Pushing theLimits of Ultrasmall PbSe Magic-SizedClusters

Abstract Ultrasmall PbSe magic-sized clusters (MSCs) are important for probing the nucleation of nanocrystals and their optical properties under strong quantum confinement. The smallest PbSe MSC observed so far in the growth sequence has an absorption maximum at 625 nm. Here, we...

Influence of Water Molecule Adsorption and H2 ReductionTreatment on Acid Sites of WO3 with the (002)Crystal Facet Studied by Solid-State NMR Spectroscopy

Abstract In-depth investigations of the influence of water molecule adsorption and H2 reduction treatment on surface acid sites of metal oxides are vital to elucidate the mechanism of catalytic reaction and to optimize the design of catalysts. By introduction of different amounts...

LGBTQ+ healthcare preparedness among undergraduate medical students in India: a cross-sectional study of awareness, attitudes, and clinical confidence

Abstract Background Lesbian, Gay, Bisexual, Transgender, Queer (LGBTQ+) individuals in India experience significant healthcare disparities, including higher burdens of mental health conditions, HIV, and stigma, and frequently encounter discrimination in healthcare settings. Yet t...

Making learning visible in architectural internships: NLP-supported learning evidence for work-based learning support

Purpose This paper examines how natural language processing (NLP)-supported learning evidence generated from internship logs can make workplace learning in architectural internships more visible and more actionable for higher education teachers. Design/methodology/approach A qual...

Leadership development in the public sector: moving beyond competency frameworks

Purpose This study aims to examine how organizational constraints and systemic contradictions shape the enactment of leadership competencies in public sector organizations. Drawing primarily on contradiction theory and complemented by systems theory and competency-based leadershi...

Procalcitonin for diagnosing infected pancreatic necrosis: a systematic review and meta-analysis

Abstract Background Infected pancreatic necrosis (IPN) ranks among the most severe local complications of acute pancreatitis (AP) and plays a central role in driving AP-related death. Procalcitonin (PCT), a serum biomarker that responds preferentially to bacterial infection, has...

The Mathematics of Going Blank: A Carlo‑Field Model of Cognitive Collapse Under Broad Prompt Pressure

This work presents a complete Carlo‑Field subsystem modelling the cognitive blankness event that occurs when a human is asked an excessively broad question under social pressure. The document formalises the collapse of entropy, the loss of query gradient, the failure of retrieval...

The Zulfiqar Conservation Law: A 3-Edge Geometric Framework Containing Newtonian Mechanics and General Relativity as Special Cases

AbstractWe introduce the Zulfiqar Conservation Law : for any physical or mathematical systemadmitting a 3-edge blade representation, the quantity| ˜Z|2 = δ2 + D2 + ω2 = Cis conserved, where δ is the deviation edge (distance from equilibrium), D is the dual edge(directional gradie...

Engaging primary care teams with patient-reported data: design, acceptability and outcomes of a structured intervention

Abstract Background Although patient-reported data are increasingly available and their usefulness is recognized, these measures are not well integrated at the clinical levels of primary care. Also, the processes through which these data are translated into actionable insights fo...

A Systematic Review and Meta-Analysis on 30-Day Readmission Rates After Endovascular Abdominal Aortic Aneurysm Repair and Open Repair

AIM: Endovascular aneurysm repair (EVAR) and open aneurysm repair (OAR) are established treatments for abdominal aortic aneurysm (AAA). This meta-analysis evaluated 30-day readmission, patient characteristics, postoperative complications, and length of stay after EVAR and OAR, an...

Applications and Research Progress of Biomaterials for Treating Infected Bone Defects

Infected bone defects represent a challenging clinical condition that requires simultaneous infection control and bone structure reconstruction. Traditional antibiotic therapy and bone grafting each have inherent limitations. With advances in regenerative medicine and tissue engi...

Global uncertainty, gold price and macroeconomic dynamics: a comparative study of Islamic stock indices in Indonesia and Malaysia

Purpose This study aims to examine the short-run and long-run relationships between global uncertainty indicators, namely the Volatility Index, Global Economic Policy Uncertainty and Geopolitical Risk, gold prices and domestic macroeconomic variables on Islamic stock indices in I...

Combined effect of microbial and non-microbial biostimulants on wheat growth, yield, and grain nutritional quality under sandy soil conditions

Abstract Background The agricultural use of sandy soils has expanded worldwide to meet the increasing demand for food and other agricultural commodities resulting from rapid population growth and urbanization. However, the inherent limitations of these soils, particularly their l...

From "Made in China" to "Made in Türkiye" in International Trade: a Systematic Literature Review of Manufacturing Power, Technological Upgrading, and Nation Branding

The transformation of global competition from a predominantly cost-based structure towards technological capability, innovation, sustainability, and brand value has expanded the meaning of “made in” labels beyond the mere identification of a product’s country of manufacture. Thes...

Impact of Scenario-Based Teaching Centered on Gynecological Laparoscopic Surgical Procedures on Clinical Decision-Making Ability and Operative Standardization Among Resident Physicians

AIM: Scenario-based teaching has demonstrated potential in medical education, but its application to comprehensive gynecological laparoscopic training remains limited. This study aimed to evaluate the impact of scenario-based teaching centered on the complete gynecological laparo...

CMR-based aortic stiffness parameters in a symptomatic high risk obstructive sleep apnea cohort: results from the population-based Hamburg City Health Study

Abstract Background Aortic stiffness (AS) parameters as pulse wave velocity (PWV), aortic distensibility of the ascending and descending aorta (AD AoAsc, AD AoDesc) and pulse pressure (PP) are marker for vascular ageing, whereas data concerning obstructive sleep apnea (OSA) in po...

Integrated source apportionment and geochemical background assessment of organic and inorganic components in Amazonian upland lakes: insights from an extensive basin-wide geochemical database

Abstract Purpose This study established reliable natural geochemical backgrounds for Amazonian upland lakes and evaluated how lateritic catchment materials are transferred and transformed in lake sediments across Carajás, Araguaia, and Xingu. Methods Ferruginous duricrusts and la...

The Geometric Invariance Continuum (CIG): Variational Foundations and Experimental Validations

The Geometric Invariance Continuum (CIG) proposes that physical phenomena can be interpreted as manifestations of a dynamic continuum whose internal geometry possesses natural self-limiting mechanisms in extreme regimes. From a variational principle emerges a fundamental saturati...
