Analysis of Smoke-Spread Characteristics in Electric Vehicle Fires in a Two-Lane Tunnel with an Arched Ceiling

With the rapid increase in electric vehicle ownership, fire risks associated with electric vehicles in tunnels have attracted increasing attention. In this study, a numerical model of an electric vehicle fire in a two-lane tunnel with an arched ceiling was established using the F...

Corticothalamic circuits drive voluntary physical exercise-mediated relief of surgery-induced negative emotions in mice

Surgery-induced negative emotions (SINE), such as fear and anxiety, are common clinically and hinder postoperative recovery. Although physical exercise is known to modulate various affective disorders, the underlying mechanisms by which voluntary physical exercise alleviates SINE...

Monofluoromethylphenylalanine: A Sensitive 19F Probe for Protein Conformational Dynamics In Vitro and in Cells

Abstract The combination of site-specific incorporation of 19F-labeled unnatural amino acids (UAAs) and 19F nuclear magnetic resonance (NMR) spectroscopy is a powerful strategy for investigating protein structure, dynamics, and interactions. However, commonly used 19F-containing...

Chirality-Induced One-Way Magnetoresistance in Gold Nanocrystals

Abstract Magnetoresistance (MR), a cornerstone for quantum materials and quantum devices, is usually symmetric (sometimes antisymmetric) under magnetic field reversal. Here, we report a chirality-induced one-way magnetoresistance (ChiMR) in gold nanocrystals, where MR is strongly...

Multidimensional Cardiac Phenotyping of Daphnia magna Enables One-Hour Effect-Based Screening of Aquatic Toxicity

Abstract Operational water quality management relies on physicochemical monitoring and targeted chemical analysis, but routine surveillance covers only a prioritized subset of high-risk contaminants and does not capture biological activity from unmonitored chemicals, transformati...

Iron Isotope Fractionation on Vesta Driven by Magma Ocean Process

Abstract Magma oceans represent a pivotal stage in the early evolution of terrestrial planets. Early‐formed asteroids, driven by the decay of 26 Al, may have also experienced such magma ocean processes. To investigate potential magma ocean differentiation on asteroid 4 asteroids,...

Evaluation of Leucine in Hydrate-based CO2 Separation Technology for Synthesized Mixture Gas

Abstract To increase the combustion calorific value, reduce the greenhouse effect of CO2, and prevent corrosion to pipelines, impurity gases such as CO2 and N2 in biogas must be effectively removed. This study investigates the effects of leucine (Leu) on the kinetics and gas sepa...

Optimal estimators and tests for reciprocal effects

The $p_1$ model plays a fundamental role in modeling directed networks, where the reciprocal effect parameter $ρ$ is of special interest in practice. However, due to nonlinear factors in this model, how to estimate $ρ$ efficiently is a long-standing open problem. We tackle the pr...

Stochastic dominance for linear combinations of infinite-mean risks

Abstract We establish a sufficient condition for comparing linear combinations of independent and identically distributed infinite-mean random variables under the usual stochastic order. We introduce a new class of distributions that includes many commonly used heavy-tailed model...

Termination-Dependent Surface States and Magnetic Fingerprints of Chiral Helimagnet Cr1/3TaS2

Abstract Chiral helimagnets based on intercalated transition-metal dichalcogenides, characterized by nanoscale spin ordering, provide a powerful route to engineer chiral spin textures (e.g., the topologically protected magnetic solitons) and explore emergent electronic functional...

ChemE-MTDS:Multi-Turn Dialogue Data Synthesis and Quality-Controlled Fine-Tuning for Chemical Engineering Large Language Models

Large language models (LLMs) have demonstrated remarkable capabilities in natural language understanding and reasoning. However, their performance in multi-turn dialogues within specialized domains, such as chemical engineering, remains limited due to the lack of high-quality, co...

Facile Fabrication of Double-Shell PA-MEL@PU@CFO Microcapsules and Their Fire Suppression Performance in Confined Spaces

Novel double-shell PA-MEL@PU@CFO microcapsules were successfully prepared by further coating the as-prepared PU@CFO microcapsules with the outer shell of phytic acid-melamine salt (PA-MEL). The fire suppression performance was then investigated in a simulated confined space exper...

Synergistic Dual‐Photoreaction Crosslinking Enables High Phosphoric Acid Retention in High‐Temperature Proton Exchange Membranes

ABSTRACT Phosphoric acid (PA)‐doped high‐temperature proton exchange membranes (HT‐PEMs) enable anhydrous proton conduction but remain limited by PA migration, excessive swelling, and conductivity decay. Here, anthracenylmethyl groups are introduced into PEEK side chains through...

Machine learning empowered compositional design of multiple rare-earth principal component disilicates

Abstract The targeted design of multi-RE-principal-component RE2Si2O7 disilicates ((nRExi)2Si2O7) for environmental barrier coatings (EBCs) applications requires customizing the multi-RE compositions to achieve maximal optimization of the target properties. A critical prerequisit...

Injectable Hydrogel Loaded With Umbilical Cord Blood‐Derived Exosomes Promotes Periodontal Bone Regeneration via the TLR4/NF‐κB Signalling Pathway

ABSTRACT Periodontitis is an immune‐mediated inflammatory disease characterised by progressive alveolar bone loss, which can lead to tooth loss in severe cases. Existing therapeutic agents have limited efficacy in reversing the associated inflammatory bone defects. Exosomes (Exos...

Nanopore-Induced Thickness Independence of In-Plane Thermal Transport in Few-Layer Graphitic Carbon Nitride

Abstract Although in-plane thermal transport in many two-dimensional (2D) materials exhibits pronounced thickness dependence, it remains unclear whether this behavior persists in intrinsically porous 2D systems. In this work, we employ a scalable, high-accuracy atomistic simulati...
