BACKGROUND The clinical significance of complete revascularization for ST segment elevation myocardial infarction (STEMI) patients during admission is still debatable. METHODS A total of 1406 STEMI patients from the Korean Myocardial Infarction Registry with multivessel diseases without cardiogenic shock who underwent primary percutaneous coronary intervention (PPCI) were analyzed. We used pr...

In this paper, we present total variation diminishing (TVD) multigrid methods for computing the steady state solutions for systems of hyperbolic conservation laws. An efficient multigrid method should avoid spurious numerical oscillations. This can be achieved by designing methods which preserve monotonicity and TVD properties through the use of upwind interpolation and restriction techniques. ...

INTRODUCTION Waiting-time prior to radiotherapy is a well-known problem. This study aims to determine the impact of time on tumor growth in a patient population with squamous-cell carcinoma of the head and neck (SCCHN). MATERIAL AND METHODS In a consecutive cohort, all patients with both a diagnostic scan and a treatment-planning scan were identified. In total 648 patients were seen, and 414 ...

This paper examines the effects and potential benefits of utilising Web Application Firewalls (WAFs) and database proxies in SQL injection testing of web applications and services. We propose testing the WAF itself to refine and evaluate its security rules and prioritise fixing vulnerabilities that are not protected by the WAF. We also propose using database proxies as oracles for black-box sec...

To enhance vehicle maneuverability and stability, a controller with 4-wheel steering (4WS), electronic stability control (ESC) torque vectoring device (TVD) under constraint on the front slip angles is designed in this research. In controller, allocation method adopted to generate yaw moment via 4WS, ESC TVD. If angle added for generating moment, performance of can be further deteriorated. This...

The influence of different diffuser configurations on the flow stability and aerodynamic performance a centrifugal compressor stage with mass coefficient 0.196 is numerically investigated. Research results show that traditional full-height vaned (TVD) deteriorates rapidly, shroud-side partial (SVD) displays better adaptability in off-design conditions. SVD can suppress development vortices gene...

An Eulerian TVD code and a Lagrangian SPH code are used to simulate the off-axis collision of equal-mass main sequence stars in order to address the question of whether stellar mergers can produce a remnant star where the interior has been replenished with hydrogen due to significant mixing. Each parent main sequence star is chosen to be found near the turnoff, with hydrogen depleted in the cor...

Target value design (TVD) is a management approach that applies target costing in the and construction industry. TVD enables project environment with favorable characteristics to generate value. However, because TVD’s primary assessment cost, cost can be met without necessarily achieving project’s full This research action implement housing explores generation of using analysis model (VAM) stud...

We derive TVD remeshing formulas for particle methods. The derivation is inspired from a finite-difference analysis but the method retains the essential features of particle methods. Numerical illustrations give evidence of the improved stability and computational cost resulting from these new algorithms. Résumé Schémas de remaillage TDV en méthodes particulaires. On décrit dans cette note des ...
