Our calculations confirm that the transit time increases indirect proportional with initial surface charge and proportional with the square thickness.

This study is based on electrocardiogram and respiratory flow data obtained from 3 different subjects during paced breathing at 10 different pacing cycle lengths ranging from 5 s to 12 s. Two different methods ideally suited for the analysis of synchronization pattern of coupled oscillators are applied: 1. Symbolic dynamics based on symbol coding adapted for the detection of respiratory modulation of cardiac parasympathetic activity discloses two regimes of different synchronization behaviour within the frequency area corresponding to the Arnold tongue of 1:1 frequency-locking between respiratory flow and respiratory heartbeat variation (respiratory sinus arrhythmia). 2. The analysis of the phase shift between respiratory flow and respiratory sinus arrhythmia indicates that synchronization is not a static but a dynamic phenomenon. The observed dependence of the phase shift on respiratory cycle length shows large inter-individual variation.

In these devices, pre-fabricated electrodes were coated with a conjugated polymer, which was thus directly exposed to the environment. Oxygen caused an immediate ten-to hundred fold decrease in electroluminescence efficiency relative to that in nitrogen or argon. Above the voltage for light emission, there was a sharp increase in current. Removing the oxygen led to recovery of the light intensity over a period of minutes, but the current returned immediately to its lower, original level. The electroluminescence and photoluminescence spectra were identical and were unaltered in shape by oxygen exposure (only decreasing in size). However, photoluminescence was unaffected by oxygen alone. This result indicates that oxygen does not affect excitons directly, but rather influences an intermediate species on the path to exciton formation, one that is significant only in electroluminescence and not in photoluminescence. Under simultaneous exposure to oxygen and UV light, the photoluminescence irreversibly decreased, presumably due to photo-oxidation}, language = {en} } @article{KrauseWuestneckSeifertetal.1998, author = {Krause, Jens-Peter and W{\"u}stneck, Rainer and Seifert, Arndt and Schwenke, Klaus Dieter}, title = {Relaxation behaviour of spread films and coalescence stability of o/w emulsions formed by succinylated legumin from faba beans (Vicia faba L.)}, issn = {0927-7765}, year = {1998}, language = {en} } @article{SmelaKaminorzInganaesetal.1998, author = {Smela, E. and Kaminorz, Yvette and Ingan{\"a}s, O. and Brehmer, Ludwig}, title = {Planar microfabricated polymer light-emitting diodes}, year = {1998}, abstract = {Conjugated polymers are organic semiconducting materials that can emit light. These polymers have the advantages of being light, cheap, and easy to process, and in addition the band gap can be tailored. We report the microfabrication of surface light emitting diodes (SLEDs) on silicon substrates in which the electrodes are underneath the organic electroluminescent layer. Patterned electrodes are separated by a 2500{\AA}-thick insulating layer of silicon oxide or are interdigitated with a separation of 10 or 20 µm; the luminescent polymer is spin-coated or solvent cast on top of the electrodes. This fabrication method is completely compatible with conventional silicon processing because the polymer is deposited last and the light is emitted from the upper surface of the diodes. Despite the large spacing between electrodes, and despite the absence of an evaporated top contact, the voltages required for light emission were not much greater than those used in conventional sandwich-type structures}, language = {en} } @article{HeuerMenzel1998, author = {Heuer, Axel and Menzel, Ralf}, title = {Phase conjugating SBS-mirror for low powers and reflectivities above 90 \% in an internally tapered optical fiber}, year = {1998}, language = {en} } @article{HeuerHodgsonMenzel1998, author = {Heuer, Axel and Hodgson, N. and Menzel, Ralf}, title = {Efficient, low-threshold phase conjugation in a tapered optical fiber}, year = {1998}, language = {en} } @article{OstermeyerHodgsonMenzel1998, author = {Ostermeyer, Martin and Hodgson, N. and Menzel, Ralf}, title = {High-power, fundamental mode Nd:YALO laser using a phase-conjugate resonator based on SBS}, year = {1998}, language = {en} } @article{FritzSchoenhalsSapichetal.1998, author = {Fritz, A. and Sch{\"o}nhals, A. and Sapich, B. and Rutloh, M. and Stumpe, Joachim}, title = {Dynamical and photochemical behavior of Amorphous copolymers containing photochromic azobenzene side groups}, year = {1998}, language = {en} } @article{VixSapichStumpeetal.1998, author = {Vix, A. and Sapich, B. and Stumpe, Joachim and Stocker, W. and Rabe, J.
