A search is reported for a narrow vector resonance decaying to quark-antiquark pairs in proton-proton collisions at root s = 13 TeV, collected with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 2.7 fb(-1). The vector resonance is produced at large transverse momenta, with its decay products merged into a si...
Multivalent glycomaterials show high affinity toward lectins but are often nonselective as they lack the precise 3-D presentation found in native glycans. Here, thiolactone chemistry is exploited to enable the synthesis of glycopolymers with both a primary binding (galactose) and a variable secondary binding unit in close proximity to each other on...
In this paper, we present a non-linear model for the study of DNA denaturation transition. To this end, we assume that the double-strands DNA interact via a realistic generalized Morse potential that reproduces well the features of the real interaction. Using the Transfer Matrix Method, based on the resolution of a Schrödinger equation, we first de...
Avec le changement climatique, les sécheresses et les les incendies de forêts se font plus fréquents et plus sévères. Nous montrons dans cette conférence les effets de ces deux perturbations sur l'environnement. Mais surtout que l'augmentation de la fréquence de chacune d'elle rend la forêt plus sensible à l'autre. Plus que chacune de ces perturbat...
Selon Fontanille (2010), « toute pratique comprend une part d’interprétation, une dimension cognitive interne qui comprendrait toutes les opérations de réglage, de traitement des interactions, qu’elles soient automatiques ou préparées, programmées ou improvisées, volontaires ou involontaires, et qui serait en somme le lieu épi-sémiotique de l’accom...
The interactions between clay-plates and hydrophilic polymer are investigated assuming that the polyethylene glycol chains are grafted onto face-to-face clay-plates. Besides the usual van der Waals attractive interaction, the clay-plates experience a repulsive effective interaction, due to the excluded volume force between monomers along the grafte...
Supramolecular polymeric materials constitute a unique class of materials held together by non-covalent interactions. These dynamic supramolecular interactions can provide unique properties such as a strong decrease in viscosity upon relatively mild heating, as well as self-healing ability. In this study we demonstrate the unique mechanical propert...
