Supramolecular Mask-Mediated Regioselective bis-Bingel-Functionalization of M3N@I h -C80 (M = Lu, Sc)

Abstract Exohedral functionalization of endohedral metallofullerenes (EMFs) is essential for exploiting these intriguing molecules as novel materials in applications such as biomedicine and organic solar cell device design. In the case of trimetallic nitride template EMFs (TNT-EM...

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...

ChatGPT’s feedback credibility and students’ perceived learning: the role of agent-related social perceptions

Abstract This paper examines whether students’ agent-related social perceptions of ChatGPT are associated with the perceived credibility of its feedback in academic tasks and whether such credibility, in turn, is related to students’ perceived learning. It also investigates wheth...

Dissecting Binary and Ternary Iminoboronate Assemblies: A Calorimetric Study of Thermodynamics, Kinetics, and Allosteric Effects

Abstract Dynamic covalent assemblies derived from ortho-boronoaldehydes, including iminoboronates and boronate esters, are key structural motifs in adaptive materials, chemical sensors, and reversible bioconjugation strategies. Herein, we report a label-free assay based on isothe...

Global Incidence of All-Cause Dementia

Importance Global dementia incidence estimates are limited by underrepresentation of low- and middle-income countries and heterogeneous analytic methods. Due to these limitations, true understanding of the global dementia landscape remains incomplete. Objective To identify dement...

Glucose and Oxygen Availability Shape Growth and Architecture of Tumor Spheroids in a Microfluidic 3D Model

Glucose and oxygen availability are fundamental drivers of tumor progression, deeply influencing cancer cell proliferation, metabolism, and spatial organization. In this study, we present a simplified microfluidic-based 3D model of tumorigenesis that allows for controlled and dyn...

Comparing constructions in Romance and Germanic languages

Abstract In recent years, there has been a growing interest in applying Construction Grammar to cross-linguistic comparison. Traditionally, Construction Grammar has been extensively applied to English, to the detriment of other languages, especially Romance languages such as Span...

Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed. Further, these thres...

Towards a contrastive usage-based constructionist methodology for a cross-linguistic comparison of constructions

Abstract This paper presents a programmatic outline of a systematic approach to contrastive linguistic research within Construction Grammar(s) (CxG(s)). We address a number of theoretical and applied problems in Contrastive Construction Grammar, including the following: (1) Defin...

Er ist ganz verrückt nach Batman

Abstract The paper investigates the [Subj experiencer V copula Adj metaphorical PP stimulus ] intensification construction in German, French, and Italian within the framework of Construction Grammar. Based on extensive corpus data from the TenTen family (deTenTen23, itTenTen20, f...

Unhappy Regions and Cities? Urban Agglomeration and Individual Happiness in Spain

ABSTRACT This paper examines how individual subjective well‐being varies across space in Spain, with a particular focus on the roles of city size and long‐term population growth. Using individual‐level data from multiple waves of the Spanish Centre for Sociological Research surve...

Influence of Room Illumination on Corneal Densitometry

Purpose: To evaluate the effect of room illumination on corneal densitometry measurements obtained with Scheimpflug imaging and optical coherence tomography (OCT) and on corneal geometric parameters. Methods: Twenty-five healthy participants (50 eyes) were imaged under four contr...

Effects of specialized pro-resolving mediators and telerehabilitation on fatigue, dyspnea, and quality of life in post‑COVID‑19 condition: the ARACOV-02 randomized controlled trial

Post‑COVID‑19 Condition (PCC) is characterized by persistent multisystem symptoms, with fatigue and dyspnea among the most disabling. Specialized pro‑resolving mediators (SPMs) may modulate chronic inflammation, while telerehabilitation has emerged as an accessible therapeutic st...

Singlet Oxygen-Responsive MRI Contrast Agents

Abstract In vivo imaging detection of singlet oxygen (1O2) produced by photodynamic therapy remains a challenge. To address this unmet necessity, two Gd3+-based multicyclic magnetic resonance imaging (MRI) probes 1 and 2 were synthesized and characterized for their ability to rea...

Physiological load and circadian organization of cardiovascular, autonomic and thermal functions in dry and lactating ewes assessed using biologgers

Context Lactation is a physiologically demanding period in sheep that is characterized by an increase in metabolic and cardiovascular requirements. Although physiological changes during lactation have been well documented, less is known about how lactation affects the circadian o...

Behavior of iron and mineral magnetite particles in redox cycles including direct oxidation in a high temperature reactor

The coupling of iron oxide reduction and its subsequent oxidation is a promising technology for energy storage and recovery. The evolution of the properties of the iron particles along successive cycles is an aspect of obvious relevance in this subject. In the present work, two m...

Self-reported and self-perceived emotional intelligence and trait anxiety in early adolescence: differentiated concurrent associations and sex differences

Abstract Background Trait anxiety is common in early adolescence and is linked to poorer academic and psychosocial functioning. Emotional intelligence has been proposed as a protective factor, but evidence suggests that different emotional components may show distinct positive or...
