Intervalles de référence hématologiques chez l'espèce canine avec l'analyseur XT-2000iV (Sysmex)
No full textCette étude expérimentale a eu pour but d'établir les intervalles de référence hématologiques sur une population de 132 chiens sains adultes, de pure race, choisis selon leur préfalence dans le sud ouest de la France, avec l'automate XT-2000iV (Sysmex), en suivant les recommandations internationales de l'IFCC-CLSI avec des procédures de contrôle pré-analytiques bien définies. Les intervalles de référence établis pourront être directement utilisés par des laboratoires possédant le même automate et une population d'animaux malades de même échantillonnage de races que celui de cette étude
Das ISO 9000:2000 Regelwerk - Ansätze zur Integration des VM XT mit einem Qualitätsmanagementsystem
No full textDie Erstellung von Softwareprodukten erfordert eine strukturierte
Vorgehensweise, um eine entsprechend hohe Qualität der Produkte
zu gewährleisten. Vorgehensmodelle unterstützen diese Anforderung,
indem sie einen Rahmen für eine Vorgehensweise zur Entwicklung
der Software definieren. Abhängig von verschiedenen
Anwendungsbereichen, Projektarten, Projektgrößen und Projekttypen
existieren zahlreiche Vorgehensmodelle, die entsprechende
Schwerpunkte setzen. Das aktuelle V-Modell XT ist ein Vorgehensmodell
für Projekte des öffentlichen Bereiches und unterstützt
die Durchführung von IT-Projekten aus Auftraggeber- und Auftragnehmersicht.
Ergänzend zu bisherigen Vorgehensmodellen ist die
Ausschreibungsunterstützung zentraler Bestandteil dieses Models.
Weiters ermöglicht das V-Modell XT "Tailoring", d.h. ein "Maßschneidern",
des Prozesses zur spezifischen Durchführungsplanung
eines Softwareprojekts und erlaubt die individuelle Anpassung des
grundlegenden Vorgehensmodells an unternehmensspezifische Gegebenheiten.
Qualitätssicherungs- und Qualitätsmanagementsysteme stellen
Regelwerke zur unternehmensweiten Ausrichtung der Prozesse auf
allen Ebenen zur Verfügung. Diese Regelungen ermöglichen die Erstellung
gleichförmiger Produkte auf entsprechend hohem Qualitätsniveau.
Dieses Kapitel beschreibt das prozessorientierte, branchenunabhängige
Regelwerk nach ISO 9000:2000 und beleuchtet die Integration
des V-Modells XT in diesen Qualitätsmanagementstandard.
Die Anwendung von Vorgehensmodellen unterstützt den prozessorientierten
Gedanken, in dem die Prozesse in die Prozesslandschaft
eines Unternehmens entsprechend eingebettet werden. Dieses
Kapitel richtet sich an Anwender des V-Modells XT (sowohl Auftraggeber
als auch Auftragnehmer), die einerseits das V-Modell XT
als Vorgehensmodell einsetzen und andererseits allgemeine Anforderungen
eines Qualitätsmanagementsystems nach ISO 9000:2000
erfüllen wollen
Stratego/XT 0.17. A Language and Toolset for Program Transformation
No full textPreprint of paper published in: Science of Computer Programming (Elsevier), 72 (1-2), 2008; doi:10.1016/j.scico.2007.11.003 Stratego/XT is a language and toolset for program transformation. The Stratego language provides rewrite rules for expressing basic transformations, programmable rewriting strategies for controlling the application of rules, concrete syntax for expressing the patterns of rules in the syntax of the object language, and dynamic rewrite rules for expressing context-sensitive transformations, thus supporting the development of transformation components at a high level of abstraction. The XT toolset offers a collection of flexible, reusable transformation components, and tools for generating such components from declarative specifications. Complete program transformation systems are composed from these components. This paper gives an overview of Stratego/XT 0.17, including a description of the Stratego language and XT transformation tools; a discussion of the implementation techniques and software engineering process; and a description of applications built with Stratego/XT.Software Computer TechnologyElectrical Engineering, Mathematics and Computer Scienc
European experience with the second-generation Edwards SAPIEN XT transcatheter heart valve in patients with severe aortic stenosis: 1-year outcomes from the SOURCE XT Registry
No full textOBJECTIVES
The SOURCE XT Registry (Edwards SAPIEN XT Aortic Bioprosthesis Multi-Region Outcome Registry) assessed the use and clinical outcomes with the SAPIEN XT (Edwards Lifesciences, Irvine, California) valve in the real-world setting.
BACKGROUND
Transcatheter aortic valve replacement is an established treatment for high-risk/inoperable patients with severe aortic stenosis. The SAPIEN XT is a balloon-expandable valve with enhanced features allowing delivery via a lower profile sheath.
METHODS
The SOURCE XT Registry is a prospective, multicenter, post-approval study. Data from 2,688 patients at 99 sites were analyzed. The main outcome measures were all-cause mortality, stroke, major vascular complications, bleeding, and pacemaker implantations at 30-days and 1 year post-procedure.
RESULTS
The mean age was 81.4 ± 6.6 years, 42.3% were male, and the mean logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) was 20.4 ± 12.4%. Patients had a high burden of coronary disease (44.2%), diabetes (29.4%), renal insufficiency (28.9%), atrial fibrillation (25.6%), and peripheral vascular disease (21.2%). Survival was 93.7% at 30 days and 80.6% at 1 year. At 30-day follow-up, the stroke rate was 3.6%, the rate of major vascular complications was 6.5%, the rate of life-threatening bleeding was 5.5%, the rate of new pacemakers was 9.5%, and the rate of moderate/severe paravalvular leak was 5.5%. Multivariable analysis identified nontransfemoral approach (hazard ratio [HR]: 1.84; p < 0.0001), renal insufficiency (HR: 1.53; p < 0.0001), liver disease (HR: 1.67; p = 0.0453), moderate/severe tricuspid regurgitation (HR: 1.47; p = 0.0019), porcelain aorta (HR: 1.47; p = 0.0352), and atrial fibrillation (HR: 1.41; p = 0.0014), with the highest HRs for 1-year mortality. Major vascular complications and major/life-threatening bleeding were the most frequently seen complications associated with a significant increase in 1-year mortality.
CONCLUSIONS
The SOURCE XT Registry demonstrated appropriate use of the SAPIEN XT THV in the first year post-commercialization in Europe. The safety profile is sustained, and clinical benefits have been established in the real-world setting. (SOURCE XT Registry; NCT01238497)
XT algorithm for business data exchange
No full textBecause of globalization, multinational firms tend to setup branches across nations for different functions, such as manufacturing lines in China, logistics in Asia, sales points in Europe etc. In order to communicate among each other, the industry has to adopt the same communication platform, use the same terms, and speak the same ldquolanguagerdquo. Therefore, in recent years, a new standardized computer language, eXtensible Business Reporting Language (XBRL), has been developing enhancing different organizations exchanging their financial data without re-enter them. XBRL is a relatively new technology. The research about XBRL instance transformation algorithm is not found yet. In this paper, we developed an algorithm to transform these data into XBRL-compliance format, so that we can take the advantages of XBRL. Our algorithm is named XBRL Transformer (XT). It includes two main modules, XT-Source2XML and XT-XML2XBRL. XT Source2XML transforms a source file, such as MS-Excel, Lotus 123, MS-Word, MS-Access, etc., to a corresponding XML file, and then it outputs the corresponding XML to the second tier, XT-XML2XBRL. After XT-XML2XBRL receives an XML file, it will transform it to XBRL instance file
Finite difference method for detonation waves

XT-ADS sensitivity analysis
No full textThis work has been carried out in the first period (March-June 2010) In which the author Joined the Central Design Team in Mol (B) for the CDT/FASTEF EU FP7 project. Before to start with the deep characterisation foreseen during the WP2 for FASTEF (100 MW LBE cooled reactor, working in both critical and sub-critical modes), a preliminary code tuning has been carried out by adopting the XT-ADS core layout (developed in IP EUROTRANS, EU FP6 project). The tuning deals with the neutronic codes, in particular: ERANOS (deterministic) and MCNPX (Monte Carlo). The main results have been included in the two SCK-CEN calculation notes here reported. The first calculation note (ANS/RMS/TS/ARTD00CDT-02/827/10-15) highlights the main differences between the ERANOS and MCNPX models for XT-ADS. Then the ERANOS input has been modified to consider the same assumptions adopted by MCNPX. A further tuning of both models yields, as a whole, a reduction of the MCNPX-ERANOS keff difference (at BoL) from by about 2700 pcm down to 1000 pcm. The second calculation note (ANS/RMS/TS/ARTD00CDT-02/827/10-16) summarizes the XT-ADS sensitivity analysis performed by ERANOS ver. 2.1 with two different nuclear data Iibraries: JEFF3.1 and ENDF/BVI.8. The study, carried out by exploiting the basics of standard perturbation theory, points out which nuclides, which cross-section and which range of energy yield the most significant impact on the core reactivity. As in the first note, the ERANOS evaluations (performed in a reference and voided configurations) have been compared with the results obtained with the MCNFX code
