Recently, we suggested that the cell coat of the surface epithelial cells of the palatal shelves and especially its sialyl groups are implied in the adhesion process which initiates the constitution of the secondary palate. In this work, use of cationized ferritin which interacts with anionic receptors of the plasma membrane give us the possibility to render these sialic acids visible. After five minutes incubation in presence of cationized ferritin, the labeling particles are distributed in monolayer over the plasmalemma of epithelial cells. Subsequent incubation in cationized ferritin free medium results in clustering of the marker followed by the detachment of the labeled patches. Otherwise, incubation in the presence of neuraminidase from Clostridium perfringens before the polycationic ligand contact prevents labeling. We think that lateral migration modifications of the anionic receptor could be associated with changes of the shelves capacity to adhere. [less ▲]

A l’heure où l’industrie cimentière est majoritairement responsable de la production de CO2 dans le secteur de la construction, il s’avère utile de compenser cette production par un phénomène inverse: la captation du CO2. Ce processus d’absorption de CO2, appelé carbonatation, améliore certaines propriétés du béton lors de la conversion du dioxyde de carbone CO2 en carbonate de calcium CaCO3. Les préoccupations environnementales actuelles motivent l’étude de la carbonatation dans le but de maximiser l'absorption du dioxyde de carbone. Les granulats recyclés, produits à base de déchets de béton concassés mécaniquement, peuvent prendre place dans de nouvelles applications en béton. Ils peuvent remplacer les granulats naturels en tout ou en partie, épargnant ainsi l’extraction des matières premières naturelles. La combinaison des deux approches vise à élaborer un produit dont l’impact environnemental est réduit au minimum. [less ▲]

Hundred and thirteen male adult albino rats (Wistar) have successively been submitted to 3 CFR, 3 FI 30, 3 FI 60, 3 FI 90 and 40 FI 120 seconds sessions. The daily sessions lasted in every case 30 minutes. Daily distributions of the Curvature Indice (Fry, Kelleher & Cook, 1960) values showed that the mean value increased up to a stabilization point at the 20th FI 120 seconds session and that the inter-individual differences as estimated by the standard deviation increased progressively throughout the session series. Rank correlations (Kendall Tau t) computed between individual Curvature Index values from adjacent or remote sessions were highly osgnificant and showed that the level of adjustment to the FI schedule early in training has a predictive value.

Turtle doves, pigeons and rats were trained on fixed-interval (FI) 2, 4, 6, 8- and 110-mi, schedules. Response rates were at each FI value, higher in both bird psecies. They decreased as FI value increased in rats and pigeons. Rat's curvature indices were in all cases superior to those of birds, and the turtle dove differed significantly from pigeons at 2, 4 and 6 min. Curvature indices decreased in rats and increased in birds (except for 2 turtle doves) as the FI value increased. These results question the traditionally assumed cross-species generality of performance in FI schedules. [less ▲]

Motivated by the problem of learning a linear regression model whose parameter is a large fixed-rank non-symmetric matrix, we consider the optimization of a smooth cost function defined on the set of fixed-rank matrices. We adopt the geometric optimization framework of optimization on Riemannian matrix manifolds. We study the underlying geometries of several well-known fixed-rank matrix factorizations and then exploit the Riemannian geometry of the search space in the design of a class of gradient descent and trust-region algorithms. The proposed algorithms generalize our previous results on fixed-rank symmetric positive semidefinite matrices, apply to a broad range of applications, scale to high-dimensional problems and confer a geometric basis to recent contributions on the learning of fixed-rank non-symmetric matrices. We make connections with existing algorithms in the context of low-rank matrix completion and discuss relative usefulness of the proposed framework. Numerical experiments suggest that the proposed algorithms compete with the state-of-the-art and that manifold optimization offers an effective and versatile framework for the design of machine learning algorithms that learn a fixed-rank matrix.
