| 1 | 动态88小时:美国地质调查局国家地震信息中心对2011年3月11日M_W9.0日本地震的响应显示文摘引言
2011年3月11日日本本州岛东海岸附近海域发生的M9.0地震(Tohoku earthquake,以下称“东日本大地震”——译者注)及其引发的海啸造成数以万计的人员死亡,造成的财产损失可能超过1万亿美元,这是有历史记录以来最严重的自然灾害之一。 | Gavin P Hayes Paul S Earle Harley M Benz David J Wald Richard W Briggs 左玉玲(译) 郑需要(校) | 2011 | 国际地震动态2011，，8： | 4 |
| 2 | 三维炭纤维预型体上烷烃气的催化炭沉积(英文)显示文摘研究了承载镍催化剂的三维(3D)炭纤维预型体,在含氢或无氢条件下,乙烷和合成天然气在其上面化学气相沉积形成的炭沉积率和碳纳米构结物。观察了炭沉积所获石墨纳米纤维、碳纳米管和石墨碳壳,得知沉积碳的纳米结构取决于沉积温度和碳源气组成。在650℃~800℃温间,总沉积时程直至12h,研究了烃类碳源气在氢气平衡下,从体积分数100%到20%变化情况。经Ni(NO3)2-6H2O甲醇溶液浸渍的3D炭纤维预型体在炭沉积前因溶液分解可还原出Ni。采用质量变化测定法、热谱-质谱分析仪、SEM、TEM和XRD对样品进行表征。结果表明:纤维状炭与囊包炭的比率随氢气含量的增加而增加,随反应温度的增高而减少。出乎意料的是,氢气的添加并不延长催化剂的寿命。该工艺过程对炭/炭复合材料的制备展示出良好的潜力。 | Matthew J Thornton Gavin S Walker | 2009 | 新型炭材料2009，24，3： | 2 |

| 4 | Reliability of ultrasound ovarian-adnexal reporting and data system amongst less experienced readers before and after training显示文摘BACKGROUND The 2018 ovarian-adnexal reporting and data system(O-RADS)guidelines are aimed at providing a system for consistent reports and risk stratification for ovarian lesions found on ultrasound.It provides key characteristics and findings for lesions,a lexicon of descriptors to communicate findings,and risk characterization and associated follow-up recommendation guidelines.However,the ORADS guidelines have not been validated in North American institutions or amongst less experienced readers.AIM To evaluate the diagnostic accuracy and inter-reader reliability of ultrasound ORADS risk stratification amongst less experienced readers in a North American institution with and without pre-test training.METHODS A single-center retrospective study was performed using 100 ovarian/adnexal lesions of varying O-RADS scores.Of these cases,50 were allotted to a training cohort and 50 to a testing cohort via a non-randomized group selection process in order to approximately equal distribution of O-RADS categories both within and between groups.Reference standard O-RADS scores were established through consensus of three fellowship-trained body imaging radiologists.Three PGY-4 residents were independently evaluated for diagnostic accuracy and inter-reader reliability with and without pre-test O-RADS training.Sensitivity,specificity,positive predictive value,negative predictive value(NPV),and area under the curve(AUC)were used to measure accuracy.Fleiss kappa and weighted quadratic(pairwise)kappa values were used to measure inter-reader reliability.Statistical significance was P<0.05.RESULTS Mean patient age was 40±16 years with lesions ranging from 1.2 to 22.5 cm.Readers demonstrated excellent specificities(85%-100%pre-training and 91%-100%post-training)and NPVs(89%-100%pre-training and 91-100%post-training)across the O-RADS categories.Sensitivities were variable(55%-100%pre-training and 64%-100%post-training)with malignant ORADS 4 and 5 Lesions pre-training and post-training AUC values of 0.87-0.95 and 0.94-098,respectively(P<0.001).Nineteen of 22(86%)misclassified cases in pre-training were related to mischaracterization of dermoid features or wall/septation morphology.Fifteen of 17(88%)of posttraining misclassified cases were related to one of these two errors.Fleiss kappa inter-reader reliability was‘good’and pairwise inter-reader reliability was‘very good’with pre-training and post-training assessment(k=0.76 and 0.77;and k=0.77-0.87 and 0.85-0.89,respectively).CONCLUSION Less experienced readers in North America achieved excellent specificities and AUC values with very good pairwise inter-reader reliability.They may be subject to misclassification of potentially malignant lesions,and specific training around dermoid features and smooth vs irregular inner wall/septation morphology may improve sensitivity. | Prayash Katlariwala Mitchell P Wilson Yeli Pi Baljot S Chahal Roger Croutze Deelan Patel Vimal Patel Gavin Low | 2022 | World Journal of Radiology2022，14，9： | 2 |
| 5 | 限域在介孔材料中的氨硼烷的催化脱氢性能和化学储氢性能(英文)显示文摘报道了同时采用催化剂和限域基体对氨硼烷(BH_3NH_3)脱氢性能的影响.结果发现,非贵金属催化剂和孔状限域基体能显著改变氨硼烷的储氢性能.填充在介孔二氧化硅中含Co催化剂的氨硼烷在75℃或90℃能释放出4%或9%纯氢,进一步用锂修饰介孔二氧化硅可使氨硼烷脱氢速度更快,但产生氢气、氨气和二硼烷的混合气.氨硼烷热分解活化能的降低导致填充在介孔二氧化硅中含催化剂的氨硼烷具有较快的动力学和热力学行为. | 夏勇德 WALKER Gavin S 朱艳秋 | 2012 | 复旦学报(自然科学版)2012，51，5： | 2 |
