In the presence of recombination and gene conversion, a given genomic segment may inherit information from 2 distinct immediate ancestors. The importance of this type of molecular inheritance has become increasingly clear over the years, and the potential for erroneous inference when it is not accounted for in the statistical model is well documented. Yet, the inclusion of plural ancestry (PA) ...

Mating types of the fission yeast Schizosaccharomyces pombe interchange nonrandomly in a cell lineage so that only one cell among four granddaughters of a cell ever switches, and the sister of the newly switched cell switches efficiently in consecutive cell divisions, thereby producing chains of recurrent switching. The programme of cellular differentiation is mediated by inheritance of parenta...

Dither signals are commonly used in electronics for implementing different type of modulations in power converters, which represent a very interesting class of hybrid systems. It was recently shown that a nonsmooth dithered system can be approximated by an averaged system provided that the dither frequency is sufficiently high and that the amplitude distribution function of the dither is absolu...
