The fluorescence emission following inner-shell excitation of molecules has been analyzed in the wavelength region 300 nm≤λfluo≤1000 nm. The main contributions to the experimental spectrum are due to transitions of the parent molecules ionized in the outer valence shells as well as to the radiative decay of excited photofragments, mainly neutral and singly charged atoms. As an example, the dispers
The technique of synchronization between the pulses of a linear dye laser, synchronously pumped by a mode-locked Ar+ laser, and the synchrotron radiation pulses from the SuperACO storage ring in Orsay (France) has been applied to study the photoionization of the Xe* 5p55d [3/2]1 and Xe* 5p56d [3/2]1 excited states in the energy region between the Xe+ 5p5(2P3/2) and (2P1/2) thresholds. The experime
The light pulses of a mode-locked Ar+ laser have been synchronized to the synchrotron radiation pulses of the SuperACO storage ring in Orsay. In order to test the feasibility and to demonstrate the capability for the investigation of free atoms we have studied the two-photon ionization of atomic Helium and Xenon via the He* 1s3p and Xe* 5p55d resonant state, respectively. The experimental results
Considerable progress in the investigation of the electronic and vibrational properties of atoms, molecules, materials, surfaces and interfaces has been achieved by combining different photon sources of complementary characteristics. In this paper some experimental results obtained recently at LURE by using two synchronized sources, such as the IR free-electron laser (FEL) CLIO, the VUV storage ri
Historians have long been interested in knowledge—its nature and origin, and the circumstances under which it was created—but it has only been in recent years that the history of knowledge has emerged as an academic field in its own right.In "Circulation of Knowledge", a group of Nordic scholars explore a range of theoretical and methodological approaches to this new and exciting area of histori

Background In placebo-controlled trials, reslizumab, an anti-IL-5 monoclonal antibody, significantly reduced asthma exacerbations and improved lung function and asthma control in patients with eosinophilic asthma. Objective This open-label extension study evaluated safety and efficacy of reslizumab for up to 24 months. Methods After participation in 1 of 3 placebo-controlled, phase III trials in m
