How circular economy reshapes aluminum demand and carbon emissions in the Chinese automotive sector

Vehicle electrification and lightweighting deepen the automotive sector’s reliance on wrought aluminum alloys. With limited recycling capacity, wrought aluminum supply relies heavily on primary aluminum production, leading to higher embodied carbon emissions. This study investiga...

Host-mediated insecticide sequestration in target-site-resistant pests impacts parasitoid fitness and evolution

Insecticide resistance poses a major challenge to global pest management, yet its cascading effects on ecological networks remain poorly understood. Here, we show that target-site-resistant herbivorous insects can accumulate unmetabolized insecticides and inadvertently function a...

Growth‐Compatible Low‐Interference Flexible Sensors for Long‐Term In Situ Monitoring of Plant Growth

ABSTRACT Continuous in situ plant growth monitoring is essential for precision agriculture. Flexible electronics offer a non‐invasive solution, yet balancing measurement sensitivity with minimal biological interference remains a key design challenge. Here we report two growth‐com...

Missed Opportunities for Stroke Prevention in Patients With Hypertension: A Retrospective Case–Control Study

BACKGROUND: Hypertension is the leading modifiable risk factor for ischemic stroke, yet the adequacy of preventative hypertension care in routine clinical practice remains suboptimal, potentially representing missed opportunities for stroke prevention. We evaluated the associatio...

Interventional strategies for inferior phrenic artery management in yttrium‑90 selective internal radiation therapy for hepatocellular carcinoma: A single‑center retrospective study

Extrahepatic collateral supply from the inferior phrenic artery (IPA) is frequently observed in patients with hepatocellular carcinoma (HCC) undergoing yttrium-90 selective internal radiation therapy ( 90 Y-SIRT). Currently, no standardized IPA management algorithm has been estab...

Dipole–dipole interaction facilitates anion-rich solvation structures in polymer electrolytes for solid-state lithium metal batteries

Polymer electrolytes are vital for safe and high-energy–density lithium metal batteries but face challenges from interfacial instability and Li dendrites. Here, we report a molecular design exploiting dipole–dipole interactions to tailor Li + solvation structures and interfacial...

Semi-Supervised Gearbox Anomaly Detection Under Variable Operating Conditions

Feature distributions shift under variable-speed gearbox operation, which can cause a model trained only on healthy samples to misclassify normal operating changes as anomalies. A semi-supervised anomaly detection method is proposed in this study. Using healthy data, the method f...

Geopolitical tensions with the US accelerate Chinese firms’ leveraging of science

US restrictions on access to technologies have led Chinese firms to intensify and broaden the scope of their scientific knowledge sourcing

Enhanced nocturnal N 2 O 5 -ClNO 2 chemistry in Delhi under reduced NO conditions

Nitryl chloride (ClNO 2 ) is an important Cl⚫ precursor, originating from the heterogeneous reactions of dinitrogen pentoxide (N 2 O 5 ) on chloride-containing particles. This N 2 O 5 -ClNO 2 chemical process plays critical roles in chloride activation, nitrate formation, and th...

CuI / CuO Heterointerface Enables Selective Aqueous Electrosynthesis of 2‐Iodoxybenzoic Acid

Comprehensive Summary Aqueous electrosynthesis of hypervalent iodine(V) oxidants provides a sustainable and oxidant‐free alternative to conventional chemical synthesis, but the electrooxidation of 2‐iodobenzoic acid (IBA) to 2‐iodoxybenzoic acid (IBX) is limited by sluggish react...

Photoluminescent amorphous silicon microspheres with intrinsic whispering-gallery-mode coupling and waveguide integration

Abstract On-chip silicon light sources are highly desirable for integrated photonics but remain challenging due to silicon’s indirect bandgap and low radiative efficiency. Amorphous silicon supports photoluminescence via band-tail states, yet lacks scalable cavity platforms for e...

Algorithmic seeing and human-machine co-interpretation in digital art history

This study examines how convolutional neural networks produce a conditioned mode of algorithmic seeing in art-image analysis. Using an artist attribution task based on more than 7000 paintings, it analyses training dynamics, misclassification patterns, and interpretability output...

Electron delocalization-driven high dielectric electrolyte for solid-state lithium metal batteries

Solid-state polymer electrolytes hold significant promise for solid-state lithium metal batteries but have been severely plagued by how to simultaneously achieve high ionic conductivity and construct a stable interphase. Here, we propose an electron delocalization engineering str...

General heat release rate surrogates for NH3/H2/N2 and H2 flames using Raman/Rayleigh/LIF accessible species

Accurate estimation of the heat-release rate (HRR) is essential for understanding and controlling ammonia–hydrogen combustion, yet conventional experimental surrogates are strongly dependent on operating conditions and typically rely on radicals measured by laser-induced fluoresc...

Supercritical autoignition of methane in an ultra-high-pressure rapid compression machine at up to 160 bar: real-fluid effects and two-stage ignition behavior

Although methane autoignition under ultra-high-pressure and supercritical conditions is highly relevant to advanced high-pressure combustion systems, such conditions have rarely been studied in RCMs. In this work, supercritical methane ignition is investigated in a newly establis...

Optically Selected Superthin Galaxies Remain Thin in the Near-infrared

Abstract We investigate whether galaxies identified as superthin in optical images remain superthin in the near-infrared (NIR), and how their extreme disk morphology is related to environment. From a nearby volume-limited sample, we select 210 superthin galaxies using two-dimensi...

Net carbon losses in Central African forests revealed by high-resolution biomass change maps

Dense humid forests in Central Africa hold vast biomass carbon stocks but are increasingly affected by small-scale disturbances that are difficult to detect with current satellite observations. Here, we generate 10 m canopy height maps for 2019–2022 using deep learning with space...

Accurate single-step error estimation and universality for second-order implicit and explicit time integration algorithms in computational mechanics

This paper presents a unified single-step a posteriori error estimator for a broad class of second-order implicit and explicit time integration schemes used in solid mechanics, structural dynamics, fluid–structure interaction, and hyperbolic heat transfer and the like. The estima...

The cubic moment of central L -values in the weight aspect

Motivated by the list of problems for moments of L -functions due to Hamieh et al. [7], we prove an asymptotic formula for the cubic moment of central L -values associated to holomorphic cusp forms of level one, where the weights k lie in a short interval K - Δ < k < K + Δ with K...

Historical Trade Liberalization and Modern Innovation: Evidence From China's Treaty Ports

ABSTRACT Does trade liberalization exert a long‐lasting influence on innovation? To answer this question, we exploit a unique historical setting: China's forced market opening through the treaty port system from 1842 to 1943, combined with comprehensive firm‐level innovation data...
