Effect of Nanoparticle Rigidity on the Interaction of Stromal Membrane Particles with Leukemia Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Cell membrane nanoparticles made with stromal cells are prepared and used to target leukemia cells. Deposition of the cell membrane onto rigid silica cores leads to increased uptake both in leukemia cell lines and primary cells from patients. These results show that nanoparticle rigidity affects the interaction between cell membrane nanoparticles and ...

The optimal general upper bound for the distinguishing index of infinite graphs

Journal of Graph Theory, 2019
The distinguishing index D′(G) of a graph G is the least cardinal number d such that G has an edge‐coloring with d colors, which is preserved only by the trivial automorphism.

Infinite quantum graphs

Doklady Mathematics, 2017
Infinite quantum graphs with δ-interactions at vertices are studied without any assumptions on the lengths of edges of the underlying metric graphs. A connection between spectral properties of a quantum graph and a certain discrete Laplacian given on a graph with infinitely many vertices and edges is established.

A copositive formulation for the stability number of infinite graphs

Mathematical programming, 2013
In the last decade, copositive formulations have been proposed for a variety of combinatorial optimization problems, for example the stability number (independence number).
