Factors influencing medication management during emergency department-to-home transitions: a qualitative study using the theoretical domains framework

Abstract Introduction The transition from Emergency department (ED) to home represents a high-risk period in the continuum of patient care, increasing the risk of medication errors, adverse drug events, and poor adherence. This study explored the perspectives of key stakeholder g...

Density functional theory investigation of CsMnBrxI3-x (x = 0-3) halide perovskites for optoelectronic applications

As technology and industrialization quickly advance, global energy demand increases immensely, burdening energy systems to keep up. Renewable energy is a sustainable method to remedy the demand, in particular using solar energy, which is incredibly abundant and its implementation...

Generative AI in Global Marketing for Sustainability: A Systematic Review of Creativity, Cultural Adaptation, and Governance

Generative AI (GenAI) has emerged in global marketing amid intensifying sustainability regulation and scrutiny. Yet the same generative capabilities that can support the detection of greenwashing may also facilitate its production and dissemination. This systematic review examine...

First records of benthic resting behaviour in the Pacific eagle ray Aetobatus laticeps from the eastern Pacific Ocean

Species can still surprise us with behaviours not previously documented. The Pacific eagle ray (Aetobatus laticeps) had not been seen exhibiting resting behaviour before, but recently, recreational divers in Costa Rica and Mexico documented three individuals remaining stationary...

Development and preliminary methodological evaluation of a micronutrient food exchange framework for Qatari composite dishes

BackgroundMicronutrient inadequacy remains a public health concern, highlighting the need for practical dietary tools that support adequate intake of key nutrients such as calcium, iron, and potassium.AimThis study aimed to develop and preliminarily evaluate a culturally tailored...

Performance of activated sludge and sequencing batch membrane bioreactor processes for the treatment of crab-processing saline wastewater

ABSTRACT Alt text: Graphical abstract illustrating biological treatment of crab-processing wastewater in an SMBR system, from the generation of untreated wastewater to the production of treated effluent, and its final discharge into the marine environment. Crab-processing saline...

Electrospun PVDF / BaTiO 3 ‐ TiO 2 Nanocomposite Yarns for Piezoelectric Energy Harvesting

ABSTRACT In this study, we assess the piezoelectric performance of poly(vinylidene fluoride) (PVDF) nanocomposite fibers incorporating a hybrid Barium titanate‐Titanium dioxide (BTO‐TiO 2 ) filler. The 1 wt% PVDF/BTO‐TiO 2 electrospun fiber mat yields a maximum peak‐to‐peak outpu...

Voices of Change: Low‐Skilled Migrant Workers' Perspectives on Labour Law Reforms in Qatar

ABSTRACT In the years preceding the 2022 FIFA World Cup, Qatar introduced a series of labour reforms aimed at strengthening migrant workers' rights, including the abolition of exit permit requirements, the removal of the No Objection Certificate requirement for job changes and th...

Infectious Complications in Adults Receiving Extracorporeal Membrane Oxygenation: A Systematic Review and Meta-Analysis of Nosocomial and Bloodstream Infection, Prevalence, Risk Factors, and Clinical Outcomes

Background/Objectives: Reported infection rates during extracorporeal membrane oxygenation (ECMO) vary widely, partly because case definitions are applied inconsistently. We synthesized the prevalence and prognostic association of nosocomial and bloodstream infection (BSI) acquir...

Delivery of cardiac rehabilitation through hybrid models and alternative settings by country income classification and decade: Comparisons from the International Council of Cardiovascular Prevention and Rehabilitation’s 2025 Global Audit Update

Objective Cardiac rehabilitation (CR) is an outpatient model of secondary prevention that improves patient outcomes, yet use remains limited. Hybrid/alternative CR addresses these challenges, but global availability, structure, and volumes have not been characterized since the pa...

A Blackbox Access to Load Forecasting Models Is All You Need to Breach Privacy

Machine learning and deep learning models play a crucial role in optimizing smart grid operations. While offering valuable utility, concerns arise regarding their exposure of sensitive information. Previous studies have focused on optimizing load forecasting models, such as Long...

The robotic PIANO: a critical narrative review of surgeon-controlled operative polyphony, human factors, and robotic training

Abstract Robotic surgery can concentrate control of several technical functions at the console, but such concentration does not itself confer clinical independence, reduce dependence on the perioperative team, or improve patient outcomes. We define surgeon-controlled operative po...

Propagation-physics-guided channel augmentation and temporal–spectral fusion for domain-robust underwater acoustic target recognition

Underwater acoustic target recognition (UATR) is essential for ocean-intelligence sensing, but deep learning-based models often suffer from performance degradation under ocean acoustic domain shift. This problem arises because ship-radiated noise recorded under different propagat...

HierTAC-Net: a robust and explainable hierarchical attention network for multi-configuration gastrointestinal endoscopic image classification

Abstract Colorectal cancer is a leading cause of cancer death worldwide, even though colonoscopy is an effective screening tool. Automated analysis of endoscopic images can help doctors find more lesions and make faster decisions, but current systems usually handle just one task,...

Engineering Carbon Cloth‐Catalyst Interfaces for Pt‐Free Hydrogen Evolution Across the Full pH Spectrum

ABSTRACT The development of Pt‐free electrocatalysts is critical for reducing the cost of hydrogen production through the hydrogen evolution reaction (HER). Although extensive efforts have focused on improving the intrinsic activity of earth‐abundant catalysts, the role of the ca...

How learning environments shape science achievement: evidence from PISA 2022

Purpose This study examines how students' perceptions of the school learning environment are associated with science achievement in Australia using PISA 2022 data. It focuses on five psychosocial dimensions drawn from the student questionnaire: sense of belonging, cooperation, tr...

Decentralized Solar-Driven Plant Factories Secure an Adequate Global Vegetable Supply beyond the Electricity Grid and Water Limitations

Abstract Conventional open-field vegetable production is increasingly constrained by climate volatility and natural resource endowments, creating supply instabilities and shortages that threaten global food resilience and human health. Here, we integrate solar photovoltaics and a...

Arid grown coriander essential oil and linalool: effects of microencapsulation on the control of Staphylococcus aureus in minced sheep meat

Natural preservation strategies using essential oils are gaining momentum, but their volatility and reactivity limit their application in complex food systems where pathogenic bacteria like Staphylococcus aureus remain a persistent challenge. This study addresses this gap by firs...

Zero-touch technique: a new paradigm in penile prosthesis surgery enabled by a sterile genital barrier system

Abstract Penile prosthesis (PP) implantation remains the most definitive treatment for medication-refractory erectile dysfunction (ED). Despite reductions in infection rates achieved through improved PP coatings, antimicrobial protocols, and refined surgical techniques, PP infect...

Thermo-mechanical performance of a TiAlN-coated micro-drill: effect of cutting speed and point angle on tool wear, cutting forces, and surface integrity

Abstract Cobalt Chromium Molybdenum (CoCrMo) alloys are essential for biomedical applications. However, their high hardness and low thermal conductivity severely hinder machinability. In micro-drilling, a geometric trade-off typically exists, where smaller point angles improve pe...
