High gain Ga2O3/GaN avalanche photodetector with separated absorption and multiplication structure

Teng Jiao, Wei Chen, Zhaohui Zhang, Zhe Wang et autres

The β-Ga2O3/p-GaN heterojunction avalanche photodetector (APD) with separated absorption and multiplication (SAM) structure was fabricated by metal–organic chemical vapor deposition. Through x-ray diffraction and scanning electron microscopy characterization, the Ga2O3 films exhibit relatively high crystalline quality. Through reasonable design of the electron …

Exploring potential resting-state EEG biomarkers of obsessive-compulsive disorder based on explainable machine learning analysis of independent training and test samples

Zongya Zhao, Junming Wang, Yanxiang Niu, Mengyue Qiu et autres

BACKGROUND: At present, the clinical diagnosis of obsessive-compulsive disorder (OCD) is primarily based on interviews with patients by experienced psychiatrists, which is inherently limited by its subjectivity. Therefore, there is a pressing clinical need to identify objective biomarkers of OCD. Although the …

Millimeter-Scale Spatial Resolution Raman Sensing System Enabled by Bidirectional Fiber Laser

Pingan Liu, Zhaohui Zhang, Liguo Zhu

We report a high-spatial-resolution distributed temperature sensing system using an asynchronous mode-locked fiber laser. It employs two picosecond pulse trains with a 6,100 Hz repetition rate difference. One is amplified as pump light (~46 ps) to excite Raman scattering, while the other …

A capacitor divider with bandwidth over 10 GHz

Fan Guo, Bing Wei, Le Xu, Chongbiao Luan et autres

The characteristics of capacitor dividers of disk and coaxial configurations are investigated. The amplitude-frequency response properties of two disk capacitor dividers obtained during the experiments indicate that the upper-limited response frequency of the disk sensor could be improved by decreasing its diameter. …

LLM-Assisted Non-Dominated Sorting Genetic Algorithm for Solving Distributed Heterogeneous No-Wait Permutation Flowshop Scheduling

Zhaohui Zhang, Hong Zhao, Wanqiu Zhao, Xu Bian et autres

In distributed manufacturing systems, minimizing completion time and improving resource utilization are critical for enhancing operational efficiency. Conventional scheduling models for centralized flowshops struggle to capture the complexity of distributed heterogeneous systems, while existing studies often overlook the combined challenges of heterogeneous …

Effect of different extraction methods on the structure and anti-aging skin activity of Ulva pertusa Kjellm polysaccharide

Lu Zhe Sun, Jiandong Li, Zhaopeng Shen, Guoxia Li et autres

This study aimed to investigate the differences in structure and activity of polysaccharides from Ulva pertusa Kjellm extracted by different methods, including hot water extraction (HWE)-HUP, microwave-assisted extraction (MAE)-MUP and ultrasonic-assisted extraction (UAE)-UUP. The polysaccharide extraction rates for HWE, MAE, and UAE …
