Abstract Two new high-entropy ceramics (HECs) in the weberite and fergusonite structures, along with unexpected formation of ordered pyrochlore phases ultrahigh-entropy compositions an abrupt pyrochlore-weberite transition, are discovered a 21-component oxide system. While Gibbs phase rule allows 21 equilibrium phases, 9 out 13 examined possess single HEC (with ultrahigh ideal configurational e...

Generating and evaluating alternative hypotheses is an essential component of scientific discovery. Evidence from cognitive psychology shows that testing multiple hypotheses, unfortunately, is not effective unless subjects state the hypotheses explicitly. The presence of multiple hypotheses facilitates the efficient elimination of incorrect hypotheses because it makes the possibility of disconf...

In the past five years ‘The Grid’ emerged as one of the most important new developments in building the computing and data management infrastructure for science, business, health, and society in the 21st century. This paper deals with the development and organization of the knowledge discovery processes in Grid environments, especially, with the collaboration and coordination of a set of OGSA b...

Unsupervised part-of-speech induction involves the discovery of syntactic categories in a text, given no additional information other than the text itself. One requirement of an induction system is the ability to handle multiple categories for each word, in order to deal with word sense ambiguity. We construct an algorithm for unsupervised part-of-speech induction, treating the problem as one o...

With the availability of very dense genome-wide maps of markers, multiple testing has become a major difficulty for genetic studies. In this context, the false-discovery rate (FDR) and related criteria are widely used. Here, we propose a finite mixture model to estimate the local FDR (lFDR), the FDR, and the false non-discovery rate (FNR) in variance-component linkage analysis. Our parametric a...
