Conway irreducible hyperbolic knots with two common covers
2005
International audience; For each pair of coprime integers n > m ≥ 2 we construct pairs of non equivalent Conway irreducible hyperbolic knots with the same n-fold and m-fold cyclic branched covers.

High-resolution infrared spectroscopy and analysis of the v2=v4 bending dyad and v3 stretching fundamental of ruthenium tetroxide
2017
International audience; RuO4 is a heavy tetrahedral molecule which has practical uses for several industrial fields. Due to its chemicaltoxicity and the radiological impact of its 103 and 106 isotopologues, the possible remote sensing of this compound in theatmosphere has renewed interest in its spectroscopic properties. We investigate here for the first time at high resolutionthe bending dyad region in the far IR and the line intensities in the 3 stretching region. Firstly, new high resolutionFTIR spectra of the bending modes region in the far infrared have been recorded at room temperature, using a speciallyconstructed cell and an isotopically pure sample of 102RuO4. New assignments and e…
Theoretical principles of near-field optical microscopies and spectroscopies
2000
International audience; This paper deals with the principles of detection of optical signals near a surface in a manner permitting the mapping of the distribution of the fields close to various kinds of illuminated samples. We begin with a discussion of the main physical properties of the optical fields near a surface in the absence of any probe tip. This mainly concerns phenomena involving evanescent waves for which the local decay lengths are governed not only by the sizes but also by the intrinsic properties of the surface structures. The interpretation of the detection process is reviewed on the basis of a discussion about the possibility of establishing direct comparisons between exper…

Identification et caractérisation du récepteur à la flagelline (VvFLS2) et recherche du récepteur aux chito-oligosaccharides chez la vigne
2014
Pattern-recognition receptors (PRRs) play a key role in plant immunity by assuring recognition of microbe-associated molecular patterns (MAMPs), signature of microbial presence. MAMP perception constitutes the first layer of pathogen detection and activates defense mechanisms that aim to block the intruder. This study brings an insight into how grapevine (Vitis vinifera) perceives two MAMPs: the flagellin-derived flg22 peptide and chitin, which are conserved motifs occurring over the whole bacterial and fungal classes, respectively. This study analyzed MAMP-triggered early signaling events, defense gene expression and also the efficiency of elicited defense against gray mold and downy milde…
