Full-waveform Light Detection and Ranging (FW-LiDAR) systems emit laser pulses to illuminate targets and capture the reflected pulse's temporal distribution, creating a modulated echo waveform. The echo waveform's properties, such as peak intensity, pulse width, and extent, provide FW-LiDAR with the capability to detail target properties, from structural to biophysical and biochemical characteristics. Despite various methods for analyzing FW-LiDAR data and extracting target properties, a comprehensive review of the current state and future development of target information retrieval using FW-LiDAR is seldom seen. This paper focusing on background, typical application, and limitation of current data analysis method in FW-LiDAR domain. Owing to that a quantitative and concise relationship between the properties of targets and the features of modulated echo waveform has not been evaluated, the general data processing method in FW-LiDAR is still lacking. The current methods can be roughly classified into three categories. The first is the empirical and phenomenological methods. It is majorly the waveform decomposition and deconvolution methods, including Gaussian, generalized Gaussian, log normal Gaussian, Burr decomposition methods, and Richardson-Lucy, Gold, and Blind deconvolution methods. The waveform metrics description parameters following the decomposition include height metrics, and energy metrics. The advantage of this method is facile, while the limitation is that the correspondence between the decomposed or deconvoluted waveform metrics and the properties of targets has also not been established. The second is the model inversion method, including the look-up table method, the iterative numeric optimization method, and the gap theory to extract the target information. This method compares the echo waveform simulated using computing model with the measured. When the waveforms agree excellently, the properties of targets in the simulation approaches the actual.

Integrated electro-optic modulators with large bandwidth, high linearity and low driving voltage are key building blocks for integrated microwave photonic (IMWP) links to transmit broadband signals with high fidelity. In this work, thin-film lithium niobate electro-optic modulator consisting of a thermo-optic reconfigurable coupler and dual-parallel Mach-Zehnder modulation scheme is proposed and demonstrated to achieve spurious-free dynamic range of 112.87/107.71 dB·Hz2/3 at 1/10 GHz while keeping large bandwidth (>67 GHz) and low half-wave voltage (2.7 V) simultaneously. The demonstration of this device paves a new route for high-performance electro-optic modulators in future functional IMWP systems. © 2025 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

A GNN-Guided Variable Selection Approach for Efficient Derivation of the Optimal Solution in Unit Commitment

IEEE Transactions on Power Systems 2025年

作者： Wei, Lishen Ai, Xiaomeng Fang, Jiakun Cui, Shichang Liao, Shiwu Wen, Jinyu Huazhong University of Science and Technology State Key Laboratory of Advanced Electromagnetic Engineering and Technology School of Electrical and Electronic Engineering Wuhan430074 China TODE Co. Ltd. Nanjing210046 China

The growing scale of the power system has intensified the demand for computational efficiency in unit commitment (UC). This paper introduces a novel approach that addresses this issue by adopting graph neural networks (GNN) into the Branch and Bound (B&B), integrating the characteristics of variable selection (VS) within UC problems. Our method focuses on efficiently obtaining optimal solutions using the GNNguided VS approach. Specifically, we investigate the characteristics of the high-quality but time-consuming VS heuristic when solving UC problems. Then, the GNN incorporates these characteristics to make highquality VS decisions accurately and quickly. In the implementation, the UC model is solved using a highquality but time-consuming VS heuristic to collect training data. These data are employed to train the GNN model with designed label-smooth and depthadaptive mechanisms, which exploit these characteristics in UC problems for acceleration. To evaluate the effectiveness, we conduct various experiments on the IEEE118, RTS-GMLC, and a real-world provincial system in China. The overall performance demonstrates significant improvements (4.6x, 1.5x, and 1.8x, respectively) in computational efficiency. The comparison experiments show that the proposed mechanisms contribute to enhanced learning performance and, thus, further UC acceleration. Moreover, our approach exhibits promising generalization capabilities. © 1969-2012 IEEE.

Erbium oxide (Er2O3) films with excellent thermal and optical performance are essential for application as heat-resistant and anti-reflective (AR) materials in chemical vapor deposition (CVD) diamond infrared windows. In this study, the thermal stability of Er2O3 AR films was investigated by heat treatment. The phase composition, microstructure, thermogravimetric analysis, mechanical properties, and infrared (IR) transmission performances of the Er2O3 AR films were thoroughly investigated. The results show that the cubic (222) plane orientation of the Er2O3 AR films after heat treatment was preferential to that at room temperature. No significant change was observed in the DSC and TG curve at the temperature varied, but the DSC curve of the Er2O3 AR films revealed two distinct stages at 502 °C and 798 °C owing to the formation of Er2O3 (420) and (134) planes. Specifically, the phase structure remained unchanged by high-resolution transmission electron microscope (HRTEM) observation, and the peak at 578.4 cm−1 was the only obvious impurity peak in the Raman spectrum owing to the introduction of the Er–O bond. Additionally, significant shedding of the Er2O3 AR films on the surface of the CVD diamond occurred at high temperatures. The grain size and roughness increased as the temperature increased, adversely affecting the continuous abrasion resistance of the Er2O3 AR films. Moreover, the Er2O3 AR films exhibited outstanding mechanical and optical properties at 800 °C, achieving a depth of only 0.65 μm and a maximum transmittance increased from 65 % of diamond to 76 %. This study provides valuable insights into the thermal stability of the Er2O3 AR films under high temperature application scenarios. © 2025 Elsevier Ltd and Techna Group S.r.l.

To meet the welding requirements of SiCp/6061Al metal-matrix composites (MMCs), this paper proposed an additional ultrasonic treatment (AUT) based on traditional ultrasonic-assisted brazing. The shear strength of SiCp/6061Al MMCs brazed joints was effectively improved by a secondary ultrasonic treatment using Sn-Zn solder. Compared with the conventional ultrasonic treatment (43.84 MPa), the strength of the AUT welded joint was increased by 20 MPa, as high as 64.17 MPa. Moreover, through the analysis of the microstructure and fracture structure, the microstructure formation process of the weld during the AUT was found and expressed. 2025 Published under licence by IOP Publishing Ltd.

The Li-CO2battery has been highly rated as an intriguing technique for balancing the carbon cycle for years, but it is still significantly challenged by the obstacles such as limited reversibility, sluggish kinetics,and poor energy efficiency. Hence, the design and development of advance catalysts that can enhance the kinetics and reversibility of the CO2electrochemical cycling reactions are considered the imperative tasks. Transition metal-based catalysts are widely considered appealing owing to their unfilled dorbitals, rich and adjustable valences, as well as processibility. In this review, the working mechanism and the key issues of the CO2electrochemical cycling reaction are discussed first. Then the strategies for composition and structure design of different type of transition metal-based catalysts are highlighted,including their benefits, limitations, and the ways to implement these strategies. Finally, based on the pioneering research, the perspectives on the challenges and key points for the future development of cathode catalyst are proposed.
