Mechanism of the Salt Anions Impacting on the Interface Chemistry of the Anode During High‐Temperature Calendar Ageing

ABSTRACT The calendar ageing has long plagued practical realization of long‐life lithium‐ion batteries (LIBs), and the interfacial ageing significantly affects electrochemical performances compared with bulk electrolyte hydrolysis, while its mechanism remains insufficiently eluci...

Stable Quantum Dot Light‐Emitting Diodes Compatible With Household Alternating Current Electricity

ABSTRACT Like other p‐n junction devices, quantum dot light‐emitting diodes (QLEDs) can only operate with direct current (DC), which is incompatible with household 220 V/50 Hz alternating current (AC), and accelerates device degradation due to constant charge injection and accumu...

Probing dark matter and phantom field effects on neutrino oscillations around black holes

Abstract This study investigates how dark matter in the background of the phantom field (DMPF) near a black hole influences neutrino flavor oscillations using a two-flavor model. It is found that gravitational effects are cancelled for radially moving neutrinos, causing the oscil...

A 3D VTI Factored Eikonal Solver Using a Six‐Tetrahedron Pyramidal Stencil

ABSTRACT Accurate traveltime computation for the eikonal equation is essential in seismic applications such as tomography and migration. The fast sweeping method is widely used because of its unconditional stability and computational efficiency. We develop a three‐dimensional fas...

Measurement report: Quantifying the trade-off between station number and spatial layout in sparse GNSS networks for calibrating all-weather FY-4A precipitable water vapor

Abstract. Integrating satellite-derived precipitable water vapor (PWV) provides data with high spatiotemporal resolution, which is crucial for monitoring and forecasting extreme weather. However, current fusion and calibration methods typically relies on dense GNSS networks, hind...

An interpretable learning framework for exploring superelastic degradation of NiTi shape memory alloys using multimodal data

Abstract Superelastic degradation (SED), a progressive loss of functionality in NiTi shape memory alloys under cyclic loading, remains challenging to characterize precisely, thereby constraining their engineering applications and broader adoption. In this study, an interpretable...

Weakening Local Chemical Bonds for Enhanced Thermoelectric Performance in YbMg 2 Sb 2 Zintl Compounds

ABSTRACT Alloying is a well‐established strategy for reducing lattice thermal conductivity ( κ L ) and enhancing thermoelectric performance of materials, typically explained by the Klemens model, which describes the point‐defect phonon scattering via mass and size contrasts. Yet,...

Longitudinal plasma phosphorylated tau217 classification and the association with Alzheimer's disease progression

Abstract INTRODUCTION Longitudinal diagnostic and prognostic validity of plasma phosphorylated tau217 (p‐tau217) in Alzheimer's disease (AD) remains uncertain. METHODS In this multi‐cohort study of 2117 individuals, we established baseline plasma p‐tau217 thresholds for amyloid‐β...

Classifications of Substorms With MLT Patterns of SMU‐SML Indices Based on Convection Properties

Abstract During substorms, magnetospheric convection and magnetotail current sheet disturbances are two critical processes, both driving ionospheric electrojets. Dusk‐side SMU and dawn‐side SML (SuperMAG Electrojet indices) enhancements reflect two‐cell convection. Using this rel...

The Effects and Mechanisms of Thermal Oxygen Aging on Trap Characteristics and Electrical Performance of Functional Group‐Grafted Materials for HVDC Cable Insulation

ABSTRACT In this study, N‐allylaniline (NA), a functional monomer possessing both deep trap‐inducing and antioxidant capabilities, was grafted onto cross‐linked polyethylene (XLPE) to prepare XLPE‐g‐NA. Both XLPE and XLPE‐g‐NA were subjected to thermo‐oxidative aging, and their p...

Adaptable weaving origami

As intelligence continues to deepen in engineering fields, adaptable shape-morphing structures face increasing demands for multifunctionality and reconfigurability. Origami has been widely explored in deployable structures, mechanical computing, metamaterials, and metamorphic rob...

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...

Mo equivalent guided microstructural regulation and strength-toughness synergy of Fe-doped near β titanium alloy

The intrinsic strength-toughness trade-off, coupled with an inadequate understanding of microstructure regulation, restricts the further development of as-cast near β titanium (Ti) alloys with ultra-high strength and toughness. In this work, a series of Ti-7Mo-4Al-4Zr-3Nb-2Cr- x...

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...

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...

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...
