ESG Pillar Composition and One-Year Accounting Loss Onset: Evidence from Bloomberg-Covered Firms, 2020–2024

This study examines whether the internal composition of an environmental, social and governance (ESG) rating contains incremental information about one-year accounting-loss onset after the overall ESG level is held constant. Bloomberg environmental (E), social (S) and governance...

Novel ultra-compact 868 MHz/5GHz lowpass–bandpass diplexer for IoT

In this paper, we present a novel lowpass–bandpass diplexer designed to operate at frequencies of 868 MHz and 5 GHz. This diplexer is designed to overcome the limitations identified in previous studies. Notably, it achieves a maximum group delay of – 0.77 ns in the second passban...

Fuzzy-logic enhanced internet of things model for uncertainty-adaptive medical image segmentation

Deep learning (DL) models for brain tumour segmentation (BTS) typically produce a fixed decision boundary and do not allow the uncertainty they estimate to impact the segmentation decision (SD). This work presents a FUZIONet-Med: A Fuzzy Uncertainty-Adaptive IoT Edge Intelligence...

Post quantum federated authentication framework for Industrial Internet of Things using FALCON threshold signatures and zero knowledge verification

Abstract Distributed authentication techniques enable edge device trust in smart manufacturing and energy infrastructure Industrial Internet of Things contexts. Existing blockchain-based authentication schemes mostly use the elliptic curve digital signature algorithm, which can b...

Drivers of continuance participation intention in online retail sales events

Purpose This study aims at identifying the major drivers influencing the consumers' continuance participation intention (CPI) in online retail sales events (ORSE). It focuses on the associations of ritualistic consumption and deal proneness with shopping engagement (SE), the asso...

Strategic pathways to agility: how dynamic management control systems, strategic management accounting and knowledge management foster organizational learning and adaptability

Purpose In today’s volatile business environment, organizational agility (OAG) is critical for sustaining competitive advantage. This study aims to examine how dynamic management control systems (DMCS), strategic management accounting practices (SMAP) and knowledge management pra...

Recent advances in universal influenza vaccine platforms: paving the way for universal H5N1 vaccines and pandemic readiness

Abstract The H5N1 influenza threat is a significant issue to the overall health of the population in the world, and it demands new approaches in vaccine development and implementation. The critical path forward is the development of universal vaccine platforms, which provide long...

Multiphysics computational study of coupled analysis of thermal energy and mass transfer in a non-Newtonian fluid under chemical reaction

Thermal and solute transport enhancement is a requirement of several industrial and engineering processes like thermal and cooling systems, thermal radiators, nuclear reactor cooling, HVAC and refrigeration, etc. The rheological constitutive relations, the Stefan-Boltzmann law fo...

Beyond Screen Time: A Scoping Review of Screen Exposure and Early Childhood Development

Background: Screen exposure in early childhood has evolved beyond traditional duration-focused “screen time” to encompass a multidimensional construct including content quality, context of use, co-viewing, caregiver mediation, and developmental trajectories. Understanding these d...

Severity of activity limitation and prevalence of long COVID: a nationally representative cross-sectional study of adults in Scotland

Abstract Background Long COVID is a persistent contributor to population morbidity, and people with disabilities experience substantial and often avoidable health disadvantage worldwide. Whether long COVID is disproportionately reported among adults with current functional limita...

High-performance PVDF ultrafiltration membranes modified with ZIF-8@g-C₃N₄ nanohybrids for enhanced humic acid removal and antifouling performance

In this work, a novel metal-organic framework (MOF) hybrid, referred to as ZGCN (ZIF-8@g-C₃N₄), was incorporated into polyvinylidene fluoride (PVDF)-based ultrafiltration membranes fabricated via the phase inversion method. The ZGCN nanohybrid was synthesized through a two-step p...

Cluster headache care gaps among primary healthcare physicians in the Middle East, North Africa, and Türkiye: a multinational study

Cluster headache is one of the most severely disabling primary headache disorders and is frequently associated with diagnostic delay, inappropriate treatment, disability, and substantial psychosocial burden. Because primary healthcare (PHC) physicians are commonly the first point...

Automated and Explainable Machine Learning Framework for Predicting the Fracture Toughness of Fiber-Reinforced Ultra-High-Performance Concrete Subjected to Freeze–Thaw Damage
