Contribution of Suburban Land Use Landscape Characteristics to Urban Heat Island Intensity at Varying Gradients in Shenyang

Jiaxing Xin, Ying Cui, Jun Yang et al. · 2025 · IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing

The intensification of the urban heat island (UHI) effect poses a serious threat to public health, particularly in cities. Effectively mitigating UHI has been a focus of national and international academic research over the last decades. However, most contemporary research has focused on land use mitigation measures within urban areas, with less emphasis on suburban land use. To address this research gap and explore spatial characteristics, we analyzed the driving mechanism of suburban land use patterns on UHI intensity (UHII) within the main urban area of Shenyang City based on high spatial r

Evaluation of the effectiveness of surgical resection and ablation for the treatment of early‐stage hepatocellular carcinoma: A retrospective cohort study

Bilan Yang, Xiaoli Xi, Hongsheng Yu et al. · 2024 · Cancer Reports

Abstract Background The optimal treatment strategy for early‐stage hepatocellular carcinoma (HCC) remains controversial, specifically in regard to surgical resection (SR) and ablation. The aim of this study was to investigate the impact of SR and ablation on recurrence and prognosis in early‐stage HCC patients, to optimize treatment strategies and improve long‐term survival. Methods A retrospective analysis was conducted on 801 patients diagnosed with Barcelona Clinic Liver Cancer (BCLC) stage 0/A HCC and treated with SR or ablation between January 2015 and December 2019. The effectiveness and
