Coevolutionary arms races between brood parasites and hosts provide tractable systems for understanding antagonistic coevolution in nature; however, little is known about the fate of frontline antiparasite defenses when the host “wins” the coevol

Au même titre que l'ancien royaume des Asturies en Espagne, que le pays de Galles en Angleterre et que le Dauphiné en France, le comté de Charollais fut, sous le gouvernement des ducs Valois de Bourgogne, l'apanage personnel de l'héritier présom

Implantations of 59Co ions into nickel films at energies between 150 and 1000 keV have been performed. Cobalt depth profiles are measured by secondary ion mass spectrometry. The influence of oxygen flooding on the development of surface roughness has

In order for hot-wire chemical vapor deposition to compete with the conventional plasma-enhanced chemical vapor deposition technique for the deposition of microcrystalline silicon, a number of key scientific problems should be cleared up. Among these

The chemical durability of crystalline matrices loaded with actinides can be stronglyreduced when α-decays generate enough disorder to induce a crystalline to amorphoustransition. The alpha decay of actinides in SrTiO3 (α-recoils and α-particles)

In fluoroapatite, the α-annealing is a crystal recovery process due to the electronic energy loss of α-particles emitted by radionuclides. This effect, which can be accompanied by a thermal recovery, is accounting for the crystalline state of natur

Damage creation in crystalline α-quartz by irradiation is studied using gold ions of energies between 0.5 and 10 MeV. For all ions, the total stopping power (dE/dx)tot has a value of about 4.5 keV/nm, whereas the contribution of the electronic stopp

Damage creation in crystalline α -quartz under gold irradiation was studied at 1.0 and 5.5 MeV using the ARAMIS accelerator at CSNSM (Orsay). Although at these energies the total stopping powers are nearly equal (respectively, 4.20 and 4.46 keV nm
