In this paper, we consider the flow of fresh and saltwater in a saturated porous medium in order to describe the seawater intrusion. Starting from a formulation with...

We prove a revised version of Laver's indestructibility theorem which slightly improves over the classical result. An application yields the consistency of...

Various theorems for the preservation of set-theoretic axioms under forcing are proved, regarding both forcing axioms and axioms true in the Levy-Collapse. These show...

We report on the magnetic properties of Co$_x$Pt$_{1-x}$ clusters embedded in various matrices. Using a careful analysis of magnetization curves and ZFC susceptibility...

In the present study, we investigate whether workers close to cities are paid higher non-agricultural wages than workers in outlying rural areas. We find that workers...

By considering an empirical approximation, and a new class of operators that we will call walking operators, we construct, for any positive ND-toeplitz matrix, an...

We show that compact cardinals and {\rm MM} are sensitive to $\lambda$-closed forcings for arbitrarily large $\lambda$. This is done by adding 'regressive'...

In this note we are interested in the modelling of sediment transport phenomena. We mostly focus on bedload transport and we do not consider suspension sediment...

4 pages, 2 figures; To appear in Proceedings of Magnetic Fields in the Universe: From Laboratory and Stars to Primordial Structures Aug. 21st - 27th 2011, Zakopane, Poland Eds....

We study, at the firm level, whether the incremental R&D tax credit increases the private funding of R&D. In order to answer this question, we use the yearly...

We studied the effect of health events (accidents and chronic diseases) on the occupation probabilities at the individual level, while accounting for both correlated...

We have corrected the hypotheses adding an extra symmetry to our class of solutions.

We show two related results on circle diffeomorphisms. The first result is on quasi-reducibility: for a Baire-dense set of $\alpha$, for any diffeomorphism $f$ of...

In this note, I propose the following conjecture~: a finite group G is nilpotent if and only if its largest quotient B-group \beta(G) is nilpotent. I give a proof of...

Ce chapitre traite de la façon dont les acteurs du secteur oléicole palestinien composent avec les restrictions de mobilité. Pour ce faire, il s'agira de revenir tout...

Quantum effects at the nanometric level have been observed in many confined structures, and particularly in semiconductor quantum dots (QDs). In this work, we propose...

Given a finite set $K$, we denote by $X=\Delta(K)$ the set of probabilities on $K$ and by $Z=\Delta_f(X)$ the set of Borel probabilities on $X$ with finite support....
