The cost of bus travel time variability
… low level of day-to-day travel time variability (TTV). To obtain funds for reducing TTV, it is necessary to give evidence for the benefits from such improvement, but current tools for estimating the cost of TTV are insufficient. This thesis covers issues that arise when analysts need to show that …

TT Virus
… Seren zur Untersuchung der Epidemiologie von TTV zeigte eine Praevalenz von 81% bei Blutspendern, 92.8 bei Intravenoes Drogentoten, 93% bei Prostitierten und und 96.7% bei Homosexuellen. Die signifikant hoehere Durchseuchung aller Risikogruppen im Vergleich zu Blutspendern bestaetigt die …

A transit-timing variation study of the extrasolar planet TrES-3
… of the planet. The transit timing variation (TTV) of each midtime is calculated. Based on these data the presence of a third body in the TrES-3 system cannot be determined. Mass and period of a hypothetical perturbing body are calculated for several illustrative cases.

Einfluss von Immunsuppression auf Hepatitis C-assoziierte Immunphänomene und Hepatitis C-Quasispezies
… zu erkennen, wie eine Rolle von HGV und TTV in der Ätiopathogenese von Autoimmunphänomenen. Kryoglobuline konnten bei einer großen Zahl der Nierentransplantatempfänger nachgewiesen werden. Die Kryoglobulinämie führte zu einem erhöhten Komplementumsatz, hatte aber keinen Einfluss auf die …

Transit timing with fast cameras on large telescopes
… for potential transit timing variations (TTVs) caused by other planets or moons. Our transit midtime analysis contradicts a claimed TTV for OGLE-TR-111b (Diaz et al., 2008), finding no evidence in data from 2005-2009. The radius, 1.019 + 0.026 Rj, is intermediate to previous values (Winn …

Genetic analysis of bacteriophages from clinical and environmental samples
… detected in the CF sputum was Torque Teno virus (TTV). A substantial number of assigned sequences from dairy wastewater could be affiliated with phages of bacteria that are typically found in the soil and aquatic environments, including wastewater. Eukaryotic viral sequences were dominated by …

Characterization of exoplanetary systems combining transit timing techniques and radial velocities: From secular perturbations to resonant chains
… By combining Transit Timing Variations (TTVs) and high-precision Radial Velocity (RV) measurements, I provide crucial constraints on planetary masses, orbits, and system architectures. I first explored tidal orbital decay in ultra-hot Jupiters through the analysis of WASP-12 b, using 12 …

Molecular mechanisms of porcine circovirus 2 replication and pathogenesis
The non-pathogenic porcine circovirus type 1 (PCV1) was originally isolated as a persistent contaminant of the porcine kidney cell line PK-15. Whereas, porcine circovirus type 2 (PCV2) causes postweaning multisystemic wasting syndrome (PMWS) in pigs, which is devastating to the swine industry. My …
