  • Edutella: A P2P Networking Infrastructure Based on RDF
  • 2002
  • Konferensbidrag (refereegranskat)abstract
    • Metadata for the World Wide Web is important, but metadata for Peer-to-Peer (P2P) networks is absolutely crucial. In this paper we discuss the open source project Edutella which builds upon metadata standards defined for the WWW and aims to provide an RDFbased metadata infrastructure for P2P applications, building on the recently announced JXTA Framework. We describe the goals and main services this infrastructure will provide and the architecture to connect Edutella Peers based on exchange of RDF metadata. As the query service is one of the core services of Edutella, upon which other services are built, we specify in detail the Edutella Common Data Model (ECDM) as basis for the Edutella query exchange language (RDF-QEL-i) and format implementing distributed queries over the Edutella network. Finally, we shortly discuss registration and mediation services, and introduce the prototype and application scenario for our current Edutella aware peers.

  • Design and baseline characteristics of the Incremental Decrease in End Points through Aggressive Lipid Lowering study
  • 2004
  • Ingår i: American Journal of Cardiology. - : Elsevier BV. - 0002-9149 .- 1879-1913. ; 94:6, s. 720-724
  • Tidskriftsartikel (refereegranskat)abstract
    • The Incremental Decrease in End Points through Aggressive Lipid Lowering (IDEAL) study is an investigator-initiated trial designed to determine whether additional clinical benefit might be gained through a strategy that decreases levels of low-density lipoprotein cholesterol levels better than those currently achieved with established statin therapy in patients who have coronary heart disease. IDEAL is a multicenter prospective, randomized, open-label, blinded, end point classification study. Patients who had myocardial infarction were randomized to prescription treatment with 80 mg/day of atorvastatin or 20 mg/day of simvastatin (the dose was increased to 40 mg/day at week 24 in those patients whose plasma total cholesterol remained >5.0 mmol/L, or 190 mg/dl, or whose low-density lipoprotein cholesterol remained >3.0 mmol/L, or 115 mg/dl). The primary clinical outcome variable is the time to initial occurrence of a major coronary event, which is defined as nonfatal acute myocardial infarction, coronary death, or resuscitated cardiac arrest. The study is designed to have a power of 90% to detect a relative decrease of 20% in the atorvastatin-group compared with the simvastatin-group in the number of major events caused by coronary heart disease over ~5.5 years. The 8,888 randomized patients had the following characteristics: mean age 61.7 ± 9.5 years, 19.1% women (mean age 64.0 ± 9.5 years), baseline total cholesterol 5.1 ± 1.0 mmol/L (197 mg/dl), low-density lipoprotein cholesterol 3.2 ± 0.9 mmol/L (124 mg/dl), and high-density lipoprotein cholesterol 1.2 ± 0.3 mmol/L (46 mg/dl). Drug treatment before randomization consisted of statins in 77% of patients, aspirin in 78.9%, ß blockers in 75.1%, and angiotensin-converting enzyme inhibitors in 30%. © 2004 by Excerpta Medica, Inc.
