The congenital hamartomatous syndrome known as the "Proteus syndrome" (PS) manifests itself with regional giantism, lymphangiomatous hamartomas, and other variable features. Review of the medical literature shows approximately 50 cases reported to date. Since this syndrome has only recently been defined, the management of these patients has been speculative(More)
A considerable distinction of light-induced scattering in optically biaxial crystals comes from the fact that the principal axes of the optical indicatrix do not coincide with the crystallographic directions. The study of photorefractive scattering in Sn2P2S6 (monoclinic symmetry) revealed the particular requirements as to light polarization for excitation(More)
Processes of photo-induced light scattering are studied in single crystals of LiNbO(3):Fe to uncover the origin of a new part of the entire scattering pattern which can be observed on a viewing screen. The new scattering manifests itself as two arcs enclosing the directly transmitting pump beam. It is shown that this type of scattering is due to a(More)
The electrical power consumption of current supercomputers has become the key limiting factor to successfully reach exascale. To further increase energy efficiency, the use of mobile system-on-chips (SoCs) has been proposed in the past. In this work we investigate four development boards equipped with different SoCs with respect to their suitability for(More)
Electric arc furnace dust (EAFD) is a major issue for processing technologies: Several million tons per year are generated, it contains both valuable and hazardous metals and yet no available treatment process has proven to be superior to all others. Processes currently applied or being developed are either of hydro- or pyrometallurgical type, which are(More)
Permanently fixed noisily recorded refractive index gratings are discovered in single crystals of LiNbO(3):Fe upon long-term exposure to a single laser beam with high intensities of I=100 kW/m(2) and ambient temperature. The fixing process is explained by considering the effect of laser-induced heating of the sample and the well-known simultaneous thermal(More)
