Let G = (V,E) be a graph. By directional labeling (or d-labeling) of an edge x = uv of G by an ordered n-tuple (a1, a2, · · · , an), we mean a labeling of the edge x such that we consider the label on uv as (a1, a2, · · · , an) in the direction from u to v, and the label on x as (an, an−1, · · · , a1) in the direction from v to u. In this survey, we study graphs, called (n, d)-sigraphs, in whic...
We conjecture that every signed graph of unbalanced girth 2g, whose underlying graph is bipartite and planar, admits a homomorphism to the signed projective cube of dimension 2g−1. Our main result is to show that for a given g, this conjecture is equivalent to the corresponding case (k = 2g) of a conjecture of Seymour claiming that every planar k-regular multigraph with no odd edge-cut of less ...
Each family of signal transduction systems requires specificity determinants that link individual signals to the correct regulatory output. In Bacillus subtilis, a family of four anti-terminator proteins controls the expression of genes for the utilisation of alternative sugars. These regulatory systems contain the anti-terminator proteins and a RNA structure, the RNA anti-terminator (RAT) that...
