Methods We applied different rules to construct binary and weighted networks from EEG and MEG data recorded under a resting-state eyes-open and eyes-closed condition from 21 epilepsy patients and 23 healthy controls. The average shortest path length and the clustering coefficient served as global statistical network characteristics. Results Independent on the behavioral condition, epileptic brains exhibited a more regular functional network structure. Similarly, the eyes-closed condition was characterized by a more regular functional network structure in both groups. The amount of network reorganization due to behavioral state changes was similar in both groups. Consistent findings could be achieved for networks derived from EEG but hardly from MEG recordings, and network construction rules had a rather strong impact on our findings. Conclusions Despite the locality of the investigated processes epileptic brain networks differ in their global characteristics from non-epileptic brain networks. Further methodological developments are necessary to improve the characterization of disturbed and normal functional networks. Significance An increased regularity and a diminished modulation capability appear characteristic of epileptic brain networks.}, language = {en} } @article{LehnertzMormannOsterhageetal.2007, author = {Lehnertz, Klaus and Mormann, Florian and Osterhage, Hannes and Andy, M{\"u}ller and Prusseit, Jens and Chernihovskyi, Anton and Staniek, Matth{\"a}us and Krug, Dieter and Bialonski, Stephan and Elger, Christian E.}, title = {State-of-the-art of seizure prediction}, series = {Journal of Clinical Neurophysiology}, volume = {24}, journal = {Journal of Clinical Neurophysiology}, number = {2}, issn = {1537-1603}, doi = {10.1097/WNP.0b013e3180336f16}, pages = {147 -- 153}, year = {2007}, language = {en} } @article{MuellerVeggianGonoLieder1976, author = {M{\"u}ller-Veggian, Mattea and Gono, Y. and Lieder, R.

The aim of this work is to obtain statistically reliable results concerning optimal surface treatment of scintillation crystals and the selection of reflector material. For this purpose, raw, mechanically polished and etched LSO crystals (size 2×2×10 mm3) were combined with various reflector materials (Teflon tape, Teflon matrix, BaSO4) and exposed to a 22Na source. In order to ensure the statistical reliability of the results, groups of 10 LSO crystals each were measured for all combinations of surface treatment and reflector material. Using no reflector material the light output increased up to 551±35\% by mechanical polishing the surface compared to 100±5\% for raw crystals. Etching the surface increased the light output to 441±29\%. The untreated crystals had an energy resolution of 24.6±4.0\%. By mechanical polishing the surface it was possible to achieve an energy resolution of 13.2±0.8\%, by etching of 14.8±0.7\%. In combination with BaSO4 as reflector material the maximum increase of light output has been established to 932±57\% for mechanically polished and 895±61\% for etched crystals. The combination with BaSO4 also caused the best improvement of the energy resolution up to 11.6±0.2\% for mechanically polished and 12.2±0.3\% for etched crystals. Relating to the light output there was no significant statistical difference between the two surface treatments in combination with BaSO4. In contrast to this, the statistical results of the energy resolution have shown the combination of mechanical polishing and BaSO4 as the optimum.}, language = {en} } @article{LaackRefisch1986, author = {Laack, Walter van and Refisch, A.}, title = {Stellenwert der Kniegelenksarthroskopie aus diagnostischer und therapeutischer Sicht}, series = {Aktuelle Ergebnisse der Osteologie : Timmendorfer Strand, 21. - 23.

There are multiple forms of sterilization, each intended to be applied for a specific target, which depends on—but not limited to—the thermal, physical, and chemical stability of that target. Herein, an overview on the currently used sterilization processes in the global market is provided. Different sterilization techniques are grouped under a category that describes the method of treatment: radiation (gamma, electron beam, X-ray, and ultraviolet), thermal (dry and moist heat), and chemical (ethylene oxide, ozone, chlorine dioxide, and hydrogen peroxide). For each sterilization process, the typical process parameters as defined by regulations and the mode of antimicrobial activity are summarized. Finally, the recommended microorganisms that are used as biological indicators to validate sterilization processes in accordance with the rules that are established by various regulatory agencies are summarized.}, language = {en} }
