Alternating-chiral charge density waves and associated spin polarization in monolayered NbTe2

Intertwining of different quantum degrees of freedom manifests exotic quantum phenomena in many-body systems, especially in reduced dimensionality. Here we show that monolayered NbTe2 serves as a promising platform where lattice, charge, and spin degrees of freedom manifest coope...

Urban water system resilience and risk assessment in a typical arid industrial city: a case study of Karamay

This study develops a multi-dimensional framework to assess urban water resource resilience and risk in Karamay, a typical resource-based industrial city in arid northwest China. By integrating long-term data on water supply and demand, meteorological and hydrological conditions,...

Analysis of the evolution of South-South Cooperation from the perspective of Southern Identity

Abstract We propose the term “Southern Identity” to encompass the concepts of the Third World, developing countries and the Global South, establishing a logical counterpart to Western Identity. The concepts of the Third World, developing countries and the Global South arose withi...

CritiFlip: an efficient bit-flip attack based on critical weight identification

Abstract Recent studies have demonstrated that deep neural networks (DNNs) are highly vulnerable to bit-flip attacks (BFAs), where modifying only a few bits in memory can severely degrade model performance. However, existing BFA techniques typically rely on exhaustive searches ov...

Research on an Innovation Opportunity Identification Method Based on Link Prediction in Heterogeneous Networks

A large number of potential knowledge associations in scientific and technological innovation activities have not yet become explicit. How to identify potential valuable innovation opportunity clues from complex knowledge structures has therefore become an important issue in inte...

CO2 laser processing of fused silica: a review of mechanisms, defect control and functionalization

Fused silica optics are critical components in inertial confinement fusion facilities, where they are exposed to intense ultraviolet laser radiation. However, processing induced subsurface defects serve as laser damage precursors, severely degrading the laser-induced damage thres...

An orthogonal transcription system enables high-efficiency rescue of measles virus-based vaccine vectors against multiple pathogens

Recombinant measles virus (rMeV) vectors are promising platforms for vaccine development against emerging infectious diseases due to their safety, stability, and potent immunogenicity. However, conventional rMeV rescue systems frequently exhibit low efficiency, thereby constraini...

Hybrid Physics-Data-Driven Framework for Blind Acoustic Impedance Inversion

Abstract Conventional acoustic impedance inversion methods have long faced technical bottlenecks such as inaccurate wavelet estimation and strong dependence on initial models. Although existing deep learning approaches can partially alleviate these problems, they often compromise...

Indicator system for regional public health emergency response capacity based on ternary space theory: construction and empirical study in China

Abstract Background Establishing a comprehensive national public health emergency management system is essential for ensuring population health. However, pronounced disparities in economic development and healthcare resources among China’s provinces have led to heterogeneous publ...

Multi-omics and cultivation reveal laminarin-degrading PVC bacteria in the deep sea

The deep sea is home to a vast and largely unexplored microbial biosphere, along with large amounts of complex organic matter (COM). However, the functional capacity of the deep-sea microbiome to metabolize organic matter across diverse regions remains poorly understood. Here, we...
