Efficient and accurate numerical modeling of ultrasonic wave scattering in polycrystalline materials using a space-discontinuous Galerkin framework

Ultrasonic wave scattering is an interesting phenomenon in which the wave propagation is locally disturbed by the heterogeneities in the media, such as relative crystallographic misorientation in polycrystalline materials. In non-destructive…

On the benefits of a multiscale domain decomposition method to model-order reduction for frictional contact problems

In this paper, the efficiency of a multiscale strategy based on a domain decomposition method (DDM) for model-order reduction of time-dependent frictional contact problems is presented. The proposed strategy relies on the LArge Time INcrement (LATIN…

Defect modes in imperfect periodic structures

Lack of periodicity in engineering structures can arise because of imperfections in the production process or a particular purpose to produce desirable physical effects. This contribution presents a series of numerical simulations that…

Prospective randomized double-blind study to evaluate the superiority of Vasopressin versus Norepinephrine in the management of the patient at renal risk undergoing cardiac surgery with cardiopulmonary bypass (NOVACC trial)

BackgroundCardiac surgery-associated acute kidney injury (CS-AKI) affects up to 30% of patients, increasing morbidity and healthcare costs. This condition results from complex factors like ischemia-reperfusion injury and renal hemodynamic changes,…
