Cell-matrix contact structures

Cellular and Molecular Life Sciences, 2001
Cell-extracellular matrix contacts are points on cell surfaces where adhesion receptors tether cells to matrix and are linked intracellularly to cytoskeletal components. These structures integrate cell organisation within tissues, support cell motility and specialised activities of differentiated cells, and transduce extracellular signals.

Realistic Metal–Graphene Contact Structures

ACS Nano, 2013
The contact resistance of metal-graphene junctions has been actively explored and exhibited inconsistencies in reported values. The interpretation of these electrical data has been based exclusively on a side-contact model, that is, metal slabs sitting on a pristine graphene sheet.

Contact Structure with Basic Potentials

International Journal of Theoretical Physics, 2005
A contact structure on a manifold \(M\) of odd dimension \(2n+1\) is a 1-form \(\eta\) such that \(\eta \wedge d\eta ^n\) is a volume form. We recall that, in such a case, there exists a unique vector field \(\xi\), called the characteristic (Reeb) vector field, characterized by \(i_\xi \eta=1\) and \(i_\xi d\eta=0\).

Weak Contact Structures

2006
In this paper we investigate weak contact relations C on a lattice L, in particular, the relation between various axioms for contact, and their connection to the algebraic structure of the lattice. Furthermore, we will study a notion of orthogonality which is motivated by a weak contact relation in an inner product space.
