The nitrogen vacancy (NV) center in diamond exhibits spin-dependent fluorescence and long spin coherence times under ambient conditions, enabling applications in quantum information processing and sensing 1, 2. NV centers near the surface can have strong interactions with external materials and spins, enabling new forms of nanoscale spectroscopy 3–6. However, NV spin coherence degrades within 100 nanometers of the surface, suggesting that diamond surfaces are plagued with ubiquitous defects 7–10. Prior work on characterizing near-surface noise has primarily relied on using NV centers themselves as probes 7–12;while this has the advantage of exquisite sensitivity, it provides only indirect information about the origin of the noise. Here we demonstrate that surface spectroscopy methods and single spin measurements can be used as complementary diagnostics to understand sources of noise. We find that surface morphology is crucial for realizing reproducible chemical termination, and use these insights to achieve a highly ordered, oxygen-terminated surface with suppressed noise. We observe NV centers within 10 nm of the surface with coherence times extended by an order of magnitude. Copyright © 2018, The Authors. All rights reserved.

To provide higher data rates, as well as better coverage, cost efficiency, security, adaptability, and scalability, the 5G and beyond 5G networks are developed with various artificial intelligence techniques. In this two-part paper, we investigate the application of artificial intelligence (AI) and in particular machine learning (ML) to the study of wireless propagation channels. It firstly provides a comprehensive overview of ML for channel characterization and ML-based antenna-channel optimization in this first part, and then it gives a state-of-the-art literature review of channel scenario identification and channel modeling in Part II. Fundamental results and key concepts of ML for communication networks are presented, and widely used ML methods for channel data processing, propagation channel estimation, and characterization are analyzed and compared. A discussion of challenges and future research directions for ML-enabled next generation networks of the topics covered in this part rounds off the paper. © 2021, CC BY-NC-ND.

Chronic care manages long-term, progressive conditions, while acute care addresses short-term conditions. Chronic conditions increasingly strain health systems, which are often unprepared for these demands. This study examines the burden of conditions requiring acute versus chronic care, including sequelae. Conditions and sequelae from the Global Burden of Diseases Study 2019 were classified into acute or chronic care categories. Data were analysed by age, sex, and socio-demographic index, presenting total numbers and contributions to burden metrics such as Disability-Adjusted Life Years (DALYs), Years Lived with Disability (YLD), and Years of Life Lost (YLL). Approximately 68% of DALYs were attributed to chronic care, while 27% were due to acute care. Chronic care needs increased with age, representing 86% of YLDs and 71% of YLLs, and accounting for 93% of YLDs from sequelae. These findings highlight that chronic care needs far exceed acute care needs globally, necessitating health systems to adapt accordingly. © 2025. The Author(s).

Microseismic source location using a 3D velocity model: From the ray tracing method to waveform inversion

引用

IOP Conference Series: Earth and Environmental Science 2021年第4期861卷

作者： Xueyi Shang Runxue Miao Yi Wang State Key Laboratory of Coal Mine Disaster Dynamics and Control School of Resources and Safety Engineering Chongqing University Chongqing 400044 China State Key Laboratory of Geodesy and Earth's Dynamics Innovation Academy for Precision Measurement Science and Technology Chinese Academy of Sciences Wuhan 430077 China

Microseismic (MS) source location is important in MS monitoring, providing the basis for determining fracture zones and calculating seismic source parameters (e.g., event magnitude and focal mechanisms). To date, homogenous, 1D, and simple 3D velocity models have been adopted in MS source location. However, a mine is usually characterized by a strong velocity heterogeneity due to engineering geology, 3D geostress, and excavation. In this work, we adopted a travel-time tomography-based high-resolution 3D velocity model and then applied 3D ray tracing based on the shooting method, 3D Gaussian beam-based reverse-time method, and waveform inversion method to MS source location. A semiautomatic waveform-cut method based on the cross-correlation (WCC) technique was developed for a quick, robust, and precise determination of the direct P-phase relative delay times. Additionally, the spectral element method for wavefield modeling, multiscale grid (coarse grid + fine grid) 3D waveform inversion, and L-BGFS iterative method were applied in the waveform inversion. Our results show that the commonly used ray tracing method may be affected by multiray path effects and waveform focusing/defocusing during wavefield propagation, whereas the Gaussian beam method has a frequency-dependent width, and the waveform inversion method has a broader frequency width, which can effectively overcome the issues of ray tracing. The average location errors of eight blasting events obtained using the 3D ray tracing, Gaussian beam, and waveform inversion methods are 26.2, 17.0, and 17.6 m, respectively, which are smaller than those of previous researches obtained using the homogenous-velocity model (average location error > 40 m). In conclusion, the high resolution of the location methods based on 3D velocity models can provide an effective approach to improve the MS source location accuracy and exhibit broad application potential.

With the development of new technologies for smart grid construction, the smart grid is gradually developing. Smart grid construction is an important field of next generation information technology, and its value and significance have been widely recognized. Smart grid construction not only provides development opportunities, but also brings great challenges. Security and privacy have become serious problems in the development of smart grid. Based on this, this paper discusses the system structure of the block chain, and puts forward the security diagnosis scheme of the smart grid according to the existing problems in the smart grid. Based on the theoretical basis of smart grid big data technology, this paper combines the grid data encryption process with the privacy protection process under the premise of protecting privacy and security, and develops the latest network security protocol. Then use block chain distributed storage to reduce the connection protection process in privacy, and use multi-level encryption. The experimental results show that the technology can improve the rate of sensitive data hiding and has good anti-cracking ability, which provides a theoretical reference for the construction of enterprise power grid.
