Rotating RAdio Transients are a new class of neutron stars discovered through the emission of radio bursts. Eleven sources are known up to now, but population studies predict these objects to be more numerous than the normal radio pulsar population. Multiwavelength observations of these peculiar objects are in progress to disentangle their spectral energy distribution, and then study in detail ...

Classical game theory struggles to explain how rational players should decide between a number of social conventions, even if some yield higher individual payoffs than others. Thus, on a population level a group or society may be stuck in using one convention when there exist alternative and potentially more beneficial ones. Using an agent-based model the current study examines how convention s...

This article focuses on the estimation of population proportion when the study variable is sensitive in nature. Two implicit randomized response techniques are proposed where the unrelated trait can be chosen subjectively. In addition to unbiased estimation of population proportion and variance, an empirical study is conducted to inspect the relative efficiency facet of the proposed techniques....

Promoting settlement compactness and controlling fragmentation are often discussed as important goals towards sustainability. The article deals with the exploration of 111 urban municipalities in Germany. All cities are compared by characteristics of the urban form and typical statistical facts about cities such as population, employees or buildings. Spatial metrics (e.g. contagion index, core-...
