Green absorptive capacity and environmental sustainability: unveiling the interplay and moderating roles of blockchain and supply chain finance

Purpose Drawing on dynamic capability theory and the natural resource-based view, this study aims to examine how green absorptive capacity (GAC) enhances environmental sustainability performance (ESP) through financial performance (FP) and operational performance (OP) and how blo...

Reinforcement learning for sustainable construction scheduling: a many-objective framework with adaptive search and multi-criteria decision support

Purpose Delivering construction projects sustainably requires reconciling duration, cost, carbon emissions and the stability and utilization of site resources, yet these objectives conflict and the choice among candidate schedules is seldom made on an explicit, data-driven basis....

An ensemble machine learning approach for measuring and predicting formwork labor productivity

Abstract The construction industry is a major driver of innovation and economic growth. A key factor in this growth is the continuous focus on improving labor productivity, which directly impacts project timelines and costs. Maximizing labor productivity is crucial for overcoming...

From dental adhesives to injectable hemostats: a scoping review of antimicrobial biomaterials for oral soft-tissue bleeding

Abstract Background The management of acute oral hemorrhage in emergency settings is frequently complicated by saliva, high vascularity, and microbial presence. This scoping review maps the emerging field of multifunctional, dental-inspired biomaterials. The objective is to synth...

Environmental guilt and cultural values explain how green identity shapes sustainable skincare purchase intention among Arab Generation Z

Abstract This study explains why Generation Z consumers in Arab markets form intentions to purchase sustainable skincare products and clarifies the psychological mechanism through which green self-identities are converted into intention. Extending the Theory of Planned Behavior w...

Dual-fractional nonlocal photo-thermoelastic waves in microelongated semiconductor metamaterial interfaces with variable thermal conductivity

Purpose Unlike previous studies that investigated these mechanisms individually, the present work establishes a unified analytical formulation that elucidates their mutual interaction and reveals new coupled wave characteristics arising from the simultaneous effects of thermal me...

Enhancing free space optical CubeSat (FSOCS) communication links using low-complexity LDPC decoding techniques

In this work, a low-complexity, low-power, LDPC decoding scheme is presented to improve the performance of Free-Space Optical CubeSat (FSOCS) communication links. This hard-decision bit-flipping scheme aims to improve the performance-complexity tradeoff compared to existing LDPC...

An explainable AI framework for crack width and crack spacing prediction with serviceability-oriented design optimization of reinforced and prestressed concrete members

Abstract Reliable prediction of cracking behavior is essential for the serviceability assessment of reinforced and prestressed concrete members, where crack development depends on interacting material, geometric, reinforcement, prestressing, and loading parameters. This study pre...

Optimal design of hybrid renewable energy conversion systems using two configurations and four different algorithms for a rural village in Egypt

Abstract Decentralized energy systems can significantly enhance living circumstances in remote areas without a grid connection. This paper formulates a hybrid renewable energy model for a rural Egyptian village. The system includes PV, wind, biomass generator, battery storage, an...

Beyond the Burgers paradigm: the stabilizing role of higher-order nonlinearities in magnetized heavy ion-acoustic shocks

Abstract This paper investigates the role of higher-order nonlinearities in the propagation of heavy ion-acoustic shock waves (HIASWs) within a magnetized, collisionless plasma comprising inertial heavy ions and kappa-distributed electrons and positrons. Employing a reductive per...

INTERNAL AND EXTERNAL DETERMINANTS OF PROFITABILITY AND THE MEDIATING ROLE OF WORKING CAPITAL MANAGEMENT: EVIDENCE FROM EGYPTIAN NON-FINANCIAL COMPANIES LISTED ON THE EGX

This study examines how internal firm-specific factors and external macroeconomic conditions shape profitability among Egyptian non-financial companies listed on the Egyptian Exchange, with particular attention to the mediating role of working capital management. Drawing on secon...

Detection of stuck pipe problems during drilling tripping operations using artificial intelligence approach

Abstract Stuck pipe remains a critical challenge in the petroleum industry, often leading to significant non-productive time (NPT) and operational losses. Traditional prevention methods are frequently ineffective due to the high sensitivity to parameter changes and the presence o...

Assessing the potential, effectiveness and implementation challenges of beach and tourism ecolabels for beach macrolitter reduction

Abstract There is an urgent need to address the contribution of mass tourism to coastal litter generation, however, identifying effective, context-specific measures to reduce listed litter remains challenging. This study evaluated 142 beach and tourism ecolabels against a list of...

Can Carica papaya Serve as an Adjunct to Semaglutide in Mitigating Diabetes-Induced Testicular Injury Through Modulation of Oxidative Stress, Inflammation, Apoptosis, and the miR-34c/miR-155–SIRT1/FOXO1 Axis? An Experimental and Chem-Bio-Informatics Study

Diabetes mellitus (DM) induces significant endocrine disruption and oxidative stress (OS) within the testes, resulting in impaired spermatogenesis, increased sperm abnormalities, and compromised reproductive function. This study aimed to evaluate the combined protective effects o...
