We studied the role of active deformation dynamics in cell nuclei in chromatin positioning. Model chains containing two types of regions, with high (euchromatic) or low (heterochromatic) mobility, were confined in a pulsating container simulating a nucleus showing dynamic deformations. Brownian dynamic simulations show that the positioning of low mobility regions changes from sites near the per...

Positioning is a fundamental problem in mobile robot navigation. Several approaches to cope with the dynamic positioning problem have been made. Most of them are based on the inconsistent use of the algorithm for static positioning enhanced by predictive algorithms. In this paper, a method that guarantees the consistent use of this algorithm at any time under dynamic condition is presented. It ...
