PVC Microplastics and Cadmium Induce Premature Ovarian Insufficiency-like Changes via Glycolipid Metabolism Variation in Duck Ovary

Abstract Emerging as pervasive pollutants, microplastics (MPs) and cadmium (Cd) endanger animals’ health and safety. Currently, there is a lack of evidence about the harm mechanism of coexposure to polyvinyl chloride microplastics (PVC-MPs) and Cd in the avian female reproductive...

A Standalone Flavoprotein Monooxygenase Directs Divergent Tropolone Skeletal Editing through Baeyer–Villiger-Triggered Rearrangement

Abstract Late-stage oxidative remodeling of tropolone cores underpins the remarkable scaffold diversity in fungal meroterpenoid biosynthesis. However, the mechanistic basis by which a single enzymatic catalyst diverts a common substrate toward carbon-excising ring contraction ver...

Second mover advantage

Purpose This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comme...

What does Tafel curvature measure? A signed composition law for electrochemical kinetics

Tafel curvature is often interpreted as a direct estimate of the reorganisation energy of an electrode reaction. This preprint examines the assumptions behind that interpretation using a decomposition of forward and backward rate constants into an affinity-dependent antisymmetric...

Metabolomics-Guided Bioactivity Evaluation of Disease-Resistant Hybrid Grape Canes for Cosmetic Valorization

Abstract Grape canes constitute a valuable source of diverse polyphenols with recognized cosmetic properties, whose composition varies according to genotype and environmental conditions. Because grapevine resistance to pathogens is partly mediated by the biosynthesis of polypheno...

A Qualitative Study on Food Waste Management in Food and Beverage Businesses: The Case of Beykoz District

Sustainability and food waste management have become central to the global agenda in response to the rapid depletion of natural resources and escalating environmental challenges. The food and beverage sector, in particular, constitutes a critical component of these discussions du...

Beyond Short Names: Emoji Keyword Retrieval across Models and Bounded Causal Tests

Revised independent preprint, version 1.0.0. This preprint was revised in response to reviewer feedback from the NeurIPS 2026 workshop Interpretability as a Science (InterpScience). It is not an accepted workshop paper or a conference proceedings paper. We distinguish information...

Supporting the Social-Emotional Skills of Preschool Children Through Creative Dance and Musical Stories

Aim: The study aimed to support the social-emotional skills of five- and six-year-old children by utilizing creative dance and musical storytellingMethods: The study was designed using a pre-post quasi-experimental model involving an experimental and a control group. The particip...

Professional identity development in digitally mediated work-integrated learning: a longitudinal qualitative study of paid online tutoring

Purpose This study examines how non-preservice university students developed professional identities through sustained paid online tutoring within a university-designed work-integrated learning (WIL) program. Pupil outcomes were outside the study scope. Design/methodology/approac...

Geopolitics of the Indo-Pacific Security: Navigating the Contours of Power, Contestations and Cooperation

The geopolitics of Indo-Pacific have gained considerable traction in recent years, with the rise of competition between the US and China to shape the course of the 21st century. The regional players adopt diverse approaches to the region based on their strategic interests amid US...

When do positive leader emotions spark employee innovation? The critical catalytic role of humor in transforming affect into meaningful action

Purpose Drawing on the Conservation of Resources (COR) theory, this study examines how leader-triggered positive emotion influences employee innovative work behavior (IWB) through work meaningfulness, and whether leader humor strengthens this indirect relationship. Design/methodo...

The Stanmore Limb Reconstruction Score

Aims: The Stanmore Limb Reconstruction Score (SLRS) has been developed to capture the unique perspective of patients undergoing deformity correction. In this multiphase mixed method approach, face validity has previously been established. This study presents the next stage of val...

Paradoxical bradycardia from occult venous hemorrhage mimicking vasovagal syncope - A case report -

Background: Hemorrhagic shock typically presents with tachycardia; however, profound hypovolemia can paradoxically induce bradycardia via the Bezold-Jarisch reflex. This can lead to misdiagnosis of vasovagal syncope, causing dangerous treatment delays. Case: A 50-year-old woman d...

Characterizing In-Home Safety Challenges and Strategies for Children With Medical Complexity

OBJECTIVES: Medical advances have allowed more children with medical complexity (CMC) to live at home, but previous research has linked implanted tubes to patient safety events. We aimed to characterize challenges and strategies parents use to deliver their children's tube-relate...

The DICTO Hexa: a cube of 8 DICTO Hexa Jewels, the Hexa-Key, and their 5 : 3 checkerboard filling of space

The DICTO Jewel is the regular dodecahedron of the Euclid–Kepler–Pacioli cell carved by the stella octangulas of its six neighbouring cells (volume 12 at cube edge 2); with stella octangulas it fills space. Eight DICTO Hexa Jewels (exact DICTO Jewels on a 2 × 2 × 2 block of cells...

Nonconsensual sexting experiences are associated with bullying and online gossiping victimization among early adolescents in Nicaragua

BACKGROUND: Nonconsensual sexting experiences are a form of image-based sexual abuse that can have serious consequences for the victim. Prior work has found that the forwarding of sexts can happen in negative peer contexts, such as bullying and online gossiping victimization. Thi...

Hybrid Graph Neural Network Ensemble with Stacked Meta-Learning for Laboratory-Conditioned Chromatographic Retention-Time Prediction

Abstract Accurate prediction of chromatographic retention time (RT) is valuable for compound identification in untargeted metabolomics and forensic toxicology, yet validation must account for repeated molecular structures, chemical-space coverage, and heterogeneous laboratory sou...

Quality of Pediatric Rehabilitation Services Across Seven Dimensions: A Scoping Review (Protocol)

Protocol for a scoping review that maps how the seven WHO/OECD/World Bank (2018) quality dimensions (effective, safe, people-centred, timely, equitable, integrated, efficient) are conceptualized, operationalized and measured in pediatric rehabilitation services, with particular a...

When Dense Networks Diffuse Sparsely: A Stochastic Propagation Operator for Weighted Directed Networks

Classical resolvent centralities on weighted networks aggregate propagation over all observed links. We develop a stochastic propagation operator for weighted directed networks in which only a random subset of links is active at each round, impulses may persist, and receiving nod...
