[Evolution and scientific impact of research grants from the spanish society of cardiology and spanish heart foundation (2000-2006)].
Abstract Introduction and objectives The Sociedad Espanola de Cardiologia (Spanish Society of Cardiology) every year awards grants to finance research in the field of cardiovascular diseases. The aim of this study is to identify the impact of these investments during the period 2000-2006 from the subsequently published articles in scientific journals. Methods Using the identifying data of each project as search terms, all articles that resulted from these grants were located in the Spanish Indice Medico Espanol and Indice Bibliografico Espanol en Ciencias de la Salud databases, and in Science Citation Index-Expanded and Scopus. Descriptive statistical analysis of these articles included typ…
Computation of travelling wave solutions of scalar conservation laws with a stiff source term
Abstract In this paper we propose a nonoscillatory numerical technique to compute the travelling wave solution of scalar conservation laws with a stiff source term. This procedure is based on the dynamical behavior described by the associated stationary ODE and it reduces/avoids numerical errors usually encountered with these problems, i.e., spurious oscillations and incorrect wave propagation speed. We combine this treatment with either the first order Lax–Friedrichs scheme or the second order Nessyahu–Tadmor scheme. We have tested several model problems by LeVeque and Yee for which the stiffness coefficient can be increased. We have also tested a problem with a nonlinear flux and a discon…
