CBT-ICU transformer: a clinician-behaviour-aware multimodal deep learning framework for early detection of critical care adverse events in MIMIC-IV

Early identification of clinical deterioration in intensive care units (ICUs) remains a major challenge despite the availability of large-scale electronic health records. Most existing models focus primarily on physiological measurements such as vital signs and laboratory results...

Deposition behaviour, optimisation, and coating quality of Al‐19Zn friction‐surfaced on low carbon steel

This study examines deposition behaviour, process optimisation, and coating geometry for aluminium–19 wt.% zinc coatings on an AISI 1020 steel substrate using friction surfacing. Nine experimental runs were attempted by varying axial pressure, rotational speed, and feed rate in o...

Ecological Quality Assessment of Mediterranean Wadis in the Bizerte Lagoon Catchment (Northern Tunisia) Using Benthic Diatoms

The study presents an integrated assessment of water quality in wadis of the Bizerte Lagoon catchment (Northern Tunisia), using benthic diatom assemblages. Seasonal sampling was conducted between winter 2023 and winter 2024 in three wadis exposed to varying anthropogenic pressure...

Integration of AI-based load forecasting and hybrid metaheuristic optimization for sustainable capacity expansion planning in decarbonized solar energy systems

With progressive integration of renewable generation and energy storage techniques, it is crucial to examine the modelling techniques and assumptions of capacity expansion planning (CEP) for power grids dominated by thermal-based systems. The proposed framework integrates artific...

Building Antimicrobial Reasoning Before Prescribing: Reframing the Role of Preclinical Microbiology Education

Antimicrobial resistance (AMR) is usually addressed through surveillance, prescribing policy, stewardship programs, infection prevention, and drug development. Less attention is given to an earlier educational question: how future doctors first learn to connect microorganisms, an...

Heat transfer and entropy analysis of shaped nanoparticles in stratified binary nanofluid flow over an exponentially curved Riga surface

The problem of controlling heat transmission and flow efficiency in advanced engineering systems, such as aerospace thermal management and next-generation cooling devices, is critically hampered by energy losses due to friction and thermal irreversibility. This study addresses th...

The Impact of Educational Interventions on Clinical Documentation Using Pretest–Posttest CRABEL Scores: A Single Group Quasi-Experimental Study among Dental Interns

Abstract Clinical documentation is essential for patient safety, legal protection, and continuity of care. Nevertheless, record-keeping skills are usually overlooked by most undergraduate dental programs. This study investigated the outcomes of a structured educational interventi...

Semiparametric hybrid air quality forecasting using prophet ensemble and feature selection

Due to air quality management and public health planning, accurately predicting PM2.5 concentrations is absolutely imperative. Having many lagged variables, interactions between pollutants and other temporal features means that high-dimensional environmental datasets (that may in...

Tailored novel nanocomposites for advanced elimination of methylene blue dye from water

Novel SrCO 3 /CuO/MgO/C (Abbreviated as CSM600) and SrCO 3 /CuO/MgO/Sr 2 CuO 2 CO 3 /Cu 2 SrO 3 /SrCuO 2 /C (Abbreviated as CSM800) multiphase nanocomposites were successfully synthesized through a Pechini sol–gel route followed by calcination at 600 and 800 °C. Structural analys...

Numerical simulation of fully developed laminar flow and heat transfer in a circular pipe

Purpose This work involves the computational analysis of two-dimensional heat transfer through convection and laminar flow of a fluid. The application was conducted on a circular pipe with fully developed laminar flow, taking into consideration boundary conditions such as the wal...

The Perceived Contribution of Online Learning Environments to Sustainable Development Goals (SDGs) in Higher Education: A Field Study Using PLS-SEM

Higher education institutions face a dual imperative: expanding access while reducing their environmental and operational footprint. Grounded in Triple Bottom Line theory and the Sustainable Development Goal (SDG) interlinkages framework, this study examines faculty and postgradu...

Phytochemical profile and in vitro antimicrobial, antiviral, and anticancer activities of Echium angustifolium ethanolic extract

Echium angustifolium is traditionally valued for its therapeutic properties; yet comprehensive studies on its biological activities are limited. Aerial flowering parts were sequentially extracted with solvents of varying polarity. Extracts were analyzed for yield, phytochemical c...

A sensitive and green spectrofluorimetric method for determination of guanfacine hydrochloride based on NBD-Cl derivatization

A sensitive and environmentally friendly spectrofluorimetric method was developed for the determination of guanfacine in pharmaceutical formulations. The method is based on derivatization of guanfacine with 4-chloro-7-nitrobenzofurazan in alkaline medium to yield a highly fluores...

Regime-Dependent Predictability of Cryptocurrency Distress: Cross-Sectional Evidence from Two Exchanges

Can the distress of a cryptocurrency be predicted from its market behavior, and is that predictability reliable when it matters most? Using daily data for 609 USD-quoted coins traded on Kraken between 2013 and 2025, we built a survivorship-inclusive coin-quarter panel and model t...

Nano-enhanced PCM-assisted solar stills: A systematic review of performance, economics, and sustainability
