Walk entropies on graphs [PDF]
Entropies based on walks on graphs and on their line-graphs are defined. They are based on the summation over diagonal and off-diagonal elements of the thermal Green’s function of a graph also known as the communicability. The walk entropies are strongly

Characterization of Line-Consistent Signed Graphs
The line graph of a graph with signed edges carries vertex signs. A vertex-signed graph is consistent if every circle (cycle, circuit) has positive vertex-sign product. Acharya, Acharya, and Sinha recently characterized line-consistent signed graphs, i.e.

Graphs isomorphic to subgraphs of their line-graphs
AbstractAn embedding of graph G into graph H is by defenition an isomorphism of G onto a subgraph of H. It is shown in this paper that every unicycle U embeds in its line-graph L(U), and that every other connected graph that embeds in its own line-graph may be constructed from such an embedded unicycle in a natural way.

Graph equations for line graphs and total graphs
AbstractAll pairs (G,H) of graphs G,H satisfying L(G) = T(H) are determined. The “graph equation“ L(G)= T(H) is also solved.

Some Properties of Regular Line Graphs
In this paper, the concept of regular line graph has been introduced. The maximum number of vertices with different degrees in the regular line graphs has also been studied.

Drawing Arrangement Graphs In Small Grids, Or How To Play Planarity [PDF]
We describe a linear-time algorithm that finds a planar drawing of every graph of a simple line or pseudoline arrangement within a grid of area O(n^{7/6}). No known input causes our algorithm to use area \Omega(n^{1+\epsilon}) for any \epsilon>0; finding

On the line-connectivity of line-graphs
Throughout the paper, G will denote a finite undirected graph without loops or multiple lines. The line-graph L(G) of G is that graph whose point set can be put in one-to-one correspondence with the line set of G, such that two points of L(G) are adjacent if and only if the corresponding lines of G are adjacent.

On Hamilton Decompositions of Line Graphs of Non-Hamiltonian Graphs and Graphs without Separating Transitions [PDF]
In contrast with Kotzig's result that the line graph of a $3$-regular graph $X$ is Hamilton decomposable if and only if $X$ is Hamiltonian, we show that for each integer $k\geq 4$ there exists a simple non-Hamiltonian $k$-regular graph whose line graph ...

On two energy-like invariants of line graphs and related graph operations
For a simple graph G of order n, let μ 1 ≥ μ 2 ≥ ⋯ ≥ μ n = 0 $\mu_{1}\geq\mu_{2}\geq\cdots\geq\mu_{n}=0$ be its Laplacian eigenvalues, and let q 1 ≥ q 2 ≥ ⋯ ≥ q n ≥ 0 $q_{1}\geq q_{2}\geq\cdots\geq q_{n}\geq0$ be its signless Laplacian eigenvalues.

FoxO1 signaling in B cell malignancies and its therapeutic targeting
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.
