Truth discovery is a general name for broad range of statistical methods aimed to extract the correct answers questions, based on multiple coming from noisy sources. For example, workers in crowdsourcing platform. In this paper, we consider an extremely simple heuristic estimating workers' competence using average proximity other workers. We prove that estimates well actual level and enables se...

The hypoxia-inducible factor-1 (HIF-1) is the master regulator of the cellular response to hypoxia and its expression levels are tightly controlled through synthesis and degradation. It is widely accepted that HIF-1alpha protein accumulation during hypoxia results from inhibition of its oxygen-dependent degradation by the von Hippel Lindau protein (pVHL) pathway. However, recent data describe n...
