Long-Term Outcomes of Concurrent Chemoradiotherapy With S-1 in Older Patients With Esophageal Cancer

Yongling Ji, Min Fang, Weiguo Zhu, Yanguang Yang et autres

Importance: Most older patients with esophageal cancer (EC) are unable to complete standard platinum-based concurrent chemoradiotherapy (CCRT) due to reduced organ reserve, comorbidities, and malnutrition. A new treatment option-CCRT with S-1-has been found to have high efficacy and fewer toxic effects for …

Minimal Salt-Assisted Sulfuric Acid Oxidation Roasting for Selective Lithium Extraction from Spent LiFePO 4 Batteries

Yuanda Zheng, Hong Zhang, Feng Luo, Bing Li et autres

Recovering lithium from spent LiFePO 4 batteries presents a significant opportunity to address the issue of lithium scarcity. However, current technology requires many strong oxidants to achieve precise lithium selectivity, which is costly and inevitably causes secondary pollution. In this paper, a …

Distributed Optical Fiber Sensing of Temperature Rise During 110 kV Conductor–Ground Wire Ice-Shedding Discharge

Yanpeng Hao, Zihan Wu, Lei Huang, Yuanda Zheng et autres

Ice-shedding on overhead transmission lines can easily lead to jump discharge and subsequent line tripping, and effective monitoring methods are still lacking. To address this problem, this study proposes a distributed optical fiber sensing approach based on Brillouin optical time-domain reflectometry (BOTDR) …

Electro-Thermal Coupling Calculation in Submarine Cables: A Method Based on Fiber-Optic Temperature Monitoring and Analysis of its Accuracy Determinants

Ji Wu, Hongyi Zhong, Xin Yu, Yanpeng Hao et autres

Monitoring the conductor temperature constitutes a crucial index for assessing the operational health of 500 kV oil-filled submarine cables; however, obtaining direct insitu measurements remains a formidable technical hurdle. Traditional thermal field simulations predominantly derive conductor temperature from ambient environmental conditions, a …

AlGaN/GaN HEMTs on Si by Self-Aligned TaN Contact Ledge for Low-Voltage RF Applications

Weiyuan Wang, Jingxiong Chen, Yuanxi Jiang, Xiao Ma et autres

We propose a self-aligned contact ledge structure to achieve the small ohmic contact resistance ($R_{\text {c}}$) of GaN-based high electron mobility transistors (HEMTs) on Si for low-voltage RF applications. Without additional photolithography processes, the ledge structure is achieved by magnetron sputtering with …
