Discrete Element Method Modeling of an Extrusion Process with Recirculation for Dry Manufacturing of Lithium‐Ion Battery Electrodes

open access: yesBatteries &Supercaps, EarlyView.
On a digitized laboratory extruder, discrete element method modelling is studied, considering two classes of particles representing aggregates of 1) active material and 2) binder and carbon material is studied. Various extrusion scenarios leading to the formation of filaments devoted to the 3D printing of lithium‐ion battery electrodes are studied. The

Evaluación del efecto rejuvenecedor de bio-materiales sobre ligantes para mezclas con alto contenido de asfalto recuperado

open access: yesMateriales de Construccion, 2017
El interés en la utilización de bio-materiales en ingeniería de pavimentos ha crecido significantemente en las últimas décadas debido a la conciencia ambiental sobre el uso de recursos naturales no renovables. En este artículo, se utilizan bio-materiales

Recanalization of Thrombosed Atrial Flow Regulator in Failing Fontan: A Bridge to Transplant

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We report the case of a 10‐year‐old boy (41 kg, 133 cm) with hypoplastic left heart syndrome (mitral and aortic atresia), who underwent staged palliation: Norwood‐Sano at 6 days, Glenn at 7 months, and Fontan completion at 3 years using a 16 mm non‐fenestrated extracardiac Gore‐Tex conduit.

On the density and the structure of the Peirce-like formulae [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Within the language of propositional formulae built on implication and a finite number of variables $k$, we analyze the set of formulae which are classical tautologies but not intuitionistic (we call such formulae - Peirce's formulae).

Restricted Tweedie stochastic block models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based
