| 1 | 生态环境曲面建模基本定理及其应用显示文摘在高精度曲面建模方法和地球表层系统建模基本定理研究结果基础上,演绎提出了生态环境曲面建模基本定理.以京津冀地区为案例,对基于生态环境曲面建模基本定理的空间升尺度、空间降尺度、空间插值、数据融合和模型-数据同化等算法进行了实证研究,与传统算法精度进行了比较分析.结果表明,由于基于生态环境曲面建模基本定理的各种算法综合了外蕴量信息和内蕴量信息,同时运用了理论上完善的信息综合方法,使海拔高度曲面的升尺度均方根误差至少降低了9m,年平均气温未来情景的降尺度精度至少提高16%,年平均气温过去变化趋势的数据融合精度至少提高70%,年平均降雨量过去变化趋势的空间插值精度至少提高0.2%,碳储量的模型-数据同化精度提高了40%.文章最后讨论了生态曲面建模基本定理亟待解决的五大理论问题和四大应用基础问题. | 岳天祥 赵娜 刘羽 王轶夫 张斌 杜正平 范泽孟 史文娇 陈传法 赵明伟 宋敦江 王世海 宋印军 闫长青 李启权 孙晓芳 张丽丽 田永中 王薇 王英安 马胜男 黄宏胜 卢毅敏 王情 王晨亮 王玉柱 鹿明 周伟 刘熠 尹笑哲 王宗 包正义 赵苗苗 赵亚鹏 焦毅蒙 Ufra NASEER 范斌 李赛博 杨阳 John P.WILSON | 2020 | 中国科学:地球科学2020，50，8： | 8 |
| 2 | 新型冠状病毒消退阈值建模方法显示文摘On 21 December of 2019,four lower respiratory tract samples were collected from patients with pneumonia of unknown cause in Wuhan,China[1].This disease was later diagnosed as a coronavirus disease.The World Health Organization(WHO)named the coronavirus disease as COVID-19 on 11 February and declared a pandemic on 11 March 2020.The COVID-19 is a previously unknown disease with no tools available for pharmaceutical management at the early stage of its outbreak. | 岳天祥 范泽孟 范斌 杜正平 John P.Wilson 尹笑哲 赵娜 王英安 周成虎 | 2020 | Science Bulletin2020，65，15： | 4 |
| 3 | Prospective evaluation of point-of-care ultrasound for pre-procedure identification of landmarks versus traditional palpation for lumbar puncture显示文摘BACKGROUND: The objective of this study is to determine if point-of-care ultrasound(POCUS) pre-procedure identification of landmarks can decrease failure rate, reduce procedural time, and decrease the number of needle redirections and reinsertions when performing a lumbar puncture(LP).METHODS: This was a prospective, randomized controlled trial comparing POCUS preprocedure identifi cation of landmarks versus traditional palpation for LP in a cohort of patients in the emergency department and intensive care unit.RESULTS: A total of 158 patients were enrolled. No signifi cant difference was found in time to completion, needle re-direction, or needle re-insertion when using POCUS when compared to the traditional method of palpation.CONCLUSION: Consistent with fi ndings of previous studies, our data indicate that there was no observed benefi t of using POCUS to identify pre-procedure landmarks when performing an LP. | shadi lahham priel schmalbach sean p.wilson lori ludeman mohammad subeh jocelyn chao nadeem albadawi niki mohammadi john c.fox | 2016 | World Journal of Emergency Medicine2016，7，3： | 3 |
| 4 | Simpli?ed point-of-care ultrasound protocol to con?rm central venous catheter placement:A prospective study显示文摘BACKGROUND: The current standard for con? rmation of correct supra-diaphragmatic central venous catheter(CVC) placement is with plain ? lm chest radiography(CXR). We hypothesized that a simple point-of-care ultrasound(POCUS) protocol could effectively con? rm placement and reduce time to con? rmation.METHODS: We prospectively enrolled a convenience sample of patients in the emergency department and intensive care unit who required CVC placement. Correct positioning was considered if turbulent flow was visualized in the right atrium on sub-xiphoid, parasternal or apical cardiac ultrasound after injecting 5 cc of sterile, non-agitated, normal saline through the CVC.RESULTS: Seventy-eight patients were enrolled. POCUS had a sensitivity of 86.8%(95%CI 77.1%–93.5%) and speci? city of 100%(95%CI 15.8%–100.0%) for identifying correct central venous catheter placement. Median POCUS and CXR completion were 16 minutes(IQR 10–29) and 32 minutes(IQR 19–45), respectively.CONCLUSION: Ultrasound may be an effective tool to confirm central venous catheter placement in instances where there is a delay in obtaining a con? rmatory CXR. | Scan P.Wilson Samer Assaf Shadi Lahham Mohammad Subeh Alan Chiem Craig Anderson Samantha Shwe Ryan Nguyen John C.Fox | 2017 | World Journal of Emergency Medicine2017，8，1： | 2 |
| 5 | Procedural simulation:medical student preference and value of three task trainers for ultrasound guided regional anesthesia显示文摘BACKGROUND: Ultrasound guided regional anesthesia is widely taught using task trainer models. Commercially available models are often used; however, they can be cost prohibitive. Therefore, alternative 'homemade' models with similar fidelity are often used. We hypothesize that professional task trainers will be preferred over homemade models. The purpose of this study is to determine realism, durability and cleanliness of three different task trainers for ultrasound guided nerve blocks.METHODS: This was a prospective observational study using a convenience sample of medical student participants in an ultrasound guided nerve block training session on January 24 th, 2015. Participants were asked to perform simulated nerve blocks on three different task trainers including, 1 commercial and 2 homemade. A questionnaire was then given to all participants to rate their experiences both with and without the knowledge on the cost of the simulator device.RESULTS: Data was collected from 25 participants. The Blue Phantom model was found to have the highest fidelity. Initially, 10(40%) of the participants preferred the Blue Phantom model, while 10(40%) preferred the homemade gelatin model and 5(20%) preferred the homemade tofu model. After cost awareness, the majority, 18(72%) preferred the gelatin model.CONCLUSION: The Blue Phantom model was thought to have the highest fidelity, but after cost consideration the homemade gelatin model was preferred. | Shadi Lahham Taylaur Smith Jessa Baker Amanda Purdy Erica Frumin Bret Winners Sean P.Wilson Abdulatif Gari John C.Fox | 2017 | World Journal of Emergency Medicine2017，8，4： | 2 |
| 6 | 新型冠状病毒肺炎在不同国家的基本传染数动态显示文摘本文对新型冠状病毒(简称新冠病毒)肺炎基本传染数算法进行了改进,并运用改进算法对累计确诊人数较多的6个国家(美国、印度、巴西、俄罗斯、秘鲁和哥伦比亚)新冠病毒肺炎疫情动态进行了比较分析.研究结果表明,诸如封城、检疫隔离、关闭学校、限制旅行和扩大社交距离等防控措施对各国遏制冠状病毒传播发挥了至关重要的作用.然而,由于各国新冠病毒防控措施的执行力度大相径庭,效果差异很大.截至2020年9月11日,累计确诊人数在秘鲁、巴西、美国和哥伦比亚分别占总人口的2.23%、2.06%、2.00%和1.43%,新冠病毒传播仍在继续. | 岳天祥 范斌 赵亚鹏 John P.Wilson 杜正平 王情 尹笑哲 段晓男 赵娜 范泽孟 林晖 周成虎 | 2021 | Science Bulletin2021，66，3： | 1 |
