| 1 | 利用GOME卫星资料分析北京大气NO_2污染变化显示文摘利用GOME(Global Ozone Monitoring Experiment,全球臭氧监测实验)1996年1月—2002年12月NO2对流层柱浓度月平均卫星遥感资料以及根据北京市2001年1月1日—2002年12月31日NO2污染指数数据计算出的地面NO2日均质量浓度值,分析了北京市城市大气NO2污染变化的季节变化特征以及年际变化,并将2001年1月—2002年12月北京上空GOME NO2对流层柱浓度月平均值变化与北京市地面NO2日均质量浓度月平均值变化进行了比较,结果表明两者随时间的变化趋势具有较好的一致性,据此可以利用GOME NO2对流层柱浓度月平均卫星遥感资料来分析特定区域大气NO2的季节变化和年际变化。 | 江文华 马建中 颜鹏 Andreas Richter John P.Burrows Hendrik Nǖβ | 2006 | 应用气象学报2006,17,1: | 47 |
| 2 | Satellite remote sensing of changes in NO_x emissions over China during 1996-2010显示文摘Satellite derived NO2 column data have been used to study Chinese national fossil fuel consumption and pollutant emissions.Based on NO 2 retrievals from two satellites (GOME and SCIAMACHY) for 1996-2010,we analyzed the characteristics and evolution of regional pollution related to NO x emissions in China.Satellite observations indicated that the highly polluted regions were expanding.Anthropogenic emission dominated areas have expanded from the east to central and western China,and new highly polluted regions have formed throughout the nation.Bottom-up emission estimates suggested a 133% increase in anthropogenic NOx emissions in East Central China during 1996 to 2010,which was lower than the 184% increase of the NO2 columns measured by the satellites.We found that growth rates of NOx emissions have slowed in Chinese megacities over recent years,in contrast to which,the NOx emissions were soaring in medium-sized cities,indicating that strict controls of NOx emissions from coal-fired facilities are required in China. | ZHANG Qiang GENG GuanNan WANG SiWen RICHTER Andreas HE KeBin | 2012 | Chinese Science Bulletin2012,57,22: | 43 |
| 3 | 卫星遥感观测中国1996~2010年氮氧化物排放变化显示文摘利用卫星遥感观测的NO2浓度作为化石能源消耗和污染物排放的示踪,基于GOME和SCIAMACHY的NO2对流层柱浓度数据对1996~2010年间中国氮氧化物排放的时空格局变化进行了分析.结果表明,我国氮氧化物排放的区域性特征日益显著,呈明显的空间扩张态势,原有排放高值区的范围不断扩大,新的高值区不断出现,受人为源排放影响的范围在从东部向中西部扩张.1996~2010年间,华东、华北地区的人为源氮氧化物排放量增加了133%,而同期卫星观测到NO2浓度增长了184%.最近几年特大城市的氮氧化物排放增速在减缓,而中型城市的排放增速在加快,显示我国亟需对燃煤氮氧化物排放进行控制. | 张强 耿冠楠 王斯文 RICHTER Andreas 贺克斌 | 2012 | 科学通报2012,57,16: | 39 |
| 4 | Strategic mining options optimization:Open pit mining, underground mining or both显示文摘Near-surface deposits that extend to considerable depths are often amenable to both open pit mining and/or underground mining. This paper investigates the strategy of mining options for an orebody using a Mixed Integer Linear Programming(MILP) optimization framework. The MILP formulation maximizes the Net Present Value(NPV) of the reserve when extracted with(i) open pit mining,(ii) underground mining, and(iii) concurrent open pit and underground mining. Comparatively, implementing open pit mining generates a higher NPV than underground mining. However considering the investment required for these mining options, underground mining generates a better return on investment than open pit mining. Also, in the concurrent open pit and underground mining scenario, the optimizer prefers extracting blocks using open pit mining. Although the underground mine could access ore sooner, the mining cost differential for open pit mining is more than compensated for by the discounting benefits associated with earlier underground mining. | Ben-Awuah Eugene Richter Otto Elkington Tarrant Pourrahimian Yashar | 2016 | International Journal of Mining Science and Technology2016,26,6: | 15 |

| 11 | Photodynamic therapy:Palliation and endoscopic technique in cholangiocarcinoma显示文摘Cholangiocarcinoma is the primary malignancy arising from the biliary epithelium.The disease is marked by jaundice,cholestasis,and cholangitis.Over 50 percent of patients present with advanced stage disease,precluding curative surgical resection as an option of treatment.Prognosis is poor,and survival has been limited even after biliary decompression.Palliative management has become the standard of care for unresectable disease and has evolved to include an endoscopic approach. Photodynamic therapy(PDT)consists of administration of a photosensitizer followed by local irradiation with laser therapy.Several studies conducted in Europe and the United States have shown a marked improvement in the symptoms of cholestasis,survival,and quality of life.This article summarizes the published experience regarding PDT for cholangiocarcinoma and the steps required to administer this therapy safely. | James A Richter Michel Kahaleh | 2010 | World Journal of Gastrointestinal Endoscopy2010,2,11: | 7 |

| 15 | CT diagnosis of recurrence after pancreatic cancer:Is there a pattern?显示文摘AIM:To investigate predilection sites of recurrence of pancreatic cancer by computed tomography(CT)in follow-up after surgery. METHODS:Seventy seven patients with recurrence after pancreatic cancer surgery were retrospectively identified.The operative technique,R-status,T-stage and development of tumor markers were evaluated. Two radiologists analyzed CT scans with consensus readings.Location of local recurrence,lymph node recurrence and organ metastases were noted.Surgery and progression of findings on follow-up CT were con-sidered as reference standard. RESULTS:The mean follow-up interval was 3.9± 1.8 mo,with a mean relapse-free interval of 12.9± 10.4 mo.The predominant site of recurrence was local (65%),followed by lymph node(17%),liver metastasis (11%)and peritoneal carcinosis(7%).Local recurrence emerged at the superior mesenteric artery(n=28),the hepatic artery(n=8),in an area defined by the surrounding vessels:celiac trunk,portal vein,inferior vena cava(n=22),and in a space limited by the mesenteric artery,portal vein and inferior vena cava(n=17). Lymph node recurrence occurred in the mesenteric root and left lateral to the aorta.Recurrence was confirmed by surgery(n=22)and follow-up CT(n=55).Tumor markers[carbohydrate antigen 19-9(CA19-9),carcinoembryonic antigen(CEA)]increased in accordance with signs of recurrence in most cases(86%CA19-9;79.2% CEA). CONCLUSION:Specific changes of local and lymph node recurrence can be found in the course of the cardinal peripancreatic vessels.The superior mesenteric artery is the leading structure for recurrence. | Tobias Heye Nicola Zausig Miriam Klauss Reinhard Singer Jens Werner Gtz Martin Richter Hans-Ulrich Kauczor Lars Grenacher | 2011 | World Journal of Gastroenterology2011,17,9: | 6 |
| 16 | High-conductivity free-standing Li_(6)PS_(5)Cl/poly(vinylidene difluoride)composite solid electrolyte membranes for lithium-ion batteries显示文摘Bulk-type all-solid-state batteries(ASSBs)using sulfide solid electrolyte are considered as a promising alternative to commercial lithium-ion batteries owing to their high energy density and safety.However,cell energy density is often comparatively low due to use of a thick solid electrolyte separator and a lithium alloy as anode.For achieving high-performance ASSBs,creating a thin free-standing electrolyte with high-conductivity and good cycling stability against lithium anode is essential.In this work,we present Li_(6)PS_(5)Cl/poly(vinylidene difluoride)(LPSCl/PVDF)composite electrolytes prepared by a slurry method.The influence of the PVDF content on the microstructure,morphology,ionic conductivity and activation energy of the LPSCl/PVDF electrolytes is systematically investigated.Free-standing LPSCl/PVDF membranes with a thickness of 100-120 mm and a high ionic conductivity of about 1·10^(-3) S cm^(-1) at 25℃ are obtained.After adding PVDF to the LPSCl electrolyte,the cycling stability of the LPSCl electrolyte against lithium metal improves significantly.Therefore,LPSCl/PVDF composite electrolytes are promising candidates to be used in ASSBs. | Shuo Wang Xue Zhang Sijie Liu Chengzhou Xin Chuanjiao Xue Felix Richter Liangliang Li Lizhen Fan Yuanhua Lin Yang Shen Jurgen Janek Ce-Wen Nan | 2020 | Journal of Materiomics2020,6,1: | 5 |

| 18 | Geographical distribution of the incidence of gastric cancer in Bhutan显示文摘AIM: To estimate the prevalence of gastric cancer(GC) in a cohort of patients diagnosed with GC and to compare it with patients diagnosed with all other types of gastro-intestinal(GI) cancer during the same period.METHODS: Between 2008 and 2013,five-year period,the medical records of all GI cancer patients who underwent medical care and confirm diagnosis of cancer were reviewed at the National Referral Hospital,Thimphu which is the only hospital in the country where surgical and cancer diagnosis can be made. Demographic information,type of cancer,and the year of diagnosis were collected.RESULTS: There were a total of 767 GI related cancer records reviewed during the study period of which 354(46%) patients were diagnosed with GC. There were 413 patients with other GI cancer including; esophagus,colon,liver,rectum,pancreas,gall bladder,cholangiocarcinoma and other GI tract cancers. The GC incidence rate is approximately 0.9/10000 per year(367 cases/5years per 800000 people). The geographic distribution of GC was the lowest in the south region of Bhutan 0.3/10000 per year compared to the central region 1.4/10000 per year,Eastern region 1.2/10000 per year,and the Western region 1.1/10000 per year. Moreover,GC in the South part was significantly lower than the other GI cancer in the same region(8% vs 15%; OR = 1.8,95%CI: 1.3-3.1,P = 0.05). Among GC patients,38% were under the age of 60 years,mean age at diagnosis was 62.3(± 12.1) years with male-to-female ratio 1:0.5. The mean age among patients with all other type GI cancer was 60 years(± 13.2) and male-tofemale ratio of 1:0.7. At time of diagnosis of GC,342(93%) were at stage 3 and 4 of and by the year 2013; 80(23%) GC patients died compared to 31% death among patients with the all other GI cancer(P = 0.08).CONCLUSION: The incidence rate of GC in Bhutan is twice as high in the United States but is likely an underestimate rate because of unreported and undiagnosed cases in the villages. The high incidence of GC in Bhutan could be attributed to the high prevalence of Helicobacter pylori infection that we previously reported. The lowest incidence of GC in Southern part of the country could be due to the difference in the ethnicity as most of its population is of Indian and Nepal origin. Our current study emphasizes on the importance for developing surveillance and prevention strategies for GC in Bhutan. | Tashi Dendup James M Richter Yoshio Yamaoka Kinley Wangchuk Hoda M Malaty | 2015 | World Journal of Gastroenterology2015,21,38: | 4 |
