Gibberellic acid (GA) promotes seed germination, elongation growth, and flowering time in plants. GA responses are repressed by DELLA proteins, which contain an N-terminal DELLA domain essential for GA-dependent proteasomal degradation of DELLA repressors. Mutations of or within the DELLA domain of DELLA repressors have been described for species including(More)
Acknowledgment I'd like to thank my supervisor Prof. Dr.-Ing. Elmar Nöth who supported me throughout this work. It would not have been possible to complete this thesis without his support and his valuable comments on my algorithms and this manuscript. During my stay in Japan, I had the opportunity to visit the lab of Prof. Sadaoki Furui (Ph. D.). Shortly(More)
Normally, mobile pedestrian navigation systems use visually perceptible landmarks to guide their users through the environment. In this article we introduce concepts for the use of auditory perceptible landmarks in route descriptions. Such auditory perceptible landmarks complement their visual counterparts and also stand to be beneficial for certain groups(More)
Mit neuen Technologien entstehen auch neue Interaktionskonzepte. Beispiels-weise kann man eine Telefonnummer mittlerweile durch das Drehen einer Wählscheibe (wer erinnert sich noch?), dem Drücken der Tasten des Num-mernblocks, aber auch mittels Touchdisplay, Sprach-oder Gestens-teuerung eingeben. Doch welche dieser Varianten ist die beste? Und wo genau(More)
Ensemble and single-molecule spectroscopy demonstrates that both emission and absorption of peridinin-chlorophyll-protein photosynthetic antennae can be largely enhanced through plasmonic interactions. We find up to 18-fold increase of the chlorophyll fluorescence for complexes placed near a silver metal layer. This enhancement, which leaves no measurable(More)
Today, the demand for software that is 'intuitive to use' is very high. In fact, this has become a determining factor for the success of a system. However, building software that is intuitive to use is challenging. This is particularly true for small and medium-sized enterprises (SMEs). They have to face a variety of problems to remain competitive: Usually(More)
To investigate the influence of chronic hypoxia and anoxia on cell survival after low- and high-LET radiation, CHO-K1 cells were kept for 24 h under chronic hypoxia (94.5% N2; 5% CO2; 0.5% O2) or chronic anoxia (95% N2; 5% CO2). Irradiation was performed using 250 kVp X-rays or carbon ions with a dose average LET of 100 keV/μm either directly under the(More)
