A Spectral Characterization of the S-Clique Extension of the Triangular Graphs
Discussiones Mathematicae Graph Theory, 2020 A regular graph is co-edge regular if there exists a constant µ such that any two distinct and non-adjacent vertices have exactly µ common neighbors. In this paper, we show that for integers s ≥ 2 and n large enough, any co-edge-regular graph which is ...

Journal of Combinatorial Theory, Series B, 1971 AbstractThis paper is a continuation of [1] and we shall use the same terminology. The main result of this part is the following: Suppose that the automorphism group of a connected graph of valency p + 1, p a prime, has a subgroup which acts as a regular permutation group on the set of s-arcs of the graph. Then s ≤ 7 and s ≠ 6.

Hamiltonian Strongly Regular Graphs [PDF]
SSRN Electronic Journal, 2008 We give a sufficient condition for a distance-regular graph to be Hamiltonian. In particular, the Petersen graph is the only connected non-Hamiltonian strongly regular graph on fewer than 99 vertices.

The matching polynomial of a distance-regular graph
International Journal of Mathematics and Mathematical Sciences, 2000 A distance-regular graph of diameter d has 2d intersection numbers that determine many properties of graph (e.g., its spectrum). We show that the first six coefficients of the matching polynomial of a distance-regular graph can also be determined from ...

Electronic Journal of Graph Theory and Applications, 2015 We study a family of graphs related to the $n$-cube. The middle cube graph of parameter k is the subgraph of $Q_{2k-1}$ induced by the set of vertices whose binary representation has either $k-1$ or $k$ number of ones.

On endomorphism-regularity of (n, n + 1)-graphs
AKCE International Journal of Graphs and CombinatoricsThe aim of this paper is to investigate End-regularity of [Formula: see text]-graphs which are connected graphs with [Formula: see text] vertices and [Formula: see text] edges.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells
Molecular Oncology, EarlyView.Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...
