Patent trolls—firms that appropriate profits from innovation by enforcing patents against infringers—are peculiar players on markets for technologies. As buyers of patents, they are solely interested in the exclusion right, not in the underlying knowledge. Similarly, when they sell or license out patents, the transaction does not involve a technology(More)
It has recently been shown that adenosine-5′-triphosphate (ATP) is released together with glutamate from sensory axons in the olfactory bulb, where it stimulates calcium signaling in glial cells, while responses in identified neurons to ATP have not been recorded in the olfactory bulb yet. We used photolysis of caged ATP to elicit a rapid rise in ATP and(More)

The Parapoxvirus Orf virus represents a promising candidate for novel vector vaccines due to its immune modulating properties even in nonpermissive hosts such as mouse or rat. The highly attenuated Orf virus strain D1701 was used to generate a recombinant virus (D1701-VrVp40) expressing nucleoprotein p40 of Borna disease virus, which represents a major(More)
In this paper, we present a mechanism on a non-monetary level that achieves Pareto-efficient bandwidth allocation in a network. Monetary mechanisms, known as congestion pricing, are subject to implementation issues and opposed by conceptional questions in a scenario on end user level. Therefore we conducted our research in the field of non-monetary(More)
Borna disease virus (BDV) can persistently infect the central nervous system and induce CD8+ T-cell-mediated neurological disease in MRL mice. To determine whether specific immune priming would prevent disease, a prime-boost immunization protocol was established in which intramuscular injection of a recombinant parapoxvirus expressing BDV nucleoprotein(More)
Economic analysis of WiMAX business models under the German legal framework shows that high overbooking rates are essential for establishing profitable business models. In this paper, we analyse different incentive systems that affect users to reduce bandwidth consumption in congestion periods in order to permit an increase of the overbooking rate. At first(More)
