Current dynamics, drivers, and vertical thermal structure around Sir Bu Nair Island (Arabian/Persian Gulf)

Abstract. Sir Bu Nair Island (SBN) in the central Arabian Gulf is one of the last locations in the UAE’s Gulf waters to retain extensive and well developed coral reefs, whereas many nearshore environments have experienced severe degradation following recurrent marine heatwaves. A...

The Euler Equations with Variable Coefficients

Abstract. We establish local-in-time existence for the Euler equations on a bounded domain with space-time dependent variable coefficients, given initial data [Formula: see text] under the optimal regularity condition [Formula: see text]. In the case [Formula: see text], we furth...

Recent Advances in V2X-Enabled Intelligent Transportation Systems: A PRISMA-Based Survey

Vehicle-to-Everything (V2X) technologies have become a key enabling technology in modern Intelligent Transportation Systems (ITS), supporting cooperative awareness, real-time data exchange, and coordinated decision-making among vehicles, infrastructure, and vulnerable road users....

Maximum Induced Matching: Recursive Computation and an Availability-Uniform Branch-Length Analysis

Induced matchings are a fundamental graph-theoretic concept with applications in secure communication, network flow, and very-large-scale integration. An induced matching in a graph is a set of pairwise non-adjacent edges such that no edge of the graph joins the endpoints of two...

Some minimum principles for a class of nonlinear elliptic problems in divergence form

In this paper we study a general class of nonlinear elliptic problems in divergence form. First, for a natural subclass of coefficients, we prove that a suitable transformation of the solution is strictly concave when the given domain is strictly convex. Then, making use of this...

The effect of Sustainability Accounting Standards Board (SASB) standards adoption on audit report lags: the moderating effect of ESG performance

Purpose This study aims to examine how voluntary disclosure of environmental, social and governance (ESG) information aligned with Sustainability Accounting Standards Board (SASB) standards affects audit report lag (ARL) and whether ESG performance moderates this relationship. De...

Hygrothermal durability of fiber anchors for externally bonded CFRP strengthening of reinforced concrete members

Externally bonded carbon fiber-reinforced polymer (EB-CFRP) sheets are now widely used for strengthening and repair of reinforced concrete structures. To mitigate debonding failure, FRP sheets are often mechanically anchored to the substrate using fiber anchors, which have gained...

Design and Optimization of Smart-Grid-Connected Microgrids for EV Charging Stations Integrating Net Energy Metering and Demand Response

The widespread adoption of EVs is expected to intensify peak demand, stress distribution networks, and increase carbon emissions if traditional grid-based charging models continue. Therefore, this study proposes a smart-grid-connected microgrid (MG) architecture for EV charging s...

Transition without transformation: net-zero industrial policy, green path diversification and creation

The development of new pathways for industrial decarbonisation is a formidable task demanding highly coordinated action. While industrial clusters are potentially key sites for low-carbon transitions, embedded regional structures if not fully understood may constrain green transf...

Urban EcoScore index-based assessment of biophilic potential and habitat-structural condition of the Kolkata metropolitan area

Urban sustainability assessment is crucial due to rapid urbanisation and environmental stress, particularly in the Kolkata Metropolitan Area (KMA), where land-use changes contribute to ecological degradation. This research develops and assesses the Urban EcoScore Index (UESI) as...

Digital twin technology and operations management efficiency in construction: the roles of information transparency, collaboration and digital readiness

Purpose This study examines how Digital Twin Technology (DTT), defined as a virtual replica of physical systems enabled by real-time data, influences operations management efficiency (OME) in the construction industry. Drawing on Resource Orchestration Theory (ROT), it explores t...

Prioritizing sustainable practices for decarbonizing construction SMEs: an actionable roadmap for capability development in developing economies

Purpose As the construction sector strives to meet global climate targets, small and medium-sized enterprises (SMEs) in developing economies represent a critical yet often overlooked frontier for decarbonization. Despite their significant role, construction SMEs face barriers suc...

A systematic review of the fabrication and mechanical properties of 3D-printed composite clay bricks

This review investigates recent developments in 3D-printed composite clay bricks, with a particular focus on material innovation, geometric refinement, and mechanical performance. A systematic review supported by bibliometric analysis of seventy peer-reviewed publications from 20...

Tail risk of Bitcoin and major cryptocurrencies: a distributional and extreme-value analysis

Abstract We study the distributional and tail-risk properties of Bitcoin and the major cryptocurrencies using daily returns from June 2014 to May 2026. For a panel of 10 assets we fit a family of heavy-tailed distributions by maximum likelihood, rank them by the Akaike and Bayesi...

The joint effects of digital transformation technologies and human lean practices on firm performance: an empirical investigation

Purpose This study examines how human lean practices (HLP), Industry 4.0 (I4.0) technologies, technical lean practices (TLP), operational performance (OP) and sustainable performance (SP) interact within the manufacturing sector of emerging economies under the constraints of a le...

A survey on secure and intelligent data transmission in fog IoT enabled smart farming environments

Fog computing is a decentralized computing paradigm that provides distributed computing capabilities closer to the edge devices. The Internet of Things (IoT) is a wireless network used for collecting and transmitting data over the internet. Fog computing and IoT together enhance...
