The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Nucleation and growth is the dominant relaxation mechanism driving first-order phase transitions. In two-dimensional flat systems, nucleation has been applied to a wide range of problems in physics, ...

In this paper we study the Tits geometry of a 3-dimensional graph-manifold of nonpositive curvature. In particular we give an optimal upper bound for the length of nonstandard components of the Tits ...
