The Fox Versus the Hedgehog: Firm Survival During Unprecedented Crises

This paper examines how sales channel diversification influences firm resilience during the COVID crisis. Drawing on a series of logit regressions analyzing 11,662 firms across 31 developing countries, we find that firms embodying an open mind-set and a diverse array of sales cha...

AI in Journalism Education: Curriculum Development and Implementation of Journalism in BRICS Universities

This study employs content analysis and semi-structured in-depth interviews to examine how journalism education across BRICS countries has responded to the rise of AI and adjusted its core paradigms. In this study, BRICS refers to the expanded BRICS grouping, comprising Brazil, R...

Detection of the elusive cyclo−1,2-dihydrotetrazete (N4H2) in the gas phase

Nitrogen hydrides (NnHm) have attracted significant interest for their potential in developing high-energy-density materials. The synthesis of cyclic nitrogen hydrides is particularly challenging due to their inherently high strain energies. Here we report the preparation of the...

Combining H2O2-SupplyingIron Peroxide Nanoclusters with GSH-Depleting Gold Nanoclusters forEnhanced Chemodynamic Therapy via Amplification of Oxidative Stress

Abstract Chemodynamic therapy (CDT), which employs •OH generated by Fenton-type reactions to trigger cancer cell death, has received much attention in recent years. However, CDT efficacy is restricted by insufficient H2O2 levels and reactive oxygen species (ROS) consumption by an...

Same formation, different styles: An exploratory study of clustering playing style of teams in 4-3-3 formation in elite soccer

This study examined whether teams using identical formations display similar playing styles by integrating Phase of Play (PoP) indicators with clustering and explainable machine learning. Ninety-three observations from teams employing a 4-3-3 formation in the FIFA World Cup 2022...

Distinct Spatiotemporal Dynamics of Thermoelectric Transport Across Superconducting Transition

Abstract We investigate the relaxation dynamics of heat transport in superconductors, shaped by the interplay of diffusion, nonlinearity, and magnetic fields. Focusing on regimes near the critical temperature T c , we analyze two classes of relaxation-diffusion equations that giv...

Measurement and comparative analysis of owner-occupied housing services in China

Purpose This paper aims to address the historical underestimation of China’s owner-occupied housing services (OOHS) scale and the 2024 accounting reform by the China’s National Bureau of Statistics – which adopted the market rent approach for urban areas but did not revise histor...

Reliability and diagnostic performance of radiologic indices of the proximal humerus in evaluating bone mineral density: a retrospective study

Proximal humerus fractures (PHFs) are the third most common osteoporotic fractures. Assessment of bone mineral density (BMD) is clinically relevant in patients with PHFs. Several studies have proposed the use of radiologic indices, including the average cortical bone thickness (C...

Nitrogen-RichPyrogenic Carbon-Induced Hydroxyl RadicalGeneration During Sulfide Oxidation: An Unrecognized Polysulfide RadicalChain Propagation Mechanism

Abstract Sulfide oxidation mediated by pyrogenic carbon (PyC) is critical for initiating reactive oxygen species (ROS) generation in subsurface systems. Nitrogen-rich pyrogenic carbon (N-PyC), containing abundant heterocyclic N, serves as a highly reactive component of the PyC po...

Where Can a Threatened Pheasant Persist? Identifying Climate Change Refugia and Mapping Protection Gaps in China

Climate change and human activities are widely recognized as major drivers of global biodiversity loss. The Brown Eared Pheasant (Crossoptilon mantchuricum), a ground-dwelling avian species unique to China, is confined to a highly fragmented range and faces persistent long-term t...

Quantifying the impact of urbanization and climate change on event-based extreme precipitation in Guangdong Province, China

Study region Guangdong is located on the southern coast of mainland China and is the province with the highest level and fastest pace of urbanization in the country. Study focus This study investigates how five characteristics of hourly event-based extreme precipitation (HEEP) va...

From Data to Decision:A Closed-Loop Framework forCo-Optimizing Energy Recovery and SO2 Control in SludgeGasification

Abstract The rapid expansion of urban wastewater treatment has rendered the sustainable management of sludge a global environmental challenge. Gasification technology is emerging as a promising treatment pathway due to its high conversion efficiency and resource recovery potentia...

Global cloud phase monitoring from FY-3G multi-angle polarimetric observations using the new MAPLE-CP framework with independent multi-site lidar validation

Global cloud-top phase monitoring is constrained by an observing gap: passive imagers provide broad coverage but limited vertical phase information, whereas active sensors provide stronger physical constraints only along narrow tracks. Here we develop MAPLE-CP, a Multi-Angle Pola...

Developmental Relations Between Oppositional Defiant Disorder and Depression in Childhood: A Symptom Level Perspective

Background Oppositional defiant disorder (ODD) has substantial comorbidity with depression. However, their comorbidity at the symptom level, including potential gender differences, is currently underspecified. This study aimed to explore the comorbidity network of ODD and depress...

Evolutionary Progress and Cultural Value: An Analysis of the Divergence Between Ernan McMullin and Michael Ruse

The relationship between science and values is a classic and important issue in the philosophy of science. Ernan McMullin, a philosopher of science, believes that as science matures, the pursuit of epistemic values leads to the gradual exclusion of non-epistemic values. Michael R...

Photovoltaic Microhabitats Reorganize Vegetation and Soil Carbon Pools in an Alpine Dryland Grassland

Utility-scale ground-mounted photovoltaic development is expanding across alpine dryland grasslands, creating engineered microhabitats with contrasting shading regimes, surface exposure, and soil hydro-physical conditions. Microhabitat-specific responses of vegetation and soil ca...
