A Complete Onium Program with R2D at RHIC II

Following on the discovery of a strongly interacting quark-gluon plasma (QGP) at RHIC, a program of detailed quarkonia measurements is crucial to understanding the nature of deconfinement. Lattice QCD calculations suggest a sequential melting of the quarkonia states in the deconfined medium. Such a melting would lead to a suppression in the measured charmonium and bottomonium yields. However, distinguishing a true suppression from shadowing, absorption, and recombination effects requires detailed measurements of the charmonium states (J/psi, psi', and chi_c) and bottomonium states (Y(1S), Y(2S), and Y(3S)). Also, since measurements are needed not only in A+A, but also in p+p for determining primary yields and in p+A for evaluating absorption, the detector should perform well in all collision environments. To fully realize the program outlined above, a new detector will be required at RHIC-II. We present a proposal for a complete quarkonia program and the abilities of a new detector, R2D, to meet the stated requirements. Comparisons will be made with proposed upgrades to existing RHIC detectors and with the upcoming LHC program.Comment: 3 pages, submitted proceedings from PANIC '0

Multiple hierarchies : new aspects of an old solution

In this paper, we present the Multiple Annotation approach, which solves two problems: the problem of annotating overlapping structures, and the problem that occurs when documents should be annotated according to different, possibly heterogeneous tag sets. This approach has many advantages: it is based on XML, the modeling of alternative annotations is possible, each level can be viewed separately, and new levels can be added at any time. The files can be regarded as an interrelated unit, with the text serving as the implicit link. Two representations of the information contained in the multiple files (one in Prolog and one in XML) are described. These representations serve as a base for several applications

Eliciting Faculty Requirements for Research Data Repositories

4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PresentationsDate: 2009-06-04 10:30 AM – 12:00 PMIn a two-year project sponsored by the Institute of Museum and Library Services, investigators from Purdue University and the University of Illinois, Urbana-Champaign are addressing the question, "Which researchers are willing to share data, when, with whom, and under what conditions?" In-depth interviews and surveys have been conducted with 19 faculty researchers in 12 different disciplines about their scientific workflow and range of research outputs (e.g., raw data through published forms) to identify needs for discovery, access, use, and repurposing of their data. As the study enters its second year, we are ready to share preliminary findings that relate the needs for data curation that were expressed by the subjects to possible functional requirements that a data repository system can provide to meet those needs. These early results can provide immediate and valuable insights to developers and implementers of data repositories as well as practitioners who are developing and managing data collections.Institute of Museum and Library Service

Glu: An Online Type 1 Diabetes Information Community

This research paper examines the online health community Glu (MyGlu.org), a type 1 diabetes social media site. Type 1 diabetes is a chronic medical condition that requires constant and specialized medical attention. Online health communities like Glu, are an important part of maintaining a healthy lifestyle for many of its members. This study discusses the composition of this information community, the motivations of its members, and the benefits members gain through their participation. It describes the major characteristics of the community and focuses on the information needs of type 1 diabetics. It concludes with reflections on how libraries and LIS professionals can better serve the information needs of health communities like Glu and accommodate their needs in the physical space of the library
