We study certain function algebras and their operator algebra completions on r-discrete abelian groupoids, the corresponding conditional expectations, maximal abelian subalgebras (masa) and eigen-functionals. We give a semidirect product decomposition for an abelian groupoid. This is done through a matched pair and leads to a C*-diagonal (for a special case). We use this decomposition to study ...

We study the asymptotic behaviour of nonnegative solutions to: ut = pum using an entropy estimate based on a sub-family of the Gagliardo-Nirenberg inequalities – or, in the limit casem = (p 1) 1, on a logarithmic Sobolev inequality inW 1;p – for which optimal functions are known. Diffusions nonlinéaires et constantes optimales dans des inégalités de type Sobolev : comportement asymptotique d’éq...

Programmed death ligand 1 (PD-L1) is highly expressed in many cancers. We investigated the expression of PD-L1 and its relationship with vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 and KI-67 expression in 64 patients with primary glioma. The expression rate of PD-L1 in glioma patients was 78.12%. PD-L1 levels correlated with the tumor grade (p = 0.013), VEGF status (p ...

It is well known that bilinguals perform better in their first language (L1) than in their second lanaguage (L2) in a wide range of linguistic tasks. In recent studies, however, the authors have found that bilingual participants can demonstrate faster response times to L1 stimuli than to L2 stimuli in one classification task and the reverse in a different classification task. In the current stu...

A strategy for multiple removal consists of estimating a model of the multiples and then adaptively subtracting this model from the data by estimating shaping filters. A possible and efficient way of computing these filters is by minimizing the difference or misfit between the input data and the filtered multiples in a least-squares sense. Therefore, the signal is assumed to have minimum energy...

Little is known about language minority community college students’ depth of L2 academic vocabulary knowledge, including how it relates to their breadth of L2 academic vocabulary knowledge and the relationship to their L1 skills. This exploratory study was carried out with a sample of 10 language minority students enrolled in either advanced ESL language classes or introductory content courses ...

Masked translation priming between languages with different scripts exhibits a marked asymmetry in lexical decision, with much stronger priming from L1 to L2 than from L2 to L1. This finding was confirmed in a lexical decision task with Chinese–English bilinguals who were late learners of English. Following a suggestion made by Bradley (1991), the experiment was repeated using a speeded episodi...

Study of smut fungi on Liliaceae resulted to propose a new genus and three new combinations: Vankya Ershad, type V. ornithogali (Schmidt et Kunze) Ershad, based on Uredo ornithogali Schmidt et Kunze, V. heufleri (Fuckel) Ershad, based on Ustilago heufleri Fuckel, and V. vaillantii (L.-R. et C. Tulasne) Ershad, based on Ustilago vaillantii L.-R. et C. Tulasne.

Two new penalty methods for sparse reconstruction are proposed based on two types of difference of convex functions (DC for short) programming in which the DC objective functions are the difference of l1 and lσq norms and the difference of l1 and lr norms with r > 1. By introducing a generalized qterm shrinkage operator upon the special structure of lσq norm, we design a proximal gradient algor...
