The noble gases are the most inert group of the periodic table, but their reactivity increases with pressure. Diamond-anvil-cell experiments and ab initio modelling have been used to investigate a possible direct reaction between xenon and oxygen at high pressures. We have now synthesized two oxides below 100 GPa (Xe2O5 under oxygen-rich conditions, and Xe3O2 under oxygen-poor conditions), whic...

Nowadays, social networks have become an ideal tool for sharing information in real time. Different type of users use social media to comment about their activities, opinions, personal views, etc. The information poured in this media has become of particular interest to online reputation analysts, for instance, to identify relevant tendencies. 133 Research in Computing Science 115 (2016) pp. 13...

This paper presents a printed near field communication system that can be integrated into everyday objects, like paper products or plastic parts. The interface is realised by high-volume production technologies, like printing and injection moulding, as they allow for the integration of “low-end” electronics at low costs and, thus, potentially enable a wide spreading of the technology. As a firs...

2008. Is spread of invasive species regulated? Using ecological theory to interpret statistical analysis. Appendix A. Technical note on testing random walk hypotheses, derivation of dynamics under "spread regulation" of new-site ratios, models used for simulated spread scenarios, and mathematical approximation showing approximate "spread regulation" expected slope of-1. A1. Statistical testing ...

Noninvasive measurements of regional cerebral blood flow (rCBF), using the Xe-133 clearance technique and a two-compartment open model for data analysis, may produce false numerical results when distinction between compartments is poor. For rapid detection of error conditions of that kind, we propose a three-dimensional graphic display of the quality of fit to the original clearance curve, base...

The vibrational spectra of H(2)SO(4)/H(2)O vapors trapped in solid Xe are reported and the spectral shifts are compared to the analogous spectra in argon matrices. In the same matrix layer the nu(OH) stretches of highly acidic species (H(2)SO(4) and H(2)SO(4)*H(2)O) show distinctly larger red shifts as opposed to species of lower acidity or to modes which do not involve directly the O-H bond. A...

Measurements of relative dielectronic recombination (DR) cross sections for Auorinelike xenon {Xe +) are presented. Recombination takes place in an electron-beam ion trap, where decay rates are obtained as the ions recombine with beam electrons. Experimental data are obtained by counting the number of ions that remain, as a function of time, following the recombination period. The counting is a...

Xenon is one of noble gases and has been recognized as an anesthetic for more than 50 years. Xenon possesses many of the characteristics of an ideal anesthetic, but it is not widely applied in clinical practice mainly because of its high cost. In recent years, numerous studies have demonstrated that xenon as an anesthetic can exert neuroprotective and cardioprotective effects in different model...
