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...

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...

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...

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...

Clinical and Therapeutic Relevance of B7-H3 in Sarcomas: Molecular Insights from a Systematic Review

Sarcomas are a heterogeneous group of mesenchymal malignancies characterized by substantial morphological and molecular diversity. Despite advances in surgery and systemic therapies, outcomes remain poor, underscoring the need for novel biomarkers and targeted therapies. We syste...

Inkjet Printing of MXene Gas Sensors for Agricultural Monitoring

Abstract Inkjet printing enables scalable fabrication of nanomaterial-based devices, but stable droplet formation and reproducible deposition remain challenging for emerging nanosheet inks. In this work, we develop a model-guided inkjet printing framework that monitors and optimi...

Before the World Was Watching: Qatar and the 1981 FIFA World Youth Championship

Much of the existing scholarship on sport in Qatar has been shaped by the 2022 FIFA World Cup and the broader issues around it. However, many of the earlier moments in Qatar’s sporting history that were vital in shaping the country’s sporting identity have been largely overlooked...

TomoMamba: a two-stage model with state-space cross-slice propagation for breast cancer diagnosis in digital breast tomosynthesis

Abstract Digital breast tomosynthesis (DBT) provides volumetric image stacks that improve lesion conspicuity compared with two-dimensional (2D) mammography, yet most automated methods process slices independently and discard the depth-wise continuity that underpins this advantage...

Improving vehicle inspection systems: insights from users

This study examines public perceptions of a national mandatory vehicle inspection program (Fahes, Qatar). It proposes a survey-based framework for assessing user attitudes toward its safety, environmental, technical, and service-related outcomes. Using a structured online questio...

A Rare Entity in Context: Breast Implant-Associated Anaplastic Large Cell Lymphoma Compared With Common Lymphoma Subtypes

Objective: edition World Health Organization Classification of haematolymphoid tumors. Its clinicopathologic profile, treatment patterns, and outcomes, relative to those of other primary breast lymphomas, have not been characterized in large population-based comparative studies....

Zinc dimethacrylate-modified epoxy coating for corrosion protection and self-healing

Corrosion-related asset losses and safety risks are increasing the need for smarter protective coating strategies. In this work, zinc dimethacrylate (ZDMA) was incorporated into epoxy coatings for enhanced corrosion protection for carbon steel. The successful integration of ZDMA...

Kidney cancer in Eastern Mediterranean Region and Qatar: epidemiological burden patterns and etiologic risk pathways

Abstract Kidney cancer contributes substantially to the global cancer burden, with significant geographic and sex differences. Countries in the Eastern Mediterranean Region (EMR) show rising incidence and mortality alongside gaps in registry coverage and high prevalence of metabo...

Male breast cancer in Arab populations: a systematic review of molecular, genetic, and clinicopathologic characteristics

Abstract Background Male breast cancer (MBC) accounts for less than 1% of all breast cancer cases, yet its incidence is increasing worldwide. Research on MBC remains limited, particularly in Arab populations, where molecular and genetic characteristics are poorly characterized. I...

Recent advances in uranium (VI) uptake from aqueous solutions using clay mineral-based adsorbents

Due to the increasing use of nuclear energy as a primary energy source, large volumes of wastewater contaminated with radionuclides, particularly uranium, are being generated. Consequently, the quest for effective adsorbents for uranium removal from aqueous solutions has gained c...
