Self-Centering in Cytoplasmic Fragments of Melanophores [PDF]
Molecular Biology of the Cell, 1998 The radial array of cytoplasmic microtubules (MTs) provides routes for intracellular transport and defines spatial organization of cytoplasm through interaction with molecular motors bound to membrane organelles (Kellogg et al., 1994 ; Hirokawa, 1998 ). The array is believed to be organized by the centrosome, which is capable of nucleating MTs.

A characterization for 2-self-centered graphs
Discussiones Mathematicae Graph Theory, 2018 A Graph is called 2-self-centered if its diameter and radius both equal to 2. In this paper, we begin characterizing these graphs by characterizing edge-maximal 2-self-centered graphs via their complements. Then we split characterizing edge-minimal 2-self-centered graphs into two cases. First, we characterize edge-minimal 2-self-centered graphs without
