Array Reconfiguration Under Diverse Shading Environments

Energy Science &Engineering, EarlyView.
ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...

DSGE Model Forecasting: Rational Expectations Versus Adaptive Learning

Journal of Forecasting, EarlyView.
ABSTRACT This paper compares within‐sample and out‐of‐sample fit of a DSGE model with rational expectations to a model with adaptive learning. The Galí, Smets, and Wouters model is the chosen laboratory using quarterly real‐time euro area data vintages, covering 2001Q1–2019Q4.

Institutional Fragility and E‐Business Adoption: A Study of SMEs in a Conflict‐Affected Economy

Strategic Change, EarlyView.
ABSTRACT This study examines e‐business adoption among SMEs in Yemen, a conflict‐affected and institutionally fragile economy. Drawing on a mixed‐methods design, it combines Partial Least Squares Structural Equation Modelling (PLS‐SEM) with qualitative interviews to analyse how war and firm size moderate the effects of key adoption drivers and barriers.
