Nailfold capillaroscopy and deep learning in diabetes 甲襞毛细血管镜检测与深度学习在糖尿病中的应用
Journal of Diabetes, Volume 15, Issue 2, Page 145-151, February 2023., 2023 Highlights Nailfold capillary images were obtained by performing nailfold video capillaroscopy in 120 adult patients with and without diabetes. Over 5000 photographs were analyzed using machine‐learning approaches, and these models were clearly able to distinguish people based on diabetes status.

New Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,

Performance of machine‐learning approach for prediction of pre‐eclampsia in a middle‐income country
Ultrasound in Obstetrics &Gynecology, Volume 63, Issue 3, Page 350-357, March 2024.ABSTRACT Objective Pre‐eclampsia (PE) is a serious complication of pregnancy associated with maternal and fetal morbidity and mortality. As current prediction models have limitations and may not be applicable in resource‐limited settings, we aimed to develop a machine‐learning (ML) algorithm that offers a potential solution for developing accurate and ...

Gaoya dianqi, 2017 为了掌握特高压交流GIS变电站的噪声特性,以1 000 kV特高压芜湖变电站为研究对象,对站内主变压器、高压并联电抗器以及站界噪声声压级进行了测量,分析了站内主要噪声源的频谱分布、噪声水平以及噪声传播与衰减特性。结果表明,主变压器噪声与高压并联电抗器噪声较为接近且以中低频为主,均在70 dB（A）左右。冷却风扇噪声对主变压器噪声影响较大。主变压器与高压并联电抗器噪声传播过程中均存在较为明显的干涉现象,其中以100、200 Hz噪声干涉最为显著。站界噪声受站内声源位置的影响较大,距离噪声源越近 ...

Dianci bileiqi, 2022 特高压变压器中性点经小电抗接地在降低线路单相短路电流的同时，提高了中性点的过电压水平，为中性点配置合适的过电压保护十分重要。本研究运用EMTP对华东某特高压变电站进行等值建模，对变压器中性点串接多个阻值小电抗后限制短路电流能力进行量化分析，从而确定中性点小电抗的最佳取值。根据工程实际，变压器中性点串接小电抗后，在中性点并联氧化锌避雷器和放电间隙可以提供一定的过电压保护。由于避雷器动作后残压过高，会使放电间隙击穿放电，考虑用可控避雷器替代氧化锌避雷器以实现最佳的绝缘配合。
