A fast video camera is verified to be a powerful t0ol for observation of filaments/blobs near the last closed flux surface （LCFS）. In order to extract the fluctuation component from the raw data of the fast camera, a pre-processing technique, sliding time window averaging subtraction （STWAS） has been developed to remove the background of slowly varying emission from the bulk plasma. By using this pre-processing technique, the fast camera data are analyzed. A method to identify the filaments in the pre-processed image is also discussed.

We investigated the emission properties of Eu3+-doped GdNbO4-based oxide phosphors,aiming at improving the Eu3+emission by codoping of Bi3+and Li+.Eu3+singly doped,Eu3+and Bi3+doubly doped,and Eu3+,Bi3+,and Li+triply doped GdNbO4were prepared using a high-temperature solid-state reaction *** red-orange emissions from Eu3+in the singly doped samples are significantly improved by the codoping of Bi3+,mainly due to the energy transfer from Bi3+to Eu3+.The additional codoping of Li+is found to increase the Eu3+emission *** improvement might be attributed to the increase in the photoluminescent quantum yield originating from larger grain sizes and better crystallinity.A detailed analysis of the X-ray diffraction pattern and the asymmetric ratio estimated from the photoluminescence spectra show that the local lattice environment around Eu3+in GdNbO4does not change significantly with the codoping of Bi3+and Li+.Our results indicate that Li+doping is a promising way to improve the emission properties of rare-earth ion-doped GdNbO4phosphors.

目的对于先前化疗耐受的非小细胞肺癌病人,评价为突变分析而进行重复活检的可行性和安全性。材料与方法这项前瞻性研究获得单位伦理委员会批准,并取得所有病人的知情同意书。选择126例对常规化疗或表皮生长因子受体(EGFR)-酪氨酸激酶抑制剂耐受的非小细胞肺癌病人,对其中94例病人[男31例,女63例,(57±10.3)岁]进行重复活检。32例病人在严格观察胸部CT影像后因各种原因被排除。采用C臂锥形束CT导向进行经皮胸穿肺活检。评价重复活检的技术成功率和进行突变分析的标本充足率。记录任何与活检相关的并发症。结果活检的技术成功率为100%。94例病人中的75例(80%)标本已足以进行突变分析。75例标本中,35例进行了EGFR突变检测,34例进行了间变性淋巴瘤激酶(ALK)基因重组检测,6例两者都进行。结果显示,20例EGFR光敏突变(外显子19或21)为阳性,5例出现EGFRT790M突变,而11例发现间变性淋巴瘤激酶基因重组。94例病人中13例(14%)出现术后并发症。结论当采用严格的CT标准进行操作时,对先前进行化疗的非小细胞肺癌病人进行突变分析时,重复活检是可行的,大约4/5的病人样品足够进行基因分析,而并发症的发生率可以接受。
