Behavioural isolation from divergence in male advertisement calls and female preferences is hypothesized to cause genetic divergence and speciation in the Amazonian frogs Physalaemus petersi and P. freibergi, yet the importance of call variation and landscape features in genetic divergence is unresolved. We tested for correlations between genetic divergence at microsatellite loci and (1) call v...

aims: although several studies have confirmed the validity and the strength of the student-centered approach and most training centeres have put it as the heading of their agenda, there are still problems in the method of implementation, increasing the need for further research to review the mode of implementation. in this regard, the present study has been conducted to investigate students’ an...

Abstract There are three classical divergence measures exist in the literature on information theory and statistics. These are namely, Jeffryes-Kullback-Leiber [6], [8] J-divergence. SibsonBurbea-Rao [9], [3] Jensen-Shannon divegernce and Taneja [11] Arithmetic-Geometric divergence. These three measures bear an interesting relationship among each other. The divergence measures like Hellinger [5...

In this paper we analyze the approximation of stable linear time-invariant systems, like the Hilbert transform, by sampling series for bandlimited functions in the Paley–Wiener space PW π . It is known that there exist systems and functions such that the approximation process is weakly divergent, i.e., divergent for certain subsequences. Here we strengthen this result by proving strong divergen...

In this paper, we extend the concept of classical f -divergence (for a pair of measures) to mixed f -divergence (for multiple pairs of measures). Mixed f -divergence provides a way to measure the difference between multiple pairs of probability distributions. Properties for mixed f -divergence are established, such as permutation invariance and symmetry in distributions. We also provide an Alex...

For more than 30 years, expression divergence has been considered as a major reason for retaining duplicated genes in a genome, but how often and how fast duplicate genes diverge in expression has not been studied at the genomic level. Using yeast microarray data, we show that expression divergence between duplicate genes is significantly correlated with their synonymous divergence (K(S)) and a...
