Distinguishing number of vertex-transitive graphs of valency 4 [PDF]
, 2019 Apart from finitely many exceptions, connected vertex-transitive graphs of valency at most 3 have distinguishing number 2. Recently, Florian Lehner and I determined the distinguishing number of all vertex-transitive graphs of valency 4.

General Vertex-Distinguishing Total Colorings of Complete Bipartite Graphs
MathematicsLet G be a simple graph. A general total coloring f of G refers to a coloring of the vertices and edges of G. Let C(x) be the set of colors of vertex x and edges incident with x under f. For a general total coloring f of G in which k colors are available,

On Computing the Distinguishing Numbers of Trees and Forests [PDF]
The Electronic Journal of Combinatorics, 2006 Let $G$ be a graph. A vertex labeling of $G$ is distinguishing if the only label-preserving automorphism of $G$ is the identity map. The distinguishing number of $G$, $D(G)$, is the minimum number of labels needed so that $G$ has a distinguishing labeling. In this paper, we present $O(n \log n)$-time algorithms that compute the distinguishing numbers

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

The Distinguishing Number and Posets, Part I [PDF]
, 2019 We introduce the distinguishing numbers of partially ordered sets. This study has given us the opportunity to apply classic results in poset theory to obtain results about this parameter.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

On distinguishing and distinguishing chromatic numbers of hypercubes [PDF]
, 2008 The distinguishing number D(G) of a graph G is the least integer d such that G has a labeling with d colors that is not preserved by any nontrivial automorphism.

Neighbor Sum Distinguishing Total Choosability of IC-Planar Graphs
Discussiones Mathematicae Graph Theory, 2020 Two distinct crossings are independent if the end-vertices of the crossed pair of edges are mutually different. If a graph G has a drawing in the plane such that every two crossings are independent, then we call G a plane graph with independent crossings

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
