It has been believed that XIST RNA requires a discrete window in early development to initiate the series of chromatin-remodeling events that form the heterochromatic inactive X chromosome. Here we investigate four adult male HT-1080 fibrosarcoma cell lines expressing ectopic human XIST and demonstrate that these postdifferentiation cells can undergo chromosomal inactivation outside of any norm...

Rapid interphase chromosome territory repositioning appears to function through the action of nuclear myosin and actin, in a nuclear motor complex. We have found that chromosome repositioning when cells leave the cell cycle is not apparent in cells that have mutant lamin A or that are lacking emerin. We discuss the possibility that there is a functional intranuclear complex comprising four prot...

This chapter addresses the topic of \splines on surfaces", an area of spline theory concerned with the construction of functions deened on manifolds in the three-dimensional Euclidean space. For the most part, the mathematical aspects of this discipline are an unchartered territory and therefore much of what we will say here will have an exploratory character.

– The aim of this paper is the presentation of an approach of firms-territories relationships in terms of firms' nomadism and territorial anchorage of technological and industrial activities. Such an approach is founded on the necessity to overcome the “volatile” firm's level of analysis, in which firm's mobility is investigated from the sole point of view of the leaven location. On the contrar...

In augmented reality (AR) environments, users experience the physical environment and other users directly along with mediated virtual objects embedded in the environment. In immersive virtual reality (VR), users experience of a visual environment (and sometimes other senses) is completely mediated. The representation of user’s body in virtual environments granted us a new research territory in...
