PAPEL: A Collaborative System for Parental Guidance during Preschool Play-Based English Learning

Play-based parent-child interaction offers preschoolers rich opportunities for everyday foreign language learning, yet many parents struggle to turn open-ended play into effective English-as-a-Foreign-Language (EFL) learning experiences at home. To explore how AI might support th...

Enhanced Detection of Electrolyte Microleaks by Reduced-Pressure Ion Mobility Spectrometry

Abstract Electrolyte leakage is an early indicator of sealing failure and a potential safety risk in lithium-ion batteries, but vapor release from microscopic defects remains difficult to detect because the amount of analyte released is small, transport to the detector is ineffic...

Stress-engineered 0.34 nm graphene memristors for low-power probabilistic computing

Memristors are promising for neuromorphic computing electronics, yet scaling is hindered by the difficulty of fabricating ordered nanoscale electrodes. Here, we report an angstrom-scale graphene-edge memristor with a geometrically defined 0.34 × 0.34 nm2 crossed-electrode area. K...

The Boosted Research of Activating the Chinese Three Provinces GDP Status on Sustainability I

An embodied artificial intelligence as an important robot product has felt concept and behavior based on the physical body through connecting with environmental communication so as to acquire information̖ understanding problem and make decision for the sake of realizing behavior...

Experimental and theoretical study on shear performance of T-shaped and bulb flat shear connectors in composite structures

This study investigates the mechanical performance and theoretical design methods of T-shaped and bulb flat shear connectors in large-scale steel-concrete composite structures. The full-scale push-out test were conducted, including 9 groups of T-shaped and 6 groups of bulb flat s...

Numerical investigation of seismic dynamic response and liquefaction characteristics of suction bucket foundation

As offshore wind development expands into regions where earthquake induced seabed liquefaction may occur, the seismic performance of offshore wind turbine foundations requires careful assessment. In this paper, based on centrifugal test, the OpenSees finite element numerical mode...

"Re-Tell the Fortune so I Can Believe It": How Chinese User Communities Engage with and Interpret GenAI-based Fortune-Telling

People traditionally divine the future by interpreting natural phenomena as oracular signals, especially in societies adhering to traditional beliefs like China. With the advent of Generative AI (GenAI), people gain access to new ways of probing digital oracles for predicting the...

Three-dimensional laser micro/nano printing for optical computing

Abstract With the rapid growth of data-intensive computing, optical computing has become an important method for information processing with high bandwidth, low latency, and parallel operation. Early implementations were bench-top free-space systems, in which lenses, masks, and h...

Twitch Third-Party Developers’ Support Seeking and Provision Practices on Discord

Third-party developers (TPDs) often turn to online communities for support when they can’t get immediate responses from the platform. Twitch, as a leading live streaming platform, attracted many TPDs and formed an online support community on Discord. This study explores TPDs’ sup...

Edge-Affinity-Directed Selective Pore-Mouth Sealing in Coal-Derived Hard Carbon for Stable and High-Capacity Sodium Storage

Abstract Sodium-ion batteries are attractive for large-scale energy storage, but the limited capacity of hard-carbon anodes constrains practical energy density. Increasing porosity can boost capacity, but typically enlarges the electrolyte-accessible surface, lowers the initial C...

Sustainability assessment of China's nitrogen-phosphorus cycling system under future carbon neutrality transition scenarios

Achieving sustainable management of the nitrogen–phosphorus (N–P) cycling system is essential for advancing multiple United Nations Sustainable Development Goals, yet its long-term sustainability under carbon neutrality transition pathways remains insufficiently understood. This...

Fragility of Magic State Distillation under Imperfect Measurements

Magic state distillation (MSD) is the leading approach for producing the non-Clifford resources required for universal fault-tolerant quantum computation. Most prior analyses of MSD assume ideal projective stabilizer measurements, but this assumption becomes questionable on near-...

Triple‐Phase Synergistic Bulk‐Surface Engineering Enables High‐Rate and Long‐Cycling P2/O3‐Based Cathode for Na‐Ion Batteries

ABSTRACT Layered oxide cathodes hold great promise for Na‐ion batteries (NIBs) but suffer from rapid performance degradation under high voltage, primarily arising from severe lattice strain, transition metal migration, and detrimental surface degradation. Here, we report a triple...

Leveraging Metamaterial‐Inspired Wireless Resonator for Reliable Quantitative MRI at 1.5T: Linearity, Bias, and Repeatability Assessment

ABSTRACT The accuracy of quantitative magnetic resonance imaging (qMRI) largely depends on the image signal‐to‐noise ratio (SNR). In recent years, studies on metamaterials in MRI have shown that they can significantly improve image quality through weak coupling with the body coil...

Optimal Tariffs with Partial Cross-Ownership in a Vertical Market: Uniform Versus Discriminatory Tariffs

Abstract This paper investigates the welfare impact of discriminatory tariffs and uniform tariffs in the presence of vertical cross-ownership. We develop a four-country three-firm model, where the upstream firm and two downstream firms with asymmetry are located in different coun...

Development of proteome-derived cyclic peptide libraries via ortho-phthalaldehyde-assisted cyclization

Cyclic peptides possess unique structural features and binding capabilities that make them attractive scaffolds for molecular recognition. However, strategies for generating functionally diverse libraries directly from natural proteomes remain comparatively underdeveloped. Here,...

Shape effects in granular flow down a rough incline: Understanding the role of particle flatness and elongation

Dense granular flow on rough inclines provides a canonical setting for investigating gravity-driven mass movements, yet the role of particle shape remains insufficiently understood. Here we use discrete element method simulations to examine how particle flatness modifies inclined...

Reliability-Aware Dual-Stream Self-Training for Semi-Supervised Semantic Segmentation of High-Resolution Remote Sensing Imagery

Semantic segmentation of high-resolution remote sensing imagery remains constrained by the high cost of pixel-level annotation. Semi-supervised learning can reduce this dependence by exploiting unlabeled images, but improving pseudo-label reliability often comes at the cost of re...

Effects of suspension training and bodyweight resistance training on neuromuscular power, sprint, and agility performance in untrained male adolescents: a three-arm randomized controlled trial

This study compared suspension training (ST) and bodyweight resistance training (RT) with a control condition (CON) for physical performance in untrained male adolescents. Seventy-two participants (age 14.74 ± 0.32 years) were randomized equally to ST, RT, or CON. One participant...
