Multispecies coalescent(MSC) is the extension of the single-population coalescent model to multiple species. It integrates the phylogenetic process of species divergences and the population genetic process of coalescent, and provides a powerful framework for a number of inference problems using genomic sequence data from multiple species, including estimation of species divergence times and population sizes,estimation of species trees accommodating discordant gene trees, inference of cross-species gene flow and species delimitation. In this review, we introduce the major features of the MSC model, discuss full-likelihood and heuristic methods of species tree estimation and summarize recent methodological advances in inference of cross-species gene flow. We discuss the statistical and computational challenges in the field and research directions where breakthroughs may be likely in the next few years.

＜正＞ In this study, corn stover was liquefied in acidic conditions, and several polymer materials were subsequently prepared from the liquefied mass. The effectual solvent for the liquefaction process was selected, and the influence of various liquefaction conditions was also investigated. The polyols from the liquefaction were then separated and purified through a series of processes, such as dilution, pH adjustment, filtration, evaporation and ozonolysis. Processes for

In the present work,we report the growth of all-inorganic perovskite nanorings with dual compositional phases of CsPbBr_(3)and CsPb_(2)Br5 via a facile hot injection *** self-coiling of CsPbBr_(3)-CsPb_(2)Br5 nanorings is driven by the axial stress generated on the outside surface of the as-synthesized nanobelts,which results from the lattice mismatch during the transformation of CsPbBr_(3)to CsPb_(2)*** tailored growth of nanorings could be achieved by adjusting the key experimental parameters such as reaction temperature,reaction time and stirring speed during the cooling *** photoluminescence intensity and quantum yield of nanorings are higher than those of CsPbBr_(3)nanobelts,accompanied by a narrower full width at half maximum(FWHM),suggesting their high potential for constructing self-assembled optoelectronic nanodevices.
