Large scale traffic congestion often stems from local traffic jam in single road or intersection. In this paper, macroscopic method was used to explore the formation and propagation of local traffic jam. It is found that (1) the propagation of traffic jam can be seen as the propagation of traffic signal parameters, that is, virtual split and virtual green time; (2) for a road with endogenous fl...

p. (x) l. 5, “Chapter 4” should read “Chapter 6”. p. 24–25: As it stands, the proof of Lemma 2.2.3 is wrong, because ψ is not necessarily surjective. However, if P is a finitely generated projective module, then the proof works. So at the beginning of the section, one should make the further observation that P = F ′(ΓΓ) is a finitely generated projective module. This is because among all projec...

Background Each year breast cancer is diagnosed in approximately 1 million women worldwide [1]. Our lab has previously linked Junctional Adhesion Molecule A (JAM-A) gene and protein over-expression in breast tumours with an increased risk of metastasis [2,3]. JAM-A loss or inhibition has also been shown to inhibit cell migration and invasion [2], while increasing apoptosis possibly as a result ...

The junctional adhesion molecule B (JAM-B) is a multifunctional transmembrane protein, which belongs to the immunoglobulin superfamily (IgSF). JAM-B is localized to cell-cell contacts and enriched at cell junctions in epithelial and endothelial cells, as well as on the surface of erythrocytes, leukocytes, and platelets. Recent research in this field has shown that JAM-B plays an important role ...

A detailed study is undertaken of the v{max}=1 limit of the cellular automaton traffic model proposed by Nagel and Paczuski [Phys. Rev. E 51, 2909 (1995)]. The model allows one to analyze the behavior of a traffic jam initiated in an otherwise freely flowing stream of traffic. By mapping onto a discrete-time queueing system, itself related to various problems encountered in lattice combinatoric...
