A Diamagnetic Six-Coordinate Ag(III) Complex

Abstract The octahedral complex AgIII(CF3)3tpy (2Ag), attainable from AgIII(CF3)3py (1Ag) and terpyridine (tpy), has been isolated and characterized using NMR spectroscopy and Sc-XRD. Strikingly, 2Ag proved to be diamagnetic and showed tridentate coordination of the tpy ligand, t...

MnBn(CO)5-Catalyzed Cascade C–H Activation/Annulation to Construct Bridged N -Heterocycles

Abstract Herein, a manganese-catalyzed synthesis of bridged heterocycles via a C–H activation/annulation cascade between azomethine imines and Morita–Baylis–Hillman adducts is described. MnBn(CO)5 serves as a highly active catalyst, exhibiting unique and remarkable capability in...

Harassment and structural violence against abortion providers in Colombia: A national mixed‐methods study

OBJECTIVE: To examine the discrepancy between a single-item harassment screening and a behaviorally anchored stigma scale among Colombian physicians who provide voluntary termination of pregnancy (VTP), and to explore how providers who do not identify as victims describe their ex...

Exploring the Modalities of Combining Biological Models

Abstract This article examines how biological models are combined in biomedical research. It analyzes the notion of epistemological space, understood not as an abstract space of epistemic possibilities but as a framework for coordinating heterogeneous models through zones of part...

Mapping Technological Civilization in State Space: From Planetary Vital Signs to Multidimensional Risk Configurations

Global-risk assessments are usually communicated as lists, rankings, likelihood–impact matrices or networks of interconnections. These instruments are useful, but they represent poorly a basic property of the world system: its condition is a simultaneous configuration of many int...

Genome-Wide Marker–Trait Analysis of Agronomic and Biomass-Related Traits in an Interspecific Miscanthus F1 Population Grown on Reclaimed Mine Land

Miscanthus is a perennial bioenergy crop suited to marginal and degraded land, yet relatively little is known about the genetic basis of biomass-related variation in interspecific hybrids across years. We evaluated 100 F1 genotypes from Miscanthus sacchariflorus × M. lutarioripar...

Improving the Circular Economy in the Iberian Pyrite Belt: Upcycling Mining Legacy Materials into Sustainable Cement-Based Composites

The mining sector is in urgent need of circular economy strategies to manage its historical environmental liabilities. This study investigates the upcycling of mining legacy materials from the Iberian Pyrite Belt (IPB) as sustainable substitutes for natural fine aggregates in cem...

Evolution towards monomorphy leads to a loss of morph plasticity in wing polymorphic crickets

Threshold traits are widespread forms of dimorphism in which an underlying continuous liability produces discrete phenotypes once a threshold is crossed. The threshold trait model predicts that phenotypic variation will be observed only when the distribution of liability spans th...

Semaglutide in Patients with Obesity and Psoriasis: Insights from an 18-Month Real-World Experience

Psoriasis is often associated with obesity and type 2 diabetes mellitus (T2DM) due to a common low-grade chronic inflammatory mechanism amplified by metabolic dysfunction. Biologics have revolutionized psoriasis treatment, but patients with obesity show reduced responses and high...

A cross-sectional analysis and forward projection of China’s gallbladder and biliary-tract cancer burden

Gallbladder and biliary tract cancer (GBTC) remains highly lethal. We examined 32-year epidemiological trends in China and projected outcomes to 2050. Using 2021 Global Burden of Disease (GBD) data, we extracted annual GBTC incident and prevalent cases, deaths, and disability-adj...

Navier-Stokes Problem Remains Unsolved: No Verified Breakthrough Found — E8 Intelligence Research

FINDING: The Navier-Stokes existence and smoothness problem remains open; the search results are educational expositions and one preprint claiming a new method, but no verified breakthrough or novel mathematical constant emerges. | MATH: The core system is the incompressible Navi...

Corporate social responsibility and employee motivation: intrinsic and extrinsic pathways in Vietnamese SMEs

Purpose This study aims to conceptualize corporate social responsibility (CSR) as a potentially need-supportive organizational context. This study examines how CSR-related autonomy, competence and relatedness are associated with employees’ intrinsic and extrinsic motivation and h...

Neutrophil to Lymphocyte Ratio and Neurological Outcome in Ischemic Stroke at 4.5 to 24 Hours: A Post Hoc Analysis of TRACE-III Trial

Whether neutrophil to lymphocyte ratio (NLR), as a marker of increased inflammatory response, modifies the efficacy and safety of tenecteplase is uncertain in patients 4.5–24 h after stroke onset. We investigated this in the Tenecteplase Reperfusion Therapy in Acute Ischemic Cere...

Is active commuting to school associated with meeting physical activity recommendations among Saudi adolescents? A cross-sectional study

Rising rates of physical inactivity (PI) among adolescents represent urgent public health concern. Encouraging students to actively commute to school (walking or cycling rather than relying on motorized transport) is a scalable strategy to increase habitual physical activity (PA)...

Crack parameter inversion using an ultrasonic-magnetic fusion neural network

Crack defects in ferromagnetic components may lead to structural degradation and safety risks during manufacturing and service. Ultrasonic testing and magnetic memory testing have complementary advantages, but single-modality methods are often limited in quantitative crack parame...

Mechanical Behavior of Layered Heterogeneous Hydrate-Bearing Sediments: Insights from Triaxial Experiments and Numerical Modeling

Abstract The mechanical behavior of natural gas hydrate-bearing sediments (HBS) is critical for safe and efficient gas production. However, marine HBS commonly exhibit layered heterogeneity caused by spatial variations in clay distribution and hydrate saturation (Sh), whose effec...

A multi-component professional ethics education program incorporating AI-assisted learning for nursing students: changes in moral reasoning in a quasi-experimental study

Moral reasoning is an essential professional competency in nursing and supports ethical decision-making. This study examined changes in moral reasoning following a multi-component professional ethics education program incorporating AI-assisted case exploration, compared with the...

Family migration and gender inequality in housework: Evidence from China

While the impact of family migration on paid work is well-documented, its potential influence on housework remains largely unknown. This study examines the effect of couple migration on the division of housework in China, focusing on changes in housework hours for both female and...
