Several learning algorithms in classification and structured prediction are formulated as large scale optimization problems. We show that a generic iterative reformulation and resolving strategy based on the progressive hedging algorithm from stochastic programming results in a highly parallel algorithm when applied to the large margin classification problem with nonlinear kernels. We also underline promising aspects of the available analysis of progressive hedging strategies. [less ▲]

The paper discusses elementary control strategies to control the phase of an oscillator. Both feedforward and feedback (P and PI) control laws are designed based on the phase response curve (PRC) calculated from the linearized model. The performance is evaluated on a popular model of circadian oscillations. [less ▲]

Aims: Left ventricular (LV) shape and LV dyssynchrony are two cofactors associated with functional mitral regurgitation (MR) in patients with heart failure. Both can be accurately examined by real-time three-dimensional echocardiography (3DE). We examined the relationship between dynamic MR and exercise-induced changes in LV shape and synchronicity using 3DE. Methods and results: Fifty patients with systolic LV dysfunction underwent 2D and 3D quantitative assessment of LV function, shape, and synchronicity at rest and during symptom-limited exercise test. According to the magnitude of change in MR, patients were divided into EMR group (15 patients, 30%), if the degree of MR increased during test, and NEMR group. During exercise, the changes in LV volumes and ejection fraction were similar in both groups, whereas changes in mitral valvular deformation parameters, in LV sphericity index, and in the extent of LV dyssynchrony were more pronounced in the EMR group. At rest, only the 3D sphericity index could distinguish the two groups. By stepwise multiple regression model, dynamic changes in the systolic dyssynchrony index, sphericity index, and coaptation distance were associated with dynamic MR (r2 = 0.45, P = 0.012). Conclusion: Dynamic MR during exercise is related to the 3D changes in LV shape and in LV synchronicity. [less ▲]

The main mission statement of the European Association of Echocardiography (EAE) is ‘to promote excellence in clinical diagnosis, research, technical development, and education in cardiovascular ultrasound in Europe’. As competence and quality control issues are increasingly recognized by patients, physicians, and payers, the EAE has established recommendations for training, competence, and quality improvement in echocardiography. The purpose of this document is to provide the requirements for training and competence in echocardiography, to outline the principles of quality measurement, and to recommend a set of measures for improvement, with the ultimate goal of raising the standards of echocardiographic practice in Europe.

Ces dernières années, la pollution de l’air est devenue une préoccupation pour ses impacts environnementaux et sur la santé. Les réglementations contrôlant les émissions d’air pollué se sont d’ailleurs multipliées. Face à ces problèmes, des solutions de traitement ont été développées, certaines utilisant même les potentialités des microorganismes pour épurer les effluents industriels. Les limites de ces traitements biologiques classiques sont même en voie d’être repoussées par une nouvelle génération de systèmes : les réacteurs biphasiques. [less ▲]

Dans le contexte actuel de crise, le secteur laitier est en difficulté. Il devient alors essentiel de maîtriser les coûts liés à chaque phase d’élevage tout en optimisant la croissance des jeunes animaux. La première mise à l’herbe est, dans ce cadre, une étape importante et sensible. Cependant, la méconnaissance de cet aspect de la part des éleveurs et le recours à des pratiques bien souvent inappropriées engendrent des frais superflus sans garantir de manière systématique l’état sanitaire du cheptel.

A simple relaxation consisting of two rows of a simplex tableau is a mixed-integer set with two equations, two free integer variables, and nonnegative continuous variables. Recently, Andersen et al. and Cornuéjols and Margot showed that the facet- defining inequalities of this set are either split cuts or intersection cuts obtained from lattice-free triangles and quadrilaterals. From an example given by Cook et al. it is known that one particular class of facet-defining triangle inequality does not have finite split rank. In this paper we show that all other facet-defining triangle and quadrilateral inequalities have finite split rank. [less ▲]

A 2D numerical flow model, developed at the Research unit of Hydrology, Applied Hydrodynamics and Hydraulic Constructions at ULg, has been applied to flows in a macro-rough channel. The model solves the shallow water equations (SWE) with a two length scale, depth-integrated k-type approach for turbulence modeling. Data for the comparison have been provided by experiments conducted at the Laboratory of Hydraulic Constructions at EPFL. In the experiments with different non-prismatic channel configurations, namely large-scale cavities at the side walls, three different 2D flow characteristics could be observed in cavities. With the used numerical model features, especially regarding turbulence and friction modeling, a single set of bottom and side wall roughness could be found for a large range of discharges investigated in a prismatic channel. For the macro rough configurations, the numerical model gives an excellent agreement between experimental and numerical results regarding backwater curves and flow patterns if the side wall cavities have low aspect ratios. For configurations with high aspect ratios, the head loss generated by the preservation of important recirculation gyres in the cavities is slightly underestimated. The results of the computations reveal clearly that the separation of turbulence sources in the mathematical model is of great importance. Indeed, the turbulence related to 2D transverse shear effects and the 3D turbulence, generated by bed friction, can have very different amplitude. When separating these two effects in the numerical models, most of the flow features observed experimentally can be reproduced accurately. [less ▲]

En 1905 el escritor festivo publicó una interesante parodia de la novela de H. G. Wells _First Men on the Moon_, que había sido traducida al español aquel mismo año. Esta parodia puede considerarse una muestra del interés que ya para entonces despertaba el novelista inglés en España. Ahora bien, el modo en que Pérez Zúñiga transforma el argumento de Wells es síntoma no sólo de una visión desencantada del mundo, sino también de un profundo escepticismo respecto de las virtudes de la ciencia.
