Enhancing Multi-Distance Phase Retrieval via Unequal Interval Measurements
Photonics, 2021 In the conventional methods of multi-distance phase retrieval, the diffraction intensity patterns are recorded at equal intervals, which can induce slow convergence or stagnation in the subsequent reconstruction process.

Bhattacharyya’s distance measure as a precursor of genetic distance measures
Journal of Biosciences, 2004 In Population Genetics, two populations are distinguished from each other on the basis of the differences in the distributions of the alleles at the locus or loci under consideration. These differences are measured by a “genetic distance” between the two populations (not to be confused with genetic distance between two loci, which is based on ...
