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...

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...

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...

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...

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...

Comparative Analysis of Ion and Electron Contributions to Ionospheric Ionization at Auroral and Subauroral Latitudes

Abstract Electron and proton precipitation into the nightside ionosphere is a key process in magnetosphere–ionosphere coupling. Although auroral electron precipitation at –10 keV is traditionally considered the main driver of auroral emissions, recent studies show that keV electr...

Viscoelastic Response of Crosslinked Rubber: Coarse‐Grained Molecular Dynamics and Time‐Temperature Superposition

ABSTRACT The viscoelastic response of crosslinked rubber was investigated using coarse‐grained molecular dynamics simulations combined with time‐temperature superposition. Crosslinked polymer networks containing different numbers of crosslinkers were generated using a dynamic rea...

Attention-Like Hebbian Learning from Quantum Probability Flow and Quantum-Annealer Tests

We propose a quantum probability-flow principle for deriving local learning rules in associative memory. A transverse field defines leakage channels from data states, and minimizing the measured survival loss gives stability-driven updates. For imaginary-time, dephased dynamics,...

Engineering Hidden Ferroelectric‐Like Distortion for Ultralow Thermal Conductivity in Polar van der Waals Tetradymite

ABSTRACT Ferroelectric‐like polar structures enable diverse functionalities through coupling with charge and phonon transport. Although effective in modulating thermal conductivity, the rational design of novel polar materials with intrinsically low thermal conductivity via ferro...

Unscanning by Möbius Inversion (Functional Pearl)

This pearl presents the classical Möbius inversion theorem for posets as a calculation method for inverting scan-like cumulative computations. We model a scan function as summation over principal down-sets of a lower-finite poset: local values are accumulated according to the ord...

Type-II Charge-Transfer Photogating in a DDCI-4/MoS2 Heterojunction Phototransistor

Abstract Molecular sensitization of two-dimensional semiconductors offers a route to enhanced photodetection, yet the interfacial charge-transfer mechanisms that govern gain in these hybrid devices are often inferred rather than directly established. Here, we report a multilayer...

Empowering PolymericMaterials Discovery by ArtificialIntelligence

Abstract Polymeric materials underpin modern technologies spanning energy storage, microelectronics, healthcare and sustainable manufacturing. Yet their rational design remains exceptionally challenging because material performance emerges from complex interactions among molecula...

The Clinicopathological Characteristics and Prognosis of Cholangiolocarcinoma: A Multicenter Study With a Central Pathology Review

BACKGROUND: Cholangiolocarcinoma (CLC) is a rare liver cancer with ≥ 80% ductular configuration (DC). Given its rarity, its clinicopathological characteristics remain poorly understood, and its status as a distinct disease entity remains controversial. We conducted a nationwide m...

Building a Physics-Aware AI Ecosystem for Solid-State Hydrogen Storage Materials

Abstract Hydrogen storage remains a central bottleneck for scalable hydrogen energy systems due to the multiscale and coupled nature of the thermodynamics, kinetics, and microstructural evolution of hydrogen storage materials (HSMs). Although artificial intelligence (AI) has acce...

An orbifold framework for classifying layer groups with an application to knitted fabrics

Abstract Entangled structures, such as textiles and architected materials, are often doubly periodic. Owing to this property and their finite transverse thickness, the symmetries of these materials are described by the crystallographic layer groups. While orbifold notation provid...

Anterior cingulate cortex projections to the amygdala in primates: topographic and layer-specific organization underlying emotion and mood regulation

Abstract Emotion and mood regulation critically depends on interactions between the anterior cingulate cortex (ACC) and the amygdala. However, the detailed architecture of ACC projections to their major targets, the basal (BA) and accessory (AcBA) basal nuclei of the amygdala, re...

Posttraumatic Stress Dynamics and 15-Year Persistence in Great East Japan Earthquake Survivors

Importance Long-term persistence of posttraumatic stress reactions (PTSRs) is a major public health challenge, yet early prognostic markers for decadal outcomes remain poorly characterized. Specifically, the importance of early symptom fluctuations compared with initial cross-sec...
