Direct Observation of Propagating Spin Waves in a Spin Hall Nano‐Oscillator

Constriction-based spin Hall nano-oscillators (SHNOs) show great promise for application as highly tunable microwave sources with straightforward scalability toward large coupled networks. However, details of the magnetization dynamics within SHNOs have thus far not been addresse...

Mitigating Water Evaporation in Aqueous Liquid-Based Direct Air Capture Using Supported Ionic Liquid Membranes

The stability and efficiency of direct air capture (DAC) processes using liquid absorbents are significantly influenced by solvent volatility. This study investigated CO2 recovery performance and absorbent weight loss of aqueous potassium hydroxide (KOH)-based DAC incorporated wi...

Design of Carbon Capture System Utilizing Wolffia globosa and CaO Derived From Waste Seashells With Continuous Real‐Time IoT ‐Based Monitoring

ABSTRACT This study presents the design and implementation of a prototype‐scale hybrid CO 2 capture system that combines Wolffia globosa cultivation, mineral carbonation with waste seashell‐derived CaO, and real‐time IoT‐based monitoring. Waste seashells were calcined at 900°C to...

Taxonomic reassessment and palaeobiogeographical patterns of some Miogypsinidae species, larger benthic foraminifera

Abstract. The Miogypsinidae comprise orbitoidal larger benthic foraminifera with generally eccentric position of the nepionic stage and a fan of equatorial chamberlets; the members of this family are widely used in biostratigraphy of upper Oligocene–middle Miocene deposits. Here,...

Photocatalytic proximity labeling for the identification of G-quadruplex DNA-interacting proteins

Abstract DNA–protein interactions play an essential role in fundamental cellular biological processes. Herein, we report a photocatalytic proximity labeling approach for the broad screening of G-quadruplex (G4)-interacting proteins (G4IPs) using human telomere G4 DNA modified wit...

Development and Validation of a Prediction Model for Alarm-Triggered Interventions in Pediatrics

BACKGROUND: Alarm fatigue in pediatric wards stems from frequent, nonactionable alarms that do not lead to clinical intervention. Predicting alarm-triggered clinical interventions is essential for optimizing monitoring strategies. OBJECTIVE: To identify factors associated with al...

Validation and uncertainties of strong ground motion prediction methods for seismic hazard assessment: a case study of the 2024 Noto Peninsula earthquake (Mw7.5), Japan

Abstract The major active fault earthquakes in Japan in recent years include the 2016 Kumamoto Earthquake and the 2024 Noto Peninsula earthquake. These earthquakes occurred along predicted fault models, however, uncertainties and variations in fault geometry and rupture propagati...

Analysis of Critical Points in a Permutation Model on Hierarchical Lattices by Real-Space Renormalization Group

The permutation model is a classical spin system where elements of the symmetric group interact with one another. The partition function of this model is directly related to the entanglement structure of random quantum circuits and random tensor networks. In these contexts, the e...

Multi‐fidelity Monte Carlo fusion for BNCT dose calculation using a dual‐branch network

BACKGROUND: Boron neutron capture therapy (BNCT) is a binary radiotherapy that selectively kills tumor cells. Its clinical implementation relies on Monte Carlo (MC)-based treatment planning systems, which are time-consuming and limit clinical workflow efficiency. PURPOSE: To addr...

Photo-triggered construction of nitrogen-containing aromatic heterocycles under physiological conditions

Abstract Precise spatiotemporal control of molecular function is essential for probing biological systems and developing safer therapeutics. Herein, we review photoinducible intramolecular cyclization reactions developed in-house for generating nitrogen-containing aromatic hetero...

Antiferromagnetic order and crystalline electric field in noncentrosymmetric hexagonal R E Ru 6 As 4 ( R E = Sm and Yb )

We investigated the electronic properties of $RE{\mathrm{Ru}}_{6}{\mathrm{As}}_{4}(RE=\mathrm{La}, \mathrm{Ce}, \mathrm{Sm}, \text{and} \mathrm{Yb})$ using single-crystalline samples grown by the Bi-flux method. These compounds crystallize in the noncentrosymmetric hexagonal ${\m...

Prediction-based sign placement using QA sampling

We present a pedestrian-flow forecasting and sign-placement workflow that leverages quantum annealing (QA) not as an optimizer, but as a sampler of individual trajectories. To reconstruct latent crowd dynamics from sparse measurements, we formulate a quadratic unconstrained binar...

Time-Temperature-Transformation Diagrams to Navigate the Nucleation and Quenchability of Metastable α-Li₃PS4

α-Li₃PS₄ is a promising solid-state electrolyte with the highest ionic conductivity among its polymorphs. However, its formation presents a thermodynamic paradox: the α-phase is the equilibrium phase at high temperature and transforms to the stable γ-Li3PS4 polymorph when cooled...

Event-related potentials to emotional incongruence in dogs using non-invasive EEG

Abstract Previous behavioral and autonomic studies suggest that dogs are sensitive to their human emotional expressions, yet the neural mechanisms underlying how such information is processed across modalities remain unclear. This study investigated whether dogs exhibit different...

Electrodeposited Bi2Te3-carbon black nanocomposites with enhanced thermoelectric and mechanical properties

Thermoelectric thin films based on bismuth telluride (Bi 2 Te 3 ) are widely used for room temperature energy harvesting, but improving electrical, thermal, and mechanical properties simultaneously remains challenging. In this study, Bi 2 Te 3 -carbon black nanoparticle nanocompo...

P1.046. Pedicled Omental Flap Preserving the Right Gastroepiploic Artery for Gastric Conduit Reconstruction in Multistage Surgery for Aortoesophageal Fistula

Abstract Topic Benign Disease: Other Background Aortoesophageal fistula is a rare but highly fatal condition. Thoracic endovascular aortic repair has led to improved early outcomes. However, subsequent aortic replacement, esophagectomy, and gastrointestinal reconstruction are req...

Characteristics of Quasi-stationary Band-shaped Precipitation in the Tohoku Region Detected under Varying Rainfall Thresholds

Abstract Quasi-stationary band-shaped precipitation systems sometimes cause severe rainfall disasters in the Tohoku region of northeastern Japan, but the uniform rainfall thresholds used in existing objective detection methods may be too high for this region. This study examines...

Geneformer-guided multiomics integration identifies Pbx1 as a network hub of hematopoietic stem cell aging

Hematopoietic stem cells (HSCs) constitute an organized hematopoietic system that undergoes age-related alterations, including increased platelet production and decreased erythropoiesis. The fundamental mechanisms driving these shifts remain incompletely understood. We used singl...

PPARG directs trophoblast cell fate and establishment of the uterine-placental interface

Abstract The expansion and differentiation of trophoblast stem (TS) cells are critical for defining fundamental properties of the placenta. Specialized trophoblast cells called extravillous trophoblast (EVT) cells in human and invasive trophoblast cells in rat, exit the placenta,...

Finite-Basis Duality Estimate for the Surface-Code Threshold under Correlated Bit-Flip Errors

We apply finite-basis duality to a statistical-mechanical model introduced by Chubb and Flammia for the surface code under spatially correlated bit-flip noise, for which their mapping gives a random-bond Ising model with both two-body edge interactions and four-body face interact...
