Providing traceability for neuroimaging analyses

IntroductionWith the increasingly digital nature of biomedical data and as the complexity of analyses in medical research increases, the need for accurate information capture, traceability and accessibility has become crucial to medical researchers in the pursuance of their research goals. Grid- or Cloud-based technologies, often based on so-called Service Oriented Architectures (SOA), are increasingly being seen as viable solutions for managing distributed data and algorithms in the bio-medical domain. For neuroscientific analyses, especially those centred on complex image analysis, traceability of processes and datasets is essential but up to now this has not been captured in a manner that facilitates collaborative study.Purpose and methodFew examples exist, of deployed medical systems based on Grids that provide the traceability of research data needed to facilitate complex analyses and none have been evaluated in practice. Over the past decade, we have been working with mammographers, paediatricians and neuroscientists in three generations of projects to provide the data management and provenance services now required for 21st century medical research. This paper outlines the finding of a requirements study and a resulting system architecture for the production of services to support neuroscientific studies of biomarkers for Alzheimer's disease.ResultsThe paper proposes a software infrastructure and services that provide the foundation for such support. It introduces the use of the CRISTAL software to provide provenance management as one of a number of services delivered on a SOA, deployed to manage neuroimaging projects that have been studying biomarkers for Alzheimer's disease.ConclusionsIn the neuGRID and N4U projects a Provenance Service has been delivered that captures and reconstructs the workflow information needed to facilitate researchers in conducting neuroimaging analyses. The software enables neuroscientists to track the evolution of workflows and datasets. It also tracks the outcomes of various analyses and provides provenance traceability throughout the lifecycle of their studies. As the Provenance Service has been designed to be generic it can be applied across the medical domain as a reusable tool for supporting medical researchers thus providing communities of researchers for the first time with the necessary tools to conduct widely distributed collaborative programmes of medical analysis.     

Soccer Science and the Bayes Community: Exploring the Cognitive Implications of Modern Scientific Communication

Science is a form of distributed analysis involving both individual work that produces new knowledge and collaborative work to exchange information with the larger community. There are many particular ways in which individual and community can interact in science, and it is difficult to assess how efficient these are, and what the best way might be to support them. This paper reports on a series of experiments in this area and a prototype implementation using a research platform called CACHE. CACHE both supports experimentation with different structures of interaction between individual and community cognition and serves as a prototype for computational support for those structures. We particularly focus on CACHE‐BC, the Bayes community version of CACHE, within which the community can break up analytical tasks into “mind‐sized” units and use provenance tracking to keep track of the relationship between these units.     

徐寿与"中西医汇通"主张的由来

关于“中西医汇通”的由来,以往多认为是在1890年,李鸿章为《万国药方》（中文版）作序时最早提出,但根据掌握的资料,徐寿在1876年所作“医学论”一文中就已经提出了“中西医汇通”的主张,可以说他是提出“中西医汇通”主张的第一人。     

不同种源鱼腥草中黄酮类成分质量分数变异规律的研究

目的：揭示全国主产区鱼腥草种质资源中黄酮类成分质量分数变异规律,为鱼腥草优良品种选育提供基础。方法：用液相色谱法测定22个种源鱼腥草中金丝桃苷、槲皮苷和槲皮素质量分数,并分析形态特征、地理位置、生长性状与金丝桃苷、槲皮苷和槲皮素质量分数的关系。结果与结论：不同种源鱼腥草中金丝桃苷、槲皮苷和槲皮素质量分数存在显著差异,与植物形态存在一定的关系,与种源经纬度没有显著的相关性。因此,在针对鱼腥草金丝桃苷、槲皮苷和槲皮素成分选择新品种时,应重点考虑鱼腥草植株的形态特征。     

Reverse paintings on glass—A new approach for dating and localization

Samples from 20 reverse paintings on glass from different regions have been analyzed by NAA with the aim to deduce the place and date of their origin. A separation of earlier and later paintings was due to different concentrations of K and Na, because a sodium-containing flux came into use after 1870. Since in southern Germany quartz sand, and in the eastern area quartz rock had been used for glass manufacture, specific impurities could be used to distinguish southern from eastern glasses.
