| 1 | 健康成人动脉粥样硬化斑块易感性和血栓形成的生物标志物变化与极端空气污染水平相关:北京AIRCHD研究显示文摘空气污染与心血管事件恶化的病理生理机制尚不完全清楚。该文探讨环境空气污染是否可以触发易损斑块.通过全身炎症途径促进血栓形成。方法:在北京AIRCHD研究中.2014-2016年间对73名健康成年人[年龄(23.3±5.4)岁]进行了随访。研究者使用线性混合效应模型评估了空气污染物与动脉粥样硬化斑块易损性、血栓形成和炎症相关生物标志物之间的关系,并使用中介效应分析(mediation analyses)探讨涉及的生物学途径。通过受试者工作特征(receiver operating characteristic,ROC)曲线分析评估每种生物标记物预测环境空气污染暴露的能力。 | 刘青 叶鹏 Xu H Wang T Liu S Brook RD Feng B Zhao Q Song X Yi T Chen J Zhang Y Wang Y Zheng L Rajagopalan S Li J Huang W | 2019 | 中华高血压杂志2019，27，4： | 13 |
| 2 | Terahertz Semiconductor Quantum Well Devices显示文摘For eventually providing terahertz science with compact and convenient devices,terahertz (1~10THz) quantum-well photodetectors and quantum-cascade lasers are investigated.The design and projected detector performance are presented together with experimental results for several test devices,all working at photon energies below and around optical phonons.Background limited infrared performance (BLIP) operations are observed for all samples (three in total),designed for different wavelengths.BLIP temperatures of 17,13,and 12K are achieved for peak detection frequencies of 9.7THz(31μm),5.4THz(56μm),and 3.2THz(93μm),respectively.A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied.The δ-doping density for each period varies from 3.2×1010 to 4.8×1010cm-2.We observe that the lasing threshold current density increases monotonically with doping concentration.Moreover,the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically.Interestingly the observed maximum lasing temperature is best at a doping density of 3.6×1010cm-2. | Liu H C Luo H Ban D Waichter M Song C Y Wasilewski Z R Buchanan M Aers G C SpringThorpe A J Cao J C Feng S L Williams B S Hu Q | 2006 | Journal of Semiconductors2006，27，4： | 2 |
