Local well-posedness and low Mach number limit of the compressible magnetohydrodynamic equations in critical spaces [PDF]
Kinet. Relat. Models 10 (2017), no. 3, 741--784, 2014 The local well-posedness and low Mach number limit are considered for the multi-dimensional isentropic compressible viscous magnetohydrodynamic equations in critical spaces. First the local well-posedness of solution to the viscous magnetohydrodynamic equations with large initial data is established.

Study of a New Asymptotic Preserving Scheme for the Euler System in the Low Mach Number Limit
SIAM Journal on Scientific Computing, 2017 This article deals with the discretization of the compressible Euler system for all Mach numbers regimes. For highly subsonic flows, since acoustic waves are very fast compared to the velocity of the fluid, the gas can be considered as incompressible ...

Pedigree reconstruction for triploid apple cultivars using single nucleotide polymorphism array data
PLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 98-111, January 2023., 2023 Many economically, culturally, and historically important apple cultivars are triploids, which have three copies of each chromosome instead of the more typical two copies in diploids. Despite their prevalence and importance, there have been conflicting reports regarding their origin and their ability to beget diploids.
