Resonance-enhanced two-photon ionization of He and Xe using a mode-locked Ar+ laser synchronized to VUV synchrotron radiation pulses

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

Spectroscopic techniques using synchrotron radiation and free-electron and conventional lasers

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

Circulation of Knowledge : Explorations in the History of Knowledge

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

Long-term Safety and Efficacy of Reslizumab in Patients with Eosinophilic Asthma

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

Reduced order modelling of elastomeric vibration isolators in dynamic substructuring

Dynamic substructuring is often employed to reduce the size of numerical models for structural dynamic analysis. In this paper, we discuss how elastomeric vibration isolators can be modelled within the framework of dynamic substructuring in order to obtain accurate and efficient reduced order models. For several reasons, it is beneficial to divide a structure containing elastomeric isolators into
