Serum-free media studies of human embryonic stem cell culture on microcarriers by Chen, Xiaoli.

“…The 2 key properties of human embryonic stem cells (hESC), namely pluripotency and unlimited self-renewal, give them a great potential in the area of stem cell research and applications in cell therapy. It has been shown that human embryonic stem cells (hESC) can be grown and maintained on microcarriers using both defined, serum-free media, and MEF-CM. …”

Free fermion six vertex model: symmetric functions and random domino tilings by Aggarwal, Amol, Borodin, Alexei, Petrov, Leonid, Wheeler, Michael

“…Abstract Our work deals with symmetric rational functions and probabilistic models based on the fully inhomogeneous six vertex (ice type) model satisfying the free fermion condition. Two families of symmetric rational functions $$F_\lambda ,G_\lambda $$ F λ , G λ are defined as certain partition functions of the six vertex model, with variables corresponding to row rapidities, and the labeling signatures $$\lambda =(\lambda _1\ge \ldots \ge \lambda _N)\in {\mathbb {Z}}^N$$ λ = ( λ 1 ≥ … ≥ λ N ) ∈ Z N encoding boundary conditions. …”
