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...

A putative nursery pollination mutualism between Japanese Chrysosplenium plants and Nipponorhynchus sawflies

Societal Impact Statement Understanding ecological interactions is increasingly important for biodiversity conservation. This study reveals a unique nursery pollination mutualism between Japanese endemic plants and sawflies. These partners exhibit tightly synchronized life cycles...

Adsorption of Chiral Ir(III) Complexes on Clay Nanosheets: Optical-Purity-Dependent Packing and Amplified Circularly Polarized Luminescence

Abstract Controlling the spatial distribution of photoluminescent molecules within constrained microenvironments remains a fundamental challenge in enhancing their photophysical properties. Herein, we demonstrate that the differential adsorption behavior of enantiopure and racemi...

Parallel Evolution of Bacteroidota as Long-Term Endosymbionts of Insects

Symbiotic relationships significantly transform both symbiont and host biology. The most visible changes include a massive reduction of the endosymbiont genome and the development of specialized host organs, cells, and compartments for symbiont housing. However, insect symbiosis...

A High-Density Supercritical Fluid of H2

Abstract This study aimed to elucidate the structural evolution of supercritical fluid hydrogen (SCF H2) under high pressure. X-ray diffraction was performed on SCF H2 using synchrotron radiation at room temperature. The structure factor S(Q) was observed in a low-Q region at eac...

Disease Name Recognition and Prognosis in Older Patients With Heart Failure

ABSTRACT Objective Health literacy is considered a prognostic determinant for patients with heart failure (HF), and the recognition of disease names could be fundamental to this. This study examined the proportion of patients with HF who recognized their disease name and its asso...

Cutaneous IgG4 ‐Related Disease Accompanied by Granulomatous Vasculitis: A Case Report

ABSTRACT IgG4‐related disease (IgG4‐RD) is a systemic fibroinflammatory disorder characterized by dense infiltration of IgG4‐positive plasma cells, fibrosis, and elevated serum IgG4 levels. Although various cutaneous manifestations of IgG4‐RD have been described, and vasculitic c...

Ultrahigh flow strength in shocked nanopolycrystalline diamond

Extreme pressures and temperatures create conditions that allow even hard and brittle materials to flow plastically. Despite extensive research, the limits of flow strength under such conditions remain uncertain, and the mechanisms driving deformation at the relevant stresses are...

Seasonal variations and controlling factors of nitrogen fluxes at the sediment-water interface in a semi-enclosed inland sea

Abstract. Nitrogen fluxes across the sediment-water interface and nitrogen removal from sediments are essential components of nitrogen cycle in semi-enclosed inland seas. However, the difficulty in observational sampling hinders continuous data availability that is necessary to u...

Assessing the Impact of Sea Surface Temperature Biases in CMIP6 Coupled Models on the North Pacific Westerly Jet

Abstract This study investigates the impact of sea surface temperature (SST) biases on the latitude of the climatological North Pacific westerly jet using multi‐model analyses and atmospheric general circulation model (AGCM) sensitivity experiments. A comparison of atmospheric‐on...

METTL18 is Required for Developmental, Metabolic, and Endocrine Regulation of Mammalian Growth

ABSTRACT Histidine methylation is an evolutionarily conserved but poorly understood post‐translational modification. METTL18 is known to catalyze histidine N τ‐methylation in vitro, yet its physiological functions in mammals remain unclear. Here we show that mouse METTL18 possess...

Topological dimension of the Gromov–Hausdorff and Gromov–Prokhorov spaces

The Gromov–Hausdorff distance is a dissimilarity metric capturing how far two spaces are from being isometric. The Gromov–Prokhorov distance is a similar notion for metric measure spaces. In this paper, we study the topological dimension of subspaces of the Gromov–Hausdorff and G...

Boundedness of Composition Operators in Orlicz–Morrey Spaces

ABSTRACT In this paper, we investigate the necessary and sufficient conditions for the boundedness of composition operators on Orlicz–Morrey spaces. Our results encompass Lebesgue and generalized Morrey spaces as special cases. In addition, we characterize the boundedness of comp...

Screw density in the talar transverse plane is associated with early bone union following arthroscopic ankle arthrodesis: a retrospective comparison of three- versus four-screw fixation

Although arthroscopic ankle arthrodesis (AAA) is a well-established procedure with lower complication rates than open arthrodesis, the optimal screw configuration for stable fixation and reliable bone union remains unclear. We compared outcomes between three- and four-screw fixat...

Peripheral Functionalization of Antiaromatic 5,15-Dioxaporphyrin for the Synthesis of Oligomers

Abstract Partial peripheral functionalization of the antiaromatic nickel(II) 5,15-dioxaporphyrin (NiDOP) was explored to create substituted products suitable as substrates for oligomer synthesis. Syn- and anti-type diaryl-substituted NiDOPs were synthesized from tribromo-substitu...
