Orphan Annie-eye Nuclei

The nucleus forms the central part of a cell which controls gene expression and mediates the replication of deoxyribonucleic acid (DNA) during cell cycle. Two main types of nuclei which we usually encounter are the open face (transcriptionally active cells), consisting of large areas of euchromatin and the closed faced nucleus (transcriptionally inactive cells-most of its genome is in inactive ...

Brun expansions of stepped surfaces

Dual maps have been introduced as a generalization to higher dimensions of word substitutions and free group morphisms. In this paper, we study the action of these dual maps on particular discrete planes and surfaces – namely stepped planes and stepped surfaces. We show that dual maps can be seen as discretizations of toral automorphisms. We then provide a connection between stepped planes and ...
