肺栓塞患者血浆D-二聚体水平及其他指标与远期全因死亡率的关系

open access: yesZhongguo shiyan zhenduanxue, 2023
目的 探讨肺栓塞患者血浆D-二聚体水平及其他指标是否可以预测肺栓塞(PE)患者的长期全因死亡率。方法 选取2017年1月至2022年12月期间在吉林大学第一医院乐群院区住院的308名PE患者,根据结局分为生存组(n=205)和死亡组(n=103)。构建ROC曲线以预测全因死亡率的最佳D-二聚体截断值。计算AUC并获得全因死亡率的预测灵敏度和特异度。建立多因素logistic回归模型来评估D-二聚体水平与全因死亡率的关系。通过绘制Kaplan-Meier曲线显示D-二聚体水平与累积生存时间的关系 ...

Generative AI as a Learning Companion for Self‐Directed Second Language Learning Among Secondary School Students: A Mixed‐Methods Study

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Self‐directed Learning (SDL) is an important skill for learners of all ages and phases of life. Generative AI facilitates self‐directed second language (L2) learning by providing interactive, personalised access to online resources. However, existing research on AI‐assisted self‐directed L2 learning focuses on adult learners in higher ...

Functionalized Silica‐Constructed Self‐Supporting Composite Separator for Lithium Metal Batteries

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lithium metal batteries (LMBs) are considered highly promising next‐generation energy storage systems owing to their exceptionally high theoretical specific capacity and ultralow electrochemical potential. Nevertheless, the practical deployment of LMBs is still severely restricted by the uncontrollable formation and propagation of lithium ...

Constructing Ultrafine Ru Nanoclusters via a Dual‐Confinement Strategy: Synergizing Hierarchical Pores and Electronic Modulation for Efficient Lignin Hydrogenolysis

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Lignin hydrogenolysis is a promising route to separable aromatic monomers, yet practical upgrading is still hindered by macromolecular mass‐transfer limitations and the aggregation/deactivation of metal sites. Herein, we propose a “dual‐confinement” strategy to construct ultrafine Ru nanoclusters supported on lignin‐based N‐doped hierarchical ...
