| 1 | Earthquake relocation and 3-dimensional crustal structure of P-wave velocity in cen-tral-western China显示文摘采用中国中西部地区(2l°~36°N,98°~112°E)193个地震台在1992~1999年间记录到的9988次地震的Pg和Sg震相走时的读数资料,用Roecker的SPHYPIT90程序,反演了该地区三维地壳P波速度结构,并用SPHREL3D90程序进行了地震的重新定位.反演结果揭示了中国中西部地区地震P波速度结构明显的横向不均匀性,这些不同深度上波速的横向变化多以该地区的活动断裂为分界线.可以看出活动断裂两侧存在明显的速度反差.通过重新定位,得到了6459次地震的震源参数,这些精确定位的地震震中明显沿该区活动断裂呈现条带状分布,其范围和尺度清晰地表示了这一地区地震活动与活动断裂的紧密关系.其中,82%重新精确定位的事件的震源深度在20km以内.这一结果与笔者用双差地震定位法得到的重新定位的震源深度分布相一致. | 杨智娴 于湘伟 郑月军 陈运泰 倪晓晞 Winston CHAN | 2004 | 地震学报2004,26,1: | 26 |
| 2 | 用接收函数研究中国地壳结构显示文摘收集处理了中国国家数字地震台网(CNDSN)48个地震台记录的大量高质量的宽频带远震波形资料,用于计算中国大尺度的地壳厚度横向变化和VP/VS值(泊松比)变化。用一种统计方法来挑选每个台站的互相关接收函数,多数台站的记录在200条以上。由常用的H-к(地壳厚度和VP/VS值)方法可以发现H和к之间有明显的折衷关系。因此在H-к域内,经常出现多个极大值。为了减少这种折衷,这里引入一种权重函数,用它计算出每个H-к网格上PS转换震相与反射震相的相关性。用四次方根叠加方法进一步降低线性叠加带来的不相关噪声。在减少H-к折衷方面,这种修改后的方法非常有效,得出了可靠的地壳厚度值和VP/VS值。在中国东部的地壳厚度为31~33km,莫霍界面相对平坦和清晰。在中国西部,地壳相对较厚,地形变化很大。天山褶皱带的莫霍界面厚度为51km,青藏高原中部的莫霍界面厚度达84km。在东经100°到110°之间,所谓的南北带上发生了过渡转变,此地区表现为频繁的地震活动和明显的重力异常。中国大陆地壳的VP/VS平均值约为1.730(σ=0.249),比全球大陆地壳的平均值1.78(σ=0.27)低很多。较低的VP/VS值意味着在中国大陆的地壳最低层中缺少镁铁层。 | Hrvoje Tkali Winston Chan 许若冰 | 2010 | 世界地震译丛2010,41,6: | 2 |

| 4 | Earthquake relocation and 3-dimensional crustal structure of P-wave velocity in central-western China显示文摘A simultaneous inversion of earthquake relocation and three-dimensional crustal structure of P-wave velocity in central-western China (21°N~36°N, 98°E~112°E) were performed in this paper. The crustal P-wave velocity model and earthquake relocation for this region are obtained using Pg and Sg phase readings of 9 988 earthquakes from 1992 to 1999 recorded at 193 seismic stations within central-western China by SPHYPIT90 and SPHREL3D90 programs. A lateral inhomogeneous structure of P-wave velocity in this region was obtained. Obvious contrast of P-wave velocities was revealed on both sides of active fault zones. Relocated epicenters of6 459 events show clear lineation along active faults, which indicated a close correlation between seismicity and the active faults in this region. Focal depths of 82% relocated events ranged from 0 to 20 km, which is in good agreement with that from double-difference earthquake location algorithm. | YANG Zhi-xian(杨智娴) YU Xiang-wei(于湘伟) ZHENG Yue-jun(郑月军) CHEN Yun-tai(陈运泰) NI Xiao-xi(倪晓晞) Winston CHAN | 2004 | Acta Seismologica Sinica(English Edition)2004,17,1: | 1 |

| 8 | Adherence to cardiovascular medications in the South Asian population:A systematic review of current evidence and future directions显示文摘AIM: To review methods of assessing adherence and strategies to improve adherence to cardiovascular disease(CVD) medications,among South Asian CVD patients. METHODS: We conducted a systematic review of English language studies that examined CVD medication adherence in South Asian populations from 1966 to April 1,2015 in SCOPUS and Pub Med. Working in duplicate,we identified 61 studies. After exclusions,26 studies were selected for full text review. Of these,17 studies were included in the final review. We abstracted data on several factors including study design,study population,method of assessing adherence and adherence rate. RESULTS: These studies were conducted in India(n = 11),Pakistan(n = 3),Bangladesh(n = 1),Nepal(n = 1) and Sri Lanka(n = 1). Adherence rates ranged from 32%-95% across studies. Of the 17 total publications included,10 focused on assessing adherence to CVD medications and 7 focused on assessing the impact of interventions on medication adherence. The validated Morisky Medication Adherence Scale(MMAS) was used as the primary method of assessing adherence in five studies. Three studies used validated questionnaires similar to the MMAS,and one study utilized Medication Event Monitoring System caps,with the remainder of the studies utilizing pill count and self-report measures. As expected,studies using non-validated self-report measures described higher rates of adherence than studies using validated scale measurements and pill count. The included intervention studies examined the use of polypill therapy,provider education and patient counseling to improve medication adherence. CONCLUSION: The overall medication adherence rates were low in the region,which suggest a growing need for future interventions to improve adherence. | Julia M Akeroyd Winston J Chan Ayeesha K Kamal Latha Palaniappan Salim S Virani | 2015 | World Journal of Cardiology2015,7,12: | 1 |
