Asymmetry

Hepatocyte–sinusoid alignment (HSA) causes asymmetric shapes in early hepatocellular tumors. Introduction The mammalian liver is subdivided into lobes and further into thousands of hexagonal columns, called lobules, which act in parallel.

Waves produced by an excitable FitzHugh–Nagumo PDE. Introduction We will here take a closer look at waves produced by an excitable FitzHugh–Nagumo PDE in a periodic 1D domain, in a periodic 2D domain.
