Decoupling Chemo‐Mechanical Failure for Robust Li‐Rich Cathodes

ABSTRACT Despite being renowned for their high specific capacity, Li‐rich Mn‐based layered cathodes (LRMs) are constrained by severe capacity degradation and structural deterioration during cycling. The persistent focus on chemical failure, driven by irreversible anionic redox an...

st2traj: deconvolution-informed trajectory inference for multi-timepoint spatial transcriptomics

MOTIVATION: Multi-timepoint spatial transcriptomics enables study of developmental processes in native tissue context, but cell-state mixtures within spots and lack of direct spatial correspondence across sections complicate trajectory inference and biological interpretation. RES...

CellPos: a multi-task learning framework enabling accurate spatial positioning of single-cell RNA sequencing data

Integrating spatial information at single-cell resolution is essential for understanding tissue architecture, development, and disease. Adding spatial context to the body of existing single-cell RNA sequencing data enhances their interpretability and reuse potential, but inferrin...

Strategic allocation and dynamic rescue for multi-defender stackelberg security games with infectious attacks

Abstract Interconnected systems can suffer infectious attacks, where the compromise of one node exposes neighboring nodes and may trigger cascading loss. Existing Stackelberg and network-defense models usually address only part of this setting: a centralized defender, independent...

Financial aid and students’ academic performance in higher education: evidence from a Chinese university

Financial aid is central to higher education equity, yet its associations with academic outcomes may differ by aid type and students’ behavioural context. Drawing on expectancy-value theory, this study examines how merit-based and repayment-based aid are associated with academic...

Circular-orbit dynamics and QPO constraints in static Einstein–scalar–Gauss–Bonnet black holes

Abstract Einstein–scalar–Gauss–Bonnet (EsGB) gravity provides a physically motivated framework for testing strong-field deviations from the Schwarzschild geometry through scalar hair. We study neutral-particle circular motion and high-frequency quasi-periodic oscillations (HF-QPO...

When do consumers trust AI? The moderating roles of service orientation and social class in human-AI service robot collaboration

As artificial intelligence (AI) becomes increasingly autonomous, understanding how human–robot collaboration affects consumer trust has emerged as a critical challenge in human–AI interaction research. Drawing on service orientation theory and social class theory, this research i...

Compositional architecting by additive manufacturing enables hardenable titanium alloys

Titanium alloys (Ti-alloys) often suffer from limited strain-hardening capacity (typically <250 MPa), hindering broader adoption in demanding structural applications. This study reports a Ti-alloy with ultrahigh strain-hardening capability, enabled by a unique three-dimensional c...

An Optically Transparent Metamaterial Window Based on Metal Meshes With Integrated Absorption and Transmission

ABSTRACT This work presents an absorptive–transmissive integrated metamaterial window using a quartz substrate and micrometer‐scale metallic meshes. The structure employs a three‐layer design comprising a resonant layer, a dielectric spacer, and a frequency‐selective surface. It...

Preparation and Dielectric Properties of Polyethylene Composites Modified by Nano‐ TiO 2 Coated Zeolites With Different Pore Sizes

ABSTRACT Low‐density polyethylene (LDPE) insulation in high‐voltage direct current (HVDC) cables is prone to space charge accumulation and electric field distortion. To address this, we propose a core–shell modification strategy using nano‐TiO 2 ‐coated porous zeolites (4A and Na...
