Figure 2.

Scoring of the energy deposits in the nucleus. The right dashed circle is a magnified view of the small dotted circle on the left with an NP at the center. It represents an ionized NP in the cytoplasm. To score the energy deposits by the electrons from the NPs, each ionized NP is fixed to the origin in the simulation, and the volume of the nucleus, i.e., the volume that has energy deposits scored, is translated accordingly such that the position of the NP relative to the nucleus is kept the same. In the plot, the blue circle represents the boundary of the nucleus.
