Phase-dependent high-temperature oxidation behavior of multiphase Ti2AlNb alloy

Environmental degradation of Ti 2 AlNb alloys is intrinsically coupled with their multiphase constitution, yet the local mechanisms by which individual phases mediate oxidation remain insufficiently resolved. Here, we reveal the phase-selective high-temperature oxidation behavior...

Beam layout design in shear wall structures using a diffusion model guided by rule-based masks

Serving as critical load supports and transfer components in shear wall structures, beams require layout designs that balance mechanical rationality with architectural functionality constraints. Conventional design methods, which rely on engineers' expertise, are challenging to s...

China regional 3 km downscaling based on residual Corrective Diffusion model

A fundamental challenge in numerical weather prediction is efficiently producing high-resolution forecasts. A widely adopted solution is to downscale coarser global model outputs. This study focuses on statistical downscaling, which uses historical data to learn mappings between...

Differential Psychological Effects of Daytime and Nighttime Heat Exposures on Anxiety: A Randomized Crossover Trial

Abstract Although heat exposure has been linked to adverse mental health outcomes, little is known about the different psychological effects of daytime and nighttime heat exposure. This study employed a randomized controlled crossover trial design. Between July and August 2025, 4...

Association of depressive symptoms with retinal layer thickness: insights from the population-based Beijing eye study 2011

The aim of this study is to investigate the association between depressive symptoms and retinal layer thickness in a population-based adult Chinese cohort. This population-based, cross-sectional study included 2127 eyes of 2127 participants of Beijing Eye Study 2011, free of any...

Dynamics of the Asian Summer Monsoon Anticyclone: insights from potential vorticity tendency diagnostics

The Asian Summer Monsoon Anticyclone (ASMA), the dominant circulation in the upper troposphere and lower stratosphere (UTLS) during the boreal summer, undergoes pronounced spatio-temporal variability. While the climatological mean state of the ASMA is well documented, the mechani...

Free Radical Multiphase Chemistry on Tropospheric Photoreactive Particles

Abstract Gas-phase and multiphase reactions of free radicals play pivotal roles in tropospheric chemistry. Recent studies indicate that photoinduced multiphase reactions serve as a potential source of free radicals rather than a traditional sink. To accurately evaluate their envi...

Shaping the future of transit: Innovations and prospects of intelligent connected bus systems

Abstract As urbanization progresses, traffic congestion has become an increasingly severe issue confronting metropolitan areas worldwide. Intelligent connected bus systems (ICBS) emerge as a transformative solution to address this challenge. This review synthesizes ICBS as a laye...

Molecular Bridge Engineering at the Anode/Electrolyte Interface: Synergistic MPS/ZnO Hybrid Corrosion Inhibition for High-Utilization Alkaline Al-H2O Batteries

Abstract Aluminum-water (Al-H2O) batteries, enabling on-demand high-purity hydrogen production and simultaneous power output, hold great promise for hydrogen energy and electrochemical energy storage applications. However, severe self-corrosion of aluminum anode and parasitic hyd...

Infrastructure-Assisted Cooperative Decision Model With Priority Awareness at Unsignalized Intersections

Abstract Unsignalized intersections pose a significant challenge for multi-vehicle cooperative decision-making, where safety and efficiency must be ensured simultaneously under dynamic traffic conditions. To address this challenge, this study proposes a Vehicle-to-Infrastructure...

Trust in emergency response: The impact of time pressure and artificial intelligence rank

As emergency response environments become more complex and uncertain, artificial intelligence (AI) has the potential to support emergency commanders' decision-making, yet there remains limited understanding of how emergency commanders use AI in real emergency contexts. Sixty-four...

Human Subcutaneous Adipose Transcriptomes Link Mitochondrial Transcription to Metabolic Heterogeneity in Obesity

Background: Metabolically healthy obesity and metabolically unhealthy obesity may occupy different positions along a continuum of adipose-tissue dysfunction, but stable molecular distinctions remain uncertain. Methods: We integrated three public human subcutaneous-adipose-tissue...

Quantum Laurent Positivity for Mutation-Acyclic Cluster Algebras

We prove quantum Laurent positivity for mutation-acyclic skew-symmetrizable cluster algebras of arbitrary finite rank. The main results of this paper were generated using GPT-6-Astra and the Danus system. The author supplied relevant references, checked the manuscript, and revise...

Catalytic Enantioselective Remote Transannular Desymmetrization of Calix[4]Arenes to Inherently Chiral Double‐Macrocycles

ABSTRACT There has been a recent surge in research aimed at synthesizing inherently chiral macrocycles that lack point, axial, planar, or helical chirality. To overcome the structural limitations of existing inherently chiral macrocyclic systems, which often suffer from facile ra...

Potential‐Programmed Mo Dissolution–Induced Reconstruction of Commercial NiMo Foam for High‐Current Alkaline Hydrogen Evolution

ABSTRACT Hydrogen production via water electrolysis is a sustainable pathway, yet its widespread application is hindered by high energy consumption. Therefore, the development of efficient non‐precious‐metal catalysts for the hydrogen evolution reaction (HER) is of great importan...

Modeling and quantification of beam steering uncertainties in high-pressure laser absorption spectroscopy of non-uniform physical fields

Beam steering induced by refractive index gradients poses a significant challenge for laser absorption spectroscopy in high-pressure, non-uniform combustion environments. This work establishes a physics-based framework to model and quantify beam steering effects on path-integrate...

Data-driven identification of economic drivers and regional disparities of ecological resilience in china’s urban agglomerations: an explainable deep learning framework
