SS6: Sensor Data Mining For Tracking Description: The rapid development of advanced sensors and their joint application provide a foundation for new paradigms to combat the challenges that arise in target detection, tracking and forecasting in harsh environments with poor prior information. As a consequence, the sensor community has expressed interest in novel data mining methods coupling traditional statistical techniques for substantial performance enhancement. For example, the advent of multiple/massive sensor systems provides very rich observation at high frequency yet low financial cost, which facilitates novel perspectives based on data clustering and model learning to deal with false alarms and misdetection, given little statistical knowledge about the objects, sensors and the background. Numerical fitting and regression analysis provide another unlimited means to utilize the unstructured context information such as “the trajectory is smooth” for continuous-time target trajectory estimation. Incorporating additional, readily available information to constrain the adaptive response and to combat poor scenario knowledge, has shown promise as a means of restoring sensor capability over a range of challenging operating conditions as well as to deal with a variety of challenging problems that makes traditional approaches awkward. The purpose of this special section is to assemble and disseminate information on recent, novel advances in sensor signal and data mining techniques and approaches, and promote a forum for continued discussion on the future development. Both theoretical and practical approaches in the area are welcomed. Organizers: Tiancheng Li ( t.c.li@usal.es ) Haibin Ling ( hbling@temple.edu ) and Genshe Chen ( gchen@intfusiontech.com ) The topics of interest of this specialsection include but are not limited to: · Adaptive filtering · Learning for state space models · Manoeuvring target detectionand tracking · Object recognition/classificationusing sonar, radar, video, soft data sources, etc. · Clustering approaches fortracking · Regression analysis for trajectoryestimation · Multiple Intelligent dataassociation/fusion · Machine learning technology fortracking Submission链接: http://www.fusion2017.org/submissions.html 欢迎投稿!

为庆祝中国女药学家屠呦呦因发现青蒿素抗疟活性而获得2015年诺贝尔生理学或医学奖,并纪念1977年《科学通报》首次报道“青蒿素结构研究协作组”从菊科植物黄花蒿( Artemisia annual L.)中分离出青蒿素, Science Bulletin 于 2016年第一期出版了由 Science Bulletin 主编、中科院上海生命科学研究院植物生理生态研究所 陈晓亚 院士和北京大学 许智宏 院士组织的“ 青蒿素研究进展 ”专题。 2015年,屠呦呦作为第一个获得诺贝尔奖的中国本土科学家,极大地鼓舞了国内各学科领域,尤其是奋战在植物代谢和中国传统中药活性成分研究领域的科研工作者。中国传统中药是开掘不尽的宝藏,某些中药天然成分很可能具有不可替代的药用功能。 青蒿素就是一个极好的例子,作为一线抗疟药,青蒿素类药物的应用不仅挽救了全球数百万人的生命,而且促进了其他科学领域的发展。青蒿素化学结构复杂,在天然植物中含量极低,很难直接提取,从而促进了人工合成青蒿素领域的研究;而化学合成的低效率限制了青蒿素的应用,又促进了青蒿素合成生物学的发展。科学家现在已经可以成功地将青蒿素的生物合成酶基因克隆到酵母中,生成半合成的青蒿素。 为了使读者进一步了解青蒿素的研究进展,本专题为大家呈现了四篇综述文章和一篇评论: 1) 陈晓亚 院士研究团队系统综述了中国传统药用植物中活性成分生物合成的研究进展,突显了现代分子生物学、基因组学、功能基因组学和高通量分析化学技术的发展对药用植物研究的极大推动; 2)上海交通大学 唐克轩 教授的团队回顾了青蒿素生物合成的转录调控研究历程,为基因工程改良形成高产量青蒿植物提供了理论依据; 3)上海第二军医大学 张磊 教授的研究团队概述了青蒿素的特异性合成场所——青蒿分泌型腺毛的发育与调控研究进展,提出通过改造改良腺毛来提高青蒿素产量的新思路; 4)中科院上海药物研究所 左建平 教授研究团队综述了青蒿素类化合物的另一种重要应用——治疗自身免疫疾病的研究进展; 5)美国北卡罗莱纳州立大学的 谢德玉 教授对青蒿素研究获诺贝尔奖进行了剖析和评论。 希望该专题能使读者对青蒿素合成与应用研究的最新进展有所了解,并且从青蒿素的发现和研究中得到有益启示。 具体精彩内容,敬请关注以下文章: SPECIAL TOPIC: Advances in Artemisinin Study 1.

Science 专题:癌症基因组学 在 2001 年完成人类 基因组 测序后,许多的 研究人员 立即将目光放到了利用这些信息来更好地了解 遗传学 上。最近,越来越多的研究确定了表观遗传学在癌症的发生、形成及发展过程中起效应。从鉴别与遗传性癌症相关的单 基因变异 的前基因组时代转向, 测序技术 的进步使得研究人员能够利用 全基因组 方法来检测基因组间的差异,以及肿瘤和患者 DNA 的表观遗传调控。 最新一期 (3 月 29 日 ) 的《科学》 (Science) 杂志以“ Cancer Genomics ”为题对癌症 基因组学 进行了专题介绍,其中包括 1 篇介绍性文章, 1 篇评论文章, 2 篇新闻文章和 4 篇综述文章。除此之外在 Science Signaling 和 Science Careers 也有相关的内容。 由于一直以来没有任何单一的遗传变异或表观遗传效应被确定为对抗所有癌症的靶标,因而不幸目前还没有治疗癌症的灵丹妙药。在一篇题为“ Cancer Genome Landscapes ”的综述评论中, Vogelstein 等利用来自 100 多个癌症 基因组测序 计划的信息,总结出了一套有关肿瘤 生物学 的明确原则,随后还讨论了癌症基因组分析对于疾病的早期检测和治疗预计会产生的临床影响。 在题为“ Diagnostic Cancer Genome Sequencingand the Contribution of Germline Variants ”的综述文章中, Kilpivaara 和 Aaltonen 提出为全基因组测序揭示个体患者临床相关突变设立标准,以消除 实验室 与临床之间存在的差异。 在题为“ Cancer Pharmacogenomics: EarlyPromise, But Concerted Effort Needed ”的综述文章中, McLeod 等概述了如何应用药物基因组学信息来识别和定制癌症靶向药物。最后,在题为“ Epigenetic Reprogrammingin Cancer ”的文章中, Suv à、 Riggi 和 Bernstein 等调查了表观遗传调控控制细胞命运的机制,并鉴别了癌症和 细胞分化 之间的相似之处。 此外,《 Science Signaling 》杂志也将分别于 3 月 26 日和 4 月 6 日发布一些相关内容,阐明基因组或 蛋白质 组中癌症相关改变导致信号改变,促使肿瘤形成、转移和药物耐受的机制。 在一篇新闻文章中, Science 对 Elaine Mardis 进行了人物介绍。 Elaine Mardis 专门从事 DNA 技术技术开发,这使得她成为了癌症基因组研究中的先锋人物。此外,文章还探讨了如何利用测序研究揭示个别肿瘤异质性,提出了一些治疗问题。另一篇新闻文章则介绍了一位生物 信息学 家 F á tima Al-Shahrou ,他主要从事基因组注释工作,帮助为癌症患者选择更有效的药物。 技术上不断取得突破,加上测序成本大大降低,表明在我们不久的将来,常规癌症治疗将不再侧重于癌症起源器官,而是会将焦点转向癌症的基因组特征上。未来的基本目标是,能够读取埋藏在我们身体中的复杂密码,在治疗过程中为每位患者确定最好的治疗方案。 SPECIAL ISSUE | 29 MARCH 2013 Cancer Genomics http://www.sciencemag.org/site/special/cancergenomics/ INTRODUCTION —With the completion of the human genome in 2001, many researchers immediately set their sights on using this information to better understand the genetics and, more recently, epigenetic effects identified during the initiation, development, and progression of cancer. Moving from the pre–genome-era identification of single gene variants associated with hereditary cancers, advances in sequencing technology have enabled the use of a whole-genome approach to examine the differences between the genomes, and epigenetic regulation, of tumor and patient DNA. This issue of Science examines how these advances are shaping our current understanding of cancer at the genomic level. 其他相关连接: Science 新闻 :“10,000 个癌症基因组计划 ” 引高度关注 http://www.ebiotrade.com/newsf/2013-3/201337104818894.htm 《自然》发表国际肿瘤基因组计划专题报道 http://news.sciencenet.cn/htmlnews/2010/4/230962.shtm Nature: 99 个癌症基因组全面解析 http://www.ebiotrade.com/newsf/2012-10/20121026121207641.htm 科学家成功绘制出肺癌和皮肤癌基因图谱 http://news.sciencenet.cn/htmlnews/2009/12/226248.shtm

http://www.nature.com/ngeo/journal/v5/n4/full/ngeo1448.html NATURE GEOSCIENCE | EDITORIAL What lies beneath Nature Geoscience 5, 229 (2012) doi:10.1038/ngeo1448 Published online 30 March 2012 The mid-ocean ridges mark the lines along which the Earth is turning itself inside out through the process of plate tectonics. Advances in technology are helping to reveal the intricate details of the magma systems that feed the rifting process. The deep ocean has long been a source of fascination, not least because of its inaccessibility. Only in the nineteenth century was the naive assumption that the ocean basins are like bathtubs — deepest in the middle, and shallow near the coasts — overthrown by measurements made by scientists on board the HMS Challenger. Using the crude method of dropping weighted ropes over the side of their vessel, they discovered relatively shallow depths in the middle of the Atlantic Ocean, the first hints of a mid-ocean ridge. Since then, the mid-ocean ridges have been identified as a global system of volcanic activity, where oceanic crust is generated from upwelling molten mantle rock. Occasionally, the rift system extends on land to areas where new ocean basins will eventually appear. About 70% of Earth's mid-ocean ridge system has been mapped ( http://ocean-ridge.ldeo.columbia.edu/index.html ), but the shape and geometry of the magma systems that underlie the rifts and supply new oceanic crust are less well known. Simple models attempt to predict the shape and depth of the volcanic plumbing system by assuming that magma chamber geometry reflects a balance between the speed of plate separation — characteristic for a given section of the mid-ocean ridge system — and the supply of magma. Ridges are thus broadly classified into slow- and fast-spreading systems, with a range of plate separation between about 1 and 20 cm per year. But three Letters and a Review article in this issue imply that the volcanic plumbing system is sensitive to a larger variety of factors, and a classification by spreading rate may be less useful than has been thought.(大洋中脊可以大体划分为快速和慢速扩张系统,板块分离速度在1-20厘米每年,本期有三篇通讯和一篇综述文章阐述火山系统受到多种因素控制,仅仅依靠扩张速度并不可靠) Specifically, fast-spreading plates are expected to be characterized by high heat fluxes, high rates of magma production, fast magma cooling rates and a shallow, narrow and confined magma chamber. However, Canales et al. (page 279) found an intricate network of magma bodies at the fast-spreading East Pacific Rise, as well as the expected shallow and elongated chamber at the hot rift axis. The network was distributed over an area up to 8 kilometres from the axis, in parts of the crust that had been thought to be quite cool .(一般说来,快速扩张中心一般式高热量,高岩浆产量,快速冷却速率和浅的分布局限的岩浆房;本次研究发现东太平洋中脊地热带的快速扩张中心可以分布在8公里的范围,而且部分区域过去认为是相当冷的) Nor could the anticipated fast cooling rates be confirmed for the East Pacific Rise at a closer look: probing minerals in a different section of the ridge, Rioux and colleagues (page 275) found that it took the magma a similar length of time to cool in this fast-spreading setting as had been inferred earlier for the slow-spreading Mid-Atlantic Ridge (C. J. Lissenberg et al. Science 323, 1048–1050; 2009). (东太平洋快速扩张中心与大西洋中脊慢速扩张中心的岩浆冷却时间相似) The slow-spreading ridge in Afar, East Africa — although a somewhat special case because it is has not been inundated by seawater yet — does not conform to expectation either. Rather than low heat fluxes and a deep broad magma chamber, Pagli and colleagues (page 284) diagnose just the type of elongated narrow chamber that had been associated with fast spread. In a Review article that compares this ridge with another slow-spreading centre exposed on land in Iceland, Wright and colleagues (page 242) suggest that pulses of volcanic activity supply the magma. (陆地上的慢速扩张中心研究表明:东非裂谷带慢速扩张中心,不是满的热通量和神的宽广的岩浆房,而是狭长而且窄的岩浆房;与冰岛的慢速扩张中心相比,显示火山活动提供了岩浆) The unusual setting of these rifts — on land instead of under the sea — in Iceland and Afar could help explain their characteristics to some degree: in a submarine ridge, heat is quickly swept away by the hydrothermal circulation in the rift systems. By contrast, the nascent ridges in Afar and Iceland are missing the ocean's cooling influence and are purported to be affected by hot mantle plumes. The anomalously high temperatures could cause the magmatic systems there to seem more similar to their fast-spreading counterparts beneath the ocean. (陆地上的慢速扩张中心如东非裂谷带以及冰岛慢速扩张中心的,都没有还是冷却循环作用,加上热的地幔柱的影响形成他们的特征) The twentieth and twenty-first centuries have seen remarkable advances in technology that have allowed us to peek under the Earth's crust. As ever with the availability of more detailed data, existing concepts of what lies beneath will need to be adjusted. Rather than a simple trade-off between plate spreading rate and magma supply, the geometry of the magma system at spreading ridges seems to be sensitive to a wide variety of factors. The presence or absence of an ocean, a mantle plume and off-axis magmatism that is potentially related to fractures in the crust, can all play a central role in shaping the evolution of the Earth's rift systems.

China - a call for papers. Francis Chan , Jin Ling Tang , Sian Griffiths , Joseph Sung , Michael R Phillips , Helena Wang . Chinese University of Hong Kong, Hong Kong, China. Suicide Research and Prevention Centre, Shanghai Mental Health Centre, Shanghai Jiaotong University School of Medicine, Shanghai Jiaotong University, Shanghai, China. Global Health Institute, Emory University, Atlanta, GA, USA. The Lancet, Beijing 100738, China. Health-care reform in China remains high on the political agenda as moves are made to develop the role of primary care and improve the quality of care. Whilst good progress is being made, large discrepancies still exist between standards of care in rural and urban areas of China. Recognised challenges include the need for investment in community-based care, a shortage of appropriately trained health-care workers, and the promotion of evidence-based prescribing practice and control of prescribing. The Lancet continues to support clinical researchers and health professionals in China, and today publishes its latest issue themed around China's health-care reform and clinical research. The Lancet's 2013 China themed issue will provide a further opportunity to present some of the outstanding public health and clinical research being carried out in China, and review progress on implementation of the health-care reform programme. The 2013 China issue will be published to coincide with a symposium to be held in Hong Kong in June, 2013 as part of the fiftieth anniversary of the Chinese University of Hong Kong. In addition to advances in clinical practice, major themes including food safety, migration, and the effect of social policies on people's livelihood will be addressed. We invite submissions of high-quality research from China or from research teams working on health in China. Priority will be given to reports of randomised trials that advance the evidence-base of prevention and clinical treatment of disease, and to articles about research on health-system evaluation. Reports on progress in tackling non-communicable diseases, as well as improving care for the elderly, will be welcome. Other studies that have the potential to change clinical and public health practice in China and other countries in the region are also welcome. Please submit manuscripts online before Nov 22, 2012, and mention in your cover letter that the submission is in response to this call for papers.
