| 1 | Cu^+-incorporated TiO_2 overlayer on Cu_2O nanowire photocathodes for enhanced photoelectrochemical conversion of CO_2 to methanol显示文摘In this paper, we report photoelectrochemical(PEC) conversion of carbon dioxide(CO_2) using photocathodes based on Cu_2O nanowires(NWs) overcoated with Cu^+-incorporated crystalline TiO_2(TiO_2–Cu^+ )shell. Cu_2O NW photocathodes show remanent photocurrent of 5.3% after 30 min of PEC reduction of CO_2.After coating Cu_2O with TiO_2–Cu^+ overlayer, the remanent photocurrent is 27.6%, which is an increase by5.2 fold. The charge transfer resistance of Cu_2O/TiO_2–Cu^+ is 0.423 k/cm2, whereas Cu_2O photocathode shows resistivity of 0.781 k/cm2 under irradiation. Mott–Schottky analysis reveals that Cu^+ species embedded in TiO_2 layer is responsible for enhanced adsorption of CO_2 on TiO_2 surface, as evidenced by the decrease of capacitance in the Helmholtz layer. On account of these electrochemical and electronic effects by the Cu^+ species, the Faradaic efficiency(FE) of photocathodes reaches as high as 56.5% when TiO_2–Cu^+ is added to Cu_2O, showing drastic increase from 23.6% by bare Cu_2O photocathodes. | Kangha Lee Seokwon Lee Hyunjin Cho Sunil Jeong Whi Dong Kim Sooho Lee Doh C.Lee | 2018 | Journal of Energy Chemistry2018,27,1: | 3 |

| 4 | Age, socioeconomic features, and clinical factors predict receipt of endoscopic retrograde cholangiopancreatography in pancreatic cancer显示文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP) is the recommended technique for biliary decompression in pancreatic cancer. Previous studies have suggested racial, socioeconomic and geographic differences in diagnosis,treatment and outcomes of pancreatic cancer patients.AIM To examine geographic, racial, socioeconomic and clinical factors associated with utilization of ERCP.METHODS Surveillance, Epidemiology and End Results and linked Medicare claims data were used to identify pancreatic cancer patients between 2000-2011. Claims data were used to identify patients who had ERCP and other treatments. The primary outcome was receipt of ERCP. Chi-squared analyses were used to compare demographic information. Trends in use of ERCP over time were assessed using Cochran Armitage test. Adjusted odds ratios(aORs) and 95% confidence intervals(CIs) for receipt ERCP were calculated using logistic regression,controlling for other characteristics.RESULTS Among 32510 pancreatic cancer patients, 14704(45.2%) underwent ERCP.Patients who had cancer located in the head of the pancreas(aOR 3.27, 95%CI:2.99-3.57), had jaundice(aOR 7.59, 95%CI: 7.06-8.17), cholangitis(aOR 4.22,95%CI: 3.71-4.81) or pruritus(aOR 1.42, 95%CI: 1.22-1.66) and lived in lower education zip codes(aOR 1.14, 95%CI: 1.04-1.24) were more likely to receive ERCP. In contrast, patients who were older(aOR 0.88, 95%CI: 0.83, 0.94), not married(aOR 0.92, 95%CI: 0.86, 0.98), and lived in a non-metropolitan area(aOR0.89, 95%CI: 0.82, 0.98) were less likely to receive ERCP. Compared to white patients, non-white/non-black patients(aOR 0.83, 95%CI: 0.70-0.97) were less likely to receive ERCP. Patients diagnosed later in the study period were less likely to receive ERCP(aOR 2004-2007 0.85, 95%CI: 0.78-0.92; aOR 2008-2011 0.76,95%CI: 0.70-0.83). After stratifying by indications for ERCP including jaundice,racial differences persisted(aOR black patients 0.80, 95%CI: 0.67-0.95,nonwhite/nonblack patients 0.73, 95%CI: 0.58-0.91). Among patients with jaundice, those who underwent surgery were less likely to undergo ERCP(aOR0.60, 95%CI: 0.52, 0.69).CONCLUSION ERCP utilization in pancreatic cancer varies based on patient age, marital status,and factors related to where the patient lives. Further studies are needed to guide appropriate biliary intervention for these patients. | Sheila D Rustgi Sunil P Amin Michelle K Kim Satish Nagula Nikhil A Kumta Christopher J DiMaio Paolo Boffetta Aimee L Lucas | 2019 | World Journal of Gastrointestinal Endoscopy2019,11,2: | 1 |

| 8 | 解决GPS载波相位跳周问题的新方法显示文摘1 引言高精度的GPS定位和导航要求在数据预处理阶段正确修正载波相位观测量中所包含的跳周。仅一二个周期的跳变所引起的测量偏差就使厘米级的定位和导航难以实现。过去十几年内,研究人员已经开发了多种检测和修正跳周的方法。然而,常常仍有一二个跳周不能检测和正确修正,需要分析人员参与,才能完成数据处理,因此,一个操作性能完善的自动化GPS数据预处理器仍是我们可望而不可及的目标。尽管这样。 | Sunil B.Bisnath Donghyun Kim Richard B.Langley 高益军 | 2001 | 控制工程(北京)2001,,4: | 0 |
| 9 | Bulk-Si photonics technology for DRAM interface[Invited]显示文摘We present photonics technology based on a bulk-Si substrate for cost-sensitive dynamic random-access memory(DRAM)optical interface application.We summarize the progress on passive and active photonic devices using a local-crystallized Si waveguide fabricated by solid phase epitaxy or laser-induced epitaxial growth on bulk-Si substrate.The process of integration of a photonic integrated circuit(IC)with an electronic IC is demonstrated using a 65 nm DRAM periphery process on 300 mm wafers to prove the possibility of seamless integration with various complementary metal-oxide-semiconductor devices.Using the bulk-Si photonic devices,we show the feasibility of high-speed multidrop interface:the Mach–Zehnder interferometer modulators and commercial photodetectors are used to demonstrate four-drop link operation at 10 Gb∕s,and the transceiver chips with photonic die and electronic die work for the DDR3 DRAM interface at 1.6 Gb∕s under a 1∶4 multidrop configuration. | Hyunil Byun Jinkwon Bok Kwansik Cho Keunyeong Cho Hanmei Choi Jinyong Choi Sanghun Choi Sangdeuk Han Seokyong Hong Seokhun Hyun TJJeong Ho-Chul Ji In-Sung Joe Beomseok Kim Donghyun Kim Junghye Kim Jeong-Kyoum Kim Kiho Kim Seong-Gu Kim Duanhua Kong Bongjin Kuh Hyuckjoon Kwon Beomsuk Lee Hocheol Lee Kwanghyun Lee Shinyoung Lee Kyoungwon Na Jeongsik Nam Amir Nejadmalayeri Yongsang Park Sunil Parmar Junghyung Pyo Dongjae Shin Joonghan Shin Yong-hwack Shin Sung-Dong Suh Honggoo Yoon Yoondong Park Junghwan Choi Kyoung-Ho Ha Gitae Jeong | 2014 | Photonics Research2014,2,3: | 0 |
