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...

All-Optically Controlled Memristive Reservoir Computing Capable of Bipolar and Parallel Coding

Physical reservoir computing (RC) utilizes intrinsic dynamics of physical systems for efficient data processing. Emerging optoelectronic RC platforms merge the benefits of electronic and photonic computation. However, conventional designs are constrained by the unipolar photoresp...

65 TOPS optoelectronic multi-core computing unlocking multi-feature fusion enhancement

The rapid progress of artificial intelligence demands scalable, energy-efficient hardware with massive parallelism and high throughput. Although optical computing offers a promising post-Moore solution, current implementations face speed limitations and multi-core integration cha...

X‑ray computed tomography‑based experimental investigation of CO₂ miscible zone formation mechanisms and degree of miscibility

Carbon dioxide capture, utilization, and storage–enhanced oil recovery (CCUS–EOR) depends on the progressive development of CO₂–oil miscibility, yet the pressure-controlled transition from interfacial mass transfer to porous-media miscible-zone propagation remains difficult to qu...

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...

Optimizing Tribological Performances and Corrosion Resistance of (TiNbCrZrMo)N x High‐Entropy Nitride Coatings via Substrate Bias Modulation

To meet the corrosion protection and lubrication requirements of mechanical transmission components in marine environments, this paper is dedicated to designing a (TiNbCrZrMo)N x high‐entropy nitride (HEN) coating by magnetron sputtering deposition and optimizing its tribological...
