People tend to have various opinions about topics. In discussions, they can either agree or disagree with another person. The recognition of agreement and disagreement is a useful prerequisite for many applications. It could be used by political scientists to measure how controversial political issues are, or help a company to analyze how well people like(More)
On day 2 after delivery, dams of the DBA/1 mouse inbred strain (n = 20/group) with their litter were allocated to one of the following groups: NH21, nonhandling, housed 1 litter/cage, weaned on postnatal day (PND) 21;H21, handling, housed 1 litter/cage, weaned on PND 21; NH30, nonhandling, group-housed (5 litters/cage), weaned on PND 30; H30, handling,(More)
C57BL/6 mice were intubated on gestational days 14-18 twice daily with 1.58 g/kg ethanol, 4.2 g/kg sucrose, or remained untreated. Offspring of ethanol-treated or lab chow control groups were raised either by group-housed dams and weaned on postnatal day (PND) 28 (enriched condition), or by individually housed dams and weaned on PND 21 (standard condition).(More)

We present an approach and mobile application for the interactive exploration and search of geo-located social media entities from different, distributed data providers on the web. When querying the providers, the returned results typically have some overlap. In addition, one has no guarantee that the providers reply within a given time interval. Thus, in(More)
When querying data providers on the web, one has no guarantee that they will reply within a given time. Some providers may even not answer at all. This makes it infeasible to wait for a complete result before beginning with the entity resolution. In order to solve this problem , we present a query-time entity resolution approach that takes the asynchronous(More)
Commercial apps for nearby search on mobile phones such as Qype, AroundMe, Foursquare, or Wikitude have gained huge popularity among smartphone users. Understanding the way how people use and interact with such applications is fundamental for improving the functionality and the user interface design. In our two-step field study, we developed and evaluated(More)
The effects of preweaning experience in rats and mice on neuroendocrine and behavioral end points and their implications for prenatal drug effects are reviewed. The hypothalamo-pituitary-adrenal axis and the dopaminergic system were shown to be affected. Behavior related to hippocampal, adrenocortical functions and to the benzodiazepine receptor system was(More)
