The Synthesizability Gap Has Moved: Route Existence Is Not Chemistry

Abstract Synthesis-constrained generative models now guarantee that every proposed molecule carries a route to purchasable building blocks, and recent campaigns have carried such designs to synthesized, biologically active compounds. I argue that this genuine success has relocate...

Integrating physical and digital indicators in public space branding: a planning framework for hybrid urban governance

Abstract This paper examines the potential of social media as a supplementary planning resource for understanding public space branding by relating digitally mediated visibility and perception to established physical public space attributes. Despite extensive literature on digita...

Job satisfaction among Saudi and Non-Saudi critical care and emergency nurses: associations with psychological distress, turnover intention, and perceived retention strategies

Critical care and emergency nurses work in complex and demanding environments that may affect their occupational well-being, psychological health, and job satisfaction. Although previous studies have examined nurse retention challenges, limited evidence exists regarding factors a...

Integrating Sustainability, Biodiversity, and Human Health to Improve Indoor University Spaces: A Comparative Case Study Using Real-Time Environmental Monitoring and AI-Driven Analysis

Climate Change (CC) has increasingly disrupted the global environment, with significant consequences for biodiversity, cities, and human health and well-being over the past decades. Mitigating anthropogenic emissions and promoting healthier, more sustainable built environments ar...

Ensemble-based feature selection and classification for ischemic stroke subtyping

Abstract Strokes have become a major cause of death in recent years due to their effects on the central nervous system. Hemorrhagic and ischemic strokes (IS) are the two most types that severely harm the central nervous system. Subtyping ischemic stroke is crucial for both the pr...

Reliability Estimation of s‐Out‐of‐k Systems Under Inverted Z–Lindley Stress–Strength Models With Progressive Censoring: An Engineering Application

ABSTRACT Fault‐tolerant systems are built with redundancy, surviving as long as enough of their components withstand the operating load. We model an ‐out‐of‐ : G system whose nominally identical components share a common random stress and quantify its reliability when both streng...

Prevalence of Stress, Anxiety, and Depression Among Pregnant Women in Riyadh, Saudi Arabia

Background & Objective: Pregnancy is a vulnerable period for psychological distress, yet Riyadh-specific data describing stress, anxiety, and depression simultaneously and their correlates remain limited. This study was conducted with aim to estimate the prevalence of antenatal s...

Cognitive performance and dynamic spinopelvic kinematics across walking speeds in healthy young adults

Although gait is often considered highly automated, cognitive performance may be associated with dynamic trunk–pelvis kinematics as locomotor demand increases. How these associations vary across standardized walking speeds remains unclear. This study examines speed-dependent asso...

A prospective comparative study between endoscopic and microscopic myringotomy with ventilation tube insertion

Abstract Background Otitis media with effusion (OME) is a common ear disorder and a major cause of hearing loss in children. When conservative management fails, myringotomy with ventilation tube (VT) insertion remains the gold standard surgical treatment. Aim of the work to evalu...

A Spectral Tau Algorithm Using Shifted Convolved Fibonacci Polynomials for Singular Functional Models

In this paper, for some second-order singular functional differential equations (SOSFDEs), a tau-type spectral technique is built using non-origin-symmetric polynomials called shifted convolved Fibonacci polynomials as the approximation basis. Derivative formulae, integral identi...

Role of transperineal ultrasound compared to pelvic magnetic resonance imaging in assessment of vaginal abnormalities

Abstract Background Ultrasound (US), including transvaginal ultrasound (TVUS), transperineal ultrasound (TPUS), and the pelviabdominal ultrasound (PAUS) with two-dimensional (2D) and three-dimensional (3D) reformatted images, is the first-line tool in the assessment of different...

Ophthalmic manifestations of trisomy 21 syndrome in the pediatric age group: a cross-sectional study from Cairo University Specialized Pediatric Hospital

Abstract Background Trisomy 21 Syndrome is one of the most common chromosomal conditions in the world, affecting an estimated 1 in 700 live births. It manifests with a wide range of ophthalmic findings. These include strabismus, amblyopia, accommodation defects, refractive error,...

Preoperative prediction of pituitary macroadenoma consistency using diffusion-weighted MRI: A prospective study with surgical correlation

Background Preoperative knowledge of pituitary macroadenoma consistency holds considerable importance in guiding surgical strategy and optimizing patient outcomes. The mechanical properties of the tumor may determine both the feasibility of complete resection and the most appropr...

Climate Change Awareness Among Palestinians in the West Bank: A Cross-Sectional Study of Socioeconomic and Contextual Factors

Climate change awareness is increasingly recognized as a multidimensional issue related to understanding climate risks, adoption, and climate-friendly behaviors. This paper aims to explore and assess the socioeconomic contextual factors of climate change awareness in the West Ban...

Auditory P300 as a neurophysiological marker of cognitive impairment in fibromyalgia syndrome

Abstract Background Cognitive dysfunction has become a well-recognized clinical feature of fibromyalgia syndrome. Although subjective cognitive complaints are frequently reported, objective neurophysiological assessments remain limited. Auditory P300 event related potentials may...

Integrated endocrine–oxidative–metabolic and trace element responses to heat and cold stress in dromedary camels (Camelus dromedarius)

Abstract Background The dromedary camel ( Camelus dromedarius ) possesses remarkable physiological adaptations to withstand harsh desert conditions, including heat stress and drought. This study aimed to evaluate the effects of heat and cold stress on oxidative stress biomarkers,...

Prevalence of test anxiety among medical students: a systematic review and meta-analysis

Abstract Background Test anxiety is a situation-specific construct that can markedly impair cognitive functioning and academic performance in high-stakes educational environments. Medical students are frequently exposed to evaluative situations, and test anxiety is common in this...

Evaluation of the new Egyptian undergraduate medical program from students’ perspectives: a nationwide cross-sectional study

Abstract Background The global emphasis on medical education reform highlights the need for essential competencies to meet evolving healthcare demands. In Egypt, significant reforms in 2018 introduced a competency-based, integrated undergraduate medical curriculum—a five-year pro...

Phase II Monitoring of Dirichlet Profiles

ABSTRACT The quality of a product or a process is usually maintained by monitoring one or more of its quality characteristics. In some cases, these quality characteristics are highly correlated, and their sum must be equal to a constant, such data are referred to as compositional...

A model predictive control-based energy management strategy for grid-connected nanogrids

Abstract Nanogrids have emerged as a crucial solution for contemporary residential power systems, providing a robust framework for integrating distributed energy resources (DERs), comprising solar photovoltaics (PVs), wind turbines (WTs), energy storage systems (ESSs), and diesel...
