Octahedral tilt relaxation decoupled from lattice parameters in epitaxial perovskite oxide films

Epitaxial strain in perovskite oxide thin films is conventionally understood through lattice parameter modulation, characterized by the c / a ratio of the pseudocubic cell. However, internal atomic arrangements such as octahedral tilting can relax independently, a phenomenon that...

Towards responsible AI in workplace-based assessment: a scoping review using Downing’s framework

This scoping review maps generative AI applications in workplace-based assessment (WBA) and analyzes validity evidence through Downing’s framework. Following JBI methodology and PRISMA-ScR guidelines, four databases were searched (2022-February 2026) with dual-AI screening and hu...

TBK1 eliminates aggregation-prone monomeric TDP-43 through an IFNβ-immunoproteasome pathway in ALS models

Abstract Loss-of-function mutations in TANK-binding kinase 1 (TBK1) cause amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), characterized by cytoplasmic aggregation of TAR DNA-binding protein 43 (TDP-43), known as TDP-43 pathology, but the mechanisms beyond i...

Development and characterization of low-scattering vanadium nanoparticle targets for short-range interaction searches

We developed high-purity vanadium-based nanoparticle targets for neutron scattering experiments aimed at exploring gravity-like short-range new interactions in the submicron regime. Vanadium and V-Ni nanoparticles were fabricated using top-down and bottom-up methods and quantitat...

Late Triassic adakitic rocks in the Selenge igneous rock complex, northern Mongolia: petrogenesis and tectonic implications

In northern Mongolia, in the region along the southern margin of the former Siberian continent, Permian–Triassic adakitic rock complexes formed by the melting of the oceanic slab are widely exposed (Selenge Igneous Rock Complex: SIC). However, the petrogenesis of the SIC remain i...

Host–Dopant Engineering of Ce 4+ ‐Dominant Y 3 (Al,Ga) 5 O 12 :Ce,Mg Scintillators for High‐Performance X‐Ray Imaging

ABSTRACT Fast scintillators are essential for advanced X‐ray imaging and time‐of‐flight techniques. Although stabilizing Ce 4+ ions in garnet hosts is an effective strategy for suppressing the afterglow and accelerating scintillation, it often introduces quenching pathways that r...

Noncatalytic Synthesis of High‐Density and Small‐Diameter WS 2 Nanotubes

ABSTRACT A substrate‐engineered, noncatalytic strategy is developed for the controlled synthesis of high‐density WS 2 nanotubes by decoupling nanowire precursor growth from vapor‐phase sulfuration. The process enables precise structural control and yields dense nanotube networks...

Astrocytic cathepsin D promotes α-synuclein processing and Lewy neurite-like aggregate maturation

Abstract Parkinson’s disease (PD) and related synucleinopathies are marked by the accumulation and propagation of α-synuclein (α-syn) aggregates, a process primarily studied in neurons. Whether astrocytes actively contribute to α-syn processing and intercellular transfer remains...

Effects of d-allulose intake during exercise training on heart rate response to submaximal exercise in untrained young adults: a pilot study

[Purpose] d-Allulose has been reported to enhance fat oxidation during acute aerobic exercise; however, its effects during exercise training in humans remain unclear. We investigated the effects of d-allulose intake during exercise training on physiological responses to submaxima...

A Residue-Resolved Mechanism for Trapped-Twist Spectral Tuning in Cyanobacteriochromes

Abstract Cyanobacteriochromes (CBCRs) are bilin-binding photoreceptors that photoconvert between long-lived, thermally stable states; in the red/green subfamily, photoexcitation converts the red-absorbing Pr state to the green-absorbing Pg state with a large blue shift. Here we q...

Sexual segregation in foraging behavior varies with breeding site and year in seabirds

Abstract In many animals, behavioral sex differences can produce spatial or temporal segregation, known as sexual segregation, which is thought to reduce competition and satisfy sex-specific physiological demands. In breeding central-place foraging seabirds, sexual segregation ma...

Terahertz time-domain spectroscopy as a novel tool for crystallographic analysis in cellulose: insights into the complex lattice interaction with water molecules

This study explored a method for investigating crystalline cellulose and its interaction with water molecules using terahertz time-domain spectroscopy (THz-TDS). Cellulose-lignin composite samples with different cellulose contents were placed under varying humidity conditions to...

From Instruction to Inheritance: Scaling Robot Learning Through Knowledge Circulation

Robot learning, particularly through vision–language–action (VLA) models, has rapidly improved the ability of robots to execute instructed tasks. However, the current mainstream paradigm of robot learning largely depends on one‐way instruction from humans to robots, lacking a cyc...

Hydroalkylation and hydroacylation of trifluoromethyl olefins by N-centered direct hydrogen atom transfer photocatalysis

The selective functionalization of trifluoromethyl olefins, while keeping the essential trifluoroalkyl moiety intact, remains a synthetic challenge. In this study, we report the use of an acridinium amidate as a direct hydrogen atom transfer (d-HAT) photocatalyst for the mild and...

Direct galaxy--galaxy morphology chirality: A Wigner function shapelet framework for three-dimensional parity tests

Galaxy images encode internal morphology through phase relations that are not retained by low-order shape summaries. We formulate a three-dimensional parity test that directly couples the Wigner function shapelet (WFS) modes of two galaxies before compressing either image into a...

Diffusion Geometry for Galaxy Bulk-Flow Reconstruction I: Foundations and Full-Vector Validation

We formulate a diffusion-spectral field-reconstruction framework based on diffusion geometry for reconstructing cosmological vector fields from finite and nonuniformly distributed galaxy point clouds. Low-frequency eigenfunctions of a Markov operator defined on the point cloud ar...

Rapid genome-wide purging following tsunami-induced hybridization in a stickleback population

Speciation is the process by which barriers to gene flow evolve between populations. As speciation approaches completion, genome-wide divergence can be maintained in the face of hybridization. Because real-time observations of genomic changes following hybridization in natural po...

Diffusion Geometry for Galaxy Bulk-Flow Reconstruction II: Three-Dimensional Potential-Flow Reconstruction from Radial Velocities

Reconstructing a three-dimensional velocity field from radial peculiar velocities is non-identifiable because the radial observation operator has a large null space, even when a finite design matrix is formally full rank. Building on Paper I, we construct a potential-flow-constra...

Neighborhood interaction at age 65 and subsequent initiation and cessation of social participation in Japanese older adults: the NISSIN Project

Whether neighborhood interaction is differently associated with initiation and cessation of social participation in early old age remains unclear. We analyzed 1,688 Japanese adults surveyed at ages 65 and 70. Initiation and cessation were examined separately using modified Poisso...
