Antinucleus Production at RHIC

Light antinuclei may be formed in relativistic heavy ion collisions via final state coalescence of antinucleons. The yields of antinuclei are sensitive to primordial antinucleon production, the volume of the system at kinetic freeze-out, and space-momentum correlations among antinucleons at freeze-out. We report here preliminary STAR results on antideuteron and antihelion production in 130A GeV Au+Au collisions. These results are examined in a coalescence framework to elucidate the space-time structure of the antinucleon source.Comment: 4 pages, 3 figures, talk given at Quark Matter 200

Time-Delayed Subsidies: Interspecies Population Effects in Salmon

Cross-boundary nutrient inputs can enhance and sustain populations of organisms in nutrient-poor recipient ecosystems. For example, Pacific salmon (Oncorhynchus spp.) can deliver large amounts of marine-derived nutrients to freshwater ecosystems through their eggs, excretion, or carcasses. This has led to the question of whether nutrients from one generation of salmon can benefit juvenile salmon from subsequent generations. In a study of 12 streams on the central coast of British Columbia, we found that the abundance of juvenile coho salmon was most closely correlated with the abundance of adult pink salmon from previous years. There was a secondary role for adult chum salmon and watershed size, followed by other physical characteristics of streams. Most of the coho sampled emerged in the spring, and had little to no direct contact with spawning salmon nutrients at the time of sampling in the summer and fall. A combination of techniques suggest that subsidies from spawning salmon can have a strong, positive, time-delayed influence on the productivity of salmon-bearing streams through indirect effects from previous spawning events. This is the first study on the impacts of nutrients from naturally-occurring spawning salmon on juvenile population abundance of other salmon species

CoDoSA: A Lightweight, XML-Based Framework for Integrating Unstructured Textual Information

One of the most fundamental dimensions of information quality is access. For many organizations, a large part of their information assets is locked away in Unstructured Textual Information (UTI) in the form of email, letters, contracts, call notes, and spreadsheet. In addition to internal UTI, there is also a wealth of publicly available UTI on websites, in newspapers, courthouse records and other sources that can add value when combined with internally managed information. This paper describes a system called Compressed Document Set Architecture (CoDoSA) designed to facilitate the integration of UTI into a structured database environment where it can be more readily accessed and manipulated. The CoDoSA Framework comprises an XML-based metadata standard and an associated Application Program Interface (API). It further describes how CoDoSA can facilitate the storage and management of information during the ETL (Extract, Transform, and Load) process to integrate unstructured UTI information. It also explains how CoDoSA promotes higher information quality by providing several features that simplify the governance of metadata standards and enforcement of data quality constraints across different UTI applications and development teams. In addition, CoDoSA provides a mechanism for inserting semantic tags into captured UTI, tags that can be used in later steps to drive semantic-mediated queries and processes
