Pd(II)-Templated End-to-End Cyclization of Doubly N-Confused Bilatrienes: A Stable Singlet Diradicaloid Dye with Efficient Absorption across the Solar Spectrum

Abstract We report a highly stable singlet diradicaloid (Pd1-dimer), formed through a Pd(II)-templated end-to-end cyclization of a linear N-confused bilatriene (1). This unique Pd-bridged double-loop complex exhibits an open-shell singlet diradicaloid ground state with an extreme...

Beamstop-free small-angle X-ray scattering for multiscale structure measurement of high-energy-density plasma

The advent of free-electron lasers has enabled in-situ small-angle X-ray scattering (SAXS) measurements of laser-produced high-energy-density plasma at solid density, with nanometer- and femtosecond-scale resolution. Such plasmas generally exhibit gentle density gradients, which...

Structural insights and comparative electrocatalytic performance of citric acid-functionalized Luffa aegyptiaca and Pt-Pd/MWCNT-Luffa composites for the degradation of acetaminophen in aqueous media

Emerging contaminants, such as acetaminophen, pose a critical threat to aquatic ecosystems and human health due to their persistence in water and the difficulty of their removal using conventional methods. In this work, Luffa aegyptiaca biomass was valorized via citric acid funct...

Numerical investigation of radiative heat transfer effects on liquid ammonia jet spray flames

Radiative heat transfer in liquid-ammonia spray flames remains poorly understood, particularly because liquid evaporation, fuel-side mixing, and product-side heat release are spatially separated. In this study, radiative heat transfer in a spatially developing liquid-ammonia jet...

Guest-Induced Chirality Transfer in Trimers of Invertible Cylinder-Shaped Macrocycles

Abstract Transfer of chiral information is abundant in biological processes. To mimic them in artificial systems, chiral macrocyclic molecules are particularly promising components for their simplicity and easy-to-predict intermolecular interactions. Herein, we report a chirality...

Geometric quantum thermodynamic engine under an isothermal operation: an application of a Thouless pumping

Abstract We present a geometric formalism for the non-equilibrium thermodynamics of a small system coupled to external isothermal reservoirs as an application of Thouless pumping, where the electro-chemical potentials of the reservoirs and parameters in the system ʟs Hamiltonian...

Autoimmunity induced by epigenome alteration affecting thymic Treg cell development

Methyl-CpG-binding domain protein 3 (MBD3), an essential component of the nucleosome remodeling and deacetylase (NuRD) complex, controls chromatin accessibility at lineage-specific transcriptional enhancers and promoters during hematopoietic cell differentiation. Here, we have sh...

A hydroinformatics framework for multisource precipitation merging and SPI-based drought monitoring in Eswatini

ABSTRACT Graphical summary of the study. A map of Eswatini shows elevation, agroecological zones, and training and testing rain gauges. AgERA5, ERA5-Land, ARC2, and CHIRPS are combined in four precipitation configurations and modelled using Random Forest and XGBoost, with and wit...

Local Generation of Plasmaspheric Plume Hiss

Abstract The statistical analysis of hiss waves observed in the plasmaspheric plume (Wu et al., 2026, https://doi.org/10.1029/2026gl121667 ) is significant for identifying nonlinear wave growth processes in the equatorial region. Because nonlinear growth rates greatly exceed line...

Neglected carbonation effect on moisture profiles in hardened cement paste during short-term drying

This study investigates the influence of atmospheric CO₂ on moisture transport during drying in cementitious pastes with different microstructures, namely ordinary Portland cement (OPC), volcanic glass powder (VGP), and limestone-calcined clay cement (LC 3 ) pastes. To isolate th...

Carbonic anhydrase VIII regulates IP3R1-dependent Ca 2+ signaling to coordinate insulin secretion and hepatic glucose production

Intracellular Ca 2+ signaling is essential for glucose-induced insulin secretion (GIIS) and hepatic glucose production (HGP), yet how Ca 2+ dynamics are coordinated across organs remains unclear. Carbonic anhydrase VIII (CA8), an endogenous inhibitor of inositol 1,4,5-trisphospha...

2026 revised CVIT clinical expert consensus on drug coated balloons for coronary artery disease

Abstract Drug-coated balloons (DCBs) are attracting attention as a therapeutic alternative to drug-eluting stents (DES) in percutaneous coronary interventions. DCB technology allows direct delivery of antiproliferative drugs to the vessel wall without implantation of a permanent...

Coordination‐Driven Direct Conversion of Layered Metal Borides Into Borophene/MOF Heterostructures

ABSTRACT Engineering robust two‐dimensional material/metal‐organic framework (MOF) heterostructures with well‐defined interfaces remains challenging, largely because conventional routes depend on sequential etching, exfoliation, and self‐assembly steps that are inefficient, reage...

Pyroglutamyl peptide–rich rice protein hydrolysate restores cecal N -acetyl amino acids in high-fat-diet–fed rats, outperforming short-chain fatty acids as early microbial markers

Abstract Pyroglutamyl-leucine (pyroGlu-Leu) is a food-derived modified peptide known to modulate the gut microbiota. This study examined the effects of orally administered rice protein hydrolysate (RPH) containing pyroGlu-Leu in rats fed a 45% high-fat diet that induced mild dysb...

Olive Oil Before Oral Glucose Delays Gastric Emptying and Lowers Glycemia Through Partially Redundant Glucagon and GLP-1 Signaling in Mice

Consumption of fat before carbohydrate (preload) attenuates postprandial glucose excursions, although the underlying mechanisms remain unclear. We investigated whether an olive oil preload (OG) reduces glycemia by engaging endocrine and neural regulation of gastric emptying. Wild...

Mapping and Modeling Interfacial pH Dynamics at Enzymatic Microelectrode

Abstract Redox enzymes are promising biocatalysts for energy conversion and sensing, particularly when immobilized on electrodes to facilitate charge transfer and enhance stability. While they offer the advantages of operating under mild conditions and near-neutral pH, high react...

Confined Water Wires as Anisotropic Proton Highways in a Neutral Polymer Single Crystal

Abstract Directional proton transport is central to bioenergetics and emerging electrochemical technologies, yet achieving high and anisotropic proton conductivity in fully covalent, charge-neutral crystalline materials remains a challenge. Here, we report anisotropic proton cond...

Emotional predictors of returning a favour: Behavioural experiments in the United States and Japan

Abstract We examined emotional predictors of favour‐returning behaviour in the United States (Study 1) and tested whether the findings in the United States would replicate in a culturally different context in Japan (Study 2). In both experiments, participants played a collaborati...

An integrated model of executive function, AI literacy, and Chinese L2 reading comprehension among ethnic minority adolescents in Hong Kong

Artificial intelligence (AI) is increasingly embedded in second language (L2) learning, yet the cognitive demands of AI-mediated environments, particularly for logographic languages such as Chinese, remain underexplored. This study investigated the interrelationships among execut...

Damage identification and model updating using bridge displacement under moving vehicles with uncertain weight

Bridge damage incurred during long-term service leads to discrepancies between the physical structure and its digital twin finite element (FE) model, necessitating regular model updates to ensure reliable health monitoring. Traditional methods typically adopt a two-step framework...
